• PV system cost is estimated by dollars per watt installed ("installed" meaning all equipment, permitting, and labor necessary for complete installation). Cost for most of our roof-mounted, grid-tied installations around $8 - $9/watt.
• Typical grid-tied Residential Installations fall in the 4kW to 8kW size range; Commercial Installations from 15kW to 25kW and beyond.
• 100 sq. ft. of unshaded roof space (preferably, flat and south-facing) is required per kW of PV

System size (5kW = 500sq. ft. of roof; 25kW = 2,500sq. ft.).

• PV systems are modular and can be increased in size over time as your budget allows.

Approximate turnkey cost calculation examples for roof-mounted, grid-connected PV systems:

Residential 5,000W (5kW) PV System
5kW (5,000 watts) x $8.50/watt = $42,500 installed
(more or less - depending on mounting variables and system size)

Commercial 25,000W (25kW) PV System
25kW (25,000 watts) x $8.50/watt = $212,500 installed
(more or less - depending on mounting variables and system size)
