I do not agree, and I will illustrate my point with the example of a friend who had to choose between paying € 5.000 to connect his wooden house to EDF or equipping himself for € 2000 with a wind turbine, of photovoltaic panels, batteries and inverter.chatelot16 wrote:For those who have already done their utmost to reduce their electricity consumption, photovoltaic production for self-consumption is no longer of much use
Every once in a while he gets a better new battery or an additional solar panel, but it costs him considerably less than the privilege of paying a subscription and electricity bills.
Its renewable electricity production is therefore extremely relevant while it consumes very little and is constantly in a situation of overproduction, not being connected to EDF ...
Again, I don't agree ...chatelot16 wrote:Then you have to know what you want: by installing a stronger power it will happen more often to give it to EDF, but whatever that increases the savings on your bill anyway because it will produce more in the morning in the evening and the days of low sun
a power installed 2 times too high does not double the return on investment time, it just increases it a little
If you are connected to EDF, it is MANDATORY to have an approved installation (safety and consuel standards).
In this case, an electricity buyback contract will be signed with EDF Obligation to Purchase.
Two possibilities,:
1 / Total resale of production (ban on storage and self-consumption)
2 / Resale of surplus (self-consumption of production and resale of surplus).
There will therefore be no electricity supplied as a gift to EDF as you state ...
In addition, a well-negotiated installation (installer, financing, aid and subsidies) pays off faster when its power is high for reasons of economy of scale ...
