Can Solar Run a Washing Machine? (Philippines)
TL;DR
A washing machine is one of the easiest appliances to run on solar. A typical Philippine load uses well under 1 kWh, costing a few pesos, and any grid-tied system can cover it if you wash during daylight. The expensive parts are heated water and electric drying, not the washing itself.
A washing machine is one of the easiest appliances to run on solar. A typical Philippine cold-wash cycle uses roughly 0.3-0.8 kWh — a few pesos at 2026 rates — and any grid-tied system, down to 1kW, generates several times that on an average day.
The real answer to “can solar run my washing machine” is: yes, easily, and the question you should actually be asking is about the dryer.
What laundry actually costs
At a 2026 Meralco rate of roughly ₱14/kWh:
| Appliance | Typical draw | Energy per use | Cost |
|---|---|---|---|
| Washing machine, cold cycle | 300-500W while running | 0.3-0.8 kWh | ₱4-11 per load |
| Washing machine, heated cycle | 1,500-2,500W during heating | 1.5-3 kWh | ₱21-42 per load |
| Electric clothes dryer | 2,000-3,000W | 2-4 kWh per load | ₱28-56 per load |
| Clothesline | 0W | 0 | Free |
Three loads a week on cold wash is somewhere around ₱15-30 a month. That is noise against a bill dominated by aircon and the refrigerator — see the full picture in our appliance electricity cost guide.
Why timing matters more than capacity
Laundry is a shiftable load, and that is what makes it so well suited to solar. You choose when it runs.
Under net metering, power you export earns a credit of roughly ₱5-7/kWh, while power you buy costs about ₱14-15/kWh. So a wash cycle run at 11am, directly off your own generation, effectively saves you the full retail rate. The same cycle run at 9pm is bought from the grid at retail while your daytime surplus was sold at half that.
Nothing about this needs a battery. It needs the machine to run between roughly 9am and 3pm. If your machine has a delay-start timer, that is the single most useful feature it has for a solar household.
What if I want to run it at night anyway?
Then it comes off the grid, or off storage if you have it. A wash cycle is a small enough load that a battery handles it comfortably — under 1 kWh out of a 5kWh pack.
But laundry is a poor reason to buy storage. If you are weighing a battery, the case rests on brownout resilience and evening aircon, not on being able to wash clothes after dark. Our how to size a solar battery guide explains why high-wattage, short-duration and easily-shifted appliances should be left out of battery sizing.
The dryer is the real question
An electric clothes dryer draws 2,000-3,000W while running, which is comparable to an aircon and an order of magnitude above the washer. Two or three loads a week can add ₱250-650 a month.
Running a dryer on solar is possible but it dominates a small array. A 2kW system producing about 8 kWh a day would spend a third of a good day’s generation on two dryer loads. On a 5kW system it is comfortable, provided it runs at midday.
In Philippine conditions, though, line drying is free, effective for most of the year, and the obvious default. The dryer earns its place during long rainy stretches, and if that is when you need it most, note that it is also when your solar output is lowest.
Practical takeaways
- Wash cold, during daylight. That is the entire optimisation, and it costs nothing to adopt.
- Use the delay timer to land cycles at midday if you are out.
- Do not size your system around laundry. Size it around aircon and the refrigerator — what size solar system for my bill.
- Line dry when you can. No solar system beats free.
If you are working through appliances one at a time, the ones that genuinely shape a Philippine solar build are covered in solar for refrigerator and solar panels for aircon.
Frequently asked questions
How much electricity does a washing machine use in the Philippines?
A typical cold-wash cycle uses roughly 0.3-0.8 kWh, which at 2026 rates is only a few pesos per load. Most of that goes to the motor and the pump. Washing is genuinely cheap electricity.
Can a small solar system run a washing machine?
Yes. Even a 1kW array produces around 4 kWh on an average day, several times what a wash cycle needs. The constraint is timing rather than capacity — run it while the sun is up and it costs you nothing.
Does a washing machine need a battery to run on solar?
Not if you wash during daylight, which is the whole trick. Washing is a shiftable load, so scheduling it for midday means it runs directly off generation at full retail value rather than off exported credit.
What about a washer with a built-in heater?
That changes the picture completely. Heating water is the expensive part of laundry anywhere, and a hot cycle can use several times the electricity of a cold one. In Philippine conditions cold washing is normal and effective, so this is easy to avoid.
Can solar run an electric clothes dryer?
It can, but the dryer is a serious load — typically 2,000-3,000W while running, comparable to an aircon. A small system will be fully occupied by it. Line drying costs nothing and is the obvious alternative in this climate.
Should I size my solar system around laundry?
No. Laundry is too small a share of a Philippine bill to drive system sizing. Size to your overall consumption, aircon and refrigeration first, and laundry falls out as a rounding error.
