Editorial Policy

What Is the Editorial Mission?

The editorial mission is to make solar panel angle, direction, roof geometry, and sun-position concepts understandable without turning educational content into installer sales copy. Solar Panel Angle Calculator gives planning context, not project approval.

Solar users often search for a number: best angle, winter angle, summer angle, roof angle, ZIP-code angle, or country angle. A useful answer gives the number context. Latitude sets the baseline. Hemisphere changes the season pattern. Roof pitch can limit the usable slope. Azimuth controls direction. Shade can reduce performance even when tilt is strong.

Every article or calculator page must preserve that relationship between result, limitation, and next step.

What Source Hierarchy Does the Site Use?

Solar Panel Angle Calculator prioritizes government sources, national laboratories, standards bodies, official calculators, technical documentation, and recognized industry references before using secondary explanations. Source quality controls the strength of a claim.

The source hierarchy is:

1. Government and national laboratory sources, including NREL, NOAA, DOE, OSHA, and official energy agencies.
2. Standards and code-context sources, including electrical, building, safety, grid, and product-certification bodies.
3. Official software or calculator documentation, including PVWatts, solar-position tools, manufacturer documents, and technical manuals.
4. Recognized industry organizations, certification programs, installer guidance bodies, and solar-market references.
5. Secondary educational sources used only for plain-language comparison, not for primary technical claims.

Wikipedia, forums, social media, AI-generated pages, and generic SEO blogs are not primary sources for technical claims. Community questions can reveal user intent, but official or technical sources must anchor factual statements.

How Are Solar Claims Fact-Checked?

Solar claims are checked against the entity they describe: tilt claims use latitude and angle logic, sun-position claims use solar geometry sources, performance claims use PV modeling context, and installation claims use safety, code, or professional-review boundaries.

Fact-checking separates 5 claim types:

• Calculation claims, such as fixed tilt equals latitude.
• Geometry claims, such as solar azimuth measures direction.
• Performance claims, such as tilt and azimuth influence production modeling.
• Practical constraints, such as roof pitch and shade changing usability.
• Regulatory limits, such as local code and utility requirements varying by jurisdiction.

Each claim type requires the right source class. A calculator formula cannot prove permit compliance. A government safety page cannot produce a site-specific tilt value. A PV production model cannot certify roof structure.

How Are Articles Written and Reviewed?

Articles are written from query intent, entity coverage, source claims, and practical solar planning constraints. Review checks direct answers, definitions, calculation logic, source alignment, duplicate-intent risk, and disclaimer boundaries before publishing.

The writing workflow uses 7 checks:

1. Define the central entity and page intent.
2. Map headings to distinct user questions.
3. Collect source-backed claims for technical and safety statements.
4. Assign entity relationships, such as latitude determines fixed tilt.
5. Write direct answers before explanation.
6. Review for duplicated intent across existing pages.
7. Add calculator links only where the user journey benefits.

Reviewed content can include a specialist reviewer card when the page needs solar angle methodology review. Review does not mean the reviewer approved a user's project, roof, electrical system, permit, or utility application.

How Does the Site Handle AI-Assisted Drafting?

Solar Panel Angle Calculator can use AI-assisted drafting, but AI output is not treated as a source. Human editorial review, source checking, page-intent review, and technical limitation checks control publish readiness.

AI-assisted drafting can help organize headings, rewrite dense explanations, create visual descriptions, or convert source notes into plain-language passages. AI-assisted drafting cannot invent source claims, create fake citations, approve technical accuracy, or replace expert review.

Every published page must stand on its sources, calculator logic, and editorial review. A sentence that cannot be traced to accepted solar knowledge, calculator methodology, or a listed source class must be removed or rewritten.

How Are Corrections Handled?

Corrections are handled by identifying the affected page, claim, source, calculation, and user impact. Material corrections update the page content, update date, and internal source notes where the correction changes the meaning.

Users can report errors through the Contact page. A useful correction request includes the page URL, the sentence or calculator result, the input used, the expected result, and the source supporting the correction.

Correction priority follows impact. Safety boundary errors, wrong formulas, wrong URL targets, wrong hemisphere logic, and misleading production claims receive priority. Spelling issues, phrasing issues, and minor formatting issues follow after technical corrections.

How Are Updates Scheduled?

Solar Panel Angle Calculator updates content when calculator logic changes, source documents change, standards context changes, navigation changes, duplicate-intent risk appears, or a user correction reveals a material problem.

Update triggers include:

• NREL, NOAA, DOE, OSHA, or other authority-source updates.
• Calculator formula, input, or output changes.
• New page publication that changes internal-link ownership.
• Country, state, ZIP-code, or city pages that require duplicate-content review.
• Visual or accessibility defects that reduce page usefulness.
• Source links that move, break, or become outdated.

Update dates identify editorial maintenance. A page can have an older original publish date and a newer updated date.

How Does the Site Avoid Conflicts of Interest?

Solar Panel Angle Calculator separates educational explanation from commercial influence. Editorial pages do not promise installer outcomes, solar savings, financing results, rebate eligibility, or product performance in exchange for clicks.

Affiliate, sponsor, lead-generation, or advertising relationships must be disclosed when they exist. Editorial recommendations cannot be sold as technical conclusions. A calculator result cannot become a sales claim.

When a page links to a calculator, the link exists because the calculator answers the user's next practical question. Calculator links are not used to hide missing explanations.

What Content Does the Site Reject?

Solar Panel Angle Calculator rejects content that duplicates intent, overpromises accuracy, hides limitations, mixes jurisdictions without scope, or treats a simplified calculator result as a professional design.

Rejected content includes:

• Thin country, city, state, or ZIP pages without unique data or user value.
• Articles that claim exact production from angle alone.
• Pages that use "perfect angle" language without constraints.
• Pages that present code, safety, permit, or utility rules as universal.
• Pages that copy competitor phrasing or generic solar marketing.
• Pages that cite forums, social media, or AI pages for technical claims.
