Solar Energy Basics:

What Is Solar Energy?

Solar energy is the radiant power harnessed from the sun‘s rays, which can be transformed into electricity by photovoltaic (PV) panels. As sunlight strikes these panels, the PV cells within capture the sun‘s energy and initiate a process where electrical charges are generated and set in motion. This movement, driven by an internal electrical field, ultimately results in a continuous flow of electricity.

How Do Solar Panels Work?

Solar panels are made up of photovoltaic cells, which are composed of layers of semiconductor materials. These materials absorb photons from sunlight, causing electrons to be released and creating a flow of electricity. This electricity is then converted from direct current (DC) to alternating current (AC) using an inverter, which can be used to power appliances or be fed back into the grid.

What Are Solar Inverters?

Solar inverters convert direct current (DC) electricity that a solar panel generates to alternating current (AC) electricity, which the electrical grid uses.

How Much Do Solar Panels Cost?

The typical cost per watt is $2.50-$3.50. An average US household consumes nearly 11,000 kilowatt hours annually requiring a 6-9kw system. The cost of solar panels depends on various factors, such as size, location, and energy usage.

How Long Do Solar Panels Last?

Solar panels generally last more than 25 years, with manufacturers typically offering warranties of 20-25 years. However, their efficiency may decline over time, usually at a rate of less than 1% per year.

Can I Use Solar Energy In a Power Outage?

You can only use solar energy during a power outage if you have a battery storage system. Without a battery system, your solar panels won‘t work to ensure the safety of utility workers who are working to restore power.

Can I Monitor My Solar Panel System?

Yes, you can monitor your solar panel system using various monitoring services and apps. These tools help you track your system‘s performance, energy production, and any potential issues that may arise.

What Is Net Metering?

Net metering is a billing system that allows homeowners and businesses to sell excess energy produced by their solar panels back to the grid, receiving credit on their electricity bills. This arrangement helps offset energy costs and promotes renewable energy production.

Learn More

Do Solar Panels Need Direct Sunlight to Work?

Solar panels can still produce energy without direct sunlight, but energy production may be reduced. This is because photovoltaic (PV) panels use particles of light, called photons, to generate electricity. Photons are present in direct and indirect sunlight, so solar panels can operate in both conditions.
