Transnational Uyeno Solar Corporation (TUSC) is engaged in solar power generation and systems integration. Its mission is to provide clean power and build a sustainable, clean and green world by promoting the widespread adoption of solar energy.

With a diverse portfolio of solar installations in the country, TUSC is one of the leading solar energy companies in the country. TUSC has distinguished itself as one of the pioneers in solar power generation in the country, building the first-ever solar photovoltaic (PV) carpark in the country without any government subsidies. This milestone project has given the company firsthand experience in the development, construction, operations and maintenance of a solar PV plant, and has provided critical information on the performance of different solar technologies.

TUSC is a joint venture between two strong, stable and forward-thinking organizations: Philippine-based Transnational Renewable Energy Corporation (TREC), and Japan-based Uyeno Green Solutions Ltd. (UGS).

TREC is a proud member of the Transnational Diversified Group of Companies, a strong Philippine-based business group of more than 30 dynamic member companies that are major players in diverse industries such as shipping, logistics, ship management, education, air and travel, business process outsourcing, information and communications technology, and others. A fully owned subsidiary of TDG, TREC is engaged in the research, exploration, generation, development and production of renewable energy, with investments in various wind and solar energy projects in the country.

The Uyeno Group is Japan’s second largest domestic petroleum logistics company and the only company that offers end-to-end solutions for the petrochemical industry. UGS provides logistics and distribution services for solar panels and is a certified solar systems integrator with a large portfolio of solar installations and megasolar investments in Japan.

Why Choose TUSC

Over the years, Transnational Uyeno Solar Corporation (TUSC) has evolved to become among the country's most reputable solar energy companies, consistently commiting to providing clean power and building a sustainable, clean and green world. Built on hands-on experience and high quality service, TUSC has since distinguished itself as having built The country's first-ever solar photovoltaic (PV) carpark -- currently the third largest solar installation in the country. The 206.5 kWp car park, located in Canlubang, Calamba City has given TUSC the first-hand experience in constructing, installing, operating and maintaining a solar PV plant, due to the management expertise, skills and qualifications of its people to meet the ever-changing needs of its clients.

TUSC is commited to building trust among its clients; as such, its people are dedicated to providing service of the highest quality. TUSC's value proposition is built on:

Track Record & Capability

TUSC has installed and commissioned both large- and small-scale solar PV systems in a timely manner and compliant with the safety, design and aesthetic parameters of its clients.

Cost Performance

TUSC ensures that it utilizes high-quality components and partnesr with top tier contractors and suppliers at cost competitive prices to maintain long-term performance of its installations.

Project Life Cycle Management

TUSC supports clients from due diligence until post-commissioning to ensure that the systems are optimally designed and are operating as expected.



Power Generation

In September 2011, TUSC installed a 206.5 kWp solar carpark and solar panel test bed that utilizes four different types of solar panels to compare the yields and efficiencies of various technologies.

The solar carpark has an annual output of 300,000 kWh of clean energy, equivalent to more than 220,000 kg of avoided carbon emissions. It is currently the third largest solar PV installation in the entire country and the first-ever solar parking canopy.

TUSC is also set to develop large-scale solar PV plants in the country, Japan and other Southeast Asian countries, for which the company is currently undertaking technical and feasibility studies, acquiring the necessary government permits and financing arrangements.

Systems Integration

In addition to power generation, TUSC provides technical design, procurement and installation of solar PV systems for third party owners. Such systems can be located in urban areas (grid-tied) where solar power displaces more expensive and price-volatile grid power, and in remote areas such as islands where solar power displaces highly expensive power sourced from diesel generators and provides numerous environmental and health benefits such as zero carbon footprint, zero pollution and zero noise.

TUSC has successfully installed and commissioned a several grid-tied solar systems including a 100 kWp solar rooftop installation in a manufacturing facility, a 65 kWp solar rooftop system in a university, a 20.5 kWp solar rooftop installation in a commercial destablishment, and a 10.78 kWp residential solar rooftop system. TUSC has also commissioned the first-ever purely renewable charging station for e-vehicles in the country, a 14 kWp battery-backed solar charging station in Boracay Island.


Benefits of Solar

  1. Lowers and stabilizes electricity costs
    • Displaces expensive power sourced from the grid and from diesel gensets
    • Cost is fixed over the life cycle of the installation (25 years)
  2. Flexible and modular, fast to install
    • System can be sized and configured according to owner’s needs and specifications
    • Design can be easily adapted to the desired look
    • Installation can be done in as fast as a month
  3. No geographical limitations and raw material vulnerabilities
    • Sunlight is free and unlimited!
  4. Provides zero carbon footprint, zero pollution, zero noise, and consistent with the sustainability goals of eco-conscious companies
  5. Provides “cooling effect” on buildings which may lead to electricity cost savings (i.e. on air-conditioning use)
    • Solar panels shade the roof of the building and can reduce the temperature inside the building by up to 5 degrees Celsius
    • This may lead to a significant reduction in the use of air-conditioning or the load of the air-condition thereby indirectly reducing electricity cost



TUSC’s roster of projects includes:

With its highly competent team and strong belief in clean energy, TUSC hopes to further promote the widespread adoption of solar power in the country and ensure that the next generations can benefit from the clean, sustainable world that renewable energy can bring.
