Our goal is to make solar planning concepts easier to understand and to show the assumptions behind our tools.
Sources and estimates
Technical explanations should identify their sources, units, assumptions, and limitations. Worked examples are illustrations, not promises of output, savings, safety, or regulatory compliance. Equipment specifications and local requirements should be checked with the original provider or authority.
Corrections and updates
Readers can report errors through our contact page. A displayed update date should reflect an actual content review or material change. We do not claim that every article has been independently reviewed by an engineer.
Commercial transparency
Advertisements and affiliate relationships, when present, should be clearly distinguished from editorial content. Links should not be described as independent recommendations if a commercial relationship affects their placement.
How to read our calculations
We distinguish manufacturer specifications, our calculated examples and measurements supplied by readers. An example is not a hands-on product test. Inputs such as conversion efficiency, battery reserve, seasonal sunlight and appliance use are shown so readers can replace them with their own values. A calculator result is a planning estimate rather than a product certification or installation design.
Sources generally link to manufacturer documentation, public agencies, research organizations or university extension material. Equipment versions, utility processes and warranty terms can differ. The exact manual, contract and local authority remain the appropriate sources for a specific installation.
Images and illustrations
Some editorial images on this website are AI-generated illustrations. They are used to explain a topic or establish visual context, not as evidence that we installed, inspected or tested the pictured system. Equipment appearance in an illustration should not be used to identify a model, wiring method or approved installation configuration.
Tables and numerical examples should identify assumptions and units. Illustrative scenes do not establish measured output, product performance, a customer experience or an endorsement by a manufacturer.
Reporting a correction
Send the page URL, the sentence or calculator input in question, and a supporting source through our contact page. For a calculator discrepancy, include the values entered, the displayed result and the result you expected. Do not send account passwords, utility login details or private contract identifiers. This makes the issue reproducible without exposing your personal information.
