Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight into electricity. They are typically installed on rooftops or in open spaces to capture solar energy.

Solar panels are made up of many solar cells, which contain semiconductor materials like silicon. When sunlight hits these cells, it excites the electrons, creating an electric current. This direct current (DC) electricity is then converted to alternating current (AC) by an inverter for use in homes and businesses.

Yes, solar panels can be a worthwhile investment in the UK. Despite the relatively lower levels of sunlight compared to some other countries, modern solar panels are efficient enough to generate significant amounts of electricity even on cloudy days. They can help reduce electricity bills and carbon footprint.

Solar panels typically have a lifespan of 25 to 30 years. Most manufacturers offer warranties that guarantee performance for at least 20-25 years. Over time, the efficiency of the panels may decrease slightly.

Solar panels require minimal maintenance. Regular cleaning to remove dirt and debris and periodic inspections to ensure all components are functioning correctly are usually sufficient. It is recommended to have a professional check the system every few years.
