How much does a 5 kW solar system cost in Bangalore in 2025?
Switching to solar is one of the most empowering choices a homeowner can make — but it often begins with one simple question: "What will it actually cost?"
At Arkahub, we understand that numbers can feel confusing, especially when every quote looks different. So here's a clear, no-nonsense breakdown, written to help you make sense of what you're really paying for — and where you can save.
TL;DR:
In 2025, a typical on-grid 5 kW rooftop solar system in Bangalore (without battery backup) generally costs between ₹1.9 lakh – ₹3.5 lakh.
If you opt for a battery or premium-grade equipment, the total can rise to ₹3.5 lakh – ₹5.5 lakh.
Your final price depends on your panel and inverter brand, your roof's design, and whether you'd like night-time backup. To know exactly what works best for your home, simply request a free site visit — our engineers will guide you through everything.
Quick overview: what is included in the price
A standard 5 kW rooftop quote generally covers everything you need for a working solar system:
- ⚡Solar panels: the largest single component cost.
- 🔌Inverter: converts the DC power from your panels into usable household AC.
- 🏗️Mounting structure, wiring & Balance-of-System (BOS) items.
- 👷Labour, testing & commissioning.
- 📋Assistance with paperwork for net-metering and approvals.
(Batteries are priced separately; adding one can significantly increase your total cost.)
At Arkahub, we make sure you understand exactly what's in your quote — so there are no hidden costs, no confusing fine print, and no surprises later.
Local price ranges you can expect (Bangalore, 2025)
Solar pricing can vary because not all systems — or roofs — are the same. Here's what the 2025 market in Bangalore typically looks like:
💰Lower / Budget Bundle
Basic panels, standard inverter, no battery: ₹1.9 – ₹2.9 lakh
💎Mid-Range (Most Common)
Good brand panels, reliable inverter: ₹2.8 – ₹3.5 lakh
⭐Premium / Hybrid System
High-efficiency panels + hybrid inverter ± small battery: ₹3.5 – ₹5.5+ lakh (depending on battery size)
💡Pro Tip: Always ask vendors for a line-item quote listing the panel brand & wattage, inverter model, warranties, mounting type, labour, and taxes. It's the easiest way to compare apples-to-apples — and avoid being swayed by "too-good-to-be-true" totals.
Why the cost range is wide — the main drivers
Solar isn't one-size-fits-all — your home, your usage, and your goals all influence the final price.
Here's what typically makes the difference:
- 🔆Panel brand & wattage: Higher-efficiency, longer-warranty panels cost more per watt.
- ⚡Inverter type: Basic on-grid (string) inverters are more affordable; hybrid (battery-ready) models add flexibility — and cost.
- 🏠Roof complexity & access: Sloped, shaded, or tiled roofs may need customized mounting.
- 🔋Battery inclusion: Adding a 5–10 kWh battery can significantly raise costs.
- 📋Local policy & approvals: How efficiently BESCOM approvals and net-metering are handled can influence the soft costs and project timeline.
At Arkahub, we look at these details upfront so you're not surprised later — we help you choose smart, cost-effective combinations that deliver the best value over time.
How much energy will a 5 kW system produce in Bangalore?
Bangalore is blessed with consistent sunlight, making it one of India's most solar-friendly cities. On average, a 5 kW rooftop system can produce about 6,500 – 7,200 units per year.
Here's a simple estimate:
5 kW × 5 peak-sun hours/day × 365 days × 0.75 (system efficiency)
≈ 6,844 kWh/year
That's enough to offset a significant portion of a typical household's daytime power usage — and drastically reduce your monthly BESCOM bill.
Batteries: additional cost & rough sizing
If you'd like your solar to power night-time loads or provide backup during outages, you'll need batteries.
In 2025, residential battery prices in India generally range between ₹18,000 – ₹30,000 per kWh depending on technology and capacity.
So, a small 5 kWh backup battery (enough for essentials like lights, fans, and a refrigerator) may add ₹90,000 – ₹1.5 lakh, while larger packs for full-home backup can cost proportionally more.
💡Practical tip: If your main goal is reducing daytime bills, skip the battery initially — you can always add one later when your needs grow or prices drop. Arkahub systems are designed with that flexibility in mind.
Net-metering, approvals & Karnataka policy (short)
Karnataka has made rooftop solar adoption smoother in recent years. BESCOM's updated framework (2024–2025) offers quicker approvals and simpler metering options.
Still, the paperwork and procedures can feel bureaucratic — which is why Arkahub handles it for you. From submitting applications to coordinating inspections, we make sure your project moves from "applied" to "approved" without you having to lift a finger.
How to get a reliable, comparable quote – vendor checklist
Before you sign anything, ensure your installer provides the following in writing:
- —Panel make & model (wattage & efficiency)
- —Inverter brand & warranty period
- —Mounting system details & corrosion protection
- —Line-item costs (panels, inverter, BOS, labour, GST etc.)
- —Estimated annual generation (kWh/year) for your roof
- —Net-metering support (will they handle BESCOM paperwork?)
- —Product & performance warranty terms
When you work with Arkahub, you'll receive a transparent, line-by-line quote and a patient explanation of what everything means — so you can make confident, informed decisions.
Quick checklist for homeowners (what to do next)
Request 3 local quotes – and ask for line-item details.
Schedule an on-roof site visit – orientation and shade matter.
Decide on batteries later if your goal is daytime savings.
Confirm BESCOM/net-metering support – let the installer manage it.
Check warranties carefully – panels (25 years typical) and inverters (5–12 years).
And remember — you don't have to figure this out alone. Arkahub's experts can help you compare quotes, understand ROI, and choose a system that fits both your roof and your budget.
