As long as the sun shines, I am energy neutral. 8 big solar panels and pseudo to spare... and no cars but e-bikes here.. 8 solar panels is enough to cover a 4 human sized family, including the airco. (well, strictly speaking, one human three females, six if you include dogs and cat which all belong to the same species) These are a money maker that compensate for our internet use. We make money out of these panels.
