SolarCity To Sell Battery Storage With Every System Within 5-10 Years

At a private shindig in little town called New York City last week, SolarCity CEO Lyndon Rive and Chairman Elon Musk (Lyndon’s cousin and also the CEO, Chief Product Architect, and Chairman of Tesla Motors) made a few casual but potentially world-changing announcements, as is practically a habit with Elon.

Most notably, they stated that SolarCity would be including battery backup systems with every single one of its rooftop solar power systems within 5-10 years. Many of those, but not necessarily all of them, would come from Tesla’s planned gigafactory.

Even with the battery backups, Lyndon and Elon contend that a SolarCity installation will cost less than the price of electricity from the grid! (Them are some fightin’ words, someone once said.)

Solar panel costs and battery costs have been coming down fast in the past several years, and that cost reduction is projected to continue. Furthermore, SolarCity and Tesla aim to be in the center of it. SolarCity this year acquired Silevo in order to produce low-cost, high-efficiency solar panels in the US. And Tesla has started building a battery gigafactory in Nevada that, when completed, is supposed to produce as many lithium-ion batteries in a year as were produced all around the world in 2013. With economies of scale, costs should drop tremendously.

Will SolarCity really be delivering battery backup systems with all of its solar rooftops for a combined price that is lower than grid electricity in just 5-10 years? That’s a good possibility, but even if it isn’t, it will probably be doing so with many of its installations, and that’s going to have a dramatic, spiraling effect on energy markets worldwide. Exciting times.

    There are very few barriers to entry into the solar + battery storage market. Any mom and pop solar dealer across the country can enter this market with little capital investment.

    The grid tie battery backup inverter technology that is needed has existed since the late 1990s and is readily available today at low cost. Affordable battery tech already exists in the form of lead acid AGM.

    All it would take would be for one of the many new advanced battery technologies that are currently under development to hit the market and any advantage that Tesla batteries might have some day could easily be wiped out.
