  • How Much Weight Can a Solar Panel Hold?

    Solar panels on the roof

    Standard PV modules, which typically feature a glass top, can withstand additional loads from snow, hail, and even the strong winds from hurricanes—without breaking. They can hold weights that generally correspond to around 20 to 50 pounds per square foot (psf).

    However, this doesn't mean you should walk on solar panels without risking damage. You could still scratch or crack them by applying uneven pressure or stepping on vulnerable areas, even if you weigh less than the panel's maximum load capacity. Moreover, walking on solar panels might void their warranty or diminish their efficiency.

    It's also crucial to recognize that there are various types of solar panels, and not every module is constructed with the same level of durability. For instance, bendable CIGS thin-film solar panels and fiberglass solar panels can hold much more weight than rigid glass Monocrystalline solar panels due to their sturdier and tougher construction.

    Is It Safe to Walk on Solar Panels?

    The short answer is no. Walking on solar panels is not safe for you or your panels. Here are some of the reasons:

    • You may slip and fall. Solar panels are smooth and slippery, especially when wet or dusty. If you lose your balance and fall from your roof, you can get injured or damage your property.

    • You can electrocute yourself. Solar panels produce electricity when exposed to sunlight. If you touch any exposed wires or connectors while walking on them, you can get a shock or start a fire.

    • You can damage the wiring or mounting system. Solar panels are connected by wires and attached to your roof by racks and bolts. If you step on these components, you may loosen or break them, affecting the stability and performance of your system.

    • You can create hot spots. Solar panels work best when they receive uniform sunlight across their surface. If you block or shade any part of them with your body or feet, you can create hot spots that reduce their output and lifespan.

    Although you may have seen some solar panel installers carefully walking on the solar modules during installation, skillfully avoiding pressure on the center of the glass to prevent damage to it or the solar cells, there is a risk of cracking the solar panel glass and damaging the modules.

    What Happens When You Walk on Solar Panels?

    When you walk on solar panels, you risk damaging or reducing the solar panel efficiency in several ways. Here are some common damages that will occur caused by walking on the solar panels: 

    • Scratching or Breaking the Solar Panels 

    Walking on solar panels can cause scratches or cracks, especially if excessive pressure is placed on their fragile glass. If the solar panels have severe scratches and breaks, they will suffer up to a 15% efficiency loss, reduced power output, and vulnerability to moisture and debris. In this case, they may need to be repaired or replaced by a technician to regain panel efficiency.

    • Cracking Solar Cells

    If you apply too much weight to your PV module, you might break a solar panel cell. Broken solar cells can result in reduced voltage and power output.

    Additionally, without optimizers or microinverters, this decrease in performance could affect the entire system's energy generation and delivery. Consequently, you may need to replace the broken solar panel.

    • Busbars In-Between Solar Cells Breaks

    Busbars facilitate the flow of electrical current between cells within solar panels. Damaged busbars can significantly impair a PV system's performance. A single broken busbar may lead to overheating, while multiple breaks can result in a complete disconnection of the entire string. 

    Imagine this: If you're living off-grid and the busbars in your solar panels break due to excessive weight, you could be without electricity for several days until the problem is fixed. That would be painful!

    • Solar Panel Delamination

    Solar panels are crafted using layers of materials that are bonded together with adhesives. If you bend or twist them, for instance by walking on them, you might cause these layers to separate, or delaminate. Delamination can potentially lead to reduced performance, moisture ingress, overheating, and even electrical hazards.

    What to Do if Your Solar Panels Break?

    If your PV solar module breaks due to walking on it or for any other reason, here are some steps you can follow:

    1. Turn Off Your System

    First, disconnect your system from the grid and turn off the inverter and breaker. This will help prevent further damage or safety hazards, such as fire risks.

    2. Contact Your Installer or Manufacturer

    Next, contact the company that installed or manufactured your solar panels. They can assess the extent of the damage and advise you on the best course of action.

    Depending on the warranty and insurance policy of your system, they may be able to repair or replace your broken panels for free or at a reduced cost. For instance, at, we offer a 12-year warranty on our rigid Monocrystalline solar panels for homes and RVs.

    3. Repair or Replace the Solar Panels

    If your insurance doesn't cover the expenses, you'll need to have the module repaired by a professional or, if it's beyond repair, replace it with a new one.

    4. Clean up the Debris

    Finally, carefully clean up any glass or metal fragments that may have fallen from your roof. These could pose risks to people, animals, or vehicles passing by.
