Anyone Use Hightec Solar Panels

Wondreing if anyone has experience or knowledge of these panels? They sound ok (as all do) but can't find any reviews of them. Not sure if the clear back so the reflection can make power on the back side is a gimmick or just new to me. Thanks in advance.

No experience with this brand, but bi-facial panels like that have been around for some time. They were pioneered by the Japanese, and are very efficient in raised systems with white background to reflect light. LG of Korea is currently the largest manufacturer of bi-facial panels, but others are growing rather quickly in this solar segment. They are used over patios, and as car port and garden structure roof panels. I am not convinced they would be very efficient on a low mount system on a white RV roof, but do know they are much more efficient in ground mount arrays than the traditional dark background panel. The few I have are ground mounted and generally run 50 degrees F cooler in direct sun than my regular panels in the same mount configuration, and a cooler panel is more efficient.

Not a very good price for a 200W panel.

For a smaller physical size 12v panel made in the USA it's not bad.

I'd give them a try. My first 2 panels came with a 20 year warranty. It will expire next year, and the panels are still working well. What is the warranty for these?

25 year, transferable. They buy the cells from Solar World and build them in MI.
I was hoping for input from someone who has used them. The price of smaller ones that fit on an RV are more than I paid for my 325w at home.

I paid 55 cents/watt for 100W panels (10 panels for $550...used 9) that are 2’ X 4’ which were the size I needed for my DIY installation. Guy had 100 of them on Craigslist 90 miles away. This “deal” was the deciding factor in my deciding to install some solar...all in price is $1.40/watt with a Flex 60A mppt controller ($450).

I just purchased the same panel yesterday. I will be installing on my coach in a week or two with a MPPT controller. I will add a second one if it performs well. I am not
real solar savvy but I have been educating myself on panels for a couple months and chose this 200+25 panel with the clear backing. I would look at controllers and choose carefully as the controller is as important as the panels. I chose the Regony PG 40amp without the remote monitoring stuff. It was about $120.00. I believe it will be proper size for the two panels.

12 volt panels won't properly charge 12 volt batteries.
