10 Top Solar Companies in Singapore [Updated 2026]

Key Takeaways:
Choosing a solar installer in Singapore is a 30-year commitment so the company you pick has to still be around when something needs fixing in 2050. We scored 10 residential installers across 5 weighted criteria, with track record and after-sales service accounting for 60% of the total score. The top 3 are separated by just 5 points; the real differentiator isn't price, it's what's bundled into the warranty and who's backing the company. Six of the ten don't publish pricing at all — use the EMA benchmark of around S$1,660/kWp to sanity-check any quote you receive.

This guide is published by GetSolar. The same scoring methodology was applied identically to every company on this list, including GetSolar. Sources are cited throughout, and the full per-criterion scores are published for every company so you can audit the reasoning yourself.

Choosing a solar installer in Singapore is a 30-year decision, not a one-off purchase. The panels on your roof will stay there for the next couple of decades, so the company you pick has to be around to honour the warranty when that time comes. That single fact determines how you should rank installers, and it is why this list weighs track record and after-sales service far more heavily than the cheapest retail price.

We scored ten residential solar installers across five weighted criteria, scored 1–5 and weighted to a total out of 100. We then rank them 1 to 10 by that total, and publish the full scorecard for each company so you can decide for yourself.

The Top 10 Solar Companies in Singapore at a Glance

Sources: company websites, EMA, and published 2026 installer guides. "Quote-based" means the company does not publish a per-kWp figure; the EMA market range still applies. #6–#8 are tied on total score and ordered by warranty and after-sales strength.

Scoring Methodology

Each company is scored 1–5 on five criteria, then weighted to a total out of 100. We publish the full score for every criterion and the weighted total for each company, so nothing is held back.

The anchor for every pricing judgement is the regulator's own figure. The Energy Market Authority states that a 10 kWp residential rooftop system costs around S$1,660/kWp in Singapore. We treat that as the neutral midpoint. For a fuller breakdown of what that buys, see our 2026 Singapore solar cost guide.

Criterion 2 carries the most weight because it carries the most risk: a warranty is only worth as much as the company standing behind it, and the hardware and after-sales service are what you live with for 25 years. Criterion 3 now also covers accuracy, not just transparency, since an over-stated savings projection is as misleading as an unpublished price.

A company's raw score total doesn't determine its rank — the weighting does, which is why a company scoring consistently across all five criteria can rank below one that excels specifically on Track Record and Warranty.

The Top Tier

#1. GetSolar

GetSolar pioneered the Rent-to-Own solar model in Southeast Asia and is the only installer on this list backed by a global energy major. That backing supports a genuine $0-upfront option (RTO from S$200/mo) alongside outright purchase, plus a fully-managed, end-to-end service. It's the best all-round choice for homeowners wanting a low-risk, hands-off path to solar.

Strengths:

• ENGIE-backed, the only company here with a global energy parent for 25-year stability
• Industry recognition: ENGIE Innovation Trophies (Jurors' Favourite), HolonIQ's 2023 Southeast Asia Climate Tech 50 (the only renewable-energy startup featured), Cleantech Group's 2024 Cleantech 50 to Watch, and SolarQuarter's 2025 Green Finance Excellence Awards; also featured in The Straits Times, CNA and Lianhe Zaobao
• $0-upfront Rent-to-Own from S$200/month (5-year) or S$210/month (10-year); outright purchases start from S$16,000 depending on the system's size
• All-inclusive RTO: daily monitoring, repairs, maintenance and warranties bundled, never an add-on
• 90% performance guarantee, with a payout for any shortfall
• 800+ installations for homes and businesses, plus a regional footprint across Singapore and Malaysia

1,000 customers in Singapore, between homeowners and businesses such as Fragrance Foodstuff, Scanteak, Garden of Remembrance, plus a regional footprint across Singapore and Malaysia.

Considerations:

• Not the cheapest upfront option on the market
• Smaller install base than the longest-running outright-purchase players

Best for: homeowners who want zero upfront and a fully-managed high-quality system.

#2. Rezeca Renewables

Rezeca is the longest-operating private residential solar installer in Singapore, with a track record stretching back to 2009.

Strengths:

• 17-year track record with 1,300+ landed-home installations

• Single in-house team for design, installation, approvals and decades of maintenance
• UOB U-Solar bank financing for a system you own from day one
• Featured on Channel 8 in 2026; founder recognised as EY Entrepreneur of the Year 2024 Singapore

Considerations:

• Outright or bank-financed model means you carry the asset, not a managed RTO
• Pricing from S$1,200/kWp sits mid-to-premium, not budget

Best for: outright buyers who value the longest proven track record and a single in-house team.

Strong Contenders

#3. PMCE Solar

PMCE Solar has built its reputation on service quality, carrying one of the strongest residential review records in the category.

Strengths:

• 1,000+ completed projects since around 2015
• 4.9-star Google rating for responsiveness and workmanship
• 24/7 system monitoring and a dedicated project contact

Considerations:

• Pricing is quote-based, so expect a site visit before figures
• High demand can make scheduling slower

• Roots are in engineering and commercial work, so residential is one strand of a broader business

Best for: buyers who weigh deep local engineering heritage and a long operating history.

Best for Specific Needs

#5. Eigen Energy

Eigen Energy pairs residential installs with a commercial portfolio that includes DBS, IKEA and Shell, a track record few residential-only installers can match.

Strengths:

• 100+ installations, with blue-chip commercial clients including DBS, IKEA, Shell, UWCSEA and Sembcorp
• 25-year power warranty plus a 10-year materials and workmanship warranty
• Free bi-annual preventive maintenance and free repair in the first year
• Featured customer story on CNA

Considerations:

• Per-kWp pricing is quote-based, so expect a site visit first
• Maintenance beyond the first year is confirmed per contract rather than bundled for the full term

Best for: buyers who want an installer with a proven commercial-grade track record.

#6. SolarGy

SolarGy specialises in building-integrated photovoltaics, solar designed into facades, skylights and roof structures rather than bolted on top.

Strengths:

• BIPV and architectural-integration specialism
• 200+ installations on record; one of the longer-established names
• 25-year performance warranty

Considerations:

• Bespoke integrated work typically costs more than a standard retrofit
• Pricing is quote-based
• Low number of customer reviews

Best for: architecturally sensitive properties and new builds with BIPV requirements.

#7. Union Energy

Union Energy brings blue-chip heritage dating to 1977 and a long history of stable clients.

Strengths:

• Nearly five decades of corporate longevity
• Strong corporate stability for a 25-year horizon

Best for: off-grid and certification-sensitive projects.

#9. Sunollo

Sunollo publishes the most competitive headline pricing on this list, at S$1,000–1,200/kWp for a fully installed residential system.

Strengths:

• Competitive published per-kWp pricing if you're looking for a basic and simple system
• SunolloCare coverage programme spanning up to 25 years
• Both Rent-to-Own and outright purchase available, with monitoring and installation included in quotes

Considerations:

• The newest company on this list, founded in 2023, so the shortest operating history
• SunolloCare coverage requires additional costs, which can add up very quickly
• Worth confirming exactly what the coverage programme includes over the full system life

Best for: budget-conscious buyers comparing only on published price.

#10. Energio

Energio is a boutique installer built around transparency and responsiveness, founded by a homeowner who built his own system before installing for others.

Strengths:

• Boutique scale with lifetime customer support and ongoing system monitoring
• Every project endorsed by a licensed PV LEW (Licensed Electrical Worker) for compliance and safety
• Positions itself on transparency and right-sizing systems rather than overselling capacity
• Handles all SP Group and SCDF permits on the homeowner's behalf

Considerations:

• Smaller and newer than the volume leaders, with a lighter public install record
• Per-kWp pricing is quote-based; founding year not publicly stated and should be verified before publish

Best for: buyers who want a hands-on, boutique installer focused on fit over system size.

Head-to-Head: How the Top 10 Compare

Pricing and Financing Comparison

Six of the ten don't publish pricing at all. Where a plan is RTO, the provider owns the system until the term ends, then ownership transfers to you. Bank-financed plans like UOB U-Solar let you own the asset from day one, but note that they do not include extended warranties and maintenance options.

Warranty and After-Sales Comparison

The panel warranty is the manufacturer's; the features that distinguish installers are maintenance inclusion and a performance guarantee, since both depend on the company surviving to honour them. For what ongoing servicing actually costs, see our solar maintenance cost breakdown.

How to Choose the Right Installer for Your Home

Match the company to what you actually need, not to whoever ranks first on a list.

If you want zero upfront cost: Rent-to-Own removes the capital barrier entirely. GetSolar and Sunollo both offer it; compare what's bundled into the monthly fee, because an included maintenance and warranty plan is worth more than a cheaper payment that bills you separately for maintenance and coverage.

If you want to own the system from day one: Outright purchase or a bank-financed plan like UOB U-Solar keeps the asset yours immediately. Rezeca and Eigen Energy both work this way.

If after-sales service is your priority: Look at warranty length and whether maintenance is included for the contract term, not just the first year. The difference between a 1-year defects period and full-term coverage is thousands of dollars over 25 years.

If you're comparing on price: Use the EMA figure of around S$1,660/kWp as your baseline reference. A quote far below it should raise questions about what's been left out; a quote far above it should come with a clear justification.

Frequently Asked Questions

Who is the best solar company in Singapore in 2026?

There is no single best for everyone. For a $0-upfront, fully-managed system, GetSolar leads; for the longest outright-purchase track record, Rezeca leads. The right pick depends on whether you want to own the system or have it managed for you.

How much do solar panels cost in Singapore?

A typical 10 kWp landed-home system costs S$15,000–S$20,000 outright, or around S$1,450–1,950/kWp. The EMA cites roughly S$1,660/kWp as a representative figure.

What is the cheapest solar installer in Singapore?

On published headline pricing, Sunollo lists the lowest per-kWp rate at S$1,000–1,200/kWp for a basic and simple system. The lowest sticker price is not always the lowest lifetime cost once warranty and maintenance terms are factored in.

What is Rent-to-Own solar?

A financing arrangement where the installer owns and maintains the system while you pay a fixed monthly fee, usually lower than your current bill. You can still keep the earnings from exporting excess solar to the main grid. Ownership transfers to you at the end of the term.

Which companies offer $0-upfront solar in Singapore?

GetSolar and Sunollo both offer $0-upfront Rent-to-Own. Several others offer bank-backed $0-upfront loans through UOB's U-Solar programme.

Is Rent-to-Own cheaper than buying outright?

Over the full system life, outright purchase usually costs less in total because you avoid financing costs. Rent-to-Own wins on cash flow, with no large upfront sum and maintenance typically included.

How long is the payback period for solar in Singapore?

For a landed home, around 5–8 years, depending on roof size, consumption and export rates. Higher-consumption homes with larger systems can see 4–5 years.

How much can I save with solar each month?

Singapore landed homeowners typically save S$240–S$775/month depending on roof size, roughly S$240 for a small roof, up to S$775 for a large one.

Do I need a battery?

For most landed homes, no. Singapore's export schemes let the grid act as a virtual battery and earn from selling excess solar energy, so storage is only worth it if outage protection is a genuine priority.

What is the SCT scheme?

The Simplified Credit Treatment lets residential systems export surplus solar to the grid via SP Group and receive credits at roughly the prevailing wholesale rate.

What is the difference between SCT and ECIS?

SCT is the simplified scheme for smaller residential systems; ECIS (Enhanced Central Intermediary Scheme) covers both residential and commercial, including contestable consumers. Most landed homeowners use SCT.

How much do you earn exporting solar to the grid?

Around S$0.20/kWh for surplus exported under SCT as of Q2 2026, credited against your SP Group bill.

Can I install solar on an HDB flat?

Not individually. Only landed property owners control their own roofs. HDB solar is deployed at block level through public procurement.

Can I install solar on a condominium?

Possibly, but it requires MCST approval, and most condos use master-sub metering, so export credits are shared at block level rather than credited to your unit.

How much roof space do I need?

Around 45–55 square metres of unshaded roof for a 10 kWp system, which suits most landed homes.

How long do solar panels last?

25–30 years. Panels degrade slowly, around 0.4% per year, so they keep generating well beyond the warranty period.

What is a performance guarantee?

A commitment that your system will generate at least a set percentage of its rated output. GetSolar guarantees 90% and compensates for any shortfall during the contract.

What is the difference between a performance warranty and a product warranty?

A performance warranty guarantees output levels over time; a product warranty covers the hardware itself against defects. They run for different periods, so confirm both.

Is maintenance included or extra?

It depends on the installer. GetSolar includes full maintenance in every Rent-to-Own plan for the contract term. Many installers cover only a 1–2 year defects period, after which servicing is your responsibility.

How much does solar maintenance cost if it's not included?

Around S$400–S$600/year for annual servicing in Singapore.

What are Tier-1 panels?

A BloombergNEF bankability classification measuring a manufacturer's financial strength. It is a financing signal, not a measure of panel quality or performance.

Does panel brand matter much?

Less than most buyers assume. Most reputable installers fit comparable Tier-1 panels, so warranty terms and installer service usually matter more than the badge.

What inverter should I look for?

A reputable string inverter with monitoring. The inverter is the component most likely to need replacing within 25 years, so warranty terms on it matter. Most common inverter brands in the market now are Sungrow (most well-rounded), Huawei (higher cost premium), and GoodWe.

Do solar panels work in Singapore's climate?

Yes. Singapore receives around 1,580 kWh/m² of solar irradiance a year, among the highest in Southeast Asia, and panels are built for heat and humidity.

Will solar panels damage my roof?

Properly installed, no. Tiled roofs require drilling for mounting, so waterproofing matters; metal standing-seam roofs need no drilling at all. Ask how the installer handles your roof type.

How long does installation take?

The physical install takes around 5 days for a residential home once permits are approved.

Who handles the SP Group and permit paperwork?

A full-service installer manages it for you. Confirm this is included before signing, as some installers leave parts of it to the homeowner.

What government rebates exist for residential solar?

Singapore does not offer cash rebates for private residential solar installation. The financial benefit comes from bill savings and export credits, not government grants.

How do I compare quotes fairly?

Compare on cost per kWp, not total price. A cheaper total may be a smaller system; a larger system has a lower per-kWp cost but a higher total cost.

What does a solar quote include?

A complete quote covers panels, inverter, mounting, installation, permits and monitoring. Watch for quotes that exclude scaffolding or paperwork to look cheaper.

What is the GetSolar performance guarantee?

GetSolar guarantees your system produces at least 90% of its expected output. If it falls short due to issues within their control, they investigate, fix it, and pay you for the shortfall.

Does GetSolar operate outside Singapore?

Yes. GetSolar operates in both Singapore and Malaysia, which is unique amongst the residential installers on this list and reflects its regional Rent-to-Own roots.

How many homes has GetSolar installed?

GetSolar has powered 1,000+ homes and businesses to date.

Who backs GetSolar?

GetSolar was seed-funded by ENGIE, a global energy group, the only company on this list with a global energy major as a parent backer.

What's the catch with very cheap solar quotes?

Usually a shorter warranty, a thinner maintenance package, or a smaller system than you need. Check coverage terms and system size before comparing on price alone.

Can I add a battery later?

Yes, most grid-tied systems can have storage retrofitted. It's often more cost-effective to add it later, only if outage protection becomes a priority.

What happens to my Rent-to-Own system at the end of the term?

Ownership transfers to you. You then own a system that has typically paid for itself through savings, with years of generation left.

Does solar increase my property value?

It does. Buyers in landed districts increasingly value lower running costs and sustainability features, and a paid-off system is an asset the next owner inherits.

How do I get an accurate price for my home?

The only accurate price comes from a site-specific assessment of your roof, orientation, shading and consumption. Satellite estimates are a starting point, not a quote.

What should I check before signing a solar contract?

Confirm the warranty length on both panels and inverter, whether maintenance is included for the full term, the performance guarantee, the total system size in kWp, and who handles permits.

Which installer is best for a 30-year decision?

Weight track record and warranty service most heavily. On those two criteria, GetSolar and Rezeca score highest, one for management and backing, the other for outright-ownership longevity.

Buy from a Company That Will Still Be There in 2056

The cheapest quote means nothing if the company behind it is gone before your warranty expires. This list rewards track record, financial backing and genuine after-sales service over headline price. For a landed homeowner, the right question isn't "who's cheapest this month," it's "who will still pick up the phone when something needs fixing 20 years down the line."

GetSolar's answer is a $0-upfront system, fully managed by us for its entire term, backed by a global energy company and a written 90% performance guarantee. If that's the kind of certainty you're after, the next step takes about a minute.
