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

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry.
