SunWize SWPB-20-C1D2-24 Solar Module

The SWPB-20-C1D2-12 is a 24 Volt 20W solar module with Class 1 Division 2 rating.

These modules are therefore perfect for power projects located near hazardous location zones, which are common in the oil & gas industry. However, they can also be used in a wide variety of applications such as telecommunications, security, traffic signage, environmental monitoring, and others. What’s more, this is a replacement for other 20 Watt modules such as the SPM020P-R, SPM020P-D, SPM020P-A, SPM020P-F, SPM020P-BP. The SWPB-20-C1D2-24 can charge 24V or 48V batteries when wired with one or two solar modules. C1D2 and UL 1703 certified.

These modules feature impact-resistant glass and heavy-duty aluminum frames. It also has three sets of mounting holes, making it a great Because of the robust design and features, this module is an excellent choice for off-grid solar power applications in harsh locations. Additionally, it features single crystalline solar cells bonded to white Tedlar backing ensuring a long life in severe environmental conditions. This solar module (SunWize Part# 020193) is an excellent alternative and replacement for the following 24V solar modules:

  • Solartech SPM020P-WP-F
  • Solarland SPL 020-24C1D2
  • Solarland SPL 030-24C1D2
