It is a fact that the number of photovoltaic systems in homes and businesses is growing all the time. You look up and there are more and more roofs with solar panels. So much that, according to data from the Unión Española de Fotovoltaica (UNEF), photovoltaic self-consumption in Spain grew by more than 100% in 2021 compared to the previous year. And this trend continues to rise, because in the first quarter of this year the installation of self-consumption panels has increased by 29%.

Why has interest in photovoltaic self-consumption increased?

Although the trend has been upward for several years, it is expected to grow even more, with the number of self-consumption installations increasing by a factor of 5 by 2030.

This situation is especially motivated by the following causes:

  • Increased EU subsidies, facilities and funds for installations. The progressive elimination of administrative barriers (remember that until 2018 there was a sun tax) and the increase in local incentives have increased the commitment to this technology.

  • The war in Ukraine. The conflict between Russia and Ukraine has highlighted the importance of not depending on Russia for energy.

  • Rising electricity prices. The price per kWh has reached historic highs in recent months. This has promoted photovoltaic installations which, at the current price of electricity, pay for themselves in half the time they used to.

  • Increased environmental awareness. The effects of climate change are becoming increasingly evident and many people are beginning to advocate sustainable and clean energies to combat this situation.

Why more people are installing solar panels

Having said that, what is the reason for people to install solar panels on their homes or businesses?

  • Savings on electricity bills. With solar panels the savings are, on average, between 30 and 80% on the electricity bill. And at today’s prices, that’s a great relief.

  • The panels pay for themselves in about 5 years. Precisely because of the rise in electricity prices, the panels are amortised faster than before, and right now they do it on average in about 5 years.

  • Panels for 25 years… or more. Until now, the average lifespan of a panel has been around 25 years, but with the latest advances and improvements in materials, we can extend its use up to 40 years.

  • It helps the environment and the fight against climate change. Solar energy is a clean, renewable energy and reduces CO2 emissions into the atmosphere, making it a great ally in the fight against climate change.

  • It avoids energy dependence. Solar energy avoids energy dependence on conflictive countries such as Russia.
  • It is a very easy and fast process. Thanks to the digitalisation of all the processes in the photovoltaic value chain, in just a few minutes the user knows the price he is going to pay and the company is able to design the installation from the office.

An example of this are companies such as Solar360 or Plenitude, which have simulators that give you the result instantly.
