installer questions
Questions to Ask Solar Installers
Ask sharper questions about design, price, warranty and support before signing.
Decision check
Ask about design assumptions, equipment, warranties, installation team, electrical extras, monitoring, post-install support and how the quote handles rebate or tariff assumptions.
Questions about your roof
Ask how shade, orientation, roof age, pitch, access and salt exposure affect the design and mounting choice.
Questions about the business
Ask who performs the installation, who signs off the electrical work and who supports warranty issues later.
Questions about the numbers
Ask what tariff, feed-in rate, usage profile and annual production assumptions were used to estimate savings.
Apples-to-apples comparison
Compare the quote, not just the price
Two solar quotes can look similar but use different panels, inverter capacity, roof assumptions, warranties and exclusions. These are the details worth checking before you commit.
System design
System size, roof layout, shade, inverter choice, export limits, and production estimate.
Equipment quality
Panel model, inverter model, battery option, product warranties, and installation warranty.
True price
Gross price, STC discount assumptions, finance cost, extras, switchboard allowances, and monitoring.
Installer fit
Local service area, accreditation, reviews, support process, and experience with similar roofs.
