How to read a home solar proposal
A clear proposal connects the equipment list to your household needs. Read the design assumptions and included work alongside the headline system size.
Compare scope and assumptions, not just the number of panels.
Check what the design is based on
Look for the electricity use, roof information and backup requirements used to develop the proposal. Ask which details are confirmed and which still depend on a site check.
Panel capacity, inverter rating and battery capacity describe different parts of the system. Make sure the proposal explains each one in context.
Read the scope
Ask what is included in mounting, cabling, protection, installation, testing and handover. The proposal should identify exclusions and any work that another contractor needs to complete.
Ask for written manufacturer warranty terms and the installer service arrangements relevant to the specific equipment being offered.
Ask about the next steps
Agree the sequence of survey, final design, equipment selection, installation and handover. Any utility-related work should be discussed for your specific connection and current requirements.
Keep the final drawings, equipment documents and handover record together for future maintenance.
