200W CIGS Solar Panel

For those who don't want to drill holes in the roof of their RV, this is a very good option. There are four adhesive strips on the back and the backing strips come off easily without mess even in hot weather. The adhesive is some sort of roofing cement like Henry's or something. Once the panel is laid down, it is not coming up. The panels are very flexible and durable. You can walk on them with no problem. I installed four 200W panels and at high noon. I am getting a total of 670W. Decent. My only real gripe with these are the price. They are spendy. However, Bouge often has deals on these and if you are patient, you might be able to pick these up in the low four hundred range. For me, the BougeRV Yuma 200W CIGS Thin-Film Flexible Solar Panel were a solid winner.

These are excellent solar panels for a motorhome. They work great in low light levels. I replaced all of the standard rigid solar panels with Bouge and was able to double my output because of better use of space. I was able to go from about 400W to 800W rated output. Three 200W Bouge with adhesive strips and two 100W Sunpower. Installed them about two years ago and so far all is well.

Failed in less than a year!!

I was hoping that this would work after the dismal performance of the other 200w CIGS panel I bought on Amazon (that company is no longer there, so I cannot leave a review...the slate has been wiped clean). The BougeRV unit arrived on time, well packed, and in good condition. It was overcast, and I first hooked up an ALLPOWERS solar generator to test it...zero watts. Then I hooked up a 400w SUAOKI SOL-GEN and it showed 72 watts. Next a Bluetti 268w SOL-GEN, which showed 172w! The ALLPOWERS is a very mediocre unit in all ways. so I wasn't surprised. It probably has a cheap PWM contgroller. The SAUOKI has either a good PWM, or a weak MPPT charge controller. The Bluetti obviously has a top-notch MPPT controller. Remember this when you test a new panel or other device...a system is only as good as its weakest link! This 200w BougeRV CIGS panel will be mounted on my motorhome roof to replace an 8yo one that has degraded. I have high hopes that it will make a big difference, for a long time. I will update after a few years.

Good output, even on cloudy days!

Added two of the 200 Watt flexible CIGS panels to the front cap of my 5th wheel. Chosen for being very light weight, and ability to work even when partially shaded. Also chose the CIGS for it's flexibility and safety with no burn through issues. My 2 panels have been working great for over a year and a half.

Rooftop rv roofs. Will work for a zero maintenance effort. Is exactly what you need for rv roofs. With lots of variables where a house roof is 10x better for solar and rv aren’t. 2 years on my rv still powers my lights fridge and cooking with 2x100 ah 12v lithium batteries. Crazy good. Also San Diego weather.

I'm unfamiliar with standard or expected efficiency loss when solar panels are not mounted precisely perpendicular to the sun, but these panels seem to perform poorly under non-ideal conditions. 62 degree clear day in Phoenix, AZ - Sun at 37.7 degree altitude during daily median: Out of 200w max output (which the panel does produce when mounted precisely perpendicular), output is hardly 80 watts! When mounted within 15 degrees of perpendicular output still doesn't push past 120w. Also, partial shade and shady conditions cut output even further - a benefit of these is supposed to be improved output during these conditions, but I can't imagine a "standard" panel producing less than 20% of rated. Perhaps the above is typical for all - I'm not (yet) an expert - if so, disregard my ignorant complaints here! An off-axis correct factor would be great to have as part of the product specs, then the consumer could know what to expect in various conditions.
