5 Kw Solar Panel

5 kW solar panel package:

Increasing energy demand boosted sales of 5 kW solar power systems. 5 kW solar panels become the bestselling solar power system in Australia.

What Makes 5 kW Solar System?

20 x 250W Solar Panels

Usually 250W is commonly used solar panel size. 20 panels of 250w makes a solar array of 5000w (20 x 250w) which totals 5 kW solar panel’s output.

5 kW Solar Grid Inverter

Usually Inverter with 5 kW or higher input capacity is used to meet the output of 5 kW solar panels. Solar inverters are available in different sizes to meet up design requirements in consideration of local laws.

Solar Panel Mounting for 5 kW Array

Every Home roof is different, means we need different mounting brackets to ensure panels fitted well on roof. Major solar installers use special mounting brackets to install solar panels securely on roof. These brackets are specially designed to hold panels on roof without any damage to roof or structure.

5 kW Solar System Installation

Every solar system needs to be designed according to site.CEC accredited Installer Design and install your 5 kW solar system to ensure you get best output.

What Components Included in 5 kW Solar Panel System?

Many of you quite often think about how many panels you need. Or what major components solar panel system do include?

Main components for solar panel installation are

  • 20 x 250W Solar Panels
  • 5 kW or bigger Solar Inverter
  • Solar Mounting

Other items will be included with standard installation as an accessories such as cables, Dc and Ac isolators, monitoring devices and labels.

How would 5 KW solar panel system connected?

When we are connecting multiple solar panels, you have few combinations on how to connect solar panels. You can connect them in series, parallel or a combination of both.

It actually depends on how you are getting the best out from 5 kW solar panel array.

Solar Panels Connected in Series or parallel

In general grid connected 5kW solar panel systems would be connected in series.

How much Power 5 kW solar system generate?

Installing a 5 kW solar panel system is a great way to save on energy bills for midsized home. 5 KW solar panel system can give immediate impact on family’s budget, saving up to $1600 per year. Family can harvest savings according to their usage patterns, property location and orientation.

In optimum conditions 5 kW solar panel system would generate approx. 19.5 kWh/day.

Power output assumptions for 5 kW solar panel system

5 kW solar panel system can generate 19.5 KWh every day in sunny day with north facing solar panels. This is an annual average as per clean energy council guidelines. In summer it will generate more due to longer sun hours where less in winter.

Rebates available on 5 kW solar panel system

Under the Small-scale Renewable Energy Scheme, eligible solar power systems are entitled to a number of small-scale technology certificates (STCs), depending upon the size of the system and the region in which it is installed. The table below gives an example of the value of the STCs for different sized systems in zones 1, 2, 3 & 4 in Australia. The zones are shown on the subsequent map.

Solar Rebates Zone Map

In Newcastle, property in any location falls in Zone 3. 5 kW system in zone 3 will generate 103 STCs. If we take current prices of STCs ($38) in consideration, a 5 kW system would be backed by $ 3914 government rebates.

Cost of installing 5 kW solar panel system

Solar sector is highly competitive, with a large numbers of business offering different 5 kW systems with different designs, components, levels of Quality and performance.

5 kW solar power system sold around $4500 -$7000 fully installed*.


How long before a 5 kW system pays for itself?

This is totally depends on many factors such as price you paid for 5 kW solar system installation, panels array orientation, your usage patterns and weather.

Solar owners can reimburse their investment in 3-5 years considering they have installed panels in optimum direction.

Returns on investment on 5 kW solar panel system

Each site is different. Our installers needs to customize the installation according to roof size and roof type. As mentioned earlier 5 kW solar power system can save approx. $1600 every year.

How to ensure solar products are safe?

All accredited solar installers must use products that meet Australian Standards. The Clean Energy Council has compiled a list of approved products including solar PV modules (panels) and grid connect inverters that meet these standards. In order to qualify for government incentives for the solar PV system, installers must use approved equipment listed by the Clean Energy Council.Click here to browse approved solar PV inverters.

How to ensure the installation up to standards.

Every 5 kW solar panel system installation carried out by an accredited installer is required to meet the following Australian Standards:

AS 4777 Grid-connections of energy systems via inverters

AS/NZS 3000 Electrical wiring rules

AS 1768 Lightning protection

AS/NZS 1170.2 Wind loads

AS/NZS 5033 Installation of photovoltaic (PV) arrays
