Why is the Lighting Time Shorter than What is Stated in the Manual?
You need to make sure that the Solar Power Station/Module is directly facing the Sun during the day. Make sure that there are no branches, trees or shrubs covering the module. Only when the battery is fully charged the light lasts as estimated in the Manual. When you first use the lighting unit. Make sure you charge the battery to their full capacity which can be achieved after 4 days of full sunlight. Over time, lighting times may be lowered depending on the amount of charges they have had. It is recommended that making sure that the solar Power Station Module Surface is always clean.
