Pricing FAQ

Is the free calculator really free?

Yes. No email, no credit card, no catch. We believe everyone deserves access to accurate solar data before making a major investment decision.

What payment methods do you accept?

We accept all major credit cards and debit cards via Gumroad, a trusted third-party payment processor. Payment is processed securely — we never see or store your card details.

Can I get a refund?

As this is a digital product with instant delivery, all sales are final once the report is generated. If a system error prevents report generation, contact us at [email protected] for assistance.

How is this different from what an installer gives me?

Installers provide quotes based on their specific equipment and pricing. Our report gives you an independent, third-party analysis using government data sources — so you can evaluate installer proposals with confidence.
