RE: Is Solar Power the Solution to the World’s energy Demand? Let’s have a look at solar PV system and how you can install one

in #steemstem • 7 years ago

But is there an alternative (like hybrid cars) in case the 🌞 doesn’t appear for a certain time?

Sort:  

Yes there is an option of an hybrid system even for household. This ensures that the backup(battery) is charged from the main power source even during cloudy days or at night. So allows the user two charging options vis: Sun and main supply.
Thanks for your comment and perusa
