Types of Solar Panels

People are investing in alternative methods of electricity in hopes of converting to green living; they are opting for solar panels. Therefore, it is important to know how many KW an average solar panel produces per day, what types of solar panels are available, and the factors that affect the power output, before you decide to go all in. Investing in a solar panel system requires you to know about the materials, power, life, and cost of a solar panel system. Additionally, finding one that fits the demands of your residence will also benefit you and your home in the future.

There are two main types of solar panels: 

  • Monocrystalline Solar Panels
  • Polycrystalline Solar Panels

The monocrystalline solar panels are known to be more efficient because they can perform in very hot temperatures as well as in cloudy weather. It gives a greater power output and is therefore comparatively more expensive than other systems.

The polycrystalline solar panels, on the other hand, have lower efficiency and give out lower power output. They are cheaper than monocrystalline panels and don't work well in high temperatures

What are the Major Factors that Will Affect the Electricity Being Produced by a Solar Panel?


To determine how many KWs an average solar panel produces in a day we have to look at a lot of factors that affect the output of a solar panel. When it comes to what these factors are and how they can affect electrical output, there are a few things to keep in mind. 


  1. Size of the Solar Panel
    The most important factor to determine the electrical output of a solar panel is its size. The bigger the size of the panel is; the more surface area it uses to harvest the sunlight. The rays of sunlight are then absorbed and converted into electrical energy by the solar panel. A solar panel twice the size of another will be able to absorb double the amount of solar energy and hence will produce twice as much electricity.
  2. The Material used in the construction of the Solar Panel
    There are a lot of materials, some more effective than others that can be used in the construction of a solar panel. One of the best materials to construct a solar panel with is a monocrystalline panel. They are expensive but have a greater electrical output. 

    Alternatively, polycrystalline panels are also used for solar panels which cost less but produce more waste and are less effective than monocrystalline panels. 
  3. Amount of Sunshine in your Area
    One of the important factors that determine the power output of a solar panel is the amount of sunshine it receives. Solar panels harvest the sun’s light and convert it into electrical energy so the electrical output is directly proportional to the sunlight your residence receives. Placing the panels in direct sunlight is very important to generate a good power outflow. 
  4. Placement of the Solar Panel
    You can harvest maximum sunlight if you place your solar panels facing the South or South-West side. The South receives the highest intensity of the sun and does so for longer periods. South-facing roofs get the best results although the panels work on roofs facing east or west as well. 
  5. The angle of the Solar Panel
    A roof should be tilted at an angle of 30 degrees to achieve the best results from the solar panels installed on it. If not, the panels can be erected with supports to achieve the 30-degree angle for the best performance. 
  6. Overhang or Shade
    Solar panels need direct access to the sun to harvest solar energy. Therefore, it only makes sense for the panels to be placed away from shade or any overhang to ensure maximum solar absorption. Any shade or blockade will make the panels less efficient. 

How Much Energy Does a Solar Panel Produce Per Square Foot?


There are a lot of factors to consider before you can effectively determine how many KWs a solar panel produces in a day or a month. Figuring out the energy produced by each square foot of solar panels is crucial when it comes to the area you want to dedicate to these panels on your roof.


If you have a panel that produces 265 Watts of energy and is 65.4 by 39 inches in size, the energy produced by a solar panel per square foot will be 15 Watts.

How Much KWs Does an Average Solar Panel Produce Per Day?


The answer to the question of how many KWs can an average solar panel produce per day is not straightforward because there are different types of solar panels available in the market. They range in size, materials, absorbing different values of solar power, and having various levels of Wattage.


If you have a solar panel that has an output of 250 Watts, you can multiply those Watts by the amount of usable sunlight your roof gets in a day to calculate its total power output. For instance, in the USA, the average amount of peak sunlight per day is generally four to five hours.


To determine the amount of KWs an average solar panel produces per day, simply multiply the Watts, (250W) by the sunlight hours (4) which will give you the energy output of the day (1000 Watts). 

How much kWs Does an Average Solar Panel Produce Per Day?


If you have determined how much energy an average solar panel may produce in a day, it is easy for you to calculate the energy it produces in a month. Multiply the total Watts of energy produced by a solar panel in a day by the number of days in that month, depending on which time it is. An average solar panel of 250 Watts can be expected to generate around 30,000 Watts or 30 kilowatts in a month.

How Much Power Do My Electrical Appliances Need?


Some appliances are energy efficient and require less electrical input to perform their functions while some appliances require a lot of energy. The need for solar panels can be effectively calculated by determining the individual requirement of each electrical appliance before you install your solar panels.


There is a high chance that you might not be able to power your entire house with solar panels, especially if you have less roof space. However, in such cases, installing a stand-by portable solar generator is your best choice. 

How Many Solar Panels Does an Average House Need?


It's hard to figure out how many solar panels an average home needs without having a complete idea of the number of people living in the home and the number of appliances being used. But on average, a normal household needs around 37 kWh per day. 


If you have solar panels that produce 1 kWh of energy per day, you will need around 37 solar panels to power your home. Still, it is not as simple as multiple factors are affecting the output of energy in a solar panel, so the best is only a rough estimate. If you have all the ideal conditions for a solar panel to work at full efficiency, then these calculations might apply. 

How to Measure the Efficiency of a Solar Panel?


Not all of the sunlight that hits the panels is absorbed and converted into usable electrical energy. Solar panels previously had an efficiency rate of about 6% - 10% but with newer modifications and better technology, the efficiency has risen to 30%.


To calculate the efficiency of your solar panel, you have to keep in mind that various factors are at play. Therefore, you must always leave room for error while calculating.


Here are some steps you need to follow to determine the efficiency of a solar panel:

  • Determine the surface area of the solar panel.
  • Find out the power rating of the solar panel in Watts.
  • Divide the number of Watts (power rating of the panel) by the surface area of the panel and multiple by 100. For example, (250 Watts/ 1500 sq. m. x100). 


With the help of this equation, we have determined that a solar panel with a power rating of 250 Watts will have an efficiency of 16.67%.

Frequently Asked Questions about How Many KWs does a Solar Panel Produce in Florida


How Many kWh Should My Solar Produce in a Day?

On a bright sunny day, your solar panel receives five hours of direct sunlight. Multiply the hours of the sunlight (5) with the Wattage of the solar panel (290) which will tell you the Watts of energy produced by the solar panel (1450 Watts). 


This means that on a good day your solar panel should produce about 1.5 kilowatt-hours. 

How Many Solar Panels Do I Need for 1000 KWh Per Month?

If your panels have a power output of 250 Watts and you receive four good hours of peak sunlight per day, you require forty solar panels in total to reliably generate 1000 kilowatt-hours of energy per month.


How Much Power Does a 10KW Solar System Produce Per Day?

A 10KW solar unit will generate about 40kWh per day. The outcome can differ according to certain environmental factors, your location, and a variety of other factors. 


What Can You Power with a Single Solar Panel?

If your solar panel is producing 1.5 kilowatt-hours per day, it ends up being around 45 kWh per month. That is enough energy for you to power several small appliances. But if you want to power bigger appliances like an AC or a refrigerator, you will need more solar panels.
