Why Independent Energy Advice Is Important Before Investing in Solar, Battery Storage or EV Charging

Independent advice provides an objective assessment of the project, helping customers understand the true financial and operational impact, identify potential risks and ensure the proposed solution delivers the expected return over its lifetime.

Investing in solar, battery storage or EV charging infrastructure can represent a significant capital commitment and can have a long-term impact on a business’s energy costs.


Trans Tasman Energy Group (TTEG) can independently assess the proposed project and help determine whether it is suitable for the site, taking into consideration the customer’s existing electricity usage, demand profile, operating hours and future energy requirements.

  • Validate the expected ROI – Independently review the project’s financial assumptions, including expected savings, energy production, utilisation, operating costs and payback period, to determine whether the projected return on investment is realistic.

  • Assess equipment quality and warranties – Review the proposed equipment, manufacturers, product specifications and warranty terms to help ensure the customer understands what they are purchasing and the level of protection provided over the life of the project.

  • Assess the total cost of the project – Consider installation, ongoing maintenance, replacement costs, network impacts and other potential costs that may not be included in the initial project proposal.

  • Consider the project as part of the broader energy strategy – Ensure the investment works alongside the customer’s existing energy contract, network tariffs, consumption profile and future energy requirements.

  • Understand the impact on electricity bills – Model how solar, batteries or EV charging will affect current electricity consumption, demand and ongoing energy costs.

  • Understand the impact on future energy contracts – Assess how changes in consumption and demand may affect future electricity contract pricing and procurement requirements.

  • Identify trusted suppliers – Help customers identify reputable and established suppliers and installers with a proven track record, appropriate experience and suitable product and workmanship warranties.


For businesses considering solar, battery storage or EV charging, independent advice can help ensure the investment is assessed on more than the upfront price or projected savings, with consideration given to the full cost, operational impact and long-term energy position.
