How Companies Go Solar in Singapore: The Full Process

Key Takeaways:
Going solar as a business in Singapore follows five stages: enquiry, site assessment, proposal, installation, and post-installation support. Most projects stall at the very first step, when providers take too long  just to respond. GetSolar's Solar Calculator and virtual SDRs cut that wait to minutes, and support continues well after your system goes live.

If you've been exploring solar for your business in Singapore, you've probably filled out a form, sent an email, or made a call and then waited. That wait, more than anything else, is where most commercial solar projects lose momentum before they even start.

This is our guide on how companies in Singapore go solar, and how we make a project smooth, fast, and worth doing.

Step 1: Reaching Out

Where most companies already lose momentum

For many businesses, the solar process starts with either:

• Filling up a website form
• Sending an email enquiry
• Calling the provider for a rough estimate

Simple enough. Except this is where many projects already slow down.

Response times vary a lot across providers with some moving quickly, while others take days or even weeks just to arrange a site visit. Either way, the internal momentum a business had when it first reached out can disappear before a single real number gets discussed.

At GetSolar, we put a lot of emphasis on speed, because we know businesses don't want to wait around for basic answers. Check out our Solar Calculator and within minutes, you'll get a personalised estimate of your potential savings based on your building and energy usage.

Once you use it, our virtual SDRs (Sales Development Representatives) get back to you immediately to answer questions and get the ball rolling. These virtual assistants work round the clock, so even if you reach out at midnight, you're not waiting until the next business day for a response.

Step 2: Site Assessment

"Can this roof even support solar?"

Once a company is interested, the next step is usually a site visit. This is where the solar provider assesses:

• Roof size and condition
• Electrical infrastructure
• Available sunlight exposure
• Energy consumption patterns
• Potential system size
• Safety and installation constraints

A good solar company doesn't just try to fit as many panels as possible. They advise how solar can best make financial and operational sense for your building.

After using our Solar Calculator, our sales team follows up with you directly. We then run a virtual roof assessment using satellite imagery, so you get a preliminary read on whether your building is a good fit. If it is, we move quickly to arrange a physical site visit and walk you through an initial proposal on the spot.

Step 3: Proposal and ROI Analysis

The part everyone cares about

After the site visit, you'll typically receive:

• Estimated system size
• Projected energy generation
• Electricity savings
• Payback period
• Carbon reduction estimates
• Installation timeline

This is also where many businesses start comparing vendors. Most proposals look similar on paper. The real difference usually comes down to:

• Cost
• Responsiveness
• Transparency
• Long-term support
• Execution capability
• Financing options (RTO, PPA, or direct purchase)

GetSolar keeps the proposal stage straightforward. We walk you through the figures, explain what they mean for your building, and give you a clear picture so you can decide with confidence.

Step 4: Installation

The exciting part

Once equipment arrives and logistics are coordinated, installation begins alongside the necessary approvals. A commercial solar installation in Singapore can take anywhere from a few weeks to several months, depending on:

• Roof complexity
• System size
• Electrical works required
• Operational constraints

A good installer minimises disruption to your operations while coordinating:

• Safety requirements
• Electrical integration
• Testing and commissioning

At GetSolar, every installation is coordinated around your operations, not the other way around. For one of our recent projects at Gul Street 2, our client ran an active manufacturing facility with forklift traffic and only a single entry point. We scheduled heavy hoisting over weekends to avoid disrupting the factory floor, and when the original inverter placement posed a safety risk, we redesigned the layout on-site rather than push ahead with a plan that didn't work. The full installation was completed in three months from contract signing.

Every site is different. But the approach stays the same: move fast, stay safe, and keep your business running while we power your operations with the sun.

Step 5: Post-Installation Support

The most overlooked part of going solar

This is where many solar companies disappear too early. For us, installation isn't the conclusion of our business model.

At GetSolar, we continue supporting clients after installation, because going solar is rarely just about electricity savings. It's also a sustainability milestone that touches:

• Corporate sustainability
• Brand positioning
• ESG reporting
• Future-proofing your business

In practice, this looks like:

• Featuring your project post-installation
• Highlighting your carbon reduction efforts
• Supporting your ESG messaging
• Providing energy and savings reports

If your company invests in sustainability, that deserves to be highlighted. Solar is a long-term investment that should last 20+ years, and you want a partner who still picks up the phone after installation is complete. That's us.

So, How Do Companies Successfully Go Solar in Singapore?

The smoothest projects happen when companies choose a solar partner that:

• Responds quickly
• Explains things clearly
• Moves fast operationally
• Doesn't disappear after installation
• Understands both the technical and business side of solar

Panels matter. Engineering matters. Pricing matters. But execution matters just as much.

After working with several businesses across Singapore, we believe the solar experience should feel simple, responsive, and collaborative from start to finish. Many of our clients have shared their experience through a Google review.

That's the standard we're building at GetSolar.

Frequently Asked Questions

How long does commercial solar installation take in Singapore?

Anywhere from a few weeks to several months, depending on roof complexity, system size, and electrical works required. For one recent GetSolar project at Gul Street 2, an active manufacturing facility with tight site constraints, the full installation was completed in three months from contract signing.

How fast do solar companies respond to enquiries in Singapore?

Response times vary widely across providers. GetSolar's virtual SDRs respond within minutes of you using the Solar Calculator, 24 hours a day.

What happens during a commercial solar site assessment?

A provider evaluates your roof size and condition, electrical infrastructure, sunlight exposure, energy consumption patterns, potential system size, and safety or installation constraints. GetSolar starts with a virtual assessment using satellite imagery before confirming details with a physical site visit.

What financing options are available for solar in Singapore?

Businesses typically choose between Rent-to-Own (RTO), a Power Purchase Agreement (PPA), or direct purchase. GetSolar's Rent-to-Own model requires zero upfront cost, with savings starting from day one.

Does support end once the solar system is installed?

It shouldn't, but with some providers it does. GetSolar continues supporting clients after installation with performance monitoring, savings reports, and help with ESG and sustainability messaging, backed by a written 90% production performance guarantee in Singapore.

What should I look for when comparing solar companies in Singapore?

Look past the quote and check responsiveness, transparency, execution track record, and what happens after installation. Most proposals look similar on paper; the real difference shows up in how the provider performs on site and how they handle you afterward.
