Talk to Devon from Mona Lee Everything went really smoothly. He answered all my questions to my satisfaction. He went over my different options for lease (different rates), purchase or finance. Can't wait to get my project started and installed. Feels good to know that I'm not going to be tied to Edison and we will have a home backup system. He also helped me to confirm my decision in near future to buy a Tesla model X. He may be getting one too! LoL read more

IMPORTANT NOTE: This company was formerly known as MONALEE and has recently rebranded to ARTEMIS. Same company, same people. Please read before signing with either. We signed our contract in December 2024 and now, 15 months later, the project is still not complete. I sent over 20 emails, made 50+ text messages, and countless calls just to keep things moving. I have no doubt the project would have been forgotten entirely if I didn't constantly push. I had to help the installer troubleshoot a fire alarm issue they couldn't solve. I had to reinstall my own roof rack that was left sitting on my property after installation. I had to remind them of items IN OUR SIGNED CONTRACT that were never going to be delivered otherwise. Every response when I raise a concern is the same: "We're sorry for the delays, we're working through it." Nothing ever changes. There is NO accountability and NO follow-through. The panels work and I believe in solar - but this company CANNOT be trusted to deliver what they promise without you managing every single step yourself. Look elsewhere. read more

RED FLAG WARNING! It seems clear to me this is a private equity owned company, not interested in actual service and customer satisfaction. THEY DO NOT PAY THEIR SUBCONTRACTORS! This is terrible for homeowners because subcontractors can place a lien on YOUR HOME. You will suffer for their disregard for subcontractors that they hire. My husband- a licensed contractor - did $10K worth of work for them, a sum and estimate they agreed to and have not paid him after months of attempts to receive payment! read more

Worst experience I ever had with a company. Told me in October 2024 that my system should be complete by the end of 2024. It took until July 2025 before my system was online. Mona Lee never explained how to use system of gave me any instructions. They sent an email on how to turn system on after I called and complained. This company is out of California and sub contracts all their work out. Use local solar companies and you will be better off. read more

the footings from their solar install is causing leaking into our home across the install into multiple rooms. we had a roofer come out who said the footings installed are not done right for our style of roof. Mona Lee will not fix it. they sent an "installer" out who tried added sealants everywhere to no avail. we are sick of having a wet swampy leaky home. what can i do to make them fix this mistake. they are telling me i have to let them do it to be covered by warranty, but they aren't fixing it! read more

Installing a residential solar system is a complex, technical process that demands careful project management. Customers should be aware that there are multiple milestones involved, and timelines can be extended due to factors like utility company approvals and local building inspections. In my case, Monalee's team--from sales to project management to installation and final approval--delivered an excellent experience throughout. read more

Mona Lee - Monalee residential solar w/ EG4 battery - Solar Installation Near Me - Sacramento, California

And it took 3 months for you to respond....... No I am sorry from anyone, ignored request for some type of credit or compensation. We had to call national grid, the town code officer, the state regulators, the initial finance company, and beg them to call Mona Lee . Thanks to all of their calls and help the system is now activated on may 15th 2025 182 days from install to activation. Not a word since.... No check to see if it is working, no apologies, no credit Horrible company. Run from them. read more

We signed a contract with and made payment $7,090 with Monalee for the solar panels installation on July 2025. Till September 2025, no any update. After many emails, they said they could not promise completion in the required time frame, we requested the project be cancelled, they agreed to a full refund, the refund would be made at the end of October 2025. However, that never happened. As of today January 20, 2026, after we emailed and called them numerous times, still no refund, no emails no phone calls. I've noticed there are many customers are experiencing the same as us, many complaints are on BBB, Raddit.. read more

I would give zero stars if I could. It's been a full year since we started our project, we've paid the entire price and not only have we not got a working battery yet, they've disabled our solar and we've been without solar power for half a year because of them. run as fast as you can. read more

They don't return phone calls! I paid my deposit for over $10500.00 over 6 weeks ago and still haven't called or text me!!!

This has been the worst experience I've ever had installing a solar system. They are utterly disorganized and unprofessional. They use subcontractors, which makes everything incredibly confusing. They even failed the inspection but submitted paperwork to the loan company to get paid for the work that hadn't been completed. I wanted a solar battery, but after this experience, I will never be doing business with them again. I have SunRun on my other properties, but Mona Lee offered such a great deal that I went with it. However, I would rather have professional service, organization, and reliability than to pay less. I recommend going with SunRun or another company. read more

This was a complete disaster . They absolutely screwed us . To date the service is not complete. The have 11 missed appts including missing the county inspector two times then after install they sent another installer because they themselves said it wasn't right They contract installers they don't have employees that do that. Absolute nightmare read more

Monalee installed a solar battery for us in April 2025. When we lost power last month we found the battery is not working. They have not come back and keep canceling appointments set for a technician to come out. They also promised to send a check for a referral and a credit owed us which never arrived. Was supposed to be on the mail since June 2025. Been talking to Katherine, Carissa and Jamie. All calls and emails are being ignored now. Horrible customer service. read more

Extremely bad. All reviews are fake which tells you how great they are. Multiple cancellation for installation once they get you sign the contract. My installation was pretty badly configured. No one picks on their customer support. Its been 3 months I have been trying to get in touch with from support but no response at all. I paid $72000 for solar and its not working anymore. Now I pay PGE and loan payments as well. They are scam. They will be on call if you are a new customer but not once they install. read more

This company started with great promise. It's been 8 months since the installation and I haven't heard a word on activating the system. Another system that was installed almost a year ago is faulty. I'm receiving no response. read more

So here is an update on my Tesla Power Wall project with Monalee. You can read my original review from 08/01/24 to get the pertinent background information. Yesterday was Monday December 16, 2024, and Monalee finally sent out a technician to make the necessary revisions in order to pass the inspection. He had to install 100 amp breakers in both the gateway and the subpanel, and affix safety stickers on the main panel. Later in the day, the city inspector came and signed off on the project. Finally, 10 days short of 5 months after the failed inspection, the project passed inspection. Let me fill you in on what transpired between August 1 and December 16. I mentioned in my previous review that I was being ghosted by Monalee, even after the initial inspection failed. After reaching out to and being ghosted by Chayse and Brittany shortly after the failed inspection in May, I also texted Andrew, who was my initial point of contact and someone who was always responsive in the past. Again, crickets. I had sent detailed information and documentation from the city inspector about the failed inspection, and the steps that were needed to rectify the situation. A few more weeks went by, and I decided to email Keith, whose title is "customer success manager". That seemed to get some results, as shortly afterwards, I received an email from Jimmy, who is from the title and licensing department. At first, Jimmy was responsive, and assured me that Monalee was working towards taking the necessary steps to pass the inspection. He didn't however, seem to have any of the information about the failed inspection that I had sent Chayse, Brittany and Andrew within the past 2 months. In this way, there seemed to be some sort of disconnect in the chain of communication between Monalee representatives. However, after a few weeks of back and forth emails, Jimmy also fell off the face of the earth. By this time, October was upon us. I emailed Keith again, and suddenly I received an email from Jun Lopez, whose title is inspection specialist. Jun seemed to have reviewed all the pertinent email chain going back to May and profusely apologized for the delays, and assured me that the revisions were being submitted to the city for approval. Jun was responsive for a couple of weeks, then also stopped responding. Finally, I received an email from Cameron White, whose title is field operations manager, and he finally confirmed on Thursday December 12 that the revisions and final inspection were scheduled on Monday December 16. If you have been following along, I think you sense a pattern here. Needless to say, I think it's fair to say that their communication skills and customer service leave a lot to be desired. I'm not sure if the issue is that they have a lot of turnover, which leads to people disappearing along with a sudden lack of communication, or if they engage in a system of just kicking you down the road from one person to the next. However, I have raised their star rating from 1 up to about a 2.5 (I'll round it up to 3). This is based on their competitive price, along with the fact that I'm willing to give them the benefit of the doubt and hopefully my case is more of an outlier than the norm. Everything up until the inspection was A+. But as much as I hate to say, their customer service after the failed inspection was nothing short of atrocious. The good news is, my Power Wall seems to working well, which of course is the first and foremost. I'll be back with another update if I run into issues and there is anything worth mentioning. That could work both ways, incidentally, so if you're reading this Monalee, don't forget that taking care of your existing customers can sometimes be more important than trying to attract new ones. read more

The Great Disappearance Act Signed up with Mona Lee and everyone was very responsive. The quickly sent someone out to me house for a site visit. The person said I would hear back from them in 3 to 5 business days with an update. I received a bunch of automated emails letting me know they were working on it and to be patient. After two weeks I called because my roofer was concerned that no one had contacted them from Mona Lee. At that time they said that someone would get back to me but no one did. I followed up with the original sales person and he got back to me the next day to let me that they could not do my house because it is a post and beam house and the engineering seemed too complicated for them. Mind you, my house was always a post and beam house and I told them that. And the guy on the site visit saw that too. I wonder if they ever planned to say anything if I didn't follow up. So they cancelled my project and I asked that the $1,000 deposit they requested prior to the site visit be credited back to my credit card. I was told by the salesman that someone would reach out to me with details of when the funds would be returned. No one reached out to me. I contacted the salesman again to let him know that no one had gotten back to me. He said he would call them after Labor Day weekend and sent me an email that someone would reach out to me that week. After 2 weeks, I never heard from anyone and contacted the fraud division of my credit card company to seek a refund on my behalf. They were able to get my money back after Mona Lee never got back to them either. At this point, I feel like I dodged a bullet. I ended up losing my back-up bid and paying more to get the work done prior to the expiration of the tax credits on 12-31 but I feel like my local company will not leave me hanging and chasing them the way Mona Lee did. read more

0 Star - Avoid at All Costs Don't get ripped off I deeply regret ever signing a contract with Mona Lee Inc. On November 10, 2024, I hired and paid them $60,000 to install a 24kW roof-mounted solar system on my home -- including 60 LONGi 400W panels, 3 Tesla inverters, and all the necessary electrical upgrades. The system was supposed to come with a 25-year warranty, and the inverters were warrantied for 12.5 years. Fast forward to March 2025: Mona Lee told me the installation was complete and demanded final payment. But when I checked the system performance through the Tesla app, it was clearly underproducing. We'd done our homework, and it was obvious something was wrong -- especially compared to our neighbors' much smaller systems that were generating far more power. At first, Mona Lee insisted there was no issue, but after we pushed back with data, they finally admitted one of the three inverters wasn't working. Tesla eventually fixed it remotely, and the system started working properly -- for about 60 days. Then, in late May, the system performance dropped off a cliff -- down to 60% production. Once again, we reached out to Mona Lee. This time they shoved us toward Tesla's app-based support, which is nothing but frustrating, automated AI troubleshooting. After wasting time with that, we asked for real help and got tossed back and forth between Tesla and Mona Lee. From May 30 onward, it's been a circus of excuses and empty promises. I was told a tech would be sent "ASAP." Then they told me it would be "2-3 days." Then "we're escalating the issue." Then... nothing. As of July, no technician has ever come, and my system -- a massive, expensive investment -- has now been mostly non-functional for nearly two months. I've sent multiple follow-up emails, including a registered letter to their corporate office. All of it has been ignored. Bottom line: Mona Lee Inc. takes your money, installs faulty equipment, and disappears the moment there's a problem. They blame Tesla, deflect responsibility, and offer zero accountability for the system they designed, installed, and guaranteed. My system worked for less than 20% of the time it's been installed, and I've been completely abandoned. If you value your time, money, or sanity, do not do business with Mona Lee Inc. I wouldn't trust them to install a lightbulb, let alone a solar system. read more

Got a great set of quotes for various Black Friday deal options and this was by far the best deal across 4-5 companies I talked to. Only one company matched them. (Think about just net metering , various types of credits possible for your state too, example for MA there's RAC PROGRAM, think battery vs no battery, long term warranty vs base vs standard warranty) depending on discount tiers. Right from the start to end of contract signing there was a lot of attention and transparency in the conversations. What's great is you're more equipped to use the design ideas from all folks to use for Monalee as they take note for that step (as a detailed one for later) I highly recommend talking to Monalee and make your own assessment. Email me for a referral at any time! read more

Horrible customer service. No one ever calls you back. Takes forever to even get the system on. Its been 4 months & still have no working system. They have been paid in full for the last 3 months. Spoke to numerous people & no one takes responsibility & get the same speech from all of them " Someone will call you back" As of yet No body has called me back, just the stupid automated emails are even correct read more

Excellent customer experience. Honest upfront, onetime and accurate. Easy to get in touch with and not rob callers. Overall great service so far and looking forward to a smooth install read more

Scam. Paid in full for my battery + solar set up (29k in cash before rebates/gov incentives). The 3rd party they sent out to install had no idea what they were doing, couldn't explain how the system worked without looking confused. The set up looks terrible and not clean... there are actual metal pipes running down the length of my roof to the powerwall. It wasn't bringing in many Kws and now it doesn't even work. Getting in touch with anyone beyond the initial "we're sorry" customer service people, who are actually very nice, is impossible. Either no one has any power or they don't care to follow through. Since getting the system that their engineers swore up and down would cover our bill, we've paid over 1300 in PG&E costs and it hasn't even been a year. Stay away from these scam artists. read more

From start to finish, the experience with Monalee's representative and installation team was outstanding. Derek, the sales representative, reached out promptly, took the time to understand my needs, and provided the best options available. I needed two batteries installed and chose the EG4 models based on his recommendation. The entire process was impressively fast--completed in just about 1.5 months. The installation crew went above and beyond. I'm very glad I chose this company. read more

Mona Lee - 2 EG4 batteries and 18k box - Solar Installation Near Me - Sacramento, California

excellent experience with Mona Lee. The price was spot on about what I expected for similar service. I needed a solar installer that was willing to work with a condo, and not even Tesla would service our location. After a bit of research, I went with Mona Lee and they were able to get our site mapped automatically through a drone, and a few months later they came back with a proposed engineering plan and cost structure. A fair bit of advice to anyone living in California: definitely go with a combo solar and battery purchase. After Net Energy Metering 3.0 passed, just getting solar would not be worth it any longer. read more

I finally gave in to getting solar due to APS cost rising. Dealing with the rep was very pleasant and knowledgeable. As for the site survey, it went without any issues. Richard was very easy to talk with and I learned a lot more about solar and the installation process. Richard did an excellent job in surveying both the inside and outside of my house. Adding the drone survey was icing on the top. I would recommend Mona Lee to friends, family and my neighbors. read more

Dear Monolee Team, I am writing to express my sincere appreciation for the exceptional workmanship demonstrated by your San Diego installation crew. Despite the challenges posed by my steep roof, they persevered and delivered outstanding results. The solar panel installation is not only functional but also visually appealing. The battery panel, in particular, is a masterpiece of professionalism. I am thrilled with the final product and grateful for the crew's dedication to getting the job done. Today, January 9,2025, i just got word power will be turned on!! Requested information and the next day approved the installation, and in 34 days, the power is turned on! Application to an approved loan to POWER ON! OUTSTANDING! Please extend my thanks to the entire San Diego installation team. I am delighted to recommend Monolee to anyone seeking top-notch solar panel installation services. Sincerely, Godwin read more

We have had our solar since July and it has never worked consistently. Several calls and emails have gone unanswered in a timely manner.every time you call you get a recorded message .our problems have yet to be resolved read more

TERRIBLE company. Applied on line and was approved by Monalee and Goodleap their finance company. A week after both approvals I was notified that finance was declined due to an address error. My Monalee rep and myself tried to correct the error but could not. Another week lated I was "cancelled" because I live in a manufactured home. Over a year ago I had applied to Monalee and was approved and they did the inspection with photos of my home. When I applied this time I had to confirm the Goodle aerial photos of my home. Sunrun Solar asks up front if your home is a manufactured home and they as a company don't do manufactured homes. They have a policy but they cover it in advance. Monalee KNEW from their records and inspection I had a manufactured home. Monalee and Goodleap approved me in writing. The company is unprofessional and I would not recommend them. read more

Good luck- they set you up with a contract then disappears. 15 days of calls and emails... Crickets. Assuming we're not gonna make the year end deadline, so they are costing us thousands and don't care one bit read more

Derek Edwards from Monalee was so great to work with! Knew his stuff, pointed me in the right direction, and didnt seem pushy at all

Purchased a Tesla Gen. 3 Powerwall from Mona Lee. Powerwall 3 has a built in Inverter to replace the aging inverter in my system. Sub-contractor came to do the site survey, no Q & A session; different sub-contractor did the install, no Q & A. Communication with the company is garbage! 10 people texting you but no one takes your calls! Hot garbage. My systems was poorly designed and now I am having issues. Will follow up to see if they get resolved. They were the cheapest quote... But you will pay on the backend!!! read more

I told him that I would have to check with other companies to compare and he was ok with it. Very honest and informative. Will recommended to friends about thi company. read more

I picked Mona Lee as I liked their no pressure sales team and ease of doing business. I compared prices with another company and they were hands down the better deal. The site inspector was great and the details of the site plan were frankly amazing. They used a drone and created a detailed map of my property, the roof, my existing solar system, etc. The plans they developed showed clearly where my existing system components were and where they would be installing the new system. My new system was being added as a non-export system, meaning no power goes back on the grid. We did this because that would have changed my NEM 2.0 status of my existing system to NEM 3.0, which frankly sucks. This is a new option and Mona Lee handled it well. The panels and invert got delivered to my house the day before the install, which was schedule very quickly after my roof was redone and my old system installed back. I helped unload everything as it was just one guy and it would have been a lot of work for a single person. The installers that came then next day were great. Super friendly, professional, and did amazing work. They finished in around 8 hours and got me all setup monitoring my new system after the normal "system updating" process. Tesla makes a pretty slick app for monitoring. I appreciated how well they cleaned up and painted the conduits to match my house color. Over excellent experience and I highly recommend Mona Lee. read more

Do not consider this company. Deceiving salesman, who overpromised. They outsource terrible installers, who damaged our roof, and did a terrible job to remedy (took a year). All of their original contacts quit during the 1st year. It was the worse 1 year stretch of agony for us. Nails, cut metal debris, silicon tub tips, conduit were left all over our roof. Torn shingles and broken stucco to our roof and home exterior wall. They then have the audacity to send multiple demands for the final payment. Their request for payment kept coming throughout the entire process and asked us to "just ignore the system generated " collection attempts, yet threatens to place a lien on our home. Meanwhile, they can't even provide a remedy to repair our damaged roof. This company also scheduled 4 inspections (4 different days) with our city, which we took days off, while they pulled no-shows for. It hasn't even been a month since the inspection and our final payment the inverter wifi broke. We reached out to the and guess what? Yep! They completely disappeared and blocked all communication with us. We are also blocked from all of their social medias. Be very aware who you are dealing with. This isn't the company you want any association with and it's only a matter of time they hit the news. As I mentioned, this matter took almost a year and it's because of the lengthy correspondence I need time to compile to submit to all venues to make this company known, but rest assured that it will be done. Consumers beware! read more

Everything about this process is so much better than other solar companies. No pressure, no long winded sales calls, just answers to my questions and help with what comes next.

What can I say about Mona Lee, except Mona Fantastic, if you ever have any questions, they are a phone call any or by email, always willing to help and the install grew where all wonderful, took a day and 1/2 to install and can't wait to start saving money once my PGE is off and the system looks great also, they also beat any local Solor company by thousands, the time to go solar is now, Give Mona lee a Call. read more

I looked at several companies. This is the only company that froze the elec. rate so that as the lease progressed over the years my rate stayed the same.

If I purchase another E car next year I may expand my panels. The project is well designed. Customer service is consistent and well informed. read more
