Case Study: Cleantech Solar boosts PV performance validation with Solargis satellite data

Solargis validates ground-based measurements for Cleantech Solar

Cleantech Solar, a leading solar developer and operator in Asia, faced challenges with the accuracy of ground-based irradiance measurements at its many sites in dusty and polluted industrial zones. The accumulation of dirt on sensors made it impossible to maintain data accuracy through daily cleaning. To address this, Cleantech Solar engaged vendor Solargis to provide validated satellite-based solar resource data to verify asset performance.

Solargis provided its highly accurate satellite data to validate ground measurements, which helped Cleantech Solar isolate underperformance and improve the certainty of production estimates. This data, delivered via API, supported strategic decision-making and increased investor confidence. The partnership with Solargis enhanced operational transparency and is estimated to significantly increase annual revenue by improving asset performance.
