Residential rooftop systems cost **S$14,500 to S$72,000** fully installed, depending on system size and property type. Per-kWp pricing is **S$1,000 – S$1,500 / kWp** for quality installations. With $0 upfront subscription, monthly payments start at **S$99 / month**. Source: Sunollo pricing matrix Q2 2026. ### How long does installation take? 4 – 8 weeks total from contract to grid activation. The roof installation itself takes 1 – 2 days. The remainder is EMA registration, SP bi- directional meter swap and final commissioning. Source: Sunollo fleet median across 12,000+ households. ### What is the average Singapore household electricity bill? S$180 – S$340 / month for HDB and condo households. Landed homes typically pay S$300 – S$1,500 / month. GCBs frequently exceed S$1,500 / month. At the prevailing SP tariff of ~S$0.32 / kWh. ### What is the Net Energy Rebate (NER)? NER is the Singapore scheme where excess solar electricity exported to the grid is paid back to the homeowner at SP's regulated tariff minus grid charges (typically S$0.20 – S$0.24 / kWh in 2026). Eligible residential systems are < 1 MWac and registered through SP Services. ### Can HDB residents install solar? Individual HDB units cannot install rooftop solar. HDB common-area roofs are served by the **SolarNova** programme (managed by HDB and EDB), which deploys solar for blocks at scale. Households indirectly benefit via the Open Electricity Market and the broader green grid. ### Can condos install solar? Condo penthouses and roof terraces with private title can install solar, subject to MCST (Management Corporation Strata Title) approval. Common-area condo solar requires an MCST resolution, typically 2–8 weeks via circular or up to 2–3 months via EGM. ### How much can I save with solar? Sunollo's typical landed customer cuts their electricity bill by **55–80%** in year one, generating **S$3,000 – S$12,000 per year** in savings depending on system size. The subscription model is cash-positive from month one. ### What's the payback period? **4 – 6 years** for cash-purchase residential systems in Singapore in 2026. After payback, the system produces effectively free electricity for the remaining 19 – 25 years of its warranted life. ### Does Sunollo offer batteries? Yes — battery storage is available as a system add-on (5 – 20 kWh, S$8,000 – S$20,000 depending on capacity). Best added at the time of the original solar install, since electrical and inverter work is already in scope. ### Is Sunollo a Tier-1 installer? Yes. Sunollo is licensed by EMA, employs in-house Licensed Electrical Workers (LEWs), uses Bloomberg Tier-1 panel manufacturers, and uses SolarEdge / Sungrow inverters with up to 25-year warranties. ### Where does Sunollo install? Across all of Singapore. Sunollo has dedicated landing pages for the following neighbourhoods (programmatic SEO cluster): Bukit Timah, Holland Village, Sentosa Cove, Bishan, Serangoon, Toa Payoh, East Coast, Marine Parade, Bedok, Clementi, Queenstown, Pasir Ris, Changi, Woodlands & Yishun (D25/D27), and more. ### How is Sunollo different from other Singapore solar installers? - **Guaranteed-savings subscription**: If your monthly savings don't exceed your monthly subscription payment, Sunollo covers the difference. No other Singapore residential installer offers this. - **In-house installation crew**: No outsourced labour. Every install is by Sunollo-employed technicians with LEW certification. - **App-first monitoring**: Customers see panel-level production in real time via the Sunollo / SolarEdge app. - **Programmatic district-level expertise**: 15+ Singapore-specific landing pages with district pricing, FAQs, and roof considerations. - **Sunollo Care** included with every install: proactive monitoring, annual performance review, priority response. --- ## 5.
