$16 Million For “Off Grid Electric” From SolarCity

“Off Grid Electric” explains that it delivers 50 times more light for less money than the norm in the markets it serves. The people it supplies are often using kerosene lamps to light their homes. Furthermore, it is more than light that these people need. Pre-pay solar energy from Off Grid Electric gives them electricity to charge

In This State: Leigh Seddon’s 35 years in the solar power biz

Leigh Seddon, you could say, made hay while the sun shone. For 35 years he has been a solar enthusiast, visionary, entrepreneur and consultant – in short, one of Vermont’s chief proponents of harnessing sunshine to create electricity. He has seen solar grow in Vermont from the simple photovoltaic systems installed by off-grid back-to-the-land types

TEP’s ‘rent-a-roof’ would offer cheap solar power for homes

Arizona’s most abundant natural resource could arguably be the sun. Tucson Electric Power wants to start using more of it by enlisting homeowners to lend it their rooftops, potentially taking business away from smaller solar companies. The project is still on the drawing board, but it may be a reality in the next couple of
