The last century the earth experienced a huge booming of its population. The rate of this growth is the biggest ever and all major predictions estimate that it will continue. Goods are becoming more and more valuable; consequently their management requires precise decisions as well as accurate decisions.After the huge industrial revolution, the next huge step from humanity was to invent new ways of transforming the energy from the sun, into useful energy for all kinds of activities.

Practically, sun will not expire before the end of earth’s life, this fact drives to the assumption that these types of energy sources are considered renewable. Apart from energy, another major good that is fundamental for all societies is food. Agriculture, is the science that circulates allactivities related to food production. It seems that the future of both goods will find them bonded and especially food production will be directly dependable to the energy.

Adding to this, the demand for food production industry will increase and require more energy; hence it will add to the environmental depletion, by releasing CO2 to the atmosphere.The aim of this study is to present, a potential alternative solution regarding the covering of energy needs, required for farming activities related to the arable lands. As the car industry, gradually heads to the electric engines and electric vehicles, the Farming tractor industry will not fall behind with traditional diesel engines. Assuming that it is possible to manufacture electric farming tractors, this paper is studying the energy balance between solar energy generation and the demands of the farming activities in the field. The main parts of this concept are, the solar array scheme, the electric motor of the tractor and of course the battery that will store the energy from panels and produce it to farming tractor, while operating in the field. Except from evaluating the technical and financial feasibility of this project, this paper aims to enforce the combination of two fields into one; Agriculture and Sustainable Engineering to Sustainable Agriculture Practices.Solar energy, renewable, Agriculture, CO2, farming activities, electric engines, farming tractor, batteries, solar radiation.

   A solar cell is an electronic device which directly converts sunlight into electricity. Light current and voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy states, and secondly, the movement of this higher energy an external circuit. The electron then dissipates its energy in the external circuit and returns to the solar cell.

A variety of materials and processes can photovoltaic satisfy the requirements for photovoltaic energy conversion, but in practice nearly all photovoltaic energy conversion, uses semiconductor materials in the form of p-n junction. The attempt of this study is to examine if an electric tractor can fulfill all the farming activities in equal qualities and efficiency as the classic framing tractor. Currently there is no specific model of an electric farming tractor in commercial size production. Hence for the needs of this study the electric tractor will be assumed to be classic farming tractor with electric motor an no technical design details of any particular motors will be discussed. The traditional fossil fuel, which is diesel, will be replaced from electricity from solar PV panels and the fuel tank will be battery. Researchers have long looked for ways to improve the efficiency and cost effectiveness of solar cells.

The solar photovoltaic cell array consists of hundreds, sometimes thousands of solar cells that individually convert radiant sun light into electrical currents. The average solar cell is approximately 85% of the sunlight that hits them does not get converted into electricity. Hence the scientist has been constantly experimenting with new technologies to boost this light capture and conversion capability.

A group of scientist from university of Toronto discovered a nano particle called colloidal quantum Dots. This material is less expensive and more flexible foe solar cells than compared to the processed silicon in normal solar cells. Normal cells aren’t capable for functioning outdoor, but this discovery has made it possible.

Quantum dots do not bind to air and maintain their stability, due to this property they have increased radiant light absorption and also were found up to 8% more efficient at converting sunlight. Water and wastewater utilities can benefit from new floating solar power systems. By installing solar panels floating on lakes, lagoons or ponds. In turn, the solar panels shade the water, limiting algae growth and water evaporation. The floats have been approved for use in drinking water reservoirs.

The floating system is engineered to withstand 85 mph winds and change in water levels. By installing solar panels over a pond, the panels are naturally cooled, resulting in improved power production performances. The cooler environment also reduces stress on the system, extending the system’s life span.

1. At the moment, the Japanese currently have the largest floating solar power system in the world. Located at Kyocera, this massive solar panel farm is comprised of over 9,000 panels and it generates 2680 MW of energy every year.

2. The 10 KW floating solar power installation in Rajarhat, Kolkata is the first of its kind in India. PV modules to produce a minimum of 14mwh of solar power annually. Fig. No.1 shows that floating solar plant (blue) is 10.3% more efficient than overland system (red).
