Eco Factor: Carbon neutral homes designed to be powered on renewable energy.

After developing the best in solar technology, Sanyo has announced that it will soon be marketing solar-powered sustainable homes in Japan. The Sanyo Home will be equipped with a 3.78KW solar array and a 1.57KW Sanyo lithium-ion battery for backup.

The batteries will store excess solar energy, so that the house can remain off-grid during night or during overcast days. The home will also feature 10 LED light fixtures and a solar-powered heat-pump water heater to minimize energy loss.

With those many ecofriendly features in place, a 132sqm house will sell for $355,000, which is about $62,000 more than a comparable non-solar house.
