Solar panels have grown in popularity over the last few years. They are an excellent source of energy that can be used by households, businesses, and even automobiles. This blog post will go over the science behind solar panels.
These cells are constructed of silicon semiconductor materials that absorb photons from the sun. When photons are absorbed, they knock electrons from silicon atoms, causing an electric current to flow.
Solar cells generate direct current (DC) electricity. However, alternating current (AC) electricity is used in the vast majority of buildings and appliances. As a result, the DC electricity must be converted to AC electricity using an inverter.
When solar panels are directly facing the sun, they are most efficient. Panel angle and direction are critical for maximum efficiency. The panels should be tilted at an angle equal to the location’s latitude.
Clouds can reduce solar panel efficiency by blocking some of the sunlight. Modern solar panels, on the other hand, are designed to be efficient even on cloudy days. Panels are evaluated and rated based on their ability to generate power in low-light conditions.
The temperature has an impact on solar panels as well. They can produce more power in colder temperatures than in hot temperatures. As a result, placing panels in a cooler environment can improve their efficiency.
Solar panels have a life expectancy of about 25 years. They can become less efficient over time due to environmental factors and wear and tear. The annual efficiency loss is typically around 1%.
Finally, solar panels provide a clean and renewable energy source that is becoming increasingly popular. Photovoltaic cells convert sunlight into electricity. The efficiency of solar panels is affected by their angle, direction, and environmental factors such as clouds and temperature. Solar panels can last up to 25 years if properly cared for.
