Maintenance and sustainability

Photovoltaic systems need a lot of maintenance. Since most of the time they are exposed to inclement weather, they need constant care. In case you feel any reduction in efficiency, call a technician immediately. To maintain yourself, clean the glass cover in parts (remove excess dust or pollution that accumulates) with a little water and a soft cloth, it is best to do it every two months. Verify that there are no loose or broken terminals.

One of the main concerns is the cost of solar panels. Regularly they are not cheap, in Mexico their price varies, you can find them from 3 thousand pesos up to 30 thousand approximately, depending on the size. But the truth is, the expense you will make is worth it since you will only pay once and the benefits will be reflected in your electricity bill, since the consumption is reduced by more than half, if you think it is a good refund for the initial investment.
