Expected ROI of rooftop solar battery project in Saudi Arabia 2026

How much does solar PV cost in Saudi Arabia?

In September 2021, the LCOE of rooftop PV systems in Saudi Arabia ranged from 0.05 to 0.08 $/kWh. By 2020, the installed solar PV capacity in Saudi Arabia had grown to 5.6 GW, with distributed solar PV systems, including rooftops, accounting for 2.6 GW of this total capacity.

How much electricity does a rooftop PV system save in Saudi Arabia?

Initial rooftop PV system utilisation factors ranged from 21 % to 49 %. Average electricity savings for buildings in Saudi Arabia are approximately 35 %. Performance ratios range from 77 % to 84.27 % across various regions. The resulting mean LCOE for rooftop PV systems is $0.0445 per kWh.

What is the LCOE for rooftop PV systems in Saudi Arabia?

Levelized cost of electricity of distributed PV systems The LCOE for rooftop PV systems in Saudi Arabia can fluctuate based on several factors, including system size, PV module type, location, installation expenses, and financial arrangements.

What are the climate challenges faced by rooftop PV systems in Saudi Arabia?

Rooftop PV systems in Saudi Arabia face climate challenges, such as extreme heat, dust, sandstorms, humidity-related corrosion, intense sunlight, and low rainfall, affecting their efficiency and performance [, , ].

What is the optimal orientation for solar panels in Saudi Arabia?

The focus has been on optimal azimuth and tilt angles in Saudi Arabia and desert regions to determine the optimal orientation for installing PV modules on rooftops and urban areas to optimise PV power generation. PV systems are strategically positioned and angled to maximise their exposure to solar radiation .

What is the performance ratio of PV systems in Saudi Arabia?

Performance ratio of PV systems The PR of PV systems in Saudi Arabia varies due to factors like location, orientation, shading, and PV module quality. However, the country's abundant solar resources and favourable climate enable high PRs. Previous studies show PRs ranging from 77.00 % to 84.27 %, as shown in Fig. 11.
