Annual electricity consumption:
Your annual electricity consumption is a very important factor. Please select the sizes of your household or look up your precise annual consumption from your electricity bill.
The electricity price:
On your electricity bill you will also find the electricity price your supplier charges per kilowatt hour. For the given example we are using the average electricity price in the United Kingdom.
The electricity consumption:
Workdays or on the weekend?
Please enter your address with postcode, street and house number - this allows us to link your site to the amount of solar resource in your region.
1 Roof size:
Please enter the length and the width of your roof to calculate the roof size.
In case you do not know the dimensions of your roof, walk along the wall of the building in 1-metre steps and count the steps. Do this once lengthwise and crosswise per direction.
If your roof faces several directions, only determine length and width of one side of the roof.
Do you want to set up your solar system in several directions? Please contact our installation partner for more detailed planning.
2 Roof tilt
How much is your roof tilted? If you are not sure, try it. What does your roof look like?
3 Which direction does your roof face?
For optimum solar radiation your roof should face south and/or east/west. Please mind this when selecting your site.
We have calculated the covered roof area of your site and the direction of your roof towards the sun during the course of the day using your data.
How do I find the right solar module for my site?
Q CELLS develops and produces poly-crystalline and mono-crystalline solar modules for various applications. For your roof-top system we offer the solar module series Q.PEAK and Q.PLUS. The modules of the Q.PLUS family offer excellent solar power yields at best price-performance ratio for your roof. The solar modules of the Q.PEAK family are characterised by maximum performance on small roof areas and an appealing black design.
Based on your energy consumption the Q CELLS solar calculator determines the optimum size of your solar system. This optimises your system for self-consumption. The energy generated by the system is fed into your home grid and directly consumed by electric appliances such as washing machine, tumble dryer and many others. This saves you money because you do not need to take this energy from the grid. Instead you make use of the electricity you generated on your roof.
This provides you with the best saving potentials.
Do you still want to feed more electricity into the grid? Are you interested in a storage solution? Or do you want to already now cover higher electricity needs in the future, for an electric car for example? Your Q CELLS installer will be glad to consult you individually in detail. Please let us know your wishes in the next step.
After receiving your contact data, we will immediately process your inquiry. A Q CELLS partner will contact you. We will send you a copy of your personal calculation by e-mail after having received your inquiry.
