Two modules with identical nameplate ratings can perform very differently in the field. Temperature coefficient determines how much output is lost on hot afternoons — a decisive factor in most African installations.
Degradation rate compounds. A module losing 0.55% per year delivers meaningfully less across twenty-five years than one at 0.35%, even if the first-year output matches.
Warranty terms deserve equal scrutiny: who honours the claim locally, how long replacement takes, and whether the manufacturer has any regional presence at all.
Certification review, supplier verification and shipping coordination are part of the sourcing support Faynus provides on every enquiry.
