Solar panels for a bungalow typically cost $10,300-$28,000 before incentives in 2026 for a 4-8 kW system, or about $2.57-$3.50 per watt installed. The 30% federal homeowner tax credit (Section 25D) ended on December 31, 2025, so a system you buy with cash or a loan and place in service in 2026 earns no federal credit. At the U.S. average residential rate of 18.31 cents per kWh (EIA, July 2026), simple payback runs roughly 11-15 years.
Three variables drive your actual number: your roof’s usable area and sun exposure (which set how much a system produces), your local electricity rate (which sets what each kWh is worth), and your utility’s net metering or net billing rules (which set what exported power earns). This guide uses one transparent model so you can swap in your own inputs.
Bungalows are single-story homes with a wide, low roof, which often leaves generous roof area but can mean more shading from trees and neighboring structures. This guide models a 1,400 sq ft bungalow. Because solar is sized to electricity use rather than floor area, use your own annual kWh from a utility bill, not square footage, to pick a system size.
