What happens if there is no sunshine (i.e during cloudy period)?
Before you buy a solar system you are advised to consult a competent technician, who will specify the sizes of required equipment that can meet your energy needs. If this is done, a well designed system should have enough storage of charge in batteries that can fulfill your electricity needs during the cloudy period. That means performance of your system will not be affected during this period. Example: In tropical countries, a system can be specified to deliver electricity services for three consecutive days in absence of sun shine. The exact number of days will depend on your geographical location and weather condition.
