Solar panel installation and how many are needed to power a home

When you plan to get a solar panel system for your home, you will need to find out how many panels you will require to properly power your home without issue. Of course, the procedure for solar panel installation and how many panels you will need will depend on your location, the size of your home, and the panels’ efficiency, among many other factors. More so, the price will also vary based on the factors above.

Find out everything you need about solar panel installation, how many panels are needed to power your home, and what dependencies you should know about. 

Electricity usage

Before acquiring solar panels for your property, you should ascertain your annual power usage over an entire year. How much electricity is used over a year usually depends on the appliances that the household requires, such as a refrigerator, heating and cooling units, lights, chargers, and all small appliances that may be utilized more often than not. The number often used to measure how much electricity you use is kilo-watt hours (kWh). On average, the typical American household will use 10 600 kWh, which could be a number you could use to measure how many solar panels you may require to power your home. To find out how many kWh you use per year, you can look into your utility bills from the past year and begin to calculate how many panels are needed for your property. 

Panel wattage

The solar panel wattage, or a solar panel rating, refers to the electricity output from a solar panel under prime conditions. Most solar panels use an amount ranging from 250 to 400 watts of power; such numbers can be used to calculate a panel’s power usage. 

Production ratio

The production ratio of a solar panel refers to the estimated output of energy a solar panel produces over a certain amount of time pertaining to the size of the solar system that is being used. The numbers displayed regarding the production ratio will always vary, particularly when it depends on how much sunlight your location receives. Still, the ratio will always adjust following the location factor. 


Besides the aforementioned qualities that you have to consider and begin to calculate when wanting to purchase solar panels for your home, there are many considerations you’ll want to factor in. One of the first things you will need to consider is the type of solar panel you’ll need that will prove to be most efficient for your property. You’ll want to look into three prime solar panels when factoring in considerations: thin film, monocrystalline, and polycrystalline. Something else you’ll want to consider is the amount of sun the area you reside in will receive. The shape and style of your roof will also make a difference in how well solar panels will work on your home. For instance, if you live in an area that receives substantial sunlight, you will only need many solar panel installation services.
