Tesla Solar Roof - RGS Energy Powerhouse - Hanergy Solar - and others. The market definitely believes that you homeowners are interested in a product different than standard rectangle solar panels. In my history of residential solar construction, I met plenty of homeowners who were focused on aesthetics. The Harergy play is interesting for two reasons 1. Hanergy is a big company and can make something happen. 2. Hanergy is using a thin film solar cell, and they are one of the world's leaders at making a high efficiency thin film product. (more…)
If the cars being tracked in the below analysis were to degrade in a straight line from this chart, somewhere near 850,000 miles of driving is where the cars would hit 80% of the original mileage. I'm pretty sure I've not driven that many miles in the twenty years I've been behind a steering wheel. Every single analysis you've heard on the lifetime of energy storage is wrong. (more…)

A daily technical, financial, and political review/analysis of important green energy news. 1366 abandons plans for New York factory - DOE agreed to fund 1366 Technologies’ first large-scale solar manufacturing facility in upstate New York in 2011, six and a half years later no disbursements have been made, and the company has withdrawn from the loan guarantee process. Seems to me as if we're talking out of one side of the mouth by putting a tariff on all solar power imports, while ignoring directly supporting a company with the revenue from those tariffs. This suggests a failure in thinking through certain variables in this local solar content goal. India reportedly mulling halt to PV anti-dumping measures - If India cancels the anti-dumping investigation and refrain from implementing the provisional safeguards tariffs, global PV…

Tesla finally starts installing its massive ‘world’s largest solar rooftop array’ at Gigafactory 1 - This really is a huge building. Currently the world's largest rooftop solar project seems to be around 11-12MW. This system would be almost 7 times larger. With efficiencies having increased since the original announcement - unless the electricity utility pushes back, I suspect this projects will be larger than 70MW. (more…)
I wrote this yesterday. And as I wrote yesterday, and reflected on today, I started to realize the greatest reason Musk needs to own an inverter is because of the data network - not the few hundred million a year. This is the nature of a distributed power company. I'd guess Tesla/SolarCity have had very specific conversations on this topic with any vendors they use - lawyers write mean paragraphs regarding data rights. As TeslaSolar keeps growing, they're going to find more ways to sell their energy and related services. Having immediate access to distributed batfery storage via auto, home, commercial and Utility installations, plus solar generation to sell into active energy markets is worth a lot of money.
