I'm having trouble understanding the application for this product. I have the 
tristar 600V CC in my own home.

If I want to have backup and also export to the grid, the Outback radian does 
that without the need to change anything over.  WHy would you want to have the 
Radian as a backup AND have a grid tied inverter, and have to change over a 
manual switch to provide power to the CC? What am I missing?

Wrenches,

 

I am looking for panels with a 20.1% efficiency rating or better, that are NOT 
Sun Power. My distributors can not acquire anything even near that. Any leads 
or resources to check would be greatly appreciated. 

 

Thanks!

Re: [RE-wrenches] 2v metal cased cells

[Phil Lawes]

Just curious if fellow wrenches are looking at Li-on batteries. We were just
quoted a 50KWHR at 48 volt battery pack with enclosure and BMS for $ 360.00
per KWHR or $0.36 per watt hour.

by Studer or Stecca but so far with European standard outputs.

Wrenches,
 
Does anyone have any experience, or thoughts, with/on this company/product?
 
It was recently brought to my attention. A 100W monocrystalline cell
bendable (to 30 degrees) module. Sounds counter intuitive to have mono cell
and bendable in the same module to me. My son is thinking of using it for
dry camping with his pickup truck. His small system would have 1 VRLA
battery w CC and this panel temporarily lying on the roof of his camper
shell.
 
Worth a try for $200?
 
<< The Renogy bendable solar panel uses advanced technology backed by
contact Sunpower Monocrystalline solar cells that have been laminated into a
flexible plastic sheet. The result is a solar panel that is far more durable
than traditional glass and aluminum models, with twice the efficiency
(approx. 20%) of flexible thin film solar panels. With these advanced solar
cells, you will get greater power efficiency even though the panel is no
larger than a traditional model. The plastic back sheet can be curved to a
maximum 30 degree arc and mounted on an RV, boat, cabin, tent, or any other
irregular surface. The flexibility of this panel also makes it ideal for
storage in tight spaces or crowded areas that are typically off limits for
traditional glass and aluminum models. While this solar panel packs 100W of
power, it only weighs a mere 3lbs, making it easier to transport, hang, and
remove. The laminate coating on the exterior of the panel makes it
impervious to saltwater splashing, rain, and other weather elements. While
this panel may be damaged by sharp objects or scraping, there is no risk of
shattering or cracking.

Re: [RE-wrenches] Cleaning Paint Off Modules

There is a product called Goof Off available at most paint centers for water

would need to use a product like lacquer thinner.

Latex paint can be removed with alcohol. Probably a rag damped with it would do 
the trick. It evaporates quickly. Still better check with manufacturer 1st.

If I am the customer, that painter just bought himself a row of modules. 

 

As a practical matter, I bet there is little problem with careful use of some 
kind of solvent, but who knows what the long term effects would be, and I 
certainly wouldn't take on that liability. Warranty could be an issue, if not 
some risk immediate damage.

 

Call the manufacturer. They would be the best reference in this case.

our customer for cleaning up this mess.

Anyone have recommendations of cleaning products or techniques to use that 
won't damage the AR coatings or anything else on the module, yet will remove
