How do you plan ground mounted solar for a farm or business?

Ground mounted solar needs suitable land, an agreed cable route and a connection design matched to your business demand. Start with at least 12 months of electricity records, as BRE recommends for commercial assessment [S1]. Check planning and agricultural constraints before treating spare land as available for generation. Checked October 2026.

Is ground mounted solar suitable for your farm or business?

Ground mounted solar PV, meaning photovoltaic generation, separates your panel layout from your roof. Start by asking what the electricity will serve: refrigeration, processing equipment, workshops, offices or chargers. Request a consumption-led design rather than filling a field and finding a buyer for the output afterwards.

BRE’s commercial guide explains why consumption data matters when comparing generation with site use. Give the designer the records for the buildings that will actually connect to the array. Flag seasonal closures, planned machinery and changes in tenancy. Treat future loads as a separate scenario until they are committed. [S1]

A workable roof may avoid occupying land, while a ground array may avoid unsuitable roofing. Ask for both options where they are practical. Compare the complete installation boundary, including cables and connection costs. Our farm diversification guide helps frame the wider site decision without assuming that electricity sales replace your existing business.

Which land can you use for ground mounted solar panels?

Draw the proposed boundary before asking for a price. Include access, drainage, buildings, trees, overhead lines, underground services and the route to the electricity connection. Historic England recommends a site survey and highlights landscape, archaeology and installation impacts for ground arrays. [S3]

Use the following as a briefing checklist, rather than evidence that the land is approved:

Ask the installer to identify where machinery can turn and where equipment can be maintained. Keep delivery routes away from operational areas in the proposed construction plan. If cables cross another title, settle access and repair rights before relying on that route in the quotation. Have your solicitor confirm the required documents.

Does a ground mounted solar array need planning permission?

Do not apply a domestic garden exemption to a commercial field. Obtain a written view from your planning authority using the proposed boundary, dimensions and associated equipment. England’s guidance identifies agricultural land quality, landscape, glint and glare, heritage and restoration among solar-farm considerations. [S2]

That guidance favours previously developed or non-agricultural land where appropriate and requires attention to land quality when greenfield sites are proposed. It also discusses agricultural use and biodiversity around arrays. It does not approve your field or make grazing a substitute for assessment. [S2]

This planning discussion is for England. For land in Scotland, Wales or Northern Ireland, obtain advice from that nation’s planning authority and use its current policies. Confirm the consenting route before commissioning a survey package intended for a different process.

Read ground mounted solar planning and agrivoltaics to distinguish a planning proposal from a combined farming and generation design. Ask the council which studies it expects for your actual site.

How much power should your ground mounted solar system produce?

Separate power from energy. Kilowatts, or kW, describe power; kilowatt-hours, or kWh, describe energy over time. Ask for the panel capacity, inverter capacity and proposed export limit as separate entries. They answer different questions and should not be presented as interchangeable.

PVGIS estimates generation from location and system assumptions, including slope, orientation and losses. Request the calculation inputs and a monthly output profile. Ask the designer to explain how local shade, cable losses and any export restriction have been included. A regional yield copied into a quotation is not a site survey. [S5]

Compare the output profile with your operational demand. If the summer surplus is large, request a smaller-array option alongside storage or export options. Price each separately. Read commercial solar sizing before deciding whether additional panel capacity serves your business.

What grid connection and cable work should you budget for?

Your distribution network operator, or DNO, manages the local electricity network. UK Power Networks provides commercial solar and storage connection guidance, including routes for combined technologies. Your own DNO must confirm the relevant application and network requirements. [S4]

G99 is an engineering recommendation used for generation connection assessment. Ask the installer to identify the applicable route and approved operating settings. Planning approval and the network’s connection agreement belong in separate parts of the project file.

Request a measured cable route, a trenching scope and reinstatement costs. Include road crossings, services, switchgear, metering, communications and any transformer works in the cost comparison. Ask what happens to the budget if the first route proves unavailable. Do not treat a connection enquiry as a fixed-price offer.

What should you do next?

Prepare a boundary plan, electricity records, title information and a list of operational constraints. Request a survey-led proposal with clearly assigned planning, connection, maintenance and removal responsibilities. Compare fully funded, part funded and self funded offers using the same technical design and ask your accountant to review any tax assumptions. Then get matched with an installer that covers your area.
