Tips For Choosing a Solar Power System Manufacturer

When choosing a solar power system manufacturer, make sure to pick one with a long track record. This way, you’ll have a better chance of the company still being in business years from now to meet any warranties that come with your purchase.

Also, make sure they use high-quality products like Panasonic. This will ensure a successful PV system that will last for many years to come.

Check Their Credibility

Most top solar panel manufacturers have gotten to their position by making a good quality product for the high volume market or by focusing on large-scale projects. This doesn’t necessarily mean they are a trustworthy company, though.

You should also verify a provider’s workmanship and performance warranties. The best companies offer 25-year warranties in each.

While rare, there are several issues that can negatively impact your solar panel’s performance. These include hot spots and minor delamination, IC discoloration, and PID (Potential-induced degradation).

Other factors that can contribute to low power output are shading, the tilt and compass direction of the array, and the quality of your wiring. You can check the insulation resistance of conductors, connections between modules and between panels and racking with a Fluke 1630-2 FC Insulation Tester. You can also check the voltage and state of charge of batteries with a Battery Analyzer. Checking these items can help you find any problems before they escalate into costly repairs.

Look for a Long Track Record

When selecting a solar power system manufacturer, you also want to ensure they have longevity. A company that has been around for many years, has a solid customer base, and provides quality products is a great choice.

It’s also important to choose a full-service solar provider that will handle every aspect of the installation process. This will help avoid any miscommunication or confusion and ensure that you are getting the best possible deal.

A good installer will design an optimized system based on your current power usage, future power needs, financial expectations, thoughts on battery storage, and environmental goals. They will also take into account local net metering policies and other incentives.

Beware of companies that quote a low price up front and then add on fees, interest charges or hidden costs later on. This is a common practice that many unscrupulous solar companies use to lure customers in. Be sure to ask if they offer product, workmanship and performance warranties as well as a power production guarantee.

Don’t Be Pressured

A number of less-than-scrupulous solar companies have been known to pressure property owners into signing a contract on the same day they meet with them. They’ll present homeowners with a “permission form,” which actually contains a legally binding contract that locks them into a solar system that they may not want.

If the solar power company you choose offers custom solutions, it’s important to take your time when deciding to make an offer. Avoid making a decision on the spot, as these pressured decisions often turn out to be more costly in the long run.

Also, be wary of companies that promise you’ll never have to pay another energy bill again. These salespeople are essentially selling you a myth, as most people who switch to solar will still be connected to the grid and will have to pay for electricity on overcast days or at night. Getting several quotes and choosing an experienced installer can help you avoid these types of unscrupulous sales tactics.

Ask Questions

In the solar industry, most companies do their best to work with reputable suppliers that are known for quality products and reliable service. A well-established solar company should be able to easily provide references and testimonials from satisfied customers. They should also be able to answer questions about their business licensing and whether they have experience working with local utility companies regarding solar energy system grid connections. If they do subcontract some of the installation work, they should be able to provide references and explain how they ensure their workers are reputable and experienced.

A good solar company should be able to help you choose the right solar panels, inverters and other components based on your priorities, such as savings over the long term, environmental sustainability or increasing the value of your home or commercial property. They should also be able to discuss features like efficiency, reliability and durability of different types of solar panels.
