Understanding solar panel dimensions and a solar panel system&#;s output, quality and efficiency can help you choose the right panels for your property. In general, solar panels are measured by how many cells they contain. This complete guide to solar panel size can help you determine each panel type&#;s dimensions.
How Big Are Solar Panels?
Solar panels are not typically measured in feet. Instead, manufacturers declare a solar panel size based on how many cells a panel contains. Solar cells are small squares that contain the materials responsible for absorbing sunlight and converting it to energy.
Standard solar cells are 6 by 6 inches, and a solar panel&#;s dimensions depend on how many cells it is made of. The most common solar panel sizes are 60-cell and 72-cell panels.
Standard Residential Solar Panels
Standard residential solar energy panels are typically 60-cell panels. These 6-cell-by-10-cell panels are approximately 5.4 by 3.25 feet or 65 by 39 inches. A 60-cell residential solar panel weighs around 40 pounds, but some panels can weigh up to 50 pounds.
A panel&#;s dimensions and weight varies by brand, so checking a manufacturer&#;s panel measurements is important to determine the exact size. Panels with a 6 by 10 grid are the most popular option for homeowners, and they offer the following ratings:
- Output: In , the standard residential solar panel&#;s output rating is 400 watts or higher.
- Efficiency: Residential solar panels typically have a 19%-22% efficiency rating.
Standard Commerical Solar Panels
In comparison, 72-cell panels are best for commercial applications. Standard commercial solar panels typically measure 6.5 by 3 feet or 80 by 40 inches on a 12-cell by 6-cell grid, and they weigh about 50 pounds.
Like residential panels, a commercial solar panel&#;s exact size depends on its specific brand. Because 72-cell panels are larger than residential panels and contain more cells, they can produce more energy. They have the following capabilities:
- Output: A commercial solar panel typically produces 400 to 500 watts, but some 72-cell panels can produce up to 580 watts.
- Efficiency: These solar panels are typically 18%-21% efficient.
Panels With Half-Cut Solar Cells
Some solar panels are made with half-cut cells, and they consist of 120 cells or 144 cells. Half-cut cells increase the amount of surface area that can convert sunlight to energy. A 120-half-cut-cell panel measures the same as a standard 60-cell residential panel, and a 144-half-cut-cell panel measures the same as a standard 72-cell commercial panel.
How to Determine How Many Solar Panels You Need
The average home or commercial building requires between 15 and 19 solar panels to make up a full solar panel system and produce adequate energy. The exact number of panels a property requires depends on the following factors:
- Energy consumption: Higher energy consumption requires more solar panels. Considering how much energy your home or business property consumes can help determine the number of panels you require.
- Energy output: A solar panel&#;s wattage output determines how much power it produces. Choosing panels with low power ratings may require you to install more panels to produce the energy your building consumes. It is best to choose panels with the highest power rating so you can rely on them to provide the electricity you need.
- Location: Location matters when determining how many solar panels you need. Homes and businesses in warmer climates typically receive more sunlight than others, allowing solar panel systems to absorb more sunlight and convert more energy with fewer panels.
- Roof position: A south-, east- or west-facing roof with minimal or no shade allows solar panels to absorb the most sunlight and produce more energy than panels facing north. South-facing roofs are the ideal location for solar panels.
How to Prepare Your Roof for Solar Panels
Because solar panels typically weigh about 50 pounds, a full solar panel system can exceed 700 pounds. While this seems like a significant weight, most residential and commercial property roofs can withstand it. However, considering your roof&#;s condition is important.
If your home or business building has an old roof, you should schedule a professional inspection. You may need to replace your roof before installing a solar panel system, and an inspector can help you determine if a new roof is necessary.
Professionals can install solar panels on any roof that is in good condition, and they can install panels on the ground if you would prefer to have a solar panel system in your yard.
Other Important Considerations
Beyond solar panel size and your roof&#;s condition, you should consider the following factors to ensure you choose the right solar panel setup and configuration:
- Panel efficiency: A panel&#;s efficiency rating determines how well it can power your home or business while saving you the most money on your energy bills.
- Output: The higher a panel&#;s output rating is, the more energy it will produce for your home.
- Brand: Choosing a reliable solar panel brand is important. Reliable solar panel brands deliver the panel efficiency and output you need, and they last longer than lower-quality brands.
- System support: Purchasing solar panels from a company offering product support provides you with easy access to repair services, upgrades and battery backup systems.

Since many people, businesses and governments have started worrying about the catastrophic effects of carbon emissions resulting in climate change. There has been an exponential increase in sustainable energy as a part of a socially conscious investment. And solar energy is amongst the most frequently cited alternate energy forms. As per Statista, the global PV capacity has increased from 5 GW () to 632 GW ().
For stakeholders, selecting the right panel is an essential stage in the development of a robust and cost-saving solar system. It all comes down to three things &#; aesthetic appeal, operational budget and energy generation efficiency. Though these are critical aspects, solar panels have a factor that is applicable to all three aspects: the type of solar panel you select.
A credible manufacturer could provide premium panels that last decades and aid you in saving a lot of energy expenses over the years. On the contrary, the manufacturers who emphasize upfront costs instead of long-term outcomes will leave you with a system that will not withstand the test of time and weather challenges.
PV panels of 1st generation are developed with mono-crystalline silicon and multi-crystalline silicon cells, accompanied by 2nd generation of thin-layer oriented solar cells (CdTe and CIGS). The PV modules of the 3rd generation strive to merge high- performance, long lifespan and thinner sheets.
When you are choosing a solar panel system for a residential, commercial and industrial installation, consider the following elements;
The color of the frame and backsheet
Every solar panel has a set of silicon cells mounted on its backsheet. This sheet reveals the spaces between cells and develops a template for the grid. Rather than conventional white, some manufacturers provide solar panels with black backsheet. Black backsheets build a more consistent panel which merges into dark roofs. Nevertheless, black retains heat, the black backsheets could become warmer than standard panels and this could degrade the efficiency of the panels.
The metal frame color across the edges of the panels also has 2 alternatives: black and silver. Panels with black frame may be more impressive but expensive. On the other hand, the performance of both frames is identical.
The size of the panels
Majority of the panels come in two different sizes: 60 cell and 72 cells. It illustrates the number of cells positioned on the solar panel. By size, 72-cell panels are a foot longer and little heavier than the 6-cell panels.
The bigger panels are favoured in the commercial and industrial installations while the 60-cell panels are preferred in sites which have space constraints. The 72-cell model is identical to the 60-cell panels, but they are economical and have greater energy output.

Panel performance
The performance of a solar panel is driven by two components &#; output rating and efficiency. Output rating is the 3-digit number written on the back of a panel and it indicates the watts of power the panel will generate under optimal circumstances. Generally, the output ratings range from 200 to 400 watts, some manufacturers offer output ratings above 450 watts as well but those panels are costly.
Further, power output isn&#;t the only aspect to watch out for. You must also recognize the percentage of panel efficiency. The more powerful a solar panel, the more KWH of electricity it will deliver per watt of capacity.
Linear Warranty and Quality assurance
A stable warranty despite the panel deterioration from the manufacturer is a significant indicator of the overall panel efficiency. Numerous top-performing solar panels are assured for 25 to 30 years and are still capable to function after their warranty ends. The energy generated is directly proportional to the money you save from the installation. And choosing modules that are supported by a complete warranty will contribute to their performance.
You would want to look at factors like panel&#;s guarantee, the reputation of the manufacturer, client feedback and operational specifications, coefficient of temperature and power resistance, to get a true panel quality measurement.
The Type of panels &#; Novergy product line
One size fit all is not an appropriate approach while choosing the panels. As it depends on a variety of variables such as your budget, the installation space, amount of energy you want to produce and lastly, the aesthetic quotient.
The information below will furnish you with the intricate details about every panel that Novergy offers. Here are the three types of panels which are designed, engineered and manufactured by us;
Best suited for sites with space constraints, Twin-cell solar panels use revolutionary technology to enhance their longevity and robustness by 2X. The traditional 72 cells are halved and 144 cells are developed. These multiple cells minimize the resistive loss and mechanical stress in the modules, which dramatically increase the module&#;s efficiency and power.
The twin-cell configuration also improves the modules&#; efficiency under reduced irradiance conditions. For example, in a rooftop situation, when some standard modules are mounted and one row of a module is shaded, the overall module performance is zero. A twin cell module guarantees at least 50% power output in a similar condition. If any parts of the module are in the shadow, the conversion will not stop. It is designed with Passivated Emitter Rear Cell (PERC) and 5-busbar technology to ensure maximum yield and faster payback.
- Building Integrated PhotoVoltaic (BIPV)
As the title indicates, BIPV can be fully incorporated with the building&#;s architecture. BIPV can be conveniently mounted on a building to replace the primary building materials while enhancing the visual appeal of the building.
