5,000 Watt (5 kW) Solar System

The first thing most people do when they search for a 5kW solar system is to find out how much it costs.

There are various quality solar system products available on the market, so please be cautious before buying. -Don’t Buy A Cheap 5kW Solar System.

A good quality 5kW solar PV grid-tie system is very important for those who looking for easy-installation and free-maintenance.


How much will a 5kW system save me?

The amount you would save by installing a 5kW solar power system will vary depending on:

  • Your location: More sun, more power, you will get Greater savings

  • The amount you pay for power: Obviously the more you pay for power the more money a solar system saves you.

So although there is no one same answer for this question that will be true for everyone but we can calculate approximately and say the range of potential savings for a 5kW solar system would be from $800 to $1400 per year depending on your cost of power, different countries/areas savings will be different.

How many solar panels do I need for a 5kW system?

In the typical 5kW solar system, if each solar panel you choose is 290 watts of power—meaning you'll need like 18 solar panels in total and you will get a 5.22kW system.

If you use a higher wattage panel then there will be fewer panels in number, e.g., if you use a 350-watt panel then 16 panels would give you a 5.6kW system.

5kW Solar Systems---Solar Panels Part

Standard residential solar panels have been improving rapidly. Solar Panel now we offer 350/290Watt panels for the mono-crystalline type, and as technology improves we also will see high-efficiency panels for our customers. This means that for a 5kW Solar Installation, it typically includes 14 to 18 panels, either in series with a string inverter or as a 5kW Micro Inverter System powered by us.

Q: How much power will a 5kW solar system produce?
A: Assuming an unshaded south facing array a 5kW solar system will produce between 14.5 and 23 kWh per day on average across the year depending on the location where the system is installed. Customers can check their local sunlight situation or contact us we will help check and calculate and show you how much power solar panels produce for specific location.

Q: How many square feet of roof space will I require to install a 5kW solar system?
A: Depending on the exact efficiency of the solar panels being used-about 66 square feet per kW generated of roof space, meaning a 5kW solar system will require approximately 330 square feet of home roof space to be suitable for the installation of solar panels.

Q: Is 5kW the right size of PV system for my home?
A: The answer to this question depends on your installation location and your power usage.
