I have to change my water heater. Can I replace electricity with a solar panel?
Yes, you can fully power a storage water heater with solar panels. It should have an area of 3 to 5 m2 depending on the region. This installation will provide 50 to 70% of the energy for a cumulus of 200 liters for 4 people knowing that the average consumption of hot water is 50/60 liters per person per day. But as the total consumption of the water heater is not total, it is necessary to add a resistance. So you need a special water heater called "solar". You can benefit from a 50% tax credit on the equipment, subject to the usual conditions.
