Solar Panel Cleaning Robot Row-Transfer Docking, CRADYL

What is Taypro CRADYL?
Taypro CRADYL is an autonomous mobility platform for solar panel cleaning robots. It is installed on dedicated railing tracks at the end of solar panel rows and transfers a cleaning robot from one row to another without manual lift-and-shift, unlocking multi-row coverage with a single robot where buying one robot per block is not economical.
The docking station uses rail-based linear travel along precision-aligned end-row tracks supported by RCC or ballast foundations. An integrated solar panel charges the lithium-ion battery, supporting continuous daily operations under standard daylight. Sensor-guided positioning aligns CRADYL precisely with each target row before secure pick-up and drop-off of the cleaning robot.
CRADYL is shipping today across India and integrates with Taypro cleaning robots including HELYX semi-automatic robots, GLYDE automatic robots, and compatible GLYDE fleets. Movement, charge level, and sensor data are visible in the NECTYR cloud portal alongside your existing robot schedules.

How does CRADYL transfer a cleaning robot between rows?
Once railing is installed and aligned at row ends, CRADYL automates the full pick-up, transit, alignment, and redeployment cycle with no panel modifications required.
Robot completes cleaning and returns to CRADYL
When a solar row cleaning cycle finishes, the Taypro cleaning robot returns to the CRADYL docking station at the end of the row and drives into the cradle for secure locking before transit.
Docking and locking for transit
CRADYL secures the robot in the docking cradle with sensor-verified locking, protecting the unit during rail travel and in high-wind conditions when stationary.
Rail navigation to the next row
The self-propelled platform travels along end-row railing tracks at up to 5 metres per minute to the next designated row, with edge-detection sensors preventing derailment.
Sensor-guided alignment with the target row
Integrated sensors stop CRADYL precisely aligned with the new row endpoints so the cleaning robot can deploy onto the correct module line without operator adjustment.
Undocking and redeployment on the new row
The robot is released from the cradle to continue its waterless cleaning cycle on the new row while CRADYL waits for the next transfer or returns per your fleet schedule.
Cloud scheduling and fleet visibility
Movement, position, charge level, and fault diagnostics are scheduled and monitored through the remote portal with LTE and Wi-Fi connectivity, repeating per your plant cleaning programme.

How CRADYL is installed on your plant
Typical deployment follows Taypro's movable docking station installation methodology used on live Indian utility sites.
- End-row railing tracks are mounted on columns fixed to the ground with RCC foundations or ballast, depending on geotechnical conditions.
- Column height and alignment are managed so rail travel remains smooth and level across the transfer path.
- The CRADYL unit is placed on the aligned track and connected to the robot control and cloud monitoring system.
- No modifications are required on solar modules, enabling quick, modular setup once civil and rail work is complete.

Why automate row-to-row robot transfer?
Manual lift-and-shift between scattered blocks consumes crew time, slows cleaning cycles, and increases safety and damage risk compared with autonomous docking.
| Criterion | Manual row transfer | Taypro CRADYL |
|---|---|---|
| Labour per transfer | Crew lift-and-shift between rows or blocks | Hands-free autonomous docking and rail travel |
| Transfer time | Variable; depends on crew availability and distance | Scheduled rail transit up to 5 m/min on aligned tracks |
| Robot utilisation | Robot idle during moves; fewer rows per shift | One robot services more rows per shift |
| Safety and damage risk | Higher drop, scratch, and handling risk | Secure cradle locking and sensor-guided alignment |
| CAPEX strategy | Often leads to buying more robots per block | Extends one robot across scattered layouts |
| Fleet visibility | Little telemetry on inter-row moves | Position, charge, and faults in cloud portal |
| Wind and weather | Ad-hoc handling in harsh conditions | IP65 enclosure; high wind rating when docked |
| Scattered plant fit | Labour cost scales with blocks and roads | Purpose-built for gaps between non-contiguous arrays |
CRADYL vs buying another cleaning robot
On scattered plants, transfer automation can defer an extra robot purchase while preserving multi-row coverage.
| Criterion | CRADYL docking | Additional cleaning robot |
|---|---|---|
| Upfront investment | Docking station + end-row rail civil works | Full robot capex per block or row group |
| Rows covered per robot | Multi-row via autonomous transfer | One contiguous row group per unit |
| Labour for moves | Minimal; cloud-scheduled transfers | Zero if fully automatic per array; high if semi-auto pick-and-place |
| Best plant type | Scattered blocks, roads, irregular spacing | Contiguous arrays with dedicated assignment |
| Pairs with | HELYX, GLYDE, GLYDE fleets | Standalone cleaning per array |
| Monitoring | Transfer status in NECTYR | Standard robot cleaning telemetry |
| Payback driver | Avoided second robot + labour savings | Extra MW cleaned per day on one block |
| When to choose | Gaps between rows; one robot under-utilised across site | Large contiguous plant; labour-free daily autonomy needed |
Where CRADYL fits best on Indian solar plants
Scattered utility blocks
Multi-block plants where rows are separated by roads, drainage, or buffer land and one robot cannot traverse continuously.
Semi-automatic robot fleets
Sites running HELYX or similar pick-and-place robots that need faster inter-row movement without adding headcount.
CAPEX optimisation programmes
Owners who want autonomous cleaning coverage but need to defer buying additional robots until transfer automation proves ROI.
Utility-scale retrofit programmes
Existing Taypro robot deployments where end-row rail and CRADYL extend reach without replacing the cleaning robot fleet.
Built for Indian utility-scale scattered plants
Dust, heat, wind, and water-scarce O&M realities across Rajasthan, Gujarat, Karnataka, and Tamil Nadu portfolios where scattered blocks are common.
High-soiling scattered portfolios
When blocks cannot be cleaned as one continuous array, CRADYL keeps one robot productive across more rows per day instead of idling during manual moves.

Frequently asked questions
CRADYL is Taypro's autonomous row-transfer movable docking station — a battery-powered platform on end-row rails that moves a solar cleaning robot between rows. It is the fleet-integrated platform name used on taypro.in today.
After a row is cleaned, the robot returns to CRADYL and locks into the cradle. CRADYL travels along end-row railing to the next row, aligns using integrated sensors, releases the robot to clean the new row, and repeats on schedule. Movement and status are visible in the cloud monitoring portal with LTE or Wi-Fi connectivity.
CRADYL is designed for Taypro GLYDE and compatible Taypro cleaning robots, including fleets already using HELYX semi-automatic pick-and-place robots and GLYDE automatic robots on scattered or multi-block layouts. Confirm rail layout, row spacing, and robot model with Taypro engineering before procurement.
No modifications to solar modules are required. Installation uses dedicated end-row railing tracks on columns fixed with RCC foundations or ballast. Once rails are aligned, the CRADYL unit is placed on the track and connected to robot control and cloud systems.
CRADYL is a launched Taypro product shipping for Indian utility-scale plants. It is not a roadmap or pilot-only offering. Contact Taypro with your plant layout for integration planning, compatibility confirmation, and commercial quotation.
Representative specifications include a 1000 mm × 4000 mm footprint, 220 kg weight, rail-based travel up to 5 m/min, solar-charged lithium-ion battery, IP65 rating, LTE/Wi-Fi cloud connectivity, up to 180 km/h wind resistance when docked, 40 km/h in motion, 18° max slope, and 90°C max operating temperature. Site-specific rail design may adjust details.
CRADYL is strongest on scattered plants where one robot could clean more rows if transfers were automated, but buying a second robot for each non-contiguous block is uneconomical. If you have large contiguous arrays needing daily unattended cleaning, a fully automatic robot such as GLYDE may be the primary answer; CRADYL complements scattered layouts.
CRADYL integrates with Taypro's remote monitoring platform. Operators can schedule movement, track position, and review sensor data and battery charge levels in the cloud portal alongside existing robot cleaning schedules on NECTYR.
Taypro performs scheduled preventive maintenance on docking stations and rails, provides remote diagnostics through the cloud system, and targets same-day on-site intervention across India when physical service is required, consistent with Taypro's robot fleet AMC and support model.
Pricing depends on number of transfer paths, rail civil scope, robot models in use, and AMC coverage. Share MW capacity, row spacing, block layout, and current robot fleet with Taypro for a site-specific quote and deployment plan.
