Module Versatility - 72 Cell Solar Panels
Here at SolarPanelStore.com we love versatility, which is why 72 cell solar panels are among our most popular products. In particular, a recent favorite of our team and our customers has been the Peimar SG325P 72 cell solar panel. This is a 325 Watt polycrystalline solar panel. These Italian-made solar panels are of the highest quality, low in cost, and can be used in just about every application that a solar panel can be used for! Let&#;s take a quick look at a few examples of how they can be used.
Commercial / Utility Scale Projects
Commercial and utility scale projects are high priority applications for 72 cell solar panels and Peimar actually lists the SG325P panels in their Commercial Line of products. Their low cost per watt, V Maximum System voltage and standard size and cell configuration make them a perfect fit for big power generation and outstanding equipment compatibility.

Home Grid Tie / Utility Interactive Systems
Using the same solar panel designed for huge commercial or industrial systems in a residential grid-tied system may seem&#;well wrong. But in fact, the the same benefits that apply to the commercial projects cross over to most home systems, especially if the systems are ground-mounted, or roof space limitations are not a major factor for the system size. 72 cell solar panels are typically not as &#;efficient&#; as many 60 cell solar panels which are most commonly used in home grid-tie installations, but efficiency only relates to power per square foot, not module performance. This is a common source of confusion for solar panel consumers. So if space isn&#;t a constraint, and the array generates the total watts you need, we&#;ll always recommend these lower cost-per-watt panels even with a slightly lower efficiency rating. Increasing your system&#;s ROI matters far more than panel efficiency.
Off-Grid Applications
Off-grid battery charging systems--whether remote industrial sites, tiny home or cabin power systems, or even RV applications--are great applications for these Peimar SG325P 72 cell solar panels. It might seem strange, but they work beautifully for off-grid because a 72 cell solar panel has a nominal 24 volt rating. (Pro Tip: Divide a solar panel&#;s number of cells by 3 for it's nominal battery charging voltage rating. This applies to poly or mono crystalline solar panels with standard configurations like 36, 60, and 72 cell panels.) Nearly all off-grid systems will have nominal voltage of 12V, 24V, or 48V. In 12V systems, the panel&#;s voltage does need to be stepped down with an MPPT charge controller. The MPPT controllers are also more efficient, but are more expensive than a standard PWM controller. On the other hand, the cost per watt of a 72 cell solar panel like the Peimar SG325P is usually cheaper than most 36 cell (12V nominal) panels&#;which can make the overall off-grid system cheaper than using 12V panels.
At SolarPanelStore.com we have a ton of experience with all of these types of systems and are eager to help our customers find solutions that often exceed their expectations, so please don't hesitate to give us a call with any questions or quotes for systems that you are working on or researching!
If you're looking to switch to solar, you may wonder if you have enough space to install the panels. This is a valid concern - solar panels are pretty big! Most home solar panels are about 5.5 feet x 3 feet and weigh roughly 40 pounds each.
Most of the time, you won't see the size of solar panels expressed in feet. Instead, you'll see it's listed as the number of solar cells within a panel, with the most common solar panel sizes being 60-cell and 72-cell.
Let's take a closer look at the difference between these solar panel sizes and how to pick the right one for your home.
Calculate the costs and benefits of installing solar on your homeWhen you look at a solar panel, you&#;ll see it&#;s made up of small squares. Those squares are called solar cells, and they're the part of the panels that turn sunlight into electricity.
You'll see the size of a solar panel described by how many cells it has. 60-cell panels are usually laid out in a 6 by 10 grid and are the most popular option for home solar installations. You&#;ll typically find that 60-cell solar panels have output ratings between 350 and 400 watts and efficiency ratings between 17% and 19%.
72-cell panels, on the other hand, are usually arranged in a 6-cell by 12-cell grid. Because 72-cell panels hold more cells, they are bigger and can produce more solar power, making them popular for commercial installations. 72-cell panel wattage usually sits around 415 to 450 watts, but they can get into the 460-watt range. Their efficiency ratings are typically between 18% and 21%.
Many people want to know the physical size of solar panels, not just how many cells the hold. The average 60-cell solar panel is about 65 inches by 39 inches, or 5.4 feet by 3.25 feet, and weighs around 40 to 50 pounds. The actual dimensions will vary from panel to panel, so we&#;ve listed a few for some of the most popular 60-cell panels on the market:
72-cell panels are larger, about 80 inches by 40 inches and about 1.5 inches tall. This works out to just about 6.5 feet by 3 feet for 72 cell panels, give or take a few inches. 72-cell modules generally weigh around 50 pounds. Here are the dimensions for 72-cell panels offered by top brands:
Here&#;s a brief breakdown of the pros and cons of each panel size.
&#;How many solar panels do I need to power my home?&#;; the age-old question with absolutely no easy answer. Based on the U.S.'s average energy consumption and sunlight, a residential solar system needs between 15 and 19 solar panels, which will require around 260 to 340 square feet of roof space.
The actual number of solar panels your specific home needs will depend on various factors like:
The amount of energy you use: The more solar panels you have on your roof, the more power they will produce. If your electricity usage is higher than your neighbor, your solar systems will vary in size because you will need more panels to cover your extra energy use.
Sunlight available: If you live in sunny Arizona, your solar panel system can produce more power than panels on a roof in Illinois.

Panel output: Solar panels with higher power ratings, or wattages, can produce more electricity. Using high-wattage panels, you can install fewer panels to meet your energy usage and eliminate your utility bill.
When you work with a solar installer to find the perfect number of panels to provide solar energy for your home.
Once solar panels are installed on your roof, you don&#;t have to think much about their size anymore.
But, with portable off-grid panels, solar panel size is one of the most important things to consider. Your RV might only have a small amount of roof space, or you might want something you can carry around and set up outside your campsite!
Because portable solar panels are made for travel, they tend to be smaller and have about 40 cells as opposed to 60. 200-watt portable panels are around 5 feet by 2 feet.
You could also opt for flexible solar panels, which also measure about 5 feet by 2 feet. But flexible panels can bend and are much thinner than crystalline panels, so they&#;re easier for storage.
The flexible panel sold by Renogy, a popular portable solar brand, has 72 cells, but they&#;re smaller than the ones used in typical commercial panels. The panel is also substantially lighter, weighing just 10.8 pounds!
Folding solar panel kits are also an option for portable use. Foldable panels can be small enough to fit in your backpack, or large enough to power your RV - there's a wide range of options out there.
There are many factors that you should consider before the size of your solar panels, like solar panel efficiency and solar panel warranties.
Solar panel efficiency is the percentage of light that strikes the surface of a panel that is converted into usable electricity. Modern solar panels have efficiencies that range from around 17% up to 22.8% in some premium models.
Highly efficient panels take up less space, which will allow you to fit more panels on your roof.
There are two types of warranties that cover solar panels.
The first is the product warranty. This is the period during which you can ask the manufacturer to replace the solar panel should any problem arise. Nowadays, a product warranty of 12 years is standard, but more brands are starting to offer product warranties of 25 years.
The second type of warranty is a performance guarantee. Most mainstream panels have a 25-year production warranty, guaranteeing the panel will produce a certain level of output at every stage of the panel&#;s life. From the date your panels are installed up until the 25-year mark, the minimum guaranteed output of your panels will gradually decrease.
You can expect an output of close to 100% for year one, gradually down to between 80 and 92 percent for year 25. This loss in output is technically known as solar panel degradation. Some solar panel manufacturers, such as Canadian Solar, even offer a 30-year performance warranty on certain panel models.
Find out if solar panels are worth it for your homeThe easiest way for homeowners to figure out the best solar panel size for their needs is to work with a dedicated solar installer. Solar installers will size your system based on your energy needs, coupled with your available roof space and the sunlight in your area. They can recommend a system size that can fit on your roof and reduce or eliminate your electric bill.
