About Helio
Helio is a free solar calculator. You enter the electric bill — the kilowatt-hours you already buy — and receive a system size, a production outlook, and cost and savings ranges, including cash, loan, and lease framing. The purpose is clarity before a sales pitch, not a pitch before the numbers.
What Helio is
Helio sizes from the bill first. Usage drives system size; size drives cost. Results are labeled estimates — a working range for homework, not a bid.
When you want a human proposal, you can contact Helio Verified installers through this site. That happens only after a full design with real information, and only if you choose to send it.
Why Helio is different
Typical solar calculators lead with a national average and a contact form. Helio leads with your kWh. Ranges stay honest instead of fake precision. There is no lead mill and no ZIP-code blast list. Verified contact is opt-in and company-specific.
Helio is a nationwide tool. The installer who visits the roof is local, and that survey is what produces a real bid. Helio does not install systems, sign contracts, or replace a site survey, a licensed contractor, or a tax professional. Helio does not quote federal tax-credit dollar amounts.
Mission
Homeowners should be able to make a confident, informed decision from their own electric bill — in plain language, without pressure. Clarity comes before commitment.
Pledge
Honest
Estimates are labeled as estimates. Helio does not invent utility rates, production guarantees, or federal tax-credit dollar figures.
Free
The calculator is free. No account is required to size a system or see a cost range.
Secure
Information you submit is used for the requests you initiate — support, a Verified application, or a proposal to the installer you chose. When you ask Helio to contact a Helio Verified installer, we send that company your design and contact details, and that company pays Helio a per-contact fee for the introduction. We do not sell homeowner lists, and we do not share your information with companies you did not choose. Forms are protected. Details are on the Privacy Policy.
