1. Average kWh per person per day
For different families, the average number of kilowatt hours per person per day is different, this data is subject to the number of electrical appliances per person, personal habits and local electricity prices constraints, for a normal family, the average number of kilowatt hours per person per day is probably between 10kWh-30kWh.
To calculate the average number of kWh per person in your family you need to know the total power consumption in your home, you can find a energy meter in your home to find this value, assuming that the meter in your home shows that your home monthly power consumption of 1350kWh, if you have four people in the family, then the average number of kWh per person per day in your home can be calculated by the following formula, namely
Average kWh per person per day = monthly electricity consumption / family size / 30
Substituting the data into the above formula gives you an average kWh per person per day of 15kWh. Of course, this is only an average value, so this calculation does not reflect the real electricity consumption of each person, and you need to calculate the electricity consumption of each person individually if you want to know the real electricity consumption of each person.
2. What is the purpose of calculating the average kWh per person per day in your household?
First of all, calculating the average kWh per person per day in your household will help you to have a rough idea of your household’s electricity consumption, and then you can rationally plan everyone’s electricity consumption to avoid unnecessary wastage, which not only saves you a large amount of money on your electricity bill, but also reduces your household’s carbon emission, so calculating the average kWh per person per day in your household has an important role to play.
3. Is there any way to reduce your household’s electricity bill?
You can reduce your household’s electricity bill by using lower power appliances or by generating electricity. For example, if a portable air-conditioner running at 1500Watt and 2000Watt runs for 300 hours, the 1500Watt portable air-conditioner uses 150kWh less electricity than the 2000Watt portable air-conditioner, so it is clear that using appliances running at lower wattage is a good way to save on your home electricity bill.
Secondly, the use of solar panel power generation equipment is also a good choice, this power generation equipment is the use of free solar energy, and solar panels themselves do not cost a lot, according to the relevant data show that a 5kW solar energy system is probably only about 2500 $, to know a 5kW solar energy system in an average of 5 hours per day under the peak hours of sunshine, a month can produce about With an average of 5 hours of peak sunlight per day, a 5kW solar system can produce roughly 750kWh of electricity in a month, so it’s clear that solar panels can be a great addition to your life.
Of course, if your home’s monthly power consumption reaches 1,000kWh, and you need to build a solar system that can generate 1,000kWh, you can use the following calculation formula, namely
Wattage of photovoltaic panels = Monthly electricity consumption / 30 / Peak sunshine hours / Conversion efficiency of the solar system
Assuming that you are using a grid-connected solar system (with a conversion efficiency of 95%), and that you are located in an area where the average daily peak sunshine duration is 5 hours, you can substitute the above formula to get the total wattage of your photovoltaic panels to be 7kW, i.e., you will probably need a solar energy system that is 7kW in size.
4. Summary
By knowing the average kWh per person per day, you can optimize your home’s power system and reduce your home’s electricity consumption, which is very important for you in the long run. Of course, you can choose to install a suitable solar system for your home, so that your home can be supplied with a constant supply of electricity, and if you have any ideas about this, you can consult with a solar equipment supplier, who can offer you a suitable solution. You can consult a solar equipment supplier if you have any ideas about this, and they will provide you with a suitable program.
