Design and development of solar cells in electric vehicle prototype intended to Design and development of solar cells in electric vehicle prototype Case study electric cars of Rajamangala University of Technology Phra Nakhon. The research process begins with the solar experiment model Solar Thin Film a bent size 19.2 x 9.5 cm technology has applications in Unmanned Aerial Vehicle install to a source of clean electricity generation using 80 Solar Thin Film Cells controlled by Arduino mega size 101.52x 53.3 mm Programming software by Arduino-1.6.9-Windows and Show the result at LCD Solar Monitor Charger from batteries store the electrical energy size 12V/28AH 6 pack for the results showed that such a circuit can charge electricity 5A to 1 hour and to expand the use of rechargeable battery electric prototype instead of using electric vehicle prototype from charging normally Requires 480 Solar Thin Film Cells in trial period hypothesis 6 hour/day. In term of investment evaluation simple payback period is expected to be 4 years. Considering sensitivity analysis it is found that the most sensitive factor is electricity cost cost Solar Thin Film and the cost of Evlink Fast Charge Solution respectively. The results of this study can be used to support decision making in design and development of electric vehicle prototype in the next generation more efficiently

This project presents the simulation of a three-phase generator. The aim is to study and analyze the condition of the generator functions. By simulating the operation of the generator used in factory which use this generator as a backup power source to replace primary power source of electricity-supplier. In this test can start or stop the generator to determine the parameters at that time. The generator is used when the main electrical power distribution error and the generator is disabled when electric power system of electricity-supplier back to normal.

The purpose of this research was to investigate cooling water profile that effect to coefficient of performance of spilt type air- conditioning system. Air conditioner size of 12000 Btu/h was used in this experiment. There are three experiment of cooling water profiles in this work such as water spray water drop and heat exchanger profile. The ambient temperature conditions were controlled at 35 40 43 and 45 oC. The results of this study were found that heat exchanger profile had the highest average coefficient of performance and energy efficiency as 4.94 and 9.15 Btu/Wh which increased as 20.1% and 8.47% respectively when comparing with the normal working.

Now is a great time to be an entrepreneur as there are many solar business opportunities to develop. The market for solar products is growing quickly over last year so now this market is helping people get the most from the sun. The market and can be a great source of ideas for usage in the home and with your business. To measure efficiency of the solar energy in Thailand we have installed and tested the solar cell to detect and record the voltage electric current electric power temperature on the solar cell outdoors and check factors related to efficiency of the solar cell when high temperature and efficiency of the solar cell in various weather conditions. The following is the summary of average Wattage and used the Cumulative Sum Control Chart techniques. The Resulting research shows the direct current electric supply below: Solar cell “A” current distribute 85.78 W Solar cell “B” current distribute 81.19 W Solar cell “C” current distribute 95.65 W The temperature on the solar cell can be seen below: Solar cell “A” is 53.88 °C Solar cell “B” is 53.68 °C Solar cell “C” is 52.79 °C Summary of result is the solar cell “C” has highest electric power and the least temperature and this solar cell “C” suitable for use in Thailand. This research results is only relevant when deciding which solar cell to select

This research aims to produce scrap page kaolin of brick construction. The kaolin clay ratio of 100: 0 80:20 60:40 50:50 40:60 20:80 and 0: 100 by volume Add mixed with rice husk and rice 15 percent by weight A total of seven ratios. According to standard tests or TIS. 77-2545 ordinary story brick building. The moisture content and water absorption is increasing. While density Thermal conductivity resistance flexural and compressive strength tends to decrease. The best ratio of 80:20 by volume with compressive strength 43.16 kg / cm 2 and 24.93 percent water absorption. Criteria standard of TIS. 77-2545 requiring compressive strength not less than 35 kg / cm2 and water absorption must not be higher than 25 percent. Can be used in the manufacture of brick construction including building decorative wall can be developed into products. Because skin color and beautiful
