Technical FAQs 4

How many solar panels are needed for a 1 HP motor?

The number of solar panels needed for a 1 HP motor depends on the phase type, solar panel watts, and age of the pump. A brand new RPS 1 HP, three-phase pump utilizes twelve 100W panels, a total of 1200W. You could potentially use larger solar panels like 300W, meaning fewer overall panels but about the same square footage.

How much power does a 1.5 hp motor use?

Before delving into the solar panel requirements, it is essential to understand the power consumption of a 1.5 HP motor. One horsepower is approximately equal to 745.7 watts. Therefore, a 1.5 HP motor would require approximately 1,118.55 watts (1.5 x 745.7) of power to operate at full load.

How much power does a solar panel need in India?

Actual Power Required = 1,118.55 watts ÷ 0.8 = 1,398.19 watts Solar panels are available in various sizes and power ratings. In India, the most common solar panels have a power output ranging from 250 watts to 400 watts. For this calculation, let's consider a 330-watt solar panel, which is a widely available option in the Indian market.

How many kW is a 20 watt solar panel?

To calculate the required solar panel output, multiply the desired output by a buffer (usually 1.2 to 1.5). For example, with a 20% buffer, a 20 watt solar panel would provide 7.2 kW of power.
