How to read land suitability for solar farms
A good solar site is not just a large empty parcel; slope, aspect, shadow, roads, power lines and zoning have to be read together.
When screening land for a solar project, parcel size is often the first number people notice. Size matters, but it is not enough. Panel layout, cable runs, maintenance roads, transformer access and shading have to be evaluated as one spatial problem.
Flat or gently sloped parcels with open southern exposure are usually easier to interpret. A north-facing slope, a narrow parcel shape or heavy internal elevation change can reduce the usable area even when the title-deed area looks generous.
Layers to check first
- Slope: affects racking, earthworks and maintenance access.
- Aspect: southern exposure is one of the key production-related readings.
- Shadow: hills, trees, buildings and pylons should be considered separately.
- Road access: determines installation and maintenance logistics.
- Power-line distance: a critical input for connection cost and technical feasibility.
In Parselo, parcel boundaries, terrain and nearby geo layers can be read on the same screen. Video and digital showcase outputs help explain why a parcel is being presented as a solar candidate, while comparison tools place two sites next to each other under the same criteria.
Boundary note: Parselo provides preliminary analysis and presentation support; it does not replace grid connection approval, zoning permission, licensing, expropriation review, final yield studies or engineering design.
