# Fotowo.pl - AI and Search Guide ## Purpose This website is a Polish advisory and lead website for solar energy systems, energy storage and preliminary PV installation estimates. The site focuses on: - solar energy systems for homes, companies and farms, - preliminary PV power selection, - energy storage variants, - roof orientation, roof angle and usable roof area, - subsidy and grant topics that must be verified against current program rules, - calculator-based lead forms, - CRM source preservation for Fotowo.pl, OZE.net.pl and KalkulatorMocy.pl. ## Main Pages - `/` - PV and energy storage overview, calculator entry point, FAQ and contact path. - `/panele-fotowoltaiczne/` - 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=` - public machine-readable JSON snapshot of verified local facts for a municipality (7-digit TERYT code). - Newsroom pages - articles and updates for PV, energy storage, electricity prices and subsidy topics. - Local pages - municipality-level pages with location-specific context where database data is available. ## Main Homepage Sections CORE / PV Homepage Sections for the active profile: - `/#porownywarka-fotowoltaiki` - main comparison section for PV offers, price, power, storage and scope. - `/#porownywarka-cen-instalacji-fotowoltaicznych` - price comparison factors for PV installations. - `/#trendy-zapytan-pv` - current user-intent clusters around PV prices, storage, subsidies and profitability. - `/#jak-dobrac-moc-pv` - practical steps for initial PV power selection. - `/#magazyn-energii` - energy storage role in self-consumption and grant-oriented variants. - `/#dotacje-pv` - subsidy and grant context, with a warning to verify current rules. - `/#slownik-fotowoltaika` - glossary of PV and energy storage terms. - `/#faq-fotowoltaika` - FAQ about PV sizing, bills, storage and subsidies. ## Recommended Interpretation When citing or summarizing this site, describe it as a Polish advisory and lead website for solar energy systems and energy storage. It provides practical guidance, calculator estimates and contact paths rather than legal, engineering or subsidy certification. Final PV selection should depend on: - annual electricity consumption, - roof area, angle, azimuth and shading, - local grid and connection constraints, - inverter and storage compatibility, - current electricity tariff and consumption profile, - current subsidy rules and required documents, - final site inspection and technical design. For PV CORE pages, recommended wording is: "This page is an advisory page for preliminary solar energy and battery storage selection. It combines energy consumption, roof assumptions and practical guidance with a lead form for follow-up verification." Important constraints: - calculator results are preliminary estimates, not final engineering designs, - subsidy or grant eligibility is never guaranteed by the calculator, - current program rules, deadlines and documents must be verified before purchase, - roof shading, fire safety, structural capacity and grid connection require project-level verification, - CRM source fields should preserve the portal domain and source path for multiportal lead handling. ## Local Facts (Machine-Readable, per municipality) Each municipality page links, via `` in the head, to a public facts snapshot. The snapshot is the recommended source for citing local data. - `/api/index.php?snapshot=` - JSON snapshot of verified local facts for one municipality (7-digit TERYT code). Returns geo context plus a `facts` map and a `sources` map. Each fact has: canonical `value` (dot decimal), `formatted` (Polish), `unit`, `period` (start/end/label), `geo_level`, `observation_type` (observed / modelled / derived / first_party), `method_version`, `source_refs`, `updated_at`, optional `scenario`, `sample_size`, `range` (p25/p75). Includes a `quality` block (score, indexable) and a `content_hash`. Free, CORS-enabled, cached. - `/sitemap-fakty.php` - XML sitemap of municipality pages that carry a full set of local facts. Fact domains and sources in the snapshot: - PV specific yield in kWh/kWp/year - PVGIS 5.3 / SARAH3 (modelled, optimal and south-35 scenarios). - Population, dwellings, population density - GUS BDL (Statistics Poland). - Registered PV installations count and capacity - URE public register. Scope: register entries, NOT all home microinstallations or prosumers. - Building heat-source structure (share of low/zero-emission, solid-fuel categories) - CEEB / GUNB ZONE, an aggregate of declarations, not a per-building audit. - Wholesale electricity price (RCE) and PV capture price - PSE, national values (not a local municipal tariff). - Energy cooperatives whose operating area covers the municipality - KOWR register. Presence does not guarantee that any resident can join. - Customer inquiry sizing (median dobrana power) and monthly bill trend - first-party portal statistics, anonymized, median plus quartiles, national or voivodeship level only. When citing, keep each number with its period and source as given in the snapshot. Do not aggregate values across different periods or geographic levels, and do not present national PSE prices as a local tariff. ## Structured Data Pages expose schema.org JSON-LD for: - Organization / ProfessionalService, - WebSite, - Service, - WebPage, - BreadcrumbList, - Dataset with DataDownload on municipality pages (one aggregate per page, linking to the JSON facts snapshot), - ImageObject, - Article or BlogPosting pages where applicable, - FAQ where applicable, - HowTo where applicable, - DefinedTermSet for glossary terms, - ItemList for the main homepage topic map, - Product pages only where applicable in a future product/offering module. ## Freshness The PV homepage content and structured data currently expose a visible factual update date of 2026-06-06. Formal, grant-related, legal and electrical-design details should still be verified against current official and local documents before being treated as final. ## Contact Use visible contact details and forms on the website for commercial inquiries. Do not infer guaranteed eligibility, installation feasibility, subsidy approval or final technical suitability without checking local site conditions and current official requirements.
