Solar Module

There are selected Indian firms which are set to produce wafers and ingots in India in the coming few months/years. Companies like Adani Group and Waaree have already announced their plans to produce wafers and ingots. Few companies like Waaree Energies won the PLI award of the government to produce wafers and ingots in India. On the other hand, companies like Premier Energies and Emmvee Group have also announced producing wafers and ingots in the country.

While cleaning solar modules with water first thing you should do is to use soft bristle cleaner or dedicated solar panel cleaning brushes. You need to also ensure that you do not use excessive water pressure. Excess water pressure can damage your solar panels leading to the development of microcracks. The maximum pressure that can be used for solar panel cleaning is 35 bars. You should also try to use soft water for cleaning solar modules.

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:
