Additional Installation Costs Guide 2022.

Wouldn’t it be great if the advertised price of a particular solar package, battery system or EV charger were all you would ever need to pay? The good news is that for 60% of homes, the advertised price will likely be the final price. However, many homes have imposing factors requiring more significant installation hours than standard homes or additional specialised products to ensure the system meets local energy requirements.

PSW Energy has the three singles rule regarding base advertised prices. Single-phase, single-level and single roof. The three singles rule ensures the ability to promote competitive prices fair to all parties without complicated details. Let’s expand on this a little more.

 

To assist in keeping the additional solar costs as transparent as possible below is the PSW Energy Additional Solar Installation Cost Guide 2022. The listed prices are in order from the most common upgrade costs.

Tiled roof upgrade costs.

A standard PSW Energy solar package is equipped with Tin roof mounting hardware. To accommodate a Tile roof, more expensive robust stainless steel brackets are required to accommodate the profile of the tile without impacting the roof’s waterproofing. There is also an additional time component for solar technicians to fit these more complex brackets. Tin roof brackets are far simpler by design and therefore cost significantly less. Furthermore, as each tile profile is unique, standard tile brackets may not accommodate more unique designs and this cost may vary.

The above table should be used as a guide only. Certain tile profile requirements may affect the cost.

3-phase inverter upgrade costs.

A standard single-phase home has one active line (1-phase) coming to the home from the grid, 3-phase homes have three active lines powering the house from the network. This is similar to an industrial and commercial power supply to operate more heavy-duty equipment. As such, to accommodate bigger loads, the cost increases from a manufacturing and installation perspective with solar power supplies.

If you have a large house or big-load electrical appliances (i.e. specific pumps, large air conditioning systems etc), there is a high chance your home is 3-phase, and you’ll need a 3-phase inverter. 

Frequently Asked Questions; 3-phase.

3-phase solar inverters are more expensive from a manufacturing level and require additional costs to purchase. Further more, upgrading more than the inverter alone must be considered as additional costs exist within 3-phase cabling, 3-phase isolators, and 3-phase circuit breakers.

Multi-level installation costs.

As multiple-level homes or properties take many shapes and forms, a $500 additional cost is a starting indication only. Each property must be assessed/quoted on a case-by-case basis as the increased cost may be required based on varying degrees of installation difficulty.

Frequently Asked Questions; Multi-level.

Additional installation costs exist for multiple level installations or properties where the gutter line is higher than 2.2m for varied reasons;

  • Time.
  • Employee safety – Worksafe laws.
  • Additional cabling requirements.
  • Safety barriers.
  • Lifting equipment.

Even if a solar array is being installed on a single-level roof of the house, multi-level installation costs are required. As the electric cabling work is often the most exhaustive portion of any installation, this additional cost recovers the extra time and materials required to extend cabling through the multi-level section of the home.

Split solar array costs.

Some roof areas are greater than others. Installing solar panels on one singular roof face is the simplest and most cost-effective installation method. Where solar panels are required to be split across multiple roof faces (see below image) of a home to achieve the desired kW capacity, additional cabling and roof work are required. Additional split solar array costs start from $200 per split from an initial solar array

Frequently Asked Questions; Split Array.

This scenaio will require a split solar array charge as the additional material and labour costs are incurred through having to re-enter the roof space, create additional penetrations in an alternative section of roof and install a supplementary solar array irrelevant of distance.

Energy consumption monitor package costs.

Basic solar energy systems within the PSW Energy range come standard with WiFi-connected production reports and service messages available to customers from convenient iOS & Android web apps. However, what’s truly beneficial for many is visualising the energy coming into and leaving the property (energy consumption and energy export data) alongside solar production data. Understanding such facilitates a greater understanding of one’s energy-saving potential and the ability to fine-tune selected appliance operation to better utilise the available solar energy. This can only be viewed by installing an energy consumption monitor at the same time as the solar energy system.

Existing system removal costs.

Heard the phrase “it’s better to reuse than recycle”? Removing an existing solar energy system and ensuring the products are repurposed in an environmentally sustainable method is how the world benefits from your old solar energy system. PSW Energy follows an environmentally and humanitarian conscious approach ensuring your existing solar energy system can be repurposed in alternative global regions where renewable energy subsidies are obsolete or solar is not so affordable. 

 

The result ensures life’s basic expectations, such as clean drinking water can be pumped from the power of the sun.

 

The cost is minimal to ensure your panels don’t end up in landfills and are sustainably repurposed, the cost is minimal; $150 for systems up to 15 panels. $10 per panel thereafter.

Switchboard upgrade costs.

Another significant variable where it all depends on the extent of the upgrade requirement. 95% of switchboards have a sufficient amount of available space to accommodate solar. However, if your switchboard is looking a little full, then upgrade work may be required. Common switchboard upgrade work cost averages below;

Backup power supply costs (blackout protection).

Batteries have risen to affordability by scaling back the primary purpose. Modern consumers now expect continued energy savings from their solar panels after the sunsets as the primary purpose of the modern solar battery, this is referred to as “Load Shaving”. 

 

However, if you live in an area prone to frequent grid power outages, ensuring a solar and battery system can operate as an emergency/temporary backup power supply makes sense for selected loads. To facilitate this takes additional equipment and wiring to ensure a backup supply that meets your expectations and won’t cause harm to anyone working on the grid. With additional complexity comes the additional cost of equipment and time.

Multi-level installation costs.

As multiple-level homes or properties take many shapes and forms, a $300 additional cost is an indication only. Each property must be assessed/quoted on a case-by-case basis as the increased cost may be required based on varying degrees of installation difficulty.

Frequently Asked Questions; Multi-level.

Additional installation costs exist for multiple level installations or properties where the gutter line is higher than 2.2m for varied reasons;

  • Time.
  • Employee safety – Worksafe laws.
  • Additional cabling requirements.
  • Safety barriers.
  • Limited access.

This depends on the cable path or certain technician access requirements. Once access to an area of the dwelling is required to a roof region with a greater than a 2.2m gutter line, a mult-level installation cost is applicable.

EV Charging.

3-phase (22 kW charging) costs.

Base electric vehicle charging outlet costs facilitate a single-phase supply to the outlet. Even though the EV Charger may be capable of single or 3-phase without a product upgrade, additional costs exist in the form of time, cabling and sundry items such as 3-phase isolators etc.

 

If your property possesses a 3-phase power supply, taking advantage of 22 kW charging capabilities could be advantageous in reducing your electric vehicle’s charge time. 3-phase provisioning to your EV Charger starts from $200 per outlet.

Multi-level installation costs.

As multiple-level homes or properties take many shapes and forms, a $300 additional cost is an indication only. Each property must be assessed/quoted on a case-by-case basis as the increased cost may be required based on varying degrees of installation difficulty.

Frequently Asked Questions; Multi-level.

Additional installation costs exist for multiple level installations or properties where the gutter line is higher than 2.2m for varied reasons;
