What is a 200W Solar Panel?

When possible, it’s useful to utilize solar panels as a primary or backup option for energy in the instance of outages and to generate your own clean energy. 

The sun shines directly or indirectly on the solar panel, and that energy from the sun gets absorbed into the photovoltaic cells on the panel. Thus, electricity flows thanks to the electrical charges that start moving because of this absorbed energy. 

Usually, 200-watt solar panel kits consist of two 100-watt panels sold together that equal 200 W total. This arrangement means that the lot will produce slightly less electricity than other residential solar panel models. 

How much power you generate depends on the season and how much sunlight you can get, your geographic location, the size of your panels, shading, how clean your panels are, and the type of solar panels you purchase. 

Benefits of a Solar Panel

One of the primary benefits of 200W solar panels is the ability to reduce energy bills. The average amount of power that the panel can produce is much less than the amount of energy a standard household consumes.

However, it is still possible to power your small electronics or a tiny home if you have multiple batteries and you manage the times that you run the devices. Still, this saves you money on your energy bills by using solar panels. 

What Can I Run With a 200-Watt Solar Panel?

You can run the following types of devices with a 200-watt solar panel 24 volt:

  • A 45W laptop for 22 hours
  • A 625W microwave oven for an hour and a half
  • A 1000W coffee maker for one hour
  • A 60W light bulb for one hour

Some of these appliances seem too high to function on just 200 watts. In reality, using a battery bank and strong energy can allow you to power heavy-duty appliances worth the hell of the 200W solar panel. 

You’ll also need a power inverter to convert the 12V DC power into AC power. We’ll get into that later, but keep this possibility in mind. You don’t need to use batteries for your solar panels, but you should.

As long as you’re aware of the amount of energy you’re producing and the amount you need to offset, managing your panels and stored energy won’t be too challenging.

Remember that energy consumption is measured in watt-hours, and you calculate that by multiplying the watts (power input) by the hours (time of usage).

Therefore, to know what your 200W solar panel can run, you’ll have to inform yourself of how much energy your devices consume. 

Solar Panel 12V vs. Solar Panel 24V

When you use a 12-volt solar panel system, it’s best for use with boats, an RV, cars, etc. They are beneficial for smaller needs but the 24-volt system can help you power a family home. While it’ll cost you more upfront, you’ll also have a great return on your investment.

You can use the 24 V for appliances that require 12 and 24 volts, which makes it more efficient concerning heat loss. Overall, it is a better choice because of its compatibility and versatility.

How Many Batteries Do I Need for a 200-watt Solar Panel?

If you want a power supply that goes uninterrupted even on days when the weather isn’t the best (clouds, rain, snow, etc.), you’ll need batteries. They serve as a storage unit to endure that you have a constant energy supply. 

If you didn’t use batteries with your solar panels, you wouldn’t have emergency backup power. Batteries are also useful for storing an oversupply of energy that your panels absorb. 

You can charge the battery to power microwave ovens, laptops, coffee makers, drills, toaster ovens, and other standard appliances. 

What Are the Best Kind of Solar Panel Batteries?

It’s best to use lithium batteries, which are the top recommendation by solar panel manufacturers. They usually come with extended warranties and a long lifespan, excellent power output, and are more reliable than other battery types. 

The best match for a 200 W solar panel is typically a 500Wh 12V battery. It’s best to get two of them to ensure that you have enough. 

Remember that how many batteries you connect to your solar panel inverter will depend on how long you want to run your appliances.

What Size Solar Controller Do I Need for a 200w Solar Panel?

A charge controller is a device that prevents the batteries from absorbing too much charge. Therefore, it helps to extend the lifespan of your batteries. 

You’ll have to know how much current the solar panel produces to decide on the size of the charge controller. 

Usually, that’s between 8-12 amperes if your solar panels get a good amount of sunshine each day. If we assume that they do, you should get a charge controller that’s at least 15 amperes (amps). 

What Can a 200W Inverter Run?

A 200-watt power inverter is a portable low-powered device that can provide grid power to smaller appliances while out and about in an RV or car or in an emergency. 

You can easily damage them if you overload them, as they have limited capabilities. They do, however, have built-in overload protection. The continual power draw doesn’t go beyond 200 watts, and the surge power draw isn’t over 400 watts. 

Ensure that you review the manufacturer’s manual for your specific make and model to know the limitations of your device. 

Here’s a list of some of the appliances that can function with a 200W inverter:

  • GPS
  • Multiple 32-inch TVs
  • Laptop
  • Tablets
  • Mini-fridge
  • Christmas lights
  • Cell phones

Here are some appliances that are most likely not to work in tandem with the 200-watt inverter’s high power draw:

  • Vacuum cleaners
  • Small room coffee pots 
  • Electric heaters
  • Kettles
  • Tire compressors

Appliances like or similar to kind above all have a maximum power draw higher than 200 watts, and as a result, they’ll cause the inverter to overload and force it to shut down.

How Fast Will a 200 Watt Solar Panel Charge a Battery?

A 12V battery connected to a 200 W panel that produces one amp will reach a full charge within five to eight hours. There are other factors to include that can make the estimation more difficult.

Factors that affect charging time include battery condition, the quality of your panel, the efficiency of the charge controller, and the amount of sunlight absorbed. How well these components function will dictate the charge efficiency.

On the other hand, if we presume that the battery amp you have has an hour rating that corresponds to the amps generated by the panels, the estimated time to fully charge is about five to eight hours.

Additional Factors That Affect Charging

Furthermore, the solar panel must face the sun without being obstructed. Keep in mind that solar panel charging will take longer on days when there’s an overcast and vice versa; on days where there’s full sun, charging is faster.

Here are four factors that dictate how long it will take for your battery to charge:

  • The remaining battery life 
  • Sunshine availability
  • Batteries with varying amounts of amps
  • Solar cell power output

Amount of Amperage 

Among these factors, the amount of amperage is a crucial factor. This figure describes the energy output that the battery is capable of holding. When a battery has higher amperage, there’s more power, and therefore it takes longer to charge such a battery.

For the most part, a 75 AH battery only takes about 50 percent of the time it hasn’t a 200 AH battery to charge.

When the average amount of sunshine is factored in over the course of a day, the solar panel will run at a maximum capacity of approximately the five-hour level, no matter the season.

Deep Cycle Batteries

If you have battery-backed or off-grid solar panels, you should use deep cycle batteries as a battery backup. These types of batteries closely resemble car batteries; however, these batteries deliver power for a longer period, and they are rechargeable.

It is possible to use up to 80 percent of the total amount of your deep cycle battery’s capacity without causing any harm. When using a battery with a capacity of 100 amp-hour, only use 80 amp-hours. 

To extend the lifespan, manufacturers advise consumers not to allow it to drop below 45 percent. These properties are what make deep batteries great for solar panels.
