Daily maintenance is not required. The only maintenance required is when a component is reaching the end of its life cycle..The lifetime of each component can vary depending on environmental conditions..For example:
Solar panels last approximately 30
years Batteries last approximately 5-7 years
LED fixtures last approximately 50k-100k hours
Drivers and other electrical components vary from 5 to 15 years
It is important to know that systems are designed with a power factor of 10-30% to account for dirt and snow build-up..If certain environmental conditions are experienced at the project site, it is important to tell the solar designer so that these factors can be incorporated into the system design.
