How much electricity does solar panels produce?05.10.2019
Have you ever thought about how much energy solar panels actually produce? At SVEA Solar, we straighten out any question marks about how much electricity solar cells can produce, living in the Swedish climate. Read on and see if solar panels are a match for you!
How much electricity does solar panels produce per year?
The production of solar energy is affected by a number of different factors. Therefore, it is difficult to answer exactly how much electricity solar panels produce over a certain period of time. As Sweden has a changing climate, with widely different seasons, it also affects the conditions for producing solar energy. But there are different ways to estimate how much energy you can expect!
To calculate the expected effect of the solar panels, we at SVEA Solar usually talk about two things:
- The efficiency of the solar panels
- The amount of electricity produced (kWh) per installed kW.
SVEA Solar's solar panels have an efficiency of about 17-20%, which means that about 17-20% of the solar energy produced by the solar cells is converted into electricity.
When it comes to "kWh per installed kW", we at SVEA Solar usually say that an installed kW produces about 800 - 1100 kWh / kW per year. This means that if you have installed solar panels that have a peak power of 2 kWh, your solar panels can produce around 1600 - 2200 kWh solar per year.
How much electricity does solar panels produce per month on average?
As explained above, it is difficult to estimate an average of how much electricity your solar panels produce per month, as production differs from month to month. In the summer we usually produce more than we manage to use, while in the winter we need to compensate by buying more. In addition to the hours of sun, there are other factors that affect how much electricity the solar panels produce.
Some common factors that affect how much electricity solar panels can produce are:
- The amount of sun where you live
- Possible shade on the solar panels from trees, buildings etc.
- What direction your solar panels are facing
- The angle of your solar panels
- If there is any snow on the solar panels
- If there is any dirt on the solar panels
- The efficiency of the solar cells
In other words, how much electricity your solar cells produce depends on what conditions you have!
