History of SLI

The Institute is home to Solar 2000, one of northern California's largest solar arrays providing 160,000 kWh of clean renewable energy annually. Solar 2000 was conceived, designed and built in eight weeks and was a joint project of Real Goods, GPU Solar, Green Mountain Energy, and the Solar Living Institute. It is now owned by the Solar Living Institute.

The array cost $750,000 to build and received $430,000 in California energy rebates. It is made from 1,200 individual 110-watt solar electric modules with a total of 43,000 single crystal silicon cells. This clean-energy array displaces 1,600 tons each year of carbon dioxide emissions and generates 132kW, or 160,000kWh per year, of clean renewable energy. It sits on one-third of an acre, creates no pollution, is nearly maintenance free, and has a lifespan of over 50 years.

Solar 2000 is one of many solar and renewable energy displays at the Solar Living Center. Come and visit us to learn more.



In 1996, the first SolFest marked the grand opening of the Solar Living Center in Hopland, California. SolFest became part of the Solar Living Institute in 1998 when our organization was founded. SolFest is the premier renewable energy event in the western United States. The primary goal of SolFest is to enhance the mission of the Solar Living Institute by inspiring people to take action on their environmental concerns. Since the first SolFest in 1996, over 80,000 people have participated.


The Solar Living Institute is a 501 (c)(3) educational nonprofit organization offering instruction in solar training and sustainable practices.  Founded in 1998, we have been providing professional solar training and a wide array of sustainability courses for over 15 years. Our courses are taught by experienced practitioners who bring years of real world knowledge to the classroom with a focus on helping students prepare for job opportunities, start businesses, and live more sustainably.
