Affiliate Disclosure
HelioCalc disclosure of commercial relationships and the separation between the calculation model and any future monetization.
Last updated: 2026-11-13.
Current status
HelioCalc currently has no affiliate relationships, no sponsored placements and no advertising. No computed number on this site depends on a commercial relationship, and no partner is able to influence a rate, an incentive, a cost benchmark or a formula.
If that changes
Any future affiliate link will be labeled as such, carry rel="sponsored nofollow" where appropriate, and be placed outside the calculation results. This page will be updated before such a link appears. The calculation kernel will remain independent: a commission will never change a computed figure, a ranked list or a state default.
How the model stays separate
The rate table, the incentive table, the cost benchmarks and the calculation kernel are all build-time data. They are read from a versioned dataset, checked against published sources, and regenerated as one unit. There is no runtime code path through which a commercial partner could alter a computed figure, and no ranked list of installers on this site whose ordering could be purchased. If a commercial relationship is ever added, it will live in a clearly marked block outside the results area and will be described here first.
Why we state this
Residential solar involves a five-figure purchase, and a calculator that earns a commission on a signed contract has an incentive to make the answer look better. We would rather say plainly that no such relationship exists than leave the question open.
Frequently asked questions
Do you earn commission on solar quotes?
No. HelioCalc currently has no affiliate relationships and does not collect leads.
Are the state benchmarks influenced by installers?
No. They come from EIA, EnergySage, LBNL and NREL sources, or are labeled modeling benchmarks.
