Given that city gas is becoming more expensive, I would like to equip myself with solar panels to resell to EDF. Tell me if it's economical knowing that I'm in Tours right south, and advise me a brand of panels that has proven its effectiveness and its long "life" because there are so many manufacturers and so many subcontractors I do you trust in the choice because I think you are impartial.
Unfortunately, I can not tell you that the installation of solar photovoltaic collectors in order to return energy to EDF will be profitable for you immediately and will allow you to save on heating... The profitability of such an installation is done on 8 at 10 years old... Opt instead for thermal solar panels in boiler relief or for an air / water heat pump.
