Thanks to the use of modern 210mm G12 cells and an advanced **bifacial** design, these modules generate significantly more energy from the same area than standard single-sided solutions. The use of double glass guarantees exceptional resistance to LID and LeTID degradation, which directly translates into stable operation for many decades. This series effectively solves the problem of limited installation space by offering record power density, making it an ideal choice for solar farm investors and large industrial facilities. What sets them apart from the competition is a precisely optimized **132-cell structure**, which allows for much better thermal management and minimization of internal resistance losses. By choosing these panels, you gain **higher efficiency in low-light conditions**, which in the Polish climate is crucial for achieving a fast return on investment. The robust **Double Glass construction** also provides excellent protection against extreme weather conditions, such as strong wind or heavy snow loads. This is a substantive choice for professionals aiming to maximize yields while drastically reducing the LCOE of the entire system. ## Notable figures - At 22.2% efficiency, this panel is on par with typical \*\*TOPCon 650-700W\*\* modules - Power density of 222.4 W/m² matches the \*\*TOPCon 650-700W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 650-700W\*\* median - At 38.0 kg (3.4 kg above \*\*TOPCon 650-700W\*\* median of 34.6 kg), requires checking roof load capacity - #5722 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the warranty on SpolarPV SPV700-TG12-132BD panels? SpolarPV offers a 12-year product warranty and a 30-year linear power warranty on the SPV700-TG12-132BD series. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its rated output power. This is one of the longer linear power warranties on the market, making it a strong choice for utility-scale solar farms with extended investment and financing horizons. ### Is N-Type TOPCon technology in the SPV700-TG12-132BD better than standard PERC panels? Yes, N-Type TOPCon cells achieve higher efficiency than PERC cells due to significantly lower carrier recombination rates. The SPV700-TG12-132BD series eliminates LID and LeTID degradation issues common in P-Type technologies, resulting in a smaller initial power drop after commissioning and consistently higher energy yields throughout the module's operational lifetime compared to conventional PERC modules. ### Is the bifacial SPV700-TG12-132BD suitable for ground-mounted systems and utility-scale solar farms? Yes, the bifacial SPV700-TG12-132BD is designed primarily for ground-mounted installations and utility-scale solar farms, where the module's rear side can capture irradiance reflected from the ground surface. On light-colored substrates such as concrete, gravel, or snow, the bifaciality factor can increase annual energy yield by 10–25% compared to monofacial modules of equivalent rated power. ### How does the SPV700-TG12-132BD perform under low-irradiance conditions typical in Poland? The SPV700-TG12-132BD excels in diffuse and low-irradiance conditions common in Poland's climate. N-Type TOPCon technology features a lower temperature power coefficient and superior low-light performance compared to PERC. In Poland, where a significant share of annual energy production comes from overcast days, this translates into better capacity factor, faster ROI, and a meaningfully lower LCOE for the overall system. ### Why does the SPV700-TG12-132BD use 132 cells instead of the typical 144? The SPV700-TG12-132BD uses 132 large-format G12 cells (210 mm wafer). Fewer, larger cells deliver 700 Wp output while maintaining favorable string voltage parameters. The 132-cell G12 layout improves thermal management across the module, reduces internal resistance losses, and achieves higher energy yields compared to 144-cell configurations based on smaller wafers. This cell count is optimized for utility-scale deployments where LCOE minimization is the primary design goal. ### Is SpolarPV a Tier 1 manufacturer and what does that mean for buyers? SpolarPV is not listed on the Bloomberg NEF Tier 1 module manufacturers list, meaning it has a smaller bankability and financial track record than market-leading brands. This does not directly indicate lower module quality, but for large-scale investments buyers should verify independent laboratory certifications (IEC, PID resistance, LID tests) and carefully review warranty enforcement terms. Counterparty risk associated with a non-Tier 1 manufacturer's 30-year power warranty should be factored into project due diligence. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SPV700-TG12-132BD-6e01437b41cd.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -40 W, lighter, +3.0 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -45 W, lighter, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.6 pp | | [SpolarPV SPV660-TG12-132BD](https://comparepv.com/panel/spolarpv-spv660-tg12-132bd) | 660 W | -30 W, -1.0 pp | | [SpolarPV SPV665-TG12-132BD](https://comparepv.com/panel/spolarpv-spv665-tg12-132bd) | 665 W | -25 W, -0.8 pp | | [SpolarPV SPV670-TG12-132BD](https://comparepv.com/panel/spolarpv-spv670-tg12-132bd) | 670 W | -20 W, -0.6 pp | | [SpolarPV SPV675-TG12-132BD](https://comparepv.com/panel/spolarpv-spv675-tg12-132bd) | 675 W | -15 W, -0.5 pp | | [SpolarPV SPV680-TG12-132BD](https://comparepv.com/panel/spolarpv-spv680-tg12-132bd) | 680 W | -10 W, -0.3 pp | | [SpolarPV SPV685-TG12-132BD](https://comparepv.com/panel/spolarpv-spv685-tg12-132bd) | 685 W | Very close match | | [SpolarPV SPV695-TG12-132BD](https://comparepv.com/panel/spolarpv-spv695-tg12-132bd) | 695 W | Very close match | | [SpolarPV SPV700-TG12-132BD](https://comparepv.com/panel/spolarpv-spv700-tg12-132bd) | 700 W | +10 W, +0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +115 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/spolarpv-spv690-tg12-132bd Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
