How do I plan a solar array?

Knowing how much power you need is the first step to planning your array. Since solar panels are measured by how much energy they can absorb, this will tell you how many panels to buy, how efficient they need to be, and (perhaps most importantly) how much space you're going to require.

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.

How does a solar array work?

Your array is connected to an inverter or multiple inverters, which convert the DC electricity generated by the solar cells in your panels into usable alternating current (AC) electricity. The term solar array is often also used to describe large-scale solar projects; however, it can refer to just about any grouping of solar panels.

What is a PV array?

The array is built of strings of modules connected in parallel, each string consisting of modules connected in series. This block allows you to model preset PV modules from the National Renewable Energy Laboratory (NREL) System Advisor Model (2018) as well as PV modules that you define.

What is a solar array & why is it important?

The solar array is the most important part of a solar panel system – it holds all the panels in your system, collects sunlight, and converts it into electricity. In this article, we'll share some common questions to ask yourself before installing a solar panel system on your home and ensure you get the most productive array possible.

What is a residential solar array?

The term solar array is often also used to describe large-scale solar projects; however, it can refer to just about any grouping of solar panels. In this article, we'll focus on residential solar arrays, which are typically located on your roof.
