PV/ESS Pre-inspection
Check it first, before you sign. A one-time precision diagnostic performed at acquisition, M&A, sale or refinancing — from documents and visual checks to performance analysis, electrical/thermal/structural precision inspection and technical due diligence (TDD), across Basic, Standard and Premium tiers.

Find it after handover and the cost is yours.
Basic·Standard·Premium
A three-tier diagnostic system, from a quick pre-review to technical due diligence (TDD) level.
For acquisition, sale & due diligence
Up to technical due diligence (TDD) level precision diagnostics for M&A, PF and refinancing.
Pre-acquisition diagnostics
A one-time precision diagnosis at acquisition, sale or due diligence, with an evidence-based report that surfaces risk before you sign.

Onboarding process
- Step 01
Inquiry & consultation
Share plant info and agree on the inspection purpose, tier (B/S/P) and schedule.
1-2 days - Step 02
Review & site visit
Review documents and operating status, then visit the site in advance to fix the inspection scope.
1 week - Step 03
Contract & inspection
Perform the tiered inspection, metering, thermal imaging and precision diagnostics (EL/IV/drone).
2-5 days - Step 04
Diagnostic report
Deliver a diagnostic report — Standard with recommendations, Premium with risk quantification.
3-5 days
An operator inspects it directly.
An operator's eye
A company that monitors and runs O&M inspects it, flagging defects that would surface during operation.
Independent, objective inspection
Third-party diagnostics unaffiliated with the seller or contractor, for objective evidence.
Evidence-based report
Measurements and images you can take straight into negotiations and due diligence — Standard recommendations / Premium risk quantification.
Extends to TDD level
Top-level precision diagnostics for M&A, PF and refinancing due diligence.
