Size: 6kw
Running for: 3 months
Expected return on investment: 10%
Expected pay back period: 7 - 10
Comments on the installation: "Very professional with great communication"
Comments on the system performance: "Very happy with my system and its performance. I am able to compare with two similar sized installations within 10 km and we compare our daily solar harvest."
Advice: "At our age, we are not counting on recovering our investment through savings, however of the $15k was left on term deposit in the bank we would currently be getting around $40 / month in tax paid interest. However, having invested the $15k in solar our net savings are around $140 / month greatly helping eek out our meagre fixed income. We are heating all our hot water and charging the battery in our 2023 Mitsubishi Outlander PHEV every day. Our latest bill which includes $78.00 supply charge was $103. This includes the energy powering our car as we did not need any petrol."

Size: 5 Kw
Running for: 2 months
Expected return on investment: 3%
Expected pay back period: 25
Comments on the installation: "They were very good. No issues and did not take long"
Comments on the system performance: "It has exceeded expectation to date and produced more power than expected. However, once a full year is completed will be the real test. So far we have not used the grid at all so has saved us the whole power bill and has put back into the grid. Having a battery enables this to occur."
Advice: "Shop around and do the research. Don't necessarily go for the cheapest but the one that will meet your needsnot only now but make sure it is future proofed. As in have more capacity than you think you need at presant."

Size: 4.4
Running for: 3 months
Expected return on investment: 7 to 8%
Expected pay back period: 10 years
Comments on the installation: "The install went well, tidy neat job."
Comments on the system performance: "The system was installed in middle of winter when light levels are the least and power output the lowest. It has been a good learning curve working how to maximize usage of the power generated. In the first week of September we had a negative daily power bill where the income of the export exceeded the cost of power used so oower company paid us. Our daily power bill in Sept is averaging between 50 cent to 1 dollar a day so more than halved. This will only get better as day length increases."
Advice: "big learning curves for me were a) even after sunset it can generate power. b) solar levels not linked to temperature. So cold sunny day in Aug can be used to warm house using solar. c) don't install panels flat as will get dirty quickly and not self clean in rain, d) get analytics of production and use, so can maximise savings, e) get heat pump connected to wifi so can control remotely to maximise use when producing excess power, e) get hot water timer to control when it heats to use solar."
Review Date: 07/09/2024
Size: 6kW
Running for: 3 months
Expected return on investment: Too early to predict. Probably need a year or so to be accurate.
Expected pay back period: Too early to say. Ask me in 12 months.
Comments on the installation: "Install took 2 working days. Installers were good to deal with."
Comments on the system performance: "The system was first switched on in the middle of winter, and I was actually surprised at the amount of power we produced. We have definitely saved money. Our consumption has been reduced by half, and that is in the winter! We are looking forward to the longer summer days!"
Advice: "If you can afford it, just do it. Don't think to much about payback etc. We went into this looking at what the day to day savings would be, aiming to reduce our overheads. Be prepared to get the hose out, there is a lot of pine pollen (yellow) about at the moment."
Review Date: 28/08/2024
Size: 4kW

Comments on the installation: "installation went well, all done in 2 days"
Comments on the system performance: "considering it is running in winter for the first time, I'm very happy with the result. saving over $100 per month compared to the same time last year"
Advice: "If you can afford even a small system, it makes a big difference. Electricity keeps going up in price, Solar is a great solution, especially if your nearing retirement and won't be able to afford more price increases when you retire."

Expected pay back period: No idea
Comments on the installation: "Installers great job with a tricky install"
Comments on the system performance: "Producing more than anticipated for the time of year"
Advice: "Just do it. It's not just about ROI, a solar installation increases the value of your property, saves the planet and reduces your reliance on NZ's screwed electricity market."
Review Date: 05/08/2024
Size: 7400
Running for: 1 month
Expected return on investment: 109
Expected pay back period: 14
Comments on the installation: "The team were good, professional and courteous. Unfortunately there were delays in some of the equipment arriving meaning a gap of around 6 weeks from start to completion"
Comments on the system performance: "It is winter and early days so limited savings so far. Having said that, the battery means that we can significantly reduce peak use and charge from grid during off peak."
Advice: "It is well worth a look. Power will keep going up in cost so its good to insulate against that. We also had a local power outage and the EPS / battery back up kicked in so there was no disruption to kitchen appliances, internet, etc. so that part is also good to have."
Review Date: 17/07/2024
Size: 6.6kW
Running for: 7 weeks
Expected return on investment: Unsure as alterations to Meter Box only just done last week.
Expected pay back period: 10-15 Years
Comments on the installation: "Great installers, all done in under a day due to fine weather & 2 installers present."
Comments on the system performance: "No not so far. On sunny days only just achieving 50 per cent utilisation! Would have expected more & hopefully this will improve in summer! Delay in Genisis installing changes to meter box means nil savings so far from them."
Advice: "Still relatively expensive in NZ without any Govt Incentives. My daughter in Melbourne recently installed a 9.9kW system for less than AU$3300 with VIC State & National Incentives."
Review Date: 08/07/2024
Size: 8KW
Running for: Installation completed in early May
Expected return on investment: 100%
Expected pay back period: ~8 years
Comments on the installation: "Excellent. 1 day to install inverter & 14 solar panels Half a day to install the tesla battery."
Comments on the system performance: "Considering we are into winter it has performed as expected so far. When we have full sun shine days the battery is fully charged by early afternoon. We are still waiting for the new meter to be installed so we can get the full benefit of having solar. The power co we are currently with needed a bit of a rev up to action the new meter, why is it so difficult to speak to someone on the phone these days?"
Advice: "Initially I wasn't considering installing solar. As retirement loomed with associated concerns over soaring energy prices, it seemed a no brainer. A friend in Wanaka installed solar over 10 years ago & added more panels after some years. They enjoy total independence for most part & still have enough power to recharge the EV at the end of the day."

Size: 5kW battery
Running for: 4 months
Expected return on investment: Can't remember but believe I'm well ahead as EV charging all solar
Expected pay back period: Don't know, am looking for an easy to use spreadsheet to recalculate as I expect this wkill be greatly reduced.
Comments on the installation: "Very impressed with installation, everything from products to procedures and results."
Comments on the system performance: "I must be well ahead of ROI. All my EV charging is solar so I am saving a bundle there as well as well as running the house. At present my electricity bill is in credit so it will be interesting to check results after 12 months."
Advice: "Go for it. Get as many panels as will fit, a battery with at least 5kW, and if you have an EV, install an Evnex charger."
Review Date: 29/01/2024
Size: 4.5kw
Running for: 5 months
Expected return on investment: Unknown
Expected pay back period: 10-11 years depending on power consumption
Comments on the installation: "Excellent. Installers were respectful of our property and it took less than a day and then the electrical inspection on a later day only took a short period."
Comments on the system performance: "Quite happy with the performance of the system although it is producing less power than I would have thought for some of the very hot days we have had this summer. We haven't paid anything for power bills since the system was installed due to credits given for swapping power supplier, credits for power exported, and credit for the meter swap despite using our heat pump to cool the house on very hot days. We are in credit and hope this will continue so that the credit gets used up in the winter months when we use more power and the solar power system produces less power. The Goodwe inverter can feel very hot to the hand but we wanted a smaller inverter and one that did not have a noisy fan."
Advice: "Well worth it if you would like to contribute to a greener future and be more self-sufficient. We found both the NZ and AU solar quotes websites very useful for learning about panels, inverters etc so we were more knowledgeable when speaking with the 4 different companies we got quotes from and think this knowledge contributed to us getting a good price. We chose Lightforce."
Review Date: 21/01/2024
Size: 5kW i.e. 14 panels plusTesla Battery
Running for: 1 month
Expected return on investment: 100% Feel good factors
Expected pay back period: Don't care
Comments on the installation: "Installer worked efficiently but took a week to complete installation due to family commitments restricting him to half days and having to travel 1 hour to the site."
Comments on the system performance: "I chose a split array to give me longer generation time as opposed to peak generation yet am still getting peak of 4.5kW from a 5kW system and am generating from 0630 until 1930, as at 1 January, thus with battery use overnight I am 99% self sufficient. Last power bill showed I imported 3kWh at a cost of 46 cents however supply charges of $17.21 boosted the bill to $17.67 This is compared to $76 for the same period last year. Note: This was prior to the Export meter being installed so I confidently expect my next and subsequent bills to be in credit."
Advice: "Do independent research on components offered in quotes as some use near end of production components to keep costs down. Bottom line ...... don't skimp for the sake of a few dollars."
