Elon Musk made headlines this week announcing his plan to develop Tesla’s battery technology for home energy use.
Tesla’s mega factory will soon be churning out their super efficient lithium-ion battery packs for homes. The battery pack will reportedly be sold independently as well as being coupled with Musk’s decentralized green energy company Solar City.
Even if you don’t have solar panels or a way to charge home battery banks, they can still pay for themselves quite quickly. Most electric companies charge a much lower rate at off-peak hours – as little as a third of the peak rate. So you can charge your battery pack when the rates are cheapest, and use that stored energy when the rates are highest.
Imagine saving two-thirds on your current electric bill. Most households would save a few thousand dollars a year. Battery banks would likely pay for themselves very quickly just using this method alone. Add in a generator, solar panels, or wind mills to charge them and decentralized off-grid electricity seems quite practical.
However, since Tesla’s venture is at least six months away, I wondered what current options exist; and Tesla may have some stiff competition.
Aquion Energy manufactures its proprietary Aqueous Hybrid Ion batteries to provide affordable off-grid power storage. These eco-friendly batteries are made with saltwater, cost less and last up to ten times longer than traditional batteries currently used in solar home systems, and are already linked together in a bank for optimum charging speeds and easy installation.
