Each parcel gets a SunnyScore — a proprietary ML-based solar suitability rating. Parcels are filtered against protected areas and constraint layers first, then ranked by score so the most promising land surfaces to the top.
A qualifying parcel has at least 5 contiguous flat acres (slope under 5%) and no overlap with protected areas or mapped wetlands. 28 of 28 parcels in Sussex County, Delaware currently meet that bar.
The United States (browse by state and county) and Italy (browse by region and comune). Coverage in additional EU markets is on our roadmap.
Signup is free — no credit card required. Free accounts see every signal needed to judge whether a parcel is worth a closer look (SunnyScore, flat acreage, distance ranges, constraint flags). Exact coordinates and the direct source-listing link are gated behind a subscription.
Each parcel's score blends the signals that distinguish built solar projects from unbuilt land: slope, annual sun exposure, distance to grid infrastructure, and proximity to roads and existing development. Higher scores mean a parcel looks more promising on the inputs developers price their projects on.
Yes. A one-time $49 purchase unlocks permanent access to a single listing — the full details and the direct source-listing link — with no subscription commitment. Useful if you only want to investigate one specific parcel.
No. We don't have ownership records, and we never serve agent or broker contact details — that's a deliberate legal boundary. Paid users get the direct link to the source listing and contact the agent there.
