So I noticed after the last big snow storm with a foot of snow on my panels not producing much if any output even though going through sunny days the system is defaulting the days weather CONDITION value of SHOWERS when it has been sunny days all along in my case. I have the Open Weather API set and temps being recorded. I dont know if PVO is using some set of algorithm that between no production or very little and the Open Weather API values it sees it is determining the condition as SHOWERS.
I think it should be set to NOT SURE if it is not getting some OWeather API value that indicates the actual condition for that weather station I am using at best if not the right value the Open Weather API is providing. How else can you determine what the condition should be? Please fix…
I find two nearby installations here say different weather reports. AFAICS it uses a more pessimistic report from the bigger (one is 75kWp vs. 1.5kWp - but less than 1km apart, so obviously the same weather). Generally my little 1.5kWp is more accurate.
However, I’m somewhat bemused by you Aussies about SHOWERS - which for we Brits means about several minutes or so or rain interspersed with sunshine (which for us is ‘reasonable’ weather). I can’t report a description of wall-to-wall rain: your STORM category is overkill. We’ve had lousy weather here and associated floods for weeks - perhaps MONSOON is more appropriate…
I realise a few descriptions (eg. PARTLY or MOSTLY plus CLOUDY) are automatically suggested, plus manual changes like SNOW and HAZE can be altered. But in dismal northern winter climes like ours, please replace the euphemistic SHOWERS with good old British RAIN - and additional ‘APRIL SHOWERS’ when spring (I wish) arrives?
