Current Market Situation in China
• China has a population of 1.4 billion people, huge energy resources are
necessary
• Economy is increasing at approximately 9 % per year, therefore energy
demand will grow proportionately
• There is a big dependency on fossil fuels, 55% of which is imported, but
these resources are limited resulting in global warming and high carbon
dioxide emissions

Increasing Energy Demand in China
11
Importance of Renewable Energy
There is a reconsideration into how energy is produced:
• Increasing pressure of environmental protection and energy saving
• More energy independence by using renewable energy
• China's target is to increase its renewable energy share of the energy
market to 15 % by 2020
• Solar energy will make a great contribution

Solar Solutions
Beside on-grid, solar off-grid applications are becoming more popular
as they offer easy and flexible solutions:
• Quick installations, no trenching necessary
• Laborious installation work and investment costs can be decreased
• Flexible and individual solutions
• Reliable system design and long operating lifetime (use of LED lamps)
• More energy independence from fossil energy resources
• Cost and energy saving, eco-friendly, sustainable
13
Applications
Jeff Wu 14.06.12
Ideal for solar street lights and for traffic markets:
• Solar street lights
• Traffic lights
• Signal lights
• Parking meters
• Advertising signs and
billboards

Intelligent Lighting Control in Off-Grid Scenarios
For intelligent and reliable lighting control Phocos has developed a highly
efficient Charge Controller series for lighting applications: The CIS-series
Users benefit from reliable system design with extended lighting time and
special night light features:
• Timer and automatic night light recognition; light can be switched on and off
at sun rise or dawn
• Dual Load or dimming output for two loads or individual dimming settings
• Individual lighting concepts for different needs are available

Features CIS Series
• Robust and fully encapsulated aluminum housing (IP 68), water and dust
resistant, withstands harsh environments
• Works reliably under all climate conditions
• No openings and moving parts like switches or buttons
• Small, compact size, fits anywhere
• Night detection and timer functions, dimming control or dual load outputs
• Infrared remote control programming accessory (CIS-CU)
• Different versions available: CIS-N (negative grounded), CIS-LED (with
integrated LED driver), and CIS-MPPT (with MPPT tracker)

Reliable Highway Monitoring
LocationShandong province, China
ChallengeRemote management of PV operation through RS232
SolutionPhocos installed this PV system to provide solar energy to a highway supervision system for traffic management. Within this system Phocos charge controllers are used to provide information about battery voltage, charging current, etc.

Solar Street Lights as Cost Efficient Solution
Location Beijing rural area, China
Challenge• The project was started in 2006 but
stopped due to high costs • Then it was decided that it would
be able to continue with solar energy
SolutionSince 2006, more than 150.000 solar street lights were installed during the "New Village Construction“ project

22
Solar Street Lights for Rural Regions
LocationKunming, China
Challenge• Low financial budget for village areas• Solar street lamps were installed
directly to the house or gate wall
SolutionThis project provides night-time lightingfor Yunnan villages. Low cost wasimportant due a limited investmentbudget. Direct mounting of the solar systems are a cost-effective solution.

Solar Street Lights for an Important Airport Connector
LocationHeilongjiang province, China
Challenge• Dedicated environmental protection
area • Extreme temperatures in this area
(range from -40 to +60 degrees)
Solution300 solar street lights equipped withPhocos CIS charge controllers havebeen installed along the 9.2-kilometerroad that goes to the importantairport in the Hegang district of Xing´an.

Off-grid solutions in Asia are becoming more popular. Users benefit from:
- Reliable energy availability (in regions without grid connection)
- Independence from fossil fuel energy resources
- Decreased installation costs, no trenching necessary
- Reliable and individual lighting solutions
for example solar street lights, traffic lights, etc.
- Solar street light application increases road safety
at night, also in remote areas
- Sustainable and eco-friendly energy resource
