A plain-English guide to usage, roof conditions, quotes, and payback. Here’s a straightforward place to start, with the questions and details worth checking before you make a decision.
Start with your electricity use
Gather twelve months of bills and identify annual electricity consumption in kilowatt-hours. Look for seasonal patterns and consider whether future changes—such as an electric vehicle—could shift demand.
Check the home itself
Roof age, direction, usable area, shade, structural condition, and local rules all influence system design. If your roof needs replacement soon, coordinate that work before installation.
Compare purchase, loan, and lease options
Ownership structure affects upfront cost, long-term savings, maintenance responsibility, and what happens when the home is sold. A low monthly payment is not enough information to judge a proposal.
Model the complete economics
Review system size, estimated annual production, total installed cost, financing charges, rate assumptions, utility billing rules, equipment warranties, and maintenance estimates. Incentives and net-metering policies can change, so verify current eligibility with authoritative local and federal sources.
Get independent quotes
Ask multiple qualified installers to explain assumptions and use comparable estimates. Avoid guaranteed savings claims or high-pressure deadlines.
Ask every installer for a year-by-year cash-flow estimate—not only an estimated monthly payment.
