Solar market segments: “Solar rooftop” in the GCC means “medium to large commercial & industrial solar systems”
10 kW - 20 MW
• Low CAPEX• Highly variable soft cost• Financing can be
challenging
• Does not require investments in transmission
Commercial & Industrial (C&I)
Utility
>20 MW
• Low CAPEX• Low soft cost• Proven financing model
• Requires significant transmission/grid investment
Residential
3-10 kW
• High installation costs• Very low residential
tariffs in the GCC
• Not economically attractive for installers & the utility

A quick scan of Oman on shows over 200 medium-to-large scale C&I solar opportunities worth 100’s of MWp
Notes:
Attractive C&I opportunities exist in many sectors, including:
o Industrial areas
o Shopping centres
o Oil & gas industry
o RAECO
o …
Total load & roof area is sufficient for several 100
MWp of solar

Notes:
• C&I installed costs are very competitive with those in the utility segment
• In the US specifically, poor regulations made C&I soft costs unnecessarily high
• If regulations are optimized to reduce soft costs, the Oman C&I segment can be as economically attractive as the utility segment
