Below are some of the most common solar panel testing standards and certifications to look for when comparing solar panels: The IEC is a nonprofit that establishes international assessment standards for a bunch of electronic devices, including photovoltaic (PV) panels.
Like other types of electronics, solar panel modules go through rigorous testing before installation. These tests are critical to determining the quality and performance of panels under particular environmental stresses, as well as confirming they meet mandated safety requirements.
Solar panel performance testing occurs in fixed laboratory conditions, known as Standard Test Conditions (STC). Because these conditions are consistent across the industry, you can compare performance metrics (such as power rating, module efficiency, optimal voltage, etc.) between different solar panels.
Importantly, the IEC does not test or certify panels themselves – they establish the standards for other testing facilities to adhere to when evaluating solar panel quality. IEC 61215 is one of the core testing standards for residential solar panels.
If a solar panel module successfully meets IEC 61215 standards, that means it completed a number of stress tests and performed well in regards to quality, performance, and safety. IEC 61215 standards apply to both monocrystalline and polycrystalline PV modules, which are the most common types of solar panels.
The performance PV standards described in this article, namely IEC 61215 (Ed. 2 – 2005) and IEC 61646 (Ed.2 – 2008), set specific test sequences, conditions and requirements for the design qualification of a PV module.

The Toolbox for Renewable Energy Project Development's Solar Power Use Claims Guidance page helps electricity consumers understand the legal right that RECs offer their owners when making solar power use claims and provides resources for making claims.
If you own your solar system, you can claim to be using the solar power as long as you have not 1) sold the RECs to another party, or 2) entered into any contractual agreements that sell or transfer the RECs or the environmental attributes to another party.
These issues often lead to customer complaints and legal claims and are a major liability risk for solar companies. Unlike delays that can be easily resolved with offers of compensation, safety hazards or roof damage caused during installation can infuriate homeowners, and rightly so.
Here are a few potential outcomes: If the court determines that your solar company is indeed liable for the issues you've experienced, they may award you compensation to cover the costs of any damages you've incurred. This can include repair costs, property damage, and any financial losses resulting from the solar installation.
This leads to frustration, complaints to consumer protection agencies, or legal disputes over alleged misrepresentation or breach of contract. Example: A customer signs a contract with a solar company after being told the system will cost $65,000.
This can include documents such as your solar energy contract, photographs of any damage, correspondence with the solar company, and any other relevant information. While you may be able to handle a small claim on your own, it's generally advisable to hire a lawyer who specializes in solar energy litigation.
If your solar company fails to properly install the system or causes damage during the installation process, you may be able to take legal action to seek compensation for repairs or other damages.

Roof leaks after solar panel installation are usually due to one of three main reasons:Faulty Installation: Poor installation practices are the most common cause of leaks. Incompatible Roof: Some roofs are not suitable for solar panel installations.
The installation of solar panels on your roof can be an exciting time as it means you will be cutting down your energy costs considerably, but doing this will involve drilling holes in your roof, which could beg the question of whether this will cause your roof to leak? There are various reasons your roof could leak after installing solar panels.
If you're experiencing roof leaks after installing solar panels, contact a professional roofing contractor who specializes in solar panel installations for a thorough inspection. They can identify the source of the leaks and recommend appropriate solutions.
Overall, while solar panels themselves do not cause leaks, these common issues can arise depending on roof type and installation. Before installing solar panels, it's important to have a professional roof inspection rather than attempting a DIY approach.
In our Rent-to-Own solar plans, GetSolar covers all out-of-pocket expenses for your rooftop solar system across the lifetime of your agreement, including any roof leakage that might occur as a result of our installations.
Exposure to weather conditions and UV radiation over time can cause sealants to degrade, leading to gaps that allow water to infiltrate and cause a post-solar panel leak. Regular inspection and maintenance of the sealants can help prevent this issue. Roof age and condition also impact the risk of a post-solar panel leak.
There could be any number of causes for a leak, including damage caused by walking on the roof, dragging solar panels, or having a tile break in the underlayment. These are not issues you can resolve yourself, and since your warranty would cover these issues, your first call should be to your installer.
We have a solar hot water panel and one of the pipes coming from it seems to be leaking an oil-like substance, presumably thermal transfer fluid. The pressure gauge is showing zero bar, so once it's fixed it will likely need topped up.
We have a solar hot water panel and one of the pipes coming from it seems to be leaking an oil-like substance, presumablythermal transfer fluid. The pressure gauge is showing zero bar, so once it's fixed it will likely need topped up. The leak is coming from a specific joint in the pipework, where the flexible pipe meets the fixed pipework.
If you've noticed water leaking from your solar tube, there are a few possible explanations. First, check to see if the leak is coming from the top or bottom of the tube. If it's coming from the top, it could be due to condensation. This is especially common in humid climates. To fix this problem, simply wipe away the water as needed.
Fluid Leaking One of the common and significant issues of solar water heaters that you would face is fluid leakage. This problem generally occurs when system components like pipes, temperature, and pressure relief valves are damaged. Another likely reason for fluid leakage in the water heater could be the loose fitting of the pipes and valves.
Solar tubes are a type of solar energy system. They are typically used to heat water or to produce electricity. Solar tubes are not known to cause roof leaks. How Do You Repair a Solar Tube? Solar tube skylights are a great way to add natural light to your home, but like any other type of skylight, they can develop leaks over time.
One of the main causes of this issue is the broken glass of the solar panel. Damaged solar panels can cause solar collectors to be ineffective in catching the maximum solar energy. When you notice a solar panel leakage, the probable cause could be a pipe burst due to freezing or extreme pressure within the system.
Solar tube skylights are a great way to add natural light to your home, but like any other type of skylight, they can develop leaks over time. If you've noticed a leak in your solar tube, don't despair – there are ways to fix it! To start, you'll need to locate the source of the leak.
