What Shire Oak International does
Shire Oak International is a renewable energy developer and financier specializing in solar rooftop solutions for commercial and industrial clients, primarily in Vietnam. Founded in 2002 by Mark Shorrock and headquartered in Ho Chi Minh City, the company originated as a developer of large-scale renewable projects in the UK and Europe — including the UK's largest solar farm and the world's first 320MW lake solar farm at Swansea Bay — before establishing Vietnam as its Asia regional hub in 2019. It has since accumulated 110+ projects with 650MW of planned or installed capacity and approximately $190 million in cumulative investment.
The company's core offerings are Rooftop Solar Leasing Contracts and Power Purchase Agreements (PPAs), both supported by full Operations and Maintenance (O&M) services and 25-year panel warranties. Under the PPA model, Shire Oak funds 100% of design, materials, and installation; customers purchase generated electricity at rates 5–15% below EVN grid prices, with excess electricity sold back to EVN on a revenue-sharing basis. The Rooftop Lease model involves leasing factory rooftops and selling generated electricity directly to the grid. Both contracts run 15–20 years, after which system ownership transfers to the customer. Tier 1 solar panels are sourced from manufacturers in Europe, North America, and Asia.
Shire Oak serves primarily manufacturing and industrial facilities in Vietnam — including footwear (Tata Coffee Vietnam, HWASEUNG), furniture (Boho Décor, Mekong Furniture), automotive (Toyota Boshoku), textile, seafood, and packaging firms — alongside select government institutions. Distribution combines direct enterprise sales with industrial zone partnerships (IMC, Bao Minh, PebSteel) and a 10+ EPC contractor network (Vu Phong Solar, Solar Electric Vietnam, Reecons). The company has expanded internationally with independent solar farms in Zimbabwe, Uganda, Colombia, Iraq, and Vietnam, and maintains a team of 50+ employees across 11 nationalities.

Shire Oak International product offering
Product offeringCore offering
Shire Oak International finances, designs, installs, and operates rooftop solar photovoltaic (PV) systems on commercial and industrial facilities in Vietnam under Power Purchase Agreements (PPAs) and rooftop leasing contracts of 15–20 years. The company covers 100% of consulting, equipment, installation, and ongoing operations and maintenance costs, selling generated electricity to customers at discounted rates versus the EVN grid and transferring system ownership at contract end. Targeted outcomes include approximately 15% electricity bill reduction and 5–7°C factory temperature reduction for customers.
Product overview
Shire Oak International is a renewable energy developer and financier specializing in solar rooftop solutions for commercial and industrial clients. The company operates two core models: (1) Rooftop Solar Leasing Contracts, where Shire Oak installs and maintains solar systems on factory rooftops, bearing all upfront costs while customers pay discounted electricity rates over 15-20 year terms with full ownership transferring upon completion; and (2) Power Purchase Agreements (PPAs), where the company fully invests in solar installations and customers purchase generated electricity at rates below grid prices, with profit-sharing for excess energy fed back to the grid. Both offerings are supported by comprehensive Operations and Maintenance (O&M) services with long-term warranties. Shire Oak uses only Tier 1 solar panels sourced from manufacturers in Europe, North America, and Asia.

Products and services
- Rooftop Solar Leasing Contract Shire Oak International leases the rooftop of a factory or industrial facility, installs a solar PV system at its own cost, and operates and maintains the system over a 15–20 year lease term. The customer pays discounted electricity rates during the contract and takes ownership of the solar system for a nominal fee at the end of the lease, while Shire Oak retains full responsibility for installation, operations, and maintenance throughout.
- Power Purchase Agreement (PPA) Shire Oak International finances, designs, installs, and owns a rooftop solar PV system on a customer's facility under a 15–20 year Power Purchase Agreement. The customer purchases the generated electricity at a rate below EVN (Vietnam Electricity) grid prices, with two pricing options: a 5% discount on EVN rates for a 15-year term or a 10% discount for a 20-year term; or alternatively a fixed electricity rate of $0.095/kWh for 15 years or $0.085/kWh for 20 years. Excess electricity exported to the grid is sold back to EVN with revenue shared between Shire Oak and the customer.
- Operations and Maintenance (O&M) Support Shire Oak International provides full operations and maintenance support over the 25–30 year lifetime of installed rooftop solar systems, including performance guarantees, a 25-year power output warranty on Tier 1 solar panels, and inverter coverage. The O&M service is bundled with both the Rooftop Solar Leasing Contract and PPA offerings, ensuring long-term durability and performance of customer installations.
