A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. Question 29. Light shining on the solar cell produces both a current and a voltage to generate electric power. Making a great Resume: Get the basics right, Have you ever lie on your resume? At night, you draw power from your utility. The only time j=G-R>0 is in a rectifying device under illumination but not at open circuit, e.g. Viva Voce Questions on Polarimeter . The maximum voltage, on the other hand, is fixed by the material the solar cell is made of. So plan your future as Solar Engineer, Solar Panel designer, Solar Project Engineer and so on by looking into Solar Power job interview question and answers given. The result is the approximate size of solar array, in kilowatts, needed to meet your electrical demand. The VI characteristic of a solar cell is shown in Fig. Question 4. Post a Job. Question 22. Series arrangement of solar cells. If your state does not provide for net metering, you can still use the electricity in your house and enjoy the benefits of clean reliable power from the sun. It is important to understand that a solar electric system does not need to provide all of the electricity you need to be of great value. Answer : Solar electric modules are typically one to two inches (2.5 to 5 cm) thick with 32 or more three to four inch (7.5 to 10 cm) blue or black solar cells on the back of the cover glass. Silicon Solar Cells by Martin A. ANSWER: a. c. Recirculated after cooling in cooling towers. The direct current is connected on cables from each row of panels and flows into power inverters where it is converted into alternating current. Most of the related system components should also last for many years without problems. 6.What is short circuit ... What are the characteristics of laser?
