Compare Gintech panels on ComparePV." source: "https://comparepv.com/reviews/gintech" --- # Gintech panels, *read off the datasheets* Gintech Energy Corporation was a Taiwanese manufacturer of crystalline silicon solar cells and modules, founded in 2005 and headquartered in Zhunan, Hsinchu Science Park. The company produced mono- and multi-crystalline solar cells under its Diamond, Douro, and Phoenix product lines. In January... Everything below is computed from those 7 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Gintech does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2005 - **Headquarters:** Zhunan (Hsinchu Science Park), Taiwan - **Employees:** 1000-2000 - **Listed:** TWSE: 3514 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 | 7 | models in the database | | Average efficiency | 16.6 % | across the catalogue | | Best efficiency | 18.8 % | their strongest module | | Power range | 255-365 Wp | smallest to largest | | Bifacial share | 0 % | 0 dual-sided models | | Average warranty | 25 years | guaranteed output term | ## 01. The top of the range The leaders of Gintech'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 | [GIN M6F-72](https://comparepv.com/panel/gintech-gin-m6f-72) | 365 Wp | 18.8% | | 2 | [GIN P6F-60-280W](https://comparepv.com/panel/gintech-gin-p6f-60-280w) | 280 Wp | 17.0% | | 3 | [GIN P6F-60-275W](https://comparepv.com/panel/gintech-gin-p6f-60-275w) | 275 Wp | 16.7% | | 4 | [GIN P6F-60-270W](https://comparepv.com/panel/gintech-gin-p6f-60-270w) | 270 Wp | 16.4% | | 5 | [GIN P6F-60-265W](https://comparepv.com/panel/gintech-gin-p6f-60-265w) | 265 Wp | 16.1% | - GIN M6F-72 - Monocrystalline - GIN P6F-60-280W - Polycrystalline - GIN P6F-60-275W - Polycrystalline - GIN P6F-60-270W - Polycrystalline - GIN P6F-60-265W - Polycrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/gintech?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [GIN M6F-72](https://comparepv.com/panel/gintech-gin-m6f-72) | 18.8% | 365 Wp | | 2 | [GIN P6F-60-280W](https://comparepv.com/panel/gintech-gin-p6f-60-280w) | 17.0% | 280 Wp | | 3 | [GIN P6F-60-275W](https://comparepv.com/panel/gintech-gin-p6f-60-275w) | 16.7% | 275 Wp | | 4 | [GIN P6F-60-270W](https://comparepv.com/panel/gintech-gin-p6f-60-270w) | 16.4% | 270 Wp | | 5 | [GIN P6F-60-265W](https://comparepv.com/panel/gintech-gin-p6f-60-265w) | 16.1% | 265 Wp | - GIN M6F-72 - Monocrystalline - GIN P6F-60-280W - Polycrystalline - GIN P6F-60-275W - Polycrystalline - GIN P6F-60-270W - Polycrystalline - GIN P6F-60-265W - Polycrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/gintech?sort_by=power&sort_order=desc) ## 02. What the catalogue is made of Shares are of the 7 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. [Cell technology across the market](https://comparepv.com/stats/cell-technology) ### Cell technology share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | Unknown | 71.4% | 5 | | | PERC | 28.6% | 2 | Unknown accounts for 71.4% of the catalogue - 5 of 7 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 100.0% | 7 | ## 03. Strengths and gaps Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built. ### What this catalogue is good at - **Strength:** Strong warranty coverage averaging 25 years - **Strength:** Established manufacturer with 21+ years of experience ### Where it is thin - **Watch out:** Average efficiency of 16.6% is below the industry leading edge - **Watch out:** Limited bifacial panel options - **Watch out:** No high-power panels (500W+) available for commercial use - **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT) ## 04. In short > **Gintech:** Gintech is a solid option, offering 7 panels suitable for residential installations. With an average efficiency of 16.6% and top models reaching 18.8%, their panels deliver competitive performance. ### Common questions #### Is Gintech a good solar panel manufacturer?
