• Insurance & architectural services: Fee-based revenues that complement contracting work and provide integrated service offerings for developers and homeowners.

• Integrated supply chain: In-house manufacturing combined with targeted outsourcing lowers costs and secures parts supply for key components.
• Extensive branch network: Local sales offices enable rapid response for repairs and installation, driving higher customer retention and smaller delivery windows.
• Product-service bundling: Bundles (product + installation + maintenance) increase upfront revenue per project and create recurring revenue through service contracts.
• Asset utilization: Use of company-owned real estate and solar installations to generate non-product income and improve return on assets.

• Order intake and backlog levels by region and segment.
• Gross margin on manufactured products versus contract services.
• Recurring revenue ratio coming from maintenance and service contracts.
