How many panels

What changes the price
Five things that move the number
02
First clean vs. maintenance
A first clean on panels that have never been done takes longer than keeping already-maintained panels clear. Stay on a regular schedule and the price comes down over time.
03
Roof type and access
A single-storey asphalt roof is quicker than a steep tile roof or a tight two-storey. We work from water-fed poles where we can, which keeps most homes straightforward.
04
Where you are on the island
Coastal, salty roofs and red-dirt leeward roofs foul faster, so they may need doing more often — which is where a maintenance schedule saves money.
05
Add-ons
Bundling bird proofing, gutters or windows on the same visit is cheaper than booking them separately.
Pricing questions
Cost, answered
How much does solar panel cleaning cost per panel on O‘ahu?
On O‘ahu, professional solar panel cleaning typically starts around $15 per panel, and the per-panel rate usually drops on larger arrays and on maintenance visits. The exact figure depends on your panel count, roof and how long it’s been since the last clean — send us the details for a firm quote.
How much is it to clean a whole home solar system?
A typical 20–30 panel home starts from roughly $300 for a first clean, and less once you’re on a regular schedule. Smaller systems start lower, larger ones scale with the panel count. We’ll give you an exact number from a couple of photos.
Does the price go down if I clean regularly?
Yes. Maintained panels are faster to clean than ones with months of baked-on salt, vog or red dirt, so a regular schedule costs less per visit than repeated first-time cleans.
What’s included in the price?
A full pure-water, soft-brush clean of your panels — no chemicals, no residue — and a straight assessment of whether anything else (like bird proofing) needs attention. No hidden call-out fees.
Is professional solar panel cleaning worth the cost?
Dirty panels quietly lose output, and in Hawai‘i’s salt, vog and dust that adds up fast. A clean that costs a few hundred dollars protects thousands of dollars of system and the power it should be producing. For most O‘ahu homes it pays for itself.
