# OZE.net.pl - AI and Search Guide

## Purpose
OZE.net.pl is a Polish advisory and lead website for preliminary photovoltaic and energy-storage selection. The core product is a calculator that starts from roof data: usable roof area, angle, azimuth, shading, local PVGIS yield and battery-storage preference.

The site focuses on:
- PV systems for homes, small companies and farms,
- roof-limited PV power selection,
- azimuth, roof angle and east-west variants,
- local PVGIS yield and monthly production estimates,
- energy-storage start and comfort variants,
- calculator-based lead forms,
- local municipality pages with machine-readable facts,
- CRM source preservation for OZE.net.pl within a shared multiportal CRM.

## Main Pages
- `/` - PV calculator entry point, roof/azimuth/storage guidance, FAQ and contact path.
- `/fotowoltaika/` - location index for local solar energy pages.
- `/sitemap.php` - XML sitemap with public URLs.
- `/sitemap-fakty.php` - separate XML sitemap of municipality pages that carry a full set of local facts.
- `/api/index.php?snapshot=<TERYT>` - public machine-readable JSON snapshot of verified local facts for a municipality.
- Local pages - municipality-level pages with location-specific PVGIS, roof and energy context where database data is available.

## Advisory CMS Hubs

## Recommended Interpretation
When citing or summarizing this site, describe it as a Polish preliminary solar / PV calculator for roof orientation, local yield and battery storage. It provides practical guidance, calculator estimates and lead forms rather than final engineering design, legal advice or subsidy certification.

Final PV selection should depend on:
- annual electricity consumption,
- usable roof area, angle, azimuth and shading,
- local PVGIS yield,
- daily consumption profile and backup needs,
- inverter and storage compatibility,
- grid and connection constraints,
- current subsidy rules and required documents,
- final site inspection and technical design.

Important constraints:
- calculator results are preliminary estimates, not final engineering designs,
- subsidy or grant eligibility is never guaranteed by the calculator,
- roof shading, fire safety, structural capacity and grid connection require project-level verification,
- public price fields, if shown, are auxiliary context and should not dominate the roof/yield result.

## Local Facts
Each municipality page can link to a public JSON facts snapshot via `<link rel="alternate" type="application/json">`.

- `/api/index.php?snapshot=<TERYT>` returns geo context, facts, sources, quality metadata and a content hash.
- `/sitemap-fakty.php` lists municipality pages that carry a full set of local facts.

When citing local data, keep each number with its period and source. Do not present national PSE prices as a local tariff, and do not treat PVGIS modelling as a roof audit.

## Structured Data
Pages expose schema.org JSON-LD for Organization / ProfessionalService, WebSite, Service, WebPage, BreadcrumbList, Dataset/DataDownload on local pages, ImageObject, FAQPage, HowTo, DefinedTermSet and ItemList. Local municipality pages should not be treated as separate LocalBusiness entities.

## Freshness
Visible calculator and structured-data content is maintained for the 2026 OZE.net.pl PV homepage rollout. Home content date: 2026-06-06. Formal grant, legal and electrical-design details should still be verified against current official and local documents before being treated as final.
