Every Detail Solar cleans utility-scale solar farms - multi-megawatt ground-mount and tracker arrays - combining robotic and manual cleaning by row geometry and verifying the result against your string-level monitoring. This page is for O&M managers and asset owners who need soiling recovery they can put in front of finance, not a vague "we clean panels" pitch.
Who this is for
Solar farm O&M teams, IPPs, and asset managers running arrays where a few points of soiling loss is real six-figure revenue. If a 2 to 3 percent soiling loss on your portfolio translates to hundreds of thousands of dollars a year - as it does on large arrays - a documented wash program is an operating decision, not a cosmetic one.
What happens on site
| Stage | What we do |
|---|---|
| Survey | Ground assessment of soiling, row spacing, access, water sources. |
| Program design | Crew lines and robotic/manual mix matched to row geometry and acreage. |
| Wash | Deionized water, row-by-row to preserve generation. |
| Verify | String-level pre/post output, normalized, documented recovery report. |
Why operators choose us for utility-scale
- Predictable scheduling means a schedulable, budgetable multi-day program.
- Robotic + manual mix so uniform rows go fast and edges/hot spots still get done right.
- Recovery you can prove against your own monitoring, with documented before-and-after production data.
- Vegetation control available so the result holds between washes (see ground-mount).
What is included in a solar farm program

- String-level performance monitoring integration
- Before-and-after reporting formatted for your O&M records, PPA compliance reporting, or investor review
Integrated vegetation mowing for solar arrays
Uncontrolled vegetation beneath and around panels causes shading losses, raises fire risk, and gives rodents habitat near wiring. Most solar farm leases and interconnection agreements require vegetation control. We maintain the clearance heights specified by equipment manufacturers, prevent erosion, and coordinate mowing with washing visits so one mobilization covers both. See vegetation management services.
Safety and site compliance
Utility-scale sites need contractors who follow electrical safety protocols and site-specific rules. Every Detail Solar carries general liability and workers compensation coverage, follows lockout-tagout procedures when working near electrical infrastructure, and arrives with the PPE and equipment the site requires. We coordinate with site managers so cleaning activity fits your operating schedule.
Utility-scale solar in California
California carries the densest concentration of utility-scale solar in the country, and most of it sits in the state's highest-soiling environments: the southern San Joaquin Valley around Bakersfield, the Antelope Valley and Mojave fringe around Lancaster and Palmdale, and the Imperial Valley. These are CAISO-interconnected sites where soiling loss through the summer and autumn dry season is paid at the hours when production is worth the most. Kern County is the worked example: agricultural dust, oilfield road dust and Mojave wind grit on the same glass, with almost no rain to rinse any of it. Our answer page on how often Central Valley solar farms should be cleaned covers the seasonal schedule, and the California page covers the rest of the state.
When utility-scale cleaning is not worth it
If your farm sits in a high-rainfall, low-soiling region and your monitoring shows a soiling ratio near 0.99, a full-array wash may not clear its cost. We will tell you that, and recommend event-driven washing (after a dust storm or ash-fall) instead of a fixed calendar. Honest scoping is how we earn the recurring contract on the sites that need it.
