Are LONGi solar panels best for you? How to choose the right solar panels for your needs
EnergySage has classified all types of solar equipment into an easy-to-understand framework. The EnergySage classification system incorporates technical specifications for solar panels, inverters and batteries to compare their performance, durability, warranty and overall quality. By assessing each product across a range of metrics, the EnergySage rating system groups equipment into five different classifications:
Excellent solar panels
Solar panels earning the Excellent rating are ideal for maximizing the performance of your solar energy system. Excellent panels produce more electricity over a smaller area and last longer than other panels, though they may come at a price premium. You’ll likely pay a higher upfront price for the exceptional performance, quality, durability, and warranty coverage of Excellent solar equipment.
Very Good solar panels
Solar panels earning the Very Good rating perform above average across a range of criteria, and may only miss out on the highest ranking due to a shorter warranty, lower efficiency, or decreased performance under sub-standard conditions. You can expect strong performance and slightly lower costs than associated with Excellent solar panels.
Good solar panels
Solar panels earning a Good rating are a safe and solid choice for your solar energy system under most circumstances. These panels are in the average range for most or all technical criteria analyzed, though may offer a shorter-than-average warranty. Good solar equipment is ideal for solar shoppers seeking a bargain for their solar energy system.
Fair solar panels
Solar panels receiving a Fair rating are at the low end of what is available for solar equipment today. This equipment may be older, no longer produced by manufacturers and likely rarely stocked by solar installation companies. Fair solar panels may have received a higher rating during previous iterations of this rating system, but now has dropped in quality as the technology available across the rest of the industry has improved.
Poor solar panels
Solar panels receiving a Poor rating are at the bottom end of the spectrum of solar equipment, and should be priced accordingly if at all available. These panels has been surpassed by advances in technology and performance of other equipment available in the industry.
Unrated solar panels
Solar panels are listed as Unrated if their technical specifications sheet does not include information necessary for the rating system.
