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.
