The principle of photovoltaic self-consumption is simple: solar panels, installed on your roof or on the ground, capture solar radiation and transform it into direct current. This direct current is then converted into alternating current, usable in your home, thanks to an inverter. The electricity produced is then used directly by your electrical appliances and your heating system.
When your solar panels produce electricity and you use it simultaneously, you are in a self-consumption situation. For example, if your washing machine is running while your panels are producing electricity, the energy used by the washing machine comes directly from your solar panels. The higher your self-consumption rate, the more you reduce your dependence on the power grid and save on electricity bills.
When your solar panels produce more electricity than you consume, the surplus is fed into the public power grid. In Switzerland, these kWh are generally paid for by your distribution grid operator. The sale of surplus from solar production therefore generates additional income for your household. This remuneration, although lower than the price of the electricity you buy from the grid, contributes to the profitability of your solar panel installation in Switzerland.
To maximise your solar self-consumption in Switzerland, you can install a storage battery. The battery stores the excess electricity produced during the day so that you can use it in the evening or on days with low sunshine. Thanks to the battery, you can increase your self-consumption rate to 70% or more, further reducing your energy bills and your dependence on the grid.
In Switzerland, several types of subsidies and financial aids exist to encourage the installation of photovoltaic panels. These aids vary according to the canton and municipality, so it is important to check with local authorities to find out the precise arrangements applicable to your situation.
Many cantons and municipalities offer financial contributions for the installation of photovoltaic panels. The amount and conditions for granting these subsidies vary from one region to another.
For installations over 10 kW, the surplus electricity fed into the grid is bought back at cost price by the grid operator. This mechanism allows the energy produced but not consumed to be valued.
Some cantons provide tax breaks for owners who invest in photovoltaic installations.
Some banks and financial institutions offer preferential-rate loans to finance photovoltaic installations.
