BanBury and BanBury Meadows sit where Eagle's subdivisions run out into open farm ground off Beacon Light and Floating Feather. Field dust, canal irrigation, and mature trees over golf-course lots are what actually pull output off an array here — not anything wrong with the panels themselves.
The north and west edges of BanBury back onto working farm ground, and the dust that comes off a disked field in July does not stay in the field. It drifts in on the afternoon wind and settles as a fine tan film that clings harder than ordinary road dust because there is clay in it. Add the construction traffic still running Beacon Light and Floating Feather as Eagle builds north, and you have a second dust source most of the year. On a low-tilt array — anything under about ten degrees — that film never fully rinses in rain. It just migrates into a dark band along the bottom edge of each panel. That bottom-edge band is where we see the most measurable loss on BanBury roofs, and it is the first thing we check.
BanBury Meadows has real tree cover: mature ash, maple, and cottonwood planted with the subdivision, plus whatever went in along the fairways. Late April through June that canopy drops pollen and cottonwood fluff onto everything below it, and pollen behaves differently than dust. It is sticky, it takes dwell time and agitation to release, and a garden hose mostly just smears it. If your array sits under or downwind of a big tree, expect a spring soiling spike. Here is the honest part: if that same tree has grown tall enough to actually shade panels for part of the day, cleaning does nothing for that. Shade is a pruning problem or a layout problem, and no amount of washing changes it. We will tell you which one you have while we are up there.
Every yard in BanBury runs on pressurized irrigation off the canal — untreated, silty, and mineral-heavy. Fine for grass, hard on glass. If any part of your array is low-mounted on a garage roof, a shop, a patio cover, or a ground rack, and a rotor or impact head reaches it, that overspray dries into mineral scale that is genuinely bonded, not just sitting on the surface. There is an easy way to tell the two apart: dust wipes off with a fingertip, scale you can feel with a fingernail. Soap makes it worse, because the film it leaves behind gives the next irrigation cycle something to bond to. We clean with 100% pure deionized water and no soap, so nothing is left behind. Heavy scale sometimes takes two visits plus a sprinkler head turned a few degrees — we will point out which head is doing it.
Most of BanBury and BanBury Meadows went up as custom and semi-custom homes on third-to-full-acre lots, which for this build era means steep pitches, cut-up hip and gable rooflines, and a lot of architectural shingle. Arrays generally got mounted on whatever south or southwest plane was big enough, which is often the steepest face on the house. That pitch works in your favor — it sheds snow and sheets rain better than a shallow array, so you carry less standing soiling than a flat commercial install. It also means we do not walk it casually. We work these from the ground with pole-fed pure water wherever the reach allows, and off proper anchors where it does not. If an array sits on a plane we cannot get to safely, we say so up front instead of taking the job and improvising.
Cleaning restores the output you lost to soiling. That is the entire claim, and we would rather be straight about it than oversell. It does nothing for panel degradation — panels lose a fraction of a percent of rated output every year no matter how clean the glass is — and nothing for a failed optimizer, a tripped inverter, or a string that has been dark since the last windstorm. If your production is down a third and the glass looks reasonable, the problem is electrical, and you want your installer, not a cleaning crew. We quote per array once we see size, tilt, and access, and we will tell you if we do not think a cleaning is worth your money yet. Fully insured, locally owned, based in Meridian.

Once a year covers most BanBury roofs — usually late summer, after the farm dust season and before fall leaf drop. Twice a year makes sense if you are under heavy canopy in BanBury Meadows or if irrigation overspray reaches the panels. If your array is steep, unshaded, and out of sprinkler range, once every year or two is honestly plenty.
Possibly. Pollen soiling shows up as a gradual, even decline across the whole array through May and June, and it partially recovers on its own by late summer. A sudden drop, or a drop where one string reads fine and another reads near zero, is not soiling — that is an electrical or shading issue. Look at the glass first: if it looks clean and production is way off, call your installer before you call us.
Neither. We use 100% pure deionized water with soft brushes and low pressure. Soap leaves a film that attracts dust and gives canal-water minerals something to bond to, so it makes the next month worse. Pressure risks driving water past the frame seals and voiding your panel warranty. Pure water dries with nothing left behind, which is the whole point.
Usually, yes. Fresh irrigation spotting comes off in one visit. Scale that has baked on through several summers of untreated canal water sometimes needs a second pass, and we will tell you honestly if that is what you are looking at rather than promising one visit fixes it. Either way, the real fix is adjusting the head that is throwing water up there — we will show you which one it is.
We never walk on panels — that is how microcracks happen, and they do not show up until your production tells on them later. On BanBury's steeper pitches we reach most arrays with a pole-fed pure water system from the ground or from a ladder set at the eave. If an array can only be reached by walking a plane we consider unsafe, we will decline it and tell you why.
Panels are quoted per array, based on panel count, tilt, and how we have to reach them. Bundling with a window cleaning visit on the same trip is the cheapest way to do it, since we are already on site with the pure water system. Monthly and Quarterly memberships are available with no contract, and every visit carries our 7-Day Rain Guarantee.
