In Spain, more than 200,000 homes have self-consumption solar panels. They are mainly single-family and residential houses outside of large urban centers.
The increase in electricity bills due to the inflation of the war in Ukraine, public aid for the installation of plates in homes with Next Generation funds and also the development of the electric car have filled the roofs with solar equipment.
“Self-consumption will continue the growing trend of this year 2023, you just have to observe the progression it has experienced after the elimination of the Sun Tax in 2018: in 2019 it obtained 459 MW of power, 596 MW in 2020, 1,203 MW in 2021 and 2,507 GW in 2022”, explains the general director of the Spanish Photovoltaic Union, José Donoso.
According to a Unef report, once the milestone of 5GW of installed power for self-consumption at the national level has been passed, which also includes the industrial sector, Spain is advancing at cruising speed in meeting the objectives set out in the sheet self-consumption route published by the Ministry of Ecological Transition and Demographic Challenge.
This commitment to solar self-consumption seems logical, and more so in a country like Spain, also taking into account the United Nations 2030 Goals in terms of CO2 reduction in mobility.
The proliferation of solar panel equipment, which in some cases will save up to 45% on the monthly electricity bill, also has a B side: its maintenance.
It is not that it is expensive for the consumer, but due to the position of the equipment in the upper part of the houses, it can be difficult to clean the solar panels. Dirt can reduce the performance of the panels.
Below we highlight several key points to keep solar panels in optimal performance:
