As per title. We have a 330w panel but I’m yet to see more than 220w in direct midsummer sun on one of the hottest days. This is as reported by the Clayton app so idk if that could be misreporting but I don’t expect so. Not sure how close to max we should be expecting?
 
normally 50% to 80% of STC rated value. (Standard Test Conditions of 1kw per meter squared)

some panel may get you higher - Renogy are good for that.

the problem is as the panel get HOT the performance drops off.

so expect 50-80%

+++++++

assuming the charger is in BULK charge mode and the power has somewhere to go.

a 500W panel will show 1W if the battery is charged.
