My question is product-based I want to make smart solar panel so I need some advice Normally solar panel system consists of a solar plate and inverter or batteries. So the solar panel will be developed easily but it is a bit difficult to make a smart solar panel.

I'm sure you must have built or seen smart solar systems If you want to make a smart solar panel for a home application, then which features can you add to it?

 

What do yo want your "smart" solar panel system do that an ordinary one will not? Once I understand your requirements I may be able to help.

The smart solar panel should tell how much per cent charge the inverter is? If the inverter is not charged, the user should get an alert message And home devices must be powered by government electricity? May show supply voltage and current?

 

So you want solar panels to charge a battery and that drives an inverter to run home appliances unless the batteries are discharged then you use mains electricity?

All standard off the shelf stuff. Google "on-grid solar storage"

Do you want to design the hardware and software to produce one your own? What is your skill level in electronic hardware design and software development ? Do you have any experience with solar power control?
