Are you wondering if a 400 watt solar panel is enough to power your appliances? The answer is yes! A 400 watt solar panel can provide enough energy to run a small refrigerator (80 watts) or a DC refrigerator (170 watts). However, you'll need a battery to store the energy produced by the solar panel. On average, a 400-watt solar panel will generate between 1.6 kWh and 2.6 kWh of energy per day. This translates to between 250 and 340 watts of power per hour.
With this amount of energy, you can expect an average run time of 14.4 hours for an 80W refrigerator and 6.8 hours for a DC refrigerator in a day.So, if you're looking for an eco-friendly way to power your appliances, a 400 watt solar panel is a great option. Not only will it help you save money on your electricity bills, but it will also reduce your carbon footprint.
