I have a small project I'm working on. I want to use a solar cell to charge a 1.2V 1000mAh battery. My project will work something like a garden light. But instead of a light, it will output an electric current straight from the battery and work during the day. My Question is, What size solar cell should I use to charge this battery? And I'm not sure what blocking diode to use. Below is a replica of the schematic I want to use for the day time.
I also want to make another one that will work at night. Below is another schematic that includes a photo transistor. Again what size solar cell should i use? And do you think adding another battery would provide a longer cycle without dying?
These are the only questions I can think of for now. Oh, and if you can't tell, I'm completely new to electronics :roll:
