Key Terms To Understand

In order to understand how much power a solar panel can produce, we first must understand some of the terminology used. We will try to explain it in the simplest terms possible for those non-electricians reading. Here are the main terms you should know:

• Kilowatt: A kilowatt (kW) is a unit of measure for electrical power and is equal to 1,000 watts. When considering how much power a solar panel can generate, this is the most important term to understand.
• Kilowatt hour (kWh): Kilowatt hours are calculated in a very simple way: measuring the amount of energy you would use if you kept a 1 kW appliance running for one hour. In this sense, it’s more a unit of measurement used as a benchmark. The kilowatt hour is the time period of the single-kilowatt appliance running for one hour.
• Direct Current Power (DC): Direct current is the type of electricity that solar panels produce. This type of energy needs to be converted into alternating current (AC) before it can be used in appliances or sent back into the grid.

Now that you understand the power lingo, you will be better equipped for random questions at pub quiz and it will be a bit easier to understand how much power a solar panel can produce.

What Is Solar Panel Output?

Rated by the amount of DC power they produce under ideal conditions, solar panels are expressed in watts (W), which gives you an idea of how much electricity you can expect your panels to generate under ideal conditions.

Most residential solar panels range from 250-400 W, and higher power ratings will provide you with more electricity. If you’re looking for an efficient way to power your home, invest in a high wattage solar panel

The Solar Equation

When many hear the word “equation”, palms immediately start sweating and they look to their neighbor to copy off of. But bear with me here, the solar equation isn’t as difficult as it may sound.

Amount of Available Sunlight

To calculate the amount of power that a solar panel can produce, you will need to know the amount of available sunlight, the size of the solar panel, as well as the efficiency of the panel itself.

Solar Panel Area

The equation is fairly straightforward. Start by determining the area of your solar panel in square meters. To do this, all you need to do is multiply the length of your panel by the width of the panel.

Next, determine the amount of sunlight that the panel is exposed to. This is measured in kilowatt-hours per square meter (kWh/m2) and is affected by the time of day, season, and location. For my American readers, a meter is pretty much a yard. I meter is 1.09 yards.

Solar Panel Efficiency

Finally, you will need to know the efficiency of your solar panel. This is the ratio of the amount of energy it will produce compared to the amount of energy it absorbs. The efficiency of modern solar panels used in residential installs is typically about 20%, but varies depending on the type of solar panel (We’ll get into this in a bit).

This efficiency will be reduced if your solar panels are dirty, so make sure to clean your solar panels regulary. It is also important to repair solar panels as soon as any issues are found.

Once you have all this information, you can calculate the amount of energy your solar panel will produce with this equation: Energy (kWh/m2) = Solar Panel Area x Available Sunlight x Efficiency

For example, let’s say you have a solar panel that is 4m x 2m, receives 4 kWh/m2 of sunlight per day, and has an efficiency of 20%. The equation looks like this: Energy (kWh/m2) = 4m x 2m x 4 kWh/m2 x 20% Energy (kWh/m2) = 32 kWh/m2

That means your solar panel will produce 32 kWh/m2 of energy per day! With this equation, you can easily calculate how much power your solar panel will produce and make the most of the sun’s energy.

Type of Solar Panel and How They Affect How Much Power Is Produced

If you’re looking to maximize the amount of power your solar panel produces, you’ll want to focus on the types of solar panels that offer the highest efficiency ratings. Here’s a breakdown of some of the most popular types of solar panels and how much power they can generate:

• Monocrystalline Solar Cells: Monocrystalline Solar Cells are the most efficient type of solar cells, with efficiency rates ranging from 17-22%. They’re also the most costly and require the most space when installed.
• Polycrystalline Solar Cells: Polycrystalline Solar Cells are slightly less efficient than Monocrystalline Solar Cells but are cheaper and require less space when installed. Efficiency rates for Polycrystalline Solar Cells are around 13-16%.
• Thin Film Solar Cells: Thin Film Solar Cells are the least efficient type of solar cells, coming in at around 11-14%. Thin film solar cells are also the cheapest, and require the least amount of space when installed.

There are some new solar technologies in the works, that may someday give us much higher efficiency and end our addiction to fossil fuels that is destroying our planet. For now, the type of solar panel you choose will come down to your power needs and budget.

The fact that you are looking to use solar panels to produce power for your home is the most important thing.

How Many Solar Panels To Power An Entire Home

Inquiring minds want to know, how many solar panels are needed to power an entire house? This is an important question to consider when deciding whether or not to make the switch to solar energy.

The answer to this question isn’t a simple cookie cutter answer. It depends on the size of your home and the amount of energy you use. The answer to this question usually requires a solar professional to come to your house and do an assessment. But there are some calculations you can do to get a better idea.

First, let’s look at the average solar panel size. In 2022, the average solar panel size is 5.4 feet by 3.25 feet. This size of panel usually produce between 250-400 watts of power.

Now, let’s take a look at the average energy use of a typical US home. According to the US Energy Information Administration, the average home in the US uses 886 kilowatt hours (kWh) of energy per month.

We are going to use some rough estimates to answer the question of how many solar panels to power an entire home. Keep in mind, these numbers will vary quite a bit based on the efficiency and size of your solar panels, the amount of sun you get, and how much power your home uses.

In a very rough estimate, an average solar panel produces 1.4 kwh per day. That means that it produces 42.58 kwh per month (1.4 per day X 30.42 days in a month=42.58). Since the average house uses 886 kwh per month, we can divide 886 by 42.58, to get 20.8.

So given these very rough estimates, a house will need 20-21 solar panels per month to power it completely.

How To Store The Power Your Solar Panels Produce

Whether you are on the grid or off the grid, you can still benefit from storing the energy your solar panels produce. How can you store the energy your solar panels produce? Unless you have Ryu or Ken as neighbors, capturing your excess solar power in hadoken’s (street fighter fans know what I’m talking about, others please disregard). There are two main options: battery storage and grid-tied storage.

Battery storage involves using special batteries (unfortunately, the AA batteries in your TV remote won’t do the trick) to store the energy generated by your solar panels. These batteries are designed to store large amounts of energy for long periods of time, and they can be recharged when needed.

The main drawback to battery storage is they are quite expensive and require regular maintenance. If you want to learn more, check out our comprehensive guide on solar panel batteries.

Grid-tied storage involves sending the energy your solar panels generate to the power grid, where it can be used by other customers. This is usually the most cost-effective option, as it eliminates the need for expensive battery storage.

Selling excess power generation back to the grid is called net metering. The policies surrounding net metering vary by location, so check your local regulations. You shouldn’t assume this is a viable option for you without further investigation.

Conclusion

Understanding how much power a solar panel produces depends on many factors, but using the solar equation can help you to estimate your needs. Taking into account the size of the solar panel, the type of solar panel, and the amount of sunlight can help you to make the best decisions in regards to your solar system.

We wish we could give you a more straight forward answer, but some issues are a bit more complex. We suggest contacting a local solar professional to come to your home to assess your specific situation and get you a specific estimate.
