Costco’s Sunrun Solar PanelsCostco Solar Panel Review 2020

Costco’s Sunrun solar panels hit the Aussie shelves this year but how do they really stack up in price, quality and warranty? Here is our review of Costco’s Solar Panels 2020.

How Does The Deal With Sunrun Solar Work?

So, how does the deal work?

  1. You are given a complimentary Sunrun solar consultation.
  2. You are given quoted costs.
  3. Sunrun will send out an installer to get the system fitted to your home.
  4. You get a 10% Costco shop card on qualifying Sunrun equipment.

*Note: The 10% Costco Shop Card only applies to customers purchasing outright. Using financing options means you for-go the cash card rewards.

Price of Costco Solar Systems

Price varies substantially depending on the system size required. However, Sunrun will be looking to bill between $20,000 (4kW)- $40,000 (8kW) plus additional ‘equipment costs’.

When comparing Sunrun’s price points against the average cost of solar within Australia, Sunrun’s price is extortionately high.

The high price point however comes down to Sunrun’s use of ‘cutting-edge technologies’ and high-quality products.

Warranties Of Sunrun Solar

Although Sunrun and Costco are partners, warranties for the panels can only be claimed though Sunrun not Costco.

Sunrun’s solar panel warranty offers 10 years cover for workmanship and 15 years cover for roof penetration, which can be found on their main website.

To Sum Up

If your keen on the idea of shopping for solar panels while you are shopping for your eggs then the Costco solar option might just be for you.

Although the 10% Costco gift card reward may sound like an enticing offer, Sunrun solar prices are extremely high for the average renewable loving joe.

The good thing about Sunrun’s partnership with Costco though is that quality is not compromised. You may be paying top dollar but you are also receiving top quality.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
