How Much Do Solar Panels Weigh?
A typical 60-cell panel weighs about 40 pounds. When looking into a solar panel system and considering how much a solar panel weighs, you should also look into the solar panel type. There are 3 popular types of solar panels. The types of residential solar panels on the market today are Monocrystalline panels, Polycrystalline panels, and Thin Film panels. Larger panels, like 72-cell panels or 96-cell panels, will weigh more, impacting the solar panel installation process.
Weight of Different Types of Solar Panels
- Monocrystalline Solar Panels
- Average Weight: 40-50 pounds per panel (18-23 kg)
- Weight per Square Foot: Approximately 2.5-3 pounds (1.1-1.4 kg)
- Polycrystalline Solar Panels
- Average Weight: 42-52 pounds per panel (19-24 kg)
- Weight per Square Foot: Approximately 2.6-3.1 pounds (1.2-1.5 kg)
- Thin-Film Solar Panels
- Average Weight: 25-35 pounds per panel (11-16 kg)
- Weight per Square Foot: Approximately 1-1.5 pounds (0.5-0.7 kg)

Can Your Roof Handle the Weight of Solar Panels?
When considering whether your roof can handle solar panels, it’s important to understand that the weight added by a typical solar panel system is generally much less than what many people assume. On average, solar panels weigh around 40 to 50 pounds per panel, and while this does add some weight to your roof, it’s usually not enough to cause any issues for most residential roofs. Whether your roof is pitched or flat, the additional weight is typically well within the limits of what the structure can support, provided it is in good condition and has not experienced significant wear or damage.
However, it’s always best to approach this question with caution. A roof’s structural integrity is crucial when installing solar panels, especially since the system will be exposed to external forces like wind, snow, and rain over time. This is why it’s highly recommended to have a professional structural engineer assess your roof before proceeding with installing solar panels. The engineer will be able to evaluate your roof’s age, condition, materials, and overall load-bearing capacity. If the roof is suitable for solar panel installation, the engineer will provide you with a certified letter stating that it can safely bear the additional weight.
In some cases, however, the engineer may determine that your roof is not quite up to the task. If that happens, they will provide you with an assessment that details the necessary modifications or reinforcements needed to ensure the roof can safely handle the solar system. These modifications could include adding additional support beams, reinforcing roof trusses, or even replacing sections of the roof if it’s too old or damaged. By addressing these structural issues early, you can avoid potential complications down the road and ensure that your solar system remains secure and effective for years to come.
Are Solar Panels Heavy on a Roof?
- No, the solar panel’s weight is not significant enough to impact your roof. Most homes have roofs built to support a much heavier infrastructure than solar panels. Residential solar panels weigh about 40lbs.
One thing to consider is the style of roof you have. If your home has a pitched or angled roof, the weight of solar panels may be less than those on a flat roof. The average weight of solar panels on a pitched roof is about an additional 2.5 pounds per square foot. For flat roofs, they add about 5 pounds per square foot. This is an important factor when evaluating the energy consumption of your solar setup and ensuring you have the available space for installation.

What Makes Solar Panels So Heavy?
The question of how heavy are solar panels stems from the aluminum framing and tempered glass used to create the panels. The number of cells in each panel impacts its weight, with single-crystal panels generally being lighter than high-efficiency polycrystalline ones. The semiconductor component of the cell is usually made of silicon. This means that each part of the panel that generates electricity weighs only a few hundred grams! Although tempered glass is heavier than normal glass, it is the industry standard for solar panels. This glass needs to withstand the impact of a 1-inch diameter hail traveling at 50 miles per hour. This means your solar panels will outlast the extreme weather your roof endures.

How Much Do Solar Panels Weigh FAQ
Q: How Much Do Solar Panels Weight Per Square Foot?
A: Residental solar panels weigh about 40 pounds That means, for pitched roofs, solar panels add about 2.8 pounds per square foot. For flat roofs, they add about five pounds per square foot. The total weight will depend on how many solar panels you plan to install.
Q: How Much Does a Single Solar Panel Weigh?
A: You can expect a single solar panel to weigh about 40 pounds. This is specifically for residential solar systems. If you’re looking into commercial installations, you can expect one to weigh about 50.
Q: What are Tesla Solar Panels?
A: Instead of using panels, the Tesla Solar Roof turns your entire roof into your solar array. The Tesla solar roof uses tempered glass panels that replace your standard shingles, providing the same protection you’d expect from a traditional roof while also capturing solar energy.
