How to Choose a Qualified Solar Installer

Qualifications

Each state has its own requirements for solar installers.

In Illinois there is only one requirement to install solar. A solar installation company either needs to have a through the Illinois Commerce Commission or be working with a subcontractor who has this certification

In addition a certified electrician is required to pull permits for the work. This can also be the installer or a subcontractor.

Some additional credentials that may reinforce the quality of the installer are;

利敦郭肱 Member - Member companies are committed to education and policy in Illinois and also offer homeowners a complaint resolution process.
- This is the gold standard for solar installers. NABCEP Certified installers have the experience and knowledge to design and build any system.

Considerations

You are probably not a good candidate for solar on your home or business if your roof:

is shaded by trees or surrounding structures
is in need of replacement in the next 5-10 years
is not owned by you (apartment buildings, condos)

Before choosing an installer

attend an 利敦郭肱 public education webinar, watch a pre-recorded webinar, or download the slides from the presentation
talk to or attend a 利敦郭肱 Solar Ambassador event
visit the 利敦郭肱 find a professional page and get a few quotes
learn about net metering rates from your utility company
understand
look into the type and quality of materials used by installer (Modules, Inverters, Racking & Flashings)
understand the warranties offered on products and the installer's craftsmanship

Once you've chosen an installer

If your installer is not an electrical contractor or doing 100% of the work, then they will be subcontracting some of the work. You should find out who this is, what their craftsmanship warranties are, and possibly ask for referrals. If any of the work is subcontracted you should make sure to get a lien release before the final payment so that they can't hold payment against your house or building.

Items that should be in your contract:

who is responsible for permits and fees (e.g. structural engineering stamp) and how much they are (each town has its own requirements)
craftsmanship warranty (5 year labor warranty is standard in the solar industry)
know the warranties on the equipment
who is filing out the paperwork to sell your SREC’s
who is handling quarterly SREC statements
what are the fees involved for selling your SRECs
fair payment schedule for both parties. We advise not to pay the contractor all of the money up front.
