The internet has exploded with news about a new home battery system that can store solar energy – the Tesla battery. It is something that an average homeowner dreams about, a compact battery that can save energy, make the time and effort from installing bulky solar panels pay off, and will allow to use solar power no matter the weather outside, sunshine or rain. Sunny states like California offer incentives for homeowners to go green, however, it’s still not enough as the Tesla battery is rather expensive (starting at three thousand dollars). The battery can potentially save homeowners two dollars a day. This means that the solar power system will pay its owner back in about three years. Even if the cost of the battery will eventually fall as some predict, very few traditional energy customers will be able to afford it.
It will take time for this battery to become a household name. For now, consumers will have to rely on the more traditional PV industry products that have come down very significantly in cost in recent years due to the application of precise real-time thin film measurement tools that have made the production of solar panels more efficient.
