What is the difference between solar electricity and solar heat?
Solar electricity generates electricity in the form of direct current that is then converted to alternating current. Solar heat generates heat by heating up water.
Does the sun shine enough in Sweden?
The potential for solar energy is good in Sweden, with the country enjoying almost as many hours of sunshine as central Europe.
Does solar energy also work during the winter?
During the winter months, there are fewer hours of sunlight and the sun sits low in the sky, so energy generation levels are very low or zero if there is snow on the roof. Generation levels are highest between March and October.
Do I need planning permission to install a solar energy system?
The rules vary from municipality to municipality, so check with your local authority before undertaking an installation.
Where can members of the general public buy your products?
See our dealers.
How much energy do solar cells generate in Sweden?
Depending on where in Sweden you are, you can expect to get 800-1100 kWh/kW and year. In the Stockholm region, solar cells will typically generate 900-1000 kWh/kW and year.
Can you store electricity that you don’t use?
No, the solar cell system is not normally connected to a battery and therefore there is no facility to store electricity. Surplus electricity is fed into the mains electricity grid and can be sold to your electricity provider, who will sell that energy on to other electricity customers.
If you have access to the mains electricity grid, battery solutions are not yet justifiable for the normal household, although new solutions are reaching the market all the time.
What happens when panels break or can no longer be used?
Broken and dead solar cells will be taken back by SolTech Energy and sent for recycling.
How does a solar cell work?
A solar cell is a thin sliver or film of a semiconductor material that is structure so that, when exposed to light, it generates electrical current between the front side and the rear side.
Can I walk on the panels?
You can, but you should avoid doing so.
What is required to connect a solar cell system to the mains electricity grid?
You must notify your electricity supplier that you intend fitting a solar cell installation on your building. If you want to sell your solar electricity, you must contact an electricity supplier that is willing to buy the power you generate and then draw up an agreement with them.
Can I receive a subsidy for solar cells?
Up to and including 2016, government grants are available to cover the cost of installing solar cells, including the hardware and labour. As of 1 January 2015, grants of 30 % are available for companies and 20 % for everybody else. Grants will remain available for as long as the pot of money set aside to support works of this nature lasts. Grant applications are processed by the County Administrative Board, which also makes the final award decision. For more information, contact your local County Administrative Board.
Am I eligible for an ROT rebate on a solar cell installation?
You will receive an ROT rebate for the labour costs associated with the installation of your solar system provided that you have a sufficient ROT rebate amount available to you and that your solar cell system is installed and paid for in the same year. However, if you receive a government grant for your installation, you will not be eligible for an ROT rebate.
How long will the panels last?
Solar cells have a life expectancy of over 30 years.
Can I connect solar cells myself?
Connection on the roof can be done by someone who is good with their hands as no formal qualifications are required. Installation inside the building must be carried out by a qualified electrician.
How much maintenance work should I expect?
Very little maintenance is required as there are few moving parts that may give you problems.
SolTech ShingEl is a unique building integrated solar panel that provides the same construction dimensions and specifications as Benders tile Carisma.
It is in itself a part of the building envelope on the property, without the need for additional accessories. Let your roof generate energy without having to compromise or compromising on functionality or aesthetics.

Our solutions provide architects best possible conditions to be creative in new construction but also for the preservation of the character of the older house, whatever roof type.
How much does the roof installation weigh?
The installation weighs approx. 18 kg/m².
Which level of transparency should I choose?
As the need for shade is normally higher in a roof than in a frontage, a lower level of transparency is usually preferable in roof installations, whilst a higher level of transparency is normally required for frontages in order to give a better view.
How is SolTech ST installed?
