EcoWatch Criteria for Selecting the Top Solar Company in Delaware

The EcoWatch solar pros use a detailed process to find the top solar installation companies throughout the U.S. Finding the best home solar companies in each state isn’t an easy task. Here are some of the top criteria we take into account when narrowing down which installers to recommend. You can learn more on our methodology page.

Warranty

For many homeowners, an excellent warranty is a big selling point. Consider this: A company that believes in its products and workmanship is much more likely to offer fantastic warranty coverage than a company that is dubious of its workmanship or products. Companies that have great warranties proudly showcase them on their solar quotes.

Workmanship warranties generally cover anything that relates to the company’s installation. For example, if the solar panel falls off your roof because a technician forgot to tighten bolts, that is covered. Or, if your shingles are damaged during the installation and your roof leaks, that can be covered.

Product warranties often come from equipment manufacturers. Typically, this warranty covers anything related to defects and performance of the photovoltaic (PV) system and its individual elements.

Year Founded

The year a company was founded can be a strong indicator of its experience. Generally, older, well-established solar panel system providers offer a wealth of experience and knowledge in the solar space. With many years of experience, these companies are often well-versed in all things solar.

Some newer companies can offer strong services as well, although there are several unscrupulous and inexperienced pop-up solar providers out there. It’s important to pay attention to all aspects, including the founding year.

Services Offered

While most solar companies offer just basic solar panel installations, others go as far as to offer roofing services, electrical services and other home energy-efficiency upgrades.

Additional services can prove to be a beneficial advantage for homeowners, particularly if an issue arises. For example, if your roof requires repair before installation, a solar company that also offers roofing services may be able to handle it for you.

Solar Panels Offered

Typically, solar providers have a few solar panel brands to choose from, including a mix of high-end options with a few mid-range options. The best solar companies have the resources and materials to handle any solar project, regardless of how big, small or unique it is.

Here’s an example of why this matters: Solar panel costs vary by brand, but so does energy efficiency. The more sunlight your panels can convert into power, the lower your energy bills will be. The most efficient panels in the solar industry are only offered by a few installers, so if you’re set on maximizing your energy production, you’ll want to look for a company that offers highly efficient equipment brands.

Solar Pricing and Financing

The best solar companies in Delaware usually offer competitive pricing and multiple solar financing options. Many times, homeowners cannot afford to pay for their solar energy systems entirely upfront, emphasizing the importance of financing options like low-interest loans and leases.

Offering a variety of financing options can better accommodate the needs of various budgets. Above-average installers will also help you save money in other ways, explaining all of the solar tax credits, rebates and other incentives you qualify for; how net metering through your utility company can further offset your electricity costs; and the benefits of SRECs (Solar Renewable Energy Certificates).

In addition, these companies usually offer competitive rates without sacrificing any other part of the process, such as quality of products or workmanship, or even customer service.

Industry Affiliations

Most legitimate solar installation companies have affiliations with organizations throughout the industry. Industry affiliations and certifications we look out for include those with the Solar Energy Industries Association (SEIA) and the North American Board of Certified Energy Practitioners (NABCEP). Additionally, we look at local- and state-level renewable energy group memberships. As we begin to shorten our list to a few top picks, we consider this major aspect.

Size of Company

Solar companies come in various sizes, with some serving a single city or county and others extending services across the entire U.S. In some cases, larger/national companies can serve customers quicker or more efficiently than smaller competitors, given the larger team on hand.

In addition, these companies can sometimes offer better, more affordable rates, which some homeowners prioritize. However, they can also lack the personalized service and local knowledge of smaller companies.
