Estimating photovoltaic production with PVGIS has several significant advantages for people considering investing in solar panels or looking to do so. optimize their existing solar installations:

1. Accuracy of estimates:

PVGIS uses precise weather data and location-specific information to calculate photovoltaic production. This allows for much more precise estimates than estimates based on general approximations

2. Personalization:

PVGIS allows users to provide detailed information about their installation, such as type of solar panels, installed power, orientation, tilt, etc. These specific data make it possible to obtain a personalized estimate of production.

3. Location comparison:

You can use PVGIS to compare different locations to determine which is best suited for your location. à installation of solar panels. This allows you to choose the best location to maximize solar energy production.

4. Help with decision making:

PVGIS provides clear and understandable data on expected photovoltaic production, helping individuals to plan their projects. make informed decisions about their solar energy investments. You can thus estimate the profitability of your business. potential of your installation.

5. Optimization of efficiency :

By providing information on the optimal tilt and azimuth, PVGIS can help to improve visibility. optimize the design of your solar installation for maximum production. This helps you get the most out of your investment.

6. Availability free online:

PVGIS is a free online tool, accessible anywhere. all, making it easily accessible for individuals who wish to carry out estimates without having to worry about it. incur additional costs.

7. Taking into account geographical variations:

PVGIS covers a large part of the globe and can be used anywhere. in many parts of the world, making it useful for people living in diverse locations.

8. Performance monitoring:

Once your solar installation is operational, you can compare actual results with the estimates provided by PVGIS to evaluate the performance of your system and identify potential problems. deviations.

9. Reduction of financial risks:

By obtaining an accurate estimate of expected photovoltaic production, you can better plan your investment, thus avoiding taking unnecessary financial risks.

10. Contribution to the energy transition:

By encouraging the adoption of solar energy, PVGIS contributes to the adoption of solar energy. the transition to cleaner and renewable energy sources, which has a positive impact on the environment.

PVGIS remains the most advanced tool for anticipating the performance of a photovoltaic system. It is important to remember that PVGIS operates in a theoretical environment, and that the actual power of a photovoltaic system can vary considerably once it is installed. and in operation.
