The solar array is the pinnacle of solar energy technologies and the key to unlocking the sun’s limitless potential. A solar array is more than just a group of solar panels; it stands for a revolutionary force in our pursuit of cleaner and more effective electricity generation.

In this article, we unveil the essential facets of solar arrays, shedding light on their components, working principles, and the remarkable impact they have on our energy landscape.

What Is a Solar Array?

A solar array is a group of connected photovoltaic (PV) or solar panels that are used to collect sunlight and generate electricity. To maximize exposure to sunlight throughout the day, these panels are typically mounted on a support structure, such as a rooftop or ground-mounted system.

Utilizing the energy from the sun’s rays to produce clean, renewable electricity is the main goal of solar panels arrays. Utilizing this electricity to run homes, businesses, or other electrical equipment lessens the need for fossil fuels and lessens the environmental impact. The transition to more environmentally friendly and sustainable energy sources depends heavily on solar arrays.

The photovoltaic effect is used by solar panel arrays to turn sunlight into electricity. They are made up of connected solar cells made of silicon or another semiconductor material. These cells are exposed to sunlight, which energizes the material’s electrons and permits free movement. Electric current is produced by the movement of energized electrons and is collected by metal conductive plates on the sides of the cells.

Direct current (DC) is the form of electricity generated, which is similar to what batteries offer. An inverter is used to change the DC electricity into alternating current (AC), which is the preferred form for use in electrical grids and home appliances, making it suitable for the majority of applications, particularly for powering homes and businesses.

The electricity can be used to power nearby electrical loads or returned to the grid once it has been converted to AC. In many instances, surplus energy can be sold back to the grid, benefiting the owner financially and helping to create a cleaner energy mix. This procedure lowers carbon emissions and decreases reliance on fossil fuels.

Where Can You Put Solar Arrays?

To effectively harness solar energy, solar panels arrays can be installed in a variety of locations. The following are some typical locations for solar arrays:

  • On Rooftops: One of the most popular options for homes and businesses is rooftop solar arrays. They install solar panels on the available roof space, making efficient use of otherwise unutilized spaces.
  • Ground-Mounted Systems: On open land or on objects mounted to the ground, solar panel arrays can be installed. This choice is appropriate for massive solar installations, like solar farms, where there is plenty of available space.
  • Solar Carports: Solar panels can be incorporated into parking garages or carports to shade cars while producing electricity. This dual-purpose solution is frequently used in institutional and commercial settings.
  • Building-Integrated Photovoltaics (BIPV): Solar panels are incorporated into building components like windows, facades, and roofing materials as part of BIPV. This seamlessly integrates solar energy production into the building’s design.
  • On Water Bodies: Floating solar arrays, also referred to as “floatovoltaics,” are positioned on bodies of water like lagoons for wastewater treatment, ponds, and reservoirs. Due to their ability to conserve land and keep solar panels cool, these systems are becoming more and more popular.
  • Solar Trackers: To maximize sunlight exposure throughout the day, solar tracking systems can be used with installations that are either ground-mounted or roof-mounted. To increase energy production, these trackers move in the direction of the sun.
  • Solar Canopies: Solar canopies are buildings with solar panels mounted on top, producing electricity and offering shade. Outdoor areas like parks, walkways, and recreational areas frequently use them.
  • Remote Locations: In remote areas with limited access to the electrical grid, solar arrays are used. They supply electricity to remote monitoring devices, telecom towers, and off-grid cabins.
  • RVs and Boats: RVs and boats can be equipped with solar panels to generate clean energy for appliances, lighting, and onboard systems.
  • Residential Installations: Residential buildings, such as homes and apartments, can have solar arrays installed to produce clean electricity for residents and lower their electricity costs.

The suitability of a particular site for a solar array depends on elements like the amount of sunlight, regional laws, the amount of available space, and the installation’s intended use. In order to ascertain the viability and effectiveness of solar panels arrays in a specific location, a site assessment is typically carried out.

Can You Add Capacity to Your Solar Array in the Future?

It is frequently feasible to expand the capacity of your solar array in the future, but this depends on a number of different factors. These considerations include the amount of available space, the inverter’s capacity, the electrical grid, local laws, the use of net metering, the warranty and compatibility, and the appropriateness of the system design.

In order to increase the size of your solar array, you may need to make changes to your electrical system, add more space for panels, and comply with local laws. You may also want to consider upgrading or adding inverters.

It is crucial to take into account the financial ramifications, including the initial investment and potential long-term savings. Furthermore, find out if increasing your solar capacity could have an impact on the net metering rules and charges implemented by your utility.

Consult with a qualified solar expert before moving forward with an expansion so they can evaluate your unique circumstances, assist you in designing the expansion, and make sure the new panels work in tandem with your current system.

How Large Should Your Solar Array Be?

Your energy consumption, location, financial situation, and available space are just a few of the variables that will determine the size of your solar array. Take a look at the examples below to determine the size of your solar array:

  • Residential Usage: Start by reviewing your previous energy usage if you’re a homeowner hoping to reduce some of your electricity bill. To find out how many kWh (kilowatt-hours) you use on average each month and annually, review your utility bills. A general rule of thumb is that in a sunny area, each 1 kW of solar capacity can produce approximately 1,200 kWh of electricity annually. You may therefore need an 8–10 kW solar array to meet the majority of your needs if your annual electricity consumption is 10,000 kWh.
  • Off-Grid Living: The solar array on your home must produce all the electricity required for those who live in remote areas without access to the grid. In this situation, your daily energy needs, the number of sunny days, and the amount of battery storage you have will all affect the size of your array. Solar panels with a capacity of 5 kW to 20 kW or more may be necessary for a typical off-grid home.
  • Commercial and Industrial: Companies should evaluate their energy use patterns and objectives. Larger industrial and commercial facilities might have high energy needs. A manufacturing facility that uses 100,000 kWh per month, for example, might need a 200–500 kW solar array or more to offset a sizable portion of its consumption.
  • Agricultural Applications: Solar arrays are useful for farms because they can power livestock operations, irrigation systems, and other things. The size of the array would be determined by the particular needs of agriculture, such as the amount of power needed for pumps, lighting, and other machinery.
  • Government and Utility-Scale: Utility-scale solar arrays can produce between a few and hundreds of megawatts of electricity, enough to power thousands of homes. Large tracts of land or open spaces are needed for these projects, as well as extensive planning.
  • Budget Constraints: The size of your solar array is greatly influenced by your budget. If you have a tight budget, you can install a smaller system that only meets a portion of your energy requirements, or if you have the money, you can install a larger system.
  • Space Availability: The size of the array will also depend on the physical space that can be used for solar panels. You might need to install a smaller array or look into different options like solar tracking systems or more efficient panels if you have limited roof space or ground space.

Working with a reputable solar installer or engineer is essential to determine the best size for your solar arrays because they can evaluate your site, take into account your energy needs, and make a recommendation that is tailored to your individual situation.


In conclusion, solar arrays are a remarkable and adaptable way to capture the sun’s free, clean energy.
