Solar Module

Yes. The solar panel technology namely-polycrystalline, mono-PERC and TOPCon can produce different quantum of power per day due to improved quality despite having the same wattages. So pick the latest technology to ensure the peak generation from your rooftop system. Out of all these, TOPCon produces highest solar generation, followed by mono-PERC and polycrtalline.

To estimate how much electricity your solar system can generate in a day, you need a few key pieces of information:

The total DC capacity of your solar system (in kW)

The average number of peak sunlight hours in your area (also called solar irradiation)

Just multiply your system size by the peak sunlight hours to get the theoretical daily generation.
For example, if you have a 3 kW system and your area gets 5 hours of good sunlight daily, then:

3 kW × 5 hours = 15 units (kWh) per day (theoretical)

However, in real-world conditions, solar systems usually operate at about 78% to 80% efficiency due to energy losses (from wiring, inverter, dust on panels, etc.).

So, you can expect around 20% less generation than the theoretical figure.
Using the example above, the actual generation would be about:

It is likely that cyclone and high wind can damage your solar project. However, strong solar structures with robust technology can prevent such damage. So it is very important that you do not go for weak, slick solar structures and trust modern and robust technology which are resilient to extreme weather events

Now, MNRE has made this process more convenient. Now the PM Surya Ghar Portal allows you to check details of each vendor like the number of solar projects they have installed. You can also find out which companies have installed the highest number of solar panels in your area. You just need to go the portal, go to the empanelled vendors and feed in your local discom name and your city, and the portal will give you the details?
