Solution

It's a cart made with galvanised sheet and mounted on two bicycle wheels. It consists of two symmetrical parts, articulated by hinges at a mollusc bivalvo mode.
Each of the parts or leaflets integrates a photovoltaic solar panel and also has a space to put up components, alarm, motion sensor, water pump, hose, chain, irrigation drop by drop, multi charger (of the type Ecoboxx, Yake, etc). 

 

Solar panels are fastened with two separate structures, which are attached to the valves. 
At bottom of the valves is set the wheel axle. This axis is articulated in such a way that allows raising the valves and open them. 
In this position the valve leaflets are supported on wheels. Given that the other end of the valves relies on earth, the panels are oriented to the sun with the angle that determines the height of the wheels.
One piece closes the valves and allow the cart to be handled by one person as well as allow you to tow onto  a bicycle or a  motorcycle. This piece is equipped with a lock that prevents the manipulation by unauthorized persons. It also has an articulated support for fastening to the moto/bike rack. 

Within the space intended to accommodate the components is placed a box with its lid and a padlock which shelters the movement sensor and alarm. This box is also made of galvanized steel and is welded to the structure.
The solar cart can also be used to charge batteries which will feed power for refrigerators, charge phones cell phones, computers; lighting, etc. The size of the cart can be adapted to the dimensions of the solar panels so that it is valid for all types of current and future solar panels. This will allow increased power technology evolves. 

In the current state of development of photovoltaic solar panels the maximum power of the panels will be 300 WP each. So the maximum total power is 600 Wp. 
Another version for 4 solar panels is available but that, failing to check the costs of manufacturing in the India, perhaps exceeds the cost established. 
As we know in the next few years this power will be significantly expanded.
The price in Spain is €1,249.26 (1.673 USD) which slightly exceeds the established cost. However if it is manufactured in India - as it is our intention - the cost will be less than the established.

The "India Micro Inverters" supplier has DC pumps that meet the required flow. There are many other similar.
Also the India solar panels manufacturers can supply them at reasonable price. 
In the same way all components, plates, wheels, alarm, hose can be supplied by manufacturers of the country. Our intention is to manufacture ourselves by putting up a factory in the India.

Observations:

The presented model is a prototype. We have detected small errors that will be corrected then.
