I "sell" the excess to the electric company, but the Spanish law compensation system is not good, is monthly basis, so I've excess electricity 8-9 months per year that I never get paid for and 3 months that I pay some electricity + the gas bill. Now I will change that.

We should trade stories off-list... I've gone down the 
self-generation/self-consumption rabbit hole too :-).
