Common Questions from Solar Installers
Can I price by the watt?
Yes. Use per-watt pricing for the overall system cost, or break it down into individual components — panels, inverters, racking, and labor — for a detailed proposal.
How do I handle permit costs?
Add permit applications, engineering plan sets, inspections, and utility interconnection as separate line items in a 'Permits & Fees' service section.
Can I include financing options?
You can describe financing options in your estimate's scope of work section using the rich text editor. Include monthly payment estimates to help clients decide.
