SOLAFIL

Last verified 2026-10-06.

• Legal manufacturer as printed: 積水ソーラーフィルム株式会社 (English gloss: Sekisui Solar Film).
• The maker describes SOLAFIL as its brand for film-type perovskite solar cells, which it presents as thin, light and bendable.
• A joint release dated 27 March 2026 says commercialisation has started, with products for installation on metal roofs.
• Supply in the 2026 financial year is limited to output from existing equipment, going to named Japanese public projects under a Ministry of the Environment programme and a Tokyo Metropolitan Government programme; the maker says expanding supply through a 100 MW scale line planned for the 2027 financial year is its top priority.
• The reviewed maker pages establish brand-level form and programme supply, but do not establish an exact model code, rated electrical specifications, governing warranty terms or an applicable certification listing. These four documentary gates remain open, so SOLAFIL cannot be scored as an exact product yet.
• SOLAFIL is a brand for a product line rather than a single rated product, and this record is not joined to any scored or evidence record.
• The current Sekisui Solar Film product page describes film thickness of 1 mm, together with lightness and flexibility. This is a maker brand-level description, without an exact model or revision join, length, width, mass or defined measurement method. It does not establish a rated power, efficiency, temperature coefficient or electrical operating limit for a specific commercial module.
• A Sekisui release dated 25 September 2026 states that supply has started to the Ministry of the Environment support programme and Tokyo early-adoption programme. This updates the March business-start announcement and its named Japanese metal-roof scope. It remains an attributed maker programme-status statement, not independently verified shipment volume, unrestricted retail availability or evidence that every illustrated application is commercially approved.
• The current Sekisui Europe article says the initial commercialisation focus is Japan and explicitly states that SOLAFIL is not yet available in Europe. Overseas introduction depends on further industrial and market development. Publication on a European company website is not evidence of European availability, and these sources do not establish Australian availability or approval.
• No governing exact-product warranty instrument was recovered from the reviewed sources. Covered models, warrantor obligations, commencement, duration, output/degradation entitlement, exclusions, registration, transferability, claims, remedies, labour, freight and removal/reinstallation costs remain unresolved. Programme participation and the manufacturer’s scale-up plans do not create those purchaser entitlements.
• The makers describe demonstration projects and possible applications across roofs, façades and infrastructure. These descriptions do not establish an independently reviewed exact-model annual yield, degradation rate, field failure rate, environmental durability or fire rating. Participation in a public programme is not a substitute for an applicable certificate or test report. The planned FY2027 100 MW line is future production capacity, not module rated power or verified completion of that line.
