The Delta SM series solar modules are manufactured from high efficiency solar
cells of Grade A quality class, which guarantees high performance, durability and
reliability. The strength of the modules is provided by the use of a tempered glass
and an anodized aluminum profile frame (with drainage holes). Exclusive module’s
frame prevents its deformation under extreme weather conditions.

Quality and warranty
- The quality control complies with IEC61215 and IEC61730 standards.
- The warranty for solar module is 10 years and does not cover any damages caused by mechanical, thermal or other external actions.
- The manufacturer guarantees that more than 90% of the declared nominal power will be retained for 10 years. 80% of the declared minimum nominal power will be retained for 25 years.
ATTENTION! The solar module should be installed and connected by a qualified technician with the corresponding access level. While connecting the solar module, strictly
observe the connection polarity. Be sure to use a solar charge controller to charge the battery and power the load. Before using the module, read the manual carefully.
