District 22, covering Boon Lay, Jurong and Tuas, is Singapore's western industrial heartland, where large factory and warehouse roofs are ideal for commercial and industrial solar at scale. Rezeca Renewables has delivered large rooftop systems across Jurong and Tuas since 2009, from a few hundred kWp to over a megawatt. Commercial rooftop solar here typically costs S$600 to S$1,200 per kWp, with fast payback driven by high daytime consumption.
Every roof is scoped individually to the building, its structure and its load. At the 2026 SP tariff of about 34.78 cents per kWh including GST, offsetting daytime consumption typically delivers the bulk of the saving, with excess exported for a credit.

We installed a 400.40 kWp system on a factory on Tuas Avenue, saving in the region of S$160,000 a year, and a 257.40 kWp system on a warehouse on Tuas South Street, saving about S$103,000 a year, alongside projects at Kian Teck Way and Pandan Crescent. Our engineering-led EPC team manages design, structural checks, installation and connection.
Large metal roofs suit high-density arrays, but structure, roof condition and safe access all matter. We assess load capacity and use mounting matched to the roof, with minimal disruption to operations.
We scope the roof, design the system and handle approvals and connection, then install with minimal disruption and set up monitoring. Contact us to scope a commercial installation for your District 22 building.
The installations shown here are a small selection that we were able to photograph and feature with our customers' consent. Rezeca Renewables has completed many more projects in this area and across Singapore since 2009.
