As of February 2015, the top three solar panel systems recommended by LiveScience.com. are the Kyocera KD315GX-LPB, Canadian Solar CS6X-305M and Grape Solar 390W. These panels all show a solar efficiency rate between 15 and 16 percent.
The Kyocera KD315GX-LPB solar panel system is known for its high rate of solar efficiency, which is a panel's ability to convert sunlight to energy per each unit of surface area. At 16 percent, this system is at least 2 percent more efficient than many other silicon-based solar cells. The Kyocera KD315GX-LPB is easy to maintain and clean and comes well equipped to deal with the elements.
The Canadian Solar CS6X-305M solar panel system comes highly recommended by experts due to its convenient rectangular shape and 15.9 solar efficiency percentage. This system is very durable and is guaranteed to provide 90 percent output for the first year of use and 80 percent for the next 25 years.
The Grape Solar 390W solar panel system operates with a solar efficiency percentage of 15.21. This system doesn't require soap for cleaning with soap and can withstand 50 pounds worth of snow per square foot. Grape Solar's customer service department is also top rated. Customers can quickly reach technicians for troubleshooting questions either on the phone or via email.
