Design of Renewable Energy System - Essay Example

The capacity of the reservoir tank will be enough to store water for a three days supply of water. The pumping station will be self-sufficient and require no external power to pump the water to the reservoir tank.

A fuel Cell is a system that can transfer chemical energy to electrical energy. That means converting the reaction between hydrogen and oxygen to get electricity. These processes do not produce any air pollution.

Hydrogen gas helps a lot in the pump station because it can produce energy by reacting in a fuel cell with oxygen to produce electricity. It acts as a basic material in this Remote Pumping Station System Project because it can generate power.

Solar Panel contains cells that cover the surface of the reservoir tank; these cells absorb sunlight and convert it to energy or electrical energy.

The overview of diagrams is used to show the connection between the system and the components by the attached figures:
- The hierarchical diagram (Figure 2 in the Attachment) shows the basic parts and the sublevel of the Remote Pumping Station System.
- The context diagram (Figure 3 in the Attachment) gives the necessary information that we need to calculate to redesign the project. This diagram makes it easier to find out which formula we are going to use in calculations.
- The functional flow diagram (Figure 4 in the Attachment) explains the process and steps for either the general subject or specific subject.

From the experiments, we were gathering data that helped us to find out the measurements of the elements of the system:

- Experiment 1 (Table 1 in the Attachment) was to determine the angle of the solar panel. We used the load measurement box of the rotary We set the protractor handout at angle 0. Then we adjusted the solar to the lamp. We had to consider the distance between the solar and the lamp like 50 cm. After that, we wrote down the current (A) in CW (+) and CCW (-) at different angles between 0 and 90 by turning the solar.

- Experiment 2 (Table 2 in the Attachment) - we were able to measure the amount of hydrogen created by the electrolyte. We observed the level of hydrogen created, after each 2 ml increment on the cylinder; we wrote down the time it took to reach this increment with the current and voltage. We continued writing down the time until 10 ml of hydrogen was produced.

- Experiment 3 (Table 3 in the Attachment) was to determine the fuel cell consumption efficiency. This experiment looked like experiment 2, both of them done by creating hydrogen. When hydrogen had reached 10 ml, the light source turned off. At this time, there would be an electrolyzer storage gas in the storage cylinder.

We used several formulas to get the right data for this project. The first calculation was the water demand equals 2,250,000 liters and equals a 2,250-meter cube, the water supply for 15000 people in three days, and 50 liters per person per day in Nepal. We multiplied the number of people, days, and litter per person per day. Then we assumed the height of the tank to get the diameter of the tank which equals 13.82 meters.
