Choosing a solar battery installer
Last updated 7/6/2021
Once you’ve received multiple battery quotes to compare, it’s time to pick the installer and energy storage system that’s right for your needs. When you select an installer, you want to know that it’s a reputable company, with a strong track record, that has all the appropriate licenses and certifications required in your state, as well as the specific training and certifications to be able to install the battery you want. Quite the long list!
Choosing between different installers can be a daunting task, but EnergySage is here to help. We thoroughly vet the installers in our Marketplace, present installer-specific differentiators in the quotes you receive on EnergySage, and have created an installer-tiering badge system that helps you find the top storage installers in your area.

What distinguishes the best installers
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: what's covered and for how long
In the unlikely event there’s an issue with your energy storage system, it’s important to know who to call if something goes wrong. There are multiple different warranties that come with your battery, 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 1 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, installers will rely on subcontractors to perform some, or all, of the work included during your storage installation. Don’t be put off by this: 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 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?
Every energy storage installation is unique, so it’s important to work with an installer who has experience custom designing energy storage systems to fit their customers’ needs. As you work with installers to design your storage system, be aware of how installers answer your questions about why they’re offering a specific battery, as opposed to a smaller or larger system. When you’re comparing your options, the best installers will work with you to understand your needs and how storage fits your overall energy plans.
