It gets to the key of any solar project, what's the exposure. We are out in NV where 100 watt panel and 2x124 amp hour batteries is more than enough all year to span cloudy sessions. We get one full day and we are recharged and rarely go a week without one day of enough sun to get another week of run time until we get the period that everything is fully charged. More panel gets you back up faster so Sam's setup will get him back to normal in 1/3 the time = 3x the clouds.
BTW set your solar panels for the maximum sun declination. That's when days are the shortest and the need for power is the greatest and usually the weather is the worst. It also helps with the snow issue. By the time the sun is higher the days are longer and you make up for the bad angle with more exposure/better weather...
