Installing photovoltaic panels in a new home is becoming an increasingly popular choice for people looking for alternative energy sources. By harnessing sunlight, it is possible to generate electricity that will cover household energy needs while also contributing to the reduction of greenhouse gas emissions. However, before you decide to proceed with a photovoltaic installation, it is worth understanding a few important aspects that will help you make an informed decision.
Benefits of photovoltaics
The advantages of using solar panels are undeniably compelling. First and foremost, a photovoltaic installation allows you to reduce electricity bills. By generating your own power and consuming it directly, you can save a significant portion of your household budget in the long term. In some cases, when energy production exceeds consumption, the surplus can be fed back into the grid, providing the opportunity to gain financial benefits.
Another key advantage is that photovoltaics represent one of the most environmentally friendly methods of generating energy. Solar panels emit neither greenhouse gases nor other pollutants, meaning that by choosing photovoltaics, you actively contribute to reducing your carbon footprint. In many European countries, including Luxembourg, the installation of solar panels may qualify for various subsidies or tax incentives, which makes investing in photovoltaics even more cost-effective.
What to consider before installation?
The decision to install a photovoltaic system should not be made hastily. Before starting, it is important to take into account a few technical aspects that can affect the overall efficiency of the system. The first is the location of your home, specifically the level of sunlight it receives. In regions with higher solar exposure, such as southern Europe, solar panels can generate even greater savings. In Luxembourg, despite its moderate climate, good results can still be achieved with a well-designed installation.
Another aspect is the structure of the roof where the panels will be mounted. The roof should be in good technical condition and capable of bearing the additional weight of the panels. It is also important to consider the roof’s tilt angle, which should allow for optimal positioning of the panels in relation to the sun. The most effective orientation is typically toward the south, but depending on slope and orientation, specialists can design the system to make the most of available solar radiation.
Another crucial factor is the size of the installation, which should be matched to your household’s energy demand. A system that is too small may not cover all your energy needs, while one that is too large involves unnecessary costs. It is therefore advisable to carefully assess your energy requirements, including future ones, particularly if you plan to expand your home or purchase new appliances that will require more electricity.
Cost of installation and available financial support
Although the initial cost of installing a photovoltaic system can be high, in the long run this investment pays off considerably. The cost of panels, the inverter, cabling, and the installation itself can amount to several thousand euros, but the final price depends on many factors, such as the system size, the type of components used, and labor costs. Additional expenses may also arise if roof reinforcement or structural modifications are required to accommodate the panels.
It is also worth considering the financial support available, which can significantly reduce the investment cost. In Luxembourg, as in other countries, there are subsidy programs for homeowners who decide to install photovoltaic panels. These incentives may include partial reimbursement of installation costs, which greatly increases profitability. Tax relief for renewable energy investments may also be available.
While the initial cost may seem high, photovoltaic panels are a long-term investment. On average, panels have a lifespan of around 25–30 years, with their efficiency decreasing by only a few percent per year. This means you will benefit from reduced electricity bills and protection against rising energy costs for many years. In addition, in some countries, the possibility of selling surplus energy back to the grid provides an additional source of income.
Conclusion
A photovoltaic installation is an investment that brings tangible financial and ecological benefits in the long term. Installation of a photovoltaic system by Voltmax should be preceded by a technical analysis taking into account factors such as sunlight exposure, roof condition, and household energy needs. Although the initial cost may be high, the availability of support schemes and the resulting savings on electricity bills make solar panels an increasingly profitable solution.
