5KW Solar System
5kW home solar system is a medium-sized system perfect for family homes, small commercial buildings, or larger homes with less energy usage.
Preparation: 14 Tier 1 solar panels, CEC approved 6kW inverter, installed by qualified retailers.
It is known that electricity bills are a great expense for many families in developed countries to deal with each month. Rising tariff costs have driven many homes, offices, and commercial enterprises to seek more cost-effective ways to power their places. 5 kW solar system is an excellent alternative and widely suited to many homes.
5 kW solar systems can provide more than the total energy consumption for the average home, making it an obvious, and relatively inexpensive way to reduce your energy bills.
Cost Estimate
Project Overview
5kW solar system, is it enough for my family?
5kW solar system is suitable for medium-sized homes with an energy bill between $400-$600 per quarter. Determining household energy needs by the number of people in your home can be unreliable, but as a rule of thumb, a 5kW solar energy system is best suitable for an average 4-person household.
It can comfortably supply 10-15 kWh daily for an average household of four to five occupants. If your home does not need to use the air conditioning, a heated pool, or regularly uses large home appliances, then a 5kW energy system should cover your usage needs.
What's the number of panels on 5kW solar system?
The number of panels for a 5kW residential solar system depends on the wattage and size of the panel. 5KW home solar system produces 5000W of power. So, the number of panels, multiplied by the wattage of each panel, needs to equate to 5000W. On average, there are between 14 – 20 panels in a solar system, depending on the output of the solar panels themselves. The higher each panel’s wattage, the fewer panels a 5 kW home energy system will require.
Frequently Asked Questions
Most frequent questions and answers
How much roof space is needed for a 5kw solar system?
If your home is suitable for solar, you’ll need a roof space between 25 – 35 m² to install a 5kW solar home system. Solar panels come in various sizes, depending on the manufacturing company, as we mentioned above.
Sample solar panel measures 1.7m x 1m in size and consists of 14 to 20 panels, based on the wattage. You may plan to install a solar system with 370 W per panel. In this case, a 5KW system will consist of 14 solar panels.
However, to determine if your roof has enough space. Firstly, you need to know if your roof is suitable for solar, including if it has multiple orientations or is made of hazardous material.
How long can 5 kW solar system last?
High-quality 5kW solar systems come with a warranty of at least 15 years, and an estimated lifespan of 20 years. You can extend the longevity and performance of a solar system through proper maintenance and cleaning.
The report by the National Renewable Energy Laboratory (NREL) in 2012 reveals that solar panels degrade by 0.8% per year on average. As long as external forces don’t damage the panel, the system will continue to serve you for between 25 to 40 years.
You should also consider inverter degradation. Residential solar inverters have shorter lifespans. They normally last about 10-15 years (with 5-to-10-year-warranty). This means you will have to replace your solar inverter sooner than the actual panels.
How Much Power Does 5KW Solar System Produce?
5KW home solar system generates 21kWh of power per day on average. The actual amount a 5kW solar system will produce on a given day is impacted by the average sunlight received in your area, the weather, and the orientation of your solar panels.
A peak sunlight hour is the equivalent amount of sunlight received during the middle of the day if solar panels are exposed in the sun during midday for 4.2 hours. 5kW system will produce 5KW of power for every peak hour, so over 4.2 peak sun hours, a system will generate roughly 21kWh(4.2*5kW=21kW)
The amount of direct sunlight available in your location is the primary concern in calculating how much power your solar panels will generate, as the weather and climate will impact the total sunlight absorbed by the panels. For example, clouds or overcast weather can drastically reduce a system’s production.
What Is The Payback Period For 5kW Solar System?
This figure however depends on where you live, your cost of electricity, your feed-in tariff, and your daily energy usage.
To determine how long it would take to pay off a system, you must calculate the total monetary value of the energy produced by the system on an annual basis, and divide the cost of the system by this figure.
You can do this by figuring out what the cost of power is, how much you will export, and use in the home, and what your daily savings are.
