Solar panels cost about $18,300 to $36,400 for a professionally installed residential system in 2026, with typical pricing around $2.50 to $3.50 per watt depending on system size and equipment.
Solar panel installation costs $18,297 to $36,409 for a typical U.S. home in 2026, with an average project around $27,129, depending on system size, equipment, roof condition, and location.
Solar panel cost per watt typically falls between $2.50 and $3.50 per watt for a professionally installed residential system in 2026, a better way to compare proposals than total price alone.
Solar panel cost increases with system size: a 4 kW system runs about $10,000 to $14,000, a 6 kW system $15,000 to $21,000, and a 10 kW system $25,000 to $35,000 in 2026.
Solar cost per kWh measures how much a solar system costs against the electricity it generates over its lifetime, a better way to evaluate long-term solar economics than installation price alone.
Residential solar panels typically cost $18,300 to $36,400 for professional installation in 2026, with an average home project around $27,100.
Solar panel roof installation typically costs $18,300 to $36,400 for a residential system in 2026, with roofing material, condition, pitch, and mounting method changing the final price.
A typical residential solar project costs roughly $18,000 to $36,000 nationally, but identical system capacities carry different installed prices across California, Florida, Ohio, Washington, and other states.
A solar panel cost calculator estimates project price by multiplying required system capacity by expected installed cost per watt, then layering in roof, electrical, and battery costs.
How It Works
Four steps, one team, no subcontractors. Most installations are complete within three weeks of survey.
01
We assess your roof, orientation and current usage to size the system properly.
02
You get a panel layout, yield forecast and payback estimate before committing.
03
Certified engineers fit and commission the system, usually in a single day.
04
Track output from your phone, with annual servicing and support included.
FAQ
Still unsure which system suits your property? Talk to an engineer, not a salesperson.
Get in TouchMost residential systems are fitted in a single day. Larger commercial arrays typically take two to five days depending on roof access.
South-facing roofs perform best, but east and west orientations are viable too. The free survey gives you a yield forecast specific to your property before you decide.
Panels still generate in diffuse light, at reduced output. Pairing the array with battery storage covers the shortfall and evening usage.
Very little. An annual check and occasional cleaning is enough. Every install includes monitoring so any drop in output is flagged early.
