Why CA Is 50% Of Solar Market. Good policy doesn’t happen by accident, it comes from effective policy representation. Tomorrow the solar industry is heading to Sacramento to push for the next year of policy including SB 100, the 100% RPS for California. I know your time and money is valuable but CALSSA has a PAC to help drive money into the political process. Please consider making a contribution.
Learning Lessons. Without knowing the details, you would expect NV Energy to stay as far away from the distributed solar policy as possible. After what happened a few years ago, it appears that NV Energy will continue to think in very short time spans about only itself. That’s why the headline about Sierra Club and NRDC joining NV Energy against energy choice seemed so wrong on the face of it.
Another Trillion To Go. Solar and wind have reached 1 terawatt in cumulative capacity which means that more than a trillion dollars have been invested. For most of those projects that means an interconnection, land rights and off-taker agreement are making that capital some of the most secure investment portfolios in the world. Let’s do it again, this time in less than a decade! 

Have a great day!

Over a million buildings in the U.S. have rooftop solar. These systems are extremely reliable: solar panels are guaranteed for 25 years, and inverters are guaranteed for 10-25 years. Our experience as a contractor since 2001 bears out the terrific reliability record of rooftop solar. Nevertheless, when inverters are past their expected lifetime we upgrade them to new models. Often we are able to replace two smaller inverters with one more efficient large inverter. When rooftop systems get very dirty (generally in areas without regular rainfall) we provide cleaning services. And not surprising to anyone who has ever tried to troubleshoot a home networking system, our most common customer service issue is with internet-based monitoring. To that point, current cellular-based monitoring systems have been 99.9% reliable (the only problems we have ever had have been with very weak mountain-top cell service). Like a 15 year old car that still runs, sometimes it makes good economic sense upgrading your solar system to the latest model. The same logic applies when considering an upgrade to a new solar system. Old panels were 14% efficient, and old inverters were 93-95% efficient. New panels have 20%+ efficiencies, and new inverters are up to 99% efficient. Moreover, because of our unreliable electric grid and transition to Time of Use electric rates, many customers are interested in upgrading to a battery storage system. For more about upgrading your solar system for your business or home – including applicability of the 30% tax credit on new equipment – Listen up to this week’s Energy Show.
