How we determine the best solar companies in District of Columbia County, DC

At EnergySage, we care about connecting solar shoppers to high-quality solar energy companies. As such, any solar installers we list above are active on the EnergySage Marketplace in District of Columbia County, DC and are pre-screened by our team.

What does it mean to be “pre-screened”? We evaluate every solar panel company to ensure that they’ll provide quality service to EnergySage users. These high-quality installers are approved based on their years of experience, licensing and insurance, reputation, and certifications. When bringing new installers into the EnergySage Marketplace, here’s how we ensure our partners are the best of the best:

  • At least three years of experience installing solar
  • Licensed and insured for solar installations
  • NABCEP certified
  • Reputation for excellent customer service and quality solar installations
  • Installs high quality solar equipment

Our rating tiers

Choosing the right installer can be difficult, especially when you’re deciding between multiple top-notch companies on EnergySage. To make it easier, we created a unique rating system that evaluates our partners’ performance based on real data from our Marketplace.

Elite+ installers are the most experienced, chosen, and celebrated companies on the Marketplace, having provided exceptional service to a high volume of shoppers for at least a year.

Elite installers earn top ratings from customers, endorsements from vendors, and win customers more frequently than their peers.

Advanced installers are among the top half of companies on the Marketplace for responsiveness, reputation, results.

Approved installers passed our rigorous screening criteria for experience, licensing, and positive reviews.

How to pick the best solar installer

When you’ve already narrowed down your options to reputable installers and are trying to decide which quote to move forward with, here are three final considerations that distinguish the best from the rest:

workmanship warranties for solar panels

Workmanship warranties

What is covered and for how long?

In the unlikely event there’s an issue with your solar panel system, it’s important to know who to call if something goes wrong. There are multiple warranties that come with your solar energy system, from manufacturer warranties for different components to workmanship warranties from your installer.

The workmanship warranty is specific to the work the installer performs, and is typically somewhere between one and 10 years. Be sure to check with your installer to see what’s included in the warranty, if there are any exclusions, and if there’s any cost to you in the event they have to come out and check on or replace some equipment.

The use of sub-contractors

Which crew will install your system?

In some instances, solar installers will rely on subcontractors to perform some, or all, of the work included during your solar installation. Don’t let this put you off: it’s entirely standard procedure in the industry. What is alarming, though, is a lack of transparency from installers about who will install your system and why they use subcontractors.

When you’ve narrowed down your list of potential solar installers, be sure to ask who will install the system–their own crew or subcontractors–and, if they use subs, ask why they do, what portion of the install the subcontractors will complete, and what oversight the company you purchase your system from has over the subcontractors. At the end of the day, the most important question is who will stand behind the quality of your installation.

Expertise

How does each installer tailor their system to your needs?

Beyond ensuring that your solar installer has all of the appropriate licenses and industry-specific certifications, it’s important to work with a solar installer who has experience custom designing systems to fit their customers’ needs.

When you’re comparing your options, the best installers will work with you to understand your needs, as well as how solar fits your overall energy plans. Make sure your solar installer provides a consultative, professional solar experience, and if you’re also purchasing a solar battery system, they have proven experience with those products too.
