How Big and Costly Is a 15kw Solar System?

If you have talked with an installer or done some math to find out that the 15KW will be enough to cover your electricity needs, then it is great. But before installing, make sure that you have all the information about the 15KW solar panel. Here we will cover everything you need to know about 15KW solar panel and what does 15KW mean. And we will talk about the cost associated with it as well so that you will get a detailed idea.

Efficiency First

Before starting our discussion about 15 KW installation, we will talk about how you can save some money. Installing a 15KW solar panel is a great decision, and you will save so much money. But did you know that the energy efficiency measures will help you to save an extra amount of money? There are some energy-efficient measures you must take in order to stop energy loss in your home.

Start with covering your doors and windows properly, add insulation in specific areas, replace the lights with LEDs, and take other steps to reduce electricity use. If you don’t know where to start, then you can take the help of a professional who will take care of energy leaks and insulation levels. After completing these steps, you will be able to decide whether you need a small or big solar system for your home.

What Does 15kw Mean?

15 KW or Kilowatts is the amount of energy a 15KW solar panel can produce in a single instant.  To understand this properly, consider that you need 30 watts for your laptop charging, which means you will be able to charge 500 laptops with a 15 Kilowatt or 15,000-watt system.

But in the real world, you will not get exactly 15KW because there are many factors that can create efficiency problems. Some major factors are weather, cloud, rain, snow, dirt, and dust. Due to all these factors, you will get around 12.9 KW. But 12.8KW is also is a big amount of energy, and you can use it for your commercial or residential purposes.

How Much Space Does It Need?

15KW solar panel system will require 1,003 square feet, which is huge. If you are wondering how to fit them, then don’t worry. With typical string inverters, all the solar panels will be placed together and face the same direction and angle. Also, with a special inverter called a micro-inverter, you can optimize each panel separately over the roof with different angles facing different directions as well. But it can be more expensive than the common inverter, but if you don’t have enough space, then you can opt for it.

How Costly Is It?

The installation cost for the residential solar is $2.93 per watt. So, if you are going to buy a 15KW solar panel system to experience a better impact, you have to pay $43,950, which is expensive, but you can save money with some schemes. The offer depends on the location, so it would be wise to talk with the dealer. But once you have installed a solar system, then you don’t have to worry about electricity for at least 20 years.

Don’t forget about how much you are going to save on electricity bills as well. If you do the math, you will spend at least $52,870 in electricity bills in 25 years, but you can save all this amount if you have installed a solar panel. But don’t forget that you don’t have to pay $43,950 for the initial installation as you can get many offers that will reduce the price to 20-30%.
