The PV power generation business, requiring long-term development and stable revenue,
is a business which reclaims investment and generates profit through long-term operation of more than 20 years.
Therefore, the ability of O&M company is as important as the stablishment of the power plant which requires stable driving and durability for a long time.
-Implementing preventive inspection of the part vulnerable
to problems of the power plant/p>
- Removing the risks of the power plant in advance
- Conducting state management and maintenance
of power generation facilities
- Capable of tracing inspection of micro cracks (unique in Korea)
- Inspecting the power plant
in real time through remote monitoring
- Analyzing and evaluating the generation data of the power generation system
- Pursuing profit sharing through additional generation amount
as well as guarantee of generation amount
- Pursuing profit sharing through additional generation amount
as well as guarantee of generation amount
- Quickly removing and repairing the defects
of errors or failures
- Preventing recurrence by detecting and analyzing failure
- Inspecting the relevant part and reporting
- Killing weeds within the area of the power plant

- Conducting other electrical work
We optimize the PV power generation efficiency by analyzing accurate and objective data on the causes that lower
the efficiency of the module (hot spot, micro crack, bypass diode et al) through specialized equipment. It is difficult to identify the hot spot,
micro crack et al which lower the efficiency of the module with the naked eye.
We collect and analyze accurate and objective data using specialized equipment.
The diagnosis is conducted with the reverse current method using the luminescence effect which is a feature of the PV cell’s light-emitting diode.
< Inspecting the function of the bypass diode of the module having poor access to the string which can
trace the hot spot of the module without lighting (possible at night time)>

2. Diagnosis of a micro crack
3. Diagnosis of cell damage
4. Diagnosis of screen printing damage
This is a robot system which can clean and diagnose the 1MW-level power plant (panel area: 6,000m2) within 8 hours,
and a set of this system is composed of the main robot and 4 cleaning robots.
It is a practical and highly economical robot which a private person or a maintenance company can use easily by dividing supply and labor
- Minimizing damage of the panel as battery consumption has been minimized and the robot platform has become lighter
by removal through a high-pressure water pump and a brush driving motor
- Ensuring ease on user’s operation through lightweight cleaning/diagnosing robot
- Capable of responding to a PV panel exceeding 4 meters
by additionally composing the vertical guide rail-type movement mechanism
- Maximizing the usability of a single cleaning robot by modularizing the diagnostic test module as a detachable structure
- Enhancing the cost-effectiveness of the robot by modularizing each function of the parts and utilizing common-used parts (battery pack et al)
- The Movement mechanism structure capable of recovering irregular panel arrays
such as a gap and drop between panels and driving even at a panel angle of 45°
- Capable of long panel movement of 50 meters or more with the hose reeling system of the robot itself
- Function of self localization using GPS sensor and encoder sensor
- Precise diagnosis using a high-resolution imaging sensor and a high-sensitivity auditory sensor
- Detailed detection of cleaning status and fault area through precise analysis of the AI (artificial intelligence) algorithm-based large data
- Application of technology for history management and failure prediction of a diagnosed part through the time series analysis
with the diagnosis data acquired in the past
- Capable of cleaning the panel array of 50 meters or longer at a speed of 720m2 per hour with the platform structure
of moving while cleaning the whole PV panel arrays at once
- Capable of operating continually without needing a separate stand-by time for water supplying or battery charging
- Excellent performance in cleaning yellow dust, fine dust, bird’s droppings et al
with high-pressure water spray and control of contact force of the rotary brush
- Capable of applying the robot platform to various panel widths such as 2, 4, 6, or 8 meters
- Capable of system operation in a small-scale power plant or large-scale power generation complex of tens of MWs either
by operating just one unit of the cleaning/diagnosis robot
or simultaneously operating multiple sets of the robot group consisting with one main robot and up to 4 cleaning/diagnosis robots
- The system is supported by a roller attached to the platform at the upper and lower ends of the panel array and moves while working.
The risk of a panel surface damage or platform fall is removed as the system is not influenced by the panel installation angle or the weather such as rain, wind et al.
-Contaminants not removed, cell damage at the upper part of the panel, pattern break, micro crack, hot spot, cable break, and short circuit of a connector et al
*We precisely inspect and detect cell damage on the PV panel, micro crack, pattern break in the panel, micro hot spot et al through
the image processing of video images of up to 1mm resolution and thermal image of up to 2.5mm resolution, and we also precisely receive the sound wave
for a cable break through a microphone voice data analysis, thereby accurately diagnosing a cable or a connector break of more than 2-meter distance
