IBC cells in the Maxeon family use back contacts. Other ranges may use different architectures. Request the offered model’s module efficiency, dimensions, power and temperature coefficient. Cell efficiency and a power warranty are neither annual generation nor evidence of measured service life.
The references below identify product ranges. Confirm the model, availability and configuration permitted at your address in the quotation.

Confirm the model’s Swiss availability, delivery time and replacement options. The quotation must name seller, manufacturer and warranty provider, including registration requirements and covered costs. For a protected building, colour or brand does not replace authority approval. A local simulation compares useful output and total cost.
Our Verdict
Request a comparable quotation for another range on the same roof. Higher power density can be valuable when space is limited. Calculate the additional kWh actually used or sold and check who fulfils the warranty; a brand name does not establish a financial return.
Comparisons involving SunPower
Request the model code, manufacturer label and warranty document for the country and date. Commercial names alone do not identify the party handling a claim.
It applies to the models and territories named in the contract under its conditions. Check product coverage, residual power, service, registration and exclusions. The contractual duration does not guarantee fault-free operation or cover every service cost.
Compare two models and installed prices. Calculate annual benefit with the same shading, consumption and tariffs, then include differences in warranty, maintenance and replacement cost.
Obtain the model, quantity, delivery date and substitution terms in writing. Confirm whether the advertised warranty and support cover equipment supplied in your country.
Compare the models and their low-irradiance behaviour. Annual performance also depends on climate, temperature, shading and design; technology alone does not establish a fixed advantage.
Keep the invoice, model, serial numbers, original warranty, registration proof and service contact. If the contact changes, ask who handles your model and purchase date.
Sources & method
Manufacturer references for the technologies and products described. Use the datasheet, manual and contract applicable to the model supplied in Switzerland. Confirm versions, availability and functions with your supplier.
