Estimates, not guarantees
Calculator results are estimates based on the inputs and assumptions shown on the website. They are not guarantees of solar generation, electricity savings, payback time, equipment performance, or financial return.
Results can vary
Actual outcomes can differ because of shading, weather, latitude, balcony direction, panel angle, temperature, equipment efficiency, degradation, household usage, installation quality, outages, and other site-specific conditions. Electricity prices, rate plans, export compensation, equipment prices, and incentives can also change.
Rules and requirements change
Information about laws, utility requirements, incentives, permitting, building rules, interconnection, landlords, and HOAs is provided for general informational purposes. Requirements vary by location and can change after a page is updated.
Before purchasing or installing equipment, verify current requirements with your utility, local permitting or building authority, landlord or property owner, HOA where applicable, and relevant state or local agencies.
No professional advice
Balcony Solar Calculator does not provide professional legal, financial, engineering, electrical, tax, permitting, or installation advice. Consult an appropriately qualified professional when a decision depends on those subjects.
External products and services
References or links to third-party products and services are provided for convenience and comparison. Availability, specifications, pricing, safety certification, and suitability should be confirmed directly with the manufacturer, retailer, service provider, and relevant authorities.
