    Thanks. Can you please share the solar policies available in Noida for residential customers?

    Just a query : In the example above, monthly units consumed is 700 units, given the sanctioned load be 80% in Delhi, we can go for system size that can contribute 560 units. Considering solar radiation being 4 units per day, the system size comes out to be 1.4 KW – how have you calculated 1.1 KW, and 140 units from that?

      Hi Varsha,

      Thanks for writing in. Just to give you a brief insight, we use different algorithms to propose a suitable system design for consumers. Sanctioned load is not the only factor that we consider. We also consider users consumption pattern. The generation data shared in the article is for an actual user in Delhi.

    I have a roof of1000sqft. In those area how much kilowatt or units will produce per day.

      Hi Ashwini,

      Generation depends upon a number of factors such as the type of roof, place of installation, the height of the structure, shading pattern on the roof etc. Precise information can be given only post a thorough site assessment. However, if you just are looking for an estimated number, for a 1000 sq ft shadow-free area, a system of about 9kW can be installed. if you are in Delhi/NCR region, and are looking to go solar, you can register your rooftop with us at: itsmysun.com/register-your-rooftop-for-solar for a site survey.

    Can you please shed light on effect of smog on solar panels? what is the drop in output in winters duw to smog? Will the PM2.5 and PM10 particles hamper panels efficiency permanently? Also, how immune are solar panels to hailstorm?

      Thank you for your question Vikram. From the desks of our experts:

      “Smog will reduce the output of solar panel as the diffuse component of solar light will increase as compared to direct sunlight. The magnitude of reduction is dependent on the intensity of smog.

      PM2.5 and PM10 particles do not hamper panel efficiency permanently.

      Solar panels are quite immune to hailstorm. One of the tests in IEC 61215 is hail test in which ice balls of 1 inch diameter are hurled at the panel at high velocity and glass shall not break. Normally, tempered glass is used which is quite strong to take such impacts.”
