How to evaluate Unity Solar Group

Before hiring Unity Solar Group for solar work in Oak Brook, take a few minutes to verify their qualifications and confirm they are the right fit for your project. The right solar for one homeowner may not be the right fit for another, so do the diligence up front.

Verify licensing and insurance

Confirm that Unity Solar Group carries an active IL contractor license appropriate for the scope of work, plus general liability and workers’ compensation coverage. Ask for the license number and look it up on the state board website. A solar that hesitates to share these details is a red flag, regardless of how favorable their reviews look.

Get a written, itemized quote

Request a detailed written estimate that lists materials, labor, permit fees, timeline, and payment schedule. Itemized quotes make it possible to compare Unity Solar Group side-by-side with other solar options in Oak Brook, and they protect you from scope creep once the work begins.

Ask about project experience

Ask Unity Solar Group how many projects similar to yours they have completed in the last 12 months, whether they will be the primary on-site team or are subcontracting, and how they handle change orders. Request two or three local customer references and actually call them — reviews on Google are useful but a five-minute conversation reveals much more about how a solar actually shows up.
