Useful information.
Your decision.

Sources before scores.

We collect retailer offers and a small set of manufacturer reference models. Published prices, observation dates, package types, and source links stay visible. This preview does not assign product scores or claim hands-on testing.

Compare the actual equipment.

Capacity, voltage, model generation, and included components matter. Source-reviewed matches group retailer offers on one equipment page with price ranges, stock, quantities and observation dates. Unconfirmed matches, different generations, kits and used equipment remain separate.

Store coverage is visible.

Read store policies and manufacturer support profiles.

See reviewed stores, listing counts and remaining gaps. Package variants are separate offers; counts are not unique hardware models.

Local tools, visible assumptions.

The load planner and runtime calculator show the assumptions behind their estimates. Named projects stay on your browser and can be exported as JSON, spreadsheet CSV or printable briefs. No account or project analytics is required.

Information has a date.

Initial catalog observations are from November 4, 2026, with targeted additions on November 5–7. Each retailer offer keeps its own observation date. Prices and stock can change. A listed price is not a delivered or installed quote, and a battery capacity claim is not a runtime guarantee. Follow the linked original source for current terms and specifications.

Found something that needs correcting? Keep the product URL and the relevant manufacturer or retailer document so the listing can be checked against its source.

Affiliate disclosure.

SolarCompare is being developed as an affiliate comparison site. No affiliate tracking IDs are configured in this design preview. Retailer buttons currently use direct source links. Future qualifying affiliate links may earn a commission; that relationship will be disclosed and will not determine specification values or comparison order.
