The Way we See the PV Market in Lebanon:


Photovoltaic

Systems

Grid Connected

Stand Alone

Public Grid(Net

metering)

Private Grid

(PV/Diesel)

With Batteries (Remote areas, Backup,

Street lighting,..)

Without Batteries

(Special Applications)

Find the Most Adapted Type

for Each Application ?!!!

-Grid Quality-Low Prices

- High lifecycle cost- Short lifetime- Pollution


Concept of a PV Diesel system:

28 ¢/kWh

5 ¢/kWh


The PV system injects power to:


The Public Grid The Diesel Genset Grid

2000MW 1MW>>>∞ ?Is this Solution Technically Feasible?



The PV power is synchronized with the Generators Power:

P PPLoad Gen PV

For a determined load, any variation of the PV power will Directly affect the Power produced by the Generators (indirect

relation)



If the power taken from the PV system is too big:• The generator may work below its minimum acceptable load

• Reverse current will be injected to the Stator of the Generator causing it to act as a load

- Poor Combustion- Deposit forming on turbo and exhaust- Oil and lubricant consumptionReduce Service life

- Stator Will heat and burnDamage the Generator

If the variation of the PV power is big and relatively fast:- Unstable Frequency

- Over/Under Voltage- High Distortion LevelsPoor Grid Quality

• Low spinning reserve: Generators incapable of taking full power of the PV systemComplete Shut Down of the Grid

• Case Study:- Location:- Average Daily Load:

- Available Genset Power:

- Installed PV Power:

- Inverters:

API- Zouk Mosbeh450-600kW

- Power Sources: Only Gensets3 X 635 KVA

- Yearly Diesel Consumption:900 Tons

- Occupied Roof Surface:

192 kWp

1200m²

8 X 20KW



What can this PV System technically achieve?

• 245,000 kWh annual energy yield• 70,000 litters/year of fuel consumption reduction

• 170 tons/year of CO2 emission reduction• 4.6 tons/year of SO2 emission reduction

Cumulative Cash Flow Simu-lation

• Granted By the EU by 5%

• Very Attrative Cash Flow

- 1.075% Interest rate


What about the Economical study of the project?

• The system’s Implementation cost was covered by a NEEREA Loan

- 2 Years Grace Period- 8 Years Loan Period

• The PV Electricity is very cheap: 5¢/kWh Cost (¢/kWh)

- No Down Payment

• Simple Payback 5.9 Years

- Real PBP = 0 Years- NPV= 525,000$- IRR= ∞ %

- Always Positive


- Always Ascending

- 10 Years Total Loan Period

“I now own a half million dollar power plant on the roof of my factory which produces clean and cheap energy… And I did not pay a single penny”


Attractive Performance Very Appealing Economical Results

Technically Safe System

The Tailored Fit PV/Diesel Hybrid Solution Opens New Horizons for Solar Power to Revolutionize the

Lebanese Energy Sector.
