Top Ranked Companies


The Good

  • Residential and Commercial Solar Services Available
  • Solar Financing and Payment Options
  • System Monitoring Included with All Commercial Systems

Residential and Commercial Solar Services Available

A1 Solar Power offers solar installation services to residential and commercial customers. The company's turnkey projects begins with a free inspection to help homeowners determine how much they could expect to save each month. California has over 300 days of sun, making it the perfect environment for going solar while saving money on the electric bill and reducing one's carbon footprint. And some states even allow for net metering, which means any solar system that is tied to the power grid will actually run backward when excess energy is generated and this excess energy is able to be sold back to the electric company. In many cases, this will zero out or reduce your monthly utility bill.

Some people may also qualify for the Federal Tax Credit and other rebates and incentives for installing a solar panel system. Additionally, installing a solar system on your home will increase its value and in most cases will help you sell your home more quickly if you ever decide to sell.

Solar Financing and Payment Options

A1 Solar Power offers a variety of payment options for both residential and commercial customers:

  • Outright purchase — An outright purchase is the best, most cost-effective plan to choose for those who are in a position to make such a purchase. When purchasing a solar system, you can use the federal tax credits to cover a percentage of the initial cost. Combine this with your state and local utility incentives and your system will cost you significantly less than you might think. However, you need to act fast because the rebates and incentives are slated to end soon. Another great reason for owning a solar system is that you can lock in your rates for the next several years and as the electric rates increase over time, your solar system will become even more valuable.
  • Leases and power purchase agreements (PPAs) — a lease or PPA option is great for those who don't have much money to put down for a solar purchase. With a lease option, you won't be required to put any money down and you won't have to worry about performing any of the repairs and maintenance either. When you select a lease option, you don't actually own your solar system the solar company does. That means you won't receive any of the rebates or incentives. These will go to the solar company who installed your system. This is how they can afford to provide you with a solar system for no money down. However, with these programs, you will benefit from the reduced monthly rates, which are based on the energy from the system that's on your roof. These rates are fixed and are usually lower than what you are paying your current utility company. It also means you will start saving immediately.
  • Financing — if you choose to finance your new solar system, A1 Solar Power has an in-house finance department that can help match you with the program that best fits your needs and budget. The company's large network of exclusive lenders and private lending pools will provide you with a customized finance plan that other banks and lenders can't. Additionally, there are no hidden requirements at any time. You will also like the fact that A1 Solar Power assigns you a personal account manager who you can work with you one-on-one to give you advice and help you along the way.

System Monitoring Included with All Commercial Systems

A1 Solar Power provides 24/7 solar system monitoring for commercial systems via web-based software and hardware. The solar inverter communicates with A1 Solar Power to relay any errors immediately, which includes live and historical system data, alert notifications and greenhouse gas avoidance numbers. However, this option is not offered to residential customers, which we will talk about in the next section.


The Bad

  • Residential Systems are Self-Monitored
  • Warranty Information Not Detailed
  • Customer Complaints

Residential Systems are Self-Monitored

While A1 Solar Power appears to offer some basic monitoring for a residential solar system, the website clearly states that the homeowner is primarily responsible for the monitoring system. System productivity can be influenced by the weather, climate changes, and other underlying factors and they also ask you to call them should your system experience a complete malfunction. However, A1 Solar Power will alert residential customers if there is a decline in the system's energy production that isn't attributed to the current weather conditions. The company will then help you troubleshoot your system over the phone and will send a contractor team if necessary. As you can see this information is a bit unclear as to exactly what is involved in monitoring your system.

Warranty Information Not Detailed

A1 Solar Power mentions a 10-year warranty on the installation of your system; however, they don't say what the manufacturer's warranty is or even a range of what they might be depending on the what particular manufacturers provide. Most solar companies proudly display all the warranties provided by their company and their manufacturers. But since A1 Solar Power does not, you will have to confirm with them exactly what warranties are being supplied for your particular system and then make sure that information is clearly stated in the contract before you sign it.

Customer Complaints

We also performed an extensive search of the online public forums and found an unbelievable number of complaints. Here are some of the complaints we found:

  • Their checks bounce
  • Salespeople seriously misleading potential customers to get a sale
  • Not fixing leaking roofing issues
  • Referrals not being paid as promised
  • Many, many complaints about unwanted solicitation phone calls, robocalls, and abusive telemarketing practices
  • Customers being charged for a system that was never installed
  • Several reports of customer solar systems being installed incorrectly and no one from A1 bothering to follow up or returning the customers calls
  • Insulting high-pressure salespeople
  • Higher than quoted electric bills

The Bottom Line

Installing solar cells is a great option for people who want to save money on their electric bill, increase the value of their home and reduce their carbon footprint on the environment. However, installing a solar energy system on your home is a huge undertaking. Therefore, you really need to make sure you thoroughly understand the process and the payment or leasing options, before you make a 10- 15- or 25-year commitment. Most solar companies are more than happy to educate you and help you through the entire process and most of them also take care of everything for you from the consultation to the rebate paperwork to the installation, permitting and inspections. But knowing how everything is supposed to work will help prevent you from being taken advantage of from any given company.

Unfortunately, we are unable to give A1 Solar Power a recommendation good or bad due to the high number of complaints on the online public forums. If you decide to consider A1 as your solar provider, spend a little extra time gathering as many facts and details as possible (including reading verified A1 Solar Power reviews) to see if the company is a good fit for you and your particular solar situation.

Joseph Di Chiacchio Agoura Hills, CA

From the moment the salesperson left to the moment the system was installed, I found each person with whom I met to be professional, knowledgeable and extremely courteous. After about a year I noticed an odd discoloration on one of the panels. Fearing a failed solar cell, I called A-1. They were responsive immediately. A team was sent over within 24 hours and it was determined that the discoloration was created by a large birds' reminder that they fly overhead. Evidently, the washing away over time had left the odd stain. They cleaned the stain and the system looks pristine . I hold A-1 in very high regard.

I chose A-1 based on the sales presentation which was thorough and included photos and drawings of the whole installation process. The installation crew was equally impressive as they paused to answer questions from the roof. Installation was enabled by a very responsive city staff with timely permit approval and inspection. The only glitch involved the router which allows me to monitor output on my computer--the problem seemed to be in the construction of our old house which the technician was able to circumvent. 40 inches of rain fully tested the installation. We are very pleased with the results!

A1 Solar customer service was the worst!. They wrote in my contract that If I needed a new roof, they would come and remove the panels and put them back on upon completion of the new roof - FREE O CHARGE within 10 years of solar installation. There office had closed in Petaluma with no new phone numbers. I finally contacted their main office, and they promised to have someone contact me to have the panels removed. No one called even after I contacted them again and again. I learned that they sub- contract many of the jobs out. Finally, I got local Solar company to do the work. Although it cost almost $3000. for removal and re-installation, the job was done professionally. I am now using Simply Solar to monitor my system. BEWARE OF A1 SOLAR. They make many promises but after the job is completed, you are on your own

Had the system installed three years ago. It has been great! In the summer my electric bill went from $350 to $450 without using much A/C to under $50 and we use the A/C all the time now.

Good luck to anyone that gets in bed with this company because you are sure to get *^#@!+, if anything goes wrong . For example, let's just say the integrity of your roof is like TOTALLY compromised due to A-1's un-professionals having forced-drilled (not pre-drilled) a healthy number of 5 inch lag screws into your roof, causing the roof to leak every time it rains. Interior damage? You betcha. But will A-1 step-up-to-the-plate and honor their guarantees or warranties? Ha! Ha! Ha! We're still waiting, and we have been in this "waiting game" for months now. Our roof still leaks (Thank God! It's not raining right now.) And all of the interior damage to our home has never-- EVER--been addressed by A-1. Do your research. A-1 is known for its lack of commitment.

This company took 5 months to complete the installation even though their contract language stated "Time to complete on-site construction activities is one to two weeks for a typical residential system". They presented me with one layout -that I signed off on - and then installed a different layout for the system. They were very slow to respond to my inquiries and often did not answer all the questions I had. Now - 6 months after the completion of the project 5 of my panels are not producing energy like they should. My system has dropped by 33% in productivity. (15% of that could be attributed to shorter daylight hours. They sent out an engineer who discovered the problem - and he was told to tell me they will get back to me. That was Tuesday of this week - It is now Saturday no one called me to follow up on this I have no confidence in this company. I understand they are now doing business under a new name "Colby" solar. I hope the name change does not somehow negate the warranty that I have. I have paid nearly $50,000 for 34 panels and I am very disappointed in the performance of the system.

Said they would monitor and maintain system for 25 years. They didn’t even do 1 year! Our true-up bill 1st year was approx $800 which we were expecting but the next year was approximately $2000. When we tried to contact A1 to see what was wrong, all we got was answering machines and never got a call back! We were told to call canopy sales and got no where there, we spent $40,000 on this system and feel totally had! Wish we could file a legal grievance against these people! Any advice on how to track these people down, let us know!

I have made five calls to A1 Solar, left a message with the operator and my telephone number for a call back from the support department. None ever received. A call today resulted in continued disconnection with the operator and when I pressed button #2 as an existing customer I kept getting a dial tone. The Internet states their Van Nuys office is closed. It appears they may be out of business?

We had our Solar put in 2013 and have had nothing but problems, poor customer service and our solar had not been working for a month and half and they will not return phone calls, sent letters and sent letters to the CSLB, we have 28 panels and cost us for 41.000.00. It looks like they are under review with the CSLB
