How to Calculate Solar Price Per Watt?

Calculating solar price per watt is a simple process. Simply divide the total cost of the solar panel/solar system by the total system wattage. If your system is in kW, multiply it by 1000 to convert it into wattage and then divide the cost of the system. [1kW = 1000 Watts].

Solar Price/Watt = Total Cost of the System/Capacity of Solar System (in watt)

All solar brands have their own prices due to different solar manufacturing techniques and quality of materials. Therefore, reputed solar brands like Tata Solar, Luminous Solar and Havells Solar will provide you solar panels at around Rs.27 per watt, while other genuine solar brands like Adani Solar, Vikram Solar and Waaree Solar cost around Rs.22 per watt.The price per watt will allow you to compare solar quotes from various solar brands or installation companies.
