7. What about the days when the sun doesn't shine or shines less like in winter season? Will the system still work?

As the system is dependent on sun light for the generation of electricity, lesser sun shine hours means lesser electricity generation. However, the battery provided with the system will act as a backup for power and this will cover you for your energy needs for some time provided if it is used properly without fully draining the power it has stored. Nepal has on average 4.5 hours of full sunshine everyday and this is enough for generation of electric power by the solar power system.
