Hello Michael - looks like this was processed and refunded per your request. The MPN/ Spec Sheet does state here the exact product being sold, but as it is part of a system, there was an image that showed it in tandem with its compatible parts. Glad we were able to resolve all, and so sorry about any inconvenience caused on our part!

too long to ship and receive.

Hi Stephen, I am so sorry about that there was a delay in recieving your part. I'm issuing a discount card for your next purchase should you need anything else. This particular product's manufacturer was late in delivering. I've emailed you with more information!
Again, our greatest apologies for the inconvenience. We know you have many people to choose from, we try to provide access to these hard to get products, and it pains us when we can't deliver in a seamless way!
You were late in shipping the product, and continued to ship the product even after being told to cancel the order. The package has finally arrived, after you were told to cancel the order, and is ready to be returned. Please issue an RMA and refund the purchase price.

Hello Michael, Happy to have helped you today in a full refund. We are sorry that it was not shipped out in your expected time period.
Unfortunately, the mechanisms of the supply chain are sometimes hard to stop in progress! We try our best to align with unexpected cancellations, and we're glad we could rectify things in the end. Please let us know if you need any other support with your solar project!

They found a hard to find item for me.
I was looking to purchase an item that was very popular and was listed as “Out of Stock, On Backorder” on every site I visited. However US Solar Supplier was able to locate one for me and shipped it as soon as they could. Shipping was very fast and delivery was professional and courteous. The package arrived is perfect condition indicating very careful handling through the process.

Hello Christopher, Thanks for the kind words about our shipping and delivery— we know at the end of the day it's not just the purchase but also final arrival! We're glad we could find your item, please let us know if you need any other support on your solar project!
Took over one month to deliver my part. $25 shipping and it took over 30 days to arrive. I would not recommend this company to anyone ever

Hi Jacob, we're sorry for the experience you had. This item is normally sold in case quantities of 20, but due to a system oversight, your order for a single unit went through. We had to break a case to fulfill it, which caused the delay—our mistake, and we didn’t communicate that clearly. You did receive the item, but we completely understand your frustration. We’re updating our system to prevent this going forward. If you have any other questions, feel free to reach out to [email protected].

Design expertise, competitive pricing, fast shipping
Not all solar suppliers have staff with field experience and deep product knowledge. USSS does. Taylor provided an excellent design in just a few days. Equipment prices were lower than competitors and shipping was fast. I will use USSS for my next system!

Disappointed at first but we all learn and move forward
Edit: After an immediate response and the additional follow up today, I am more than happy to change my review to four stars. They earned it. The follow up to my initial review is worthy of reconsideration and, after several discussions with these folks, I can understand that some things just
fall through the cracks. We are all human. Their apologies were sincere and I will be back to conduct business with them again. I am confident the next review will be five stars. Thank you gentlemen.
ORIGINAL: At first, I was excited to be able to talk to someone from my first phone call. Seth was helpful with my questions and provided me his direct extension. Since then, crickets. No return calls so, after 3X trying, I used the website chat. Quick response, even after hours! So, I felt a little better about it all and ordered my panels during the Memorial Day sale. Good price and I received them timely in well-packaged condition - nothing broken or DOA, all tested working. Then I measured… WARNING! The USSS website panel specs are NOT actual panel measurements compared to the manufacturer website; they are “shipping“ measurements. Reached out again via chat (after hours) and the rep was nice, apologetic, and acknowledged the confusion. I told them I could possibly make it work on my RV yet they still offered free design change help; “just email Taylor.” On June 2nd, I sent a very detailed email and asked for help. At this point, I’m still leaning toward a positive review but, Taylor must be hanging out with Seth. Crickets. Today is June 11. No emails, nothing. Being forgotten is unacceptable and disappointing. Pre-sales was 3 stars, shipping was 5 stars. Service after the sale is ZERO. Someone should have followed up with my issue. Please do better.

Thanks for sharing your experience — and you're right, we should have followed up better. Taylor was genuinely sorry to have missed your email and was glad he finally got to speak with you directly.
You're also right about the confusion on the panel dimensions — the shipping measurements didn’t match the spec sheet, and that’s on us. We’re working on making that clearer going forward.
We’d still be happy to provide design services for you at no charge, whenever you're ready. Appreciate your patience and the opportunity to improve.

Great communication, will buy from again.
These guys stay in contact with you, and answer any questions promptly. They told me when my product would ship, and notified me the whole way. I will definitely buy from them again.

We love hearing this! Thanks for the great review. We're so glad we could keep you informed and happy throughout your order. We appreciate you choosing US Solar Supplier and are here for your next project!
Not an authorized Sol-Ark dealer. Anything purchased from these shysters is a purchase at your own risk. Contacted the manufacture and they sadly stated that they can not support it since it was purchased OUTSIDE their authorized retailers. So Sad, that even the manufacture does not want to deal with these people. - RUN AWAY

They actually get back to you, unlike 2 other solar stores I tried to purchase from and pricing is great!

We understand that in a competitive market, responsiveness and transparent pricing are what make the difference to customers like you. Thank you for highlighting our commitment to both!

Found the panels that I had been searching for. Good customer service. Would use them again.

Fast service
This was almost an impulse purchase. I stumbled upon their site, and noticed an unbeatable price on a pallet lot, with free shipping, but less than 48hours remaining on the sale. I had to scramble to pull together the money, and they scrambled to get the goods out the door.
Now I've got all the panels I need, and it'll take me the rest of the summer to procure the other components and build my system.

We're absolutely delighted to hear this! At US Solar Supplier, we believe in treating every customer like our most important customer. Your feedback confirms we're on the right track. Thank you for your trust in us!
Good overall experience
Andrew helped me get the solar panels I wanted and went the extra mile to have them delivered even though they needed to break down the shipment specific to my order.
Only issue was it took 2.5 months to deliver and I was told it would take an extra month. Fortunately I did not have the installation scheduled yet so it wasn't a major issue for me. The panels have arrived and so far so good.
