Personally I don't care much about selling my surplus energy, as long as I am allowed to send my surplus power into the grid, because the installation I want cannot do zero feedback. I don't care about being paid, as long as my bill gets smaller. (And no, I don't want batteries.)
This is not just about money for me, but about being responsible, as I have installed a swimming pool, and the pump uses 1.2kW about 8-10 hours a day.
So, can I install a grid feeding installation without getting into trouble..?
This article http://www.andalucia.com/property/solarpower.htm says :
If electricity is generated from domestic photovoltaic panels any surplus electricity generated may be sold to the network. The electricity supply company must buy this electricity by law.
Any reference to that please?
