ABC Solar
This is a great honor for ABC Solar as readers voted on their own to name our team the best Solar Company in the South Bay. It will only take moments to understand that we love solar and are ready to design, permit and build your dreams. We know that going solar is a big decision and a lot of information is needed to do it right.

Our Solar Bible 2021 has 300+ pages about ABC Solar workmanship on a variety of roofs and notes on the technology. A survival guide for entrepreneurs seems to be need in updates as the Solar Industry is under attack by the powers at be. For Solar electric systems water pumping is the most efficient.

This is because DC motors are more efficient than AC motors. For solar thermal systems heating water is the most common solar application and by far the most efficient at an estimated 40% conversion efficiency. ABC Solar deigns, permits, supplies and installs this 190 Solarworld grid-tie system in Japan.

ABC Solar has my highest praises I had an issue with my solar panel system that I bought from a different company many years ago. I sent ABC Solar a message asking for an estimate on how much it would cost to fix. Bradley gave me a suggestion to reboot my inverter. He would walk me through it over the phone at no charge. I was very impressed by his knowledge and honesty. I rebooted the inverter and it works. Other companies would probably have tried to rip me off and try to charge me for the service. I can't thank him enough. This kind of standout service and honesty is what I&apos

ABC Solar, did a terrific job! Brad is local to PV (resides here). The work was done very professionally and ahead of schedule. He is currently doing and has done, lots of work in PV and Torrance, but he is not restricted to this area. I highly recommend this solar company, they have a lot of expertise in the solar industry, along with many years of experience.

Brad was and continues to be awesome. They were on-time and patient answering all of our questions. We have had our system for just over ten years and no problems. We highly recommend them whenever we get the chance.

ABC Solar is the best solar company in the South Bay. After having several quotes from various companies we decided to go with ABC Solar and it was the best decision. Their customer service is outstanding and our solar panels are performing perfectly. We are one year into our solar decision and couldn't be happier. Thanks ABC Solar!

Great company. I would definitely recommend them.

ABC Solar installed the PV system on my house in 2016 and I am very happy with it. The owner Brad Bartz is a smart, straightforward, interesting, and somewhat unconventional fellow. He is passionate about solar power and helping remove government and other impediments such as HOA rules that would impede people from being able to utilize PV.

My home has a concrete tile roof which made me a little bit hesitant to put in a PV system, but Brad explained with diagrams how they'd do the installation on a concrete tile roof, and it all worked

Had my system for 3 yrs now. Brad and Mike are the best. Brad still support me when I call. I recommend them to everyone who asks about solar and for them to do their own homework and get multi-bids too. I wanted to give the small local guys a chance as well as the big name guys, but ABC won the bid. Not the cheapest, but not the most expensive. Very reasonable bid, competitive and most of all HONEST. Brad was very patient and explained everything to in simple terms to me and my wife.
He even made the Hero program guy come and explain the tax benefits and financing to us. So I got my system

Brad and Mike installed a system in my new construction and were very flexible with my contractors schedule (my contractor was very slow).

It's been over a year now with my system on and everything is still running smoothly.

I've compared prices and service from all the top companies and decided on ABC Solar and I don't regret it and you won't too.

At the moment my electricity bills are negative and SCE owes me money for excess power production :)

Thanks guys.

Brad and Mike are top notch! I've had my system for awhile and I didn't even purchase it initially from ABC Solar. But over the years, ABC have serviced me with such professionalism that I would recommend them highly. Recently, 1 of my inverters weren't working. Mike called the manufacturer, had another one shipped under warranty and replaced it. I paid $130 for the service call. But then today, a month later, I received a check from ABC Solar for $130 because the manufacturer paid them for the work. NOW THAT'S HONESTY! So rare in business!! I so appreciate them refunding

We are so happy we chose ABC Solar! They attained a local permit and started the work within 2 weeks of my first phone call, and the job was completed a week later. They were so great and considerate every step of the way. The job was completed in early July, and our bills have been about $1/month ever since. It rained for the first time a couple weeks ago, and we had a minor leak in our garage. I let them know and they came out within hours and fixed it even though it was completely unrelated to to the solar installation. No charge to us. Brad Bartz goes above and beyond for his customers.

Best contractor I have ever used. They answered email, texts, phone calls usually within the hour always within a day. They were open to any modifications to their design that I wanted. They were prompt. They were capable. They were knowledgeable. Their employees are friendly and helpful! They did what they said they would do!!

The installation work they did was absolutely first rate. They have been doing this for a long time and it shows. I think ABC solar is the best solar company in southern california. I do not have a single complaint, I have recomended them to all my friends.

After debunking and educating 8 different solar installation companies I was ready to go DIY on my own home solar. One company insisted that I needed twice as much solar as I know I really needed, another half as much. Still another basically called me a fool for not selecting the lease option and letting them take my tax credit. I out-and-out told one I had arranged to buy my own system an $1.82/ watt and they graciously bid $6/watt for an inferior, foreign made system and when I asked them exactly why it was going to cost me $22,000 just for the installation portion they said "All solar

ABC Solar is a South Bay company whose owner, Brad, lives and breathes solar. The installation of our solar power electric system in Rolling Hills Estates was seamless and professional. Office manager Eric was proactive in applying for tax credits and knows his stuff! The permits were all approved with no snags. Supporting a local business is the way to go - I met Brad ten years ago and we got quotes from all over but we made the right decision going with ABC.

Okay, follow me here: I had a company called Independence Power over to do a diagnostics on my Solar System (Installed 2008) recently. The inverter was reading offline and power wasn't being generated. The previous installer, California Solar Engineering, had closed shop and was nowhere to be found. IP did a quick look and insisted that the problem wasn't the inverter (which was reading offline) but the panels. I would need to do a panel by panel diagnostic, removing every panel and testing each and every one. In order to do this I'd need to dole out several thousand dollars just
