Solar panel cleaning in Blaine, MN
Pure water, a soft solar brush and a cool panel, the way panel makers ask for it.
Blaine water runs about 310 to 360 PPM of hardness, and those minerals can permanently etch a solar panel if they dry on it. Glass House cleans rooftop and ground-mount arrays with water filtered to 0 PPM, meaning no dissolved minerals at all.
Timing is part of the method: cool water on a sun-heated panel can cause heat shock, a sudden temperature change that damages it permanently. Pollen, dust film and bird droppings all come off with pure water and a soft brush, with no chemicals.
NO-SCRATCH, SPOT-FREE FINISH GUARANTEE
Pure-water cleaning is designed to leave your panels free of wash-process spots and scratches.

BLAINE SPECIFICS
What solar panel cleaning means in Blaine
The local conditions that shape how Glass House approaches solar panel cleaning in Blaine, and the standards it holds to on every visit.
WATER
About 310 to 360 PPM
Blaine's water runs about 310 to 360 PPM (parts per million) of hardness, far above the 180 PPM level the USGS calls very hard. Its 17 deep wells feed four plants that remove iron and manganese, but private irrigation wells bypass that treatment. Water that hard dries into white spots on glass and a dull film on siding, and iron from untreated irrigation water oxidizes into orange stains wherever the spray dries. Irrigation spotting from water that hard comes off, provided it has not etched the glass.
WATERING
Odd/even sprinkling all year
Blaine follows an odd/even sprinkling schedule all year and prohibits sprinkling from 10 a.m. to 6 p.m. between May 15 and September 15. Private irrigation wells are exempt. Because those wells can run every day, each cycle that reaches the house leaves another layer of iron and minerals where the spray dries, which is how orange fans build up on siding and driveways. Keep sprinkler spray off ground-mount arrays; every cycle leaves minerals on the glass.
TREES
Oaks, the most plentiful shade tree
Blaine calls oaks its most plentiful neighborhood shade trees and loses hundreds to oak wilt every year. The city is also removing an estimated 1,200 boulevard ash trees because of emerald ash borer. Oak shade keeps roofs and siding damp, which algae and moss need, and oak leaves and catkins fill gutters each year. Dying ash turn brittle and drop limbs onto roofs and into gutters until they are removed. Trees shed pollen and debris onto panels through spring and summer.
WETLANDS
Wetlands and more than 700 ponds
Blaine has more than 700 stormwater ponds and infiltration basins, and the Blaine Wetland Sanctuary covers more than 500 acres of wetland and upland. That much standing water keeps the air around nearby homes humid, so siding, roofs and decks dry slowly after rain and dew. Algae, mildew and moss take hold on surfaces that stay damp, usually starting on the shaded north side. Arrays near water collect more film and bird droppings over the season.

HOW WE CLEAN PANELS
Pure water, soft brushes, top to bottom
Every array is cleaned the same way, in the same order. What sets the method apart is the water and the brush.
WHY NEVER TAP OR HOSE WATER
Water with minerals in it permanently etches a panel, the same way it etches glass. Tap water, hose water and well water all carry those minerals, so nothing touches your panels but 0 PPM water.
01
A quick walk-around first
Every job starts with a look at the array. Carson notes cracks, existing scratches, failed seals and any hard debris before cleaning begins, flags anything that concerns him, and confirms how the panels are reached, from the ground or from the roof.
02
Filter the water to zero
The van carries three reverse osmosis filters, a carbon filter and a deionization filter, which together strip the minerals out of the water. A meter shows what is coming in and what is going out, and the work waits until the water reads 0 PPM.
03
Scrub gently with a solar brush
A brush head made specifically for solar panels goes on the carbon fiber pole, and each panel is scrubbed gently with pure water and no chemicals. The brush loosens pollen, dust film and droppings without scratching the glass.
04
Rinse top to bottom
Pure water rinses each panel from the top edge down, so the loosened pollen, dust and droppings come all the way off instead of settling lower on the glass.
05
Dry spot-free
With no minerals in the rinse water, the panels dry clean and streak-free on their own, with no towels and no wiping. There is nothing in the water to leave a spot behind, which is the whole reason for filtering it to zero.
FOR BLAINE HOMES
What to know before your visit
BEFORE WE COME
Outside spigot on
The filters in the van connect to your outside spigot, so it needs to be on and reachable rather than shut off at the inside valve.
OUTPUT
No promised number
We do not put a number on the power gained after a cleaning, because it depends on the system and on how dirty the panels were.
AT HOME
Kids and pets welcome
Kids and pets are welcome at home during the visit. We ask only that they are not underfoot while the work is underway.
WEATHER
Rescheduling is free
If heat or storms change the plan, rescheduling for weather is always free and never counts as a cancellation.

THE OWNER
The person who quotes your home does the work
Glass House is owned and run by Carson Brenny, with no crews, subcontractors or handoffs. He grew up in Ham Lake, went to Blaine High School and has worked full-time in exterior cleaning for six years. The person who quotes your home is the person who arrives, does the work and walks it with you at the end.
Every job receives the gentlest method that will do the work, because too much force or too strong a mix can cause damage that no cleaning undoes. Every homeowner receives a clear explanation of what is on the house, why the method was chosen and what cleaning can and cannot fix, before any money is spent.
IN CARSON'S WORDS
“It's my neighbors' homes: their biggest investment, one of the places they spend the most time, and where the people they care about most live. It's something everyone should enjoy, and I believe that.”
Carson Brenny, owner

EQUIPMENT AND METHODS
The method panel makers ask for
The same van-mounted reverse osmosis, carbon and deionization filters we use on glass, run until the water reads 0 PPM, feed a brush made only for solar panels on our carbon fiber pole. Each panel is scrubbed gently and rinsed top to bottom so it dries streak-free. Work is scheduled early in the day or under cloud cover, so the water only ever meets a cool panel.
BLAINE QUESTIONS
Solar Panel Cleaning in Blaine: FAQ
When do you clean solar panels in Blaine?
Solar cleaning runs May through September. Each visit is booked for an early morning or an overcast day, when the panels are cool, because the rule is a cool panel rather than a time on the clock. A cloudy afternoon works, and a sunny one does not.
Do you serve all of Blaine?
Yes, every neighborhood in Blaine. Glass House is based in Ham Lake, and Blaine is part of its regular north metro service area, so there is no trip fee. Carson quotes, cleans and walks every job himself, wherever in Blaine your home is.
How do you clean solar panels?
With pure 0 PPM water and brushes made specifically for solar panels. Each panel is scrubbed gently, then rinsed from top to bottom with pure water, so it dries spot-free with no towels. No soaps or chemicals are used, and the work is done only when the panels are cool.
Will cleaning affect my panel warranty?
Our method is the one manufacturers ask for: pure water and dedicated solar brushes, with no pressure, abrasives or chemicals. Glass House follows it to the letter, specifically so your warranty stays protected. Ignoring the manufacturer's cleaning instructions is what puts a panel warranty at risk.
How often should solar panels be cleaned?
Twice a year works well for most homes, for example once in early summer after pollen and cottonwood season and once in September. It is best treated as regular maintenance rather than waiting until the panels look distressed.
Can you remove hard or construction debris from panels?
No. Hard debris and construction debris are not removed from solar panels, because of the risk of scratching the glass and the liability that comes with it. Carson points it out during the walk-around so you know it is there before the cleaning begins.
