The Solar Potential of USA

According to a 1998 report by the United States Department of Energy, it has been discovered that available domestic solar energy, including biomass, was technically accessible regardless of cost amounted to 586,687 Quadrillion BTUs (Quads). Of that number, 95% was biomass. Coal represented the second largest resource, with 38,147 Quads. Predictions of how much solar power was economically possible to collect added up to 352 quads, compared with 5,266 quads from coal.

All the estimations that were used in the report were based on a prediction that the price of a barrel oil would become $38 in 2010. Additionally, they were also based on multiplied annual renewable resources by 30 for comparison with non-renewable resources. In 2007, the total annual energy consumption of the United States was about 100 Quads, which was less than 0.5% of what is theoretically available from sunlight.

Moreover, in 2012, a report from the National Renewable Energy Laboratory (NREL) described the technically available renewable energy resources for each state. In addition to that, the report estimated that urban utility-scale photovoltaics could supply 2,232 TWh per year, rural utility-scale PV 280,613 TWh per year, rooftop PV 818 TWh per year, and CSP 116,146 TWh per year. All these amounted for a total of almost 400,000 TWh per year, which was 100 times the current consumption of 3,856 TWh in 2011. For comparison, at the time, onshore wind potential was estimated at 32,784 TWh per year, offshore wind at 16,976 TWh per year, and the total available from all renewable resources was estimated at 481,963 TWh per year.

 

United States Government Support

A complete list of incentives can be found at the Database of State Incentives for Renewable Energy (DSIRE). A lot of solar power systems are grid-connected and use net metering laws to allow the use of electricity in the evening that was generated during the daytime. New Jersey is the state with the least restrictive net metering law while California is the one that has the most number of homes that have solar panels installed.

Many were installed because of the million solar roofs initiative, which entails a vision introduced back in 2007 where solar PV panels are to be installed on an additional million rooftops of home or businesses in the state of California by 2018.

In some states, like Florida, solar power is subject to legal restrictions that discourage its use.

Federal Tax Credit

The federal tax credit for solar was extended for eight years as part of the financial bailout bill, H.R. 1424, until the end of 2016. It was predicted that this will create about 440,000 jobs and 28 GW of solar power. Additionally, it was also predicted that this will lead to a $300 billion market for solar panels. This prediction did not take into account the removal of the $2,000 cap on residential tax credits at the end of 2008.

Moreover, a 30% tax credit is available for residential and commercial installations. For 2009 through 2011, this was a 30% grant instead of a tax credit, and at the time, it was known as the 1603 grant program.

The federal Residential Energy Efficient Property Credit, an income tax credit on IRS Form 5695, for residential PV and solar thermal was extended in December 2015 to remain at 30% of system cost (parts and installations) for systems that are put into service by the end of 2019, then 26% until the end of 2020, and then 22% until the end of 2021. This applies to a taxpayer’s principal and/or second residences, but this can’t be applied to a property that is rented out. There is no maximum cap on the credit, and the credit can be applied toward the Alternative Minimum Tax. Any excess credit (greater than that year’s tax liability) can be rolled into the following year.

The solar industry and utilities clashed extensively on renewal, but the solar industry won. The renewal is expected to add $38 billion of investment for 20 GW of solar.

Section 1603 Grants

President Barack Obama’s stimulus bill in 2009 created a program known as Section 1603 grants. This program was designed so as to give federal grants to solar companies for 30% of investments into solar energy. Since 2009, the federal government has given solar companies $25 billion in grant money through this program. However, the Section 1603 grant program expired in 2011.

The United States Treasury Department has been investigating solar companies for potential fraud since 2013. The department promised a report by June 2015, but the report had not been released as of 2016.

Solar America Initiative

The United States Department of Energy (DOE) announced on September 29, 2008, that it will invest $17.6 million, subject to annual appropriations, in six company-led, early-stage PV projects under the Solar America Initiative’s “PV Incubator” funding opportunity. The PV Incubator project is designed to fund prototype PV components and systems with the goal of moving them through the commercialization process by 2010. The 2008 award is the second funding opportunity released under the PV Incubator project. With the cost-share from the industry, which is at least 20%, up to $35.4 million would be invested in these projects. These projects would run for 18 months and are subcontracted through DOE’s National Renewable Energy Laboratory.

Most of the projects were to receive up to $3 million in funding, except Solasta and Spire Semiconductor which would receive up to $2.6 million and $2.97 million, respectively. Some of the projects under this initiative include:

  • Massachusetts-based 1366 Technologies developing a new cell architecture for low-cost, multi-crystalline silicon cells, which will enhance cell performance through improved light-trapping texturing and grooves for self-aligned metallization fingers
  • California’s Innovalight using ink-jet printing to transfer their “silicon ink” onto thin-crystalline silicon wafers so as to produce high-efficiency and low-cost solar cells and modules
  • Skyline Solar, also in California, developing an integrated, lightweight, and single-axis tracked system that reflects and concentrates sunlight over 10 times onto silicon cells
  • Solasta, in Massachusetts, working on a novel cell design that increases currents and lowers materials cost
  • Solexel, another California-based company, commercializing a disruptive, 3D high-efficiency monocrystalline silicon cell technology that dramatically reduces manufacturing cost per watt
  • Spire Semiconductor in New Hampshire developing three-junction tandem solar cells that better optimize the optical properties of their device layers. This company is targeting cell efficiencies over 42% using a low-cost manufacturing method.

The PV Incubator project is part of the Solar America Initiative (SAI), which plans to make solar energy cost-competitive with conventional forms of electricity by 2015 (grid parity).

The U.S. Department of Energy Solar Energy Technology Program (SETP) will achieve the goals of the SAI through partnerships and strategic alliances by focusing mainly on four areas. These are:

  • Market Transformation: activities that address marketplace barriers and offer the chance for market expansion
  • Device and Process Proof of Concept: R&D activities addressing novel devices or processes with a potentially significant performance or cost advantages
  • Component Prototype and Pilot-Scale Production: R&D activities emphasizing the development of prototype PV components or systems that are produced at pilot-scale with demonstrated cost, reliability, or performance advantages
  • System Development and Manufacturing: collaborative R&D activities among industry and university partners to develop and improve solar energy technologies

Another thing that is a part of the Solar America Initiative is the Solar America Showcase. For this activity, preference is given to large-scale, highly visible, and highly replicable installations that involve cutting-edge solar technologies or novel applications of solar.

SunShot Initiative

Announced by the Department of Energy in 2011, the SunShot Initiative aims to reduce the cost of solar power by 75% from 2010 to 2020. In great detail, this initiative’s goals are as follows:

  • Residential system prices reduced from $6/W to $1.50/W
  • Commercial system prices reduced from $5/W to $1.25/W
  • Utility-scale system prices reduced from $4/W to $1/W (CSP, CPV, and PV)

Additionally, the Department of Energy announced a $29 million investment in four projects that would help advance affordable and reliable clean energy for American families and businesses. The $29 million would be separated into two investments:

  • $21 million investment over five years to design plug-and-play PV systems that can be purchased, installed, and operational in one day
  • $8 million investment in two projects to help utilities and grid operators better forecast when, where, and how much solar power will be produced at U.S. solar energy plants

Other projects under the SunShot Initiative are the following:

  • Fraunhofer USA’s Center for Sustainable Energy Systems in Cambridge, Massachusetts developing PV technologies that allow homeowners to easily select the right solar system for their house and install, wire and connect to the grid
  • North Carolina State University leading a project to create standard PV components and system designs that can adapt simply to any residential roof and can be installed and connected to the grid quickly and efficiently
  • IBM Thomas J. Watson Research Center in Armonk, New York leading a new project based on the Watson computer system that uses big data processing and self-adjusting algorithms to integrate different prediction models and learning technologies

All these projects are working with the Department of Energy and the National Oceanic and Atmospheric Association to improve the accuracy of solar forecasts and share the results of this work with industry and academia.

State and Local

There have been numerous instances throughout the years that showcase the efforts that state and local government officials have undergone to make solar possible. The following are the most well-known of these instances:

  • Governor Jerry Brown has signed legislation requiring California’s utilities to get 50% of their electricity from renewable energy sources by the end of 2030.
  • The San Francisco Board of Supervisors passed solar incentives of up to $6,000 for homeowners and up to $10,000 for businesses. Applications for the program started on July 1, 2008. In April 2016, they passed a law that requires all new buildings below 10 stories to have rooftop solar panels. This made San Francisco the first major U.S. city to do so.
  • In 2008, Berkeley initiated a revolutionary pilot program where homeowners are able to add the cost of solar panels to their property tax assessment and pay for them out of their electricity cost savings. In 2009, over a dozen states passed legislation allowing property tax financing. All in all, 27 states offer loans for solar projects.
  • The California Solar Initiative has set a goal to create 3,000 MW of new, solar-produced electricity by 2016.
  • New Hampshire has a $3,750 residential rebate program for up to 50% of system cost for systems less than 5 kWp ($6,000 from July 1, 2008, until 2010).
  • Louisiana has a 50% tax credit up to $12,500 for the installation of a wind or solar system.
  • New Jersey law provides new solar power installations with exemptions from the 7% state sales tax and from any increase in property assessment (local property tax increases), subject to certain registration requirements.

Feed-in Tariff

According to experience, a feed-in tariff is both the least expensive and the most effective means of developing solar power. This is because investors need certainty, and a feed-in tariff definitely gives them that.

California enacted a feed-in tariff that began on February 14, 2008, while Washington has a feed-in tariff of 15¢/kWh which increases to 54¢/kWh if components are manufactured in the state. Hawaii, Michigan, and Vermont also have feed-in tariffs.

In 2010, the Federal Energy Regulatory (FERC) ruled that states were able to implement above-market feed-in tariffs for specific technologies.

Solar Renewable Energy Certificates

In recent years, states that have passed the Renewable Portfolio Standard (RPS) or the Renewable Electricity Standard (RES) laws have relied on the use of solar renewable energy certificates (SRECs) to meet state requirements. They have achieved this by adding a specific solar carve-out to the state RPS. The first SREC program was implemented in 2005 by New Jersey. Soon enough, this program has expanded to several other states, including Maryland, Delaware, Ohio, Massachusetts, North Carolina, and Pennsylvania.

SREC offers many advantages, but one of its major problems is the lack of certainty for investors. A feed-in tariff provides a known return on investment, but an SREC program provides only a possible return of investment.

Power Purchase Agreement

In 2006, investors started offering free solar panel installation in return for a 25-year contract. They also began offering a Power Purchase Agreement (PPA), which is a contract between two parties — one which generates electricity (the seller) and one which is looking to purchase electricity (the buyer).

By 2009, over 90% of commercial PV installed in the United States were installed using a PPA. About 90% of the PV installed in the United States is in states that specifically address PPAs.

New Construction Mandates

In March 2013, Lancaster California became the first U.S. city to mandate the inclusion of solar panels on new homes, requiring that every new housing development must average 1 kW per house.

PACE Financing

The Property Assessed Clean Energy (PACE) Financing is a means of financing energy efficiency upgrades, disaster resiliency improvements, water conservation measures, or renewable energy installations of residential, commercial, and industrial property owners. This innovative financing arrangement lends money to a homeowner for a solar system, to be repaid via an additional tax assessment on the property for 20 years. This kind of financing arrangement allows the installation of the solar system at “relatively little up-front cost to the property owner.”

The principal feature of this program is that the balance of the loan is transferred to the new owners in the event the property is sold, and the loan is paid for entirely through electric bill savings. Unlike a mortgage loan, no funds are transferred when the property is sold — only the repayment obligation is transferred.

PACE programs are currently operating in eight states, California, Colorado, Florida, Maine, Michigan, Missouri, New York, and Wisconsin. Additionally, they are on hold in many other states.

Current Status of Solar Power in the United States

Published on June 2019, the report from the Solar Energy Industries Association and Wood Mackenzie Power and Renewables, a market research group, have discovered that the first quarter of 2019 was the strongest in the U.S. solar industry’s history. A total of 2.7 GW of solar capacity was added to the grid at this time.

Aside from that, new solar installations should grow 25% from 2018, thus amounting to 13.3 GW. This bounceback — after solar installations dipped 2% last year — was driven by larger-scale utility solar projects, which account for 61% of the first quarter’s growth.

This development is a remarkable change from what was expected last year when President Trump announced that he was putting tariffs on imported solar cells and modules. During this time, the industry was worried that the tariffs would hinder solar. However, solar installations shot past the 2-million mark this year instead.

Moreover, the industry expects this growth to continue well past 2019. A number of U.S. utilities have solar projects in the works, and they should be a reality by 2024. And both residential and non-residential solar markets have grown tremendously over the years. Overall, solar power in the United States is currently on an uphill climb.

Solar Panel

Wholesale Solar Panels For Sale

Homeowners and all types of businesses these days are seeking ways to cut down on their power consumption bill and reduce the overall operational cost. For this purpose, solar energy is the best alternative for them to be cost-effective and energy-efficient. 

In the upcoming decade, energy costs are estimated to become double. Solar panels offer a smart energy solution for home and business owners and allow them to buy electricity at a set price per unit. This means homes and commercial properties of consumers will never be exposed to increased energy prices again, which will financial forecasting a lot easier. 

As a solar installer, it is a lucrative opportunity for your business to convey your message to both residential and commercial consumers that the longer they wait, the more costs they will have to pay for electricity. 

In the current scenario, for example, commercial prices for solar have dropped by 58% since 2012. However, the latest policy changes suggest that it will not be the case in the future anymore. 

In the US, the federal investment tax credit (ITC) for solar is currently equal to 30% of the amount of an eligible installation. It means if you invest $40,000 in solar, you could receive a $12,000 tax credit. 

However, the rate of ITC rate will go down to 26% in 2020, 22% in 2021, and 10% after 2021. Meanwhile, electricity prices will continue to increase year-over-year. So, the sooner consumers adopt solar energy, the more they can save.

The Major Types of Solar Modules

Most solar modules are currently produced from crystalline silicon (c-Si) solar cells that are made of multi-crystalline and monocrystalline silicon. In 2013, crystalline silicon accounted for more than 90% of worldwide PV production. Meanwhile, the rest of the overall market is made up of thin-film technologies that are using cadmium telluride, CIGS, and amorphous silicon.

An emerging third generation of solar technologies makes use of advanced thin-film cells. They produce a relatively high-efficiency conversion for the low cost compared to other solar technologies.

Additionally, high-cost, high-efficiency, and close-packed rectangular multi-junction (MJ) cells are preferably used in solar panels on spacecraft since they offer the highest ratio of generated power per kilogram lifted into space. MJ cells are compound semiconductors and are made of gallium arsenide (GaAs) and other semiconductor materials.

Another emerging PV technology using MJ cells is concentrator photovoltaics (CPV). CPV also generates electricity from sunlight, but unlike conventional photovoltaic systems, it uses lenses or curved mirrors to focus sunlight onto small, highly efficient, MJ solar cells. Additionally, CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency.

Thin Film

thin-film solar cell is a second-generation solar cell that is made by depositing one or more thin layers or thin-film (TF) of photovoltaic material on a substrate, such as glass, plastic, or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si).

In rigid thin-film modules, the cell and the module are manufactured in the same production line. The cell is created on a glass substrate or superstate, and the electrical connections are created in situ, a so-called “monolithic integration.” The substrate or superstate is laminated with an encapsulant to a front or back sheet, usually another sheet of glass. The main cell technologies in this category are CdTe, a-Si, a-Si+uc-Si tandem, or CIGS (or variant). Amorphous silicon has a sunlight conversion rate of 6-12%.

Flexible thin-film cells and modules are created on the same production line by depositing the photoactive layer and other necessary layers on a flexible substrate. If the substrate is an insulator, like polyester or polyimide film, then monolithic integration can be used. But if it is a conductor, then another technique for electrical connection must be used. The cells are assembled into modules by laminating them to a transparent colorless fluoropolymer on the front side (usually ETFE or FEP) and a polymer suitable for bonding to the final substrate on the other side.

Crystalline Silicon

Crystalline silicon (c-Si) is the crystalline forms of silicon, either multi-crystalline silicon (multi-Si) that consists of small crystals or monocrystalline silicon (mono-Si) which is a continuous crystal. Crystalline silicon is the dominant semiconducting material that is used in photovoltaic technology for the production of solar cells. These cells are then assembled into solar panels as part of a photovoltaic system to generate solar power from sunlight.

Solar cells that are made of crystalline silicon are usually called conventional, traditional, or first-generation solar cells. This is because they were developed in the 1950s and remained the most common type up to the present time. Because of the fact that solar cells made of crystalline silicon are produced from 160-190 micrometer thick solar wafers, they are oftentimes called wafer-based solar cells.

Furthermore, solar cells that are made from c-Si are single-junction cells and are generally more efficient than their rival technologies, which are the second-generation thin-film solar cells, such as CdTe, CIGS, and amorphous silicon. In particular, amorphous silicon is an allotropic variant of silicon, and amorphous means “without shape” to describe its non-crystalline form.

Organic Solar Cell

An organic solar cell (OSC), also known as a plastic solar cell, is a type of photovoltaic that makes use of organic electronics, which is a branch of electronics that deals with conductive organic polymers or small organic molecules, for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect. Most organic photovoltaic cells are polymer solar cells.

The molecules used in organic solar cells are solution-processable at high throughput and are cheap, thus resulting in low production costs to fabricate a large volume. Combined with the flexibility of organic molecules, organic solar cells are potentially cost-effective for photovoltaic applications. In addition to that, the optical absorption coefficient of organic molecules is high, so a large amount of light can be absorbed with a small number of materials, usually on the order of hundreds of nanometers.

The primary disadvantages that are associated with organic photovoltaic cells are low efficiency, low stability, and low strength compared to inorganic photovoltaic cells such as silicon solar cells.

Additionally, when compared to silicon-based devices, polymer solar cells are lightweight (which is important for small autonomous sensors), potentially disposable and inexpensive to fabricate, flexible, customizable on the molecular level, and potentially have a less adverse environmental impact. Polymer solar cells also have the potential to exhibit transparency, thus suggesting applications in windows, walls, and flexible electronics.

The inefficiency and stability problems that polymer solar cells have, along with their promise low costs, actually made them a popular field in solar cell research. As of 2015, polymer solar cells were able to achieve over 10% efficiency via a tandem structure. In 2018, a record-breaking efficiency for organic photovoltaics of 17.3% was reached via a tandem structure.

Monocrystalline vs. Polycrystalline

As the name suggests, both monocrystalline and polycrystalline are types of solar cells that are made from crystalline silicon. To start with, monocrystalline is the oldest and most developed of the current solar cell technologies. Monocrystalline panels are created from a single continuous crystal structure. As such, they can be identified as the solar cells that all appear as a single flat color.

On the other hand, polycrystalline solar panels are made from silicon as well. However, instead of using a single crystal of silicon, manufacturers melt many fragments of silicon together to form the wafers for the panel. Because of this, polycrystalline solar panels are also sometimes referred to as “multi-crystalline” or many-crystal silicon. Additionally, polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.

Between the two, monocrystalline solar panels are generally thought of as the premium solar product. This is because the cells are composed of a single crystal, thus allowing the electrons that generate a flow of electricity to have more room to move. In other words, monocrystalline panels have higher efficiencies, and they also have sleeker aesthetics.

Meanwhile, since polycrystalline have many crystals in each cell, there is less freedom for the electrons to move. As a result, they have lower efficiency ratings than monocrystalline panels. That said, however, polycrystalline solar panels have the main advantage of a lower price point. That is why they are still popular in the solar industry as of right now.

Transparent Solar Panel

As the name suggests, a transparent solar panel is a solar panel that is either partially or completely transparent. Conventional solar panels absorb sunlight and convert photons into usable energy. The difficulty with making transparent solar panels is that the sunlight passes through the transparent material. This means that the process that generates the electricity in the solar cell cannot be started because no light is absorbed.

As of right now, there is still a long way to go before transparent solar panels become a reality. But there have already been innovations that will definitely lead to the progress of this particular technology.

Nanoparticle Solar Panels

Silicon nanoparticles exhibit many useful properties — some of which include an active surface state, low bulk density as well as unique photoluminescent and biocompatible properties. As a result, these nanoparticles are usually incorporated into lithium-ion batteries, solar energy cells, micro, and integrated semiconductors, and luminescent display devices. When applied for solar energy products, the size and microstructure of silicon nanoparticles, including their luminescence and quantum efficiency properties, are highly specific.

Nanotechnology offers a lot of benefits for the manufacturing of solar panels. In particular, it reduces manufacturing costs as a result of using a low-temperature process instead of the high-temperature vacuum deposition process that is typically used to produce conventional cells made with crystalline semiconductor materials. Additionally, it also reduces installation costs, achieved by producing flexible rolls instead of rigid crystalline panels.

As of right now, available nanotechnology solar cells are not as efficient as traditional ones, but the lower cost offsets this. In the long run, nanotechnology versions should both be lower cost and, using quantum dots, should be able to reach higher efficiency levels than conventional ones.

Infrared Plastic Solar Cell

Researchers at Idaho National Laboratory, along with partners at Lightwave Power Inc. in Cambridge, MA and Patrick Pinhero of the University of Missouri, have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. These nanoantennas target mid-infrared rays, which the Earth continuously radiates as heat after absorbing energy from the sun during the day. Aside from that, double-sided nanoantenna sheets can also harvest energy from different parts of the sun’s spectrum. This is an advantage considering that traditional solar cells can only use visible light, thus rendering them idle after dark.

With this, the next generation of solar cells could be produced using a new semiconductor alloy that can capture the near-infrared light on the leading edge of the visible light spectrum. In other words, this infrared plastic solar cell can turn the sun’s power into electric energy even on a cloudy day. Just like the nanoparticle solar cells, infrared plastic solar cells also make use of nanotechnology.

UV Solar Cell

Japan’s National Institute of Advanced Industrial Science and Technology (AIST) has succeeded in developing a transparent solar cell that utilizes ultraviolet (UV) light to generate electricity but allows visible light to pass through it. This transparent, UV-absorbing system was achieved by using an organic-inorganic heterostructure made of the p-type semiconducting polymer PEDOT: PSS film deposited on a Nb-doped strontium titanate substrate.

These solar cells are only activated in the UV region and result in a relatively high quantum yield of 16% electron/photon. Future work in this technology involves replacing the strontium titanate substrate with a strontium titanate film deposited on a glass substrate in order to achieve low-cost, large-area manufacturing.

How Supplying Quality Solar Panels Can Expand Your Business?

Solar energy saves money for residential and commercial consumers that they would otherwise spend on electricity bills. In fact, the savings on energy bills are substantial. 

According to a survey carried out by SunPower a couple of years back, nearly 87% of businesses said that saving money is one of the major reasons for initiating solar projects. Some of the projects forecasted to save thousands of dollars in electricity costs during the lifespan of their solar system. That kind of saving surely leaves a positive impact on a business’s bottom line.

This is why opting for solar is not just a financial decision, it is a major environmental aspect as well. Both residential and commercial consumers look for saving their costs of electricity in the long run. The only difference is businesses that have a focus on sustainability are likely to experience powerful brand effects and customer loyalty. The reason is using solar panel systems and promoting renewable and sustainable energy make a strong statement to customers. 

The Cost Factor of Solar Business

You are required to shell out substantial prices if you are looking to buy solar panels from the retail market and supply them to your customers. Also, the profit margin will be narrow due to the prevalent high prices in the market. 

On the other hand, to obtain shipments of wholesale solar panels in bulk quantity, the cost will be significantly lower. If you seek franchise opportunities, for that too, you need to pay a large sum just to gain access to the process. This is why getting into partnerships with one or multiple solar panel manufacturers will provide you more options to obtain panels of various brands.

How to Make Your Solar Business more Profitable?

Your biggest costs to run your solar installation business are purchasing solar panels from the distributor and paying your staff.
