2 different parties that I know opted for this type of solar and after a year's use have discontinued their use, opting to return to the standard glass surfaced panels.
Why?
I'm very curious also... why? Is there something I should know? I mean, I'm recommending this setup to others I know, so if there's something up with them I'd take it as very good advice.
Sorry, haven't been back for a while. It is always good to see others and their discussions too.
There is a couple that are traveling and posting their blog as they travel, known as; Gone with the Wynns'
Clicky They are switching out their RV for their next one and their recent reporting on this shared that they would not be going back to a stick on solar for their new one. Another Solar company that actually installs solar onto RVs specifically has come out and recommended that they are not the choice that they will install for their customers. After testing on their own RV. Then I have two different friends that have done this too and their Cons match consistently with each of the aforementioned users and one comment I feel unfounded. These issues are;
1. Impossible to remove if need of replacing.
2. Heat from panels and heat from surface (metal) combines to heat the panels even more.
3. Heat clips off amps generated with all solar during warmer months but at a higher rate/sooner with these panels and shortening the period of solar harvesting for the day.
4. Shorter Lifespan from glass panels
5. Cupping is created across the cell.
6. Dirt and Debris Collect in the concave of the cupping.
7. Cupping requires additional cleaning and care for flat panels
8. Due to the panel being polymer, they are not resistant to scratching when cleaned.
9. Marring of surface decreases the capabilities of solar collection.
The point I find unfounded by those casting negatives on flat/roll solar panels is the deep discounting is often from companies that have gone out of business. This has happened to a greater degree to the glass solar panels too. So I am not sold that this is an indicator.
For me, these type panels are great to use in applications in circumstances a glass solar panel is prohibitive. Such as a remote jungle location where these need to be carried in and in backpack/biking situations.
While this would not be my choice, and isn’t, for Solar collecting. But I am fascinated by the use opportunities that these type panels are providing. What greatly concerns me is when systems are installed without safety and true evaluations of what is safe for amperage in cables. As well as installing system components within prescribed distances as well as proper/safe cable sizes.
An earlier poster (tony_lee) wrote about how battery banks and proper charging regimes is something many should consider, for their weekend use and vacations. Interestingly I wrote an article on this very point a couple of months ago that will be coming up in a couple of weeks in Truck Camper Magazine. As too feel this is an important point that should be considered. Again, by sizing even your battery bank, one should be aware of the safety fuses and proper cabling for the available Amps.
