All about Belga Solar’s photovoltaic installations

A photovoltaic installation is an energy system that captures sunlight and converts it into electricity usingphotovoltaic solar panels. The system consists of several components: photovoltaic modules, an inverter, a roof-mounting structure, and sometimes a battery for storing the electricity produced. This type of installation is equally suited to homes and businesses.

Solar panels capture sunlight using silicon photovoltaic cells. These cells produce a direct electrical current. The inverter then transforms this current into alternating current, compatible with your electrical appliances. You can consume this electricity directly, or feed it into the grid.

A complete photovoltaic system consists of :

• Photovoltaic solar panels, mounted on your roof or on the ground.
• An inverter, which converts direct current into alternating current.
• A fastening structure adapted to your type of roof.
• A counter to measure production.
• Optional: a domestic battery for storing the electricity generated.

Yes, even without direct sunlight, your photovoltaic panels produce electricity thanks to diffuse light. Of course, production is lower than in full sun, but it's still significant. In Belgium, photovoltaic installations remain profitable, even with moderate sunshine.

Thermal solar panels heat water, while photovoltaic panels generate electricity.

The kWp (kilowatt-peak) measures the maximum output of your photovoltaic system under ideal conditions (optimum sunshine, temperature of 25°C). This unit is used to estimate the annual electricity production of your solar panels.

Solar panels require little maintenance. In general, the rain is enough to clean them. However, in dusty or agricultural areas, a manual cleaning once a year is recommended to maintain good performance. However, be sure to comply strictly with the warranty standards of your panels, or better still, call on our teams to use the appropriate equipment.

It is also advisable to regularly check operation of your inverter and production monitoring. At Belga Solar, we offer a follow-up service to guarantee the long-term performance of your installation.

Yes, photovoltaic panels Belga Solar photovoltaic panels are over 95% recyclable. In fact, the backsheet is fluorine-free and our frames are silicone-free. Solar glass, aluminum frames and silicon cells are recycled through specialized channels. As a Belgian manufacturer of solar panelsBelga Solar is actively involved in this recycling chain and complies with respects environmental standards in force. Working with a local supplier like Belga Solar also reduces the carbon footprint footprint transportation.

The price depends on several criteria:

• Total power required.
• The type of solar panels.
• The complexity of the installation (pitched roof, flat roof, shading, etc.).
• Complementary equipment such as inverters and batteries.
• Region (certain local subsidies influence the net price).

At Belga Solar, every project is unique. We draw up a personalized quotation that accurately reflects your needs.

Belga Solar solar panels are guaranteed for 25 years, with a very limited loss of yield (0.3 to 0.5% per year). In fact, many photovoltaic panels continue to produce electricity well beyond 30 years, with a slightly reduced yield.

The average lifespan of an inverter is around 10 to 15 years, about half the lifespan of solar panels. It is therefore common practice to replace the inverter once during the life of your photovoltaic system.

Yes, a photovoltaic system is profitable. With rising electricity prices and falling solar panel prices, the return on investment is rapid: often between 4 and 7 years. What's more, every kWh produced is a direct saving.

Yes, in Belgium, you can inject surplus electricity into the grid. You then receive compensation called an injection tariff. However, this remuneration is modest, which is why the most profitable solution remains maximum self-consumption: consuming your generated electricity directly.

Our Belga Solar installers will help you size your photovoltaic system to maximize self-consumption and savings.

By adapting your consumption to the hours of production (household appliances, heat pump) and adding a domestic battery to store the electricity produced during the day.

Yes, a house equipped with photovoltaic panels is more attractive on the real estate market. Future buyers appreciate the electricity savings and energy value of the property. In the event of resale, it's a winning investment.

Yes, companies often have large roofs, which means they can install high-power systems. What's more, their electricity consumption takes place during the day, when the solar panels produce the most power.

This guarantees a rapid return on investment, usually between 3 and 5 years, with direct savings from the very first year.

Yes, Belga Solar is the only Belgian solar panel manufacturer that also offers a complete service:

• Technical analysis and advice.
• Manufacturing and delivery of solar panels.
• Installation carried out by our in-house teams.
• Commissioning and certification.
• Long-term production monitoring.

Power output depends on your annual electricity consumption. In Belgium, the average residential installation is between 3 and 6 kWp, or around 8 to 16 solar panels. Our experts will advise you on the optimum power output, depending on your consumption, your habits and the surface area available on your roof.

Our solar panels are suitable for :

• Sloped roofs (tile, slate, steel).
• Flat roofs, with adapted structures.
• Ground installations on available land.

Yes, photovoltaic installations on flat roofs are common. Solar panels are installed on sloping structures to optimize exposure to sunlight. This type of installation is particularly common for industrial, commercial and agricultural buildings.

The ideal orientation for solar panels is due south, with a 30° to 35° inclination. It is in this configuration that electricity production is at its highest.

However, a south-east or south-west orientation is still very effective, with only 5 to 10% less production less. At Belga Solar, every project is designed to make the most of your roof.

Inverters and microinverters perform the same function: converting the direct current produced by your solar panels into alternating current for use in your home or business. The difference lies in the way they operate:

• Central inverter: a single device manages the entire photovoltaic system. It's less expensive and suitable for roofs without shading.
• Micro-inverters: each solar panel has its own micro-inverter, which optimizes production even if some of the panels are in the shade. Ideal for roofs with obstacles or mixed orientation.

At Belga Solar, we will guide you towards the best solution for your situation.

No, the domestic battery is optional. However, it is highly recommended for those wishing to increase their self-consumption and reduce their dependence on the grid. A battery stores electricity produced during the day for consumption in the evening or at night.

In most cases, no. Permits are sometimes required for ground-mounted installations or installations on listed buildings.

In Belgium, green certificates still exist, but their operation and attractiveness depend on the region:

• In Brussels, green certificates are still a major incentive for photovoltaic installations.
• In Wallonia, the green certificate system has been abolished for new residential installations.
• In Flanders, green certificates are no longer relevant, replaced by a compensation mechanism.

Our Belga Solar advisors will guide you according to your region and explain the most advantageous aid schemes for your project.

With Belga Solar, you benefit from :

• 25-year product warranty.
• 25-year production guarantee, with 84.8% minimum power output guaranteed.

Since power outlets are bidirectional, the Belga Solar station simply injects the solar electricity it produces into your home via a standard socket. This electricity directly powers your household appliances through your domestic electrical installation.
According to the physical principles of electricity, your appliances will always use solar power first, as it follows the shortest path. This process is entirely legal in Belgium and fully complies with current regulations. The Belga Solar station is C10/26 Synergrid certified, meaning it is officially authorized to be connected to a standard outlet in Belgium.
If you generate more electricity than your appliances consume, the surplus will be injected into the public grid. With a bidirectional or “smart” meter, you can measure the reinjected energy and, depending on your contract with your grid operator, benefit from compensation or payment for this reinjected electricity.
For more information on Belgian regulations regarding self-consumption and grid injection, please consult Synergrid’s guidelines and your local grid operator.

You can connect up to 2 panels per micro-inverter, plugged into the same outlet circuit, for a total power of 800 VA. This complies with European recommendations, which set a limit of 800W per household or electrical installation.
To ensure safety, we have deliberately chosen a micro-inverter limited to 800 VA, preventing any overload and ensuring compliance with current standards.

⚠️ Important precautions:

• Do not connect the station to a power strip to avoid overheating or fire risk.
• Ensure the station is connected to a socket circuit, not a dedicated circuit (such as oven, dishwasher, washing machine, or electric heating).
• Always comply with RGIE (General Regulations for Electrical Installations) standards when connecting the station.

By following these rules, you benefit from a safe installation that complies with European self-consumption standards.

Yes, it is compatible with all electricity meters: smart meters or electromechanical meters – it works in all cases.
You only need to check that your standard socket (16 Amps or more) is grounded and protected by a 300mA residual current circuit breaker (RCCB) located in the main electrical panel of your home. All compliant installations meet these safety requirements, but we still recommend verifying that your socket complies.

Yes, the Belga Solar station is fully compatible with three-phase installations.

The Belga Solar station automatically stops working to protect users, your installation, and grid technicians who may intervene on the line. This is a mandatory safety requirement under current regulations.

No, there is no risk. The station is designed to operate on a standard socket. The electricity produced will circulate safely and follow the natural flow of your home’s circuit.

Yes. The Belga Solar station is built with top-quality components, each of which complies with strict safety standards to ensure reliable and safe use.
In addition, our micro-inverter comes with a certificate of conformity that certifies its quality and safety. Your grid operator (DSO) may request this certificate when you declare your photovoltaic installation. Depending on your location, you will need to make this declaration with your local DSO (for example, Sibelga, Ores, RESA, etc.).
To help you with this process, Belga Solar provides a DSO declaration support guide, available on our website.

• Position the panels facing south in an area with as little shade as possible throughout the day.
• Adjust the inclination of your panels using the adjustable support according to the season. See installation guide.

Yes, but we recommend not exceeding 1kWc or 1kVA added to your existing system. If you exceed this limit, you may lose compensation benefits if you are eligible for them. Our SMART and PREMIUM stations remain below this threshold.

No. Cleaning is generally unnecessary. Only in cases of heavy dirt, and exceptionally, cleaning may be done with clean water (preferably demineralized or rainwater) and a soft, non-abrasive sponge.
Never use detergents, aggressive chemicals, abrasive sponges, or high-pressure cleaners, as they can damage the panels and void the warranty.

Thanks to its power and adjustable tilt, a PREMIUM Belga Solar station can produce between 800 and 1000 kWh per year depending on orientation. Based on your electricity purchase price, your station can be paid back in 3 to 5 years.

Our stations require no specific maintenance. Only in case of heavy dirt, we recommend cleaning the panels with a soft brush or sponge and rinsing with water (preferably demineralized or rainwater).
High-pressure cleaners, aggressive products, and abrasive sponges must not be used, as they can damage the panels and void the warranty.

Any surplus electricity is injected into the grid. With a bidirectional or smart meter, you can measure this reinjected energy and, depending on your grid operator contract, receive compensation or payment for it.

Although Plug & Play systems are authorized, their declaration with the DSO is not always required – it depends on your region.

• In Flanders, no declaration is needed if you are connected to Fluvius.
• In Wallonia and Brussels, a declaration is mandatory, even for small Plug & Play systems.

Even if these systems are generally not subject to RGIE inspection, power limits must be respected. Safety rules are also essential: use only fixed sockets (no power strips or extensions), connect the system to a non-dedicated circuit, and strictly follow instructions.
For details on procedures in your region, see our Belga Solar DSO declaration guide.

No permit is required as long as the system powers a building on the same property and meets one of the following conditions:
