FAQS

WHAT ARE THE MAIN COMPONENTS OF A SOLAR POWER SYSTEM?

A solar power system primarily consists of solar panels, an inverter, a charge controller, and storage batteries. Solar panels capture sunlight and convert it into electricity through photovoltaic cells. The inverter then transforms the direct current (DC) produced by the panels into alternating current (AC), which is the standard for most home appliances. The charge controller regulates the voltage from the solar panels to ensure that the batteries are charged appropriately without overcharging. Lastly, storage batteries allow excess energy generated during sunny periods to be stored for use during cloudy days or at nighttime. Together, these components function cohesively to harness solar energy efficiently for residential or commercial use, providing a reliable and sustainable energy solution.
