What Determines Your Solar Installation Cost?
Five factors drive the final solar panel installation cost for your home:
- 1System size — Larger systems have higher absolute cost but lower cost-per-kW. Most cost-efficient system size for Indian homes is 3–5 kW.
- 2Panel brand and efficiency — Tier-1 monocrystalline PERC panels (30-year performance warranty) cost more upfront but deliver more power per square metre over 30 years. Arkahub uses only Tier-1 panels.
- 3Inverter type — String inverters are standard and cost-effective. Microinverters allow panel-level monitoring and perform better under partial shading but at higher cost.
- 4Mounting structure — ArkaCore (floor-mounted) is most affordable. ArkaSky (elevated) and ArkaScape (gazebo) add to structure cost but create additional usable roof space.
- 5Roof complexity — Flat terraces with open space have the lowest installation labour cost. Sloped or multi-orientation roofs require more engineering work.
“We are extremely happy about choosing Arkahub. The cost was competitive and they delivered on every promise and handled the entire process seamlessly.”
