Your Questions About Solar Energy Calculator
explain me about working of scientific calculator using solar energy when battery power is down?
that is, how a scientific calculator works when its battery power is totally down?how it works when it is shown in sunlight for sometime?please give me the mechanism involved in it.
When batt not available the triac is used so the base power switches to solar cell and there if it gets energy it emmitts power to 7-segment and again ur calc is on solar batt. When u replace battreis again the triac actives through batt power.
[URGENT] What are the failures and successes of solar energy?
may i know what are the examples of failures and successes that are related to solar energy? need them urgently.. thanks.
A failure, the need for vast quantities of clean water. To flush and wash the commercial solar cells.
A success, the ability to bring portable power to remote and off grid areas. Where only a small gas generator was possible before. Simplifies and eases the load while going to such areas. No need for gasoline.
A success, the use of solar power, as a direct water heat source, has been proven to decrease the need for normal means of home water heating.
A failure, the stable ability to bring a home under total solar power. By available area of panels, storage ability and days when less sun available cuts power.
A failure, the high maintenance, low output, and short life of panels.
A success, the decreased use and waste of small batteries for small electric powered hand devices. Like radios, calculators, over the life and use of the device.etc….
