Planning estimates, not professional advice
Wattcrunch provides educational planning tools and source-linked information. Results depend on user inputs, assumptions, weather, equipment, utility tariffs, incentives, financing, and future changes. They are not a quote, guarantee, tax opinion, engineering report, legal advice, or recommendation to buy.
Confirm roof conditions, shade, equipment, production guarantees, interconnection requirements, utility rules, incentives, financing terms, and tax eligibility with qualified professionals and the applicable official source before making a decision.
Sources and changes
We link to government, laboratory, utility, manufacturer, and other primary sources where available. Source pages, tariffs, products, and programs can change. We may correct, update, remove, or reorganize content without notice and do not promise that every record is current for every address or customer class.
External services and advertising
Wattcrunch may display third-party advertising and link to external websites. Those services have their own policies and terms. Wattcrunch does not endorse every advertisement, installer, lender, product, or external claim shown through those services.
Acceptable use
Do not misuse the site, interfere with its operation, scrape it at a harmful rate, attempt unauthorized access, or use outputs to make decisions that require a licensed professional without independent verification.
