Solar Array

March 15, 2024

What is a Solar Array?

A solar array refers to a collection of solar panels that work together to capture sunlight and convert it into electricity. They vary in size and complexity depending on a number of factors including available space, budget, and roof layout.

Panels are typically only installed in geographical locations that meet or exceed a 80% total solar resource fraction (TSRF) rating—the amount of sunlight a measured area will receive over a year. Abiding to this rating ensures that the system will produce sufficient energy and the property owner will save money in the long-run by installing the system.

Different Kinds of Solar Arrays

There are two major types of solar arrays: rooftop arrays and ground-mount arrays. Rooftop systems are installed on the roof of the home while ground-mount systems are positioned on a separate structure from the home.

Each kind of array presents its own advantages and disadvantages. Some major advantages of ground-mount systems are that you’ll avoid the risk of damaging your roof and can optimally position your panels to angle toward the sun, but some disadvantages include needing sufficient space on your property and having to delegate that space for the visible system.

A significant advantage of rooftop systems is that once they’re installed, you might even forget they’re there! They’re out of the way and hopefully blend nicely with your roof. Their disadvantage is that their positioning is highly dependent on your roof’s layout and you may be limited to placing them in non-optimal directions.
