Unisolar 128 Watt Flexible Solar Panel PV Laminate - 24 volt with quick connect cables. 216 inch x 15.5 inches - Peel & Stick

First off, I need to say the product is performing better than expected but it says it does this for the first few days, so far no qualms. Very easy to get pumping out juice and it provides amps even on grey and overcast days.Here is the issue, the manual shows the top connector as both negative and positive, and there is no + or - on the laminant itself. I believed it to be - on the top at first then took a closer look at the manual and it showed both - and + for the top.The top is +, atleast on mine they were +.The length of the laminants is a little hard to work with, if they were the same price for two half size ones with 50-60 watts each, and a connector was included to join them it would be great.The other thing is the bankrupcy of the company, and question of warranty on the product. It is gaurenteed for 20 years, and that is a real selling point. They are however selling at $200 each a real steal of a buy. I want to get two more, and would if not for the warranty issue, now I'm wondering? But the product is light easy to work with and very hardy. I'm not scared of a rock cracking it.Birds love them, but they are easy to wash off, or wash off with rain. Love the product, sketchy about the manual, it could be improved but is a great resource, and a + and - sign on the connection points would be great, as it caused some rewiring to be needed. A multimeter can fix this but doing anything with a new product is a little tricky cause you don't want to ruin it. None the less love it, and I hope the product survives and is picked up. They are way better than glass panels imo.

These panels are amazing! Beats messing with all that mounting hardware that you need with rigid panels! Not recommended for composite or wood shake roofs, but wow does it ever adhere metal! Actual output is about 110W @24 volts, so if you are getting these for use with 12 volts, you will need to step it down with a transformer or get an MPPT controller to do it for you.Super easy to install, but make sure it goes where you want it, because these are not designed to be moved later, unless you plan on moving the metal roof panels they are stuck to. Super tough against hail. Won't come off in a high wind. Excellent for RV or bus applications, but you need 18-19 feet x 15-16 inches unobstructed surface for each panel. You cannot cut these to shape. You can walk on these (but not with metal cleats on), but I don't recommend doing that.These probably don't provide the most watts for the dollar, but they have some big advantages in some applications.

I orginally ordered this product, but under further investigation I found the maker of thisproduct is know longer in business, it sort if nullifies any warrenty doesn't it

I installed as directed. I keep 3 12V Deep Cycle Batteries Full Charged with several items running all the time and an automatic Vent/ceiling fan when the inside temperature gets to 80 degree F., while the RV is in storage. No battery issues. Worth the money. Keep in mind once you install it you are not removing it.

Installed it myself in the most lazy and wrong way possible over creases and screws on a metal roof. Working great! It was as easy to install as a postage stamp and as durable as a welcome mat. Just doubled my order and have more on the way.

HAVEN'T USED IT ENOUGH TO SEE HOW IT HOLDS UP. DESIGN IS SUPER. I PLAN TO HAVE A WHOLE POWER STATION IN 5 GAL BUCKET AND THIS IS THE ANSWER. COMPANY IS GOING OUT OF BUSINESS SO HOPE ANOTHER TAKES UP DESIGN. IT IS A GREAT IDEA FOR MOBILE POWER.

How do they plan on upholding the warranty when the company that make this produced has gone out of business? Also, why the increase in price, especially considering the warranty problem down the line.Just wondering. . . . . . . . .

I have these on my RV and they rival the the big bulky ones that destroy the roof, the only bad part is when you go to sell your rv, they must stay with it as they are permenantly mounted.
