Module bifacial transparent européen, éligible TVA 5,5% et certifié PPE2 V2. Le BISOL BBO 510 Wc cumule gain bifacial, robustesse 30 ans et fabrication UE sur une seule référence.

Key Performances and Certifications

THE BISOL The BBO 510 is a bifacial N-Type TOPCon module with a translucent Tedlar lens, designed and manufactured in Europe (Slovenia). Its performance/warranty ratio places it above the industry standard.

• Rated power : 510 Wp STC — 578.9 Wp in BSTC (bifacial gain +13.5% with 135 W/m² on the rear face)

• Module efficiency : 22.8% — Cell efficiency: 24.7%

• Bifaciality : 72% ± 5% (effective gain to be calculated according to the albedo of the substrate)

• Power thermal coefficient : -0.29%/°C — among the best in its N-Type category

• Certified load : 7,000 Pa snow / 2,400 Pa wind — hail resistance Ø 40 mm at 99 km/h

• Certifications : IEC 61215, IEC 61701 (salt), IEC 63342 (ammonia), MCS, RG4, Class 1 fire (UNI9177), PFAS Free, PID and LETID free

• PPE2 V2 compliance for residential installations and S21 roof (modules manufactured after June 2026)

• Eligibility for 5.5% VAT under the decree of September 8, 2025 (≤ 9 kWp, self-consumption)

• Weight : 23.5 kg — lightweight module for 510 Wp facilitates handling on the roof and reduces load stresses on the structure

• Warranty : 25 years product — linear 90% at 30 years (vs 80% industry standard)

Professional application areas

The bifacial /translucent tedlar/made in EU combination opens up distinct use cases depending on the type of construction site.

Residential :
Eligibility for the 5.5% VAT rate is the central argument — one of only two available references at POwR Connect With this feature (with the Voltec TARKA Basalte 500 Wp ), the bifacial gain is particularly beneficial on roofs with high reflectivity (zinc, light-colored tiles, white membranes). The black frame + translucent Tedlar meets the requirements of the French Heritage Buildings Authority (ABF) or condominiums with aesthetic constraints.

FAQ — BISOL BBO Premium Duplex 510 Wp

Is the BISOL BBO 510 eligible for the 5.5% VAT rate for all residential installations?
Yes, provided that the total power of the installation is less than or equal to 9 kWp and that the project falls under self-consumption (decree of September 8, 2025). The RG4 certification of the module attests to the required conformity.

What bifacial gain can be expected on a real-world construction site?
In BSTC (1000 W/m² front face + 135 W/m² back face), the BBO 510 delivers 578.9 Wp, representing a 13.5% increase compared to the front face alone. In real-world conditions, the gain depends on the substrate's albedo and the mounting height. On dark bitumen membranes, the gain will be limited; on zinc or reflective surfaces, it can exceed 10%. A yield calculation tailored to the specific configuration is recommended before validation.

Is the BISOL BBO 510 compatible with standard Mounting systems ?
Yes. The 35 mm black aluminum frame is standard market dimensions. The mounting holes (14×9 mm and 10×7 mm) are also standard. At 23.5 kg, it's a particularly lightweight module for its power output, simplifying handling on the roof and installation by two people.

Is the BBO 510 compliant with PPE2 V2?
Yes, the module complies with the PPE2_v2 standard for the Residential and S21 roof categories — required for CRE4 tenders and public contracts subject to carbon criteria. Compliance applies to modules manufactured after June 2026.

What are the regulatory obligations for charging 5.5% VAT on a construction site using the BISOL BBO 510?
The decree of September 8, 2025 (Official Journal of September 9, 2025, applicable since October 1, 2025) sets out two cumulative conditions — if one is not met, the 5.5% rate does not apply:

• Le module doit répondre aux critères environnementaux : bilan carbone < 530 kgCO₂eq/kWc, teneur en argent < 14 mg/W, plomb < 0,1%, cadmium < 0,01%. Le BISOL BBO 510 satisfait ces seuils.

• The installation must integrate an EMS (energy management system) measuring production and consumption in real time, and controlling usage to maximize self-consumption.
