Päikesepaneelid, or solar panels, are devices that convert sunlight into electricity. They are a key component of solar energy systems, which harness the power of the sun to generate renewable energy. Solar panels are typically made of photovoltaic (PV) cells, which are semiconductor materials that absorb photons from sunlight and release electrons, creating an electric current.

The efficiency of solar panels refers to the percentage of sunlight that is converted into usable electricity. As of recent advancements, the efficiency of commercial solar panels ranges from 15% to 22%, with experimental panels reaching up to 47%. Factors affecting efficiency include the type of PV material, the quality of manufacturing, and environmental conditions such as temperature and shading.

Solar panels can be used in various applications, from small-scale residential systems to large-scale utility projects. They are particularly beneficial in areas with abundant sunlight and can significantly reduce or eliminate electricity bills for homeowners and businesses. Additionally, solar panels contribute to environmental sustainability by reducing reliance on fossil fuels and lowering greenhouse gas emissions.

Installation of solar panels involves mounting them on rooftops or in open fields and connecting them to an inverter, which converts the direct current (DC) produced by the panels into alternating current (AC) suitable for use in homes and businesses. The electricity generated can be used immediately or stored in batteries for later use.

Maintenance of solar panels is relatively low, primarily requiring periodic cleaning to remove dust and debris and occasional checks to ensure all connections are secure. With advancements in technology, solar panels are becoming more affordable and accessible, making solar energy an increasingly viable option for both residential and commercial energy needs.
