5kw solar system applications

If you want to install a 5KW solar system, you should know if it can support your household loads and how much power it can produce one day.

How much power does a 5kw solar system produce per day?

The 5kw solar system is a system that converts solar energy from the sun into electricity taking advantage of the photoelectric effect. For example, 16 solar panels with each unit 330W can make the power of 5280W or 5kw in reasonable sunlight. The more solar panels, the more power they produce.

How many kWh does a 5kw solar system produce?

A 5kw solar system will produce around 20kw for one day to support the applications.

In fact, a 5kW solar system will produce 5000 watts (5kw) DC power per hour during peak periods. Please note that install your solar panels facing the south direction to make the most use of the solar energy.

In general, the normal hours of sunlight are 8 am to 5 pm with the peak time being 10 am – 2 pm, which is the time that solar panels can produce the most solar energy.

Look at this application of a hybrid 5kw inverter, which efficiency is up to 97.5%. If you have at least 5 hours of lights a day, the 5kw solar system could produce an estimated 350 to 850-kilowatt hours (kWh) of AC power per month.

5kw hybrid inverter converts the DC power generated by PV panels into AC power to the load, and the rest will be stored in the battery for a backup system, excessive power will be feedback into the grid.

How many solar panels do I need for a 5kw inverter?

If you have installed a 5kw hybrid inverter, you will get 2 MPPT(Maximum Power Point Tracking), and each MPPT voltage range 120-500V.d.c and each MPPT max. input current 12.5A. For a 5KW hybrid inverter, its AC input/output and UPS output nominal power is 5kw, which should be no less than your home load because when the grid is in an outage the UPS can afford all your household load on work together. Therefore the power of the solar panels should be not less than 5kw for there is the energy expended during the conversion.

the number of the solar panels≈ the power of your home load/ the rated  power of a single solar panel

In this way, you probably know how many solar panels you need. Of course, it can be more than the result of this algorithm, because this is the result obtained in the case of self-consumption use. If you want to feed the surplus electricity back to the grid and get government subsidies to reduce bills, you can install more panels, but remember that the total power should not exceed the max input power of the solar inverter i.e. 8000w. That is the home load< the power of total solar panels <8000w.
