Warranty pick, heavy for its output
The PV CONVENTION SERIES modules are designed for stable, predictable energy production in typical rooftop installations. Instead of unnecessary complications, they feature a proven monocrystalline structure, which handles daily operation well and facilitates equipment selection for popular inverter configurations. In practice, this means fewer surprises at commissioning and repeatable parameters for larger module batches.
Against many budget solutions, the CONVENTION SERIES stands out with its positive power tolerance and refined components responsible for safety and durability, genuinely limiting the risk of yield drops over time. For investors, a clear warranty model and the availability of aesthetic variants, including full black - important for single-family homes and premium properties - also count.
This is an excellent choice for home installations, small businesses, and commercial projects where economic viability without compromising quality and easy rooftop mounting are priorities.

EGing PV has been operating since 2003 and appears on BNEF bankable manufacturer lists, facilitating project financing through banks and investment funds. Its extensive production history reduces counterparty risk compared to newer brands.
All variants in the series carry a positive power tolerance, guaranteeing that each module delivers at least its rated Wp output. This eliminates the yield-loss risk associated with underperformance that is common with ±3% tolerance classes.
Single-glass variants come with a 25-year linear power warranty (degradation ≤0.55%/year, >84.8% retained after 25 years), while double-glass variants extend coverage to 30 years - meeting the requirements of long-payback-horizon projects such as PPAs and rooftop lease agreements.
33 power and dimension configurations simplify string sizing for inverters from SMA, Fronius, and Huawei without the need for filler modules. This is particularly valuable in retrofit projects where rooftop geometry imposes strict layout constraints.
The series includes aesthetic variants featuring a black frame and black backsheet, satisfying the requirements of premium residential customers and homeowners' associations with strict visual guidelines - a niche underserved by many budget-tier PERC modules.
The series peaks at 20.93% module efficiency, while direct peer comparables - LEDVANCE M435~455N54LB (22.77%), Sunlike Solar SKT420~455M10 (22.80%), and Solitek SOLRIF D Black (22.56%) - exceed it by 1.6-1.9 percentage points. For a 10 kWp system, this translates into approximately 7-9% more roof area required, a tangible constraint on smaller rooftops.
P-type PERC cells are susceptible to LID (Light-Induced Degradation) driven by boron-oxygen defects, with typical degradation rates of ~0.55%/year versus ~0.25-0.40%/year for N-type TOPCon. TOPCon captured approximately 65% of global module production in 2024, effectively repositioning PERC as a lower-tier technology.
An EGing module (EG-415M54-HLV) tested by PV Labs Australia on behalf of the ACT government in 2023 scored 77/100 (3rd lowest among 14 manufacturers), recording a 2.7% power loss in accelerated aging tests - more than twice the industry average of 1.3%. Although the test covered a different EGing model, the result raises questions about the brand's overall quality control.
- Module efficiency of 20.0% is 0.6pp below average for PERC 400-450W panels (median: 20.6%)
- At 200.1 W/m², this panel generates 6.1 W/m² less per unit area than PERC 400-450W median (206.2 W/m²)
- At -0.35%/°C, hot weather performance is typical for PERC 400-450W panels
- At 27.8 kg (5.8 kg above PERC 400-450W median of 22.0 kg), requires checking roof load capacity
- #12281 for efficiency, #10489 for temperature performance out of 14129 panels
