How Apple is making money off of its landmark solar deal

There’s a key aspect of Apple’s high-profile solar deal in California that’s been largely overlooked—until now. When Apple announced to the world last month that it would be spending an eye-popping almost $850 million to buy solar power from a solar farm to be built in central California, clean energy fans naturally cheered. But there was another

Investors back startup that sells offgrid battery & solar panels

Batteries paired with solar panels aren’t just intriguing customers in the U.S., Europe and Japan looking to ditch their utilities. People are slowly adopting batteries and solar panels in offgrid markets, too, using their cell phones to make reoccurring micropayments and using solar energy to replace kerosene lanterns. This week startup Fenix International — which is based in

Leased solar panels can complicate — or kill — a home sale

Can going green by leasing solar panels for your roof cost you money — or give you headaches — when you go to sell the house? Possibly both. Say you get pitched by one of the growing number of companies offering solar panels at no upfront cost that they claim will save you lots of

Solar Power to develop floating photovoltaic projects

Solar Power Inc. said Thursday it signed a partnership to develop 50 megawatts of floating solar photovoltaic projects in California, three other states and Mexico. Floating photovoltaic arrays are relatively new technology for irrigation ponds, reservoirs and water treatment plants. They are getting notice because they don’t take up valuable farmland or expensive real estate. There

renewables and the grid

Three trends that get the grid to 70% renewables by mid-century

For a decade, electricity system operators have wrestled with how to respond to the challenge of growing renewables, but a change has come. System operators are now looking to solar and wind as a solution — rather than the problem — in their drive for more affordable reliability. But realizing the grid of the future necessitates

Community Solar: Key Considerations in Designing a Successful Program

The first community solar programs were started nearly a decade ago, and, as the name suggests, the early efforts were led by communities — neighbors, small towns, places of worship — in each case, a group of people dedicated to building solar systems and sharing the benefits of the electrical output. From these humble beginnings,

This Startup Lets People Without Roofs Get In On The Solar Power Boom

Most apartment dwellers who want to use solar power probably won’t find it easy to convince their landlord to install panels on the roof. But there’s another option: A new startup will let anyone invest in solar panels remotely—and then get paid quarterly checks for the energy they produce. “We’ve found in research that about 80% of

Solarize South Carolina Campaign Aims to Rev Up SC’s Home Solar Industry

Thanks to the launch of a new grassroots campaign in South Carolina, the longtime solar laggard could be poised to triple its installed capacity among homes and small businesses. Today, clean energy nonprofit group SmartPower officially kicks off a Solarize bulk discount buying program. Solarize South Carolina aims to inflate South Carolina’s solar capacity among homes and

Wind and solar supply chains thrive in Midwest states

Wind and solar energy support about 30,000 jobs at about a thousand companies in Wisconsin, Illinois and Iowa, according to a series of reports released by the Environmental Law & Policy Center over the past two weeks. The reports show the jobs created not only by the manufacture of wind turbine components, the building of wind farms

Solar Power To Become Cheapest Source Of Energy In Many Regions By 2025

Solar power still amounts for a small share of net electricity generation around the world. In the USA, for instance, as of December 2014 it was responsiblefor just 0.45% of the total electricity produced. Things are changing quite quickly, however, and if the German think tank Agora Energiewende is right, faster than expected. The main obstacle to a

The Relationship Between SREC Prices and Solar Leasing

Several forums, including this one, covering residential solar developments have commented on the volatility of SREC markets in some states. But few have yet to note the potentially tremendous impact on solar leasing, and residential solar adoption in general, in those SREC states experiencing severe fluctuations in pricing.

MIT, Stanford researchers develop new kind of tandem solar cell

Researchers at MIT and Stanford University have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations, the researchers say. The

Attacks Against Solar, Wind Keep Coming, SEIA Fights Back

Earlier this month The Energy Information Administration (EIA) released a narrowly focussed report on certain subsidies to the energy industry at the behest of Reps.

Trees vs Solar

The endless debate of trees vs. solar

Yesterday, a story ran in the Asbury Park Press about the solar project plans of Six Flags Great Adventure. To power their popular New Jersey amusement park, Six Flags plans to build the state’s largest solar farm. The cost? To begin with, 18,000 trees. This brings up a contentious debate among environmentalists and proponents of renewable

Elon Musk’s next disruption: residential energy storage

On top of taking the auto industry by storm, Elon Musk might well be on the road to disrupt the electric power distribution industry, as well, developing a battery storage system for the residential market.

New 3-phase microinverter for large scale applications

Microinverter expert APS is now shipping its new 3-phase YC1000 inverter, which can handle 277/480 grid voltages and up to four PV modules per unit. Up to eleven units can then be linked in a single 15 A circuit. The maximum output of one YC1000 lies at 900 W and additionally it has integrated ground

The greatest country on Earth, as it likes to bill itself, America is currently shut down, thanks to political intransigence and public ignorance.

Get more out of your solar power system by using water as a battery

When the sun shines at its brightest, many of Australia’s 1.3 million homes with rooftop photovoltaic (PV) solar panelsgenerate more electricity than they use. When this happens, excess electricity is exported to the grid. In the old days (say, about 2009), most householders would be pretty happy with this, given that in Victoria, for example, it would
