One way to make your life and home more eco-friendly is by using alternative energy. Solar power is a clean, safe, and cost-efficient form of alternative energy available. There are a few ways to harness solar energy, one of which is photovoltaic systems.

Guide to Photovoltaic Systems

What Are They?

Solar panels use photovoltaic cells that are comprised of several chemicals, including silicon and boron. The system converts sunlight directly to electricity, which is different from a concentrated solar power system that uses mirrors to gather sunlight and power a heat engine. Photovoltaic systems are also different than solar thermal energy, which is used to heat water or air for pools or buildings.

How Do They Work?

Light is made of photons, which are tiny particles of energy. When a photon collides with a molecule, it transfers its power and excites the electrons. These free electrons move and push other particles, creating an electric current.

The photovoltaic cells excite electrons in sunlight using two panels – one that’s negatively charged and another that has a positive charge. A circuit is created by attaching wires to the positive and negative sides of the cells. The electrons move through the channel, creating an electrical current that can power various systems in a home, including HVAC units and lights.

What Are the Benefits?

Unlike power sources, such as fossil fuels, the sun is an inexhaustible source of energy, and photovoltaic systems can gather energy that lasts 25 years or more. With an initial investment of solar panels on your home, you can harvest enough free solar energy to power your home for decades. By relying less on traditional fuels, you’ll reduce your carbon footprint and save money on electrical costs.
