What are the Factors Affecting Solar Panel Installation Costs?

Factors Affecting Solar Panel Installation Costs

The number of solar panels to install in your home largely affects how much you will be charged. Here are other aspects to consider when budgeting your solar power installation cost.

1. Quality of solar panels

Check brands such as Suntech, SunPower and JA Solar. They have varying prices which can impact your solar panel installation cost.

Identify how much power you need to generate to determine what quality of solar panels you are buying. Always go for products that offer the best value for money, which is not necessarily the cheapest.

Note: Ask Clean Energy Council accredited installers for recommendations to help you determine what type of solar panel would suit your property, budget and lifestyle.

2. Roof condition

Working on high-pitched roofs may entail greater risks, thus influencing the cost of installing solar panels. Access difficulties and installation complexities affect how installers charge for labour.

The use of scaffolding and other safety equipment may also add to your expenses. Clarify these terms with your prospective solar energy installation specialist to know what to expect.

3. Added components

Initial inspections are done to carefully determine what framing structures and mounting systems will fit your solar panel installation needs. In some cases, special frames are installed to secure house solar panels.

For new installations, electrical components such as wires, cables, switches and circuit breakers are required to accommodate additional power units. A licensed electrician can provide you with quotes enumerating labour and material costs.

Note: Post your installation job on HIREtrades and receive up to three quotes from local system designers and installers with zero fees.

Replacing Solar Power Components

With proper care and regular maintenance, most solar power systems last for 10 to 25 years. This varies greatly depending on the quality of solar panels, storage batteries and inverters installed. As time passes, solar power systems wear out and deteriorate.

Here are some tell-tale signs that would require replacement. 

  • Panels not running efficiently
  • Inverter(s) wearing out (Note: Most inverters have a lifespan of 10 years.)
  • Poor solar energy installation by unqualified installers

Clarify system efficiency with your solar retailer or installer to see if the products adhere to Australian Standards and local council requirements. This will save you money and avoid legal disputes in the long run.

If you’re replacing a few solar panels, have a professional installer check your existing system model and wiring placements. Only accredited, licensed electricians are required to replace solar panels for homes.
