Pacific Energy Solutions - Off-Grid and Happy!

"It was a refreshing and genuine pleasure to work with Perry Hutchinson on the solar electrical upgrade of our holiday property on Rakino Island in 2014-5. As a long-time ‘off grid’ island bach owner, Perry brings a wealth of practical experience to bear, starting with a methodical and meticulous analysis of current and future power needs, which is steadily refined into a comprehensive proposal document and quotation, backed up with technical appendices and circuit diagrams.

He was also more than ready to consider subsequent change proposals, which enabled us to refine the final design and indeed to integrate some of the existing solar power equipment within the new installation, bringing an additional layer of flexibility.

We continue to be genuinely delighted with the result, which has transformed our enjoyment of the property and enables us to run a full size domestic fridge/freezer 24/7.....luxury indeed!

We’re 100% confident of Perry’s ongoing support and assistance to ensure we get the very best out of our investment".

Pacific Energy Solutions - Ergo Consulting / Watercare Services Ltd 2017 Case Study

Pacific Energy Solutions was engaged by Ergo Engineering Consultants to provide specialist engineering services for a number of renewable energy feasibility studies for Watercare Services Ltd. Watercare’s mission is to provide reliable, safe and efficient water and wastewater services. To help deliver this mission, Watercare implemented a new Energy Policy in 2016 aiming to become a leader in energy efficiency and to reduce its greenhouse gas emissions.

Watercare embarked on several initiatives to reduce its energy consumption and associated operating costs and to minimise the environmental impacts of its business activities. One of these initiatives was to explore the benefits of solar PV electricity generation and battery storage.

Pacific Energy Solutions Ltd led the high-level design and analysis of several potential systems across the Auckland region. This included:

  • Siting of large photovoltaic arrays (up to 2MW) and associated high-level design for connection back into the plant and the grid
  • Analysis of time of use readings to create detailed load profiles for each site
  • Detailed modelling and optimisation of each system based on load and generation profiles to achieve the best economic return (Nett Present Value after 25 years, IRR etc.). This modelling considered seasonal variations in both consumption and expected generation
  • An investigation into the potential for battery storage, development of a number of storage scenarios based on different criteria (e.g. maximum size based on PV output, sized for maximum self-consumption etc)

Systems were ranked based on the $/Watt system cost that provided a positive NPV after 25 years. From approximately 30 different scenarios, 4 systems were presented in a business case to the board for approval to go to market. An RFP was put together and the procurement process was initiated.

Pacific Energy Solutions’ analysis provided commercial rigour around the specification of system parameters including array size and orientation. “More” is not always better and our analysis ensured the “sweet spot” was found between system configuration and economic return.

We were able to provide the board with visibility around the business case enabling them to make a considered decision.


Pacific Energy Solutions - Off-Grid Rakino Island Case Study

Rob and Mandy Everall purchased their wonderful property on Rakino Island in 2014. Rakino Island lies in the Hauraki Gulf, just beyond Motutapu Island and is a three quarter hour ferry ride from the Auckland CBD. There is no reticulated power so an off-grid system is the only access to electricity.

Power Board showing inverter, pv control and switchingRob and Mandy’s home had an existing 12V DC system that was in a very poor state and our first task was to lend them batteries until we got a system up and running. Rob had a budget that he was working to so the next thing to do was a load analysis and assess exactly how they were intending to use their holiday home. We then came up with an agreed solution that fitted within Rob's budget and commenced putting the project together.

Basically, the system included a new 1200Wpeak roof-mounted photovoltaic array, a Studer inverter/charger that provided a 230V AC supply and also enabled charging of the batteries via a petrol generator, and the complete upgrade of the 12 V DC system to meet current standards.

All work was then independently inspected and a Certificate of Completion and a Record of Inspection were issued to give Rob and Many the assurance that all work was carried out to the latest regulations and electrical standards.
