EXCELLENT Based on 225 reviews Posted on Danny Yadgir Alex and his team were great! After the free estimate, he shared any immediate concerns or recommendations for the project. They arrived on time and completed the work quickly and professionally. Alex provided regular progress updates and ensured we were aware of any changes. They went above and beyond to keep the workspace clean and were respectful and personable. I’d highly recommend Lehmann Electrical & Design for their clear expertise, attention to detail, efficiency and fair pricing — with results you can depend on.Posted on Hiram Siaba Great service, follow up and work. Thank youPosted on Scott Folger Great experience. Nice technician. Fast and efficient.Posted on Nick Vollendorf Service was prompt and efficient, estimator explained the job and options well.Posted on Michael Lehmann Jacob and his crew are amazing at what they do.

Super happy with their work and professionalism.Posted on Patrick McRae Drew did a great job installing our charger. Very clean and efficient.Posted on David Peters-Behm Always on time and professional, Alex was great as well! Would highly recommend to anyone. We will not use anyone else!Posted on Mary Henkle Alex and Ty were neat, efficient, easy to explain my electrical needs to and, were willing to change the electrical route of the unknown. I love the under eaves lighting in lieu of the passe carriage lampsPosted on Charles Conto My leasing company had Lehman come out to troubleshoot some outlets that mysteriously stopped working and some switches that had "blown up" over the weekend at our rental. Couldn't be more happy with who they had hired. Jacob (or Jason, I apologize if I got your name wrong) was timely, professional, and nice to chat with. He identified the issues with our switches and an overnight light fixture that was never installed correctly, and got them fixed promptly. In the future, hopefully as homebuyers and not renters, we hope to use Lehman for our needs. Thanks again!Posted on Robert Hawthorne Great local company to work with. Alex was very professional and got the job I needed in good time. I'm sure I'll be using Lehmann's again for future projects.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Frequently Asked Questions
What is the typical payback period for solar in Illinois?
Typical: 12–16 years (based on calculator showing ~12.8 years for 13 kW system generating $1,969/year in savings). Your actual payback depends on electricity consumption, local rates, system size, and available incentives.
How does Illinois Shines work? Will my RECs be sold?
Yes. Illinois Shines is a state program paying you for Renewable Energy Credits (SRECs) your system produces. If your system participates, the RECs are sold to utilities—you cannot claim environmental benefits. Your benefit is the upfront SREC payment ($3,000–$10,000+) plus reduced electricity bills. Enrollment subject to program capacity and approval—not guaranteed.
When do I receive the 30% Federal Tax Credit?
Do I need to own my home to install solar?
For ownership + tax incentives: Yes. You must own your home to claim the 30% Federal ITC and qualify for most incentives. Renters can participate in community solar programs (credits on electricity bill) but don’t own systems.
Can I add battery storage after solar installation?
Yes. Your solar system can be designed to accommodate battery storage (Tesla Powerwall) later. We design systems with future expansion in mind. Adding storage is typically straightforward, though electrical modifications may be required.
How long does installation take?
On-site installation: 1–3 days. Full timeline (consultation to activation): 8–12 weeks, depending on permitting speed and utility queue. We maintain transparency about timelines throughout.
What is your warranty? What's covered?
1-year workmanship warranty on our installation. Equipment manufacturers provide separate warranties: 25–30 years for solar panels, 10–15 years for inverters. We manage all warranty claims. Does NOT cover manufacturer defects, weather damage, or customer misuse.
What if I move? Can I take the system with me?
If you own the system: Solar systems are transferable to new owner. If you lease or have a PPA: Terms vary some transfer, some require buyout. Your contract specifies. Battery systems (Powerwall) typically transfer as well.
Is Lehmann affiliated with utilities or government?
No. Lehmann Electrical is an independent solar installer and electrical contractor. We are NOT employed by, representing, endorsed by, or acting on behalf of any utility, utility program, consumer group, or governmental body. We are an Approved Vendor under Illinois Shines (state incentive program).

Your Renewable Energy Credits (RECs) & Environmental Attributes
If your system participates in Illinois Shines, the renewable energy credits (RECs) generated by your system will be sold by Lehmann Electrical to Illinois utilities. This means:
- You will NOT receive the environmental benefits of your system's generation.
- You cannot claim your system uses "clean" or "renewable" electricity.
- Environmental attributes belong to the utilities that purchase the RECs.
- Your primary benefit is the upfront SREC payment from Illinois Shines and reduced electricity costs.
Important Documents You Will Receive
- Illinois Shines Informational Brochure: Describes the program, your rights, and incentive details.
