    Usually in a residential rooftop project, a 3 Kw rooftop solar can ideally generate upto 10-12 units per day. The daily generations are usually dependent on the local weather.

    Usually in a residential rooftop project, a 3 Kw rooftop solar can ideally generate upto 10-12 units per day. The daily generations are usually dependent on the local weather. Usually when there is good sunlight throughout the day, you can get the best generation (if your solar panels are clean). During clouds, rains, the generations reduces. So a system which can generate around 12 Kw per day can also generate 5 kw or 7 Kw during clouds/rains. The generation also varies season to season, depending on the quality of sunlight and availaility of sunlight.

    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 check the health of your solar system, you can monitor it onsite with the digital displays given in the solar inverter. You can also also remotely monitor it through your concerned mobile application as recommended by your solar inverter company. For this you need to connect your solar inverter wRead more

If I use solar panels with the same wattage, will there be a difference in energy production between TOPCon and mono PERC technologies?

    Team of Solar Faqs | Answer on May 22, 2025 at 5:01 pm

    Even for the same wattage (Wp), TOPCon-based solar panels can perform better (or proudce more solar power). This is due to the better efficient solar cells used and lower degradation levels. On an average it is said that TOPCon-based modules can produce 5% extra generation than mono-perc based solarRead more

They can be used on really large commercial rooftops. Not on residential rooftops, as they would not be cost effective.

    This might be a little surprising, but solar generation doesn;t have much to do with how hot the weather is. Yes, summer days when it’s not cloudy are a great time to see solar kick in strongly,. but extreme heat is not good for generation as well.

    This is because solar panels generate electricity thanks to the flow of electrons that are stimulated by light falling on the cell. Most panels available today are tested for optimum operations between 15 to 35 or even 40 degrees centigrade.

    When temperatures spike, these electrons can bounce around too much and too fast, reducing voltage, or the amount of electricity generated.

    Thus, for every rise in temperature beyond 38 degrees or so, efficiency can come down by 0.5%. At 45 degrees, you could be looking at a 3-4% drop in efficiency therefore.
    Excessive heat can even lead to malfunctions of other parts in the system.
