About the project
Independent software for a decision usually shaped by sales incentives
SolarLinkup helps US homeowners inspect system sizing, production, price, financing, and policy assumptions before signing a residential solar agreement.
Who maintains it
SolarLinkup is maintained as an independent software engineering project. Its calculations are implemented as tested code, and its external data connections are documented on the methodology page.
The project does not claim to be a licensed installer, structural engineer, electrician, tax adviser, financial adviser, utility, or government agency. Final decisions still require the appropriate local professionals and official utility documents.
No lead sales
No phone number is required, and calculator use is not sold to installers as a sales lead.
No transaction commission
The model does not earn more when a user chooses a larger system, loan, installer, or battery.
Named evidence
Live providers, fallback estimates, policy citations, effective dates, and limitations are labeled.
Editorial standard
- 1. Prefer primary sources. APIs, statutes, regulators, tax agencies, and utility tariffs come before summaries.
- 2. Separate fact from assumption. Configured planning values are labeled rather than presented as measured data.
- 3. Show model limits. The product states where engineering, tax, tariff, and site-specific review is still required.
- 4. Correct material errors. Policy and formula changes are updated in the product and covered by focused tests where practical.
