Freenergy Solar Solutions - Zero Power Bill in Havelock North

We were thorough in researching whether PV solar power would be to our financial advantage and what was the best system for us. The results are better than we expected. Freenergy gave us a highly professional install, keeping us well-informed about the procedures. They worked with suppliers, lines and power companies to give us a turnkey operation. We installed a 5kw system, and the amount of power we’re generating for ourselves and the money we’re making from what we’re exporting back to the power company indicate our power bill this year should be virtually zero – around 11% return on investment.

Napier Intermediate Students enlist Freenergy Solar


The exciting thing about this project is it was driven by the students themselves. They researched solar energy, made some cost-saving calculations and looked at what some other countries are doing.

We installed a 70 panel 21kW onto Napier Intermediate School in the sweltering heat last week - how exciting for the 2017 year 7 students to return and see their project a reality. They will continue to study both the financial and environmental benefits of this system.

The project was so successful the BOT authorized the next phase and we were lucky enough to secure the contract through our product knowledge, quality equipment and our commitment to continue to work alongside the students in an educational role as they see their concept become reality.

Our solar modelling software calculates we will generate 32'000kw/h year, with a 19% return on assets the system will pay for itself in under 6 years.

A big thank you to The Principal, Miss Philips, all the students and the Board of Trustees for the drive, Dougan Larkworthy Team Architects for the architectural assistance and of course our team of quality installers who braved the heat on the roof.

If you are considering solar for your school, commercial premises or home, we will be happy to discuss your options and provide a detailed performance model and accurate ROI.


Freenergy Solar - Charging Dave's EV with Solar

Dave's home solar system is charging his EV during the day and you won't believe how much he is saving!

Freenergy Solar - Retrofitting Batteries

Optimising the home owner’s existing solar system for self-consumption

Retrofit an existing string system with an appropriately sized Enphase AC battery and Envoy gateway communication device to capture excess power generation for self-consumption

Radical reduction in grid-supplied power, minimal electricity bills "Self-Reliant" Target

Roger had an 8 panel, 2kw string inverter system and a hot water cylinder diverter (controller) installed by Freenergy in January 2015. Though Roger’s power bills were reduced after his initial installation he was finding his solar production during the day was more than he could use. Excess electricity was being exported to the grid during day (at 8c/kWh) and he was drawing electricity from the grid at night (at 33.33c/ kWh) – a sad deal no matter how you look at it.

Roger knew at the time of his PV install he wanted to be as self-reliant as possible, but the price point of the batteries on the market at the time meant it was not economical for Roger as a small residential system owner. Other batteries on the market were not appropriate for his residential system, installing a 5-8kw battery and paying upwards of RRP $9,000 NZD for another brand of battery was not financially viable - Roger would have been paying for excess battery capacity which his system simply would never use. The Enphase 1.2Kw battery was the perfect fit for Rogers 2kw system and at a much lower price point of RRP 2,500NZD.

In December of 2016 Roger contacted Freenergy, to design a system to optimise his self-consumption and reduce grid reliance through batteries that would power his house long after the sun went down.

Solar Energy After Dark
The Enphase AC Battery knows when the PV System is producing more power than what is being consumed and stores this energy ready to be used in the evening once the solar system is no longer producing power. Coming in modular 1.2kW plug and play blocks, the battery is much more suitable for smaller systems like Roger’s than the other oversized and complicated to install batteries on the market. The 1.2kW storage capacity the Enphase AC Battery is the perfect size for Roger's needs, but if he were to increase his system size, more batteries can be easily added to accommodate increased production.

Adaptable to Local Utilities Pricing Structures
Roger has also found the software of the Enphase AC Battery can be programmed to optimise it’s behaviour to suit the local utility’s requirements. With the recent Time-Of-Use pricing structures being implemented by New Zealand lines companies, the Enphase AC battery works seamlessly to discharge stored, free solar energy during the evening and also set up to charge from the grid during cheap off-peak times to help manage your high peak morning loads.

Retrofitting PV Systems with Enphase Batteries
“The great thing about Enphase products is that they are compatible with other brands, so it’s easy to upgrade an old string inverter system with Enphase monitoring and batteries”. Freenergy Solar Solutions are customer focused and spend time understanding each customer’s usage pattern, so they can design a solution that suits their customer’s individual needs. Aaron says he doesn’t favour one brand of inverter or battery over another and instead he simply chooses the best solution to suit his customer’s specific needs. Although Aaron does not sell Enphase exclusively, he says most of his residential installs use Enphase products, and many of his existing string customers are now upgrading to install an Enphase battery with advanced monitoring capabilities. “Expandability, future proofing - Enphase adds value to new and existing solar systems because their products are smart, versatile and allow for cost-effective expansion as technology evolves".
