200W Solar Panel Output Per Day

By SSK Admin December 18, 2021

200W Solar Panel Output Per Day

If you are looking at buying 200-watt solar panels, then you might want to know what the 200W solar panel output per day is.

A 200-watt solar panel produces less electricity than most residential panel models, but it is the perfect choice for camping, a small cabin, or an RV. This means, though, that you need to be aware of how much power you will be using with a 200-watt solar panel.

So if you’re looking for the answer to how much power a 200-watt solar panel produces, then you’ve come to the right place. In this article, we will explain exactly what a 200W solar panel’s electricity output per day is.

What Is A 200W Solar Panel’s Electricity Output Per Day?

200W Solar Panel Output Per Day

A 200-watt solar panel’s power output varies throughout the day.

First of all, wattage indicates the amount of electricity that is being generated by your solar panels. A 200-watt solar panel will produce an output of 200 watts under ideal conditions, such as a summer afternoon under a clear, blue sky. A­­­ 200W solar panel produces its highest power output between 11 AM and 3 PM.

On average, a 200-watt solar panel should be able to produce an average 600Wh of solar energy per day. This is far below the amount of energy required for most family households. It can still be beneficial if you want to reduce electricity costs, run small appliances, or own a tiny home.

If you are unsure, educate yourself about what you can run off 200-watt solar panels.

In essence, a 200-watt solar panel should produce 200W of solar power. However, the power output that is obtained from your panels can differ, depending on numerous factors.

To figure out what your solar panel’s power output is, it is recommended that you use a formula. To understand the formula, you need to get to good grips with the term, efficiency, in solar energy.

Solar Power Efficiency

Efficiency informs you how much sunlight is being converted into electricity by your panels. For instance, if the solar panel’s efficiency is at 20%, then the panels can transform 20% of the sunlight that passes through the panel's structure. 

What Affects Solar Power Efficiency?

Efficiency is affected by numerous factors, which include the surface that surrounds the panel’s rooftop. The surface can be impacted by elements such as shading or covering from trees or buildings, dust, dirt and pollution, thick cloud coverage, and snow.

This section will discuss some factors in more detail.

Location And Direction

In addition, location, and direction can also affect the solar output.

Some locations receive more sunlight than others. The more the 200W solar panels are exposed to sunlight, their energy production increases. With that being said, if you live in an area with minimal sunlight, you can still benefit from solar power.

Your solar panels’ direction can also have a big impact on the energy output. You want to place your panel in a direction that receives maximum sunlight, so it is best to orient the solar installation either to the west or south. Solar panels can still produce a good amount of power if it faces the east.

The angle and tit of the solar panel are also important. You would want to install your solar panel at an angle of 35 degrees to ensure that it works at its best. If that is not possible, make sure to angle your roof between 10 or 60 degrees.

This is not an issue if you are using solar panels for an RV that gets on-the-go power from the sun. If you have an RV, find out whether 200-watt solar is enough for an RV

Time Of The Year

Bear in mind the time of year. Solar panels produce the most power in the summer months because the days are longer and there are more hours of sunshine. However, if it gets extremely hot, the solar panels can overheat. If the panels overheat, there is a reduction in the amount of power they can generate.

Cleanliness Of The Solar Panels

If your solar panel is covered in rubble, then power output will be reduced. The power output falls because the debris stops the sunlight from hitting the panel. Unfortunately, you cannot count on any rain to wash off the debris. For this reason, you need to implement a cleaning routine. Make sure that you clean the solar panels with soap and a damp cloth.

Solar Energy Output Formula

To calculate your solar panel’s output, you can use the following simple formula:

Average hours of sunlight × solar panel watts x 75% = daily watt-hours

We refer to 75% efficiency to account for the above-mentioned variables.

As an example, we will say that you live in an area that experiences, on average, about 4 hours of sunlight. Your panel has a 200-watt rating.

The calculation is as follows:

4 hours x 200 watts x 0.75 = 600 daily watt-hours

How Many Amps Does A 200W Solar Panel Produce?

How Many Amps Does A 200W Solar Panel Produce

You may wonder, “What can a 200-watt solar panel power?”

One needs to then look at amps.

Amperage can be described as the number of amps that are consumed by something per hour.

Amps are like gallons of fuel. Just like we consume gallons of a gas tank when we drive a car, we consume amp hours of the battery when we run any appliance. You would use a converter charge to put the amp hours into the battery, just like you would fill a gas tank at a gas station.

In this case, you have the power of solar. Any time the sun is out, the amp hours will be returned to your battery.  

It is important to understand that when it comes to solar panels and batteries, we are not referring to the amount of power they consume. Instead, we refer to the amount of power that solar panels can provide.

For example, if a solar panel claims that it produces 10-amps, then it will roughly provide 10-amps of power for each hour that is exposed to sunlight.

Working with the fact that most areas receive 6 hours of sunlight per day, a 200-watt solar panel can produce around 10 to 12 amps of power per hour. This should be about 60 to 70 amps of power per day.

You can also read whether a 200-watt solar panel can run a refrigerator.

What Will Affect The Number Of Amps A 200W Solar Panel Can Produce?

The average amps for a 200-watt solar panel should be around 10 to 12 amps per hour, but this will not be consistent.

The amount of sunlight can have an impact on the amperage amount. A solar panel will hit a maximum number of amps produced per hour if it is a bright, sunny day. If the day is cloudy and then the solar panel ends up in a shady area, then it will be exposed to minimum sunlight. You can then expect the number of amps to fall.

Solar Power Concepts

After delving deep into the topic of 200-watt solar panel output, we thought it best to explain some concepts just in case.

Firstly, a solar panel's output is exhibited in watts. So, the higher the solar panel’s wattage, the higher amounts of electricity can be produced.

Secondly, while your appliances are being powered by the solar panel, energy is being consumed in Watt-hours (Wh).

Final Thoughts

200W solar panels may not be the most powerful model out there, but it is versatile and compact. It is perfect for anyone who wants to run small appliances as well as reduce electricity costs.

It is best to be conscious of the external factors that may affect the solar panel power output and then figure out if the 200-watt solar panels are worth the purchase.

FAQs (200W Solar Panel Output Per Day)

Can Solar Panels Produce Power When The Sun Is Not Shining?

Yes, albeit a bit less than when the sun is shining. No energy will be produced at night when the sun is not in the sky. For this reason, you can still benefit from a solar panel, even if you live in a cloudy city.

What If Snow Gets Onto My Solar Panels?

If snow is covering your solar panels, then it can impede the solar panel’s ability to convert sunshine into power. Fortunately, snow cannot cause any structural issues to your panels. If a lot of snow does begin collecting, then you can just clean the panels.

Will I Receive An Electricity Bill With Solar Panels?

Unless you have battery storage and/or you are completely off the grid, then yes, you will still receive an electric bill. If you are planning on getting a battery for your 200-watt solar panels, take a read: How long does it take a 200W solar panel to charge a 12v battery.
