When light shines on the cell, electrons are pushed out from
the cell, producing direct current electricity.

Connect Cells To Make Modules
•One Silicon Solar Cell produces about 0.5 volts
•36 Cells connected together produce enough voltage to charge 12 volts battery
•50 – 60 cells modules are common for grid connected systems operating at
about 25 - 40 volts each
•Module is the basic building block of systems
•Can connect modules together to get any power configuration (Limited by
voltage)
Solar Cells and Modules currently available in the market:
1. Mono and Poly Crystalline (more than 15% Eff)
2. SunPower/Panasonic HIT®/Ben Q Cell (more than 19% Eff)
3. Thin Film and CIGS (Eff between 8-12%)
6PROPERTY OF SUNERGY SOLAR PTE LTDThursday, March 31, 2016
Mono Crystalline Cells
Poly Crystalline Cells
Able to attain higher efficiency cells compared to Poly and Thin Film.
Appearance of surface is dark and uniform
Highest Module Efficiency in the market at close to 16%
Slightly less efficient compared to Mono Crystalline but higher than Thin Film
Appearance may have inconsistent color
Highest Module Efficiency in the market at 15+%
*Silicon cells are sensitive to heat and temperature.

Factors to be consider before implementation
• Shading
• Direction and Orientation of Module
• Financial Considerations
11PROPERTY OF SUNERGY SOLAR PTE LTDThursday, March 31, 2016
• Shading
– Blocks the sunlight from reaching the module and affect
power generation
• E.g.: Taller buildings might cast a shadow on modules
– Cause the PV string to drop in power (Reason for MPPT)
12PROPERTY OF SUNERGY SOLAR PTE LTDThursday, March 31, 2016
Factors to be consider before implementation
• Orientation and Direction of modules
– To be facing the North or South for maximum exposure to
sun (East to West)
– Angling of module
• Causes Water residue (Shadowing)
• Heat dissipation (heat causes power lost)
• Soiling (Dust and Dirt)
13PROPERTY OF SUNERGY SOLAR PTE LTDThursday, March 31, 2016
Factors to be consider before implementation
Direction of facing affects :
•Hours of sun exposure which may lead to significant power loss
Shading by nearby buildings causes :
• Complete loss of power

Off-Grid Solar and
how it works
Thursday, March 31, 2016 PROPERTY OF SUNERGY SOLAR PTE LTD 19
1. Solar Module to generate power
• Selection of Module depends on Voltage and Ampere
• Size of panel depends on amount needed for charge
• Eg. 12V/24V system requires 18V/36V Panel
• Custom design for 48V system and Hybrid
2. Charge Controller to regulate voltage and current
• Size according to Ampere and voltage configuration
• Eg. Normal or controllers with MPPT
3. Battery to store power
• Storage to be design with backup of 3 – 5 days depending on
requirement
• Battery type eg. Lead Acid or Gel depending on environment
Item needed
Thursday, March 31, 2016 PROPERTY OF SUNERGY SOLAR PTE LTD 20
4. Inverter to convert DC to AC (Optional)
• Inverter selection depend on Load usage and voltage
• Hybrid possible with available onsite generator or other
alternative source of power to charge battery
• Eg. 50W AC Fan requires 50W Inverter with 3x surge factor
Item needed

Why need Off Grid Power
1. Critical in areas of Security (CCTV, Lights and sensors)
2. Backup during power shortage/blackout
3. Used in remote islands where diesel/petrol is expensive
4. Telecommunication/satellite/repeater station
Thursday, March 31, 2016 PROPERTY OF SUNERGY SOLAR PTE LTD 22
Why need Off Grid Power
1. Expensive to install in areas where laying cables is
needed to connect to grid
2. Hard to reach areas accessible by boat or helicopter
3. Backup power for security devices
4. Portable power
Summary,
Power is critical to daily operation. with a reliable backup power
system, we can be assure that our security/safety are not compromised
