A Running Beaver crew member was working a Texas solar site when he noticed a section of ground had eroded away. He took a picture and sent it to the site's group text with a short note: be aware, this part of the site has been eroded away. The client gave him a safety award for it.
That photo did more than earn a thank-you. Because the client heard about it from the crew, they were able to take it to the builder's warranty. If you're building a 2027 maintenance budget this fall, that's the part worth planning for: finding problems while they're small. Scheduled work is easy to price. What breaks a budget is the problem nobody saw until it got big.
What Erosion Turns Into
The National Renewable Energy Laboratory's 2018 best practices guide for solar O&M, written with Sandia National Laboratories and industry partners, describes how erosion works on a graded site. Once a small rill forms, it collects more water and grows into a large gully. Left alone, that gully can endanger rack foundations and fences, expose buried conductors, and damage access roads and inverter pads. The guide also notes that drainage is difficult to improve once the array is in.
A rill is a small fix. A gully under a rack row or across an access road is a project, and once the warranty has run out, it can land on the owner. The earlier someone reports it, the more options the owner has.
What Running Beaver Crews Look For
Erosion is one of several problems that start small. These are the ones crews watch for on every visit:
Washouts and erosion, especially near racking, pads and access roads.
Grass growing into the panels. The guide lists checking for new growth shading the array as part of vegetation management.
DC cable sagging from a failed clip or hanger, dropping toward the mower path.
Leaning fence posts and gates that no longer latch.
Growth around equipment that a mower can't reach.
Grass grown over the firebreak.
RB has a field reporting app. When a crew spots a problem, they photograph it and send the owner a report showing where it is and what it needs. Daily reports show that day's work on a satellite map of the site. You decide what to do with each one.
Budget for the Rest
Not everything gets caught early. The guide says it is impossible to accurately predict when and where failures will occur. Its answer is a budget in two parts: funds for preventive maintenance, and a reserve or line of credit for corrective work. Price vegetation by the acre for your site, then give erosion and drainage, fence, cable, firebreaks and access roads their own lines. Lawrence Berkeley National Laboratory's 2025 data update puts median O&M for the utility-owned plants in its sample at about $11 per kilowatt (AC) per year in 2024, and notes that figure is only one part of total operating expenses.
Most of those lines don't need separate vendors. Running Beaver crews repair fence, re-secure cable, keep firebreaks clear between visits, and build access roads, culverts and drainage. Smaller repairs ride along with a visit the crew is already making. Running Beaver guarantees no surprise change orders on its own work. It's an ISNetworld member, prequalified on contractor safety and compliance, and fully insured.
Before You Lock the 2027 Number
Book early, too. As covered in Running Beaver's seasonal planning post, waiting until spring to book the season's work puts your site in line behind everyone else's.
Price vegetation by the acre for this site, not from another site's number.
Ask for a scope that itemizes each task, and give each gap its own line.
Set a reserve or line of credit for corrective work.
Ask how your vendor reports problems: photos, a location and what it needs.
Sign the 2027 contract before spring.
If you're building a 2027 budget for a Texas site, ask Running Beaver for a site assessment before the number is locked.
