What Size Solar Generator Do I Need? For House, Camping, Camper and More
Table of Contents
A solar generator is a highly convenient and versatile power source. You can use one to access power while on the go or as a backup source of energy for your home. Before buying one, you might be asking yourself, what size solar generator do I need?

This is certainly an important question. Buying the right size solar generator will ensure that you have an optimal source of power without paying more for one than you have to.

This is because a “solar generator” can technically refer to a solar solution that combines two (or more) components. A Jackery Solar Generator consists of:

1. The solar panels – which collect the solar energy from direct sunlight.

2. The power station – which stores the electrical power converted by the solar panels.

In this article, we will help you figure out what size power station is most suitable for your solar generator goals. Keep reading to learn how to calculate the right power station size, along with other information about solar generators, so that you make the best choice.

How Power Stations Are Sized

Power stations are typically sized in watts (W). This is a measure of power that’s used to calculate the rate of energy transfer. But what you really need to know is that the greater watts a power station has, the more power it can provide you in a single charge.
That being said, there are different watt measurements to pay attention to when deciding on a power station.

Continuous Power

The first measurement is usually called continuous power. This is the amount of power that a power station can provide consistently.

Peak Power

The second measurement is usually called peak power. This is the maximum amount of power that a power station can provide in a short burst.

Continuous Power vs. Peak Power (An Example)

Here’s an example. Think of when you turn on your air conditioner. It needs a quick burst of power to get started. That’s peak power. But the amount of power needed to continuously run the AC unit is generally lower. That’s continuous power.

Some appliances, such as refrigerators, need a burst of 3-7 times their normal power needs to get started. Keep in mind, your power station needs to be able to accommodate this peak power requirement to run the appliance. So, if you are looking for a solar generator to run a refrigerator, simply meeting the continuous power requirements won’t be enough.

Continuous power will likely be the more impactful number for you to think about. It’s what tells you how much power you will get from a single charge of your power station under normal conditions.

How to Calculate Your Optimal Power Station Capacity in 3 Steps

Jackery manufactures power stations to meet a wide variety of power consumption needs. Our products range from 99Wh of capacity to as high as 24,000Wh of capacity. To figure out which Jackery product offers the right power capabilities for the appliances you want to charge, you’ll need to perform the following calculations. Here's the step-by-step to calculate the right size power station:

Step 1: Select Tools/Appliances You Want to Power With Your Power Station

The first part of picking the right power station for your needs is understanding what those needs are. This means selecting the specific devices that you want to power with your solar generator and setting a rough estimation of how long you’d like for its power station to provide that power.

Here are some common devices that people power with solar generators:

  • Laptops and PCs
  • Phone chargers
  • Coffee maker
  • Hairdryers
  • Air conditioners
  • Water heater
  • Blender

Note: You'll need to list the appliances that you are planning to use at the same time.

Step 2: Note Down Their Running & Starting Wattage

Once you know what you want to power, it’s time to figure out their starting and running wattage. For this, you can either check the user manual or the appliance wattage chart. Sometimes, the wattage consumption is also printed on the appliance itself. But if you only see a measurement for amps and volts, you can multiply these numbers to get appliance wattage consumption.

Shown here:

Step 3: Calculate the Surge Wattage of the Solar Generator

Once you've listed the running and starting wattage of the appliances you want to charge simultaneously with the power station, the next step is to calculate the surge wattage by adding the total running wattage and the highest starting wattage of the appliance. The number obtained will represent the surge wattage that the solar generator should be capable of supplying power to all these appliances.

Can a Solar Generator Power a House?

Note that unless you purchase a large Jackery Solar Generator (such as Solar Generator 2000 Plus with an portable power station with 1264Wh capacity), you likely won’t be able to power most appliances in your house for multiple hours with a solar powered generator.

If you find that the answer you got in Step 3 is higher than almost every power station you look at, then you may need to go back and reassess what you really need to power with it. If you can lower yourself down to just the essentials, then you will find a solar generator that works for you without having to break your budget to buy it.

Jackery Solar Generators and Suggested Usage Scenarios

Running out of power can never be fun. That is why Jackery has designed different sizes and capacities of solar generators. Whether you are looking for a home backup solution or a power pack for your outdoor adventure, Jackery offers an impressive product line for every scenario.

The Benefits of Buying a Portable Solar Generator

Portable solar generators are a dynamic backup power option. You can use them both in your home and when you’re on the go. They’re purposefully made smaller than dedicated home backup solar generators to offer this flexibility.

As they feature a power station that you charge with portable solar panels, you essentially plug the portable solar panels into the power station until it’s charged. Then you can use the power that you’ve created on almost any appliance or electronic device that you want.

Many people purchase portable solar generators to get access to clean power while enjoying the outdoors. Then, as an added benefit, they can use the generator as a backup source of energy for their homes whenever they need one. It’s this versatility that’s made portable solar generators so popular.
