A plugin solar kit produces solar energy for self consumption at home. The energy it produces is used directly by your household appliances. This avoids you having to buy that energy from your power company, lowering your power bills.
Your savings are therefore determined by
how much energy your kit produces
how much you pay your power company per kWh, with all extra costs and taxes included
For example, if your kit produces 1.600 kWh per year and you pay €0,25/kWh to your power company, you save €400 per year (1.600 kWh x €0,25/kWh = €400). You can calculate how much you can save at your home address with our Savings Calculator or check the European Commission’s PV GIS.
How much the savings are on your overall electricity bill depends on how much you consume in total. If your yearly consumption is 1.500 kWh, then you’ll save over 100% of your power consumption. If you use 5.000 kWh, it will be just 32%. The average household in Southern Europe consumes about 3.200 kWh/year, where a kit can save half of it.
In any case, some savings are better than no savings at all. Every kWh you can produce yourself is a kWh you don’t have to buy from the grid, saving you money every day.
