Solar Panel question

Sep 04, 2008 3 Replies

I am looking for information about small solar panels for a new equipment design. The size will be sub 1W. I keep googling for info but half of the internet seems to be taken up with Solar Panel ads for large panels that, together with a suitable



12 1Ah battery and inverter, can be used to power most of southern Europe through this coming winter.

Where can I find some useful information about the performance of available small solar panels - or a suitable panel manufacturers website.



I am quite conversant with insolation determination.



Thanks

You don't say for what voltage, or minimum current in ambient indoor lighting. A fair number of small cheap ones are for calculators.

Farnell stock a few of the smaller ones and that will give you some brand names to help find others. Same for RS

You could also try surplus stores for bankrupt stock ex solar fountains and other failed gizmos that don't sell well.

Try the OEM modules from PowerUp.

Last we purchased, these ran about $20 US. (QTY-1, 1-watt panels). Very nice construction!! I solidly recommend them.

Of course, after prototyping, we outsourced to China for about $8 delivered, 500-1K quantities. Let me know if you need details...
