What to consider when choosing a solar company
When you’re exploring your options for solar in Massachusetts, there are many factors to consider. Be sure you weigh all of the following as you make your plan:
- Price: Compare providers to the average cost of solar panels in Massachusetts. It’s helpful to compare this in terms of price per watt.
- Location: Is your installer local, or will you be working with a third party that the company contracts?
- Customer reviews: Be sure to compare reviews in terms of pricing, equipment quality, warranties, installation time, and customer service.
- Experience: How long has the company been in business? What kind of experience does it have on its team?
- Financing options: If you don’t plan to pay cash for your system, you’ll want a provider that offers financing or leasing options.
- Warranty terms: Most providers now offer a 25-year warranty on equipment and around 10 years for service. Make sure the warranty coverage provides adequate coverage and peace of mind.
- Services provided: Installation is only one part of the equation when comparing the top solar companies in Massachusetts. Look for companies that provide full support throughout, from permitting until you’re online.
- Average install time: Ask installers how long the entire process takes and what you can expect on installation day.
Difference between a solar broker and an installer
Before you begin comparing the top solar installers in Massachusetts, it’s helpful to understand a key distinction. When you connect with solar companies, you may interact with two different entities: brokers and installers.
Brokers handle the sales side of the transaction, helping you plan your installation and compare equipment and financing options. Installers, meanwhile, handle the work of installation. In many cases, brokers don’t have their own in-house installers, meaning you could be dealing with an entirely different company after the sales transaction is over. Be sure to clarify how this is set up with the company before you get started.
