Advanced Solar has been serving the greater Washington, D.C., and Maryland region from their Landover headquarters for 17 years. In a market where homeowners are educated, demanding, and have plenty of options, Advanced Solar has consistently risen to the top through technical competence and customer-first project management.
What earned them the number one ranking in Maryland was the breadth of their experience and the consistency of their customer outcomes. Their 4.8-star Google rating from 416 reviews demonstrates satisfaction across a high volume of projects in a region where expectations run high. The D.C. suburbs attract a technically savvy homeowner base that asks tough questions about system design, equipment choices, and production projections, and Advanced Solar clearly handles those conversations well.
The company is NABCEP certified and takes advantage of Maryland's strong solar incentive portfolio, including SRECs worth approximately $50 per 1,000 kilowatt-hours produced, a sales tax exemption, property tax exemption, and net metering at retail rate. Their team guides homeowners through this layered incentive structure and helps them understand the true cost of ownership after all benefits are applied.
Advanced Solar's Landover location gives them easy access to Prince George's County, Montgomery County, Anne Arundel County, and the broader Baltimore-Washington corridor. They handle both residential and commercial installations and have earned a reputation for meeting timelines in a region where permitting can be unpredictable.
With a composite score of 85.6, Advanced Solar is our top-ranked solar company in Maryland for 2026.

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.

Solar Energy World has been a fixture in the Mid-Atlantic solar market since its founding in 2009, operating from its headquarters in Laurel, Maryland with additional offices in Alexandria, Virginia, Pennsauken, New Jersey, and Tampa, Florida. Over 17 years, the company has built a regional reputation as one of the most established solar installers between Washington D.C. and Philadelphia, serving Maryland, D.C., New Jersey, Pennsylvania, Virginia, and Florida.
Like its Maryland competitor Renewable Energy Corporation, Solar Energy World operates with an all-employee installation model, never hiring subcontractors for any phase of the project. Every person who touches a system is a direct employee, giving the company full control over scheduling, quality standards, and customer communication from consultation through interconnection. The company also handles all incentive paperwork on behalf of their customers, ensuring homeowners receive the full value of available tax credits, rebates, and grants without navigating the bureaucracy themselves.
The company's review volume is among the highest of any solar installer in the state. A 4.6-star Google rating across 899 verified reviews provides a statistically robust picture of customer satisfaction. That volume means the rating is unlikely to be skewed by outlier experiences. Satisfied customers frequently cite the professionalism of the sales team, efficient installations, and responsive field managers who advocate on their behalf when permitting or utility issues arise. Where criticism appears, it tends to focus on occasional delays in post-installation service scheduling, a pattern that likely reflects the strain of managing a large project volume.
Solar Energy World's geographic footprint gives them exposure to multiple state incentive programs, and their experience navigating Maryland's Solar Renewable Energy Credits, net metering policies, and the federal Investment Tax Credit gives homeowners confidence that their system economics have been accurately projected. For customers who value working with a company that has handled hundreds of installations in their specific utility territory, that track record carries weight.
With a composite score of 71.7 out of 100, Solar Energy World earns the third-ranked position among solar installers in Maryland for 2026.

*Companies displaying 15 or more years in business are typically established electrical, roofing, or general contracting firms that expanded into solar installation in more recent years. The years shown may reflect the age of the parent organization or a strategic partner, not necessarily the solar division itself. This distinction is worth considering when comparing to dedicated solar installers, as purpose-built solar companies may offer more specialized expertise despite a shorter operating history.
