Valls is the capital of the Alt Camp and is surrounded by fields and farms. In a setting like this, agricultural dust, dry summers and birds build up easily on solar panels, and rain doesn't always clean them. If you have a solar installation on a home, a country house, a warehouse or a farm in the area, cleaning at the right time gives you output back.

How much your installation should produce in Valls

According to PVGIS, the European Commission's official tool, a 1 kWp installation facing south at the optimal tilt (38°) with 14% system losses produces about 1,580 kWh a year in Valls. The best month is July, with about 158 kWh per kWp, and the weakest is November, with about 104 kWh [1].

If your installation clearly produces less in a clear month, dirt may be one of the causes. We explain it in more detail in our production guide.
