Top three panels made:
SunPower (you'll pay a premium for this product)
Panasonic
LG
They all have 25 year warranties. Panasonic panels are made in the USA. They have been in business since 1918.


There are other solar panels that use the sunpower solar cells..Bougerv is one..I just watched a video on there site of there 170 watt panel($179) and Hobotech got 168 watts out of the 170 watt panel...I am not sure if this panel uses the same sunpower cells as there flexible but 168 out of 170 is pretty awesome..

Currently they changed there panel to 180 watts and it's not shipping yet but it does have my attention as I need a permanent solar panel for my new battery in my TC.

Hi Mex,

The best of the best right now are 6 junction cells. 41.7% efficient under 143 suns and they said that they have achieved an efficiency rate of 39.2% under one-sun illumination.

I don't think I want to know the price.

What has me cranked up at the moment is NPN Gallium Arsenide 900 PIV transistors.

2 milliohm junctions, and up to 120 amp rating. The end of mechanical relays for high amperage DC. No more heat sink issues. Battery management miracles. But let's not talk about price. They are a product of CREE. The idea of silicon carbide LEDs is enticing. New tech is arriving.
