Turn three different-looking quotes into one comparable sheet

Start here

For “Turn three different-looking quotes into one comparable sheet”, record module DC capacity and inverter AC capacity separately. Two “5 kW” quotes may not describe the same DC/AC design.

What applies to this exact problem

Check these first

• 1. Normalize system size: Record module DC capacity and inverter AC capacity separately. Two “5 kW” quotes may not describe the same DC/AC design.
• 2. Lock exact equipment models: Ask for manufacturer, model number, quantity, ratings and warranty documents. Reject vague labels such as “Tier-1 panel” without a model.
• 3. Compare structural and electrical scope: Review mounting material, roof attachment, corrosion protection, cable lengths, isolators, earthing, surge protection, monitoring and shutdown labels.

Fix it in this order

1. 1. Normalize system size: Record module DC capacity and inverter AC capacity separately. Two “5 kW” quotes may not describe the same DC/AC design.
2. 2. Lock exact equipment models: Ask for manufacturer, model number, quantity, ratings and warranty documents. Reject vague labels such as “Tier-1 panel” without a model.
3. 3. Compare structural and electrical scope: Review mounting material, roof attachment, corrosion protection, cable lengths, isolators, earthing, surge protection, monitoring and shutdown labels.
4. 4. Separate approvals from promises: List what the vendor will actually handle for DISCOM, net metering or scheme workflow and what remains your responsibility. Never treat an unapproved subsidy as guaranteed cash.
5. 5. Compare payment and warranty risk: Prefer milestone-linked payments with clear deliverables. Check who provides product warranty, workmanship warranty and local service after installation.
6. Compare structural and electrical scope Review mounting material, roof attachment, corrosion protection, cable lengths, isolators, earthing, surge protection, monitoring and shutdown labels.
7. Separate approvals from promises List what the vendor will actually handle for DISCOM, net metering or scheme workflow and what remains your responsibility.
