How to Choose a Solar Installer in Singapore (2026): An Honest Comparison

How to choose a solar installer in Singapore

Search "best solar installer Singapore" and you will find dozens of "top 10" lists, most published by the companies ranking themselves first. This guide takes a different approach: an honest comparison of Singapore's leading solar installers on objective, verifiable criteria, so you can decide which is right for your home and budget.

We are transparent that this guide is published by Rezeca Renewables. We believe our 17-year track record and 1,300+ landed-home installations make us the strongest choice for homeowners who want to own their system outright. But no single installer is right for everyone, and we have been honest about where competitors genuinely excel, particularly on financing and zero-upfront options.

The criteria that actually matter

A solar system is a 25 to 30 year decision. The hardware is largely commoditised, as most reputable installers use the same Tier-1 panels and inverters. What separates them is longer-term: track record, ownership model, financing, and who will still be around to honour your warranty in year 20. We compared installers on six criteria:

• Years in operation, a proven track record under Singapore's tropical conditions.
• Installations completed, the verifiable scale of work, especially on landed homes.
• Ownership model, whether you own the system outright or rent it through a monthly plan.
• Financing options, upfront purchase, bank financing, or rent-to-own.
• Pricing transparency, whether they publish clear pricing or require an enquiry.
• Independent recognition, media coverage, awards, and certifications.

The installers in detail

Rezeca Renewables, best for outright ownership and proven track record

Operating since 2009, Rezeca is the longest-established private solar installer in Singapore focused on the landed-home and commercial segments. With 1,300+ residential installations across terrace houses, semi-detached homes, bungalows, and Good Class Bungalows, and over 1,500 projects in total, Rezeca has the deepest landed-home track record of any installer in this comparison.

Rezeca was featured by national broadcaster Channel 8 (8world) in a 2026 segment on residential solar, and its founder was recognised as EY Entrepreneur of the Year 2024 Singapore. The company installs only Tier-1 equipment, uses an in-house team with no subcontractors, and handles all SP Group, EMA, BCA, and URA submissions. Every engagement begins with a free on-site assessment, so the proposal reflects your actual roof, orientation, shading, and consumption rather than a satellite estimate. Landed-home systems start from approximately S$1,200 per kWp, with a 30-year panel warranty as standard.

For homeowners who prefer to finance rather than pay upfront, Rezeca is a partner under UOB's U-Solar programme, which provides bank-backed financing for a system you own from day one. This is a different model from rent-to-own: you hold the asset and capture the savings, while spreading the cost through a bank facility.

Best for: homeowners who want to own their system outright, value a proven 17-year track record, and want a single in-house team handling design, installation, approvals, and decades of maintenance.

GetSolar, best for $0 upfront with no commitment

Founded in 2020 and backed by global energy group ENGIE, GetSolar pioneered the rent-to-own (RTO) solar model in Singapore, offering systems with $0 upfront cost and a fixed monthly fee. The company reports 3,200+ homeowners and businesses served. Its strength is removing the upfront capital barrier, so homeowners start saving from day one without a large initial outlay, with a 90% performance guarantee until ownership transfers.

Best for: homeowners who want solar without upfront capital and are comfortable with a monthly payment model. Note that under rent-to-own, you do not own the system until the contract term completes. See the financing section below for how this compares to financing a system you own.

Sunollo, best for low monthly entry cost

A newer entrant (founded 2023), Sunollo has scaled quickly with financing plans starting from $99 per month and reports 80,000+ panels installed across 12,000+ households. Systems carry a 25-year warranty. Sunollo competes on accessible monthly pricing and has a strong content marketing presence.

Best for: homeowners prioritising the lowest monthly entry point. As with all financing models, calculate the total cost over the full term versus an outright purchase to compare true value.

SolarGy, best for architectural integration

One of Singapore's longer-established installers, SolarGy specialises in building-integrated photovoltaics (BIPV), solar designed into facades, skylights, and roof structures rather than retrofitted on top. A natural choice for architects and premium new-builds where aesthetics matter as much as energy yield.

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

1st Solution Group, turnkey mid-market

A credible mid-tier installer offering turnkey solar across HDB, landed, commercial, and industrial properties, with 200+ installations on record. Publishes pricing in the S$1,450 to S$1,950 per kWp range and offers a 25-year performance guarantee.

Best for: homeowners wanting fixed turnkey pricing from a mid-market provider.

Sembcorp and EDPR Sunseap, utility-scale and commercial

These are Singapore's largest solar players by installed capacity, dominating the public-sector SolarNova programme (HDB, schools, government buildings) and large commercial projects. They offer Power Purchase Agreement (PPA) financing for large rooftops but are less focused on individual landed homes.

Best for: large commercial and industrial rooftops, and PPA financing at scale.

Owning versus renting: how to compare financing honestly

This is where many homeowners get caught out, so it is worth understanding the maths. Solar payback in Singapore is now typically 3 to 6 years, meaning the system pays for itself in savings within that window and then generates largely free electricity for the remaining 20+ years of its life.

Rent-to-own and long monthly-financing plans usually run 5 to 10 years. The question to ask is straightforward: during those early years when the system is paying for itself, who keeps the savings? Under a rent-to-own arrangement, the provider owns the system through the contract term, so a significant share of the early financial benefit, exactly when payback happens, accrues to the provider rather than to you. You typically take full ownership only after the term ends.

This does not make rent-to-own a poor choice for everyone. For a homeowner who cannot or prefers not to commit capital, and who values having maintenance bundled in, it is a legitimate and convenient option. But it is not the only way to avoid a large upfront payment. Bank-backed financing, such as UOB's U-Solar programme, lets you finance a system you own from day one, so you hold the asset and capture the savings during the payback years while still spreading the cost.

Before deciding, ask any financing provider for the total amount payable over the full term, then compare it against the outright purchase price plus the savings you would keep. Run the numbers over the full 25-year life, not just the monthly headline.

Which installer is right for you?

• If you want to own your system outright and value the longest proven track record, Rezeca Renewables (since 2009, 1,300+ landed installs).
• If you want to finance an owned system rather than pay upfront, ask about bank-backed options such as UOB U-Solar through an established installer.
• If you want $0 upfront with maintenance bundled and no large commitment, GetSolar's rent-to-own or Sunollo's monthly plans, having compared total cost over the full term.
• If aesthetics and architectural integration matter, SolarGy's BIPV.
• If you run a factory, warehouse, or large commercial building, Sembcorp or EDPR Sunseap with PPA financing.
• If you live in an HDB flat or condominium, most private installers (including Rezeca) do not serve these; HDB is covered by the SolarNova programme, and condos require MCST approval.

Questions to ask any installer before signing

• How many years have you operated in Singapore, and how many landed-home installations specifically?
• Do I own the system outright, or is this a rental or financing model? If financing, what is the total cost over the full term, and when do I take ownership?
• Are your installers in-house, or do you subcontract?
• Which Licensed Electrical Worker (LEW) will sign off on my system?
• What is the panel and workmanship warranty, and who honours it if you cease operating?
• Can you show me 3 reference installations of similar size to mine?
• Will you handle all SP Group, EMA, BCA, and URA submissions?
• Will you conduct a free on-site assessment, and provide an itemised quote with a 25 to 30 year ROI projection based on my actual roof and consumption?

The bottom line

Singapore's solar market in 2026 is genuinely competitive, and homeowners are the beneficiaries. There are more ways than ever to go solar, whether by paying upfront, financing a system you own, or renting through a monthly plan.

For homeowners who want to own their system outright and want the confidence of the longest proven track record, Rezeca Renewables stands apart: operating since 2009, with 1,300+ landed-home installations, featured on Channel 8 in 2026, and recognised through EY Entrepreneur of the Year 2024. Every engagement starts with a free on-site assessment, the system is yours from day one, and for those who prefer to finance, bank-backed UOB U-Solar options keep the asset, and the savings, in your hands. When an installer needs to support your system through year 25, honouring warranties, replacing inverters, and managing performance, longevity and depth of experience matter most.

Whichever route you choose, use the questions above, ask for references, and compare total lifetime cost rather than just the upfront or monthly figure.
