Amazing assistance

A neighbor recommended Karl Goodman, Solar advisor and so glad I got in touch with him. Karl went above and beyond to help me understand my APS bill and how my solars work. He also gave me recommendations on what plan is best for me and how my new pool settings can contribute to my plan. Absolutely so appreciative that he took the time to educate and help me. I recommend this company!

No response my solar had been out for2 month

My wife calls no answer. They told us twice they would come and install the part. Then no show. I would not recommend this company to anyone. They don’t answer their phones. They act like they will assist you with anything before you have your unit. Then afterward it is a ghost town.

Just TERRIBLE overall experience!!!

I started the process around June of 2022. The salesman went over a bunch of information very quickly and new the presentation well, but after doing research later and actually selling solar myself in Ohio, I quickly found out how much the salesman really did not know. During the installation, it took almost 8 months to get fully installed. During this process we found out that they had went through different installers because previous ones were coming to the job "high", which both my wife and I thought and was furious over because we had our kids in the same house as these people. After finally getting it installed and the solar starting to work, December of 2022 we started to get a leak in my daughter's room directly above where she sleeps. It took them almost a month to get someone to come out because now at this time, they were no longer selling in Ohio. The team that came out and "supposedly" fix the issue, but all they really did was put a bandaid on the issue. Fast forward to present, we are now dealing with the same leak issue because all they did was put some extra tare or whatever the heck they put around where they drill through the roof to get the panels secured. Now looking at the attic, the issue has gotten much worse and again currently dealing with the company to get someone to come out to use to not only fix the issue, but I am demanding them to remove the panels, reverse the financing on this and to fix the whole roof. Now we not only have a leak in that area, but other areas as well. This has been by far the worst experience I have had and really have no control over it. Now we are dealing with a mold issue since they did not fix the problem correctly the first time. Beware when using this company or really any solar company. You really need to do your homework on their installers because this has been nothing but a headache, figuratively speaking and literally speaking.

Disappear when you need them

They came into town and installed the solar panels, and the moment we needed them, they disappeared and won't respond. We have sent several requests to them to help solve our electrical issues that we have been having since the installation, to inspect the installation to ensure it is installed properly. They promise to replace your main power box when they install when it is not up to code, and the inspector said that it was needed, but they did not do it. We had to get it replaced because it was not up to code out of our own pocket and they falsely stated that it was up to code and threatened to void our warranty because we had someone else do the work. We told them we asked them repeatedly to come out and look at it and they denied the request and then said there was no record of our request. Noe we are still having issues and our monitoring company has asked them to come out and inspect and we can't get a response from Nerd. They aren't following through on their warranty and have no customer service. They won't even work with BBB. Please avoid this company

NO SHOW appointments.

We recently have issues with solar. The water heater, dryer and other appliances are not getting enough power. We called them to come out and check what's going on with the solar. The solars are under warranty. We scheduled an appointment with them; they did not show up. Took another appointment. Canceled in the last minute; the reason was a technician's family emergency. Scheduled again; no show. It's been a month; and not getting anything fixed. This company should not be in business.

I was lied to. One of the worst purchases I ever made

I wish I never hired Nerd Power. They quoted my system at $24,000 saying it would be enough to power my house. After several months of repeated failed inspections by SRP the system is up and running. Nerd power billed me an ADDITONAL $2500 for the labor. The saddest part is that now I can see that my system is producing less than 1/3 of the energy needed to power my house. Rather than saving $ and the solar panels paying for themselves, I have effectively doubled my electric bill for the next 25 years.

Terrible experience, I would give zero stars if I could

Adding solar power to my home and using NERD Power as the contractor are two of the biggest mistakes I've made in my life. High pressure sales. I am sure I paid too much for what I got in return. Customer service became non-existent after installation. They promise you will be able to monitor solar output from your smart phone or tablet. When that stops working, you are simply out of luck. I was told to completely reset my inverter system. When that failed to resolve the issue, I was told the only option at this point is to update/re-install the application, That didn't work either. They promise a system whereby you can monitor power usage by circuit called Curb app. When that failed I learned they have a new vendor and even though my system is under warranty, Curb is not included and it's a $125 service fee for them to come out. I've asked for help on numerous occasions and now am getting no response at all. You are much better off furnishing your home with energy efficient appliances and HVAC systems than going solar. If you do decide to install solar, do NOT use this company.

Do your research..

I probably should've done more research about solar in general, granted they helped lower my bills in half, but not, all at the same time because of the payments..

If I could give 0 stars I would

I am so disappointed in this. I was so excited to get the panels installed and everything. Was told my panels would produce 8.8kw. Not true, I used 10.3 kw for the month and got a $404 bill. I called Nerd Power and they said the panels are working like they should. Now I’m stuck with these panels for yrs to come and more than double electric bills. The sad thing is this was my first month with the panels. If a class action lawsuit comes up count me in.

will not recommend nerd power to anyone

Very disappointing experience and we'll not be recommending nerd power to anyone. Signed contract in September 2022. They installed panels late December and were supposed to be operational in January 2023. SRP inspection failed because inverter was not working. Nerd power came relatively quickly to change it and SRP approved everything. Except that 2 weeks later, inverter broke again. The app was not working either and no one informed us we were off grid until we received our first SRP bill a month later. After having to call and inform nerd power of the issue, it took them over a month to get the piece and to come repair. We were told that they would install a more powerful inverter cause it was already the 3rd one they came to install. However, they never upgraded the inverter as we found out 4 months later and inverter broke again. Once again, no one contacted us to let us know we were off grid, again. When calling nerd power, no one knows anything. We were told weeks of wait to even receive the same new piece which is obviously not working. In the meantime, we are being charged $$$ from SRP while solars are not working. We are actually losing money instead of saving money like they promised we would installing solar. Total of month solar being install and supposed to be running 6 months, total of months actually working 3 months. No help or compensation were offered during these months being off grid.

Slow process and high prices

I paid 42k for a 9.45 KWh system and opted out of most of their home efficiency options. I soon realized I way over spent. Also, it took 13 months from the day I signed till the solar panels were producing. Overall the people were nice but, I paid twice the amount and was further on lied to about how large of a system I can have . Turns out I could have gotten at least a 15kwh system and could have gotten monocrystalline panels for the same price as I paid out. I guess Nerd power is happy though, they made over 20 thousand dollars off of me.
