How System Size Affects Solar Panel Costs

Bigger systems cost more total but less per watt due to economies of scale. Here’s how to determine your optimal size:

Calculating Your Needed System Size

Find annual electricity usage (kWh on utility bill)
Divide by local sun hours (4-7 hours depending on location)
Account for system efficiency (multiply by 1.2-1.3)

Example: 12,000 kWh ÷ 5 sun hours × 1.25 efficiency factor = 3,000 watts (3 kW)

System Size Cost Comparison

System Size	Panels Needed	Roof Space	Annual Production	Total Cost (After Credits)
3 kW	9-12 panels	200-300 sq ft	3,600-5,400 kWh	$6,300-$8,400
4 kW	12-16 panels	300-400 sq ft	4,800-7,200 kWh	$8,400-$11,200
6 kW	18-24 panels	400-500 sq ft	7,200-10,800 kWh	$12,600-$16,800
8 kW	24-32 panels	500-650 sq ft	9,600-14,400 kWh	$16,800-$22,400
10 kW	30-40 panels	650-800 sq ft	12,000-18,000 kWh	$21,000-$28,000

Pro Tip: Don’t oversize your system beyond 110% of annual usage. Many utilities limit excess solar credits, and the ROI decreases on oversized systems.
