On an earlier post I had mentioned that a electric car manufacturer other than Tesla was doing research to see what they could possibly do with their cars batteries after their cars life had expired but not the batteries life. They were looking at using them to store power in the home solar market. Tesla recently announced in a Steve Jobs like product announcement, they are producing special batteries for solar systems used in homes and business.
Recent advancements in solar panel construction in chemical and materials has made solar panels more affordable. Now combining the Tesla battery and panel advancements, the solar energy systems will get payback earlier. Electric cars , homes and business will charge off the sun, thus making a smaller carbon foot print. This will be important for this and generations to come. Tesla Energy Company Website
