As more homeowners and businesses in the Mid-Atlantic region consider switching to solar power, one of the most common questions is: How much do solar panels cost? The answer depends on several factors, including system size, state incentives, and local installation costs. In this guide, we break down the average solar panel costs in Maryland, Virginia, Pennsylvania, and Washington, D.C., to help you make an informed decision.

Understanding Solar Panel Costs

The cost of solar panels is typically measured in dollars per watt ($/W), with the average residential system size ranging from 5kW to 10kW. Prices vary based on labor costs, permitting fees, and available incentives. While national averages hover around $2.50 – $3.50 per watt before incentives, the Mid-Atlantic region has unique pricing structures due to state policies and energy market conditions.

System size: Larger systems cost more upfront but offer greater long-term savings.
Roof complexity: Installations on steep or shaded roofs may require additional costs.
Labor and permitting fees: Costs vary by location and local regulations.
Battery storage: Adding a battery backup, like the Tesla Powerwall, increases costs but enhances energy independence.

Why Choose a Local Solar Installer?

Choosing a reputable local installer ensures that your system is optimized for regional climate conditions, utility regulations, and available incentives. Unlike national chains, local installers provide personalized service, faster installation times, and expertise in Mid-Atlantic-specific policies.
