  I have reviewed the response made by the business in reference to complaint ID ********, and find that this resolution would be satisfactory to me. If they say this $800 fee they tried to get from us is no longer there because of this then we are 100% good. I will consider this complaint resolved.

  I'm not sure why we did not get a notification on this complaint but as far as I can tell this job is complete with no outstanding issues.

   My original system has 36 solar panels. My system is reporting 34 panels, and 2 inverters are basically producing nothing each day. So yes, my system is PARTIALLY working, but I'm more than 10 percent less than it should be.  They had a case open to replace the remaining 24 inverters but that was closed after sunpower declared bankruptcy.

  As for the non export system, I was completely misled by repeated incorrect statements from the salesperson.

  I have attached numerous email correspondence where he talks about production and then says NOT to get a battery. I also have 2 different phone recordings where he explains that as long as the total production between BOTH systems doesn't exceed the initial systems limit, it would export to the grid. Kept talking about the loophole and that's why the contract said 0 kWh.

  the same time (April 2024), I began receiving emails from ****** ******* about increasing the size of my solar system without losing my net metering status. Their emails claimed that it was a limited time offer, despite this offer still being possible today. It felt shady. In any case I pursued this option. I met with my original salesperson, David **** who explained that it was a secondary system. On multiple emails, in person visits and phone calls (of which I have documented), he explained that the new system could EXPORT to the grid, as long as I was not exporting more than my current solar allowed for (around 10 kWh in my case). After the system was installed, I found out that this was NOT the case, and that I purchased way too many panels since I would not be able to use the power being generated by the new panels.
  
  After getting supervisors installed, they stopped responding to my questions about both issues.

  Hello thank you for reaching out about this 

  
  

  
  

  
  

  We have already had extensive back and forth with this customer. His defective micro inverters were replaced by sunpower and the system is functioning. He does have recourse with the solar panel manufacturer ****** If he has a bad panel and with ******* for the micro inverters If there is a problem in the future but for now the system is working. There is not a warranty issue here as the system is working.

  
  

  
  

  As for the non-export system the customer purchased. It does not export to the grid. It's literally called a "non export system", calls out zero export on the order form and there is a detailed explanation on his contract regarding this which he initialed specifically explaining this.  We did offer him a discount on a battery at cost to help him capture more electricity which is more than reasonable but he's pressing for more.  There's not much more to discuss here.

  It is illegal in California to record someone without their explicit consent.

  
  

  Nothing in those emails indicated that a non export system will export.

   

  The system is not under producing original estimated.  You may contact the manufacturer.

  Due to the illegal recordings have referred this matter to legal counsel and will no longer correspond here.

  - Absolutely the worst customer service!!!Representatives never return calls and fail to give accurate updates on Solar Panel projects. Search out other Solar Panel companies first before selecting Semper Solaris. In addition Semper Solaris took around a month to return my call call for a problem I had in my system which resulted in my electric bill doubling!!! Please look at all reviews before making a decision on this company! Wish I had went with another company. After spending close to $60,000!! Seeking compensation.

  This customer has a single micro inverter that is defective from the manufacturer enphase.  This means a single panel on his system is not functioning.  The replacement part has been provided to the customer by the manufacturer and we are in the process of scheduling the installation.  A single panel malfunctioning did not result in this customer's electric bill doubling.

  April 25th, 2025 i wrote Semper Solaris CEO to notify him that his company had failed to meet my solar requirements and promises from the sale team. I worked my way through several levels of customer service where they admit confusion and fault, they did try to offer solutions but not at the level that was promised to me. I still do not have backup power in the event of an outage.

  I have attached the portion of my contract that states that Semper Solaris will repair broken parts UNDER WARRANTY WHEN SUPPLIED BY THE MANUFACTURER. The mfgr. has a 25 year warranty. 
  I asked the salesman if the warranty covered labor also. He said it did. I had asked the salesman (Kevin Hatfield) to be sure that was in the contract. 
  If you look at the fact that they have been here no lees than 10 times to replace 6 Optimizers over 5 years WITHOUT CHARGING FOR WARRANTY LABOR. WHY NOW? What has changed? My contract hasn’t. If they felt they could’ve been charging me previously, they would have.

  Thank you

  Our contract does not say we will provide work for free.  There is a charge for this repair.  The material is supplied for free from the manufacturer under warranty.  The homeowner may also contact the manufacturer directly for replacement.

  

  Business Response

  Thank you 

  Our agreement does not say that we will perform this service for free.  In the past sometimes we have done certain services at no charge but we are not opting to do so in this case.  The homeowner will either need to pay for our labor or we can refer this matter to the manufacturer and they can take care of it themselves. 

   

  Please let us know when you get a chance if you would like to cover our labor costs or if you would like us to redirect you to the manufacturer for them to service. 

   

  Thank you

  So SS has offered to do THIS replacement of the failed Optimizer at no charge THIS TIME BUT WILL CHARGE LABOR IN THE FUTURE. This is not what the contract says.
  They say we are at an impasse and I should be call the mfgr. MY CONTRACT IS FIRST WITH SS, not the mfgr. SS sold and installed this system. They are in the contract as CONTRACTOR and responsible to abide by the CONTRACT. The mfgr. is doing their part by supplying the optimizer UNDER WARRANTY. 
  Is the BBB going to do anything else?

  Closed on a house built 2017 with existing solar panels and equipment installed by Semper Solaris. Solar Transfer Information completed and accepted by Semper Solaris 5/30/2024.While solar production appeared to be functioning, no communication with equipment (SunPower) could be established. Warranty claim submitted with/through Semper Solaris 06/17/2024. After many requests (multiple case numbers), Semper Solaris sent out various technicians and determined a communication module (MySunPower) needed to be replaced. As of 11/4/2024, replacement time was given as 2-3 weeks. Part apparently never came in from **********. Following multiple attempts more with Semper Solaris, MySunPower and later with ********************, no resolution to warranty claim has occurred. It has been over 325 days since my warranty claim was submitted with no resolution and no meaningful contact by Semper Solaris to resolve my solar communication issue. The problem they state is with the bankruptcy with ********** and part(s) are not available.Semper Solaris should stand by the products that they selected and installed and assure they function as intended.I even identified the part (new) on **** (<$100) and offered to purchase it, if they would install. They said someone would contact me with a quote, which never took place.Short of giving up totally on the installed equipment and contacting another company to install, I as the consumer am at a total loss as to how to get the warranty claim honored at any sort of reasonable cost.I request that Semper Solaris correct/repair my communication issue, so that I can know how or if my solar system is functioning as designed.

  Semper Solaris is lying.  I provided the electric usage information before I signed the contract.  I was told by my sales *** that there was plenty of money still in the fund when I signed the contract.  Semper Solaris never submitted the rebate when I gave them the usage information back in November ************************* again for the same information this past April.  I would never of signed the contract without the guarantee of the $5K rebate.  I have emails with the proposal that includes the rebate and the email of me sending them the usage information.  Semper Solaris can pay me the $5K and get it back if and/or when they want to resubmit the rebate.  Semper Solaris lied to me when they told me I would get a rebate.  If they do not want to pay me the $5K, they can come me take off the Solar panels and Battery.  If they are unwilling to do either, I will be contacting the CA ****************** ****, Tesla, the finance company, The County of ********* and the Star of CA to lodge formal complaints about how Semper Solaris is getting people to agree to purchase their product with a promise of a sizable battery rebate that never happens.  This seems to be something all of these entities would be interested in.ted the rebate info so he could process the rebate himself. I replied back stating that I sent him the info back in November and I will resend the same email back to him. After this interaction with ****** through text, I reached out to Semper Solaris customer service...which is non existent. After several attempts by phone and email, a manager named **** ***** reached out to me vial phone and text on 4/10/25. He reassured me that he would get to the bottom of this and claimed that he would call me back. He also told me that he has ************************************************ He also reassured me that he would always return calls and texts...I have not heard back from **** since our first conversation.If Semper Solaris is unwilling to refund the $5000 they promised me at the time I signed the contract, I would like them to come and remove the Solar and backup battery system they installed as I would never of purchased this system without the $5000 rebate.

  Required timed homeowner electric use information was received too late for the application window at the end of last year.  Another window will open this year and we will apply at that time.

  

  Business Response

  Good afternoon 

   

  We will be able to apply for the rebate when it opens again this year.  We are not lying, SGIP put its program on hold for part of the year and changed the application process and the specific information required (electrical use information).  If the homeowner wishes to report the matter to various authorities that is okay with us as we have done nothing wrong.

  Home Solar Project with 2 Batteries for storage. We signed in Nov 2023, the project was supposed to be completed by March 2024. Today in April 2025 it is only 90% complete. The incomplete items include the **** incentives for the 2 batteries. There is some trenching work where the wiring went through some concrete (driveway), which they haven't filled up. When we signed the contract it was supposed to be a complete project, now they say the trenching coverage is our problem. I have already paid for the system.I have asked to someone senior in the company preferable the CEO, but I can only communicate with **************** Agents.The work they did was good and works quite well but they refuse to finish the work.

  

  Business Response

  Date: 05/13/2025

  Hello thank you for reaching out about this.

   

  The Battery incentives must be applied for one at a time.  First one than the other.  We have explained this to the homeowner multiple times and sent them the appropriate paperwork but they have yet to sign it insisting that we must apply for both at the same time which is not permitted under the rules.  They're welcome to apply on their own if they prefer. 

   

  As for the trench this is not covered under the scope of work for the project.  This has also been explained many times.  We did offer to defray part of the cost but the homeowner is not satisfied.

  Dear BBB and Semper Solaris:

  I hope this finds you well!

  While I appreciate that Semper Solaris has located a replacement micro-inverter to address the issue with my solar system, I must reserve judgment on the resolution of this matter until the unit is installed and my system is fully operational. Given the extended delay of over 18 months, I remain cautious and will withhold satisfaction until the repair is successfully completed and verified.

  Sincerely,

  **** *********

  anufacturer of our solar system, SunPower, and having us do their work by constantly calling SunPower for updates on when this would be resolved. It took until late March, 2024, before our cell kit was upgraded to 5G. Now that we had communication back with our solar system, we could see via a SunPower Apple iPhone app that one of our solar panels was NOT working at all. Again, after much time spent on the telephone with various representatives of Semper Solaris and SunPower, and a Semper Solaris field technician inspecting the system on our roof, it was determined that the cause of the one solar panel NOT working was due to a Micro Inverter (MI) NOT working. Semper Solaris never could get us a new MI. One reason was SunPower went bankrupt during this time frame. Bottom line, we have a 25-year warranty on our solar system, but Semper Solaris has stopped answering our emails and phone calls. We only have you, BBB, to get them to honor their warranty without us having to go to court.

  I am experiencing ongoing issues with our solar inverter, which has been failing multiple times a day and requires a physical reset each time. It's only been 1.5 years since installation! We were informed that it's common for inverters to fail, but given that we invested $30,000 in solar batteries, an inverter, and HVAC from your company, we are extremely disappointed with the lack of urgency to address this matter. Our electricity bills continue to rise due to these ongoing issues, and when we attempted to reach customer service, our call was disconnected when we requested to speak with a manager. This is particularly disheartening coming from a veteran-owned company that claims to prioritize quality. Based on our experience, I cannot recommend your services to anyone. It has taken months to get a technician to evaluate our system, and now we have been told we must wait even longer for "monitoring." This situation is completely unacceptable.

  We were at this customer's home a couple days ago troubleshooting the inverter with the manufacturer.  The manufacturer has requested observe the inverter remotely for a few days and will get back to us next week.
