Compare Solaria panels on ComparePV." source: "https://comparepv.com/reviews/solaria" --- # Solaria panels, *read off the datasheets* Solaria is a leading European company focused on developing and generating solar photovoltaic energy. The company aims to contribute to decarbonization by creating a global energy model based on clean energy. Solaria specializes in the implementation and development of solar photovoltaic technology,... Everything below is computed from those 27 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Solaria does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2002 - **Headquarters:** Madrid, Spain - **Annual capacity:** 1.658 GW - **Employees:** 235 - **Listed:** BME (Madrid Stock Exchange): SLR 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 | 27 | models in the database | | Average efficiency | 20.0 % | across the catalogue | | Best efficiency | 21.9 % | their strongest module | | Power range | 310-680 Wp | smallest to largest | | Bifacial share | 19 % | 5 dual-sided models | | Average warranty | 26 years | guaranteed output term | ## 01. The top of the range The leaders of Solaria'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 | [SPV680-TG12-132BD](https://comparepv.com/panel/solaria-spv680-tg12-132bd) | 680 Wp | 21.9% | | 2 | [SPV675-TG12-132BD](https://comparepv.com/panel/solaria-spv675-tg12-132bd) | 675 Wp | 21.8% | | 3 | [SPV670-TG12-132BD](https://comparepv.com/panel/solaria-spv670-tg12-132bd) | 670 Wp | 21.6% | | 4 | [SPV665-TG12-132BD](https://comparepv.com/panel/solaria-spv665-tg12-132bd) | 665 Wp | 21.4% | | 5 | [SPV660-TG12-132BD](https://comparepv.com/panel/solaria-spv660-tg12-132bd) | 660 Wp | 21.3% | - SPV680-TG12-132BD - Monocrystalline bifacial - SPV675-TG12-132BD - Monocrystalline bifacial - SPV670-TG12-132BD - Monocrystalline bifacial - SPV665-TG12-132BD - Monocrystalline bifacial - SPV660-TG12-132BD - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/solaria?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [SPV680-TG12-132BD](https://comparepv.com/panel/solaria-spv680-tg12-132bd) | 21.9% | 680 Wp | | 2 | [SPV675-TG12-132BD](https://comparepv.com/panel/solaria-spv675-tg12-132bd) | 21.8% | 675 Wp | | 3 | [SPV670-TG12-132BD](https://comparepv.com/panel/solaria-spv670-tg12-132bd) | 21.6% | 670 Wp | | 4 | [SPV665-TG12-132BD](https://comparepv.com/panel/solaria-spv665-tg12-132bd) | 21.4% | 665 Wp | | 5 | [SPV660-TG12-132BD](https://comparepv.com/panel/solaria-spv660-tg12-132bd) | 21.3% | 660 Wp | - SPV680-TG12-132BD - Monocrystalline bifacial - SPV675-TG12-132BD - Monocrystalline bifacial - SPV670-TG12-132BD - Monocrystalline bifacial - SPV665-TG12-132BD - Monocrystalline bifacial - SPV660-TG12-132BD - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/solaria?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 27 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 | 66.7% | 18 | | | TOPCon | 18.5% | 5 | | | PERC | 14.8% | 4 | Unknown accounts for 66.7% of the catalogue - 18 of 27 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 48.1% | 13 | | | 20-21% | 33.3% | 9 | | | 21-22% | 18.5% | 5 | ## 04. 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 26 years - **Strength:** High-power panels available (up to 680W) for commercial applications - **Strength:** Established manufacturer with 24+ years of experience - **Strength:** Large-scale production capacity of 1.658 GW ### Where it is thin - **Watch out:** Average efficiency of 20.0% is below the industry leading edge - **Watch out:** Limited bifacial panel options - **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT) ## 05. In short > **Solaria:** Solaria is a solid option, offering 27 panels suitable for both residential and commercial buyers. With an average efficiency of 20.0% and top models reaching 21.9%, their panels deliver competitive performance. ### Common questions #### Is Solaria a good solar panel manufacturer?
