How Many Solar Panels Need For 1 Fridge And 1 Washing Machine
Refrigerators and washing machines have started being used in normal homes today and that is why the electricity bill of our house has started coming much higher than before. We can easily run lights and fans in our house with the help of inverters and solar panels, but to run fridge and washing machine, we need two battery inverters.
That’s why not everyone knows which inverter will be right for them and how many solar panels they will be able to run the load of their house. So before running anything on solar panel you have to find out how much electricity that load uses.

How Many Solar Panels Need For 1 Fridge And 1 Washing Machine
So if you also want to know how many solar panels will be required to run a fridge and a washing machine on solar panels, then first of all find out how much electricity your fridge uses in 24 hours. And then find out that when you run the washing machine, how much electricity has been consumed for as long as that washing machine runs.
For example, let us assume that you have a normal 200 liter fridge and running it for 24 hours consumes about 2 UNITS of electricity. On the other hand, we don’t run the washing machine for 24 hours, that’s why its power consumption is usually less, that’s why if you run the washing machine for say 1 hour, it will consume about 0.5 units of power.
But if you run more than 1 hour, then you can estimate accordingly and at most we assume 1 UNIT power consumption, then the total power consumption of a fridge and a washing machine will be around 3 UNITS.
How Many solar Panels Needed
Now you need so many solar panels that you can easily make at least 3 units in 1 day. And if you want your battery to be charged by the solar panel during the day, then for that you will need at least 1 unit of electricity. So in total now you will need 4 units of electricity.
A 1 kW solar panel can generate about 4-5 units of electricity in a day, so you can use 3 solar panels of 330w to run a refrigerator and a washing machine, so that your battery will be easily charged during the day.
1kw Solar Panel Price
If you already have an old inverter and battery and want to install solar panels on it, then the cost of installing 1 kilowatt solar panels has been explained in detail below.
If you take polycrystalline solar panels of 1 kW, you will get them for around ₹ 30000. And if you take half cut solar panels on 1 kW mono, then you will get them for around ₹ 35000.
But to install solar panels on old inverters and batteries, you will also need a solar charge controller. If you take a solar charge controller of PWM technology, then you will get it for about ₹ 3000, with the help of which you can easily apply 1 kW of solar water on a battery.
If you want to get a solar charge controller of MPPT technology, then you will get it for about ₹ 6000, with the help of which you can easily install 1 kilowatt solar panels on two batteries.
Apart from solar panel and solar charge controller, the cost of your stand and wire will also come, it will cost around ₹ 5000, so the total cost of installing 1 kilowatt solar panel will be around ₹ 38000.
