Incompetence

I had Nava Wassrler come to my house and give me a good price of $193 a month fixed rate for 47 panels. I told them I have a Anker Solix e10 system (battery backup) and wanted to make sure their system is compatible. I her this day one. That was July 23rd. They came to the house, did evaluation of the roof and the anker system. And twll.me July 30th, that the system isn't compatible due to radio frequency interference. Smh.

After support is terrible

I had my solar install by Solar energy world in Sept. 2025. All was going well for a few months. Then we lost connection from our app. I made my appointment, which took them 2 months to come out, and they determined the cellular connection was failing. They told me I need to run a category cable to the array. I did a ground unit, so this means trenching about 150' add pipe, cable, ect. It seems to me a company that knows what they are doing would have tested the cell signal, which sucks at my house, they should have asked me. So when the electricians pull the wire from the array they could have pulled a cat6 at the same time. Shame on you solar energy world. I will not be recommending you.

Install was great, post install service is not good

The install process went well, the slow parts were all due to county permitting and inspections. Post install it took FOREVER to get someone out to do the drywall repairs in my garage. Now the next challenge is that I had an inverter issue and a panel not producing as well as it had. By the time anyone respond to the issue I reported the inverter error had cleared but the panel is still producing ~40% less power than it had before the errors. Now they are telling me they will charge me to come out and take a look at the panel and inverter. It took 9 days and I had to call to actually get them to start to address the issue.

dissatisfied

difficult to deal with during the installation process. Still don't have the email with the information necessary so I can monitor the system. I had to threaten them with kill the project to get it installed in 2025 so I could take advantage of the tax credit. If i hadn't pushed the issue I would have lost the tax credit

REPAIRS

They were good about installing the system, but when there is a problem, it is taking them 3 months just to send a technician out to us, and they are charging $149/hour including their transportation back and forth! They have us over a barrel since it is their system. I'd look elsewhere.

Numerous Problems

Typical big company, bureaucratic and slow. (BTW - They are a wholly owned subsidiary of Comcast Corporation which may explain something.) Before you sign they are very responsive but after you sign and they have you under contract they are not. Verbal promises mean nothing - something I forgot. I was told all installations got a "critter guard" but not mine since it wasn't in the contract. They made a big deal about the site survey and obtaining the engineering drawings for the barn so that they would design a code compliant system and be prepared for the install. But on the day of the install they came without the correct mounting hardware for the rails or expansion tubes for the electrical conduit so that wasted most of that day. Once they started the actual work, they drilled five "extra" holes in the house and barn and realized they were in the wrong spot. I think that's pretty poor workmanship. After the installation, they wasted about a month because they didn't a tech available to meet the township inspectors instead of simply leaving the permits. Then once inspected and they received the township approval, it took nearly more two weeks for them to submit the form letter to the electric company for PTO. More wasted time. Their portal seems like it might be helpful and they promise a quick response but that doesn't happen and you won't get a copy of your request unless you take a screenshot. Very unprofessional. Just recently, I got the PTO notice and since being powered-on one of the house's arc fault breaker has tripped 6 times. That's clearly more than a coincident since in the prior 4 years since the house was built that breaker never tripped. I've just called this in along with a problem with the Enphase gateway meter. So I'll need to see how they fix this problem. If you choose this company, good luck. I feel like these guys are like the aluminum siding salesman from years ago.

No respect for timelines

This company is quick to go to contract and unwilling to stick to timelines. I just wanted to add a battery backup and it took 6 months for it to be operational. My salesman seemed annoyed with my questions about timelines and wanted to place blame on me for switching from financing with SEW to my own financing (a 3 day delay at most). Additionally the team at SEW screwed up the paperwork several times with our power company. The product is fine… the installation crew was GREAT… but I do NOT appreciate being treated like a pain for making a significant investment.

Great until something breaks

We have 1/3 of our panels not producing energy going into the summer and are told that we have to wait over a month to get a person to even come out and look at them. Based on interactions so far I’m worried if repairs are required it might be much longer until the repairs are actually done. That’s unacceptable and makes me very worried about continuing with this company although I’m not sure I have much of a choice. They were great for install, but support so far is not great. Their response was literally, “well, other companies take longer.”

Response from Solar Energy World

We understand how frustrating it is to have a third of your panels not producing energy and to face a long wait for service. This is not the level of support we strive to provide, and we are taking your feedback seriously. We are committed to resolving this issue as quickly as possible and ensuring that you receive the support you need. Please reach out to our customer service team directly so we can address your concerns promptly. Thank you for bringing this to our attention. Best regards, Solar Energy World

Excellent sales but post installation terrible service

Installation was expansive. We chose this company hoping the service would be good as promised. But post installation service is NO good at all. Our solar system lost communication and there has been no data reporting online for more than two months. Called and emailed the company and some point of contact people (e.g., the service manager) many times but no responses.

Back office doesnt communicate

Did great work upfront! It took too long to get finalized and their communication was very bad. They did my loan 3+months before they installed which not only did they mess up and now refuse to communicate with me, but my 18 month, no payments, loan will be due prior to getting all my income tax back (from energy credit). Again, mistakes happen, but don't expect good communication from them. Avoid this company!

Satisfaction review.

The initial presentation and sales pitch went well.Once I decided to go with you, Things took exceptionally long.The electrician did his thing but would not take the pipes thru the joists but rather under. Then he moved the circuit breaker for my furnace to somewhere and did not relabel the breaker box. When to crew took down quite a bit of the foil backed insulation to install the inverter and indoor meter, they did not replace any of it and left some of the bare wall showing. I have already recommended my brother who had some of the same issues. I now have another neighbor who asked me about it.

Good then bad

My first install went very well. The salesman came to the house to teach me all about SRECs and how it all works. The install was smooth and professional and it all worked as advertised. Several months later I contacted them to do a small add on solar system, to which they slow rolled me and kept not answering emails which delayed my eventual install several months. The monitoring tool for the second system was not integrated into the first, so I had to ask them to do that. The technician scheduled, confirmed and then didn't show up or call until 3 days later. I had taken off work to meet him so this was damned inconvenient and I never rescheduled it. Further I had to prompt them to send me a receipt for my taxes. The difference between my first install and my second was like working with a different company even though it was the same sale rep I worked with.
