Solar PV in ESG & Scope 2 Reporting

The reporting frameworks that solar PV affects

A commercial solar PV installation reduces your Scope 2 emissions under the GHG Protocol — the international standard underpinning every major UK and EU sustainability framework. The same kWh-displaced data feeds into SECR (Streamlined Energy and Carbon Reporting) for UK quoted companies and large unquoted entities, into TCFD-aligned climate risk disclosures, and into the EU's Corporate Sustainability Reporting Directive (CSRD) for any UK business operating in the EU.

What KMM provides at handover

Every commercial install ships with an ESG handover pack containing:

• Installed capacity — kWp DC and AC, panel make/model/serial range, inverter spec
• Modelled year-1 generation in kWh, broken down by month
• Self-consumption assumption with HH-data backing
• Scope 2 displaced emissions calculation — using BEIS conversion factors for the relevant grid mix year
• Lifecycle embodied carbon of the panels + inverters (cradle-to-grave LCA estimate)
• Estimated net carbon payback — typically 1.5-2.5 years on UK roof PV
• Estimated 25-year cumulative CO2e displacement
• REGO equivalence statement — confirming whether the system qualifies for REGO certificate generation
• Monitoring portal export schedule — auto-generated quarterly reports formatted for SECR / GRESB

SECR reporting

UK quoted companies and large unquoted entities have mandatory SECR reporting under the Companies (Directors' Report) and Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018. Solar PV affects three SECR line items:

• Annual electricity consumption (kWh) — reduced by the self-consumed solar generation
• Annual Scope 2 emissions (tCO2e) — reduced by the kWh-displaced × BEIS factor
• Intensity ratio — kWh / unit of business output (e.g. kWh per £m revenue, kWh per FTE, kWh per m² floor area) — denominator unchanged, numerator reduced

KMM provides the underlying data; your reporting accountant calculates the final SECR figures using your business-specific intensity denominator.

TCFD-aligned disclosures

The four TCFD pillars — Governance, Strategy, Risk Management, Metrics & Targets — all benefit from documented solar PV investment. Specifically:

• Strategy: demonstrates climate-aligned capital allocation; solar PV is a transition-aligned asset under the EU Taxonomy
• Metrics & Targets: measurable kWh and tCO2e contribution to net zero pathway
• Risk Management: hedges against electricity price volatility (a transition risk under TCFD's risk categories)

CSRD for UK businesses in the EU

UK businesses operating in EU member states with EU subsidiaries above the CSRD thresholds (250+ employees, €40m turnover, €20m balance sheet) face CSRD reporting from FY2025 onward. The European Sustainability Reporting Standards (ESRS) E1 Climate Change disclosures require:

• Scope 1, 2 and 3 emissions inventory with year-on-year change
• Transition plan alignment with 1.5°C scenario
• Capital allocation to climate adaptation and mitigation

Solar PV is a material disclosure under all three. KMM's commercial handover pack maps directly to ESRS E1 data points.

Customer-supplier Scope 3 reporting

If you supply to retailers, manufacturers or service businesses with their own Scope 3 reporting obligations, solar PV at your premises affects their supply-chain emissions calculation. Many large UK retailers (Tesco, Sainsbury's, M&S, John Lewis, Co-op) now require Scope 1+2 reporting from key suppliers and offer preferential commercial terms to suppliers demonstrating active decarbonisation. Documented solar PV investment is one of the strongest signals.

Worked example

Reporting cadence

Most commercial customers integrate solar data into their quarterly ESG dashboards. KMM's monitoring portals (Sungrow iSolarCloud, SolaX SolaXCloud) export quarterly auto-formatted CSVs containing generation, self-consumption, export, and tCO2e displaced — drop-in to your existing reporting workflow.
