The sun provides constant energy to the Earth's surface. In fact, all sources of energy on Earth come from the sun in one way or another. Solar panels harness the sun's energy directly, providing a clean and efficient source of power. Using solar panels to power your home can help you save on energy expenses, achieve grid independence and reduce your carbon footprint. Owning solar panels is an attractive investment for any rural homeowner.
If you're considering investing in solar panels, you may find it helpful to learn how they work. Although most people are familiar with the idea of solar energy, not everyone understands what solar panels do — what actually happens within the system to produce electricity. Discover how solar panels can provide your rural home with energy.
Most solar energy systems convert sunlight into electricity or heat water. Some systems gather energy from the sun's heat — this technology is called thermal solar. However, most systems use solar panels with photovoltaic (PV) technology to harness the energy in the sun's rays.
Most solar energy systems gather the sun's energy using photovoltaic cell technology to produce electrical charges. Each PV solar system consists of a collection of individual solar cells. To understand how a PV system works, you should know a bit about basic physics.
Solar cells contain electrons, which are tiny particles of matter that circulate atoms' nuclei. Electrons have a negative charge, which means they repel other electrons and are attracted to protons, like magnets. Electrons move and create an electrical current when exposed to energy, like photons. Photons are tiny packets of energy, not matter. The sun's rays contain photons, as do microwaves, X-rays and all other forms of electromagnetic rays.
PV technology converts the photons in sunlight to produce usable electricity. Each PV cell contains semiconductor materials that let electricity flow when exposed to energy, such as photons. The semiconductor is processed into a wafer to form a diode, which allows electricity to move in one direction only rather than multiple. The process works like this:
Now that you know the basics of how solar panels produce electricity, the next question is what happens with that energy. Here's a step-by-step breakdown of where the power goes:
In short, the PV technology within solar panels captures sunlight's energy and makes it a usable electric current. This electric current disperses to all the things that use electricity in your home.
Although all PV solar panels work in the same basic way, you'll find different types of solar panels with diverse characteristics. In general, there are three major types of solar panels — monocrystalline, polycrystalline and thin-film. They vary in appearance, construction, performance, cost and installation. For these reasons, the type of panel you choose is significant.
Solar panels use the sun's rays to generate electricity you can use to power your home. The process is clean, safe and environmentally friendly. You might have several different reasons for wanting to produce your own energy with solar technology. Here are a few reasons to invest in solar:
It's helpful to understand how solar panels work to provide clean, renewable energy to homes and businesses. Most solar panels use PV technology, which captures the photons in sunlight to create an electric current. The system then converts the current of the electricity so you can use it to power your appliances. Different types of PV solar panels vary in materials, cost and effectiveness.
