Solar Array

Size And Structure of Solar Arrays

A solar array is any order or group of solar panels with the intent to capture and transform sunlight into some other form of energy. The size and installation of a solar array depends on what is needed. Anyone looking for enough electrical energy to power an entire house will need a totally different solar array than one who only wants to heat some water.

Usually, solar arrays are used for energy production or water heating. It can also be a combination of two solar system types. As soon as we need more solar power or hot water than a single photoelectric or thermal panel can produce, multiple panels must be arranged as a solar array.

A solar array can be as big as we need it to be and deliver enough energy or warm water for an entire house or more. As photovoltaic or thermal power plants, solar arrays can also have huge dimensions like the solar array ‘Aurora’ in Colorado.

At the end of the manufacturing process of solar panels, the solar array structure for the mechanical panel integration is chosen.


The arrangement of a solar array depends on its final location which could be on a roof, as integration into building materials for roofs or vertical walls. Other options are pole-mounting, ground-mounting, or attaching of a solar panel to an industrial structure.

After the solar module assembly and the adjustment of a solar array, the electrical components are integrated with other parts of the solar energy system. This includes the connection of elements of solar arrays such as inverters, batteries, wiring, disconnects and regulators (charge controllers).

An important aspect which must be considered before installing a solar array is the placement. Solar Arrays must be placed at an angle that will best capture the most direct sunlight.

Active and passive solar trackers can help the solar array become more efficient. Any shade or light obstructions will inhibit the efficiency.
