Your solar panels deserve to shine every day
Fully automated, cloud-connected pressure cleaning for solar installations. Zero human intervention. Maximum energy yield. Proven results.
The Problem
Dust is silently draining your investment
India's solar boom is real — but inconsistent cleaning is costing plant owners lakhs every year. Here's what's actually happening.
Dust & Soiling Losses
Accumulation of dust, bird droppings, and airborne particles reduces panel efficiency dramatically. Studies confirm output drops by 5–20% — and can be even higher in dry, dusty Indian climates.
Up to 20% output lostManual Cleaning is Risky & Unreliable
Sending workers up rooftops or onto elevated structures is dangerous. Scheduling is inconsistent, quality is variable, and each manual session is a liability and expense.
Safety & liability riskRobots Need Babysitting
Automated cleaning robots sound great — until they break down, fall off panels, or require costly operator intervention and maintenance contracts.
High maintenance costSprinklers Don't Cut It
Existing gravity-fed sprinkler solutions lack sufficient pressure to actually clean panels. They wet the dust and leave a muddy film — often worse than before.
Inadequate cleaningUneven Pressure Across Arrays
When all nozzles open simultaneously, pressure drops significantly for far-end panels. Some panels shine, others remain dirty.
Inconsistent resultsHigh-Rise & Hard-to-Reach Panels
For multi-storey buildings and commercial rooftops, manual cleaning is almost impossible — requiring scaffolding, rope access teams, and lengthy shutdowns.
Access & downtime issuesThe Solution
PanelCrystal — intelligent pressure cleaning, automated
A fully automated, cloud-connected cleaning system that delivers consistent, pressurized water flow across every panel — without human intervention.
Nozzles Grouped by Zone
Nozzles are mounted directly on your panels and grouped into sets of 4–5. Only one group fires at a time — maintaining full water pressure at every nozzle in that group.
Motor Auto-Starts the Cycle
The controller automatically starts the pump motor first, verifies water flow via a flow sensor, then sequentially opens each solenoid valve group for ~40 seconds each.
Sequential Valve Operation
Solenoid valves (controlled via Modbus RS485 relay boards) fire in sequence. Each group cleans thoroughly before the next activates — consistent, effective cleaning across the array.
Schedules + Live Dashboard
Set two cleaning schedules per day, choose which days of the week, and monitor live valve states, motor status, and last cleaning time — from a web dashboard on your phone or PC.
Safety First — Always
Dry-run protection stops the motor if flow is not detected. Emergency stop kills all relays instantly. The RTC-backed clock keeps schedules running through WiFi outages.
Sequential, pressurized cleaning of Solar panels.

System Specs
Controller: SoC + Modbus
Protocol: Modbus RS485
Clock: RTC
Pump: 1–1.5 HP
Interface: WiFi Dashboard
Cloud: VPS Status API
Under the Hood
Built on industrial-grade hardware
Modbus RS485 Relay Board
Industrial Modbus RTU protocol controls solenoid valve relays with precision. Supports up to 50 relays — scales from 10 to 200+ panels effortlessly.
RTC Module
Battery-backed Real-Time Clock ensures cleaning schedules never miss — even during power cuts or WiFi outages. NTP-synced when internet is available.
Flow Sensor Guard
Detects water flow after motor start. If no flow is detected (empty tank / pump failure), the cycle aborts immediately — protecting your pump from dry-run damage.
Cloud Status API
Pushes live status to a VPS endpoint every 5 seconds. View valve states, motor status, and last cleaning time from anywhere in the world.
Responsive Web Dashboard
Access full control via any browser — no app install required. Configure WiFi, set schedules, trigger manual cycles, and hit emergency stop from your phone.
Real Data
Numbers that don't lie
Measured on a real installation: January 2026. System commissioned 10 January — partial-month data extrapolated to a full-month equivalent.
*System installed on Jan 10. Month recorded 5.5 MWh. Since 20 of 31 days were cleaned, extrapolating to 31 days gives ~6.05 MWh equivalent. Actual increase from installation date: +23.5% over the cleaned period.
+12.2%
Conservative month-over-month energy yield improvement (4.9 → 5.5 MWh). Real gain on cleaned days is significantly higher.
+600 kWh
Additional electricity generated in the month PanelCrystal was installed — real money back in your pocket every month.
0 Workers
Zero manual cleaning labour required. Zero rooftop risk. Zero scheduling hassle. The system runs itself.
Why PanelCrystal
Every benefit engineered in
Guaranteed Cleaning Schedule
Two cleaning times per day, configured for any days of the week. The RTC ensures your panels are cleaned on time, every time.
Set & ForgetMore Revenue Per Month
Clean panels produce more electricity. At current grid/net-metering rates, even a 10% yield improvement on a 10 kW system can add ₹1,200–3,000/month.
Direct ROIWater Efficiency
Sequential group firing means maximum pressure at every nozzle, with no water wasted on low-pressure spray.
Eco-ConsciousPump & System Protection
Flow detection aborts the cycle if the water tank is empty. Emergency stop shuts everything down in one click from anywhere.
Always SafeFull Visibility, Anywhere
Live dashboard shows every valve state and motor status. Cloud API pushes updates every 5 seconds.
Remote MonitoringManual Assist Mode
For periodic deep cleans or maintenance, manual mode gives full individual relay control without ripping out the automation.
Hybrid CapableCustomizable to Any Layout
Whether you have 10 panels on a residential roof or 200 on a commercial terrace, PanelCrystal's relay grouping adapts to your layout.
ScalablePIN-Protected Configuration
System configuration is secured with a PIN. Only authorized personnel can change schedules, modes, or network settings.
