Flawless Solar Installation!!

I can not rave about Castor Solar, Inc. and their crew enough. The entire process from signed contract to install and permission to operate was seamless. Our system was installed within 30 days of signing the contract. The install took less than a full day and the crew was very polite. The Final Inspection passed the next day and then we were granted PTO within 3 days. I've heard horror stories from friends that have used other companies. This company is top notch. I wanted to wait to do a review until we received our first electric bill. We just received it on Monday and it was for only our connection fee of $30 when normally this time of year we'd be paying $210. I'll be referring Castor to all of my friends and neighbors.

Straight forward, Fast service, Solid Price

I did my research for about two years before I went solar. Since there are so many companies out to just make a quick buck versus actually trying to sell a product they stand by it was hard to find a real company that would not screw me over. To many sad stories of bad contractors, crappy equipment, people saying their electric bill is higher now than before having solar installed. It's crazy out there!!! But Castor Solar is the way to go! Start to finish, (I mean contract sign start to my power company allowing the system to be turned on), was 3 months flat. Actually a week shy of 3 months. The installers were smart, they handled everything like pros, cause they are! If you're in Florida or Texas, pick them!

Very satisfied and I am hard to please.

I am very technically savvy. I research part numbers, the plan, pay for third party review of plans, and I critique the contract with a fine tooth comb. Hear the short story. I got Q. Cell panels and IQ8+ inverters. By any standard these are considered top of the line hardware. In addition, my cost for this system was very, very competitive. Most solar company have two prices. Cash price and financed price. The problem is, the desirable monthly payment on the finances price is always with the tax credit being sent to financing company. So you get the solar system and the Monthly payment is close to your current electricity bill. However, you do not get to keep your tax credit. Castor was different. Now, idk if they’re able to give everyone as good of a deal. But, I was able to finance what was equivalent to other systems cash price with incredibly favorable terms with Mosaic. So… Top of the line equipment. Honest pricing. For me the finances price is where is should have been with all these other price gouging solar companies. The best financing plan possible (which unfortunately could change due to the nature of our financial climate). All this means I got the best deal out there. I went through 15 bids and Castor won. Others were cheaper but their equipment was as good and I had concerns about the installers and customer service. Castor for the win! Now, I background check my salesman, my rep and one of the partners of the business. I couldn’t find any concerning history. I did my part to reach out to my contacts regularly and I always received the information I needed. My reps have always been accessible and pleasant to work with. So far, I have no regrets going with Castor and they have been good for their word up to this point (couple weeks since installation).

Great products quick install best warranty

After researching multiple options it was clear that Castor solar was offering the highest quality equipment available. Tier 1 materials with a 25 year warranty. Install only took one day. System has been functioning great ever since then my total electricity costs have gone down 30%. Kirsten has been an excellent point of contact along the way.

Great Install, but failed to many times

Didn't have any problem with the installation or the workers THAT day, they did a very good job! But based on what TVEC gave to you guys(through email) on what NEEDS (Not recommended) to be installed, the company failed to do so. Not only did they fail 3 times before we could even get it started but, the TVEC worker showed me the email and template that was sent over to Castor Solar which failed to install what they(TVEC) asked for. Castor Solar wasted so much time as well not notifying the TVEC that everything was finished the FIRST time which caused a 2-week delay. I had to reach out to the roofing company to ask for help to get Castor Solar to call TVEC to let them know it was installed. Now, on to the third failure. TVEC came out again and notified me that the CTs were not properly installed to the breaker and that they just threw them in the meter box which was a "no-no". He said "They know these have to be connected to the breaker so we can not turn on your solar until this is fixed." Luckily you guys came the next day got THAT fixed and notified TVEC which came back out the following day and got it approved. Again, the workers need to know that they need to install everything the electric company asks for PROPERLY instead of trying to cut corners and say "Well, sometimes they don't notice unless they are very experienced in installations" Well, thank goodness the guy who came to look at our house was very experienced otherwise who knows what I could have been missing. Proper training needs to be taught to your crews from now on. All these hiccups almost caused me to cancel everything and return the solar and go with someone else. Thank you.
