Bifacial solar panels are also known for their enhanced durability. They typically come with a glass-on-glass design, which improves their resistance to environmental stressors such as hail, heavy winds, and extreme temperatures. This robust construction not only extends the lifespan of the panels—often exceeding 30 years—but also reduces the need for frequent maintenance and replacements. Consequently, investing in bifacial technology can lead to long-term savings for both residential and commercial energy users.

Investing in a solar panel can provide long-term financial benefits. By generating your own electricity, you can reduce or eliminate your monthly utility bills. Additionally, solar panels can increase property value, making it a sound investment for homeowners. The payback period for solar installations can range from 5 to 10 years, depending on energy savings, local electricity rates, and the initial investment.

Understanding Small Solar Panel Systems

Many manufacturers are now producing solar panels with higher efficiency and durability, which can transmit a higher upfront cost but result in long-term savings on electricity bills. When evaluating the price, potential buyers should also consider the panel’s efficiency ratings, the warranties provided, and the anticipated energy output over the panel's lifespan, which can be around 25 to 30 years.

This added value is estimated by MaPrimeRénov (the French government’s renovation grant scheme) at between 15% and 25%. This is formalized in the Energy Performance Certificate (DPE) – a mandatory document when selling your property in France.
