If you are going to invest in a solar PV system, your excitement level may be sky-high. However, while making this purchase, make sure you don’t get carried away. Instead, you may want to focus on some important matters related to the purchase since you are going to spend quite a bit of money. Given below are some tips that may help you look for the best deal.
First of all, you must ask family members, friends, and colleagues for recommendations. Some of them may have experience buying these systems. Often, neighbors offer the best tips for buying these systems.
Their experience can help you avoid some common problems when investing in this type of power equipment. You can then avoid these problems based on their advice.
2. Manufacturer’s Warranty
Typically, manufacturers of PV panels provide guarantees. Reputable providers offer at least 25 years of warranty for the panels. The good thing is that these panels are expected to last much longer than the claimed life. So, they can pay for themselves during this period. Make sure you consider only reputable brands.
3. Price Expectations
Generally, all brands offer solar panels at similar price tags, give or take. If you have found a system that comes with a substantially lower price tag, know that there is something fishy. Inexpensive PV systems are often of poor quality. After all, you get what you pay for.
What you need to do is compare parts and warranty periods as well. Although large suppliers offer these devices at lower prices, smaller ones cut corners to reduce costs. So, this should be kept in mind.
4. Solar Panel Certifications
Certification is important regardless of the brand you are going to opt for. Usually, the certification refers to the testing type the system has gone through. For example, the test may confirm that the PV system has been tested by an independent lab. So, it helps to check the panel certifications.
5. The Type of Panels
In the past, it was a common belief that mono-crystalline panels were the best choice for limited roof space. However, this has changed as technology has advanced considerably over the past decade. It’s not a good idea to cover up your roof space with inefficient panels.
But it’s important to keep in mind that solar panels require full sunlight to produce a substantial amount of power. The output will be considerably lower in shade.
6. The Mounting System
The tracking and mounting system must be certified based on the area you live in. For instance, you must go for a cyclone-rated system if you live in an area where cyclones are quite common. Make sure that the system you need is wind certified.
In a wind storm, the mounting system must be able to withstand strong winds. Therefore, you may want to consider the wind certification and other documents.
Long story short, before you invest in a good solar power system, we suggest that you consider these factors first. This is important if you want to make an informed decision.
