This is really not true. Case in point, today where I am it will be overcast, 85*F, and very high humidity. We also get extreme cold in winter, so there's no getting around needing both AC and heating, but solar isn't a panacea. Unfortunately, hot cloudy days also don't tend to produce much wind either.
- kolinko 4y agoI may be wrong but isn’t this an exception, not a rule?
- zdragnar 4y agoA bright sunny summer day will be hotter, but there's nothing magical about clouds that makes the need for air conditioning disappear unless you live in a desert.
- kolinko 4y agoAt least in my region (central Europe) cloud cover is closely correlated with temperature. As in - when clouds and rain come during summer it gets colder as well. I may be wrong here, no scientific data behind this.
- saltcured 4y agoThe AC system is not consuming the same energy in an overcast day versus an intensely sunny day, even if the outside air temperatures are comparable. The direct radiant heating of the structure with sun exposure introduces much more heat than the mere conductive transfer from outside air. When people say that AC costs correlate with solar power, they are pointing out that the same solar energy that increases heat gain for buildings during the bright hours also increases photovoltaic output which can be used to compensate for that heat gain.
