PVRX · Photovoltaic Risk Index

A clearer view of photovoltaic risk.

PVRX brings system context, evidence, methodology and next actions into one risk picture.

South Africa first · For owners, insurers, risk professionals and PV professionals

What PVRX makes visible

Risk beyond the equipment.

Hardware is one layer. Records, unknowns, controls and follow-up shape the wider picture.

System configurationEquipment, arrangement, environment and change history. DC risk pointsConnections, cabling and isolation in context. Energy equipmentInverter and battery condition, protection and change. Evidence & handoverIssuer, date, scope, provenance and assurance state. Inspection & upkeepFindings, actions, verification and current relevance. Unknowns & gapsMissing information stays visible. It is never treated as reassuring.

Explore what shapes PV risk.

Choose a component or evidence layer to see what matters, what may be unknown and how a gap could be addressed.

Illustrative system · not live monitoring
Illustrated photovoltaic ecosystem with modules, DC connectors, isolation, inverter, battery, evidence, maintenance, emergency and accountability nodes.

Selected region

DC connectors

What matters
Connection compatibility, assembly, protection and operating context.
Typical evidence
Installation records, inspection findings and thermal review.
May be unknown
Connector pairing, assembly history or the scope of later changes.
Why it affects risk
Connection failure, thermal stress or incompatible interfaces may remain hidden.
Gap-closing action
Use competent, system-specific inspection and retain the resulting scope and findings.

From evidence to action

How PVRX works

  1. 01ContextUnderstand the system
  2. 02EvidenceRecord source + assurance
  3. 03MethodSelect the applicable version
  4. 04AssessReproduce from accepted inputs
  5. 05FindKeep warnings + gaps visible
  6. 06ActPrioritise remediation
  7. 07ReassessRetain the earlier history

This is the intended product direction. The production methodology and public PVRX Index remain subject to controlled validation and release.

More than a score

See what changes when evidence improves.

This illustrative journey uses no score. Each state is labelled, and none is a safety verdict or live PVRX result.

Evidence gapIsolation information is not available

The absence stays visible. PVRX does not convert missing information into a reassuring conclusion.

Who PVRX helps

Different decisions. One risk picture.

Each audience needs different detail. Context, evidence and limitations still apply.

01Residential

See what is known, what is missing and what needs attention.

02Commercial & Industrial

Trace systems, responsibilities and lifecycle evidence across complex sites.

03Insurers & Risk Professionals

Explore consistent assessment and future governed client profiles.

04Small / Off-Grid / Mobile

Make configuration and use context part of the risk conversation.

05PV Professionals

Improve handover, evidence, maintenance and remediation traceability.

Knowledge Centre

Guidance with clear limits.

Emergency readiness

What can stay energised after shutdown?

Why current, site-specific information matters.

Owner handover

Which records tell the system story?

Issuer, date, scope, changes and open actions all matter.

Methodology

Why evidence states stay distinct

See how PVRX separates provenance from whole-system conclusions.

Trust is part of the method

Explicit versions. Reproducible by design. History retained.

Who did what, when and for which part of the system? What evidence supports it?

01Governed methodologyMethod, evidence policy and engine context remain explicit.
02Deterministic by designThe same accepted basis is intended to reproduce the same governed result.
03AI is not the scoring authorityFuture explanation cannot silently change the governed result.
04Release remains gatedNo production methodology or public Index is presented as available.

PVRX is developed by LTV Technologies & Supplies. It is a South Africa-first risk-information and decision-support platform under controlled development. It is not a regulator, certifying authority, professional inspection or insurer underwriting decision.
