Excellent company to work with.

After getting at least six other quotes, I picked TigerSolar to do the solar panel installation. From the first interaction, they seemed like the most honest and straightforward company to deal with. In addition, the quote came in as one of the lowest. I'm delighted with the service received and how everything turned out.

Great company

I used the Michigan branch and had a great experience. They were honest and really cared about making sure the full experience was good. I had a small install, so many people no-quoted me since it wasn’t worth their time. Tiger gave me decent pricing and was helpful the whole time. The install was super clean both on the roof and at the panel.

Great Team

From the moment I requested a quote online the team was quick to respond and fulfill their promises. The quote was resonable, took my personal finances as well as physical requirements from my municipality into account. The design was not obtrusive and met all local requirements. The service was great with the team onsite as well. They were friendly, trustworthy and courteous with me and my family. The system works wonderfully and my electric bill is almost negligible (with only my standard service fees applying.) The online data is intuitive and helps share the progress with others.

Lots of options, Glad I went with Tiger

I had quotes with 4 different companies. Some through EnergySage and some on my own. Some were extremely pushy high pressure sales that were too expensive and made the "Manager" call for discounts. Tiger was easy to work with, low pressure, high knowledge, and helpful to get the sale. Once we signed after getting the right system, nothing changed. They were easy to work with, professional, and the job looks fantastic like its always been there. I would highly recommend them for anyone looking. I am an research nerd when shopping for anything but especially a higher end item like solar. It worked out great with this one. I highly recommend Tiger Solar!

The right choice

In January 2022, we contracted with Tiger Solar for an installation of 22 - 450 watt solar panels mounted in our field; and a Solar Edge inverter producing 9.9 KW DC (11.1 KW AC). Winter was more difficult than usual in Michigan and the system was installed and activated on June 20, 2022. While we have not seen our first bill from Consumers Energy, information from the Solar Edge inverter has shown us that our average daily energy production for the first 3 weeks in July is 53.48 KW. In reviewing our billing records for the past 5 years, our average daily electric usage was 43.58 KW. We have had more than the normal amount of rain in July, so even with cloudy days, we have more than met our electrical production expectations for the month. Our average electric demand for December drops to 26.3 KW, so we believe that the solar panels will still produce enough electricity for our needs as the weather changes. We acted as the general contractor when we built our house. The Tiger Solar installation team was one of the best sub-contractors that we have encountered. The installation was completed in 4 days. Coordination with their electrician and Consumers Energy could not have been better. Questions on the operation of the solar inverter were answered within the day. Congratulations to the Tiger Solar team for a job well done! The price of propane has increased $800 per year. Our next project is to remove the hot water tank from the boiler, and install a 55 gallon electric hot water heater to use some of the excess electricity.
