Wow I really liked how the solar panels turned out, I am thinking of installing a backup system, maybe something small like an inverter charger, 2 batteries of 100ah or 200ah, mppt controller, everything will depend on the consumption, I will have to study it. I was thinking about solar panels but since I live in an apartment it is very difficult to get everyone to agree. Here in Venezuela although electricity is cheap, we have constant blackouts. 😃
