14kW | 44 |
What Factors Affect the Size of the Solar Panel?
Before installing a full-fledged solar panel on your rooftop, you need to consider few crucial factors. Depending on these, you can accommodate your solar panel without any hassle. Let us assist you with your easy installation of a green energy source:
Roof Space
Depending on how much room you have to fill in for a panel, you can determine the size of your solar panels. If you have extra fittings such as vents or a chimney, you may need to get a solar panel that is smaller in size.
A 4kW will be suitable for most medium-sized roofs, and this will have a total of 16 panels to capture the solar energy source.
Solar Power Needed
It is vital to consider the amount of average energy you will need to power your house. You may have to consider the number of appliances you use daily. Such as air conditioners may require huge amounts of energy to operate. So this may require more kilowatts of energy for your solar panel to generate the desired electric power for your house.
Well, how do you go about this? The simplistic solution is to check your electricity bills and your daily consumption of energy at your house. This number will help you determine how big your solar panel needs to be.
Efficiency and Surface Area
So if you think a bigger solar panel will be more efficient than the smaller ones, then you are wrong. If you buy a higher-quality panel, it will produce a good amount of power even with a smaller surface area.
So if you have a smaller roof size, you can always opt for a premium grade solar panel, though it may cost you few extra bucks. You can easily manage with a 5.4 feet inches tall panel in a small roof and not compromise on quality.
Weight
You need to pay close attention to the weight of the solar panel, and the overall strength of your roof plays a pivotal role. Constituted of glass and heavy frames, each panel may vary in its weight.
Most common panels may weigh up to 40 pounds or even more, depending on the requirements. So a bigger solar panel will weigh more than usual and need a sturdy roof to accommodate it.
Do Residential and Commercial Solar Panels Have the Same Size?
At present, solar panels have become rampant for both residential and commercial purposes. They differ in size as well the number of panels per square feet area.
Most residential panels have a smaller surface area size to adapt to the roof space and aesthetic appeal. Also, they come in sizes approx. 65×35 inches.
Adding, for commercial purposes, the size of the panel will be greater extensively and may measure around 77×39 inches.
Residential solar panel systems have become a rage now, and more and more are shifting to this renewable energy source.
Backed with advanced technology and flexible features, the installation of solar panels has become easier than ever.
Expert help from your local installers will help you figure out which size is ideal for your rooftop. Since panels are readily available in varied sizes today, it will be best to consider all the factors to get hands-on an efficient solar panel system.
How Big are Portable Solar Panels?
Sometimes you may require smaller solar panels for remote or mobile use. Such panels are commonly found on boats, RVs, street lights, etc.
While standard solar panels are traditionally 60 or 72 cell panels, you can find smaller panels in different sizes.
Selecting the right portable solar panel for your mobile use requires you to assess the space available to you and figuring out how you can make the most of the limited area.
Talking about RVs and boats, most people pick standard 12-volt or 24-volt output. Full-sized panels can get a little too much in such places, leaving no space to mount the panels.
How Does the Size of a Solar Panel Affect Its Cost?
The cost of setting up a solar panel system is determined by how much electricity you wish to generate. Typically, bigger systems cost more since you’ll require more equipment and labor, and vice versa.
When you use solar panels to generate energy, you receive an amount known as the federal solar tax credit.
In addition, certain states and local governments offer other incentives, such as rebates, that can reduce the cost of installing a solar panel system. The main purpose of offering such rebates is to motivate people to switch to cleaner energy sources.
Here’s a quick look at the average cost of solar panels based on the size of the system.
System Size | Cost Before Tax Credits | Cost After Tax Credits |
---|---|---|
2 kW | $5,620 | $4,159 |
3 kW | $8,430 | $6,238 |
4 kW | $11,240 | $8,318 |
5 kW | $14,050 | $10,397 |
6 kW | $16,860 | $12,476 |
7 kW | $19,670 | $14,556 |
8 kW | $22,480 | $16,635 |
