Evergreen ES-A modules utilize three parallel strings of 38 cells in series giving an 18-volt peak power voltage which allows fewer strings in grid-tie systems and also provides optimum voltage for battery charging with conventional as well as MPPT charge controllers. They have Multi-Contact MC4 locking connectors and black anodized frames.

Evergreen Solar modules are designed to deliver the best performance and dependability from Evergreen Solar’s patented String Ribbon wafer technology. These modules have one of the tightest power tolerances in the industry.
Superior Performance
- Maximum power up to 5% above rated
- Anti-reflection cover glass delivers more energy
- A rigid, double-walled, deep frame with integrated water drainage holes
- Crimped frame corners – no screws to loosen
- Sealed junction box on ES-A modules never needs field maintenance
Leading Environmental Credentials
- Low lead - use of lead-free solder for all solar cell inter-connections
- Energy payback time up to 40% faster than leading crystalline technologies
- Low carbon dioxide emissions in the manufacturing process – up to 33% less than other leading crystalline technologies
