How to choose the installation location for solar panels?
Choosing the place to install solar panels is an important decision that significantly affects the amount of energy produced by the system and its cost-effectiveness. In this article, we discuss key factors that should be taken into account when choosing a place to install solar panels.
1. Location and Orientation
The optimal location of the solar panels is one where they receive as much direct sunlight as possible. In Finland, this usually means a south-facing roof or other installation surface. The tilt angle of the panels should be around 30-45 degrees so that they get the best possible sunlight all year round.
2. Shades
Shading can significantly reduce the energy produced by solar panels. It is important to ensure that there are no large obstacles such as trees, buildings or other structures at the installation site that could shade the panels. The effect of shading can be assessed, for example, with a shading analysis.
3. The condition and load-bearing capacity of the roof
Before installing the solar panels, it is important to check the condition and load-bearing capacity of the roof. The roof must be strong enough to withstand the weight of the panels and the installation system. In addition, the roof must be in good condition so that it does not require major repairs in the near future.
4. Installation location size
The size of the solar panel installation site affects how many panels can be installed. In general, one solar panel takes up about 1.6 square meters of space. It is important to make sure that the installation site has enough space for the desired number of panels.
5. Electrical connections and inverter location
The electricity produced by the solar panels must be led to an inverter, which converts direct current into alternating current. The location of the inverter should be chosen in such a way that the electrical cables can be pulled along the shortest possible route, which reduces energy losses. In addition, the inverter should be protected from weather conditions and easily serviceable.
6. Permits and regulations
Before installing solar panels, it is important to find out about local permits and regulations. In some cases, installation may require a building permit or other official permits. It is also a good idea to check if there are any specific regulations in the area that may affect the installation.
7. Economic factors
Financial factors also influence the selection of the solar panel installation location. It is important to estimate the cost of installation and possible savings in energy costs. In addition, it is worth finding out whether there are subsidies or grants available that can facilitate the investment.
To sum up, it can be stated that the selection of the installation location for the solar panels requires careful planning and consideration of several factors. A correctly chosen installation location can significantly improve the amount of energy produced by solar panels and make the investment more profitable.
