How does solar power work?

Sunshine equals savings.

The sun, sometimes called the sky’s power plant, emits enough energy to earth to meet the world’s power needs and then some. The sun’s light, which is full of energy, can be captured and turned into an electrical current which can be used as power.

Maybe you’ve heard all of this before, but you’re still wondering how harnessing energy from the sun can save your hard earned cash. Or maybe you’ve heard about solar power, but you’re left asking, “how does sunshine become electricity?”

Although solar power might seem futuristic, it’s already quite common. Do you have solar-powered lights in your garden? Or maybe you have a solar-powered calculator in your office or a quartz watch on your wrist. See, not so strange!

With an increasing demand for renewable energy, solar power is becoming a popular energy choice. Solar power doesn’t emit carbon dioxide, it won’t run out, and it’s free! What’s not to love?

So how does it work?

Solar panels capture the sun’s rays during and convert it to direct current (DC) electricity.

Photovoltaic (PV) cells, more commonly referred to as solar panels, capture the sun’s rays during and convert it to direct current (DC) electricity. Basically, photovoltaic cells take sunlight and produce electricity. They are simple in structure, very durable, and effective! They have no moving parts, so they are low-maintenance. They are usually installed on a roof that will be south facing, or south-east or south-west facing. This ensures they capture as much energy as possible.

Once the sun’s rays are captured, an Inverter converts the direct current electricity to alternating current (AC) electricity, which is the type of electricity that can be used within your home.

The converted alternating current power is sent from the inverters to your home’s wiring system to power your appliances, lights, and anything else that uses electricity within your home. The electrical panel is often referred to as a switchboard or a breaker box.

A utility grid/meter measures the energy you use and monitors how much extra energy is saved in your grid. Sometimes you might not need to use all of the power produced from your PV system. The excess power is put into the public grid and your power company will give you credit for the electricity you contributed.

Solar power is an investment. Many of our clients see paybacks in as quick as 10 years. Aside from saving money and the environment, solar power is almost hassle-free and might be the perfect option for you home or workplace.



Here at SunAir Energy Solutions can accommodate projects of any size from off-grid, to grid-tied to commercial installations.  We’re proud to offer a variety of solar products including, KACO, SolarEdge, Enphase Energy, Schletter, Jinko, and Canadian Solar products.

Most solar panels have a 25-year output warranty, meaning that the panels will still produce up to 80% of the energy compared to a new panel, as solar panels degrade from 0.5% to 1% annually. They also generally have a 10 or 12-year manufacturer’s warranty for defects. SolarEdge and Enphase have 25 year warranties on their products and KACO string inverters have a 10-year warranty for full replacement. We strive to install quality products with strong warranties and service what we sell.
