It’s interesting to watch how the changing economics in the rooftop solar industry are changing the political landscape as well.
Several published reports have described changes in the industry group, The Alliance for Solar Choice, which is facing the departure of Solar City, the large publicly traded solar company that has been one of the alliance’s key members.
The Las Vegas Sun reported Solar City’s break with TASC last month (“SolarCity cutting ties with rooftop solar advocacy group“), citing differences in approaches for dealing with regulators and political authorities on key energy issues.
TASC has become known for its “scorched earth” political tactics, aggressively filing suit and publicly attacking regulators struggling to develop pricing mechanisms that will allow continued solar growth to continue without overloading existing electrical grids.
But Solar City is now taking a different direction, looking at a less confrontational approach (“Is TASC splintering the rooftop solar industry?“).
Solar City announced a tie-in earlier this year with the new battery systems being built by Tesla, the electric auto maker. Elon Musk,the CEO of Tesla, is also SolarCity’s chairman and biggest shareholder (see “SolarCity, Tesla roll out batteries that store sun’s energy for nighttime“).
And the promise of new battery technologies matched to rooftop solar systems promises to dramatically change the solar industry over the next several years.
Solar City apparently sees the potential for this market, which promises a way around the divisive debate over net metering, and wants to play a more constructive role in discussions with utilities and regulators across the country.
For example, as I understand it, one of Hawaiian Electric’s options offered in their plan to replace net metering would allow homeowners to install relatively self-contained rooftop solar systems with battery backups that would store power to be used in the evenings while remaining connected to the grid. Homeowners would only pay the utility for power they drew when their own systems did not provide enough electricity for their own use.
There’s also growing criticism of rooftop solar companies with business models that have relied on getting consumers to enter into long-term leases and power purchase agreements, usually for 20 years (“Rooftop Solar Shines Light On Bad Business Practices“).
Former PUC chair Mina Morita’s always interesting Energy Dynamics blog has been tracking these industry dynamics (for example, see her post, “Moving On To A Broader Approach: Rooftop Solar Versus Distributed Energy Resources“). This can be dense reading, with lots of supporting data, but well worth the effort.
