you need silicon metal carbon little gold lots of iron and surling, the first solar cell made was by the great inventor Alexander Diab who built it and didnt draw the dessign that was Antoine baccqurall
firstly you will need a solar cell 3V to power your electronic bell .after that you can make a 5Khz sine wave geneartor and connect it to solar cell and you should also use a timing and control circuit to cuttoff the bell after some time and when any one press the switch circuit energies and take the power from solar cell and alarm will start.
No, there is a lot of "stuff" that is not green needed to make the panels etc. Hydroelectric power is perhaps the greenest.
Solar energy can be harnessed to produce electricity that can power motors or engines, which in turn can make an object move. This can be achieved by using solar panels to convert sunlight into electricity, which can then be used to run the equipment needed to move an object.
metal + human = tool tool + sun = solar cell sun + solar cell = electricity
When the sun is out.
You could charge batteries directly from the cells if they are wired together right. Cells in series and parallel to make power is tricky business. It would help if they were identical but they are not. Now PV power management systems get the most out of all cells all day long.

HOW DO I GET A GRANT TO UPGRADE MY HOME SOLAR SYSTEM, WE DO NOT LIVE NEAR A POWER GRID, THIS IS OUR SOLE POWER, I ALSO NEED HELP REPAIRING BD FOUNDATION ON OUR HOME

they create energy using solar power that you can use to power electronics and things.

Charles Fritts invented the solar cell as a way to convert sunlight directly into electricity. Fritts saw the potential for harnessing solar energy as a clean and sustainable source of power for various applications. His invention laid the foundation for modern solar technology.
