Delhi is a city of contrasts—scorching summers, mild winters, and, let's not forget, significant air pollution. While you might think abundant sunlight is perfect for solar panels, there's more to the story! Let's dive into the details together.

Sunny Days Are Blessings For Solar

- Delhi receives abundant sunshine throughout most of the year.
- This is beneficial for solar panels, which convert sunlight directly into electricity.
- Solar panels in Delhi can reach a peak efficiency of 5 units/kW/Day during the tropical zone from April to September.

Heat Can Be a Challenge

- While sunlight is crucial, extremely high temperatures can slightly reduce solar panel output.
- Solar panels have a temperature coefficient, indicating their efficiency decreases as they become hotter.

Winter Woes? Not Quite

Sunshine Hours Matter More Than Temperature
- During Delhi's mild winters, there are fewer daylight hours.
- Despite this, solar panels can still capture sunlight and generate around 2.5 units/kW/Day from December to February.

The Smog Factor: A Partial Shade

Pollution Can Play a Role
- Delhi’s air quality can be a concern due to dust, smog, and particulate matter.
- These pollutants can act like partial shade, reducing the sunlight reaching the panels and impacting electricity generation.
- Proper chemical cleaning can help mitigate the effects of pollution.

Recap of Solar Benefits in Delhi:

  • Abundant sunshine for most of the year
  • Fewer day light hours in winters effects the generation
  • Chemical cleaning helps minimize the impact of pollution
  • Average daily generation in Delhi is around 4unit/kW/day
