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.
