The number of 400-watt solar panels you need depends on the size of your home and how much electricity you consume. Here’s how to calculate: Small Home (1-2 people): Generally, a 400W solar panel system will be enough for a small home that uses about 6-8 kWh per day. You would need approximately 5-6 panels.
The area of a 400W solar panel is around 2.2 square metres. It is a slightly larger size than the 300W panel and is suitable for small commercial applications as well as small-scale residential applications. It is a good size for those that need a larger system, but not too big for their rooftop.
The size of solar panels varies depending on their wattage and manufacturer. However, most standard solar panels for residential use range from 250-watt to 400-watt, with larger solar pv panel sizes providing higher energy output.
On average, most locations get about 4–5 hours of direct sunlight per day. Example Calculation: A 400-watt solar panel producing 400 watts per hour for 4 hours will generate 1.6 kWh (400W x 4 hours = 1600Wh = 1.6 kWh). This means, in ideal conditions, a 400-watt solar panel can generate around 1.6 kWh per day.
