The solar energy trend is rapidly gaining traction worldwide, including in Pakistan, as the cost of solar panels and installations has decreased, making them more affordable.
As consumers seek the best solar panels, the Renewable Energy Test Center (RETC) has published its annual PV Module Index report, ranking various manufacturers based on performance, reliability, and build quality.
The PV Module Index Report is based on rigorous testing and identifies top performers in multiple categories, offering valuable insights for those involved in solar projects.
RETC, a renowned independent test lab providing certification testing for renewable energy, evaluated several factors, including back sheet ultraviolet durability, damp heat exposure, hail resistance, potential induced degradation (PID), and mechanical load tolerance.
Additionally, other conditions such as thermal cycling, UV-induced degradation, module efficiency, incidence angle modifier, LeTID resistance, resistance, and temperature coefficient were tested.
Top Solar Makers 2024
Longi, Astronergy, ES Foundry, Gstar, JA Solar, Runergy, SolarSpace, Trina Solar, and Yingli Solar were ranked among top solar panel makers.
These companies shows market-standard reliability and efficiency, making their products ideal for solar projects requiring long-term durability and high energy output.
The report further revealed that JA Solar, Longi Solar, and SolarSpace performed well in backsheet UV durability, while Trina Solarm, Astronergy, ES Foundry, Longi Solar, and Runergy also worked fine in damp heat tests.
In terms of performance, Astronergy, Mission Solar, Qcells, REC Solar, and Silfab Solar outclassed other companies. In angle modifier tests, companies like Dehui Solar, ES Foundry, JA Solar, JinkoSolar, Longi Solar, Meyer Burger, Qcells, Runergy, Silfab Solar, and SolarSpace were found to be market standard.
