What goes into solar installation costs?
The total pricing of a residential solar panel system is composed of several variables. On average, a standard home installation in the US ranges between **$12,000 to $22,000 net** after applying the 30% federal tax credit.
1. Hardware & Components
This includes the solar panels themselves (monocrystalline vs. polycrystalline), solar inverters (string inverters, optimizers, or microinverters), racking, mounts, and electrical wiring. Hardware typically represents 35% of the gross cost.
2. Labor & Design Engineering
Designing a system that fits your roof slope, electrical panel capacity, and structural integrity requires professional installers and structural engineers. Labor accounts for roughly 30% of total costs.
3. Permitting, Interconnection & Grid Approval
Your local municipality requires building permits, and your electric utility must inspect and approve the system for a bidirectional net meter. Permitting and interconnection costs represent about 10% to 15% of the total expense.
