MARAFIQ 3

• Power and Water Utility Company for Jubail and Yanbu • Private joint-stock utility company established under Royal

Decree in October 2000 • Officially started operations on 1 January 2003 • Multi-utility: one-stop shop for existing and new users

4

• Power Generation, Transmission and Distribution • Seawater Cooling • Desalination (Process Water and Potable Water) • Industrial & Sanitary Wastewater Treatments • Irrigation Water and Reclaimed Water • Sales Gas distribution to Light Industries

MARAFIQ

OBJECTIVE

Introduce the regulations set by ECRA for the Small-Scale Solar PV Systems as well as its benefits to the consumers.

5

• New regulations issued for Small-Scale Solar PV Systems.

• Will come into force on July 1, 2018. • As part of Vision 2030, ECRA aims to

create an encouraging environment. • Saudi Arabia targets to generate

around 9.5 GW of electricity from such sources.

• Vital step forward towards the realization of the deployment of renewable energy in Saudi Arabia.

INTRODUCTION

• Solar Panels : Convert sunrays into electricity.

• Inverter: Converts electricity from DC to AC (grid voltage).

KEY FACTORS FOR SOLAR PERFORMANCE

• Irradiance: Is a measure of the amount of sunlight falling on a surface.

• Temperature: The warmer the solar cells get, the less efficient they are!

• Shading: Shading has a large effect on solar cells efficiency so solar panels should be located such that there will be no shadows on them.

• Soiling: Dirty solar panels produce less electricity.

SAUDI ARABIA SOLAR MAP 10

Average Range of expected generated electricity by Solar PV in Yanbu

15-32 kWh/m2/month

Average Range of expected generated electricity by Solar PV in Jubail

14-30 kWh/m2/month

Typical System Losses 14% (Soiling, shading, mismatches, wiring, connections, nameplate rating, availability)

Typical range of DC-to-AC Size ratio 1.10 to 1.25

Range of PV module efficiencies available in the market

12.4 % - 22.2%

HELPFUL FIGURES

SOLAR PANEL EFFICIENCIES BY MANUFACTURER 12

Eligibility: • Be a customer of the DSP • System to be connected to

Distribution System • Not less than 1kW and not

exceed 2000kW in one premises.

• Not exceed aggregated capacity of 5000kW (for the same consumer at different premises in one distribution system)

13 SUMMARY OF ECRA REGULATIONS FOR SMALL-SCALE SOLAR PV SYSTEM

Limitations: • Not exceed the connected

load. • Not exceed 3 % of the

preceding year peak load within the distribution operating area.

• Not exceed 15 % of the rated capacity of the transformer.

14 SUMMARY OF ECRA REGULATIONS FOR SMALL-SCALE SOLAR PV SYSTEM

Required Metering Arrangement: • First Meter (Main Meter) Bidirectional meter Measures energy injected

and consumed DSP bears the cost of meter.

• Second Meter Applicable if capacity

exceeds 100kW. Measures energy generated

by the PV system. Consumer bears the cost of

such meter. Net Metering

Arrangement allowing you to receive credit for surplus energy sent to grid through a bi-directional energy meter.

15 SUMMARY OF ECRA REGULATIONS FOR SMALL-SCALE SOLAR PV SYSTEM

• Consumer energy bill reduces. • Generation is during day time

when demand is more. • Solar generation on vacations is

not wasted since it is sent to the grid and credit is given.

• No need for batteries. • Utilizes idle roofs, open spaces etc. • Generation of environmentally

clean energy. • Allows small consumers to take

benefit of and participate in renewable energy generation.
