The numbers might work in my situation without needing to sell back to EDF etc, which doesn’t appear to be possible at the moment.
If the future of energy in France shifts from nuclear, utility costs could soar so solar with a life-time guaranty might prove an attractive alternative.
Tesla has not said that it will be in the Europe market but merely that it is positioning to start selling globally in 2018. This is a very new product.
I imagine Beijing would quickly move in with subsidies to manufacture similar products to keep China’s position as the world’s top solar power producer. However, Tesla is rewarding early-adopters with a lot of extras that competitors may not.
