Sharp’s new solar battery allows you to use solar power all day long

Sharp, partnering with battery specialist Eliiy Power, will soon start selling the world’s first storage battery for household electricity systems.

These new batteries will allow houses with solar panels to store the power generated by the sun overnight (a full day and a half if necessary), allowing them to operate independently of a power grid.

The companies involved hope that reducing the reliance on traditionally-generated power will help reduce Japan’s greenhouse emissions. Hopefully these batteries will make it to the States so we can do the same.

The price is expected to be around ¥500,000 (about $4,650) when the battery is released next year.

This new battery is expensive, but would pay for itself over time seeing as solar power is free after all of the equipment is installed. Besides, you’ll get that warm, fuzzy feeling knowing that you’re polluting less.
