**How Much Power Does a Solar Panel Produce?**

As a homeowner, you want to **find** new and **creative ways** of **lowering your utility bills**. When it comes to **renewable energy,** one popular option is to install **residential solar panels.** **One residential solar panel** **generates** **250 watts per hour **on average. The** range** is **170-350 watts per hour.**

Depending on the **area **and **climate** in which you live, these panels can** significantly reduce** your** electricity bill.**

That said, there are many questions surrounding **home solar panels,** including **how they work, how much they cost**, and** how many you need **to power various devices.

Fortunately, we have compiled all this information into this handy guide. This solar panel article will show you** how to calculate** the **number of solar panels you need **and you**r total installed cost. **Then, you can compare that cost to your current electricity bills to determine your **ROI.**

Here is what you need to know.

**Solar Panel Sizes and Wattage**

When shopping for solar panels, the **two primary components** to pay attention to are** size** and** wattage.** When it comes to **solar panels for buildings**, there are **three standard sizes** available, based on the **number of cells they have**. If you're unfamiliar with how **solar power works**, each panel has a set number of photovoltaic solar cells that capture sunlight and convert it into electricity. The three options include:

**Residential Solar Panels**=**Commercial Solar Panels**=**Extra Large Panels**=

As you can imagine, **larger panels** are **not meant** for **residential properties**, so **you will need to install** **60-cell units **onto your **roof.** Most solar panels are between **1.4 inches** and **1.8 inches thick,** although **1.8 inches** is **becoming the standard **since that allows** more room** for the **cells to capture sunlight.**

Additionally, you can find a wide array of small solar panels for **RVs** and **other smaller structures.** Because there is not a US universal standard for these units, the size varies greatly. On average, these panels range from **21 to 26 inches wide**, **26 to 58 inches long**, and **0.1 to 1.5 inches thick**. The thinner models are flexible, so you can** deploy them** and **roll them back up **when not in use, *like a solar magic carpet.*

When it comes to **wattage**, the exact** output depends** on** panel efficiency. **Not all manufacturers are the same, so** some units** can be** far more energy-efficient than others**. A **single panel **can produce up to **150 watts per hour** on the low end, while a **high-end model** can deliver **up to 370 watts**. That said, **most panels generate 250 watts per hour** on average.

**How Much Are Solar Panels for a House?**

Oddly enough, when using a **solar installer** to put panels on your home, ** you will be paying per watt, not per panel.** Rather than pricing the installation as the number of 60-cell units, you will have to

**determine**your

**total power needs**.

Follow these **two steps to figure out what your costs could be:**

**Measure Your Current Power Usage.**Your utility company can give you an**average in kilowatt-hours**for the**last year**to provide you with a**reasonable estimate**of the**amount of electricity you use.**

**Figure Out How Much Sun-Facing Space You Have.**If you own a**small house**, you are**limited**in how many**square feet**you**can use.**Also, pay attention to any**roof**features that could prevent installation, such as windows, skylights, or chimneys.

If you live in a **sunny part** of the country, your solar panels will generate far** more power **than if you live in a cloudy or rainy climate. However, even if you have** fewer daily sun hours**, you could still potentially **save money **annually. The sun still delivers rays to solar panels in the winter.

**Installation costs **can vary **depending on where you are** in the **United States** as well. You can find out more **about solar costs here**.

The average cost of solar panels is **$3 to $5 per watt.** So, if you install a** 3,000-Watt system**, you could expect to pay between **$9,000 **and** $15,000 **for the whole thing.

Fortunately, there is a** federal solar tax credit **for solar installation. In

**2021**, that credit is

**22 percent.**That means that if your bill is

**$10,000,**you could receive

**$2,200 in tax credits**. Unfortunately, this credit program

**may not continue past this year**,

*so now is the time to take advantage.*

**How to Use a Solar Calculator**

When searching online for a** solar calculator**, you will notice that there are several options.

**First,**you can**calculate your annual savings**by switching to**solar power.**This**solar calculator**from Energy Sage asks for your**specific address**to determine the**average hours of sunlight your home receives**, as well as**how well**your**solar system**can**receive energy**from the sun.

**Second,**you can calculate the**energy output**from**various sizes**of**solar panel systems.**This**solar calculator**from theis a bit complex, but it can give an idea of the*National Energy Renewable Laboratory***average daily electricity**you can expect. You might need to get**specific parameters**from your solar company to**use it effectively.**

**Finally,**you can use a**solar calculator**to determine the**number of panels you need.**However, you can**do this**calculation**yourself**, as we will discuss in the next sections. All you must do is calculate the**average kWh usage**and**divide**that**by**the**average output**for each**solar panel.**

Overall, solar calculators can come in handy to **give you an idea** of **what to expect** before installing a new system. Typically, these panels **will pay for themselves** in about **10 **or** 12 years**, depending on your location, electricity rates, and your installation size.

**How Many kWh Does a House Use Per Day?**

According to the **U.S. Energy Information Association**, the **average home uses** around** 877 kWh per month.** To determine the **usage by day**, we **divide** that** by 30** to get a total of** 29.33 kWh per day.**

To get an exact total for your home, you want to** ask your utility company** for your **total kWh.** If they can't provide a monthly average, you can do the same calculation. However, some companies measure your net **metering by year**, so you will want to use that **total **and **divide by 12** to find the **average kWh per month.**

**How Many Solar Panels to Power a Home?**

As we mentioned, most panels produce around** 250 watts per hour**. When converting,** 250 watts equals 1kWh.** Depending on your climate, you could get** four **or **five hours **of **direct sunlight **on your **roof**, which would yield between** one kilowatt** and** 1.25 kilowatts** in a **single day.**

Based on our average electricity usage calculation above, **most homes** would** need to produce** almost **30 kWh daily. **Since the number of **sun hours can vary,** it is best to **be conservative with your estimates**. Even if your solar panels can deliver 1.25 or 1.5 kWh on a sunny day, you should base your forecasts on a single kilowatt-hour to be safe.

Using this data, one can say that the** average home would need at least 30 solar panels** to generate **100 percent of its energy. **That assumes you need **one kilowatt each day** (30 KW per month), and **each panel will generate one kilowatt per month**. You can do the same calculations based on your exact energy usage.

Based on the installed price of** $3-$5 per watt,** your **30-panel system **would cost **$9,000 - $15,000.**

**Solar Panel Systems FAQs**

Here are some answers about the energy output for these devices so you can understand what you can do with your new solar panels.

**How Much Power Does a 50-Watt Solar Panel Produce?**

At 50 watts per hour, this panel could produce up to**400 watts per day**, assuming a**full eight hours of direct sunlight**. On a**cloudy day**, the output may be**200 watts**or**less.**

**How Much Power Does a 1000-Watt Solar Panel Produce?**

Unfortunately, solar panels with this kind of electricity production**do not**exist for**residential properties**. However, based on**eight hours of sunlight**, a 1000-watt panel could deliver**eight kWh**of energy**per day.**

**How Much Power Does a 300-Watt Solar Panel Produce?**

As we mentioned, most panels that generate this kind of output will yield anywhere from**one kWh to 1.5 kWh per day**, depending on the amount of sunlight. If you get**eight hours of sun**, you could receive up to**2.4 kWh**from a**single 300-watt unit**.

Here are some general questions related to **solar panels** and their **electricity output.**

**How Much Power Does a Solar Panel Produce Per Hour?**

When looking at different solar panels, the**wattage rating**tells you*how much energy the unit produces in an hour.*So, a 250-watt model can create that much electricity hourly.

**How Much Power Does a Solar Panel Produce Per Day?**

To calculate this, you would take the**wattage rating**of the panel and**multiply it by**the**total hours of direct sunlight**it gets.*So, if you have a 300-watt panel and get an average of five sun hours per day, its energy output would be 1.5 kWh.*

**Can a 100-Watt Solar Panel Run a Refrigerator?**

The short answer is**no**because your**fridge stays running 24/7**. Not only that, but most refrigerators**use more than 100 watts per hour**, with many models using close to 200 watts. That said, if you have a mini-fridge and only use it during the daytime, a 100-watt panel could potentially keep it running.

**What Solar Panel Wattage Size Do I Need to Run a Window Air Conditioner?**

Since **air conditioning** can be a huge** power drain during the summer**, it may be worth installing a solar system to** ****save on your cooling bills**. Our example below shows that you need **three residential solar panels** to **run** a **window air conditioner** for **8 hours a day.**

That said, there are a** few variables **to **figure out before you can determine** how many solar panels you would need to cover this one appliance's energy needs.

**BTU Power Ratings.**Although**BTU**stands for**British Thermal Unit**, air conditioners measure their cooling capacity in BTUs. The more it has, the more electricity it uses.**Here is a handy solar calculator**to determine the exact wattage of your appliance. For example, a*5,000 BTU conditioner uses 500 watts of electricity.*

**Daily Usage.**Are you running your air conditioner at all hours of the day, or just when it is hottest outside? The**total hours**you have it running will**affect your energy needs**.

**Hours of Sunlight.****How many hours**does the**sun hit**your**solar panels**on average?

For example, say that you have a **5,000 BTU air conditioner **and run it for an average of** 8 hours a day. **The AC's total energy usage would be** four kWh** (**500 x 8 = 4,000 watts/4 kW**). Additionally, let us say that you have **300-watt rooftop solar panels** that receive an average of **six sun hours per day**. At that rate, each panel would produce **1.8 kWh daily.**

So, all you do is** divide four kWh by 1.8,** which is** 2.2**. Since solar panels do not come in fractional sizes, you would need **three **of them to ensure that you can** operate** your **air conditioner without fail. **You will **need nine **if you **run your AC 24-hours a day. **Sadly, if you live in an apartment building, you most likely cannot fit three or nine solar panels anywhere outside.

**Are Solar Panels Covered by Home Insurance?**

Since installing a **new solar system **is a **significant investment**, you want to be sure that you can **protect it.** Fortunately, most **homeowners insurance policies cover solar panels** because they are **permanent installations**, much like a patio or fixed awning. Your** insurance company **may offer **solar panel insurance coverage**, but it should not be necessary.

That said, you should talk to your **insurance agent** to see whether the panels will **increase** the **repair costs** of your **home**. If so, you might want to** increase your coverage limit **to ensure that you do not have to pay out of pocket if a terrible disaster strikes. Be sure to calculate your **new insurance premium **as well so that there are no surprises.

Thankfully, since you will be fixing the panels to your **home's main structure**, there should not be any **claim sub-limits** to worry about. For example, **separate structures **like a pool house or gazebo only qualify for** up to 10 percent** of your **total coverage amount.**

Also, because they are **attached to your home**, they come with** RCV coverage**. That means if you **file a claim,** your insurer will **pay the retail price to replace the panel(s)**. Remember, though, that your **deductible applies.**
