This project presents an electric bicycle equipped with Solar Cell which will charge the battery with a solar panel. To be used to drive electric bicycles electric bicycles can be powered by two systems that are powered by the users cycling and from brushed DC motors from battery charging with solar panels the test will be tested by charging the panel with a time interval that the output voltage value From the solar panel which time interval is closer to the actual panel at 24 volts and charged into the batteryto test whether the electric bike can actually be used by a test drive starting with a displacement speed of 10 and 20 km/h at a distance of 100 meters. Using experiments with weight sizes of 50 60 and 70 kg respectively it was found that electric bicycles can actually be used. However the above project has been made into two parts. is the part that charges the battery from the solar panel and the second part is a separate electric bicycle.

The purpose of this research was to improve the efficiency of solar cell modules by cooling with heat pipes. The test set consisted of three 80 watt solar modules that were made of mono-crystalline. The first module did not install heat pipes while the second module installed heat pipes using ethanol as the working fluid and the third module installed heat pipes using R-11 as working fluid. Solar radiation intensity electrical energy produced by the solar modules and temperature of the solar modules were recorded. The results showed that the average temperature of the first solar cell module was 52.9oC and the case of not install heat pipes on module. For the units with heat pipes it was found that unit with ethanol heat pipe had an average temperature of 50.7oC and efficiency at 10.2% whereas the unit using R-11 heat pipe had an average temperature at 49.2oC and efficiency at 11.8% From the experiments it was concluded that the installation of heat pipes could increase the efficiency of solar cell mokules.

Research presents the design and construction of a prototype device alert to clean the solar panels. The measure monitoring of dust and blocking dirt surface of solar panel causes generation Energy low efficiency the devices are alerted to clean solar panel to ensure generation Energy highest efficiency and reduce the cost of solar cell cleaning which will be done 12 times a year. Researchers have introduced electrical and electronic technology with solar panels to provide a reference. Take an installed prototype in process with solar panel energy factory. After that clean the panel referred to the morning every day. This prototype will be processing performance comparison between the solar panels reference with the solar panels factory every day and results via the Internet and record the data in memory. The results of this research found that. Efficiency of electricity production is down 9% as 3 months and 10.47% of the year due to impurities. Dust cover doing have been cleaned twice the efficiency of the electricity production has remained high. This will alert you that washing does not have to be done 12 times as practiced in a solar farm reducing costs 10 times a year.

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

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
