  • Suntech Power was awarded as the 2008 Solar Energy Development Company of the Year by Frost & Sullivan.
Struggle and Recovery:

Suntech was one of the leading companies back in 2008 but everything went out of control in 2011-2012. Suntech’s stock price dropped to under $1.00 due to this, they were facing bankruptcy.

During 2013, Suntech faced even more struggles due to defaulting on $541 million of convertible bonds, as a result the main branch of Suntech filed for bankruptcy in Jiangsu, China. Suntech also filed for Chapter 15 bankruptcy in Manhattan, NY in February 2014 for protection from US creditors.

Early in 2014, Shunfeng Photovoltaic International Ltd acquired Wuxi Suntech Power for $483 million (USD). With this takeover, Shunfeng is looking to expand their services from upstream solar products manufacturing to downstream power generation and making it a one-stop-shop for solar energy power needs. Therefore Suntech now has a solid financial backing with almost zero debt and are well-positioned to reclaim their position as global leader in the solar PV market again.

What Sets Suntech Power Apart:
  • Suntech solar panel has power production capabilities up to 325W.
  • Systems are tested against salt mist corrosion and have been approved for increased wind & snow loads.
  • They produce tier 1 solar panels with a 12-year product warranty, a 25-year performance warranty and a positive power tolerance of 0/+5%. Suntech solar panels offer up to 18.4% efficiency. As the solar panels are certified for corrosion-resistance, they are highly suitable for installation around coastal areas.
  • Suntech Power was the third solar manufacturer in the world to pass their test and has VDE certification.

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.
