Here’s what the locals had to say...

Greg advised us on what we needed to build our Solar system for a startoff with 3.5kw of panels. We went straight solar for a startoff for almost a year but I still liked the idea of a battery so I talked to Greg about it and he worked out a system where we would get maximum capacity by over sizing the 5 kw inverter with 6.5kw of panels so as soon as the sun hit the panels they would go to maximum output very quickly. The Solar Edge HD 5 kw inverter allows you to oversize the panels like this. All our panels also have optimisers on each one so each panel performs by itself. It looked good so we did it and added the Powerwall battery and upgraded our Solar system to full capacity of 6.5 Kw to get the most out of the battery. Greg was dead right and it worked like a dream !! The system with the Powerwall battery performs completely different from a straight solar system. Instead of going to the grid when solar is not enough it pulls it from the charge in the battery so we don't hardly touch the grid. During the summer we were basically off-grid with the battery taking the place of the grid with its battery charge. Then we found Contact Energy which gives 3 hours of free power from 9pm to midnight. Well that is just made for a battery system !! Our cycle goes -.> solar during the day runs the house and charges the battery -> solar ends so house is fully on battery -> 9pm free power kicks in, fully runs the house and takes the battery up to full charge by midnight -> house runs fully on battery until sun comes up and solar kicks in then the whole cycle starts again. Any excess solar gets exported to the grid and we get a credit on our electric bill for it. We are saving a fortune on electricity bills and I estimate the system will have paid for itself in 6 years with electricity savings. I even had the power co call me once to say they thought there was something wrong with my meter as we weren't using any electricity :) Calling Greg from Harrisons was the best thing we ever did !!

With thanks for your amazing service and assistance by the whole team at Harrisons with getting my solar system up and running. I am most grateful.

Sallie Greenwood

We are absolutely thrilled with the performance of the system. I can't speak too highly of the experience from your visit to the house to the final payment. Every step has been so smooth and well informed. Thank you both so much. I'm happy to sing your praises (and have already) to anyone who is considering solar.

Extremely satisfied with our Harrisons solar install. Julie and Greg were fantastic and answered all our questions, nothing was too much trouble. Their install team were really professional and efficient and did a great job. I honestly can't find fault with anything. Really appreciated the after install visit to make sure we got the most out of our system and knew how to use the app.

We are very pleased to have chosen Harrison’s Energy Solutions - Waikato to install our farm solar system. The service from start to finish was impressive, professional and personal. The installation team were well organised, clearly as the result of excellent communication from Greg and Julie. The post-installation visit was so important and as a result we have been able to monitor the system performance from day one. Our experience has changed the way we use our appliances and power consumption in general and consequently our monthly power account is a pleasure to receive. GO SOLAR.

We had Greg Foster install our solar system and it was done with ease and efficiency. However, the best thing has been Greg's after sales support. It's easy to sell something but it's the after sales input that really matters and here is where Greg has been fantastic - always available to answer quires and sorted out the initial teething problems without a fuss.

Bruce Clow

Waikato

We are happy with the (Ventilation) system, from the day it was installed all our windows including the frames have been dry. The first morning Lesley was looking and saying they were still wet, having a closer look it was the outside that was wet.

It is so quiet we don't hear the fan working, in our old house with a HRV System we could always hear when it was working. While I was not here when it was installed, Lesley said they were very good, saying where they were putting the vents, putting down plastic sheets to catch any debris, all in all very professional.
