You see 4-star rating and think; this must be a trustworthy company with good products. You must think; I can count on their expensive products doing what they are selling you. You did some quick research and saw the string of negative reviews that are recent but still let them gaslight you into thinking the company can be trusted and there may have been a few bad apples within the company that were purged from the company after they were discovered. This company is messed up at the roots, they will sell you an expensive product that doesn't work as promised and leave you hanging as every salesperson and project manager disappear and stop responding to calls and messages once the install is completed and the sale is done.
I feel ashamed to let them talk me into going solar again as the made false promises and stop responding to my concerns. I've been here before with another solar company that went out of business. I was promised savings on my energy bill but in reality, the saving I was making was immediately negated by the monthly payment of the solar system. I didn't want to be in this position again as when the system stopped working, I paid the full price of the energy bill plus the solar panels. Top Tier sold me system that isn't working because it is not activated and they are slow to respond. I'm paying for the battery and the full price of my energy bill while they drag their feet on activating it. I just thought it wasn't working but they told me poor performance is due to the system not being fully activated and I need to get a permission to operate letter from my power company. The power company is cooperating, but I need Top Tier to actually help me give the power company the information they ask for to get the letter. The project manager drags his feet and doesn't respond, and the sales rep is doing the same.
To make things worse they had a quality assurance personnel try to sell me a more expensive solution as a fix. Never again! They wanted to sell me a 22Kw propane gas electric generator to get me off the grid. They already told me the max consumption battery will do just that and give up to 300 credits per month of energy credit. I'm not seeing anywhere near that, and I'm not supposed to trust them with a more costly solution on top of the current solution I'm already paying for? The quality assurance person placed me on speaker phone with a big sales executive who talked like he was pretty high up in the company. He was trying to give me all kind of deals off the price of the product, but I'm already stretched with their current non-working product so it was a hard no for me. I was on the phone with him for well over an hour before he started to gaslight me telling me how I have trust issues and telling his quality assurance specialist who came to my door that it is not her fault and she is doing everything right, that I'm the problem because I have trust issues. Obviously, they are not in my shoes and couldn't care less about my experience with the prior solar company which at least have the excuse of going out of business; a now their company that is actively screwing me over with high prices non-functioning systems that they seem to care less about giving me any kind of priority to get things working while I'm still paying of the loan I took up for their product. They have the nerve to try to sell be a more expensive product while I'm in the middle of this.
Solar power is a waste of time, sanity and finances. It will work in niche situations but as long as you have to pay for the system if you don't have the up-front cash for it, you aren't seeing any savings. By the time you pay off the loan, it will be time to get new panels again as they have about a 15 to 20-year lifespan. You are not really saving anything. Save yourself the headaches of having to deal with terrible companies like this to put yourself into expense while the company leaves to high and dry.
Recommendation: You may see 4+ stars on BBB, those were from early customers heed the warnings of the slew I recent 1 star reviews. I wish I did.
