Expected Specific Yield Radian Team

Radian consistently bridged the gap in variance between the actual and the expected specific yield. Understanding this variance, production trending, and analysis thereof allowed the Radian team to identify performance issues not inherently obvious in O&M availability reporting.

Asset Operations: Understanding & Managing Soiling

In House Team

Radian Team (following year)

Radian performed two washings (once in early August and once in mid-September). These washings directly attributed to bridging the gap between actual and expected yield and mitigated soiling losses.

Asset Contracts: Performance Guarantee

O&M provider requested 50% share of over-performance revenue. Radian’s close analysis of assumptions saved the owner $85,000

ORIGINAL O&M CLAIM: $120,000
FINAL AMOUNT PAID TO O&M: $35,000
SAVINGS: $85,000

Radian identified 2 issues with the requested payment assumptions:

O&M used the sum of inverter output instead of the revenue-grade meter
O&M’s calculation of system losses deviated from contractually-agreed formulae
