Battery storage prices in Singapore have fallen sharply — and 2026 marks the year home batteries have become genuinely accessible for most landed property owners. Prices have dropped 40–50% since 2023, driven by massive LFP manufacturing scale-up and fierce competition. This guide gives you accurate 2026 pricing across all battery sizes and brands, including Sunollo's own purpose-built options for Singapore homes.
Sunollo Battery Range — 2026 Singapore Prices
Sunollo offers two battery products engineered specifically for Singapore's climate and electricity market. Both use LFP (Lithium Iron Phosphate) chemistry, integrate with the Sunollo EnergyHub inverter, and are monitored via the LiveTrack app:
| Product | Capacity | Installed Price | Cost per kWh | Best For | Warranty |
|---|---|---|---|---|---|
| Sunollo Essential | 9 kWh | SGD 6,000 | SGD 667/kWh | Terrace houses, moderate users, first-time battery | 10 years |
| Sunollo Abundance | 18 kWh | SGD 12,000 | SGD 667/kWh | Semi-D, bungalows, EV owners, high consumption | 10 years |
Both are available standalone or included in the Abundance Pro subscription (SGD 0 upfront, from SGD 129/month). See our payback period analysis for full ROI calculations at these prices — both batteries pay back in approximately 8 years without an EV, and 5–6 years with one.

What Drives Battery Cost
Battery Chemistry
LFP (Lithium Iron Phosphate) is now the overwhelmingly dominant chemistry for residential storage in Singapore. It is 25–35% cheaper per kWh than NMC alternatives, offers 6,000+ cycle life versus 3,000 for NMC, and is significantly safer in Singapore's tropical heat. All Sunollo batteries use LFP. Read our battery comparison guide for a full chemistry and brand breakdown.
Capacity Sizing
The right battery size matches your evening and overnight consumption — the hours when solar panels produce nothing. A typical Singapore landed home consumes 15–25 kWh per day, with 8–15 kWh occurring after sunset. The Sunollo Essential (9 kWh) covers most evening needs for a terrace house; the Sunollo Abundance (18 kWh) covers all evening needs plus overnight EV charging for a semi-D or larger home. Explore our battery planning guide for a step-by-step sizing methodology.
Oversizing is wasteful — a battery that cycles at 30–40% capacity daily never delivers full ROI. Undersizing means continued evening grid dependence. Sunollo sizes every installation to your actual consumption data.
New Installation vs Retrofit
Installing battery at the same time as solar is 10–20% more cost-efficient than retrofitting later. New installations benefit from shared inverter infrastructure, single-visit labour costs, and integrated wiring design. Retrofitting an existing system may require inverter upgrades, new cable runs, or switchboard modifications — adding SGD 1,000–3,000. All prices quoted for Sunollo Essential and Abundance assume new installation.
Brand Premium
Tesla Powerwall carries a significant brand premium — SGD 13,000–18,000 for 13.5 kWh versus SGD 6,000 for a comparable LFP battery. The extra cost reflects Tesla's ecosystem and monitoring UI, not superior chemistry or longer lifespan. For most Singapore homeowners, choosing a right-sized Sunollo battery and investing the difference in more solar panels or an EV charger delivers far better overall returns.
Cost Per kWh: The Real Comparison Metric
Total system price is a misleading comparison. The metric that matters is cost per usable kWh of storage over the battery's lifetime. In 2026 Singapore:
| Tier | Cost per kWh (installed) | Example Products |
|---|---|---|
| Budget LFP | SGD 500–700/kWh | Huawei LUNA2000, BYD smaller modules |
| Sunollo (Essential & Abundance) | SGD 667/kWh | Sunollo Essential 9 kWh, Sunollo Abundance 18 kWh |
| Mid-range LFP | SGD 700–900/kWh | BYD Battery-Box Premium, Sigenergy, GoodWe Lynx |
| Premium LFP | SGD 900–1,200/kWh | Enphase IQ Battery, Tesla Powerwall 3 |
Factor in cycle life when comparing: a battery at SGD 667/kWh lasting 6,000 cycles (Sunollo LFP) delivers a lifetime cost of SGD 0.11 per kWh cycled — less than a third of Singapore's retail electricity rate. This is the true economics of battery storage: every kWh you store and self-consume returns roughly 3× its storage cost in electricity savings.
$0 Upfront: The Sunollo Subscription Option
Sunollo's Abundance Pro subscription eliminates the upfront cost entirely. For SGD 0 down and from SGD 129/month, you receive panels, a battery (Essential or Abundance, sized to your home), EV charging capability, monitoring, full warranty coverage, and battery replacement if needed during the term. Your monthly subscription is typically less than your current electricity bill — making the financial case immediate.
This model removes the payback question entirely: no capital at risk, no 8-year wait, no technology risk. Sunollo carries all of it. See our complete battery guide for a full subscription vs purchase comparison.
Will Battery Prices Keep Falling?
Yes — but the case for waiting is weaker than it appears. Battery costs are projected to fall a further 15–25% by 2028 as LFP manufacturing continues scaling and sodium-ion batteries begin entering the residential market. However:
- Every month without storage is a month exporting solar at SGD 0.10/kWh instead of self-consuming it at SGD 0.32/kWh — a SGD 0.22/kWh daily opportunity cost
- Singapore's electricity tariff is rising every quarter — waiting for cheaper batteries while paying higher bills is a losing trade for most households
- A 20% price drop on SGD 6,000 saves SGD 1,200 — but 12 months of foregone battery savings at ~SGD 60/month has already cost SGD 720 in lost savings
- Under Sunollo's subscription model, you capture today's savings immediately with Sunollo carrying all technology improvement risk
The optimal strategy: install a right-sized battery now and lock in today's savings immediately. See our full guide to solar battery storage for complete sizing guidance and brand-by-brand comparisons.
