Never Go Dark: All you need to know about Battery Backup Systems & Battery Energy Storage Systems

Great company, wonderful people.

The technician, Clayton, who fixed the problem was knowledgeable and personable. He explained what he saw as the issue as to why my air conditioning and well didn't work after a power outage and the house switched over battery backup. He showed me the adjustments he made that cured the problem.

We’ve bought two rooftop solar systems from Sol-Tek Solar and got great equipment and service both times. Makes sense to have Sol-Tek Solar do periodic panel cleaning.

Easy to work with, very happy with the service!

Always polite and explain what is to be done, answered my questions regarding Enphase. Being older I have never been made to feel like I am lacking in knowledge. This company has always gone above and beyond to help me. A definite 10!

"Our inverter wasn't working correctly. After repeated calls to solar companies and electricians I called Fronius who referred me to Sol-Tek. They were fantastic!! I received a call from their technician that same day and had my replacement inverter within a week. The next morning when it didn't turn on I called and Sol-Tek was here, again, the same day. The technician called Fronius and asked for another one and shut the defective one down. Today Thomas came out to install the new one. He was very nice. I was working on something in the garage and we conversed amicably while we both worked. The entire company is chock full of nice people who know the meaning of great customer service. They are now my go-to company for any solar-related issues."

"Just had them do our solar and was super impressed. They were here exactly when they said they would be. Got the job done way quicker than I expected. They met the county inspector and supplied all the information. We passed with no problems. We were up and running way before expected. They did a super clean job. All of their employees were super polite and professional. I'm recommending them to family and friends."

"We trusted this company and only got their bid! The job was done quickly, they even came out on a Saturday and we were up and running in no time! Our system was perfectly designed for our home and our end of year #1 true up was .15 cents!!! This year we got a little crazy with the thermostat and still only owe PG&E $397 at the end of the year and we haven't made a PG&E payment since March 29th."

"Our panels were dirty as hell due to the recent fires. Our PG&E true up cost more than my first car. A friend recommended Sol-Tek so I leveled up and called. They cleaned my panels to a spit shine. This noticeably increased our solar output. Now I'm inside with AC on wearing a sweater."

"I have used Sol-Tek for many many years. They service my pool solar in the Spring to get my system up and running and then again in the Fall to turn the system off and drain panels. They have always been professional and very reliable. I highly recommend them!"

"I appreciate the communication and the service that Sol-Tek provides very professional and honest would recommend this company to everyone thank you so much Sol-Tek"

"We had Sol-Tek install a solar water heater several years ago. Their information was spot on. The water heater has greatly saved us on the cost of propane. We actually turn the water heater pilot light off during the heat of the summer and always have hot water. They are always helpful when we call and the service guys are fantastic. We plan to have them install a solar water system for our pool before next spring. And we really like that they are a local company. I recommend them to anyone interested in installing solar."

"Although I did a 4.7 kW system they gave me a great price. They installed micro inverters which last 25 years and give the best output if shaded. They I believe are safer no high voltage DC. I asked for the system to be installed before NEM 3.0 and they put that in the contract. Had to wait some time for installation but all solar companies have this limitation. Installation went quickly. System looks nice and wiring is not shown. Workers were nice and no trash left. John, the salesperson, explained... how monitoring works (Enphase). I would highly recommend Sol-Tek for your solar for me they did a great job. Looking forward to saving money. Robert​"

"This company saved my solar water heater when the roof installers dismantled it incorrectly. The staff were professional and efficient, and even corrected some other installation problem with the solar panels that were re-installed post new roof by the roof company contracted solar installers (who could not re-assemble the aforementioned solar water heater, and I had to hire Sol-Tek)"

"We were seeking an affordable way to heat our small pool, so we called Sol-Tek. They gave us an estimate and time frame that worked for us. It took less than one day for them to install the unit on our roof and we were able to enjoy the warmer water almost immediately. The youngest and oldest members of our family can now feel more comfortable in our pool!"

My wife and I have purchased two rooftop residential solar systems from Sol-Tek Solar, based in Clovis. Our first system paid for itself on our Fresno home in under 5 years. System worked flawlessly. When we moved to Clovis about 6 years ago, first thing we did was contact Sol-Tek Solar to install a new system on our new home. Haven't done the math, but pretty sure our 2019 system has already paid for itself. But recently, we noticed four of our 20 panels were underperforming; each of the four panels was generating about 25 percent less electricity than an average panel. Sol-Tek Solar came out, verified the problem and submitted a warranty claim to the manufacturer. With a 20-year warranty, no problem, right? But the solar panel manufacturer was now under a new owner, and the warranty service provider had changed ownership twice. But Sol-Tek Solar stepped up. When the manufacturer and the warranty service company were less than responsive to requests to replace the faulty panels, Sol-Tek Solar replaced the four underperforming panels out of their own pocket and will continue to seek reimbursement from the manufacturer. Didn't cost us a dime. This is what great customer care looks like. I don't hesitate to recommend Sol-Tek Solar to my friends and neighbors. Five stars in my book

"We used Soltek Solar for our house solar and pool solar, and we're very happy with the results. The crew was on time, respectful, and explained everything clearly. The system looks great and works perfectly. It's been a huge upgrade for our home, especially the pool heating. I love that they're a local company -- the customer service is amazing and you can really tell they care. I'd absolutely recommend Soltek Solar to anyone in the Fresno / Central Valley area."

"Outstanding customer service and attention to detail"

"Sol-tek was quick and helpful when I asked for an estimate and questions about their product. Great customer service"

"Great service! From the design to the installation. The app they provided to monitor my solar production is very helpful as well."

"We have been Sol-Tek customers for the past five years. We like that they are a local company. They have always provided good service at an affordable price."

"Top notch! Very professional, timely, and made the process very easy from start to finish. Check their rating on the BBB and you'll be happy you chose them before jumping into the Solar game."

"The best advice I can give you is to talk with John L. or Paul A. at SOL-TEK before you make your decision on a PV Solar system for your house or business! Excellent Staff! Quality Work!"

"I needed solar cleaning and found Sol-Tek online. The service was prompt and professional. The cleaning significantly improved my panel output. Glad I found them."

"John L at Sol-Tek helped us last year secure solar, and after year 1 I couldn’t be happier with our choice. Sol-Tek and John were great to work with and made going solar a super easy and seamless process. Thank you Sol-Tek and John L!"

"This was my second time putting solar on my personal residence. This time I called Jeff and I was very impressed with his knowledge and with his thoughts on the 'Time of use' programs that PG&E and SCE offer and how that works with your solar system to help boost energy savings!! ie. how it saves you MONEY!!! I would highly recommend Sol-Tek to anyone looking for solar and also for anyone looking to install solar pool heating. They did both for me, and I couldn't be happier."

"For the most part the system has worked great. Few little issues that we’ve had to have the techs come back out and do a quick fix. But we love being able to swim a little earlier and later in the season. And being able to keep the pool warmer. The kids also love the warmer water!"

"Purchased solar thru Sol-Tek in 2022. The experience was great. John L. Made the process so easy and answered all my questions. There was no pressure as I checked out other companies and finally decided to contract with Sol-Tek due to the quality of the product I would be receiving. I have been 100% satisfied and would highly recommend."

"I highly recommend this company! I had solar panels installed. They work amazing! Heats my pool wonderfully. I receive so many compliments on my pool temp. Excellent customer service as well 10+++"

"If you are seeking to go Solar, you gotta go Sol-Tek! Great people from the Sales Dept. to the Installers. Very polite, hard working, friendly and courteous. We have a large garden filled with many types of plants and my wife was concerned about things getting trampled...... the guys were very careful and understanding. We are glad that we went Solar. Sol-Tek was our second choice and we were a bit leery, because the first company ended up jerking us around. Would recommend Sol-Tek to friends and family! We went from spending $600/month on PG&E to a yearly bill of under $1000. We own our Solar which for us is the only thing that made sense."

"We have a Solar Panel system. We did some shopping around with different companies. We wanted a system that we would own because we determined that would give us the best value, the best long-term savings. We chose Sol-Tek because they are a subsidiary of West-Tech Electrical, a company that has been around the SJ Valley for many years. The price quoted and the equipment specified were equivalent to the other quotes we received. The system was installed over 3 days in January 2015. The system has performed flawlessly! Our electrical usage bills went from around $1000 per year before the Solar System down to $60 per year with the system. It is a delight to run the dishwasher, washer & dryer, coffee roaster, electrical garden tools (chain saw, string trimmer, tiller / cultivator, leaf blower) while the sun is shining and seeing that the Solar System is producing more power than we are using. I have had minimal contact with Sol-Tek since the system was installed because everything has worked so well. The installation work was noisy occasionally during the work and we were alerted about that. The quality of the work is excellent. I have been up on the roof to clean dust off the panels and have looked things over. It all looks good!"

"We had Sol-Tek install a solar system for our home a few years ago. It only took them a few days to complete the installation. They explained how it worked, answered my questions, and showed me how to set up my computer access. The best part is when I receive my PG&E bill each month - I always smile! Awesome experience!"

‍

"Sol-tek serviced and cleaned our panels recently, and we were so impressed with their professionalism, customer service, and quality of work! This is a fantastic locally-owned company that we plan to continue using for years to come."

"We had solar installed about four years ago. The guys who installed the system were friendly and clean. I love how the conduits are hidden. Over the years, two panels went bad, and they were replaced in a timely manner. I still recommend the company to anyone who wants solar."

"We purchased a rooftop solar system from Sol-Tek in October of 2015 and couldn't be more pleased with the whole process from start to finish. We were looking for a business that had been in the solar industry for a long time, not a newcomer and Sol-Tek has been doing solar in the Valley for more than 20 years. We wanted a local company. We got a very competitive quote and the best guarantees of the three companies we contacted for bids. There was excellent communication through the whole process and Sol-Tek managed the city permits and inspections. I received a one-on-one tutorial on how to monitor my system via my computer. We haven't hit the summer months yet, but our annual true-up estimate from PG&E right now is zero. I was particularly pleased that I didn't have to endure a high-pressure sales pitch. I got lots of information, without the "you must act now" push."

"We are so happy with the excellent job that Sol-Tek did installing our solar panels. Their crew is very professional and take great care with the details. I can highly recommend them to anyone considering solar."

"We were seeking an affordable way to heat our small pool, so we called Sol-Tek. They gave us an estimate and time frame that worked for us. It took less than one day for them to install the unit on our roof and we were able to enjoy the warmer water almost immediately. The youngest and oldest members of our family can now feel more comfortable in our pool!"

"The best solar company in Fresno and Clovis hands down. I did a lot of research and spoke with many companies but I was impressed from the start with Sol-Tek. They answered all of my questions, were not pushy, educated us and got us on the calendar quickly for our install. The installation was seamless. Highly recommend this solar company!"

They did a great job with great customer service. I’d definitely recommend them for your solar needs.

"We have had such a great experience working with Sol-Tek to install solar panels on our home! Sol-Tek really stands out for having integrity, great pricing, on point communication and answering all of our questions. I recommend them wholeheartedly!"

"Sol-Tek's service was amazing throughout the process. From sales, to scheduling, to installation they were all professional, respectful of the home, and knowledgeable. They installed a large solar system along with 3 batteries that has kept my house from needing to pull from the grid since the install and they also installed a solar pool heating system. I would highly recommend Sol-Tek to anyone considering solar for their home."

I had Sol-Tek remove my solar water heater and move it to another part of my roof. However, they had to work with my contracted roofers and other people. They did an excellent job! Charlene kept in touch with me the entire time and Clayton did excellent work! So happy I had them do the work for me :-)

"Had Sol-Tek do a solar pool heater end of season last year. Just fired it up last week, this system is amazing! Took only one 85 degree day to get the pool from 67 to 77 degrees and 1 week to a steady 80 with 85 degree days. Normally we wouldn’t be swimming until July due to my pool not getting full sun all day. If you are on the fence about a pool heater, do it!"

"Jake and his crew are kind and efficient when on the job. They removed our panels to make way for a new roof. The only negative part of my experience was the gap of time it took to replace the panels and the customer service from the office with respect to payments. All in all, I would recommend Sol-Tek."

"We love working with the Sol-Tek team! Technicians are very courteous. They are engaged, meet their schedule commitments, and keep you informed of changes along the way. When there are hiccups, they respond quickly to address problems and make corrections. Great service at a reasonable cost!"

"Wow,  did 2016 customer appreciation at Pinot's Pallett as a way to say thanks for coming aboard. New app for referrals " get the referral" pays well and rolls out soon. They are at all local home shows working for hugs and handshakes. Great company."

"Just got our first year's true-up bill from PG&E and I have to admit I was kind of surprised...... it was $650 for the year for a household of 5 in a 3k sq ft house on property with a well! That means our previous average of around $450 a month power bill is now $55 a month. Very happy with the system and the support we received from the whole Sol-Tek family during the last year. I would highly recommend sol-tek to anyone looking into solar."

"Our pool solar was acting up making SO MUCH noise it was unbelievable we had the pool company that usually turns it on and off for use in fall and spring look at it last year and they said it was working fine, but oh that noise. So finally I called Sol-Tek they were the ones who installed it so today they came to look at it. Jake was the lead tech and Johnathon his helper. Jake turned the system to run and it was just a minute he already knew what the problem was he had it fixed in minutes. Then he took the time to walk us step by step through turning the system on and off in spring and fall. They were both so nice and very helpful. We truly appreciate their service. I highly recommend them."

"Sol-Tek has been great from the first start! We knew nothing about Solar and John L. and Mona walked us through all of it!  Follow up time was amazingly fast! The only regret I have is that we didn't go with Sol-Tek sooner!!!  It's an A++++ group!"

"We just moved to Clovis and quickly learned we needed solar! Sol-Tek provided us with competitive quotes, worked with our schedule and took care of our needs. We got solar for our home and pool. The crew were great! We would recommend them to anyone looking at solar. Thank you Sol-Tek"

‍

"They are amazing! And super competitive in pricing. We got solar a few years ago and they did a fine job, gave us exactly what we wanted and their customer service is top notch. I would recommend them to my family and friends."

"Sol-Tek representative: John was very prompt with application, explained thoroughly. The installation process was smooth. My nephew also was very satisfied with the service. I highly recommend Sol-Tek"

"We were very leery about getting solar but living in Fresno in an older home we knew it was a must. Tim did a fantastic job explaining the process & putting us at ease. First summer w/ solar & couldn't be happier. Solaredge is a GREAT tool 2 help us be more successful.  Thanks Sol-Tek!!"

“Everyone was more than willing to answer all our questions. Service was quick and nice.”

“Exceptional customer service. Installation crew was professional and commendable -working long hours.”

“Tim was great at explaining the system. Kathy was very nice and accommodating for scheduling. The install team was very respectful and worked well in a house with young kids.”

“ From start to finish, everything was communicated effectively. Overall best price we came across.”

“The team was incredibly responsive and helpful throughout the entire process. Highly recommend!”

“We are from a construction family and were completely impressed with the communication and service provided by Sol-Tek! The staff were polite, timely and informative. The installation team let us know exactly when they were arriving and departing and we did not see one screw or any debris after each day of work. They installed a system that is almost invisible and we are already saving on our utility bill. Sol-Tek’s follow through is amazing and we could not be more happy with our system and their customer service.”

“My wife and I met with several sales reps for solar power system companies. We chose Sol-Tek based on comprehensive assessment of our needs, BBB rating, and price. All the Sol-Tek people were excellent: on schedule when they said they would be here, thorough and clear explaining the work they were doing to install the system and showing us how to operate it.”

“The professionalism, respect, and attitude throughout the installation process were the best I have had in dealing with any company in the past. You could tell these men enjoy their job. I want to thank you for a job well done and I will be sure to let all of my friends know the type of work they will get if they choose Sol-Tek in the future.”

“Please feel free to use me as a reference should your company ever need one – it will be a great one. I had good luck with Westech in the design-build of our building and even had a better experience with the solar side. Thanks again.”

“From start to finish our solar project with Sol-Tek was an easy experience. Everyone we worked with was very knowledgeable. During installation, they were very considerate of our home. What a great crew!”

"I’ve tried other solar companies before, but SOL-TEK stands out. The system is efficient, durable, and the after-sales support is outstanding."

"Best investment ever! SOL-TEK helped our family save on electricity while reducing our carbon footprint. Smooth process and excellent customer service."

“SOL-TEK made switching to solar so easy. My monthly bill dropped significantly, and the installation team was professional from start to finish. Highly recommended!”
