Yes, technically, you can walk on solar panels. Walking on solar panels is akin to handling any other household appliance, with a reduced risk of electrocution since solar panels, like other appliances, are UL listed.
However, despite this being possible and relatively safe, it isn’t always recommended. Walking on solar panels can induce micro-cracks in the solar cells, potentially impacting their efficiency. It’s also worth noting that solar panels are glass surfaces, which could make them quite slippery when wet.
Solar Panel Weight Resistance
Solar panels come in different types, each varying in robustness and weight resistance. For instance, a thin-film portable solar panel isn’t as tough and resistant as a standard crystalline silicon panel.
Standard PV modules feature a protective glass layer designed to withstand several forms of damage, including snow loads, impacts from dust particles, hail, and high-velocity winds from hurricanes. Most solar panels can endure a maximum weight distribution of 75 pounds per square inch (psi).
Given that the average PV module has dimensions of 65 x 39 inches (2,535 sq. in), a PV module can support around 190 pounds. This weight is slightly less than the average person’s weight, making it safe for someone to walk on the solar panel without causing damage. However, for individuals over 190 pounds, walking on a solar module is not recommended due to the higher risk of breaking the glass.
Walking on Flexible Solar Panels
Flexible solar panels are more delicate than their fixed counterparts. A slight step on a flexible solar panel could disrupt the circuits and cells. However, if you must walk on your solar panel, ensure to do so as close to the part attached to the roof as possible. This area is sturdier and can handle more pressure. If need be, distribute your weight by moving on all fours.
Risks of Walking on Solar Panels
Walking on your solar panel presents potential risks beyond just damage to the panel. Solar panels are slippery surfaces, making slips and falls a significant risk, potentially leading to severe injuries. Additionally, solar panels can become incredibly hot after long periods of direct sunlight, making them potentially harmful to any bare skin that comes into contact.
While solar panel installers occasionally walk on modules during installation, they do so skillfully, avoiding putting pressure on the glass’s middle to prevent damage. Yet, even with this expertise, the potential for damage or accidents remains.
Can a Broken Solar Panel Still Work?
If your solar panel breaks due to walking on it, it can still function, albeit not optimally. You’ll want to repair the panel as soon as possible to prevent further, potentially permanent damage to the crystalline cells.
If the warranty doesn’t cover breakage due to walking, a temporary DIY fix using polyurethane or any waterproof resin could suffice. This solution creates a thin, translucent waterproof film protecting the panel from moisture or dirt build-up. However, bear in mind that this is a temporary fix and may peel off over time.
Potential Damage from Walking on Solar Panels
Several potential damages can result from walking on solar panels. These include smudging or scratching the glass, breaking a solar cell, or breaking the busbars in-between solar cells. Each of these damages can result in significant reduction in the solar panel’s output power performance, and in some cases, a constant decrease in the entire system’s power output.
What if Your Solar Panels Break?
If you risked walking on your PV module and it broke, there are several steps you can take. First, check if your home insurance covers the damage to your solar panel. If not, the next steps would involve either repairing it professionally or replacing it.
Conclusion on Can You Walk On Solar Panels
While you can walk on solar panels and even on a solar roof, it isn’t advisable due to the potential damage to the solar panel and the potential risks to your safety. Always prioritize the use of professional services when dealing with solar panel maintenance or repair. This way, you can preserve the longevity and efficiency of your solar panels and safeguard yourself from potential harm.
Frequently Asked Questions
Q: Can you walk on a solar roof?
A: Yes, you technically can. However, it’s not advisable due to potential damage to the solar panels and the risk of personal injury.
Q: How much weight can a solar panel hold?
A: Most solar panels can hold a maximum weight distribution of 75 pounds per square inch (psi). For an average-sized solar panel, this equates to approximately 190 pounds.
Q: What happens if you break a solar panel by walking on it?
A: While a broken solar panel can still function, its efficiency will be reduced. You should aim to repair or replace the broken panel as soon as possible to prevent further damage.
Q: Can you walk on flexible solar panels?
A: Flexible solar panels are more delicate than standard ones, and even a slight step can cause significant damage. Therefore, it’s not recommended to walk on flexible solar panels.
Q: Can a cracked solar panel be fixed?
A: Yes, a cracked solar panel can be fixed, often through professional services. However, if the crack is minor and limited to the glass, DIY methods involving waterproof resin can offer a temporary solution.
