Solar Energy

Solar energy is the radiant light and heat from the sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.

How Solar Energy Works

When sunlight hits a solar panel, the photovoltaic cells within the panel convert the sun's energy into electricity. This process is known as the photovoltaic effect. The electricity generated by the solar panels can be used to power homes, businesses, and even entire cities.

Benefits of Solar Energy

• Renewable: Solar energy is a renewable resource, meaning it will never run out.
• Clean: Solar energy production does not produce air or water pollution, making it environmentally friendly.
• Cost-Effective: Once solar panels are installed, the energy they produce is essentially free, leading to long-term cost savings.
• Low Maintenance: Solar panels require very little maintenance, reducing the overall operating costs.
