I came across this project which is laid out in detail for a solar powered webcam. The author does a great job in explaining in detail about each step. He even provides various links on the different phases of the project. It’s great reading and will more than likely be a spring time project for me next year.
I agree, I think the panel is too small. It’s a pity because I’m seeing 50 watt panels available now for not much more than what I’m guessing he paid for that 15 watt Sunforce. Also he could improve the efficiency by dumping the invertor and feeding the cam directly with DC (regulated as necessary). Other than that it’s a very well described and implemented project :thumbright:
http://www.ecodirect.com/40-Watt-Solar-Panels-s/26.htm This site has some cheaper panels. I purchased two of the 80 W Sharp panels to provide lights… power to my shed. Shop the prices and you can find what you are looking for.
Keep in mind that you may want to combine more than one panel but that is more real estate. One higher wattage panel may be a better option because it is easier to mount and usually provides more amperage. I would also recommend making an adjustable mount to adjust for the angle of the sun. This changes depending on the season.
Another thought, most of us have weather stations, place the panels angle to match your latitude. Mine is 34 degree’s. This will help make the panel more efficient.
