3kW solar systems: Pricing, output, and returns

Thinking of installing a 3KW solar system / Axpert MKS 3KW Solar Inverter?

If you are not quite sure exactly how big this is, let alone how much it will cost you, I’ve got covered! Below, we determine exactly how large the 3KW solar system is, and looking at the amount of electricity that can be produced as well as the number of panels you need. We also take a look at the 3KW solar system costs and – more importantly – how much you can save.



Efficiency First!

Before embarking on any solar installation, regardless of size, always consider dropping the use of electricity as much as possible in advance – long term, this saves you money. With heating and cooling accounting nearly 50% of the water and electricity bills, take some time and money to upgrade the insulation, seal all the leaks around the windows and doors, and even button up your carolsbas (I was surprised how much energy is wasted there!)




Still have incandescent bulbs? Its trade for LED – Light color and quality are almost indistinguishable from Incandescents now. Still use this old fridge from your parents downstairs? Replace it with Energ efficient. Still use standard A/C? Replace them with DC inverter A/C.

Dollar-to-dollar, efficiency measures like those listed above are the cheapest way to save money on your utility bill – even cheaper than solar installation! The less electricity you use, the smaller the installation of solar energy can be. This lets you avoid spending money that you do not need, saving you more in the long run

Even before you go solar, think efficiency first!

How Big Is a 3 kW Solar System?.

Now let’s get meat from this article. Let’s look at the size of the 3KW installation of some different views. What does 3 kW actually mean? 3 kW (or kW) is just a measure of the amount of electricity the solar system can produce in a single moment. It’s just like how to use a light bulb to generate 9 watts of electricity. Instead of consuming energy like your light bulb even though your installation actually produces that amount of energy.


In perfect condition, where your installation is fully efficient and strong sunlight, installing your 3 kW will produce 3 kilowatt hours (kWh) of electricity in one hour (3KW x 1 hour = 3 kWh). In 5 hours, it will produce 15 kWh.

The proportion of households in the United States is about 900 kWh per month, about 30 kWh / day, so the installation of 3 kW will generate enough electricity to cover about half the needs of most people of electricity.

Unfortunately, although we do not live in a perfect world. In the real world, many factors actually drop the amount of electricity your system can produce: the shade, location, direction of solar panels, and even efficient wiring and your inverter. After considering the personal situation, the amount produced by the panels is likely to be lower. 

How many solar panels?

Most solar panels for residential facilities these days produce about 265 watts of power, although they range from 245 watts to a height of about 330 watts.

How many solar panels you need for a 3kW solar system depends on the wattage of your panels.

Let’s look at some examples:

250 watts plates = 13 plates (Mono Solar Panel Hisel Power)

265 watt plates = 12 plates (Q Cells Engineered in German 265 W)

310 watts plates = 10 plates (Talesun China)

You can see that, with an increased wattage plate (which means that it can produce more electricity at one moment), you need less panels. Obviously, the more efficient the plate, the higher the price. For most people, standard 265 watt panels fit the bill well, balancing performance and cost.


How much space do you take on my roof?

Residential solar panels are about 3 feet across 5 feet, totaling 15 square feet. This means the installation of 3 kW consists of 12 plate having a footprint of about 180 square feet. Although some people live in homes that are 180 square feet, it’s really not big (heck, it’s called a small house for a reason). Unless you live in a small house yourself, you probably will not have any problems fitting the 12 plates up on your roof.
