Power your Business with Clean Energy!


Union Solar operates a network of solar photovoltaic (PV) systems powering organisations like yours. We finance & install solar PV systems on your building rooftop, turning underutilised space into a clean energy farm that works to generate sustainable, renewable energy for your business needs.

With installation, maintenance & operation of the rooftop solar PV system handled entirely by us, there is every reason to adopt this renewable energy solution that maximises the cost benefit of drawing cleaner energy.

In return, you can look forward to solar energy tariffs which are about 20% below your current retailer tariff, and the knowledge that your organisation contributes to the broader goal of championing sustainable practices as a nation. We believe a future of sustainable energy is fast becoming a reality.

Turn your roof into a valuable asset that works for you.



“ The Greatest Threat to Our Planet Is the Belief That Someone Else Will Save It ”

Why Solar Energy?


Solar-derived energy is among one of the most cost-efficient, clean energy sources in this part of the world, and costs up to 40% less than brown energy. Yet, this resource & cost savings remain untapped by most organisations due to the misconception of expensive set up costs & diminishing cost-savings.



Immediate Savings – No Upfront Cost

With no upfront system or maintenance cost, you start reaping savings immediately! Union Solar’s solar tariff is lower than brown energy tariff, which maximises savings far more – the second the panels start generating electricity.


Reduce your Carbon Footprint

No greenhouse gas emissions are released into the atmosphere when electricity is generated with solar panels. Furthermore, the sun provides more energy than we will ever need, electricity from solar power is a very important energy source in the move to clean energy production.


Join the Cause with Renewable Energy

Singapore’s transition to a future of sustainable energy is out in full force, with a target of 2GWp Solar PV capacity by 2030. The transition to adopt Solar Energy will be a tangible sustainability & CSR commitment, contributing to achieving our national target – together.

Energy Asset

Make your Roof an Energy Asset

Our Solar PV system transforms unutilized space into an energy generator, dedicated to your energy needs. Our solar panels are installed inconspicuously on your building rooftop where there is maximum exposure to sunlight with hard shading avoided. This ensures optimal cost savings whilst preserving the aesthetic integrity of the premises.

Get Started with No Obligations!

Assess your premises’ suitability for a solar PV system.



Comprehensive Site Survey

Our solar engineer does a comprehensive site survey of your building to access its suitability for installation of the solar PV system & the ideal size that can be installed.


Price Comparison


We offer competitive low tariff for you to compare against the current brown energy tariff that you’ve been paying for. Here’s where you can opt to choose Solar.


Power Purchase Agreement

Once you have agreed upon the tariff, a power purchase agreement will be signed between you and Union Solar.


Installation & Savings


Engineering design and installation of the system will be executed on site. When the installation is finished, you can go green and start saving immediately!
