A fairly smart purchase for solar panels, especially when the electricity service has a fairly high cost. excellent friend. In my country they do not charge for electric energy and this has caused the deterioration of that company because it has become unsustainable, and based on that, the quality of the service has deteriorated for 20 years now, we have suffered the consequences with the constant blackouts. There was even a nationwide blackout for several days a couple of years ago, which left huge economic losses. Here we have adopted the use of electric plants as an alternative to the problem of electricity.
