Why Install Solar Panels in Your Home?
In Pakistan, electricity prices are unpredictable and inflation is on the rise, making life increasingly difficult for the average person. In many regions, access to electricity is not available 24/7, even in the 21st century. Solar panels offer a reliable, cost-effective solution to these issues, providing a consistent power supply while reducing monthly electricity bills. Solar energy is also a clean, renewable source, making it an environmentally friendly option that reduces your carbon footprint.
Solar Panels: An Overview
Solar panels work by converting sunlight into electricity through the photovoltaic effect, a phenomenon discovered in 1839 by French physicist Alexandre Edmond Becquerel. Solar cells within the panels are made of semiconductor materials like silicon, which generate an electric current when exposed to sunlight. The panels are encased in layers of protective material, with the bottom layer collecting and transporting the generated electricity.
In Pakistan, solar energy is increasingly used in residential, commercial, agricultural, and industrial sectors. Here, we will explore some of the top solar panel brands available in the country.
