We made this availability guide to give you a sense of the solar panels that are available for purchase in 2020.
As you go through our solar panel availability guide, you will notice that most of the current availability is for PV panels built with high-efficiency, PERC, or 5BB cells. We have a pair of American made brands, and two manufacturers offer AC modules. The power range starts at the low 300W, with a few large modules reaching 400W.
American Made
Silfab
Silfab makes its solar panels in North America with a high level of precision and automation. The PERC cells used in their panels feature 5BB technology for reliable performance in any climate.
Mission Solar
Mission Solar panels are engineered and assembled in San Antonio, Texas. They qualify for ARRA and BAA programs. They are a perfect solution for government or grant-funded projects or if you prefer an American made solar panel.
High Efficiency
Panasonic
Panasonic solar panels are well known for their HIT super high-efficiency cells. HIT panels outperform the competition, making them the ideal solution when roof space is limited.
Solaria
Solaria solar panels have it all: high-performance, unmatched efficiency, and outstanding aesthetics. Look no further when those are the requirements of your next project.
Top Bankable
Trina Solar
More than 40GW of Trina Solar panels have been installed around the world, making Trina Solar a top bankable manufacturer four years in a row. Trina’s TSM-DE15H(II) 144 cell modules reach the 400W power milestone with a 19.7% panel efficiency.
Canadian Solar
With 38GW of PV panels shipped to 150 countries and a current production capacity of 10GW, BloombergNEF rated Canadian Solar as the top bankable manufacturer in 2019. The CS1H-MS all-black panels are our number one choice for residential solar systems.
