What does an audit actually deliver?

A written record of what was found: physical condition, installation quality, earthing and thermal readings, design compliance, and performance against modelled expectation, with prioritised recommendations and expected recovery.

Is the audit useful during a warranty dispute?

That is one of its most common uses. Measured resistance values, thermal findings, design deviations and performance evidence give an owner something concrete to bring to a supplier.

How much has RESOLV audited?

The published record includes Valancia Housing Society in Lahore at 2,000 kWp across more than 200 houses, alongside 4,600 kWp stated as total completed projects in the audit document.

The problem

Most installed systems are never inspected against best market practice. Design documents go missing, protection settings are never verified, earthing is assumed to be correct, and performance drifts without anyone establishing what the plant should be producing.

When this solution applies

/Any client who has an installed system and wants it inspected against market practice.
/Owners taking over a plant from another contractor, or buying an existing installation.
/Systems whose output does not match the original promise.
/Portfolios that need one inspection standard across sites.

How it works

Four steps, no handover gaps.

01Physical auditSite survey, equipment inspection, installation quality, earthing checks and thermal scanning of the array for hot spots, concluded with a written report.

02Design and engineering auditReview of the contractor's design documents against the specification, the standards and the site as built.

03System performance auditOnline performance monitoring and analysis, compared against modelled expectation, reported with recommendations.

04RecommendationsEvaluation of the existing system with prioritised improvements and the basis for any warranty discussion.

Client	End user	Sector	Location	Installed capacity
Valancia Housing Society (200+ houses)	Valancia Housing Society	Housing	Lahore	2,000 kWp

Select solar projects audited by the RESOLV team, with evaluation of existing systems and recommendations for improvements. RESOLV's audit document states 4,600 kWp of total completed projects in this record.

RESOLV methodology

How the work is run.

/Inspection to best market practice rather than to the original contractor's own standard.
/Every finding documented so an owner can act on it or take it up with a supplier.
/Thermal scanning and earthing resistance measured, not eyeballed.
/Output simulation and warranty criteria reviewed in PVSyst.

Equipment and technology

Specified against the design.

/No equipment supply. Independence is the deliverable.
/Thermal imaging, earthing resistance testing, string and inverter data capture.
/PVSyst simulation for output and warranty criteria review.

What should an industrial solar feasibility study actually tell you?

A feasibility study is not a quotation with a chart on top. It is the document that decides whether capital should move at all, and on what terms.

FAQs

Solar Audit Services: what clients ask.

Yes, and that is usually the point. Audit engagements are kept independent of any supply or installation work, so the findings are not shaped by a commercial interest in replacing equipment.
