**What Can Different Solar Panel Watts Run**

If you have a solar panel, then you should definitely be wondering what can this solar panel power.

Luckily, in this article, we will go through some of the most -if not the most- common solar panel wattages in the market and what can they power including:

- 45 Watt solar panels
- 50 Watt solar panels
- 70 Watt solar panels
- 100 Watt solar panels
- 200 Watt solar panels
- 300 Watt solar panels

But before jumping into what appliances can a 300 watt solar panel run, first, we need to calculate how much power does a solar panel produce.

So without further ado, let’s jump right into it.

**How to Calculate your Solar Panel Power Output**

The total amount of power produced by your solar panel depends on various factors such as:

- Solar panel efficiency
- Solar Panel wattage
- How many hours of direct sunlight your panels get
- How intense is the sunbeam
- Shading
- Roof slope
- Azimuth
- And many more

For this reason, it can be pretty hard to give an accurate number, as there are many variables to consider.

However, there are a few ways to have a decent estimation of how much power does your solar panel produce.

**Method 1: The Fast Way (Less Accurate)**

To calculate the total power output of your solar panel, all you need to do is to multiply the number of direct sunlight hours you get by the solar panel wattage.

For instance, if we have a **100 watt** solar panel and on average we get **5 hours** of direct sunlight each day.

Then the total power output will be:

**Method 2: Using your Location Weather Data**

The National Renewable Energy Laboratory developed a magnificent tool that uses your location weather data to calculate the total power output of your system throughout the year.

They named this tool PVWatts and it’s one of the most accurate solar calculators in the world.

Here is how to use it:

**Step 1:** Enter your home or business address

**Step 2:** Click **Go to system info**

**Step3:** Fill in your information

**System Size:**Your solar panel wattage in kW. For example, if you wish to calculate a**200 Watt**solar panel output, then write in**0.2**in the system size square**Module Type:**This asks for your solar panel efficiency. There are 3 types to choose from:**Standard:**A crystalline solar panel with a nominal efficiency of**15%**(Polycrystalline)**Premium:**A crystalline solar panel with a nominal efficiency of**19%**(Monocrystalline)**Thin Film:**Thin-film solar cells with a nominal efficiency of**10%**

**Array Type:**There are 4 types of arrays:- Fixed
- Roof-Mount
- 1-Axis Tracking
- 1-Axis Backtracking
- 2-Axis Tracking

**System Loses:**The average system losses are**14%**, so leave it as it’s**Tilt:**This is the angle from the**horizontal of the photovoltaic**modules**Azimuth:**This is the angle clockwise from**true north**describing the direction that the array faces

**Step 4 (optional): **Fill in your kWh rate and your rate type to get an estimation of how much money will your solar panel save you each month.

**Step 5:** Click Go to **PVWatts results**

Here are the results for a **100-Watt** Roof-mounted solar panel in my location (New York):

So, on average, my **100-Watt** solar panel will produce around **0.35 kWh/Month**, which is way more accurate than the first method.

**FAQs**

**1. What Wattage Solar Panel Do I Need for Camping?**

Well, the answer really depends on your usage.

However, here is a quick calculation of how many Wattage you need per day:

- 1 LED Bulb (10 Watt) for 3 hours = 30 Watts
- Charge your mobile (5 Watt) for 2 hours = 10 Watts
- Use your laptop (60 Watt) for 2 hours = 120 Watts
- Ceiling fan (70 Watt) for 2 hours = 140 Watts
- Cooking (1200 Watt) for 20 minutes = 400 Watts

In this example, your daily Wattage usage will be around **840 Watts**.

Assuming you will get **5 hours** of direct sunlight, then a **170 Watt solar panel** will be more than enough for your camping adventure.
