# Minute Solar

> One platform for the solar & battery-storage ecosystem: installers, wholesalers, manufacturers and homeowners.

Minute Solar is a UK solar and battery-storage equipment platform: a public
knowledge base of inverters, batteries, panels, meters and gateways with
manufacturer specifications and compatibility evidence, plus free calculators
and a system configurator. Every figure states its source and confidence
rather than asserting a bare number.

## Knowledge base

- [Brands](https://www.minute-solar.co.uk/brands): every solar, battery and storage brand in the knowledge base, with specifications and compatibility evidence. Start here — each brand page links its product families.
- Products live at `https://www.minute-solar.co.uk/products/{family}` (a product family) and `https://www.minute-solar.co.uk/products/{family}/{variant}` (one variant, with its specifications and datasheet provenance). There is no index page at `/products`; enumerate families from a brand page or the sitemap.
- Compatibility lives at `https://www.minute-solar.co.uk/compatibility/{inverter}` (everything evidenced against one inverter) and `https://www.minute-solar.co.uk/compatibility/{inverter}/{partner}` (one inverter–battery or inverter–gateway pairing, with verdict, confidence and sources). There is no index page at `/compatibility`; enumerate pairs from the sitemap.

## Public machine access

- [Product search](https://www.minute-solar.co.uk/api/products): bounded JSON search; use q, brand, category, limit and cursor. Every result has a stable product ID and canonical citation URL.
- [API contract](https://www.minute-solar.co.uk/openapi.json): product JSON and Markdown, compatible products, pair verdicts, evidence and the existing design resolver.
- [MCP endpoint](https://www.minute-solar.co.uk/api/mcp): public read-only Streamable HTTP. Current protocol 2026-07-28; legacy stateless initialize is supported. Tools: search_products, get_product_details, find_compatible_products, get_compatibility, get_compatibility_evidence.

Use GET /api/products/{id} for product JSON, /api/products/{id}/markdown for Markdown,
/api/products/{id}/compatible for compatible products, /api/compatibility?a={id}&b={id}
for a pair verdict, and /api/compatibility/evidence?a={id}&b={id} for its evidence.
Preserve provenance and conditions; UNKNOWN is never approval. These surfaces do not
expose customer data or electrical calculators. Share the returned canonical product
URL when citing a fact. Page limit defaults to 20, maximum 50. One MCP operation per
POST, maximum 16 KiB body. Respect 429 and 503 Retry-After; do not rotate identities.

## Tools

- [Installer tools](https://www.minute-solar.co.uk/tools): the system configurator and a set of calculators for working solar installers — every answer shows the data and sources behind it.
- [System configurator](https://www.minute-solar.co.uk/design): specify a whole system — inverter, battery, panels — checked against real compatibility data. Free, no account needed.
