One of the most important things to consider when hiring a solar contractor is their experience. Make sure to ask how long they have been in business and how many solar projects they have completed. It’s also a good idea to ask for references from previous clients. Another important factor to consider is the solar contractor’s warranty. This will protect you in case something goes wrong with the solar installation.
However, if you’re not sure if the contractors did a decent job or not, there are several telltale indicators that can help you.
If the panels are yellowish
Solar panel systems produce electricity for many years with little maintenance required. However, solar panels can degrade over time due to several factors, including exposure to UV light and extreme temperatures. One type of solar panel degradation is EVA degradation. This occurs when the clear encapsulant that covers the solar cells becomes yellow or brown.

Hotspots are areas of the solar panel that experience higher temperatures than the surrounding area. They can also cause EVA degradation. Hotspots are more likely to occur in solar panels with poor quality construction. Moreover, they can severely reduce the lifespan of the panel. If you notice any staining on your solar panels, contact a solar contractor. They can assess the damage and determine whether the panel needs a replacement.
If the system has rust and marks that make it appear unattractive
If you see any solar panels that are unattractive or have unsafe tilt frames, rust stains, or fractures, notify your solar contractor ASAP. If your solar contractor finds any damage, they can advise you on the best course of action to ensure that your solar panels continue to operate efficiently. By keeping an eye out for potential problems, you can help to ensure that your solar investment continues to pay off for years to come.
If the panels are too close to the edge of the roof
Under no circumstances should solar panels extend over the edges of your roof unless a structural engineer grants an engineering certificate. This is because wind can get underneath the panels and weaken the fixtures. Another reason is that rainwater can fly over your gutter, causing serious damage.
Poor shading and location of the system
solar panels work best when there is no shade cast upon them whatsoever. If one panel in a group is completely shaded, it can poorly affect the output of the entire system. Moreover, it may not look pleasant on the roof if they have not installed the panels neatly. The solar contractor you have hired should be well versed enough in solar panel installation to avoid any shading issues that could arise. If your solar contractor is truly qualified, they will also be able to advise you on the best way to position your solar panels for optimal results.
If the wiring is visible and dangerous the solar
If you have solar panels installed on your roof, it is important to make sure that your cabling is properly protected. Exposed cable is vulnerable to damage from the weather and scrapes against the roof surface. This can cause damage to the wire’s protective coating, which can lead to electrical shorts and fires. Exposed cabling is not only unsightly, but it is also a major safety threat. If you are concerned about the condition of your solar panel cabling, contact a solar contractor for an inspection. They should be able to tell you if your cabling needs to be repaired or replaced. Also, do not forget to make sure they are experienced. Make sure you ask the right questions before hiring them to know if they are the ones.
To ensure that your solar investment is worth it, make sure you hire the right contractor. A poor job can cost more in repairs or even mean lost opportunities for future projects so don’t take any risks with quality.
