GoKawiilSolar tile adoption slowed by custom engineering and repair costs, industry voices say
Swiss manufacturer Freesuns, which reports 20-30% sales growth since 2019, is weighing US expansion even as solar roof components remain made in small, non-standardized batches. Industry figures including Freesuns CEO Deborah Learoyd and solar contractor Collardson describe how each roof requires custom engineering, multi-trade coordination, and heavier regulatory paperwork, while repairs are costlier than standard panels because shingles lack built-in monitoring electronics and risk micro-fracturing when walked on.
GoKawiil's interpretation of the reporting above, not reported fact.
The account suggests that scaling solar shingles depends less on raw technology than on standardizing installation, wiring and diagnostics across the roofing and electrical trades. Until repair and installation processes become more uniform, solar roofs are likely to remain a premium niche product rather than a mainstream alternative to conventional solar panel arrays, according to the professionals quoted.
- Freesuns reports 20-30% sales growth since 2019 and is considering US expansion.
- Solar roofs require custom engineering and multi-trade coordination, raising costs versus standard panels.
- Lack of embedded electronics in solar shingles makes diagnosing and repairing faults harder and pricier.
