Your CPAP will use between 20-30 amp hours of battery in a 8 hour period depending on the setting. 200 watts of solar will deliver on average (with no shade) about 60 amp hours of recharge per day. If you have a single deep cycle battery rated at 120 ah, you would not have a problem running your CPAP using solar.
