Solar power - unlimited source of energy
Solar power is the key to a clean energy future. Every day, the sun gives off far more energy than we need to power everything on earth. That’s why we’re investing heavily in solar plants and why we are now offering solar kits to our customers in Finland, Norway and Sweden.
Solar panels produce electricity by transforming the continuous flow of energy from the sun to electricity.
No harmful emissions are released into the air when electricity is produced by solar panels.
Low operating costs
The photovoltaic process that transforms sunlight into electricity doesn’t require any fuel and has no variable costs.

Limitless solar energy
The sun provides more than enough energy to meet the whole world’s energy needs, and unlike fossil fuels, it won’t run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
Solar energy - a clean source
No greenhouse gas emissions are released into the atmosphere when you use solar panels to create electricity. And because the sun provides more energy than we’ll ever need, electricity from solar power is a very important energy source in the move to clean energy production.
No fuel to burn
After solar panels have been installed, operational costs are quite low compared to other forms of power generation. Fuel isn’t required, and this means that solar power can create large amounts of electricity without the uncertainty and expense of securing a fuel supply.
FAQ – Solar power
What is solar power?
A power generation method that converts energy from the sun into electricity. It uses solar panels that are often arranged on a building or concentrated in solar farms to facilitate a reaction that converts sun’s light radiation into electricity.
How do solar panels work?
Photovoltaic cells in a solar panel turn sunlight into direct current electricity (DC). Then, an inverter converts the DC electricity into alternating current electricity (AC) and once this process has taken place, the electricity is used, fed into the grid or stored in a battery.
Are solar panels expensive?
The cost depends on how many panels are installed and how/where they are installed, but generally solar power is becoming more affordable every year. Solar power is the future key production method in the move to clean energy, and as economies of scale drives prices down, its importance will only increase.
What are the advantages of solar power?
The main advantage is that it is a renewable, clean source of electricity. Solar power is also scalable. This means that it can be deployed on an industrial scale or it can be used to power a single household. When it’s used on a small scale, extra electricity can be stored in a battery or fed back into the electricity grid. Overall, the sun gives off far more energy than we’ll ever need. The only limitation is our ability to convert it to electricity in a cost-effective way.
Solar power and the environment
As a renewable CO2-free power source, the environmental impact of solar power is significantly smaller than other power generation methods. The impact is mainly related to the production and supply of the special materials and metals that are required to produce solar panels. The location and the water used to clean the solar panels also affect the environment. We are working hard to find alternative ways to clean our solar panels.
