Preface

  

Airborne dust particles, sticky tree and plant sap, lichen, soot and bird droppings are just a few of the things that can contribute to a build-up of dirt on your panels. Accumulation creates shading and therefore will prevent sunlight reaching the cells. This results in poor system performance, loss of efficiency and a loss of financial return for the owner and investor of solar energy. Various reports mention losses of up to 10% to 25% in electricity generation as a result of dirt. Most of the time modules are not cleaned regularly due to 

  1. Unavailability of skilled manpower
  2. Non accessibility to panel areas
  3. Risk in Climbing high rooftops

Performance Statistics

  1.  Min. Cleaning wattage/day - 1.04 MW/Day/robot
  2. Optimum   Cleaning Target/day - 3456 Panels/day/  Robot 
  3. Robot Cost/Gross Merchandise   MWp**- 350/-  *at peak utilisation  
  4. Module Cleaning  Cost / Panel ( Gross Merchandise) - 0.20/-   to 0.30/- /panel  at peak utilisation

*Peak Utilisation of the cleaning frequency is selected such a way that Robot is used for min 4 Hrs per day for min 26 days of a month.**Gross Merchandise MW is total amount of MW that needs to be cleaned in 3 years taking into consideration frequency of cleaning. Modules are assumed to be of 300 Watts# The cost of Robot mentioned above is indicative and has variances based on size of the plant, cleaning frequency and % utilization. It also does not take care of other cost associated with module cleaning like operating manpower, water, electricity etc.

Robotic Module Cleaning System

Jetsons Robotic module cleaning system offers variety of models that supports various needs of the customer. 

Modular Robots for Module Cleaning

Jetsons Robotics has devised new family of Robots which are modular to adjust various Row heights depending on customer site requirements. Current model supports 2M, 4M, 6M without losing any of it's flavor of portability.

How does modular Robot works ?

Standard robotics system of 2M row height is fixed on movable chassis. The chassis height can be selected based on the Row height requirements of the specific solar project. Entire chassis moves on the Module table and cleans 2-M height in one pass. 

  

  1. Modular Robot offers complete flexibility on the table row height, right from 2-M, 4-M, 6-M. 
  2. 2-M cleaning robot is fixed along with Chassis to support 4-M or 6-M length.
  3. Robot cleans 2-M height row in one pass. 
  4. Robot makes 2 or 3 passes for cleaning 4-M and 6-M row height respectively.
  5. Cleaning speed reduces to 1/2 , 1/3 as row height increases to 4-M & 6-M respectively, 
  6. Cleaning Robot is manually adjusted for upper or bottom row before cleaning cycle is started. 
  7. The chassis can be moved from one table easily. 

Benefits of Modular Design

  1. Since the Robots used in this system is of standard 2M length, customer can use Robotic system for cleaning 2M, 4M, 6M row heights by choosing appropriate chassis. 
  2. Even the Solar projects having combination of Row heights can be supported using multiple chassis. 
  3. Chassis being light weight, the entire unit is portable from one table to another irrespective of the Row height.

Water Distribution System

image82

Water distribution system involves pumping unit, HDPE pipeline and quick release valves. 

  1. Pumping Unit - The unit comprises of precise design of water pumps ( monoblock or vertical inline ) to offer end point pressure of 4 BAR. The unit is protected with motor over running due to lack of water and over current. The control panel ensure smooth start of pump.
  2. The pipeline is designed such a way that water reaches to all the modules with least resistance. Either PVC or HDPE pipes are used for the distribution. HDPE pipes are joined with compression fittings for longer durability.
  3.  At strategic point brass quick release valves are used along with swivel based and service saddle to connect hose easily. 

Water Treatment System

Reverse Osmotic water treatment  system is custom-made packaged unit to treat all types of water problems. It can be easily installed for diverse residential, commercial and industrial application.  The system is designed for TDS ( total dissolved solids )  of 1500 ppm. However, the system can be redesigned as per the water analysis provided by the client.

The standard sizes available are 500 / 1000 / 1500 / 2000 Ltr/hr. 

Zincalume based Water Storage System

image84

 We use  storage tanks made out of Zincalume sheets for the water storage, for module cleaning services. 

Zincalume steel has an alloy coating  with 150 / 1100 gram/m2 coating  equally on both sides of the coated strip. These sheets worldwide have set the standard for corrosion resistance and long life and are manufactured as per Australian Standard AS 1397:2002, American Standard ASTM A792M and Indian Standards IS 15961:2012 & ISO 9364. Zincalume steel has the following major advantages over Zinc Galvanized sheets in the same environmental conditions: Zincalume steel delivers outstanding durability, with a lifetime up to four times that of ordinary galvanized steel against corrosion. 

The sizes of the tank are custom built
