These cells are typically made from semiconductor materials, most commonly silicon, which have the ability to convert sunlight directly into electricity through the photovoltaic effect. When photons from sunlight strike these semiconductor materials, they excite electrons, causing them to flow and generate a direct current (DC) of electricity.
The efficiency of solar panels is a crucial factor for consumers. Modern panels often boast efficiencies ranging from 17% to over 22%, meaning that 17% to 22% of the sunlight that hits the panel is converted into usable electricity. This efficiency is influenced by factors such as the type of silicon used (monocrystalline silicon panels generally offer higher efficiency than polycrystalline ones), the quality of the manufacturing process, and the presence of anti-reflective coatings. As technology continues to evolve, we can expect even higher efficiencies and improved performance in various weather conditions.
Beyond the basic PV cells, solar panels incorporate several other important components. A protective glass layer shields the cells from environmental damage like hail, dust, and moisture. An encapsulant, typically made of EVA (ethylene vinyl acetate), holds the cells in place and protects them from impact and weathering. The backsheet provides further insulation and protection, while an aluminum frame offers structural integrity and facilitates mounting. These integrated components work together to ensure the durability and longevity of solar panels, typically with warranties lasting 25 years or more.
Factors to Consider When Choosing Solar Panels
When embarking on the journey to install solar panels, several critical factors demand careful consideration to ensure you make the most informed decision for your specific needs.
