Contact Us
We are a small, independent publisher and we read every message. Questions, corrections and better data sources are all genuinely welcome.
The best and only way to reach us is by email:
We monitor this inbox at least once every business day and aim to reply within a couple of business days. There is no contact form, because we do not want to collect more of your information than we need — a direct email keeps it simple and keeps you in control of what you share.
What to write to us about
- Corrections and accuracy reports. If a constant looks out of date or a state figure seems wrong, tell us — ideally with a link to the current official source. Accuracy is the whole point of the site, so these messages go to the top of the pile.
- Data-source suggestions. If you know a better, more authoritative source for an install price, tariff, feed-in rate or rebate, we want to hear about it.
- How the calculator works. If a result surprised you, the Methodology page shows the full formula and every input — but if something is still unclear, ask and we will explain.
- Privacy requests. For any question about data or your rights, see our Privacy Policy or email the same address.
What we cannot help with
The Solar Payback is an independent calculator, not a solar installer, retailer or adviser. We cannot give you a binding quote, recommend a specific installer, or provide financial, tax or legal advice. For a firm price and a system designed for your roof, contact a licensed installer in your state. Our numbers are a solid, sourced starting point to take into that conversation.
Estimate only — not financial advice. See About for who runs The Solar Payback and how it stays independent.
