what. this guy who got solar panels said he gets money from the grid company when he has excess energy. he gets paid for sharing his energy with the grid. but maybe there's something different in portugal. like when our grid detects the solar users are sharing their excess, the produce less energy from oil and gas. so they use the savings to pay the solar providers. or that energy is redirected to other users in the grid and they charge for it like with normally produced energy. and they share the profits with the solar provider.
