about SolarDuster

Autonomous. Water-Free. IoT Monitoring. Robotic Cleaner.

SolarDuster is a fully automatic Solar Panel Cleaning technology product by MEMIGHTY. It is a robotic machine with cleaning brushes and it is having an IoT (LoRa) Controller for monitoring and configuring operations of the machine from anywhere in the world.

SolarDuster is described by 3 major components:
  • SolarDuster – The Robot
  • LoRa Gateway
  • Web Panel

1. SolarDuster – The Robot

SolarDuster consists of a solar panel for re-charging its own battery, thus it is fully autonomous in function.

It can detect obstructing object using smart ultrasonic sensors which are used in robot’s auto parking assistance.

It is installed on existing Solar Panels (Solar Panel frame). As per schedule, it runs parallel to the length of the solar panel tables and using the rotating soft nylon brushes it cleans the surface of solar panels. It is a complete water-free cleaning solution.

Real-time IoT Monitoring & Management System

For monitoring SolarDuster – The Robots and remote fault detection, MEMIGHTY has developed LoRa Technology based remote monitoring plugins which can be added with SolarDuster to remotely monitor & manage SolarDuster robotic machines over a Web Panel (Dashboard).

There are 3 components:

1. IoT Controller (in SolarDuster – The Robot)

2. LoRa Gateway

3. Web Panel (Dashboard)

Why LoRa technology?

LoRa (Long Range in kilometers) permits inexpensive, low power and long-range connectivity for Internet of Things (IoT) devices in remote and offshore industries.

How it Works?

The IoT Controller in the SolarDuster robot consists of various data of SolarDuster such as:

  • Battery parameters
  • Forward/reverse cycle operation
  • Schedules
  • Object distance
  • Speed of machine
  • Event history
  • Real-time machine analytics
    1. Solar Panel Voltage
      Charging Status

These parameters are synchronized to the central IoT Gateway at regular intervals using LoRa technology.

  • IoT Gateway is connected to the server/cloud via Internet and sends all SolarDuster data to the Web Panel.
  • A remote monitoring Web Panel is connected to the server/cloud and administrator of the web panel can monitor, configure, control and manage each and alll SolarDuster machines at various sites

Our Features

Water-free Cleaning.

SolarDuster uses brush based dry cleaning method to clean solar panel plants, so no extra requirements of water


SolarDuster fits on existing solar panels frame and as per width of Solar Panel tables.

Remote Monitoring & Management.

With SolarDuster LoRa – IoT based Controllers, Gateways & Web Panel, you can control & monitor your SolarDuster(s) from anywhere in the world using Internet.

Labour-free Cleaning.

Hassle-free 100% automated system for daily cleaning. Zero labour required.

Self-Powered. Solar Powered.

Rechargeable Battery powered machine. Battery is recharged using own solar panel of SolarDuster

Automated Parking Assistance.

SolarDuster consists of smart parking sensors to detect object even at high speeds for detecting end of solar panel row / array.

Auto Fault Detection.

In case of any failures / faults, SolarDuster alerts to the Web Panel for further course of action.

Project Management Methodology

  • Technical Survey of Solar Plant

  • Customize Product Development as per structure layout

  • Delivery as per timeline & Installation

Case Study

The number of SolarDuster implementation depend on the solar power plants layout, some of the examples of SolarDuster implementations are as follows:

1. Horizontal, Long continuous Arrays (Rows)

If the solar power plant is built in a similar kind of a layout as shown by diagram above then N number of SolarDusters are implemented for cleaning of Solar Panel arrays.

2. Horizontal, Long distributed Arrays (Rows)

If the solar power plant is built in a similar kind of a layout as shown by diagram above then N number of SolarDusters are implemented for cleaning of Solar Panel arrays, provided that mechanical joints are to be fabricated to make long, continuous arrays as shown in orange colour lines below.

3. Vertical, Short Continuous Arrays

If the solar power plant is built in a similar kind of a layout as shown by diagram above, then tracks can be made suitable to connect either 2 rows, 3 rows, 4 rows, etc. (as per site requirements) which is as shown below. If the provision of mechanical tracks are made then the number of SolarDusters required shall be (N÷x, where x = number of continuous rows formed by track)
For example: If 3 rows are connected by tracks to form one continuous row / array of Solar Panel table arrays, then SolarDusters required are ‘N÷3’ as shown below.

4. Horizontal, Long distributed Arrays (Rows)

If there is a site where Case-2 and Case-3 are seen together then provisions in both cases must be taken into consideration
