Then there is the technology itself, the panels, inverters and racking, the physical components that transform homeowners from consumers to producers. Your solar panel uses photovoltaic cells to capture light and convert it into electric power. There are hundreds of Photovoltaic (PV) manufacturers. Some are giant electronic manufacturers that make everything from smartphones and refrigerators to solar panels. Many of these have recently entered the market because of the increasing demand for solar power.
Then there is the established research- and science-based solar companies bringing innovation and durability to the market. Mass produced panels manufactured with price point as the key feature offer only limited warranties and are often categorized as Conventional (or Standard) Efficiency panels. Panels from the older, technology based companies offer greater reliability and production due to scientific research, testing and customer feedback collected over decades. These panels are considered Premium (or High Efficiency) Panels and their pricing reflect the consumer’s preference for performance and time-tested reliability. Premium panels are easily recognizable; they are the panels that have all-inclusive warranties (labor & shipping included) and offer a performance warranty over 85% stated production at 25 years.
It is worth it to consider premium panels even if you are attempting to save as much as possible upfront. They produce more power now and over time. Aesthetics are considered better on some of the high end panels’ better grade of materials and even all black modules are used with low profile racking systems. Looking good is important! As the residential solar market continues to mature quality makes a greater impact both for power production and at resale of the property. Quality and reliability come under scrutiny when prospective buyers are involved since they will most likely be the ones to use the warranty.
