Key takeaways


he size of solar panel systems can vary hugely. Commercial solar systems are physically much larger than solar systems used for residential purposes. However, when considering purchasing a solar panel kit for your home, keep in mind that residential solar systems can also come in a range of sizes. The smallest and, at the same time, the most affordable option is a 1kW solar installation. But is it worth buying a 1kW solar system, or is it too small to be effective? Take a few minutes to read this article and discover more about solar panels 1kW.

Understanding the concept of a solar system

What is the difference between the terms “solar panel” and “solar system” or “solar installation”? Basically, every system comprises some elements, and a solar system is made up of solar panels and additional equipment called Balance-of-System equipment. A solar panel is the main component of a solar system, as it is responsible for capturing and converting the energy from the sun into usable electricity.

The larger a solar system is, the higher its price will be. So, if you're looking for a cost-effective way to get started with solar, a 1kW solar kit is the most suitable solar option. Solar panels 1kW won’t require a significant initial investment, making them an affordable option for many homeowners.

Types of 1kW solar installations: on grid, off grid and hybrid solar systems

Solar systems differ not only in size; they can also be on grid, off grid, and hybrid. An on grid solar system is connected to your utility company's network, while an off grid solar system is completely independent. A hybrid solar system is a combination of both. Every solar installation, including a 1kW solar system, can be any type. However, it is to be noted that a completely autonomous solar system requires more capacity than network-connected solar equipment.

Can you actually buy a 1kW panel? How many solar panels 1kW setup needs

Don't waste your time trying to Google search for the price of 1 kw solar panels – such panels simply don’t exist. A 1kW solar installation consists of several modules. The number of solar panels 1kW setup requires depends on their wattage; if you have 5 panels of 200 watts each, you'll get the desired 1kW system output.

What is the average price for a 1kW solar system in the United States?

Since a 1kW solar system is not very popular in the U.S. compared to, for example, 6 or 9 kilowatt solar systems, it is pretty challenging to make a comprehensive price comparison for 1kW solar equipment. Below, you can see how much your solar panels 1kW will cost if you choose Renogy solar panels, which are representative of the 1kW segment but are slightly less expensive than the average solar module on the solar market. The prices for 1kW solar are expressed both in $ and  $/watt.

Wattage Number of solar panels for 1kW Total wattage (1kW or appr. 1kW) Total initial expenses for solar 1kW ($) $/watt in a 1kW solar system
50 Watts x 20 1kW $1,499.98 $1.49
100 Watts x 10 1kW $999 $0.99
200 Watts x 5 1kW $1,399.95 $1.39
320 Watts x 4 1,2 kW $1,299.99 $1.01
450 Watts x 2 0,9 kW $899.99 $0.99

How to calculate the space you need for your 1kW solar installation?

In addition to the 1kw solar panel price, there is another crucial factor to consider when choosing a 1kW solar system, and that is the space required. To calculate how much space you’ll need, take the size of your solar panels 1kW. By illustration, let it be the following typical dimensions of a 100-watt solar panel: 1044 x 508 x 35 mm (41 x 20 x 1.4 inches). With this wattage, you will need 10 panels to get 1kW. If you create two rows of the same size, then, for 1kW, your total height will be 2088 mm, and your total width will be 2540 mm. The total size of this 1kW solar installation will be 5,3 m2.

Capabilities of 1kW solar: Can a 1kW array power your house?

To define whether it is worthwhile to set up a 1kW off grid solar system, let’s look at the basic statistics. The electricity consumption of an average American home is around 877 kWh a month, or 29 kWh a day. Even if you live in a sun-rich region like California, a 1kW solar system will generate only about 5 kWh per day. And if you live in a cloudy area like New York, 1kW photovoltaic array will produce just 3.5 kWh daily. So, most likely, to run your house entirely on solar, you will need a more powerful PV array than 1kW. Still, a 1kW solar installation can satisfy a part of your energy needs, and it may be all you expect from your 1kW PV modules.

A summary of the pros and cons of solar panels 1kw

While 1kw PV systems can offer numerous benefits, it is essential to understand both the pros and cons before making a decision. Below, we will explore the advantages and disadvantages of 1kw setups to help you determine if it is the right choice for your home.

A 10 kW solar panel system typically consists of around 30-40 solar panels, generating approximately 10,000 watts of electricity under optimal conditions.

Benefits of 1kW solar panel installations

Solar setups with only 1kW capacity are cheaper

One of the main benefits of 1kW solar panel installations is a lower price than larger solar setups. Not only the number of solar panels 1kw system requires is smaller, but also less labor and fewer overall materials are needed for the installation process. Additionally, these installations also have lower maintenance expenses and a shorter payback period compared to larger solutions.

Less extensive solar arrays are easier to install

1kW solar panel installations are an excellent option for those with limited rooftop or ground space because they do not require as much space as larger setups. These arrays typically consist of around four to six solar panels, which can easily be mounted on a small rooftop or placed in a sunny area of your yard.

Drawbacks of 1kW installations

1kW installations may not produce enough solar power for larger homes

A potential issue with 1kW solar panel installations is that they may not produce enough electricity to meet the needs of a household or business. Solar panels 1kw setups are generally smaller in size and therefore produce less electricity compared to larger solar installations.

Small solar systems keep you dependent on the utility power

Even if you have a 1kW solar system installed, you will still depend on the utility network for some of your energy needs. This can be frustrating for those looking to completely eliminate their reliance on fossil fuels and become more self-sufficient.

Key takeaways: is a 1kw solar system a good choice for going solar?

A 1kW PV installation might be perfect for your household, in case it is located in a very sunny area, and your budget is limited. It is generally not recommended to install a 1kW off grid solar system, as even in places with lots of sunshine, you will need more power than a 1kW solar setup can generate to get independence from the state electric network. On the other hand, a 1kW solar system is a good budget way to start your green lifestyle and reduce your electricity bills. But remember that proper orientation and tilt angle are essential for good efficiency results when installing a 1kW solar array.

Proper installation, regular maintenance, and compliance with safety standards are crucial for mitigating the risk of solar panel fires. Homeowners and businesses considering solar installations should work with reputable contractors and ensure that their systems are installed correctly and equipped with appropriate safety features. Stay informed about solar panel fire risk.
