How Solar Panels Work: Harnessing the Sun’s Power

At the heart of the solar revolution are solar panels, marvels of technology that convert sunlight into electricity. But how does solar energy work, exactly? Solar panels are made of photovoltaic (PV) cells, which absorb sunlight and trigger an electric current.

This current is converted from direct current (DC) to alternating current (AC), powering homes and businesses with the sun’s nearly endless energy. The beauty of solar power lies in its simplicity and efficiency. It provides a direct renewable source of energy that reduces reliance on fossil fuels and slashes our carbon footprint.

The Solar Spectrum: Renewable Energy Production in the U.S.

The U.S. renewable energy landscape is diverse, with solar energy leading alongside wind energy. With new solar projects coming online this year, the EIA forecasts that U.S. solar power generation will grow 75% from 163 billion kilowatt-hours (kWh) in 2023 to 286 billion kWh in 2025. Solar is far outpacing coal and other fossil fuel production in the United States.

This will boost the share of total generation capacity to 5.6% in 2024 and 7.0% in 2025, up from 4.0% in 2023. As we delve into facts about solar energy, it becomes clear that this isn’t just a fleeting trend. Solar power is a substantial pillar of the nation’s energy strategy today and going forward.

Shining a Light on Solar Options for Your Home

The solar world is full of innovations. Adopting solar power for your home is an excellent way to reduce your carbon footprint, gain energy independence, and lower your electricity bills. Better yet there are varying options to choose from in regard to how you utilize solar to power your home.

Here is a list of key home solar products to consider:

1. Solar Panels (Photovoltaic or “PV” Panels)
These are the most visible part of any solar system. Made up of photovoltaic (PV) cells, solar panels are designed to capture sunlight. When photons from the sun’s rays hit the semiconductive material (usually silicon) in the cells, they knock electrons loose. This movement of electrons creates a flow of direct current (DC) electricity.

How it works: Sunlight hits the panels, and the PV cells convert the solar energy into DC electricity. This DC electricity is then sent down wires to the solar inverter, whose job is to convert DC power into usable AC power for appliances and electronics within your home.

2. Solar Battery Storage
A solar battery allows you to store excess electricity generated by your solar panels for later use. This is particularly useful for grid-tied systems that want to maximize self-consumption and for off-grid or hybrid systems that need backup power.

How it works: During the day when your solar panels are producing more electricity than your home is using, the excess power is sent to the solar battery to be stored. Once the sun goes down or on a cloudy day, the stored energy can be discharged from the battery to power your home, reducing or eliminating the need to pull electricity from the utility grid. In the event of a power outage, the battery can power your home’s “critical loads” (like lights, refrigerators, and Wi-Fi) until the grid is restored.

3. Community Solar
Community solar emerged in the late 2000’s and has picked up massive momentum across the U.S. It allows everyone to benefit from solar power without installing panels or equipment.

How it works Community solar is when a group of people share electricity from a local solar farm. The model that allows multiple customers, such as individuals, businesses, and nonprofits, to benefit from a solar project within a specific region. Customers subscribe to solar panels located off-site. They receive a credit on their electric bill for the electricity produced by the portion of the community solar they own.

4. Retail Electricity Provider: These providers operate in deregulated energy markets where consumers can choose their electricity supplier. They procure electricity from large-scale solar farms and sell it directly to residential and commercial customers.

How it works: When you switch, your electricity provider takes your electricity supply payment and uses it to purchase renewable energy certificates (also known as renewable energy credits, or REC’s) on the behalf of you. Where you physically get your electricity from remains the same. However, now you’re helping offset your energy usage by ensuring more renewable power is entering the grid.

Together, these products offer varying degrees of utilizing sustainable energy system in your home all while minimizing your carbon footprint.

Common Solar Energy Myths vs. Solar Energy Facts (The Truth)

Myth 1: Solar panels do not work in cold, cloudy, or foggy climates.

Fact: Solar panels can still generate power in less-than-ideal weather conditions. They operate most efficiently in sunny conditions, but they can also produce electricity on cloudy or foggy days, and cold weather can actually improve performance by increasing their conductivity.

Myth 2: Solar energy costs are too high and unavailable for most people.

Fact: The price of solar energy installation has significantly decreased over the past decade, making it more accessible and affordable for homeowners and businesses. Additionally, many governments and organizations offer incentives, rebates, and financing options that further reduce the cost of solar installations.

Myth 3: Solar panels require a lot of maintenance.

Fact: Solar panels are relatively low maintenance. They may need occasional cleaning to remove dirt, leaves, or snow that could block sunlight, but generally, they require little upkeep to function efficiently.

Myth 4: Solar energy can only be used during the day.

Fact: While solar panels generate electricity during daylight hours, advancements in solar storage technologies, such as batteries, allow extra energy produced during the day to be stored and used at night, making solar energy increasingly versatile.

Myth 5: Installing solar panels can damage your roof.

Fact: When done correctly by a professional, solar panel installation does not damage your roof. In many cases, solar panels can actually protect the portion of the roof they cover by shielding it from the elements.

Myth 6: Solar panels take more energy to manufacture than they will ever produce.

Fact: Solar panels are designed to generate more energy over their lifetimes than the energy used in their production, transportation, and installation. The energy payback period can vary but is typically a few years. After that, the solar panels continue to produce clean energy, often for 25 years or more.

Myth 7: Solar energy is only for wealthy individuals or the eco-conscious.
