How Many Batteries Do I Need for a 100 Watt Solar Panel
100-watt solar panels are conveniently sized and portable power systems. You can get clean and renewable energy from the sun without breaking the bank.
They work great in off-grid settings like RVs and power several smaller AC appliances.
100-watt solar panels are much smaller than most solar panels that are used in homes. Typically, 100-watt solar panels have size measurements of around 47 x 21.3 x 1.4 inches.
The best way to use your 100-watt solar panel is to hook it up to the right battery. Batteries store excess power to keep your electricity running on cloudy days and at night.
We are here to tell you all about batteries you may need for 100-watt solar panels. You will learn about the types of batteries, and what capacity battery you will need.
We also give you a rundown of the power output of a 100-watt solar panel, and other devices you may need to run your solar setup.
Batteries for 100 Watt Solar Panels
Your solar power installation needs additional devices like batteries, charge controllers, and inverters to function optimally.
Batteries are crucial for running 100-watt solar panels. Always remember to check your 100-watt solar panel specifications to make sure they are suitable for your purposes.
Does Your Solar Installation Need a Battery?
Portable solar systems that make use of 100-watt solar panels can be used on off-grid properties and RVs. If your solar system is at home, on the other hand, then electricity can be imported and exported from the grid when needed.
But without access to power lines, you need another way of storing energy. That is why off-grid solar systems need batteries to function.
Batteries save the excess electricity that solar panels produce during the day. Batteries do not allow electricity to waste and will keep your power running at night and on cloudy days.
What Capacity Battery Should You Get?
Batteries store excess electricity. The bigger the capacity of the battery, the more storage you get. But batteries also shouldn’t be too big.
If your battery capacity is expanded drastically, the capacity of your solar installation would also need to be expanded. Otherwise, it would take very long to charge the battery.
For a 100 watt solar panel, a 100 Ah 12V battery would work well.
Remember that your power input needs to roughly match your power output. A 100 Ah 12V battery provides around 50% usable storage.
That is why your battery should be able to store at least twice the daily output of your solar panel. As a general rule of thumb, your 100-watt solar panel can deliver 30 amp-hours per day to your battery with 5 – 9 hours of sun exposure.
This is where it becomes important to calculate your usual power usage and to assess your electricity needs.
How Many Batteries Do You Need?
If you use a 100 Ah 12V battery, you should be good to go with only one battery.
You may assess your power needs for your solar setup and find that you need a larger battery or two batteries.
Keep in mind that one 100Ah 12V battery will do the job with one 100 watt 12V solar panel. If you get a larger battery or more batteries, you will probably have to expand your solar array too.
Why? While one 100 watt solar panel can charge a 100Ah 12V battery with ease, it may take a very long time to charge larger batteries or more batteries. That is why you would need to expand your solar setup.
Types of Batteries
Solar setups usually use deep cycle batteries, because they are designed for prolonged and repeated cycles of charging and discharging.
Deep cycle batteries are used to store and distribute the energy generated by your solar panels. The higher the capacity of your battery, the more energy can be stored.
Deep-cycle batteries can be discharged completely without obtaining damage as easily as normal batteries.
Lead Acid Batteries
Lead-acid batteries are the most cost-effective energy storage option and are commonly used in RV solar setups.
You should not run your lead acid battery below 50% capacity. You should have a solar battery with the capacity to store twice the daily amount of your panel’s output.
If you want to sustain your battery to make it last long, avoid letting the battery drop under 50%.
Lithium-Ion Batteries
Lithium-ion batteries are much more expensive than lead-acid batteries and less common in RVs. These batteries have a longer lifespan and can store more energy than lead-acid batteries in a smaller space.
Lithium-ion batteries can be discharged almost completely. Your battery should have a storage capacity just a bit over the daily output of your solar panel.
Make sure you know how to install a 100-watt solar panel with lithium-ion batteries. Lithium-ion batteries tend to catch fire if it is not set up correctly.
Charging 12V Batteries With 100 Watt Solar Panel
You can charge 12V batteries with a 100-watt solar panel. The time this would take depends on the capacity of the battery and sunlight exposure.
A rough estimate would be that it can take between 10 – 14 hours to fully charge the battery.
For faster and more effective charging your solar panel should face the sun without obstacles in between.
How Much Power Does a 100 Watt Solar Panel Produce?
Watt-Hours
The output of a 100-watt solar panel depends on a few factors. The amount of sunlight and the angle of the solar installation will influence the output.
On a sunny summer day, your 100-watt solar panel may have an output of around 600 – 700 watt-hours over 24 hours.
In the winter and on overcast days the output may be as low as 100 watt-hours over 24 hours.
Amp-Hours
100-watt solar panels produce around 5 to 6 amps of power per peak sun hour. In direct sunlight, this would amount to around 30 amp-hours per day.
The ‘maximum current’ rating of a 100-watt solar panel is 5.5 – 6 amps. Solar panels produce a number of amps between 50 – 100% of the value of the maximum current rating, under normal conditions.
Devices That Can Run Off a 100 Watt Solar Panel
100-watt solar panels can run many home AC appliances that make your life easier when you are on the go. Here are some electricals that will run with a 100-watt solar panel.
- Ceiling fans.
- Lamps and lighting.
- Laptops.
- Wi-Fi Routers can be powered for a whole day.
- LED lights.
- Charge smartphones or tablets.
- Small LCD TV set.
- Cable box and satellite dish.
- Printers.
- Alarm clocks.
This will not work for appliances like larger air conditioners, refrigerators, microwaves, hairdryers, electric kettles, and large TV sets. If you want to run these appliances you would have to know how to connect 2 100 watt solar panels or more.
If you want to connect solar panels to expand your setup, you would need a lot of additional equipment – solar power mounting brackets, solar panel cables, and fuse holders are just a few.
You would also need to be clued up on what gauge wire for 100-watt solar panels are the most suitable before you can wire your setup.
Other Devices for Your Solar Setup
Solar Charge Controller
Solar charge controllers are portable devices that regulate the current and voltage of your solar setup.
They regulate power flow, charge batteries, and run electrical loads, and manage the flow of energy between your solar panels and batteries.
What size charge controller do I need for a 100-watt solar panel ? A safe bet would be to have a 10-amp charge controller for a 100W solar panel with a 12V battery bank.
Inverter
Inverters work to convert the electricity flowing from your battery from direct current (DC) into alternating current (AC).
What size inverter do I need for a 100-watt solar panel ? A rule of thumb is that you have to choose a model of inverter with a capacity larger than the true power output you would need.
The capacity of the inverter needs to be 10% to 20% higher than your largest power load.
You would need a 12v DC to 220v AC, 200W inverter.

About 100 W solar panels and solar kits
A 100-watt (W) solar panel is a photovoltaic (PV) module that has a power rating, or wattage, of 100 W. This means that the panel can produce 100 W of DC power under ideal conditions.
In terms of real-world output, you may be able to hit 100 W when it’s very sunny out, but the rest of the time output will likely be lower than that.
A 100 W solar panel kit comes with all the components you need for a small solar power system. Exact contents can vary from kit to kit, but they typically include a solar panel, charge controller for battery charging, power inverter, wiring, and mounting brackets. Sometimes, compatible 12-volt battery packs are available as an add-on.
Solar panels come in a range of sizes and weights, but 100-watt panels are generally small and easy to handle. A typical 100 W solar panel, like this model from HQST, measures about 6.5 square feet (ft²) and weighs about 14 pounds.
If you want something lighter, consider a 100 W flexible solar panel; these only weigh 4 to 5 pounds each.
How much do 100-watt solar panels cost?
A standalone 100 W solar panel costs 100 to 200, depending on the brand.
A basic 100 W solar starter kit usually costs around 150, while a premium kit will have a price tag closer to 300. It’s rare for a battery to be included at this price point.
For a 100 W solar panel kit with a compatible portable battery, the price range is pretty wide: anywhere from 400 to 1,700.
Use these costs only as a guide; can vary depending on brand and features.

What can a 100 W kit run?
A 100 W panel connected to a deep cycle battery is ideal for running small devices like Wi-Fi routers and smartphone chargers.
Here’s how long you can expect to run different devices with a 100 W solar panel kit.
| Device(s) | Typical power usage | Run time |
| Four smartphone chargers | 20 W | All day |
| Three Wi-Fi routers | 18 W | All day |
| Two LED lights | 20 W | All day |
| Ceiling fan | 35 W | 14 hours |
| Laptop | 60 W | 8 hours |
Assuming 500 watt-hours of usable energy
A single 100-watt panel will struggle to power larger devices, or many devices running at the same. Your battery will either fail to handle the load or run out of juice very quickly.
If you need more power, consider expanding your system’s capacity with additional 100 W panels, or upgrading to something more powerful like a solar generator.
What is the energy output of a 100 W panel?
In terms of instantaneous output, a 100 W panel may be able to hit its maximum power output of 100 Watts of DC power when it’s very sunny out, but the rest of the time output will likely be lower than that.
It’s more useful to measure solar panel output over time using watt-hours (Wh). Over a day, a 100 W panel typically generates between 300 Wh and 600 Wh.
Location and weather determine output
The average output of a 100-watt solar panel differs from place to place due to varying latitude and climate conditions.
Panels are able to generate the most energy in locations that receive lots of sunlight. In Arizona, for instance, you’ll consistently see excellent power output – an average of 750 Wh per day.
At the other end of the spectrum, there’s Alaska. There, the long months of winter darkness mean average output drops to just 280 Wh a day.
As you’d expect, the average output you’ll see in all other states will fall somewhere between these two extremes. Here’s a map that indicates the average daily power output of a 100 W solar panel in each state.
Wh = Watt-hours. This map is an approximation of the energy output from a 100 W solar panel; there are variations by region within states.
You’ll also want to account for the impact of weather.
A 100-watt panel can potentially generate 800 Wh or more on long sunny days with cool temperatures. But, production could drop as low as 50 to 100 Wh on very cloudy days.
Do I need a battery with my 100 W panel?
Pairing your 100 W solar panel with a battery is generally a good idea. Although it will add to your costs, a battery will help you make full use of your solar panel’s potential.
Here’s why. Solar panels tend to produce the bulk of their power around midday, and you might not be able to use all that power right then. Unlike a home solar panel system, a 100 W panel can’t export to the grid, which means unused power will simply go to waste. The solution is to add a battery pack that can store excess power, making it available for you to use later when you need it.
Lead-acid battery
Although bulky, lead-acid batteries are an affordable way to add storage to a 100 W panel. You should pair a single 100 W panel with a 12-volt lead-acid battery with a capacity of around 1,200 Wh. Make sure to factor in depth of discharge – you shouldn’t use more than 50% of the energy stored within most lead-acid batteries.
Lithium batteries
Lithium batteries are lighter and more efficient than their lead-acid cousins. Another point of difference is that they can be discharged almost completely. Aim for storage that is able to hold slightly more than your solar panel’s typical daily output. An example of an appropriate lithium-ion battery is the Goal Zero Yeti 4; it has 396 watt-hours of storage capacity, so you should be able to fully charge it over a reasonably sunny day.
Can you power a home with 100 W solar panels?
You could if you wanted to, but it wouldn’t make financial sense.
Homes use a lot of energy, and they generally require a solar system sized between 5 kilowatts (kW) and 10 kW (that’s 5,000 to 10,000 W). You would need between 50 and 100 100-watt solar panels to make a solar system that size. It’s far more efficient and cost-effective to build a home solar panel system with residential solar panels that are 350 to 400 W each.
Calculate how many solar panels you need to power your specific home
Can you connect multiple 100 W panels together?
Yes, you have the option of ‘chaining’ solar panels together to increase the total output.
For instance, connecting two 100 W panels together in series or parallel will give you up to 200 W of usable power.
It’s extremely common for solar panels to be connected. Many RVs have three or four 100 W panels connected together in their setups. Home solar panel systems use the same method to connect 10 to 20 residential panels together.
However, before adding additional panels to your setup you’ll first want to make sure that your inverter and battery (if you’re using one) can handle the extra power input.
Our verdict on 100 W solar panels
If you haven’t used renewable energy, a 100 Watt (W) solar panel is a great way to dip your toes in the proverbial water.
While they come in many shapes and sizes, every 100 W panel will provide you with small but useful amounts of solar power. They’re most effective when paired with a battery, as this lets you store energy for later use. They’re a great way to charge up phones and tablets when you’re away from a power outlet, like during a camping trip.
Just remember that a 100 W solar panel is only meant to power two or three small devices; it’s not the right choice if you’re looking to power your entire home. For that, you’ll need a system that has at least 5,000 W (5 kW) of capacity that is built with residential panels that are 350 W to 400 W each. Such a system can offset up to 100% of your electric usage while also charging up a solar battery like the Tesla Powerwall.

How To Connect A Solar Panel Bought At Harbor Freight To A Jackery Explorer Power Station
Solar panels can be bought at a lot of different places nowadays, the popular hardware store Harbor Freight is one of those places.
A Harbor Freight solar panel is not compatible with a Jackery power station directly out of the box though since it requires additional adapters.
Related Product: Extend the cable between the solar panel and the power station with an SAE extension cable by iGreely (click to view on Amazon)
In this article I am going to tell you what these connectors are called, and how you go about connecting the two.
What You Need To Know
Before we get into the specifics, there are some things we need to know before we connect anything.
Solar Charge Controller
The job of a solar charge controller is to take the voltage and amperage generated by a solar panel and regulate it. Then it sends the regulated electricity off to the battery.
Portable power stations have built-in solar charge controllers so you can connect solar panels directly to them.
The Jackery Explorer is not going to charge if you use two charge controllers. Therefore, we should not buy a solar panel that has an external solar charge controller.
If you have already bought a panel that included a solar charge controller, you can (hopefully) simply not use it. If it’s hardwired to the solar panel you’re going to have to either bypass it, or buy a different panel.
Input Ratings
Not all solar charge controllers are the same. They have different input ratings, meaning that they accept different voltages and amperages.
The input ratings can usually be found in the manual of the power station, or by the port on the power station.
Most Jackery Explorer power stations can handle voltages between 12-30V, and a typical 100W 12V solar panel like the most popular one from Harbor Freight outputs around 18V which makes it compatible.
If you combine two or more panels, you’re going to increase either the voltage or the amperage but we will get to that later on.
While it’s OK to exceed the amperage to a certain point, you should never exceed the max input voltage.
The Harbor Freight Solar Panels – What Connectors Do They Use?
Most solar panels sold by Harbor Freight today use SAE connectors. This is a two-conductor DC connector that is easy and quick to connect/disconnect, which makes it a great connector for a solar panel.
SAE connectors have one male pin and one female pin. One is positive and one is negative, but which is which depends on the wiring and adapters used.
The panels from Harbor Freight that use SAE connectors I have looked at have a positive female pin and a negative male pin. This is important when we search for the right adapter.
A positive wire is often red and a negative wire black. The wires are not different from one another other than the color, which is only made this way to make it easier to connect and follow the wire.
You might find a connector with a small “” or “-” on it, with a cable color that makes it look like it’s the opposite of what the connector says.
This is nothing to worry about, as long as you can follow the wire and make sure that the positive output ends up with a positive input.
The Jackery Explorer Input And The Adapter You Need
The input on Jackery Explorer power stations is called an 8mm connector. This is a round connector which also has a positive and a negative part to it.
Since we know that the SAE connector has a positive female pin and a negative male pin, we need an adapter that has the opposite.
This adapter includes what is called an SAE reverse polarity adapter, which will reverse the positive and negative. You do not need to use that to connect the panel to an Explorer power station.
Note that if you have the newer Explorer 1500 (click to view on Amazon), you are going to have to use the adapter included by Jackery to connect the adapter above to the power station.
That’s because Jackery has created a proprietary 8mm input for the Explorer 1500, and even though it’s called an 8mm input it’s slightly different from the regular 8mm connector used by other manufacturers.
When you have the adapter, you simply connect the solar panel to the adapter, then connect it to the power station.
Combining Two Or Panels To Increase The Charging Speed
It’s possible to combine two or more panels to charge the battery faster, but it’s not always worth doing so.
Since the charge controller in the power station decides how many watts it’s going to use to charge the battery, it’s good to know these limitations before spending money on more panels.
For example, the Explorer 160, 240, 300, and 500 max out at around 50-80 watts depending on model. The larger Explorer 1000 max out at 127W, and the even larger 1500 at 300W.
A 100W 12V solar panel will generate around 70-80W in sunny conditions.
It’s not always perfectly sunny though, and if you’re going to use the panels where it’s often cloudy it might be more worth it to buy an extra panel or two.
To combine two Harbor Freight panels for the Explorer power stations, you need an adapter like this by SolarEnz (click to view on Amazon).
This adapter also includes the SAE reverse polarity adapters, which you might need to ensure that positive goes to positive and negative to negative.
When you combine panels in parallel like this it’s very important that you have made sure that all wiring used can handle the amperage. That includes these adapters and extension cables.
Extension Cables
I recommend using SAE extension cables that come with caps to protect the connectors while not in use. These dust caps keep dirt, debris, and moisture out.
The thicker the cable the better, so look for the lowest gauge you can find and make sure it can handle the total amperage of your panel(s).
I like and recommend the iGreely SAE extension cables (click to view on Amazon). They come in different lengths and are compatible with the adapters I have linked to above.
While you can combine two shorter extension cables I suggest getting a long one instead. The more connections, the higher the voltage drop, which will decrease the total output to the power station.
Frequently Asked Questions
I’m not sure whether the polarity is correct or not!
You can use a multimeter to check the polarity of the wires. This is also helpful when troubleshooting a setup that’s not working correctly.
A digital multimeter like this one by Kaiweets (click to view on Amazon) works, just set it to four o’clock (20 by V DC) and stick the red test lead in the supposedly positive SAE connector on the panel/adapter.
Then do the same with the black test lead. If it shows a positive voltage on the little screen, you know it’s wired correctly. You can test it the opposite way to understand what it looks like if the polarity is reversed.
How long will it take to charge my Explorer power station?
It depends on how big the power station is in watt-hours. A 100W panel will generate around 70-80W, but if your power station has a max input of 65W you need to do a calculation based on that.
For example, the latest Explorer 500 (click to view on Amazon) has a battery capacity of 518Wh and maxes out at around 70W.
The way to calculate how long it would take to charge the Explorer 500 with a 100W solar panel is then: 518/70=7.4 hours.
We also need to consider the fact that the charge controller will start out charging the battery fast, then slow down as it is getting closer to a full charge.
Therefore, I would add another hour or two to the estimate to get a more accurate number, resulting in 8-9 hours for a full charge.
How much can I go over on the amps?
While I personally don’t recommend going over 150% of the maximum amps with an Explorer power station, Jackery do not recommend going over on the amps at all.
For warranty reasons you should stick to what the manufacturer says.
Some charge controllers are more sensitive than others, but I haven’t had any problems using 200W of solar with my Explorer 500 for a couple of years.
Are Harbor Freight solar panels waterproof?
The junction box on the back of the panel is water-resistant, and the SAE connectors should withstand rain as long as they’re connected to another SAE connector or has the cap on.
I would ask Harbor Freight to be sure though, since it might void your warranty if it’s damaged due to rain and/or dust.
Can I combine a Harbor Freight solar panel with a panel by different manufacturer?
You can, but I don’t recommend doing so. The reason for that is that the setup is going to limited by the voltage of the lowest-rated panel.
If you have two panels that are rated similarly you won’t lose much, but be aware of the limitations.

I can’t get the harbor freight 100 W solar panels to charge the Jacari 1000. I’ve use both the 8 mm and the two prong adapter but still does not register. Not sure what else to do. Reply
Hi, Do you have a multimeter so you can test the connections? It’s likely a loose connector or a polarity problem. Reply
Can I charge a Jackery Explorer 240 with a 100 watt solar panel from HF? The one I’m looking at is the THUNDERBOLT SOLAR 100 Watt. The Jackery 240 is sold with their 60w solar panel. Is it safe to connect the HF 100 to the J240? Reply
Hi, Yes, it’s compatible and will work great with the Explorer 240. You just need the SAE to 8mm adapter (click to view on Amazon). Looks like the polarity lines up correctly, so I don’t think you need to use the included SAE reverse polarity adapter. Reply
