• 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.

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.

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)

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
![Page 16: Small-Scale Solar PV Systems New Regulationscdn-cms.f-static.com/uploads/350761/normal_5a27d2b17374c.pdf · The warmer the solar cells get, the less efficient they are! • Shading:](https://reader035.fdocuments.us/reader035/viewer/2022071012/5fca864195e30b400028ceb1/html5/thumbnails/16.jpg)
• 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.
