Solar radiator battery




by sandrine1978 » 18/04/21, 16:08

Hello

I would like to plug my auxiliary heater into a solar power supply, or something else that could prevent me from using it on electricity.

Could you tell me which devices I can buy please?

Thank you in advance for your reply

Hello, given the power of a radiator, I doubt that you will be able to make substantial savings by buying (at the pif) 1000W of solar panels.

2000W !!! Forget the solar panels.

There, you will increase them! Best to use it just when you don't need it. It is as stated, a backup heater for the bathroom (I guess).

Welcome Sandrine!
Photos of your windows from the inside and the building from the outside?
Is there domestic hot-water or is it an electric water heater? How long do you plan to live where you are? What is the living room flooring?

Using solar panels to heat the winter is not a good idea, because in winter the days are short, the sun is low and the weather is not often sunny - except in the South-South of France. . but in the land of Fricadelles we forget eh :D .
The occasional electric heater does not cost that much: 2000 W on 4 hours a day for 3 months, it costs 130 € per year at the day rate. [2 kW * 4 hours * 30 days * 3 months * 0.18 cts / kwh]
On the other hand, the "background noise" (Internet box + VMC + fridge + phone chargers) consumes more than 100 W 24/24, or 157 € per year.
Depending on the financial means and the space available, there are 3 approaches:
- a solar kit of 500 € to put on the ground (fence, north wind screen) which will cover the consumption of the box and the fridge. It quickly pays for itself
- a more costly solar kit which allows you to run the dishwasher, the washing machine, the radiator, the oven which runs in the 2000 €. You need more space in the garden, it pays for itself more slowly, but it will allow the electric car that will arrive in a few years to be charged,
- the more expensive self-consumption kit with battery which almost eliminates the need for EDF from March to October. The kit with battery is difficult to make profitable. The batteries are still expensive.

To start and when you are not a specialist, it is best to start with one or 2 solar panels to be placed either against a south-facing wall (as a windshield, or vertically so as not to see the neighbor's barbecue anymore. :D ).
Then you can upgrade your installation. In any case, the price of solar equipment drops steadily.
Personally, I do not recommend putting the panels on the roof when you can put them on the ground.
