1. This is what you should consider if you want to use your patio roof for solar power

Often the patio roof is the only option for installing a solar system, as many houses do not allow for such installation. But there are also a few things to consider when it comes to patio roofs.

Due to the lower slope than on house roofs, dirt and snow deposits are more likely to remain on patio roofs and solar panels. This results in a higher Cleaning effortFlat roofs also generate less energy than those with steep slopes. Orientation of the roof to the sun should be taken into account because this has a significant impact on how much electricity can be generated. It must also be noted that patio roofs cannot bear too much weight, which is why they are a sturdy product should have.

Not suitable for a photovoltaic system are:

• Awnings
• Pavilions
• Sun sail

Because they cannot bear the weight.

1.1. These are the advantages of a photovoltaic system on the terrace roof

A small PV system cannot supply the entire household with electricity. Overall, however, a patio roof with a solar system can be extremely worthwhile if you consider the environmental aspect as well as the economic one. The solar modules on the patio roof also offer other advantages.

With a solar system on your patio roof:

• generate sustainable electricity
• you can install a charging station for electric vehicles
• make sensible use of otherwise unused space
• save on expensive electricity prices and become more independent from them
• You do not need an additional awning or sun sail due to the sun protection provided by solar modules

A solar system on your patio roof combines utility with practicality. This way you can unused area not waste it, but use it to generate electricity. This way you also contribute to protecting our environment. Unlike conventional energy sources, renewable energy does not cause any emissions during use and therefore has a positive environmental balance.

In addition, you can combine two further advantages. The solar module offers protection from the sun and thus ensures a pleasantly cool and shady place to stay under the patio roof in summer, while on the roof the incoming sunlight is converted into electrical current. If you economic, ecological and practical advantages together, it quickly becomes apparent that a PV system is also ideal for patio roofs.

Photovoltaic systems on the terrace roof offer these properties:

• They are environmentally friendly
• They are durable
• They are robust
• They are practical

2. Which solar modules are best suited for a patio roof?

The typical PV systems, which are usually available in blue, are translucent, but they darken the terrace in any case. But that is exactly what the majority want, because then there are no additional costs for black-out awnings and it is cooler on the terrace in summer.

Solar modules made of glass on the front and back are an alternative for those who do not want darkening. Glass-glass modules The solar cell string is located between two clear glass plates. Embedding films on both sides, which are also transparent, provide additional protection. A major advantage of Glass-glass modules are also extremely durable and are particularly resistant to various weather conditions. However, they are often heavier and more expensive than conventional solar modules. See also: https://www.sciencedirect.com/science/article/abs/pii/S002627141500027X

Another form of solar system is Glass-foil modules These have milky or medium-transparent back films, which create partial shade on the terrace. Compared to modules made entirely of glass, they have the advantage of being lighter and quickly paying for themselves economically. But the film models also have their weaknesses. They are not as durable and have a lower yield. After 30 years, for example, their yield is around 30 percent higher than that of pure glass models.

2.1. Solar system without terrace roof

If you decide against a solar system for your patio roof, there are Alternativesto generate solar energy. This allows PV systems can also be installed on the roof of garages or carports if they are correctly aligned. If the direction of a house facade allows it, solar modules can even be installed there. The development of such Solar systems in mini format As with regular PV systems, developments are ongoing, so it may be worth staying informed and up to date. For example, developments could mean that you may be able to make a financial gain due to government subsidies while protecting the environment.
