I need to calculate power consumption for three devices:
- Laptop (with a Digital Camera) = 50 Watts
- Scanner Fingerprint = 35 Watts
- Scanner Signature = 35 Watts
I've read that a laptop needs 50 Watts and a standard scanner needs 35 Watts. So, I assume that I would need 120 Watts in total. Say 155 Watts, just in case.
I'd like to supply energy through a solar panel. This solar panel has to supply 155 Watts.
Could anybody tell me if I am correct in my calculations?
And could you recommend me a brand of solar panel for the devices that I need?
