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 Much Energy Does a 100 Watt Solar Panel Produce?
Just so you know, this page contains affiliate links. If you make a purchase after clicking on one, at no extra cost to you I may earn a small commission.
I recently tested a 100 watt solar panel for 10 days to shed insight on how much energy solar panels can produce.
My 100 watt solar panel output an average of 431 watt hours per day. The total energy produced over the course of my test was 4.31 kilowatt hours (or 4,310 watt hours).
Based on my test, I’d say that, on average, a 100 watt solar panel will output around 300-500 watt hours per day.
But solar panel output varies considerably based on factors like location, shading, weather conditions, and time of year. For instance, over the course of just 10 days of testing, my panel had days where it produced as low as 50 watt hours and upwards of 600 watt hours.
Keep reading for my full test results, as well as snapshots of the solar panel’s power output at various points during the test.
Video
I made a video of my power output test to accompany this article. Check it out below and consider subscribing to my YouTube channel if you like DIY solar videos like this!
I mounted the panel at the optimal tilt and azimuth angle for my location (Georgia) and time of year (April), and placed it in a sunny spot in my backyard.
With my setup complete, I connected the solar panel at midnight on Day 1 to make sure that, come sunrise, the solar panel was in position to collect every possible watt hour of energy.
With that, the test was underway!
Weather
- Conditions: Sunny all day
- Highest temperature: 81°F (27°C)
- Lowest temperature: 39°F (4°C)
Power Output
At 1pm on Day 1, I recorded the solar panel outputting 94 watts. That’s actually great output from a 100 watt solar panel. Solar panels only output their rated power in ideal conditions, so seeing anything close to 100 watts from a 100 watt solar panel is great.
At 3:30pm, the panel was outputting 82 watts.
By 5pm, branches from a nearby tree had started shading the panel and it’s output had dropped to 13 watts.
At 7pm, the sun had almost set and the panel was heavily shaded. It was outputting just 2 watts.
Results
- Total energy produced: 590 watt hours
- Max output: 95 watts
Weather
- Conditions: Sunny all day
- Highest temperature: 82°F (28°C)
- Lowest temperature: 46°F (8°C)
Power Output
At 10am, the solar panel was outputting 49 watts. Though it was in direct sunlight, it was generating medium output due to the low angle of the sun.
At 1:30pm, the panel was outputting 90 watts.
At 4pm, the panel was still outputting a respectable 76 watts.
By 7pm, the output had again dropped to just a few watts.
Results
- Total energy produced: 560 watt hours
- Max output: 95 watts
Day 5
Note: Days 3 and 4 were similar to Days 1 and 2, so I’m skipping ahead here. From now on, I’ll just include snapshots from days with different weather conditions.
Weather
- Conditions: Cloudy in the early morning, mostly sunny for the rest of the day
- Highest temperature: 81°F (27°C)
- Lowest temperature: 57°F (14°C)
Power Output
It was a little cloudy at 10:30am, so the panel was only outputting 20 watts.
At 1pm, I recorded the panel outputting a whopping 103 watts! That was the highest output I captured on camera for the entire test.
How can a 100 watt solar panel produce more than 100 watts?
Well, the conditions have to be just right. The panel can’t be too hot, because solar panels output less power as they heat up. And, of course, it has to be very sunny. What’s interesting is that this is what the sky looked like at the time I recorded the output of 103 watts:
It looks to me like the sun is reflecting a bit off the nearby clouds. This is actually a common phenomenon called the Cloud-edge effect that can produce spikes in solar panel output. Pretty cool!
At 4pm, the panel was outputting 80 watts.
At 5pm, the panel was partially shaded and outputting 16 watts.
Results
- Total energy produced: 470 watt hours
- Max output: 105 watts
Weather
- Conditions: Cloudy all day
- Highest temperature: 61°F (16°C)
- Lowest temperature: 55°F (13°C)
Power Output
Day 9 was completely overcast all day, so the panel’s output was greatly reduced. At 9:30am, it was outputting 7 watts.
At 12pm, the panel was outputting 21 watts. That’s more or less typical for a 100 watt solar panel on a very cloudy day.
At 2:30pm, the panel was outputting 7 watts.
At 6:30pm, the panel was outputting 3 watts.
Results
- Total energy produced: 90 watt hours
- Max output: 39 watts
Weather
- Conditions: Cloudy and rainy all day
- Highest temperature: 63°F (17°C)
- Lowest temperature: 55°F (13°C)
Power Output
Day 10, the final day of my test, had terrible weather. It was dreary and overcast the entire day. And it rained on and off for half the day.
At 9:30am, I recorded an output of 2 watts.
At 12pm, the panel was outputting just 7 watts.
At around 1pm, the rain started. I checked the panel’s output at 1:30pm: 4 watts. Keep in mind, it was around that time just 5 days ago when I measured an output of 103 watts.
It was still raining at 3pm. At that point, the panel was outputting 7 watts.
And, for the last power output check of the entire test, I checked the panel’s output at 6pm. I measured 4 watts.
At 11:59pm on Day 10, I disconnected the panel, thereby ending the test.
Results
- Total energy produced: 50 watt hours
- Max output: 29 watts
Test Results
Here are the final numbers from my test:
- Total energy produced: 4.31 kWh (4,310 Wh)
- Average daily energy production: 431 Wh
- Highest daily energy production: 590 Wh
- Lowest daily energy production: 50 Wh
- Highest solar panel output: 122 W (I wish I had caught this on camera…that’s crazy!)
So let’s circle back to the question I posed in the title of this post: how much energy does a 100 watt solar panel produce?
Based on this test, this is how I’ll answer the question: a 100 watt panel will produce, on average, around 300-500 watt hours per day.
And to that already wide range I’ll add a big stinking asterisk, because the actual value can vary widely based on a variety of factors like weather, shading, location, and time of year.
As we saw during my test, on a perfectly sunny day my 100 watt panel produced upwards of 600 watt hours. And on a day where it was cloudy and rainy all day, it produced as low as 50 watt hours.
Factors Affecting How Much Energy Solar Panels Produce
I ran this test to get a general idea of how much energy a 100 watt solar panel produces on an average day. But how much energy your solar panel produces will depend on a number of factors, such as:
- Solar panel wattage: Obviously, the bigger your solar panel, the more energy it will produce. The data from my test applies to 100 watt solar panels.
- Shading: Solar panel output drops when even a small part of the panel is shaded. The more time your panel spends partially or fully shaded, the less power it will output.
- Weather and temperature: How cloudy or sunny it is will have a big effect on solar panel output. Also, solar panel output drops as temperature increases.
- Sunlight intensity: How much energy the sun outputs over a day — often referred to as “solar irradiance” or “solar insolation” — naturally fluctuates over the course of a year. You can use our solar irradiance calculator to find out how much sunlight your location gets. Sometimes you’ll hear a location’s daily amount of sunlight referred to as “peak sun hours”, which is a similar unit of measurement as solar irradiance. We also have a peak sunlight hours calculator you can use if you prefer those units.
- Tilt and azimuth angle: There is an optimal angle to mount solar panels at depending on location and time of year. The direction you face your panel, known as the azimuth angle, varies by location and also affects output.
- Soiling: The dirtier a solar panel is, the less power it will output. To maximize your panel’s output, it’s helpful to clean the panel regularly.
- Location: Some locations and latitudes naturally receive more sunlight than others. Florida is sunnier than Alaska, for instance.
- Type of solar panel: Monocrystalline and polycrystalline solar panels respond differently to temperature and weather conditions.
- Charge controller or inverter efficiency: In DIY solar systems, the type (PWM or MPPT) and efficiency of your charge controller play a big role in how much of the solar panel’s power output gets sent to the battery. In residential solar systems, the efficiency of your system’s microinverters affects the overall output.
- Wiring configuration: If you’re using multiple solar panels, how you wire them together affects their power output and how they respond to shading.
- Battery state of charge: In off-grid solar systems, the energy your solar panel produces gets stored in a battery. Charge controllers monitor the battery voltage to estimate the battery’s state of charge, and, depending on that (plus the battery type you’re using), they will increase or decrease the solar panel’s output. For instance, when a battery is mostly charged, the charge controller will usually enter an absorption stage where it doesn’t use all of the available power output by the solar panel. The more time your battery spends mostly or fully charged, the more your charge controller will throttle the solar panel’s output.
- Solar panel age: Solar panel output drops over time, so if your panel isn’t outputting as much as you’d like, it may be due to reductions in power output due to aging.
Ways to Increase Solar Panel Output
Now that we know the main factors affecting solar panel output, we can cover some of the main ways to increase it.
- Move the solar panel to a sunnier spot: Shading greatly reduces solar panel output, so, before mounting your solar panel, pay close attention to which of your available mounting locations gets the most direct sunlight over the course of the day. If possible, move the solar panel.
- Reduce shading: If you can’t move your solar panel, consider trimming branches or moving objects that cast shade on the panel.
- Optimize tilt and azimuth angle: Use our free solar panel angle calculator and solar azimuth angle calculator to find the optimal angle and direction to mount your panel.
- Clean the solar panel: Over time, dirt, pollen, bird droppings, and other debris may collect on your solar panel. Solar installer Palmetto recommends using warm water, dish soap, and a soft cloth or sponge to clean the panel glass every so often.
- Add more panels: If a single solar panel isn’t cutting producing enough energy, you can buy another and wire the panels in series or parallel to increase power output.
- Upgrade your charge controller: If you’re using a PWM charge controller, consider switching to an MPPT charge controller. Depending on your location, this may have a smaller or larger effect on energy production.
- Upgrade your panels: If you have older or low-efficiency solar panels, swap them for newer or higher-efficiency panels.
Of course, as a last resort, you can always just buy a bigger solar panel.
Tip: If you try the above and your solar panel is still producing significantly less energy than you expect, your panel may be damaged. At that point, I’d recommend testing your solar panel.
The Bottom Line
After 10 days of testing, I learned that, on average, a 100 watt solar panel will output around 300-500 watt hours per day. However, solar panel output can vary widely based on factors like shading, weather, location, and time of year.
For instance, the lowest output I measured in a day was 50 watt hours, while the highest I measured in a day was 590 watt hours.
If you want to increase your solar panel’s power output, the easiest ways to do this are by moving the solar panel to a sunnier location, reducing shading by trimming branches or moving objects that cast shade on the panel, optimizing the panel’s tilt and azimuth angle, and cleaning the solar panel when it gets dirty.
If those methods fail, you can increase output by buying another panel and wiring them in series or parallel. And, as a last resort, you can always buy a bigger solar panel.

Let customers speak for us
I was a backer of this product and have been using it for almost 3 weeks now. My initial reason for backing this product is the versatility it offers and unique design. This is not a copycat same old same old power station!
The battery packs can be used as their own power station (w/the DIY moduals) or inserted into the host to power/charge it with 1 or 2 battery packs. Usually mixing batteries with different states of charge or age is an issue, but not with this product. It really does feel like they thought of everything with this design.
Charging is a snap with daul inputs up to 200w. A 100w USB C power supply is a good option to purchase if you don’t have one. All methods of charging I have tried worked well. I have thrown about all I can at this thing and it hasn’t skipped a beat. Charging can be from your cars power port, wall power supply, USB C and solar. I even used a 3rd battery to charge or supplement capacity using USB C.
It has pass-through charging, but it’s not recommended while dual charging. Hot swapping the batteries is easy. Just make sure it’s one at a time and in the right orientation.
The SERI 100w solar panels are really nice, but a bit on the heavy side and really long. The panels have plenty of loops and grommets for mounting them. I usually use a ridgeline to hang my panels staking out the bottom for the right angle to the sun. What little testing I have done they worked fine. I haven’t been able to test them or other panels in good sun yet. With the soon to be released solar to USB C adapter you will be able to charge 1 or 2 batteries at a time with solar!
So far my main testing is running my ICECO JP42 fridge that I use at home and camping. The power station displays 99 hours of run time at full charge with the frig on ECO mode set at 44°f. When the compressor kicks on it shows 46 hours of run time, but goes back up once it’s cycled. I have used the power station as a UPS for the fridge using 100w USB C to charge and the 12v port to run the fridge without issues. Other than the usual issue of the cord loosing connection when bumped.
If you’re looking for something with 600w of almost endles power and awsome options or just a great power bank to run your devices you should really look at what Runhood has to offer! So far I am impressed with my purchase and Runhood’s quick responses, even the manual is well done!
Would I buy this product again? Absolutely, already have! I will post some pictures soon after a camping trip.
Bonus! They do listen to feedback resulting in improvements and future additions. For those looking for more, I have a feeling they will keep innovating while not leaving their early adopters behind. A 4 battery 1200w 1296wh host in the works?
What Can I Run With a 100W Solar Panel?
When you think of solar power, you probably think of large panels on a rooftop. While this describes some residential and commercial systems, you may have more modest needs. A smaller, 100W panel can power several personal devices like smartphones, laptops, and some small appliances.
A 100W panel comes at a lower price point, and it’s easy to carry with you to provide off-grid electricity for a camping trip. If you’re new to solar power, a 100W photovoltaic (PV) panel is an inexpensive entry point for introducing clean, renewable energy to your life.
But is 100W sufficient for your electricity consumption needs?
How Much Energy Does a 100-Watt Solar Panel Produce?
When a solar panel has 100W of rated power, its output under optimal conditions is about 100 watts in an hour. It’s crucial to note that the full rated power of 100W is achieved in a laboratory using Standard Test Conditions of 1000W/m2 of sunlight, AM1.5, and an air temperature of 25°C (77°F.)
Such ideal conditions are rarely found in the real world. Numerous environmental factors like shade, temperature, panel angle, and Cloud cover often prevent a PV panel from generating its full rated power. Depending on these and other factors, you can expect anywhere from 25W of electricity per hour from a 100W solar panel on a cloudy day and /- 90W in bright summer conditions.
Most areas regularly receive anywhere from 3-5 hours of peak sunlight daily. When you factor in other environmental considerations, a 100W solar panel will produce 400W of electricity on average on a sunny day. 300-600 watt-hours (Wh) of energy in a single day.
What if the PV Panel Is Not Operating Under Optimal Conditions?
As noted above, the rated power of a solar panel represents the maximum wattage it can deliver. Solar panels are rated based on laboratory conditions, which rarely occur in the real world.
Several factors — some of which you can mitigate — will reduce the efficiency and the output of your panel:
- Shade. If trees or other obstructions block even a portion of the sunlight your 100W panel receives, you will generate less than the rated power. With portable solar panels, this is an easy fix. Simply move the panel into direct sunlight.
- Dirt. Dust, dirt, and debris can block your panel from absorbing sufficient sunlight. Clean your solar panels with a soft cloth, distilled water, and gentle, biodegradable soap. Never use harsh chemicals to clean PV panels.
- Heat. Somewhat counterintuitively, high temperatures actually diminish the production of solar panels. If the surface temperature of your panels exceeds 95°F (35°C), it will have a noticeable effect on output. Solar panels typically operate best in warm to mild temperatures but will still generate electricity even in extreme cold or heat. Outdoor temperatures between 59°F and 95°F degrees (15°C – 35°C) are best for solar panel efficiency. But aside from changing your location, there’s not much you can do about that.
- Angle. Correctly angling solar panels allows photovoltaic cells to receive the maximum possible amount of direct sunlight daily. For fixed rooftop installations using rigid solar panels, a 30°- 45° angle facing true south is typically best for locations in the northern hemisphere. Depending on the panel, you may be able to purchase a solar tracker to adjust the angle during the day automatically. Another advantage of portable solar panels is that you can easily adjust the angle to follow the sun’s path.
Be sure to maximize solar energy capture as much as possible during the day and store it in a portable power station or other balance of system. You’ll also need to determine your required energy consumption between charges to ensure you have enough solar panels with sufficient rated power to meet your requirements.

What Appliances Can You Run With a 100-Watt Solar Panel?
The rated power of any solar panel is only one factor in which devices and appliances it can run. Solar panels do not provide electricity directly to your devices. Instead, the solar energy captured by the panels must be converted and stored in a portable power station that supports solar charging or other balance of system.
Let’s use the RIVER 2 portable power station as an example. It offers a maximum solar charging capacity of 110W — a perfect match for any of the abovementioned panels.
Depending on the amount of available sunlight and other environmental conditions, the RIVER 2 can fully recharge from 0-100% in as little as three hours. It offers 256Wh of electricity storage and up to 600W AC power output using X-Boost.
