What risks should you consider if you want to install solar panels yourself?

The installation cost of solar systems is significant, requiring an investment of several million HUF. The total amount depends on various factors, such as the size and type of the system. Hybrid and off-grid solutions generally belong to a higher price range, while grid-tied systems are becoming less advantageous due to the abolition of the net metering system. In general, one should expect at least 1.5-2 million HUF in expenses when installing a new system. However, various state support programs, such as the Solar Energy Plus Program, can help reduce costs through non-repayable grants.

Solar systems not only play a role in minimizing electricity bills but also contribute to energy independence in the long term. The current economic and environmental challenges increasingly highlight the importance of ensuring our own energy supply at home, for example, through hybrid or off-grid systems.

Dangers of DIY Solar System Installation:

DIY installation is not recommended because electricity is dangerous, and a poorly installed system can not only be ineffective but also pose a fire hazard.

Common Mistakes During Solar System Installation:

A solar system consists of several components, and there are many points where mistakes can occur during installation. Here are the most common issues:

1. Incorrect Tilt Angle and Orientation

   The performance of solar panels is significantly influenced by the correct tilt angle and orientation. For optimal results, panels should be installed at a 40-degree tilt facing south. If this is not feasible, a tilt angle between 30-50 degrees and an orientation towards southeast or southwest can still provide up to 90% efficiency.

   
   

2. Weak Mounting Structure

   The mounting structure plays a crucial role, as it secures the panels. It should be made of stainless steel or other weather-resistant materials to withstand rain, snow, and wind.

   
   

3. Improper Installation

   Installation requires not only electrical knowledge but also the proper integration of components. A poorly assembled system can lead to performance issues and even be dangerous. Therefore, always check the contractor's references and expertise.

   
   

4. Low-Quality Components

   It is not worth cutting corners when it comes to solar systems. A low-quality inverter or panel can result in additional costs in the long run, so always choose products from reliable manufacturers.

   
   

5. Missing Permits

   Installing a solar system requires obtaining various permits and coordinating with the utility company. Many contractors handle these tasks, which can greatly simplify the process. If you also want to apply for funding, such as through the Solar Energy Plus Program, it is worth looking for a contractor who can assist with this as well.

Considering the above, a well-designed solar system can be a long-term profitable and secure investment.
