Compare GL Solar panels on ComparePV." source: "https://comparepv.com/reviews/gl-solar" --- # GL Solar panels, *read off the datasheets* GL Solar Energy s.r.l. is a small Italian company based in Marcianise (Caserta) specializing in the design, production, and installation of photovoltaic systems for residential and industrial applications. The company also distributes solar panels and related equipment, working with major international brands... Everything below is computed from those 13 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where GL Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2000 - **Headquarters:** Marcianise, Italy - **Employees:** 1-10 Company facts, not datasheet figures. Tier 1 is a financier's bankability list, and says nothing about how a panel performs. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 13 | models in the database | | Average efficiency | 22.6 % | across the catalogue | | Best efficiency | 23.6 % (good) | their strongest module | | Power range | 465-640 Wp | smallest to largest | | Bifacial share | 100 % | 13 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of GL Solar's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof. ### Most efficient module efficiency | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [HY-NT10/72GDF-610W](https://comparepv.com/panel/gl-solar-hy-nt10-72gdf-610w) | 610 Wp | 23.6% (good) | | 2 | [HY-NT10/72GDF-605W](https://comparepv.com/panel/gl-solar-hy-nt10-72gdf-605w) | 605 Wp | 23.4% (good) | | 3 | [HY-NT10/54GDF](https://comparepv.com/panel/gl-solar-hy-nt10-54gdf) | 465 Wp | 23.3% (good) | | 4 | [HY-NT10/72GDF-600W](https://comparepv.com/panel/gl-solar-hy-nt10-72gdf-600w) | 600 Wp | 23.2% (good) | | 5 | [HY-NT10/72GDF-595W](https://comparepv.com/panel/gl-solar-hy-nt10-72gdf-595w) | 595 Wp | 23.0% (good) | - HY-NT10/72GDF-610W - Monocrystalline bifacial - HY-NT10/72GDF-605W - Monocrystalline bifacial - HY-NT10/54GDF - Monocrystalline bifacial - HY-NT10/72GDF-600W - Monocrystalline bifacial - HY-NT10/72GDF-595W - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/gl-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [3SHBGH-C#-640](https://comparepv.com/panel/gl-solar-3shbgh-c-640) | 22.6% (good) | 640 Wp | | 2 | [3SHBGH-C#-635](https://comparepv.com/panel/gl-solar-3shbgh-c-635) | 22.4% (good) | 635 Wp | | 3 | [3SHBGH-C#-630](https://comparepv.com/panel/gl-solar-3shbgh-c-630) | 22.3% (good) | 630 Wp | | 4 | [3SHBGH-C#-625](https://comparepv.com/panel/gl-solar-3shbgh-c-625) | 22.1% (good) | 625 Wp | | 5 | [3SHBGH-C#-620](https://comparepv.com/panel/gl-solar-3shbgh-c-620) | 21.9% | 620 Wp | - 3SHBGH-C#-640 - Monocrystalline bifacial - 3SHBGH-C#-635 - Monocrystalline bifacial - 3SHBGH-C#-630 - Monocrystalline bifacial - 3SHBGH-C#-625 - Monocrystalline bifacial - 3SHBGH-C#-620 - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/gl-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 13 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one.
