Four guides, one goal: buy on facts
Every guide starts from a real RFQ question — which technology, which certificate, how much gain, how many containers — and answers it with datasheet-level numbers you can verify.
TOPCon vs HJT: which to buy in 2026?
TOPCon modules reach 24.8% efficiency and carry the market's volume; HJT answers with a −0.24%/°C temperature coefficient and 85–90% bifaciality. The comparison covers efficiency, heat, degradation and price, and closes with a seven-row decision table for hot-climate and LCOE-driven projects.

IEC 61215 / 61730 / UL 61730 explained
What each certificate actually proves — performance, safety and bankability — and which ones your destination market demands. Includes the full stack from IEC 61215 to UL 61730, plus a verification checklist so you can confirm a supplier's certificates on TÜV or UL directories before signing.

Bifacial & dual-glass yield guide
Rear-side generation is worth +5–30% depending on the ground below: grass adds 5–8%, white gravel 10–20%, snow up to 30%. This guide maps albedo from 0.1 to 0.8 to expected gain and works the 0.74-year payback math for elevated and tracker mounts.

Container loading & shipping guide
A 40'HC takes about 900–936 pieces of 182 half-cell modules or 620–680 pieces of 210-format. Includes pallet counts, ISPM-15 packaging standards, vertical-stow loading safety and the Incoterms that decide who carries the freight risk.
