4-16-2014 :OK – thanks for all the comments and views…..here are some answers for the frequent questions…. The panels are Helios usa made 255 watt model x 4 cost about 2,000 w shipping. The Aims inverter is recommended for 700+ $ -its still working- and I MOVED IT INTO THE CABIN away from the batteries…..yes the battery box is well vented at the back. It almost never freezes around here……even water ….let alone battery acid…..some places in the country will get that cold …. but not here. The total cost with lumber batteries and a cheap charge regulator was 3,800. It was build AFTER I found out how much the cabin needed. There is no need to overbuild when money is an issue. It works great and only ran out of power once. Thanks again for all the views.

Main Features:
1.High efficency SUNPOWER monocrystalline solar panel,solar conversion effeciency up to 25%.Most panels in the markets are normally 15% or even lower
2.Dual USB port,20w/3.4A output provides enough power to charge two devices at a time
3.Built-in intelligent chip, equipment’s current can be automatically identified and achieve quick charging.
4.Suaoki solar panel charger is 1/3 lighter than the same power of monocrystalline solar panel, which is easy to carry for camping,hiking,and other outdoor activities.
5.Equipped with four hooks, easy attachment to backpacks or other places
