When planning new factory construction, most property owners opt for a conventional sequence: erect the roof first, then mount solar panels later (BAPV). However, for newly built steel structure factories, one-step integrated BIPV delivers far superior cost efficiency.
Integrated Building Materials: Eliminate Secondary Installation & Conventional Metal Roof Sheets
BIPV solar modules directly replace standard metal roof sheets or Al-Mg-Mn roof panels, forming an integral part of the building envelope.
Cut redundant material procurement
No separate roof panels and mounting brackets required. BIPV modules serve as the roof itself, substituting traditional metal sheets, waterproof layers and thermal insulation layers. It reduces roof dead load by 15–20% and cuts steel consumption for the steel structure by 8–12%.
Superior perforation-free waterproofing
Adopts dual-seal waterproof technology. Full-coverage flashing covers gaps between module frames, and dual-direction gutters are used at overlaps, eliminating leakage risks caused by bracket drilling in BAPV systems.
Integrated wiring layout
PV cables and weak-current lines are routed together with steel structural wiring, concealed inside steel purlins. No extra drilling is needed to avoid damaging the roof structure and shorten construction periods.
Take a 10,000 ㎡ new factory as an example: the cost savings on conventional roof materials via BIPV can directly reduce initial investment by 10%.
Full Life Cycle Cost (LCC) Comparison: BIPV vs BAPV
Conventional metal sheet roofs require major overhaul or replacement after 10–15 years, incurring secondary dismantling, reinstallation and production shutdown losses. BIPV systems share the same service life as solar modules (≥25 years), drastically amortizing full life cycle costs.
Conclusion: If solar power is planned for your new factory, pre-integrated BIPV outperforms the “roof-first, solar-later” BAPV solution in material costs, labor expenses and maintenance expenditures. Incorporating BIPV into the early design phase delivers optimal performance and minimal overall costs.
