Solar rooftops can strengthen an aging power grid and save Californians $1.4 billion every year, says SolarCity


SolarCity, the largest residential solar installer in the US, employs a grid engineering team to integrate its systems and evaluate the impact on the grid. The company decided this week to publish the team’s findings in a white paper titled: “A Pathway to the Distributed Grid”.

The report describes in detail how embracing distributed energy resources (DERs) – like rooftop solar batteries and advanced inverters – offers a superior economic alternative to today’s centralized grid design.

Based on its calculations, the company asserts that if California and its utility sector were to fully embrace distributed resources like rooftop solar, the state would see net societal benefits of more than $1.4 billion per year.

What SolarCity calls “societal benefits” include “improved flexibility in grid planning and operations, increased affordability and consumer choice, and improved grid reliability and efficiency, not to mention less reliance on fossil fuels”.

The company says that solar customers and non-solar customers alike can reap the benefits of more distributed energy resources integration on the grid.

    Nice, but it only works in California (and maybe some other places) where there’s no significant difference between winter and summer. This is my problem with Elon’s “solar revolution plan”. It can work… in CA and some other places… but in rest of the world? The winters can be cloudy and foggy for weeks in the northern half of Europe. When a 6 kWp system only generates a few hundred Wh (maybe 1-2 kWh) power daily, but the heat pump and other major consumers are running, and this is going on day-by-day, you’re better to have a thousand kWh reserved power in batteries for winter at least. To do this you should have some (100) Powerwalls. And this is just one household.

    I agree with commenter r2d. Fred, it would be better if you could do an analysis of whether solar city ‘s calculation makes sense, as much as I love the company,I hesitate to take what companies promote, at face value.
