This video shows how to build a High quality Portable Solar Generator for 150 bucks.The video explains how I built a portable 10 watt polycrystalline Solar Power Pack with 18amp Hour battery. aka solar generator for power outages and portable renewable power.Look at 10 watt solar panels mono crystalline or poly crystalline for the maximum amount of power in a small size. 10 watt Black amorphous panels are way too big to be portable.I sized my system to be portable for charge laptops and tool batteries. If you want your system bigger or smaller use different size components. Decide what you want to power then get an inverter that can do it.
