Tony P. | Leander, Texas | 09/22/2025

Solar Experts

Greenstar Power installed solar panels along with a new roof on our home in Leander. Just an incredibly great group of people to deal with. And they do know their solar, folks! The new roof and the solar installation were expertly done -- and quickly. Since then, any questions we have had have been answered by Nathan, and all the representatives who have come by to check/confirm the operation of the panels and equipment have been knowledgeable and courteous. Great product and great customer service. We have saved a fortune on our electrical bill.

Overpriced. Horrible communication/customer service

I have had solar for about two years now, without issue. Set up and install was a painless process. Communication was great! Fast forward to me receiving an outrageous electricity bill for two months. I let the 1st month slide thinking, maybe we did use more than the panels created. However, once I received the 2nd month's bill, I called into Greenstar. Turns out I have four panels not working. Well, that explains it. I then got the "you should have received an alert on the app". I explained to them that I checked the app and no alerts are populating. Sent in a screenshot, because at this point, they prefer text communication vs over the phone. They do their part to submit a ticket to have someone come check out the panels. I do not get any notification via email, text or phone call and someone shows up. Okay, fine. Problem. I speak English and no other language; this person does not speak English. I just show them where the main box is said ok for them to check it out. They are here for a couple hours then just leave. Not a word or no communication what's so ever from the office. I called into the office and was told they didn't have an update because no one updated them. Long story short, they just showed up again out of the blue about a week later and "worked" on the panels. Again, I have to be the one to call in to get an update-panels were swapped, should be good to go, could take 24hrs for the app to update. Fine. 3 days later-no change, I reach out, again told that once the serial numbers are updated, I'll see the changes. Fast forward to 4 days later... still no update. I call in and supposedly there is another issue that needs to be fixed. Great!! I ask, when can they fixed? not sure ma'am. you are 1 of 10,000 accounts we manage. So, here I am in month 3 of having to pay for the solar panels on top of huge electricity bills. Their whole customer service process is not beneficial to the consumer, only to the company because you are still liable for the costs of the panels whether they work or not.

Overpriced and nonresponsive.

I was sold overpriced panels. Also agreed to certain terms as we are on a fixed income, and was sent to a predatory lender. Terms are as agreed upon for 18 months and then go up if 30% of the loan is paid off. A detail not disclosed., and we made sure and asked if the payment was fixed. As long as you give them the tax credit and auto draft, the terms will stay the same, not true. The tax credit doesn't get the loan to the required balance, and the payments made thus far for the last 9 months, have gone to interest. There was no way to pay that amount down in 18months. We called because we were having trouble with the panels not all working correctly. They never called back. When we called for an estimate to remove them, we were quoted $17k to remove them and lay them in the yard. There is no way I would recommend this company amd I'm pissed they were recommended to me. Huge scam.

If the almost $10,000 tax return is a key reason you're thinking about going with this company, do not waste your time. It is a complete lie on their end. You WILL NOT get that when you file taxes. Trust me...

Highly recommend!

We just moved here from out of state and it is very overwhelming with the amount of door knockers that come to your new home as you’re trying to get settled and unpack get the kids back to school and obviously just live your daily life. The only company that stuck to our heads was not annoying, overwhelming and honestly just were real people selling what they love was green star. they did not hound us. I highly recommend if you choose to do solar call Scott at Green star. He is very knowledgeable respectable and definitely you can tell he’s a family man. Thank you so much the Clark family!

The Egg Shedd | Wimberley, Texas | 02/15/2018

Homeowner

This was a painless process. Considering crazy weather in Central Texas (ice and snow). Our project was a little unusual as it required the solar system install on the barn, but the energy conservation upgrades were added to our farm house that runs on a separate meter. The complexity of the project, caused some confusion with between site inspection and design, that needed adjustments, issues were resolved in a day and the project moved on. This team works great together. As the customer, we felt very comfortable asking questions that were technical and the answers presented in a manner we could understand. I was very impressed that the installers each and everyone, didn't mind if we interrupted them to ask a question, what they were doing, whether it was me, my husband or 12 year old son. The project install was complete in about 7 days (even with rainy weather). We are live and producing solar power! We can't really comment on after sales service as we have been live for a week. We did get bids from other companies that were comparable in price but Green Star's customer service from day one set them apart. Keep in mind that your power company, your choice of financing or form of payment, and your time restraints play a huge part in their job. As in anything communication is key and documentation (approvals, signature etc...) from the customer has to be timely as well. Great Job!
