Solar Panels

Solar panels are made up of individual solar cells, made of a special semiconductor silicon

material. When light hits a solar cell it displaces electrons, which flow down the wires as DC electricity. The DC electricity is then converted to AC electricity by the inverter, and can be used in your house, or sent to the electricity grid.

Yes, in so many ways! In addition to having a positive environmental impact,and investment in solar cells is economically advantageous. The payback period for solar cells is usually between 8-12 years depending on the conditions for your particular roof - that is, an investment with about 8-10% return on the investment.

Solar panel prices have heavily decreased in recent years as a result of the growing volume of solar panels produced around the world. A full solar panel system varies in price depending on the size of the system.

For a regular house, installation costs about 12 - 14 SEK /W (incl. VAT). Installing 30 solar panels (corresponding to a roof area of approx. 55 sqm) with a power of 360W per panel would cost 13 * 30 * 360 = 140 400 SEK.

Yes, in Sweden there is now a new tax reduction subsidy for solar panels at 15%, which covers costs of material and labour.

You can find more information on Skatteverket.

Solar panels vary slightly in size, but tend to be around 1m to 1.1m wide, and between 1.7 and 1.8m in length. Your solar consultant will make sure that you get the optimal solution for your roof.

Solar panels consist of a glass front, metal frame, solar cells which are made from a silicon semiconductor material, metal electrical wires, and a polymer back sheet. Svea Solar has carefully selected panels so the climate footprint will be as low as possible.

Yes, to ensure your safety when purchasing solar panels, we only work with large and well-known suppliers with the highest quality products. Should something against all presumption not work properly, all our products have long warranty periods. Read more about our warranties here https://sveasolar.com/warranty-legal/

Solar panels are sensitive to shadows because solar panels in a traditional plant are connected in series. There, the weakest link always restricts all other solar panels in that loop. To avoid this sensitivity, we can use optimized solar panels where the units are connected in parallel and thus do not limit each other. If you have shade on the roof, you can still get a good production with a well-dimensioned system.

Solar collectors convert the sun's energy into hot water, while solar panels convert the energy into electricity. We at Svea Solar have chosen to focus only on solar panels. A major advantage of solar panels is that they can be combined with other energy sources, such as geothermal heat. Similar solutions are more difficult with solar collectors.

Yes, at Svea Solar we install solar panels for business and residential associations. For more information visit our commercial site https://sveasolar.com/business/.

We connect our facilities to three-phase but could also connect it to one-phase facilities.
