Size: 3kw

Running for: about 4 weeks

Comments on the installation: "The installers (Harrisons - Solar Waikato Ltd.) were excellent: great communication; on time; clear explanation of the process of installation; polite; follow up to see we were happy. The only hick-up has been with the lines company that is to up-date the meter. Despite being informed immediately that the installation had been completed we were not contacted until just over a week ago that they would be installing in "a couple of weeks". Still do not have a firm day/time."

Comments on the system performance: "Not been going long enough to have had an effect on our last bill."

Jill, Christchurch City, Canterbury

Review Date: 22/03/2017

Size: 4.0kw inverter with 12 X 260w LG panels

Running for: was installed January 20th 2016 but only had input/output meter installed end February

Comments on the installation: "Our installers were great. We went with Harrisons Solar. They only took one full day. We had many delays from when first booked, but that was due to the weather. The contractor and Installers were wonderful to work with. It was the power company that i had issues with and ended up changing."

Comments on the system performance: "We have not received a full month bill as yet. There was a mix up with paperwork and the initial works order (for the input/output meter) went to the wrong power company. However this turn out to be in our favour as the company we were with would not let us run a day/night meter with our solar (the contractor had organized this to be installed, because of the paperwork mix up) and they wanted to charge a 'special' solar rate. We switched power companies and now have a day/night meter to make better advantage to the solar use, and we run a Hot Water Cylinder Timer. I do know that in our first week we had used 31% less power and that week had been mostly overcast. Our first bill, after the meter was installed, with our new company, was only for 16 days and at a rough work out I figure we would have saved paid $70 less if it had have been for a full month."

Advice: "check everything. get more than 1 quote. I got 5 and had (no obligation or cost) visits from two companies. after getting all quotes and after the visits then I settled on what system I felt was best for us, then went back to all companies to see what costings they would provide. don't be afraid to barter with the companies - I ended up with two companies trying to outdo each other in price, for similar quality. Also check that your current power company is not going to sting you with a 'special' solar pricing or hidden charges and that you can do what you wish with what meters you would prefer."

Size: 4.5 kW

Running for: 2.5 Months

Comments on the installation: "The installation was carried out by two very good installers, they did the job in good time and they were respectful of the property."

Comments on the system performance: "On days when we have had full sunshine the system has produced a lot of power. Considerable less on dull days but still good. We have saved around $100 per month on our power bill."

Advice: "The decision to install solar panels has been the right one, due to the area we live in they well continue to save us money."

Chris, Nelson/Tasman

Review Date: 29/09/2016

Size: 2.34 kW

Running for: 3 Months

Comments on the installation: "Installers turned up when they said they would. Carried out the total job in a couple of hours which was impressive."
Comments on the system performance: "As the days get longer we see an increase in production of course. During the winter months, believe we have saved at least 30% on our power bills, but as this is a new house with electric only heating, it could be an even higher saving."
Advice: "Due to low buy back rates in New Zealand, believe solar investment gives the best return only if you can use your appliances (e.g., dishwasher, washing machine, iron, vacuum cleaner, oven) during the hours of production - pre-programming on appliances makes this quite possible even if you're not at home during the day. Love the idea of reducing our carbon footprint, but think there should be more incentives for more people to do so."

Review Date: 27/09/2016

Size: 5.2 kW (we wanted to maximise the use of the garage roof space)

Running for: 2 Months

Comments on the installation: "Very painless installation, very respectful installers, took two days due to the weather. I would recommend that people seriously consider "What Power Crisis" (our installer)."

Comments on the system performance: "The system is performing as expected. We are saving money on our power bills. I think it has reduced them by a third. So far this month (September) we have generated an average of 11.1 kw each day."

Advice: "I would recommend considering going solar. I think picking the right supply plan is important. Our hot water is on a timer for daytime heating only, as is the deep freeze in the garage."

Charles, Waimakariri, Canterbury

Review Date: 04/09/2016

Size: 4 kW

Running for: 2 Months

Comments on the installation: "The Installation went smoothly. The Installers took only about a day to do the entire installation and answered all my questions during the process."

Comments on the system performance: "In spite of it being winter right now, we are quite pleased with the Solar System. We purchased the Power Genie along with the enlighten inverters and are happy with being able to use over 90% of what we generate. We have compared our last two months of generation and according to Contact Energy, we are saving at least 25% of our power bill. We hope to save even more during the Summer months."

Advice: "If you go solar, don't hesitate to go with the Solar Genie to maximize your use of what you generate. Why get paid only a fraction of what the power companies charge you for your own energy generation. Use as much as you can."

Size: 2.5 kW

Running for: 49 days (I keep a running log)

Comments on the installation: "Yes they respected our property and were very proficient, despite inclement weather."

Comments on the system performance: "Yes, the providers forecast have been spot on for June and July."

Advice: "Yes, we are saving about half the kWh on our previous power bills, because we're very conscious of switching off lights in unattended rooms, running laundry and dishwashers in separate times of day, etc despite being the lowest solar energy in mid-winter months."

Anne, Nelson/Tasman

Review Date: 27/07/2016

Size: 3.6 kW

Running for: 5 months

Comments on the installation: "We went through your company and asked the 3 companies locally to quote. We choose Solar Electric Technology in Richmond, because they were responsive, explained the pros and cons, visited promptly and had good knowledge, only took one day to install."

Comments on the system performance: "We have been delighted with our savings, we can use nearly all we make because we are home all day and can switch on and off to ensure efficiency."

Advice: "If people use Elios4you they can monitor and manage their use very effectively, reducing their power bills and having instant access to their own solar energy. Very positive impact."

Todd, Papamoa, Tauranga

Size: 3.5 kW

Comments on the installation: "Excellent, previous feedback given."

Comments on the system performance: "It is going really well. Over the past 3 months we have save $455.77 based on our average power bill over the preceding 12 months. Based on some calculations I have made, the system will be paid off from the savings, after 7 years."

Advice: "Definitely worth it if you don't let the savings get absorbed into the "big black hole" we are planning to pay the savings off our mortgage."

Comments on the installation: "The installers were very good and the install was pretty quick."

Comments on the system performance: "Because of the time of year it was installed it has not really produced to full capacity yet. It has saved us a small amount of money so far but is within our expectations."

Advice: "I definitely think it was worthwhile and I'm looking forward to battery technology improving and becoming affordable enough for energy storage to become feasible."

Alan, Central Otago, Otago

Review Date: 11/06/2016

Size: 5 kW

Running for: 2 months

Comments on the installation: "Installers impressive on PR, speed , tidyness and confident of their know how. Explained what they were doing and why, GREAT

Comments on the system performance: "So far our system has been running during the grimmest time of the year. Poor weather short days,all day fogs,hoare frost and snow. The system has been at least what we expected, goes well under fog cover! We are still learning to use it most efficiently but our power bills so far are about half even though one of the two is an estimate that is obviously a bit over."

Advice: "Ask me again in 12 months and I will really know. I expect it to do much better in summer to offset winter performance. We have an old "Centimeter" in our kitchen that tells us how many grid kW we are using, when the solar is running it tells us how much is being exported.....it takes a little playing to decide if we are importing or exporting. The panels certainly produce what they were designed to produce when everything is ideal weather wise."

Comments on the system performance: "It's too early to know yet."
