The 10 Best Solar Panel Installers in Singapore

PMCE Global suits owners who want one installer for both a landed home and a business roof. The company designs personalised systems for houses across Singapore and runs a separate commercial and industrial service, with factory rooftops among its featured projects. It reports more than 1,500 installations. Customers get access to a digital solar assistant and a customer portal, and the site explains how renewable energy certificates and monthly savings work before you commit.

Solar Lab is a good fit for landed homeowners who want the founder involved on their roof. Founded in late 2024, the company works only on residential solar and designs each system around the site rather than a template. Its founder manages installations and works on site with the crew. Before panels go up, it can also repair leaks, waterproof and paint the roof, and install a home EV charger on the same project.

Rezeca Renewables suits buyers who value a long track record and installers on the payroll. It has installed solar in Singapore since 2009 for terrace houses, semi-detached homes and bungalows, as well as warehouses, factories and offices. Systems use Tier 1 panels from Trina, Aiko or Jinko with Huawei, Sungrow or Fronius inverters. A PV Licensed Electrical Worker certifies each system, and a smartphone app shows generation and sends fault alerts.

FOMO Energy suits homeowners who want solar without paying the full cost upfront. Its rent-to-own plan has no upfront payment, and ownership of the system passes to the homeowner at no extra cost after a five to ten-year rental period. Systems use Tier 1 Aiko panels with a 30-year output warranty and a five-year workmanship warranty. Monitoring runs around the clock, and cleaning, inspections and repairs are included.

UTICA Solar stands out for owners whose roof needs replacing or reworking alongside the solar system. It designs, installs and supports systems for Good Class Bungalows, detached, semi-detached, terrace, cluster and conservation houses, and for commercial and industrial sites. Solar, roofing and electrical work are delivered together with its sister companies UTICA Roof and The Electrik Company. Systems come with live monitoring, remote diagnostics and fault alerts.

Solar SG appeals to owners of large homes who care about how the panels look on the roof. It has dedicated services for Good Class Bungalows, ordinary homes and commercial buildings, and offers full black N-type panels as well as regular ones. Panels come from Tier 1 makers such as Jinko, Longi, Aiko and Trina, with a 30-year output warranty and a 25-year product warranty. It also provides a back-to-back rooftop warranty.

9 Helios is a practical choice for owners who already have panels and need them checked, repaired or upgraded. Besides new residential and commercial systems, it offers a dedicated service for inspections, cleaning, repairs and upgrades of solar installations. The team has installed more than 10,000 panels. It also fits EV chargers for homes and businesses, and commercial clients can use flexible financing.

Eigen Energy suits owners who want a feasibility study and a choice of financing before they commit. The company has ten years in business and more than 1,200 clients, with projects ranging from landed homes on Cypress Avenue and Jalan Senir to IKEA Tampines and Marina Barrage. Its services run from design advisory and turnkey integration to operation and maintenance. Several ownership and financing models are available to reduce the upfront cost.

SunPro Energies is a sensible pick for clients who want design, approvals, installation and maintenance kept within one company. The solar EPC firm has more than ten years in the industry and runs an in-house team of solar designers and construction workers. Its designers visit the site first to check shading and the cost benefit before proposing a system. It works on homes, commercial and industrial buildings and government projects, and offers battery storage and monitoring.

Union Energy makes sense for businesses that want solar, electricity supply and EV charging from one provider. Alongside its electricity plans, it installs solar for homes and commercial properties. Commercial clients can choose between a power purchase agreement and a turnkey system they own. The company also installs EV chargers for homes and businesses and runs the Union Charge app for finding public charging points.
