Solar Array: Everything A Homeowner Needs to Know

A solar array is a central component of a solar panel system. A solar panel array is a collection of solar panels that convert solar energy into electricity in a solar panel system. Before installing a solar energy system on the roof, the homeowner should know some basic concepts about the solar array. 

The size of an array varies from home to home. It depends upon the residential location, the roof position & the power demand of a home. 

This article will be helpful if you are planning to install a residential solar system. We have highlighted some common queries about solar arrays so that you can make sure to design an efficient solar array. 

What is a Solar Array?

As mentioned above, A solar array is a set of solar panels that work together to produce electricity. A completely functional solar energy system is made up of solar arrays, one or more solar inverters, and, optionally, a battery. 

A solar array is a part of a solar energy system that generates electricity that can be used to power a home or exported to the grid. When sunlight strikes the panels in an array, it generates the direct current (DC). It connects to an inverter system that transforms DC electricity into usable alternating current (AC) electricity.

We’ll talk about home solar panels, which are usually installed on your roof.

How is a Solar Array Made?

A solar array is a circuit made up of solar panels that have been linked together.

Solar panels, on the other hand, are made up of photovoltaic (PV) solar cells that are protected by glass and kept together by a metal frame. Solar cells are formed of extremely thin slices of semiconductor material, usually silicon.

Individual solar cells use the photovoltaic process to generate electricity: photons in sunlight separate electrons from silicon, resulting in an electric charge. Solar panel systems are sometimes known as ‘PV systems’ because of this procedure.

The number of solar panels used is determined by the wattage (power output) of each panel as well as the intended total system size. A 7,000 watt (7 kW) domestic solar system, for example, could be built using 28 solar panels rated at 250 watts each or merely 19 solar panels rated at 375 watts each.

Does array location matter?

It’s necessary to inquire about the system design and the place where the solar panels will be installed from any installer. A solar array facing straight south in the Northern Hemisphere will produce more electricity than one facing west, east, or north because it will receive more hours of sunlight.

Rooftops are a popular location for solar panels, but they’re far from the only option. If you have a lot of land and enough sunlight, a ground mount would be a better option. Rather than being confined by the dimensions of a roof, ground-mounted arrays are faced and angled optimally for maximum production. 

Solar panels are sometimes mounted on other structures, such as carports and gazebos, in addition to rooftops. Because these types of installations aren’t as popular, you may need to inquire around to find an installer who can design and install this type of system in your area. Because of the additional components necessary for installation, there may be some additional expenditures connected with a stand-alone construction.

How does a solar array work?

A solar array can be used for energy generation for 25 years (their warranted life) or longer. Energy is produced without the use of moving components, fuel, or any other form of human interaction. 

Here’s a quick rundown of how a solar array can power a solar energy system at home:

• Power Generation: The solar cells in the array are activated by sunlight, which generates Direct Current (DC) electricity. Solar cells in the array are activated by sunlight, resulting in the generation of Direct Current (DC) electricity.
• Power Conversion: The DC power is then sent to an inverter, which converts it to AC electricity that may be used in the home.
• Power Consumption: The 120/240 volt AC power supply is then used on-site (by the residence) or exported to the grid, where it can be supplied to those who require electricity.

How to calculate the size of a solar array?

The ability of a solar panel system to create electricity is described as solar array size.

Under normal conditions, a solar array of 300 watts can provide 300 watts of electricity. While a solar system of 6 kilowatts may create 6,000 watts.

Your energy use, available roof space, and the amount of sunlight where you live all play a role in determining the size of the solar array.

For instance, Assume you desire a solar array large enough to eliminate your electric bill. In that instance, a solar array is capable of producing 1,000 kWh of electricity per month. This may be appropriate for homes but your energy needs may vary) according to the EI.

In different locations of the country, you’d require the following solar array sizes to produce 1,000 kWh:

How much does the solar array cost?

In the United States, a complete residential solar panel system costs between $18,000 and $20,100. According to the cost statistics, the national average in October 2021 was between $2.75 and $3.35 per watt of solar installed.

How many solar panels will an array require?

The solar panels’ number that you’ll require is determined by the size of your monthly electric bill (among some factors). If you strive to cover as much of your electricity consumption as possible, you will save the most money. If your home’s energy needs are different from your neighbor’s, this may mean you’ll need to add a few more panels.

The number of panels you’ll need to cover your electricity consumption is also determined by the panels’ location, both in terms of your geographic region and the design itself. In terms of location, a solar panel in California will produce more electricity than a solar panel in New York, assuming all other factors are equal because California receives more sunlight throughout the year. When estimating the production of your solar panel system, installers take your location into account and suggest a design accordingly.
