How Solar Power Works

Solar power is harnessed by utilizing photovoltaic (PV) cells, which convert sunlight into electricity. These PV cells are typically assembled into solar panels, which are then installed on rooftops or other suitable locations to capture sunlight. The captured sunlight is then converted into usable electricity through an inverter, which transforms the direct current (DC) energy into alternating current (AC) energy compatible with home appliances and the power grid.


Your Home’s Suitability for Solar Power

Before diving into solar power installation, it’s important to assess your home’s suitability for solar energy. Here are some key factors to consider:

1. Roof Orientation and Shading: The orientation of your roof plays a crucial role in maximizing solar energy generation. Ideally, a south-facing roof receives the most sunlight throughout the day. Additionally, shading from nearby trees or buildings can reduce the efficiency of solar panels. Assess your roof’s exposure to sunlight and ensure minimal shading for optimal performance.
2. Solar Site Assessment: Conducting a solar site assessment helps determine the solar potential of your property. A professional solar installer can evaluate your roof’s structural integrity, assess shading issues, and calculate the expected energy output based on your location and other factors. This assessment will help you make informed decisions during the solar installation process.
