Be aware to not hose them off when they have been exposed to sunlight for a certain amount of time. Solar panels become extremely hot and cold water will crack the glass panel.
Thanks for the reminder! The installer also warned me about this.
Yup, first thing I n the morning is usually best.
Water your panels like your garden
Never lived anywhere that can get cold water from a hose tap when it was hot outside. Rain water is always colder
