Does Japan really have self-sufficient solar energy homes?
I have heard from a friend that in Japan, they have some houses that utilize solar energy to power the house and charge their electric car, and this is the only energy it ever needs. Is this true, and where can I learn more about it?
Nothing new. I have several friends in Mexico that have homes that are not connected to the electric system and use solar power with battery bank for storage.
This is well known old technology. Solar systems are great and works well. It is just very expensive relative to the electric power grid in most areas.
Japan should be very advanced in this area because they have had very high power cot for many years. It is primarily the cost effectiveness of solar that is holding it back. It is also not reliable in many areas due to cloudy weather and shorter days.
