6 FAQs about [Photovoltaic solar arrays]

What is a photovoltaic array?

A photovoltaic array, or solar array, is a linked collection of solar modules. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array.

What is a solar array?

A solar array is a collection of multiple solar panels that generate electricity. When an installer talks about solar arrays, they typically describe the solar panels themselves and how they're situated – aka the entire solar photovoltaic, or PV system. To create solar energy, sunlight must hit your panels' photovoltaic cells.
