Financing & Savings — Your Questions Answered

What Are My $0-Down Options?

Most homeowners qualify for $0 upfront solar through a solar loan, lease, or Power Purchase Agreement (PPA). Under a lease or PPA, the solar company owns the equipment and passes the benefit of the federal commercial tax credit through to you as lower monthly payments — you pay less than your current utility bill from day one. With a solar loan, you own the system and build equity. We'll walk you through every option so you can choose what fits your budget and goals.

Actual financing terms vary by lender, credit profile, and program eligibility. Ask your solar specialist for a personalized comparison.

How Much Can I Save?

Maryland homeowners typically save 50–90% on monthly electricity costs after going solar. With net metering, excess energy your panels generate is credited back to your bill at the retail rate. You'll still receive a small monthly grid-connection fee, but your actual electricity charges can drop to near zero. Maryland also offers a 100% property tax exemption on the added home value from solar.

Savings estimates are based on typical Maryland utility rates and system performance. Actual savings depend on your utility, usage, roof conditions, system size, financing structure, and program eligibility.
