how to discover how many solar panels are needed for your home
So, you want to install solar energy at home.
You have done some homework, checked some solar panels and visualized how they look (or on)
Your house or office
Now, you\'re asking, \"How do I know how many solar panels I need?
\"Here\'s how to determine how many watts you need, tailor-made specifically for your home, and how to get that information, and use that information to know exactly how many solar panels you need.
You have to start by determining how much energy your family has consumed.
You can\'t know the exact number of solar panels you need until you calculate them accurately.
Take a closer look at your old electricity bill.
Determine your average energy usage per month, ideally a full year to take into account seasonal changes.
Remember the total amount of kilowatts per hour (kw/hr)
Your home consumption
To get the average kw/hr you need for your home, simply divide the total kw/hr by the total number of days of the billing period you are looking.
The billing period for most utilities is 30 days.
By doing so, you will know how much kw/hr your home solar system needs every day to meet your solar needs.
If you do this all year round, you will know when your average daily usage and consumption may peak.
This is important information to determine how many watts your family needs.
You must confirm that your power company will be happy to buy back the additional solar energy made by your solar system.
While power companies rarely really pay for the extra power you provide, most people are happy to buy back the power within the scope of your current bill.
They will accept it after that, but only if they don\'t actually pay you.
You need to look at the position of your local company on this matter.
If you\'re the one who chooses not to leave completelygrid (
By the way, this is perfectly reasonable! )
You haven\'t bought any batteries yet to store the extra solar energy, then you will sell your house one day --
Provide solar energy to utilities. In the U. S.
Under the law, the power company must pay any fees you pay them.
At other times you will not generate enough solar energy and you may pay for energy for them.
Anyway, you want to get your energy bill to zero for a whole year.
In other words, you want to have the right amount of solar panels, not too much, not too little.
Few energy companies (if ever)
If you are over-doing, give you money on your own initiative. supply them.
So instead of building solar energy for your home system, it will produce more solar energy than you might use.
You want the system to generate enough money to keep your bill zero.
To determine how many watts of solar panels you need, you have to figure out how many hours of direct sunlight your home solar system will receive.
In short, on average, how many hours of direct sunlight will your home absorb in any year?
There are several ways to solve this problem.
The \"hard road\" is the time to take the time every day to pay attention to the Sun\'s exposure to the roof, where you are considering installing solar panels.
Let\'s face it now!
Since you may not want to keep this laborious everyday trivia for a whole year, this approach is almost certainly completely impractical.
If you have a tracking system for your home solar system ,(
Built-in ability to move and track the Sun)
The number of hours of sunlight received on the roof is different from the number of hours of direct sunlight.
Because the light of the sun shines on solar panels from many different angles (
Not only when it\'s right angle to your roof)
You will find that your calculation will be different.
In general, most houses enjoy an average of about 5 hours of direct sunlight throughout the year.
This is a rough approximation, so don\'t get angry with me if you get less energy than this article suggests! (
You can always go back to your daily reading if you wish! )
If you live in the United StatesS.
You want to get a more accurate assessment and look for the average regional value of your local area.
On August 2004, the Florida Solar Center submitted a study entitled \"geographic changes in photovoltaic power generation potential of roof dwelling homes in the United States\" in which they tested systems across the United States for home 2 KW solar power generationS. A.
They read in more than 200 locations in the United States. S.
Studies have shown that an average roof system of 2 kw will be utilized between 5 and 8.
5 kw/hr per day throughout the year.
So use the low end of the scale, a 2-
Kw system can see 5 hours of sunshine every day.
The Kw system is expected to enjoy an average of 10 kw/hr solar energy per day throughout the year.
Think about how you plan to use solar energy at home.
Do you want to leave completely? grid?
This will create greater demand for solar energy in the home system.
Also, be aware of any potential problems, such as the fact that tall trees block the sun from solar panels.
If your average power consumption is 600 KW/hour per month and you are sure that your power company has a billing period of 30 days per month, then you can know that your energy consumption per day is 20 kw/hr (i. e.
600 kw/hr divided by 30 days per month).
Using the Florida simulation data found in the graphic \"geographic changes in photovoltaic power generation across the United States\"S.
\"We can see, for example, that Florida\'s southernmost estimate is 7.
Based on the use of 2kw roof photovoltaic system, 5 kw/hr.
So we can know that the average income of people living in southern Florida is about 3.
Direct sunlight 5 hours a day.
If you know that your home currently uses 20kw of electricity every day (
Aka 20,000 W)
So let\'s say you know your average income is 3.
Five hours of sunlight a day to produce the total amount of solar energy you need, then the solar system you need must contain about 5 hours, 700 watts of solar panels, to produce the right amount of solar energy that your home usually uses every day. So don\'t delay.
Nothing is louder than action.
