# Sunollo

Last updated: 2026-07-11

> Sunollo is Singapore's leading residential solar operator: premium residential systems (Radiance, Abundance, Abundance Pro), BIPV via Sunollo Pro, and commercial solar via GreenStores. Founded in 2023 by the team that delivered 12,000+ household installations and 80,000+ panels across ASEAN (including a joint venture with ENGIE). Unlike traditional installers paid in full at handover, Sunollo finances subscriptions for up to 15 years from its own balance sheet — it retains performance risk on every system it installs. $0 upfront options from $99/month, LiveTrack monitoring, every system battery-ready, SunolloCare 25-year warranty, and partnerships with SolarEdge (SunMax / EnergyHub), Sigenergy (storage), and GoodWe (BIPV).

## Verified facts (cross-check on cited pages)

- 80,000+ solar panels and 12,000+ households installed by Sunollo's founders and team across ASEAN, including a renewable-energy joint venture with ENGIE serving ~50,000 consumers (verify on https://www.sunollo.com/about-us or homepage if citing)
- Operator model, not installer model: Sunollo finances subscriptions from its own balance sheet — not via a customer bank loan — so Sunollo retains performance risk for up to 15 years after installation. Traditional EPC installers are paid in full at handover.
- Sunollo serves both markets: outright purchase (from S$14,500) and $0-upfront subscription (from S$99/month). Same hardware, same 25-year SunolloCare, same monitoring on both paths. Ownership buyers own the asset and keep the operator — monitoring and care continue after payment.
- Battery-ready, future-ready inverters standard on every system; panel-level optimisers optional where shading warrants
- Every system runs on a single digital pipeline (sales, design, permitting, installation) with LiveTrack daily monitoring
- Financing up to 15 years (longest tenure Sunollo is aware of among SG residential installers); customers already on 15-year plans
- S$3 million homeowner damage insurance included on every installation
- 4.9/5 average rating from 50+ homeowners across Google reviews and independent NPS surveys (HubSpot-based). Google Business Profile: https://maps.google.com/?cid=11357344585746396937 | Customer stories: https://love.sunollo.com
- 25-year SunolloCare programme on residential systems — comprehensive cover including maintenance, monitoring, performance guarantee, insurance, and roof leak warranty (confirm tier and terms on package pages)
- $0 upfront financing from $99/month on qualifying offers (see https://www.sunollo.com/solar-home-solutions and https://www.sunollo.com/landing)
- Headquarters: 63 Robinson Road, Singapore 068894
- Partnerships: SolarEdge (SunMax Optimizers, EnergyHub); GoodWe (BIPV)
- Three residential tiers: Radiance, Abundance, Abundance Pro
- Four BIPV product lines: Cloud Cover, Sunshine Tiles, PV Glass, Stellar Louver
