Waste and Material Reporting for Solar Panel Installation Companies
Solar panel installation SMEs play a vital role in Europe’s energy transition — but the sustainability of their own operations is increasingly under the spotlight. As part of the Corporate Sustainability Reporting Directive (CSRD) ecosystem, larger energy providers and financiers are asking their installation partners to provide data on waste, materials, and recycling.
This guide shows small and medium-sized solar firms how to report under the Voluntary Sustainability Reporting Standard for SMEs (VSME) — focusing on Basic Module B7: Resource Use, Circular Economy and Waste Management. For broader guidance, see what waste categories you must report and the CSRD guide for renewable energy SMEs.
1. Why Waste and Material Reporting Matters for Solar SMEs
Solar projects generate significant material flows — from packaging and cables to old panels and batteries. Reporting these responsibly helps SMEs:
- Prove compliance with environmental laws and waste directives
- Demonstrate responsible sourcing and recycling to clients and investors
- Reduce costs through efficient materials management
- Build credibility in tenders with CSRD-regulated partners

2. What To Report Under the VSME Standard
According to VSME section B7, SMEs must disclose:
- Whether circular economy principles are applied (e.g. reuse, repair, recycling)
- Total annual waste generated, broken down by:
- Non-hazardous waste (e.g. packaging, metals)
- Hazardous waste (e.g. batteries, oils)
- Waste diverted to recycling or reuse
- Material flows — where significant (e.g. tonnes of solar panels or cables used)
| VSME Code | Requirement | Example for Solar Installers |
|---|---|---|
| B7 (a) | Describe circular practices | Panel reuse, supplier take-back schemes |
| B7 (b) | Disclose total waste generated | 5.4 tonnes (non-hazardous); 0.2 tonnes (hazardous) |
| B7 (c) | Report recycled/reused waste | 93% recycled, 7% landfill |
| B7 (d) | Track material inputs | 14 tonnes of panels installed; 1 tonne of cabling |

3. Step-by-Step: How To Track and Report Waste
Step 1 – Identify Waste Streams
List all waste types generated by your projects and operations:
| Category | Examples | Typical Source |
|---|---|---|
| Non-hazardous waste | Wooden pallets, cardboard, scrap cables | Packaging and installation |
| Hazardous waste | Batteries, oils, cleaning fluids | Storage, electrical work |
| Reusable materials | Panels under warranty, metal frames | Returned from sites |
🔧 Tip: The EU Waste Framework Directive (2008/98/EC) defines hazardous waste — check labels and safety data sheets (SDS) for confirmation.
Step 2 – Measure and Record Quantities
Use invoices, weighbridge slips, or collector receipts to record:
- Quantity (kg or tonnes)
- Type (hazardous / non-hazardous)
- Collector or recycler
- Final treatment (recycled / reused / disposed)
| Waste Type | Quantity (kg) | Collector | Treatment |
|---|---|---|---|
| Cardboard packaging | 450 | RecycleCo | Recycled |
| Scrap metal | 820 | MetalCycle Ltd | Recycled |
| Used batteries | 65 | ReBat GmbH | Recycled |
| Oil-soaked rags | 15 | EnviroSafe | Hazardous disposal |
Keep transfer notes or waste documentation for at least five years to demonstrate compliance.
Step 3 – Calculate Recycling and Recovery Rates
Recycling rate = (Recycled waste ÷ Total waste generated) × 100
Example: Total waste: 1,350 kg Recycled: 1,230 kg Recycling rate = 91%
Disclose this metric in your sustainability report and highlight improvements each year.
Step 4 – Apply Circular Economy Principles
Under the VSME Standard, describe how your company applies circular practices, such as:
- Reusing returned or undamaged panels
- Working with suppliers offering take-back schemes
- Using recycled packaging or racking materials
- Repairing damaged panels instead of discarding them
Example disclosure:
“SolarRise Ltd applies circular principles by returning all end-of-life panels to certified WEEE recyclers and reusing metal mounting frames when feasible.”
Step 5 – Include Material Flow Data
Solar installation companies handle large quantities of components. Reporting material flows improves transparency and shows efficient resource management.
| Material | Quantity Used (tonnes) | Source | Sustainability Note |
|---|---|---|---|
| PV panels | 12.5 | European supplier | 85% recyclable |
| Aluminium frames | 3.2 | Local manufacturer | 100% recycled aluminium |
| Cables | 0.9 | EU-sourced | Low-carbon copper |
| Packaging | 0.6 | Supplier returns | Reused 70% |
4. Example: Solar SME Waste and Materials Report (VSME B7)
Company: SolarRise Ltd Sector: Solar Installation and Maintenance Employees: 22 Reporting Year: 2024 Module: Basic (B7 – Waste and Resource Use)
| Category | Waste Generated | Recycled / Reused | Partner / Method |
|---|---|---|---|
| Non-hazardous | 5.4 t | 93% | Local recyclers |
| Hazardous | 0.2 t | 100% | Certified waste carrier |
| Total | 5.6 t | 94% overall | — |
Circular Practices:
- Panels returned under WEEE take-back scheme
- Aluminium mounting systems reused or recycled
- Packaging reused between installation sites
Material Input:
- Installed 18 tonnes of new PV modules
- 3.5 tonnes of recycled aluminium used in racking
- 98% of packaging sourced from recycled material
5. Linking Waste Reporting to CSRD
Under Article 19a of the CSRD, large companies must disclose resource use and waste impacts across their value chains. By following VSME B7, solar SMEs provide their clients with credible, CSRD-compatible data covering:
- Waste generation and recycling
- Circular use of materials
- Compliance with EU waste and WEEE directives
This strengthens supplier relationships and future-proofs your reporting practices.
6. Quick Wins for Solar Installers
| Area | Action | Benefit |
|---|---|---|
| Panel Transport | Reuse packaging pallets | Reduce waste and costs |
| Procurement | Source recycled metals and low-waste components | Lower footprint |
| On-Site Practices | Segregate waste early (metal, plastic, cardboard) | Improve recycling rate |
| End-of-Life Panels | Register with WEEE-compliant collectors | Legal compliance |
| Reporting | Use a simple spreadsheet or template aligned with B7 | Save time and ensure accuracy |
7. How to Present Your B7 Data
Include a “Waste and Materials Summary” section in your sustainability report:
“In 2024, SolarRise generated 5.6 tonnes of waste, of which 94% was recycled or reused. The company integrated 3.5 tonnes of recycled aluminium in mounting structures and partnered with certified WEEE recyclers for end-of-life panels.”
