Enphase Charges Into the Energy Storage Market

Enphase didn’t exhibit at last year’s Solar Power International, but the microinverter specialist has traveled to Las Vegas this year with an improved microinverter — and a bit of a surprise. 5th generation microinverter Paul Nahi, Enphase’s CEO, said the firm’s fifth-generation microinverter is its “most technologically advanced microinverter — this was not even possible to

Big Box Retail’s Latest Bright Idea: Solar Power

Big companies are finally beginning to see the light. Over the past two years, the top 25 corporate solar users in America have more than doubled their capacity, according to a new report by the Solar Energy Industries Association. Cumulatively, these companies produced enough electricity last year to power more than 115,000 homes. Leading the pack by

Off-Grid Solar is Going to be HUGE

Everywhere you look, the off-grid clean energy market is booming. Sub-Saharan Africa is seeing 300 percent compound annual growth in off-grid lighting; Bangladesh is putting up 30,000 to 40,000 solar home systems every month; and d.light, a for-profit seller of solar lights, recently reached its 1 millionth customer. If these numbers haven’t raised the attention of institutional investors,

Solar Landfills: One Person’s Trash Is Another’s Treasure

Green Mountain Power just broke ground on a 2 MW photovoltaic plant in Rutland, Vermont. While some other large PV systems planned for the area have met with strong opposition(some residents worry large, ground-mount solar arrays will be an eyesore on the state’s pastoral landscape), this project seems to be welcomed with open arms. Why? It’s

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.

How Carla Peterman and the CPUC will Make Calif. an Energy Storage Leader

Energy storage has been hailed as a “holy grail” for clean energy. Through energy storage, renewable power can be tapped whenever it’s needed, not just when nature cooperates. This means that utilities can overcome the intermittent production of renewable energy while controlling power supply and demand. And residential homeowners capturing unused electricity from rooftop solar
