Solar Water Heater Program in India CPA-4

Audit Analysis

The Solar Water Heater Program in India CPA-4 is a Gold Standard project with a combined additionality test and project-specific baseline, but the 2025 verification report does not confirm additionality by the VVB, which is a significant integrity gap. The project has an extensive record of material findings and corrective actions across multiple verification cycles, and the verified usage rate has dropped sharply from 82.58% to 53.83% between monitoring periods, raising over-crediting concerns. Documentation quality is further undermined by a low extraction confidence rating and numerous data inconsistencies flagged by the VVB.

Project Description

Red Flags

• ⚠The 2025 verification report does not confirm additionality by the VVB (the 2024 report did), creating a direct contradiction that undermines the project's core additionality claim.
• ⚠Verified usage rate dropped from 82.58% (2023 period) to 53.83% (2024 period), a 35% decline that suggests significant system non-use or replacement, yet no buffer pool or permanence mechanism is documented.
• ⚠Extensive material findings (30+ items) and corrective actions across multiple verification cycles indicate persistent data quality and reporting inconsistencies, including incorrect ER values, inconsistent system counts, and calculation errors (e.g., 365 vs 366 days for leap year).
• ⚠No ex-ante lifetime ERR estimate is available in the extracted record, preventing a meaningful pro-rata comparison of claimed versus expected credits over the crediting period.
