Recommended Customer Reviews

Energy Saving Pros (ESP) installed an additional group of panels on our roof a little over seven years ago. While the work they did then was fine, last year I called them about our true up with PG&E being so high. They came and checked and replaced one panel on their system and when I asked them to check the inverter for the original unit, they said it would take someone else from their office to do so and said they'd follow up. We never heard from ESP and health issues kept us from following up. Almost two months ago I called ESP's office to pursue getting them out to check the inverter in question and was told I would need to pay a service fee of $99, which was reasonable. and it would be two weeks before a tech could be out. After not hearing from them, I called 3 weeks later and was told someone would be out the following week and the cost would be $225. When I questioned what happened to the $99 she said she'd check with owner and get back to me and she had me text her a photo of the inverter in question, which I did. As you guessed, I've never heard from them again. In the meantime, I contacted Capitol City Solar (CCS) who agree to come take a look but that it would be at least two weeks. No problem there as we've waited so long for ESP. A tech was out today, exactly 2 weeks after my call and guess what. The original inverter was not fully functioning due to a loose cable in a connection box that could have only happened when ESP installed the newer system. Huh, makes me wonder if they didn't know this was their problem and thus not willing to come check the system for me. I paid more to have CCS come but feel it was well worth it. If you want follow up with your solar system, I'd avoid ESP and go with Capitol City Solar.

Knowledgable, helpful and honest! I inherited a small rental home that I had never seen, but I knew it needed lots of deferred maintenance. Thinking it likely needs a new roof, I was ready to dig into my savings for the job. Xaviar of Energy Savings Pros drove out to the house to give me an estimate. To my surprise Xaviar said that the roof is in very good condition and well made. He also provided me photos of the roof and provided extremely helpful suggestions--add gutter guards, clean downspouts, hire somebody to blow leaves off the roof etc.--to give the roof maximum lifetime. I'm extremely impressed by Xaviar's knowledge, helpfulness and honesty. So impressed I hired Energy Savings Pros to do spring/fall check-up and maintenance on my heating and air conditioning at my home.

They had a rogue employee who earned them one star and my ire, but they did all you could ask a business to do - dismissed the employee and made it right.
They have been professional, quick to respond and follow up, and just easy to work with. Once we get the project done I'll follow up with an updated review on the work!

Like most people, my husband and I debated for some time whether to add a solar system to our home. We spoke with several companies and ultimately decided to go with Energy Saving Pros. Our consultant Tracy came out to our home and answered all our questions. She was there for us every step of the way. We felt the price was reasonable and we were confident with our choice of companies... especially since ESP had so many positive reviews! Now we know why. This company is there for you from the moment you schedule the consultation. Their install crew was on time and finished in one day. We couldn't be happier with our system!

Our pool solar started leaking and I asked Energy Saving Pros to come look at our system (that they installed) and see if they could fix the problem. Xavier took a look and said that 3 boots needs to be replaced but he only had 2 in his truck so he would have to come back. He also told me that our roof was a mess, 25 or more cracked tiles that need to be replaced and a possible situation where one tile has been moved and dry rot could be happening but wouldn't know more until he looked into it further when he comes back. He said he would send me a quote through email and that I should schedule his to come back ASAP before the rain starts. He also asked what my husband does and I didn't see why that was relevant but I told him.
I received a quote for $800 for the solar to be fixed and $3800 for the rest of the roof to be fixed (this did include a gutter) but a previous roofer gave me a quote for the gutter and it was $1200. I thought this was very high and almost payed to get the solar fixed. I contacted a couple different companies and Aztec came out for a second option. Aztec fixed our leaking solar for $85!!! He said, the boots just need to be tightened and he also saw a couple tiles that needed to be pushed back in (which he did and glued them) and said the roof looks perfect!
DO NOT TRUST this company!!!

Won't stop calling. 27 times!!!! Super rude on the phone. Just based on customer service I would go with anyone but this company.

It's a large investment to buy a solar system for your house. That is why I spent time investigating the variables and the questions to ask before selecting a company. There's a lot of good information online (i.e. energysage) and your friends and neighbors also have some great advice on questions to ask up front. I assembled about 20 questions dealing with warranty, materials used, installation, experience, certifications, etc. and sent my questions to a few solar companies. The sales manager at ESP sent me back a curt message saying they would pass on the project. What? I asked what the problem was and he proceeded to tell me that it wasn't in their process to answer such questions up front. Apparently questions about what materials they use and their efficiency, the warranty and such was too much ""in the weeds"" for them. It boiled down to them assuming that if a prospect asks questions (really, pretty easy questions) that they will be hard to work with and the company doesn't want their business. This manager said that asking detailed (and general) questions up front represented a ""classic red flag"" warning. This is THE MOST BIZARRE thing I have ever dealt with in my life! It certainly implies that they are hiding something and don't want you to compare with others. He went on to say that these 20 questions represented a preview of more questions that I may have along the way that will ""get in the way of us doing our jobs"". Excuse me, a customer can't ask questions up front nor along the way??? This is NOT the DNA of a company I want to do business with. Finally, here is a quote from him, made in his closing line: ""I want to wish you well, I know there's a company out there, hurting for business, that will be happy to get into the weeds with you, and then not deliver."" This elitist attitude and unbelievable handling of a prospect really showed me a great reason for not going further with ESP.
*Note: Jack is lying in his response. I never asked for a serial number. I asked questions straight from independent online sources. He calls questions about the efficiency of his panels and their warranty to be too micro. I was asking as a prospective buyer and was treated terribly. BTW, the second company already issued their answers timely and professionally. Finally, my reviews are never ""retaliatory"" but are a true reflection (good or bad) of the service I received from Jack C .
**Note: We just selected Magic Sun Solar - What a great company. Answered all our questions. Great panels (both Panasonic and LG) and they use state of the art micro-inverters! What a complete opposite sales approach they use. They were helpful, answered questions and even used their Solar Eye to predict the sun exposure across various positions on the roof. We felt like they really wanted our business. Simply put, they earned it. (Unlike this company ESP)

The process for us was long, from contract (24 Aug) to installation (started 30 Oct), although not full fault of ESP, it is one of the reasons for knocking off a star.
Brian at the office is great to work with, he is the boss yet it feels so right talking to him or asking advice. He does his best to answer all my questions patiently and worked through with me several issues that I had during the process. Kelly, the financial person, is also nice to work with, another person you can count on when you have questions!
I am recommending ESP to all my 52 neighbors who have yet PV solar installed because I am a believer of solar products.
30 Oct, Tuesday, was removal of my 6 old pool solar panels, and, first phase of PV solar installation, 8 hours. It was pleasant working with theses guys- Cameron, Raymond, and Cain. Raymond was patient to note some changes I like made on the solar placement on the roof, he very quickly had it resolved, he also with the knowledge of my roof gave me a sound advice as to how my new pool solar should be placed. Then it was Cameron. Upon my request, he agreed to place the inverter higher than he usually would, after it was installed onto the wall when I realized it was not at the height as we have first agreed plus the leveler showed it was a little tilted, Cameron took extra time and effort to rectify these issues quickly, making sure the inverter as a long term fixture in my home is a constant pleasant reminder of how he had made it right for my home. A total of 6 men worked, although I didn't get to know all their names individually, they all worked hard and well with one another, such spirit is important and you know when they work well together means they do better installation.
31 Oct, Wednesday, Cameron came back out to finish the wiring, 2-3 hours, I am please to have him around working on my property.
1st Nov, Thursday, Cain, Colby, and Raymond came back to install 6 of the new 12' pool solar panels. Good was that, Cain helped to pour some flex material onto a hole in the gutter.
5 Nov, Monday, Travis came out to install the attic fan which the earlier team missed to install, and to meet the county officer to have the solar plan approved. Unfortunately, my inverter had been upgraded to the 7600 series but the plan still shows 3800 series, the county officer could not approve the plan. Travis went into the attic, we got the best spot we thought the attic fan should get installed at. Travis left to quickly have the changed plan paper work submitted, he's coming come back another day to install the attic fan when he'd meet the county officer again.
8 Nov, Thursday, is when John, the pool man, is coming to install the new variable speed pool pump and new pool monitoring equipment. I've also ordered on the side an auto vacation pool filler.
Supplied by ESP:
-14 HanHua 320 watts PV solar panels.
-7600 series inverter upgrade with electric car charger.
-remove 6 older pool panels (2X12' + 4X8'), and install 6 12' pool panels.
-new variable speed pool pump
-new pool monitoring system
-attic fan

They have been great to work with. They were not high pressure like a few of my other quotes. They came in very competitively priced and will match prices if you can find anyone that can beat them. They are way better priced than going through Costco and they do a great job. The guys that came out are clean cut, professional, and polite. My wife had no issue being there alone with the work crew. They installed our solar and a whole house fan. Very happy with both. The only complaint is that it took a couple weeks longer than we had been told, to get everything through approval and to get on the install calendar. The install was done in a day and they fixed some broken roof tiles while up there. They got the inspection done and set up with PG&E all done within about a week of the install. Clearly they know the business as I have heard that some companies take a few weeks. If you have PG&E do your self a favor and at least get a quote from ESP. It will surprise you how fast the break even point is and the team will treat you well.

Excellent company. Good product great sales folks. After a year system is still a go with no issues.
