Bucky is going to get an upgrade soon. I will get a 200 watt solar panel and learn how to install it by watching youtube videos. If you getting close to $1 per watt you are getting a good deal on solar panels.
Well I go me a German Certified solar panel from Ebay. Cost under $1 per watt and includes a solar regulator. Now to work out how to put it on my roof and attach it. Youtube here I come.
Was very easy to install as had roof racks and watched about 15 videos on DIY. Learning heaps about wire sizes, dangers of fire and the 12 volt system.
