Solar power generation installation and use

What is solar photovoltaic (PV) power generation?

Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.

Where is solar energy used?

It is used primarily in very large power plants. Solar energy technology doesn’t end with electricity generation by PV or CSP systems. These solar energy systems must be integrated into homes, businesses, and existing electrical grids with varying mixtures of traditional and other renewable energy sources.

Should I add a solar energy system to my roof?

You may be considering the option of adding a solar energy system to your home’s roof or finding another way to harness the sun’s energy. While there’s no one-size-fits-all solar solution, here are some resources that can help you figure out what’s best for you. Consider these questions before you go solar. See the Spanish version here.

How long does it take to install a solar power system?

Installation of solar power system. The installation of a solar power system on your property can take anywhere from 1–7 days, depending on the availability of contractors, permits, and materials required.

How do I choose the best way to use solar electricity?

Before deciding on the best way to use solar electricity at home, assess the potential solar energy that can be produced at your address. Because PV technologies use both direct and scattered sunlight to create electricity, the solar resource across the United States is ample for home solar electric systems.

How is solar power generated?

Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity. It is one of the fastest-growing renewable energy technologies and is playing an increasingly important role in the global energy transformation.
