PRODUCTS · FK SERIES
Solar Panel Cleaning Robot
The Doka FK series — designed and manufactured in Turkey — helps reduce soiling-related output losses in PV plants when used as part of a regular cleaning program. FK-1000-V3 is suitable for rooftop PV and large sites when higher capacity is needed; FK-600-V2 is the more compact option for rooftop PV, mid-scale sites and narrow access areas.

Benefits of Robotic Panel Cleaning
Unlike manual cleaning, robotic cleaning applies uniform pressure on the panel surface, prevents scratching and delivers a standardized result. Labor cost drops by up to 60%; cleaning time per panel falls from 5 minutes to 30 seconds.
01 · YIELD
1800 m²/h Cleaning Capacity
Dust, pollen and bird droppings can cut output up to 18% in 30 days. Regular robotic cleaning keeps that loss near zero.
02 · PROTECTION
Extends Panel Life
Imported Nylon 6.6 soft brushes do not scratch the surface. Prevents permanent damage from acidic residues.
03 · OPERATION
Single-Operator Run
A 100-meter remote lets one operator clean safely and quickly. Working-at-height risk drops to zero.
04 · FLEXIBILITY
Dry, Wet & Hybrid Modes
Wet mode where water is available; dry brushing for desert or remote sites. 6—30 L/min adjustable flow.
05 · DURABILITY
−30 °C / +50 °C Operation
A working temperature range that fits every climate zone — from Eastern Turkey to the Mediterranean coast.
06 · SAFETY
Edge-Detection Sensor (FK-1000-V3)
Optical sensors detect panel edges and prevent the robot from falling. Enables unattended operation in semi-auto mode.
Hardware Details
Hardware details that set the FK series apart in the field — small touches that matter at scale:
BRUSH
Dual Roller and Strip Brushes
Counter-rotating dual roller brushes front and rear, plus side strip brushes. Two-directional cleaning in a single pass; no residue.
APP
Battery Monitoring via Mobile App
Track battery capacity, charge status and runtime live from a mobile app. Field planning becomes simple.
SAFETY
Dual Emergency Stop
Emergency stop buttons on both the remote control and the robot itself. Two points to halt immediately when needed.
Applications
📌 Solar Power Plants (PV)
On megawatt-scale PV sites, regular cleaning shortens payback time. FK-1000-V3 covers a 5 MW site in 2-3 days at 1800 m²/h. We prepare a turnkey maintenance plan.
📌 Rooftop PV Systems
Roof-mounted PV systems on factories, logistics facilities and shopping malls pose safety risks during cleaning. FK-1000-V3 is preferred for higher-capacity rooftop cleaning; FK-600-V2 is the more compact choice for tighter access areas.
📌 Agriculture & Livestock Facilities
Agri-PV sites face heavy dust, pollen and organic residue. Harvest-season soiling can reduce output by up to 30%. We design seasonal cleaning programs.
📌 Industrial Zones
24/7 field support for PV plants in industrial parks. Our Eskişehir-based team reaches anywhere in Turkey within 48 hours.

Frequently Asked Questions
What is a solar panel cleaning robot and how does it work?
A solar panel cleaning robot is an autonomous machine that removes dust, pollen and bird droppings from PV panel surfaces using soft brushes controlled by a remote. The Doka FK series uses a 2.4 GHz 100-meter remote, imported Nylon 6.6 brushes and optional water spray. A single operator can clean up to 1800 m² per hour.
How much does a solar panel cleaning robot cost?
Pricing depends on brush span (1000 mm / 600 mm), semi-automatic mode, edge-detection sensors and warranty coverage. We want to provide a tailored quote based on your panel count and site geography — fill out our demo form and our field engineer will respond the same day. See our 2026 pricing guide for a detailed analysis.
How often should solar panels be cleaned?
Depends on geography: every 15 days in desert and industrial zones, monthly in rural areas, every 2-3 months in coastal regions. Rule of thumb: after a 30-day rain-free period, yield loss reaches 15-18%; cleaning is essential before this point. See our cleaning frequency guide.
Does robotic cleaning damage solar panels?
No. Doka FK series robots use imported Nylon 6.6 soft brushes; they do not damage the panel's anti-reflective coating. The robot's weight (26 kg) distributed across panels applies less pressure than manual cleaning. Quality and safety certifications are in place.
What should solar panels be cleaned with?
Pure or osmosis water is the safest method. Tap water contains lime that can leave marks. Detergent or chemicals damage the anti-reflective coating — do not use. Doka robots run in dry, wet and hybrid modes with 6-30 L/min adjustable flow.
What happens if solar panels stay dirty?
Dust, pollen and bird droppings block sunlight from reaching the PV cells. In 30 days, output can drop 15-25%. Acidic bird droppings and industrial residue permanently erode the surface; panel life shortens. Regular robotic cleaning protects both production and panel warranty.
What's the difference between FK-1000-V3 and FK-600-V2?
FK-1000-V3 and FK-600-V2 can both be used on rooftop PV systems. FK-1000-V3 is the easily portable, higher-capacity model: 1000 mm brush, 1800 m²/h speed, semi-automatic mode and edge-detection sensors. FK-600-V2 is the more compact option: 600 mm brush, 1080 m²/h and lighter weight. Both use the same battery, motor and remote-control platform.
Can the robot be used on rooftop PV systems?
Yes. FK-1000-V3 and FK-600-V2 can both be used on rooftop PV systems. FK-1000-V3 is easy to carry for high-capacity rooftop cleaning; FK-600-V2 is more compact for narrow access areas. Modular design enables fast setup; the 17° climbing angle suits tilted rooftop PV applications.
