SUN Energy

What SUN Energy does

SUN Energy is an Indonesia-headquartered, Singapore-registered solar energy project developer founded in 2016 that designs, finances, installs, and operates commercial and industrial (C&I) solar photovoltaic systems across the Asia-Pacific region. The company offers a 'Sustainability-as-a-Service' platform with three financing structures — SUN Purchase (direct ownership), SUN Rental (15-25 year rental with zero CAPEX), and SUN Leasing (3-6 year financing with end-of-term ownership transfer) — supported by an IoT-based monitoring system, O&M services, and a DP 0% zero-down-payment option. As of January 2026, SUN Energy operates 420 MW of solar capacity across four countries (Indonesia, Thailand, Australia, Taiwan), has completed 350+ projects for 60+ enterprise clients spanning 20+ industrial sectors, and has offices in Central Jakarta, Semarang, Surabaya, Singapore, and Ho Chi Minh City.

The company has expanded beyond standalone solar into integrated energy solutions, including Battery Energy Storage Systems (BESS), Smart Micro Grid technology developed with Huawei Indonesia (December 2023 partnership), and proprietary innovations such as Indonesia's first Containerized BESS (deployed at coal miner PT Cipta Kridatama) and the portable Solar PV Roll Up system (deployed at Berau Coal). Revenue is generated through one-time project fees (SUN Purchase), long-duration subscription contracts (SUN Rental/SUN Leasing with maintenance included), and ongoing O&M service contracts. Capital raised totals at least US$57 million across a November 2021 US$25M Series A led by TBS Energy Utama and a February 2024 follow-on round led by DEG with PermataBank participation, supporting the company's stated targets of 2 GW operational capacity by 2025 and broader energy solutions expansion.

SUN Energy sells through direct enterprise field sales targeting large manufacturers, commercial property operators, mining firms, hospitality groups, and transportation companies; a SUN Partner referral program; and joint-venture channels via PT Surya Nippon Nusantara (SNN, a Sojitz Corporation affiliate) for retail real estate deployments such as Aeon Mall BSD City. Notable enterprise clients include Indocement (71.9 MW), Tjiwi Kimia (9.8 MWp), Berau Coal, Bluebird, Padma Hotels, Charoen Pokphand Indonesia, and Aeon Mall. Recognized as Best C&I Service Provider in Southeast Asia (2022) and Best Solar Energy Company by CNBC Indonesia (2024), the company holds ISO 9001, 14001, and 45001 certifications and operates within the broader SUN Group ecosystem alongside sister brands SUNterra (residential/small commercial solar), SUN Mobility (EV charging), and the SUN Foundation (CSR/education).

Revenue model

1. Solar PV System Development & Installation (SUN Purchase): SUN Energy designs, procures, installs, and commissions solar PV systems for industrial and commercial customers. Customers take full ownership of the system from the outset. Revenue is generated as a one-time project fee covering system components, engineering, installation, and permitting. The company also earns from ongoing operations and maintenance (O&M) services under separate agreements.
2. SUN Rental (Solar System Rental): A 15-25 year rental model where SUN Energy retains system ownership and the customer pays a monthly rental fee. Maintenance and repairs are included at no additional cost during the contract period. This provides zero CAPEX access for customers while generating predictable recurring revenue for SUN Energy over a long contract horizon.
3. SUN Leasing (Solar System Financing): A 3-6 year financing/lease model where the customer makes monthly payments and obtains ownership at the end of the contract term. Maintenance is included during the lease period. This bridges the gap between full ownership (SUN Purchase) and rental, generating recurring revenue with a defined end-of-term transfer of asset.
4. Operations & Maintenance (O&M) Services: Ongoing maintenance services including quarterly component checks (panels, inverters, distribution panels), bi-annual panel cleaning, and diagnostic tests on request. Provided as a bundled component of rental/lease contracts at no additional charge, or as a pay-per-request service for purchase-model customers.
