In recent years, the cost of solar energy has plummeted, and many engineers and homeowners are starting to look at solar as a viable alternative energy solution. And as solar enters mainstream energy markets, the big question is, "how does a solar panel work?" In this article, we'll break down exactly how solar panels produce energy for your home.
Firstly, you need to known "What are Solar Panels Made of?"
Photovoltaic solar panels are made up of many solar cells. Solar cells are made of silicon, like semiconductors. They are constructed with a positive layer and a negative layer, which together create an electric field, just like in a battery.
How does solar panels work for your home?
When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel, and multiple panels (modules) can be wired together to form a solar array. The more panels you can deploy, the more energy you can expect to generate.
Solar panels work by absorbing sunlight with photovoltaic cells, generating direct current (DC) energy and then converting it to usable alternating current (AC) energy with the help of inverter technology. AC energy then flows through the home's electrical panel and is distributed accordingly.
Here are the main steps for how solar panels work for your home:
1. Photovoltaic cells absorb the sun's energy and convert it to DC electricity
2. The solar inverter converts DC electricity from your solar modules to AC electricity, which is used by most home appliances
3. Electricity flows through your home, powering electronic devices.
