What You Need to Know About Solar Panel Ratings

Ready to make the switch and invest in quality solar panels for your Scottsdale, AZ home? You’re in good company—many homeowners see major benefits when they upgrade to solar. Not only does it reduce your carbon footprint, but it also reduces your monthly energy bills and even increases the value of your home.

Solar panels aren’t created equal, though, and there are differing levels of quality and power ratings that you need to know about before you make a purchase. Here’s what you need to know about the various ratings for solar panels before you invest in solar energy systems in Scottsdale, AZ.

How can I select the right solar panels for my needs?

Investing in solar energy systems is a big deal, but it’s a feature that adds value to your home, reduces your carbon footprint and saves you money in the long run. Here are four things to keep in mind during your search:

  • Power ratings: Most residential and commercial solar panels in Scottsdale, AZ have power ratings from 250 to 400 watts. The higher the rating, the more power the panels produce. Keep in mind that the rating reflects power output under ideal conditions—in other words, a full day’s charge under the sun.
  • Power tolerance: There’s always some difference between the power rating and the actual power output of a panel. This number is shown as a percentage. It’s best to choose an option with a narrow power tolerance, since you’ll have more consistency that you can rely on.
  • Panel efficiency: The higher the efficiency, the better your panels will be able to convert the sun’s rays into usable energy. High-efficiency panels generate more energy than a panel of the same size with lower efficiency. This is especially important if you only have a small space in which to put your panels.
  • Temperature coefficient: High heat can reduce a panel’s efficiency. Panels that have less sensitive temperature coefficients perform much better in the long run and are well worth the investment. Look for the lowest temperature coefficient you can get.

Are there any specific brands that provide excellent quality?

There are many different solar panel brands on the market with varying levels of quality. While all manufacturers need to follow International Organization for Standardization (ISO) quality assurance standards, there are some manufacturers who go above and beyond in terms of technology and durability.

One of these is LG. LG solar panels provide excellent performance with super high efficiency. They also have great warranties and low temperature coefficients. Their bifacial models use special Cello Technology to absorb sunlight from both above and below the panel to improve efficiency and soak up as much energy as possible from the sun’s rays. Look for a preferred LG installer to provide you with this high-efficiency, cost-saving system.

Choosing quality solar energy systems in Scottsdale, AZ can make all the difference in the amount of money you can save when you make the switch to solar. Investing in a premium brand can pay dividends in the long run.
