The template includes the federal 30% tax credit (up to $1,000). You can add state-specific rebates or utility incentives for your area.
Can I adjust labor rates for my market?
Yes. All labor rates, complexity multipliers, and per-foot wiring costs are fully customizable to match your local pricing.
How do I handle panel upgrade assessments?
The calculator provides estimates for common scenarios. You can add a note that final panel requirements are determined during the site assessment.
Can I collect customer information for follow-up?
Yes. The submit button captures contact details so you can schedule site assessments with qualified leads. Connect to your CRM via webhooks.
