There is already over 5,500 producers of solar energy in Caruna's network!
Did you notice new solar panels on your neighbour’s roof last summer? Today, generating solar power for your own use is easy and financially sensible. When planned carefully for your needs, a solar energy system can generate savings of up to three times its initial cost during its technical service life. If your roof is bathed in sunshine and you are considering fitting it with solar panels, we can help you get started.
Most solar energy systems are provided as a turnkey solution. A professional company will design a system that best suits your needs, install it so that it is ready to use, guide you through the commissioning of the system, and take care of all the necessary licences for you!

Solar panels on my roof?
Is there enough Sun here in the North?
- A solar power system installed in Southern Finland generates just as much electricity as one installed in northern parts of Germany. And in other parts of Finland, the amount of electricity generated is only slightly lower.
How long does it take for the system to pay for itself?
- The average payback period for solar panels is 10 to 15 years. The solar panels have a 25-year guarantee, but their actual lifecycle is a lot longer; you will generally get at least ten years of free usage. The investment is at least as good as an investment in a new kitchen or a car.
How do I know how many panels I need?
- In terms of viability, it is essential to try and match the amount of power generated with the use of electricity in your home as accurately as possible. An expert will be able to design a system with the ideal number of solar panels for your needs.
Is it worthwhile ordering the panels even though I’m moving soon?
- A solar energy system may well improve the value of your property when you sell it; solar energy has a good reputation.
Still not convinced?
My roof isn’t facing south – and that’s the direction from which the sun shines. And there are trees overshadowing my roof too.
- If your roof isn’t facing south, you can install one half of the panels on the east slope and the other half on the west slope of your roof. Your use of electricity at home may also peak during the first and last hours of sunshine every day. Even a small patch of shadow on a solar panel will reduce its energy output significantly. Would it be possible to fell the trees and use them for firewood?
What about during winter? There was at least half a metre of snow on the roof last winter.
- In the darkest months of the year, solar panels can only generate power for short periods each day. Therefore, snow cover is not an issue. The panels should be strong enough to take the weight of snow – remember to ask your solar panel supplier. Did you know that the efficiency of the panels is actually at its highest when it’s cold?
What can I use solar energy for?
- The solar energy your panels generate will automatically be used in your home. Depending on the equipment in your home, you can use solar energy for heating your home and domestic water, cooling and cold storage, and lighting. Even for recharging your electric vehicle in the future. Any surplus amount of solar energy is automatically transferred to Caruna’s distribution network, and you can sell it to your electricity vendor.
Do I need a licence to install the panels?
- Some municipalities may require you to obtain planning permission to install solar panels. Please check with your local construction supervisory authorities to find out if this is the case. As soon as the electrician has submitted the required information to Caruna, we will provide you with the commissioning permit as quickly as possible. The electrician will know what to do.
Do the panels produce energy if there is a power cut?
- To ensure electrical safety, a solar energy system (without storage batteries) will be automatically switched off during a power cut, and back on when the power cut is over. In most cases, power supply interruptions occur in windy, rainy, and dark conditions when the sun does not shine, and the panels would not be generating any power.
OK, I’m convinced! Who should I buy from? Can I trust solar energy salespeople?
- There are many solar panel suppliers and it's a good idea to compare different companies! Motiva's website Solar energy for your home (in Finnish) is a great place to start.
