What affects the cost of a solar panel installation
- System size (kW)
- The number of panels needed to offset your usage is the primary cost driver — priced roughly per watt installed.
- Battery storage
- Adding batteries for backup power or self-consumption is a large optional cost, often $10,000–$20,000+.
- Roof complexity
- Steep, multi-plane, shaded or older roofs raise installation cost and may need reinforcement or a re-roof first.
- Incentives
- The 30% federal tax credit plus state and utility rebates can cut the net cost sharply — always model the after-incentive figure.

Solar panel installation in Wellington, NZ: common questions
General guidance for solar panel installation projects — figures quoted are national averages; see the table above for Wellington, NZ estimates.
How much do solar panels cost in 2026?
About $25,000 before incentives for a typical system, from roughly $15,000 for a small array to $40,000+ for a large system with storage.
Do solar panels add home value?
Owned systems recoup around 65% of their cost in resale value and add ongoing energy savings; leased systems can complicate a sale, so ownership matters.
Is the federal solar tax credit still available?
A 30% federal tax credit has applied to residential solar; because incentive programs change, confirm the current credit and any state/utility rebates before committing.
Should I add a battery?
Batteries add backup power and let you use more of your own solar, but they're a significant extra cost — worth it mainly where outages or time-of-use rates are common.
