solar battery

How to choose a solar battery for your photovoltaic installation in 2022?

After having approached the installation of photovoltaic panels, it seems logical to us to cover the subject of batteries, essential for the realization of an autonomous solar installation or to increase its solar self-consumption. Indeed, if you have opted for an off-grid installation therefore not connected to the electricity grid, the electricity produced by your solar panels will have to […]


Install photovoltaic panels in 2022? An interesting solution towards energy independence

The transition to solar energy production in France should accelerate for companies and public buildings thanks to the solar plan in 2022. This energy production involves the installation of photovoltaic panels allowing the production of solar electric energy carbon-free. But what about individuals? With the collapse of solar photovoltaic prices, divided by […]
