Why does grass need cutting on a solar farm?

Shade on modules, fire risk and insurer requirements. FM Global’s general guidance is to keep vegetation to 6 in. where irrigation is not practical. Some insurers set their own limits, so check your policy.

Posts, trays, edges and the ground a machine cannot reach. Those stay with your crew or landscaper.

How does this fit with sheep grazing?

Many owners combine them. We plan the mowing zones around the flock and will not claim a robot replaces grazing.

What belongs in a solar mowing contract?

Frequency, height measured at the lowest module edge, coverage, reporting, insurance and liability. Every Detail Solar lists liability and workers’ comp as the minimum.

Who services the mower after deployment?

We do. Support is 24/7 with 10-minute specialist triage, backed by regional service engineers in every state we service, three check visits a year and a 12-month warranty.

Updated October 2026

Service Robot Co. helps solar owners and O&M teams pick the right commercial robotic mower for each site, lease it on a three-year term, deploy it, train the crew and service it. We match the machine to your panel clearance, slope and layout. Posts, trays and tight edges stay manual.

Who handles vegetation on a solar farm?

The person who signs is rarely the person who mows. The contract usually runs through an owner, an asset manager and an O&M team.

Asset owners and investors: They sign service contracts and set the KPIs. Solar Power World describes them handing coordination to an asset manager or an O&M company.
Utilities that own their solar: Some utilities run it in house. Indiana Michigan Power says it uses a robotic mower at all five of its solar farms.
O&M companies and landscapers: Mowing is hard to staff, so it tends to land with seasonal crews or outsourced landscapers, per Renu Robotics’ own write-up.
Whoever reads the contract: Energy Business Review reports buyers checking service contracts harder as portfolios grow: frequency, coverage and reporting. That piece covers service contracts in general, not mowing alone.

What can a robot mow on solar?

The robot takes

Repeat mowing between rows and along access lanes
Steady cut height so growth does not reach the modules
Scheduled passes you can report against a vegetation KPI

The crew keeps

Posts, trays and the ground right at the edges
Spots below the lowest module edge that the machine cannot clear
Fence lines, drainage and inverter pads
Spraying, grazing coordination and fire-break work

What should you check first?

Clearance is the first question. Insurance and contract wording come next.

What should you check first?
Topic	What to know
Panel clearance	One vendor guide puts the lowest point on fixed-tilt at 18 to 36 in. and some trackers at about 18 in.
Height spec in the contract	Tie it to the lowest module edge at the lowest tracker position, per Every Detail Solar
Vegetation height	FM Global’s general guidance is 6 in. where irrigation is not practical. Check your own policy.
Slope and ground	Walked during the site assessment
Who mows the edges	Crew or landscaper, agreed up front
Lease term	3 years, $1 buyout at the end

What does Service Robot Co. do?

We pick the right machine for your properties, put it on a 3-year lease with a $1 buyout at the end, deploy it, train your crew, and service it.

For solar we begin with the panel drawings and the contract height spec, then walk the site, so the machine we pick matches the clearance you actually have.

01
Pick
We walk your properties and choose the machine that fits, or tell you honestly if none does yet.
02
Lease
3-year lease with a $1 buyout at the end, quoted after the site assessment.
03
Deploy
We map the zones and no-go areas, set the dock and start the routes.
04
Train and service
Your crew is trained. When something stops, one number gets a specialist.

Where does it not fit on solar?

Clearance decides, and some sites fail it.

Low trackers and tight rows
If the machine cannot pass under the lowest module edge, it does not mow that row. AutoAcre says posts, trays and edges stay manual even with a robot.
Sites run on sheep
Grazing and mowing can sit side by side. The American Solar Grazing Association census found about two-thirds of graziers also use other methods, including mowing. We would plan around the flock, not replace it.
Overgrown or rough ground
A robot keeps a kept site kept. It does not reset years of growth. Start with a clean-up by the crew.

Common questions

It depends on clearance at the lowest module edge. Vendor guides put fixed-tilt low points at 18 to 36 in. and some trackers at about 18 in. We check your drawings and walk the site before picking a machine.
