We have a better solution
We are the manufacturers of Lightspeed solar co. We manufacture a solar energy storage box which is already being used by the US Air force. This can provide clean energy. The 3.0 model has 4.5 kw output. It can be attached to 4 to 28 solar PV modules to generate the needed power. It can also gather power from wind mills, generators and electricity for use during disasters. It is portable as it is mounted on wheels.
We are in the process of obtaining Li Ion batteries which can have a whole lot more stored power and can be much lighter. You can contact "STEVE BARKER" for further information.
