Solar photovoltaic

Photovoltaic modules installed on a sloping roof or facade occupy an area of approximately 8 m2/kWp.

Photovoltaic modules installed on the ground or on a flat surface occupy an area of approximately 20 m2/kWp, avoiding shading between the rows of modules.

The design of a photovoltaic system, from the public operator’s network to the photovoltaic modules, requires careful planning and compliance with local regulations.

Here is a general guide you can follow: Read more

Location Analysis:

– Evaluate the position and orientation of the roof or area intended for the system.
– Determine the average solar radiation in your area.

Calculation of the Necessary Power:

– Determine the average daily energy consumption of your building.
– Choose the power of the photovoltaic system based on consumption and local solar radiation. For a 6 kW inverter, you may need to install around 8-10 kWp of photovoltaic panels, considering efficiency losses.

General diagram of the system:

– Connects the system to the public operator’s network through a bidirectional meter.
– Place inverters and electronic components in a safe and accessible place.

Choice of Photovoltaic Modules:

– Choose photovoltaic modules with suitable characteristics, such as efficiency, durability and warranty.
– Arrange modules in optimized strings to maximize energy production.

Inverter sizing:

– Select an inverter of at least 6 kW to adapt to the power of the system.
– Consider using inverters with monitoring technology for more efficient management.

Security and Monitoring Components:

– Include protective devices against overvoltages, short circuits and fast interrupting devices.
– Add monitoring systems to check plant performance.

Electrical Design:

– Develop a detailed electrical diagram showing the connection between the modules, the inverters, and the public grid.
– Make sure you comply with all local regulations and laws regarding photovoltaic systems.

Authorizations and Administrative Practices:

– Obtain the necessary administrative permissions and approvals from local authorities.
– Make sure you comply with all regulations on connecting systems to the grid.

Installation and Maintenance:

– Install the system following the design specifications.
– Schedule periodic checks and maintenance to ensure optimal performance.

Performance Monitoring:

– Use monitoring systems to track energy production and identify any problems.

Remember that this is just a general approach. Always consult an industry professional and be sure to follow local regulations and guidelines for the design and installation of photovoltaic systems.
