Dust, pollen, bird droppings and other build-up can reduce the light reaching your solar panels. Blast Away Guys cleans solar panels on homes and commercial properties across Whangārei and Northland.
We assess the panels and access before choosing a suitable cleaning method. Ask us to include solar panels with your house wash, roof treatment or gutter clear so the work can be planned together.
We use gentle brushing and controlled rinsing suited to the installation. Our purified-water system removes dissolved minerals from the cleaning water, helping reduce mineral spotting as the panels dry.
The cleaning approach needs to suit the panel manufacturer’s care instructions, the condition of the installation and the access available. Tell us about any known damage or specific care requirements when requesting your quote.
There is no single cleaning interval or percentage improvement that applies to every system. The amount of build-up depends on the site.
We can discuss an appropriate maintenance interval after assessing the panels and their surroundings. Cleaning removes surface build-up. It does not repair faults or guarantee a particular increase in electricity generation.
If roof treatment or other exterior cleaning is also booked, we plan the sequence so we leave the panels clean. You do not need to arrange different providers and work out the order yourself.
Compare roof treatment and roof washing or explore combining property-care services.
Every technician who accesses roofs has completed working-at-heights training with relevant NZQA unit standards. We assess the roof, ground conditions and equipment required before work begins.
For lichen, damaged panels or uncertain access, we discuss the appropriate next step before proceeding. We do not promise that cleaning will resolve damage or meet every manufacturer’s warranty conditions.

The automatic dispenser releases metered sprays at a selected interval. It can be set to operate during the day, at night or around the clock. Your printed guide explains setup, placement and replacing the can. Always follow the directions on the spray can.
We don’t recommend it. Solar panels are slippery, often hard to reach, and can be easily scratched or damaged with incorrect tools. It’s safer — and more effective — to let trained technicians handle it.
Typically, every 6 to 12 months. If you live near the coast, in a rural area, or anywhere with dust or high pollen, you may benefit from more frequent cleaning to maximise output.
Tell us about the lichen when requesting your quote. We assess the panels and discuss an approach suited to their condition and manufacturer’s care instructions before proceeding. Established growth and existing damage may limit the result.
We assess the installation and choose a cleaning method suited to the panels, condition and manufacturer’s care instructions. Warranty terms vary by manufacturer and installation. Tell us about specific requirements or known damage before work begins. We do not promise that cleaning preserves every warranty or repairs existing faults.
We assess the panels and access, then choose gentle brushing and controlled rinsing suited to the installation and manufacturer’s care instructions. Our purified-water system helps reduce mineral spotting. We plan roof access and the equipment needed for the site.
Dirty panels can’t absorb as much sunlight, which directly affects your energy output. Dust, pollen, lichen, and grime reduce efficiency over time. Regular cleaning restores performance and helps protect your solar investment.
Choose house washing, roof treatments, bug treatments, chimney sweeping and more, all in one coordinated visit. Ask us to price the services separately and together so you can compare the options.
