Photovoltaic Panel Installers à Liège

Photovoltaic and solar panels

How does a photovoltaic panel work? The functioning of a photovoltaic panel depends on two main criteria: the inclination and the orientation of your roof. A photovoltaic panel includes two important elements. Firstly, the presence of sunlight capturing a photovoltaic panel will create photons. These photons will then reach the photovoltaic cells. Secondly, the production of solar energy will be done thanks to the silicon, which is present in each photovoltaic cell. This type of electrons will allow all the solar energy to be transformed into electrical energy in order to power your home. This system also makes it possible to group together all of this solar energy that has become electrical, manufactured in each cell present in a photovoltaic panel. Why install photovoltaic panels? There are many advantages to investing in and installing photovoltaic panels in Liege. The main advantage, which is really interesting, is to produce your own energy, renewable and recyclable, to power your home. CO2 emissions are literally reduced: solar energy from solar panels is a good idea if you want to opt for environmentally friendly energy production. Photovoltaic panels have also gained in quality in recent years, with an increasingly affordable price-performance ratio. Even if the installation of photovoltaic panels in Liege represents a significant investment, it should be noted that the return on investment is interesting, ranging from 5 to 10 years. This can, in the long term, allow you to make significant savings, and reduce the final cost of your energy bills. Another advantage of installing photovoltaic panels is the ease of installation, which you can do yourself or by a certified professional. In addition, photovoltaic panels require little regular maintenance. However, a cleaning of the photovoltaic panels every 3 to 4 years is strongly recommended to preserve their life span. The lifespan of photovoltaic panels is estimated at between 25 and 35 years, depending on their energy yield. How do I find a photovoltaic panel installer in Liege? To find a photovoltaic panel installer in Liege, various professionals offer photovoltaic panels according to your installation project and your needs according to your annual energy consumption. They offer, for example, competent expertise and can guide you in the choice of photovoltaic panels. Do not hesitate to ask several professionals specialized in the installation of photovoltaic panels in Liege and to compare the various estimates to make a choice according to your budget. What type of photovoltaic panels should I choose in Liege? There are two types of photovoltaic panels, but the most common is crystalline silicon photovoltaic panels. This type of photovoltaic panels gives a very interesting energy yield: the energy production is therefore more powerful and the power supply of your house will be improved. If you have a flat roof, for example, photovoltaic panels with thin layers are preferred. However, the energy yield is much less powerful than photovoltaic panels. Photovoltaic panels are available in two materials on the market. Firstly, monocrystalline photovoltaic panels, which are black in color. They have a longer lifespan, up to 30-35 years, and the energy yield is more powerful, especially in freezing temperatures. Its price, estimated at an average of 250€ excluding VAT per panel, is particularly recommended if you have a south-facing roof. The manufacture of energy is, on the other hand, more generating in the production of CO2. Secondly, polycrystalline photovoltaic panels, available in blue. In addition to a more regular energy production and more affordable from a financial point of view, costing on average 220€ per panel, excluding VAT, it generates little CO2. However, its lifespan is shorter than that of monocrystalline photovoltaic panels. How to calculate the profitability of photovoltaic panels? The profitability of photovoltaic panels is based on several criteria, according to the Walloon Region and APERe: the annual energy consumption and the price of electricity per kWh are two of the main points for this calculation. Also consider the number of photovoltaic panels on your roof, as well as the orientation of the roof. You can also include the price of the installation, as well as a loan dedicated to the purchase of photovoltaic panels and its loan rate. In the case of a photovoltaic panel installation in Liege, your annual energy consumption is estimated at 5000 kWh per year, with an estimated electricity price of 0.27€ per kWh. You have opted, for example, for an installation of 6 photovoltaic panels on your roof, inclined at 50° and oriented at 30°, costing 6 000€. According to this simulation example, you can make about 770€ per year on your annual electricity bill, with an estimated payback time of 8 years.
