FAQs

WHAT IS A PHOTOVOLTAIC SYSTEM?
A photovoltaic (PV) system is a technology that converts sunlight directly into electricity through the photovoltaic effect. Within this system, solar panels composed of numerous individual solar cells are the primary component that captures solar energy. These cells, often made from silicon, generate DC electricity when sunlight interacts with their semiconductor material. The generated electricity can either be used on-site, stored in batteries, or fed back into the electrical grid. A complete photovoltaic system typically includes additional components such as inverters, which convert the DC electricity into AC electricity for use in homes and businesses, and mounting structures to secure the panels to rooftops or ground installations.

HOW DO SOLAR PANELS WORK?
Solar panels function by utilizing the photovoltaic effect to transform sunlight into electricity. Each panel is comprised of numerous solar cells that generate electric current when exposed to sunlight. When photons from sunlight strike the surface of a solar cell, they energize electrons within the material, causing them to break free from their atomic bonds, creating a flow of electric current. This direct current is then directed to an inverter, where it is converted to alternating current, making it compatible for household or commercial use. The efficiency of solar panels is influenced by factors such as the quality of materials, alignment toward the sun, and the absence of shading. Additionally, advancements in design and engineering continue to improve solar panel efficiency and energy conversion rates.

WHAT FACTORS AFFECT SOLAR PANEL EFFICIENCY?
Solar panel efficiency can be impacted by a variety of factors, including temperature, sunlight intensity, shading, and panel orientation. For instance, higher temperatures can reduce the efficiency of solar cells, as excess heat can hinder electrical output. Additionally, shading from trees, buildings, or other obstructions can limit the amount of sunlight reaching the panels. The angle and orientation of solar panels are also critical; panels positioned to maximize exposure to direct sunlight throughout the day will generally produce more electricity. Environmental conditions such as dust and debris accumulation can further detract from efficiency by blocking sunlight. Regular maintenance and optimal system design can help mitigate these issues, ensuring sustained performance and higher energy yield.
