Is a solar PV installation🏡☀️ profitable in winter❄️?
👉 Absolutely, YES! ✅
In this post we explain how “winter” ❄️ and “solar panels” are related☀️ , what happens when it rains 🌧️or snows🌨️ and what the best maintenance is ⛏️for your installation during the coldest months.
How do low temperatures affect my solar PV installation?🥶
  • The efficiency of a solar PV installation depends on sunlight not on heat, so cold weather does not affect energy production.
  • In fact, low temperatures are better than high ones, since temperatures above 35 ºC reduce the efficiency of solar PV production.
  • It is true that in winter, since there are fewer hours of sunlight, there are also fewer hours of energy production.
  • One way to make up for this is to install a battery system to store the energy produced during the day and use it during the hours without sun.
How can rain and snow affect my installation?💧☔❄️🌨️

  • When it rains, sunlight becomes diffuse and indirect, but the panels still keep producing solar energy.
  • Rain can help wash away dirt particles that build up on the solar panels.
  • In the case of snow, just as when it rains, sunlight is still present indirectly, so energy production does not stop.
  • What’s more, both the tilt of the panels and the material they are made of help the snow slide off, so it doesn’t build up on the roof.
Does the installation need more maintenance in winter? ⛏️🔨

  • Maintaining a solar PV installation in winter is similar to the rest of the year. However, leaves, snow, dust, etc. can build up on the panels during this season. In any case, it all depends on where the installation is and on the weather.
  • It is very important to hire a good maintenance service to keep yoursolar PV installation at full performance and ensure maximum production and energy efficiency.
