As the adoption of solar energy continues to grow, homeowners are increasingly exploring the benefits of transitioning to this renewable power source. However, navigating the solar industry can often feel like learning a new language, with a seemingly endless array of technical terms and jargon.

At Bracket, we believe that empowering homeowners with a clear understanding of solar terminology is the key to making informed decisions and unlocking the full potential of this clean energy solution. In this comprehensive glossary, we'll break down the essential solar terms that every homeowner should know.

Photovoltaic (PV) Panels

The heart of a solar energy system, photovoltaic panels (also known as "solar panels") are the devices that convert sunlight into usable electricity. These panels are made up of individual solar cells that work together to generate direct current (DC) power.

Inverter

The inverter is a critical component in a solar energy system, as it transforms the DC electricity generated by the PV panels into the alternating current (AC) electricity that powers your home's appliances and electronics. There are several types of inverters, including string inverters, microinverters, and power optimizers.

Net Metering

Net metering is a billing arrangement that allows homeowners with solar energy systems to receive credit or compensation for the excess electricity they generate and send back to the utility grid. This ensures that you are compensated for the clean energy you contribute to the local power supply.

Solar Insolation

Solar insolation refers to the amount of sunlight that hits a specific area, and it's a key factor in determining the energy-generating potential of a solar energy system. Geographic location, weather patterns, and seasonal changes can all impact solar insolation levels.

Renewable Energy Credits (RECs)

Renewable Energy Credits, or RECs, are tradable certificates that represent the environmental benefits of producing one megawatt-hour (MWh) of renewable electricity. Homeowners with solar energy systems may be able to sell their RECs to utility companies or other entities, providing an additional source of revenue.

Payback Period

The payback period is the amount of time it takes for the savings and benefits of a solar energy system to offset the initial investment. This is an important consideration when evaluating the long-term financial viability of going solar.

By familiarizing yourself with these key solar terms, you'll be better equipped to navigate the solar energy landscape, ask informed questions, and make the best decision for your home and your energy needs.
