People take all kinds of actions these days to make their lives more comfortable and affordable at the same time. However, increasing your comfort and convenience can often mean paying a hefty sum. Therefore, comfort doesn’t come cheap most of the time.
However, a solar power system deviates from the norms. It can offer you more comfort while reducing your expenses. Although there is an initial investment for installing a solar system in your home, the long-term benefits of reduced bills can give you a glorious return on your investment.
Therefore, getting a solar system is a brilliant choice. But you might have to go through some stressful planning before becoming more energy independent.
With the help of the details below, you can understand how many solar panels you need for your home. Not only that, you can understand a lot more that can help you plan a solar power system for your home.
To properly answer the question in your mind, you will first need to calculate your home’s current electricity usage. After doing that, you will calculate the number of solar panels for your home. So, let’s get started.
Considering that your electricity usage varies from month to month, you need to calculate your annual electricity expenditure. Then divide this expenditure with per unit electricity rate. This will give you the annual units used by your Property/Factory. Follow the next step if you know your annual electricity unit requirements.
Not everyone who switches to solar power powers 100% of their home with solar energy because some technical aspects are involved. In Pakistan, every home’s electricity load is sectioned and we can only install 1.5 times of that sectioned load. Normally, one Kanal home can install a solar system with a potential of 15KWp.
Therefore, if you decide to get 75% or 80% of your annual electricity usage from solar panels, simply divide the percentage by 100 and multiply the figure with your daily electricity usage.
In Lahore, use the following formula to calculate the power of the system required for your annual needs.
1Kwp in Lahore will generate 3.8 units per day, hence 3.8 * 365 = 1387 units annually
You can now divide your annual units calculated in Step 1 with 1387 to get the strength of the system required to fulfil all your electricity needs.
Now, you will finally get the answer to the question. To get there, convert your Kilowatt power into watts by multiplying it to 1000 and then dividing it by the panel size.
Take 520-watt JA Solar, panels, for example, you get: 6940/520 = 14 solar panels for your home
In case you’re having trouble finding how many solar panels you need for your home, you can contact the experts at RS Energy for Solar Solutions in Pakistan. They can give you the exact number, whereas this formula gives you an estimate.
Unfortunately, calculating the number of solar panels you will need in your home is not just about inputting some figures in a formula. That’s because there are a few factors any seasoned professional will consider while thinking about how many solar panels at home need.
While there can be a few factors to consider while living in Pakistan, the following three are the biggest.
The bigger your house is, the chances are you are consuming more electricity than someone who has a much smaller home. However, does your property have enough space to fit the required number of solar panels to power your home?
Still, some factors can affect this as well. 1 Kanal house with energy-efficient appliances, lighting, and other devices may consume less electricity than an old 12 Marla home with older and less efficient devices.
Fortunately, you don’t always need to have solar panels installed on the top of your roof. If your house has enough space, you can discuss other options with the experts at RS Energy by Zahid & Company.
Just because you’ve got the right number of solar panels that should generate enough to power your home on paper, doesn’t mean the solar power system can do the job. The reason is the availability of sunlight in your area and your home.
Different areas get different hours of sunlight during the day. The sunlight directly available to your home may be different because of neighbouring buildings, landscape, and other factors.
Typically, the product of the average amount of peak sunlight you use in the above calculations only gives you an estimate that may or may not be close to the actual figure. When you work with solar power experts at RS Energy by Zahid & Company, they can handle everything and provide you with more accurate data and quality systems.
If you were wondering why solar panel quality matters a lot, it’s because of their ability to convert sunlight into DC electricity or their efficiency.
Solar panels of unique qualities have differing wattage per panel. You might find 520-watt solar panels and 450-watt solar panels. The size, efficiency, and type of solar panel can also affect the wattage you get per panel. The inverter you use in your solar power system can also have a major effect on the final amount of electricity available for your home.
Because the number of variations and quality is enormous, it’s not simple or easy to say which panels or how many solar panels are right for your home in Pakistan. Therefore, schedule a meeting with the experts at RS Energy for specifics relating to your unique needs.
Finally, the number of people living in a house also matters, not just the size of the property. The more people are living in your home, the more energy your panels will need to produce. Therefore, you may need more solar panels.
