Solar is Less Expensive than Diesel

• PV electricity prices have reduced over 50%

Sources: Diesel Pricing US Energy Information Administration; Solar Pricing: DOE, Lawrence Berkley National Laboratory

• Diesel prices remain highly volatile and have steadily increased

The Global Need for Water Desalination

• The deployment of desalination plants has been led by MENA

— ~2,800 desalination plants produce 27M m³/day of water

— ~ 38% of the global capacity

• It is estimated that only 0.8% of global desalination capacity is currently supplemented by solar power

Saudi Roll-out & Phases of Development

King Abdullah Initiative for Solar Desalination

Building a desalination plant with a production capacity of three hundred thousand cubic meters per day (300,000m³/day) at a site that will be chosen later. The implementation period for this is three years, and will start after the completion of the first phase.

PHASE II (2013–2015)

Building a desalination plant with a capacity of thirty thousand cubic meters per day (30,000m³/day) to meet the needs of one hundred thousand dweller of Al-Khafji City (Arabian Gulf). Power an RO Plane from a solar energy farm.

PHASE I (2010–2013)

The implementation of several water desalination plants using solar energy in various locations of the Kingdom. This phase will start after the completion of second phase.

PHASE III (2016–2018)

Common Desalination Technology Types Two Broad Categories of Desalination Technologies

1. Thermal Desalination Technologies use heat to vaporize water

— Multi Stage Flash (MSF)

— Multi Effect Distillation (MED)

— Vapor Compression (VC)

2. Non-thermal Desalination Technologies use membrane based methods for water desalinations

— Reverse Osmosis (RO)

— Electrodialysis (ED)

Almost 80% of the world’s desalination capacity is provided by MSF & RO

Module Performance – Comparison to c-Si

Shaded Area

Min.

Short side of module

Robust against shading in landscape orientation (perpendicular to cells)

FSLR Power loss is ~proportional to shading: 10% shading = ~10% output power loss

Typical c-Si Power loss: 10% shading = ~30% output power loss

Minimizes early morning and late evening energy loss while allowing row spacing (array

footprint) to be minimized

Solar Energy Energy Efficiency

1- Raising awareness Campaigns → weak without higher energy rates

2- Adopt energy efficiency measures & upgrade units & refurbishments → Costly

3- Harnessing solar PV → Achieves net effect of all previous methods

How do we reduce energy consumption in buildings?

Building 79%

Agriculture 3%

Industrial 18%

Energy Consumption in Saudi Arabia

Governmental 15.1%

Commercial 12.2%

Solar Peak Shaving resembles Solar Demand Side Management (SDSM)

•NO need for smart Metering devices

•NO need for permitting from utility company

•System is integrated in harmony with grid, No grid impact or stability issues

•Solar PV yield energy efficiency targets, with fast, cost effective and easy implementation

•Reduces electricity bill, energy consumption & carbon emissions

•Peak Shaving requires less space

How do we reduce energy consumption in buildings?

Merits:

“Peak shaving allows for additional capacity by freeing up peak demand”

No export meter

• PROS • CONS

• CSP advocates frame their value proposition in terms of green energy first, cost second.

• PV + Fuel hybrid systems have 24/7 capability, lower capital costs and LCOE, and displace 20% - 50% of the fuel vs. fuel alone approaches (depending on the application)

• LCOE for a CSP system with storage is at least 40% higher than PV and requires large scale projects > 60 MW to allow for economies of scale, etc.

• To win the cost debate CSP advocates push the 24/7 nature of their technology and argue that PV + battery (or other) storage is just as expensive as CSP

• Storage systems for CSP are still unproven experiments and have not been industrially scaled.

• Thermal heat storage comes at an added cost in terms of oversizing the solar field and adding storage tanks, aside from molten salt management

• Easier to localize as most BOM already existing in local industry

• Inherent heat storage • Allows for dispatch ability

• CSP BOM has specialized technology that requires knowhow that may not exist in local industry like concave mirrors etc. There is not value add to local industry otherwise

Typical Pro-CSP Argument vs. Cons. For internal use Only
