Renewable Energy Corporation

Renewable Energy Corporation is Maryland's oldest family-run solar energy company, having served the Baltimore region and broader Mid-Atlantic area since 2007. Over 19 years in business, the company has built hundreds of residential and commercial solar energy systems across Maryland, Washington D.C., Virginia, and Pennsylvania. Their longevity in a market that has seen dozens of solar companies come and go speaks to a business model built on steady execution rather than aggressive growth.

One of the company's defining operational principles is its refusal to use subcontractors. Every person who works on a Renewable Energy Corporation installation is a direct employee of the firm, fully accountable to the company's quality standards. That approach adds overhead costs that subcontractor-reliant firms avoid, but it also eliminates the quality control gaps that frequently arise when installation crews have no long-term relationship with the company whose name is on the contract. For homeowners investing tens of thousands of dollars in a solar system, knowing that the same company designed, installed, and will service their array provides meaningful peace of mind.

The company holds NABCEP certification and partners with QCELLS as a certified installer, giving their customers access to panels backed by a 30-year performance warranty. Renewable Energy Corporation installs exclusively American-manufactured products, a sourcing decision that aligns with both quality standards and the domestic content bonuses available under current federal tax incentive programs. Their service offerings extend beyond traditional rooftop solar to include solar attic fans, EV chargers, and battery backup systems.

Customer feedback has been consistently strong. A 4.7-star Google rating across 342 verified reviews positions them among the highest-rated solar installers in the state. Maryland's solar market benefits from favorable net metering policies, the state's Renewable Portfolio Standard, and generous Solar Renewable Energy Credits, and Renewable Energy Corporation's team has the experience to help homeowners navigate that incentive landscape effectively.

With a composite score of 80.64 out of 100, Renewable Energy Corporation holds the second-ranked position among solar installers in Maryland for 2026.
