Users with higher energy consumption face unbearable power bills often. The increasing electricity prices have forced a larger community to shift to solar energy production. Hence, depending on the varying requirements of different users, the market has launched various alternatives like 3,6, 8, and 10kW solar systems.

Studies show that users with small businesses and extensive household requirements are rapidly investing in solar systems. Since power is the driving force of every setup, many questions about installing an 8kw solar system kit come into the minds of the buyers. The following excerpt addresses all those uncertainties.

What Budget Do You Need for Setting Up An 8kW Solar System?

Let’s begin by analyzing the most fundamental consideration for an 8kW solar system. Usually, 8kW solar systems cost between 6 to 12000$. However, the price of the complete setup significantly depends on other factors like installation and equipment costs. The expense of installing an 8kW solar system in Australia relies on the following factors.

  • The number of installed panels
  • The required output capacity
  • Quality of the panels
  • The battery setup

What Kinds of Paybacks It Offers, And What Is Its Estimated Duration?

Solar setups in areas with more sun time have a higher savings curve than cold and misty areas. Usually, an 8kW solar system neutralizes the initial expenses with 2.5 to 3.5 years. These systems save you around 3,500 dollars of electricity bills annually.

There are various methods to save costs using an 8kW solar system. Setting up a grid-operated solar system is suitable when you have low finances.

Solar energy can satisfy smaller needs like fans, lights, and bulbs. At the same time, heavier appliances like washing machines and air conditioners operate on the power coming from the grid. Later, you can upgrade the number of panels and completely go off-grid.

An 8kW solar system generates about 35kWh of energy. If your daily power consumption is lower than the generated power, you can sell the additional power to justify the initial expense.

What Are the Rooftop Requirements?

Rooftops are the best spot to place your 8kW solar system. However, it is essential to consider the maximum number of panels the roof can house. It depends on how much power you want to generate. Usually, 8kW solar system panels require 30 to 40 meters per square installation space.

What About Maintenance and Durability?

Solar panels don’t need maintenance and last for 25 to 30 years. Your 8kW system will still produce power after 30 years. But it will not be power efficient as the panels wear out over time due to heat and exposure. According to the National Renewable Energy Laboratory, solar panels wear out about 0.8% annually. So after 25 years, your 8kW solar system will provide 80% of its initial efficiency.

In comparison, the inverter devices require more maintenance. Usually, residential solar inverters require replacements after 10 to 15 years.

Final Verdict

An 8kW solar system is best for sizeable power requirements. However, since it is more expensive, it is best to analyze your energy needs before buying one. If you have energy consumption higher than 25 kWh, you can go for an 8kW solar system.

However, if you don’t have budget constraints, you can invest in a more extensive solar system as you can sell the excessive power.

Also, it is essential to note that the system’s power production depends on the light hours, the number of panels installed, and the daily consumption. The average payback time is 2 to 3 years, but it may vary slightly.
