The low fixed charge for homes is currently under review, and is likely to be abolished in the near future. The only thing that is really going to help is to sequester carbon by planting millions of trees. Why isn't the comments option a regular feature of your articles? When doing a google search to get the online form it is very easy to inadvertantly go thru an agent, and pay US$89 instead of US$14 for the same form. The array and battery are warrantied for 10 years, and the inverter should be replaced at 15 years. The batteries give me 18kW hrs of useable storage (50% DOD) and are miles cheaper than overpriced Testa Power walls) ) . 1. Installers then say your savings will increase every year as electricity prices rise. We think this is a good idea, as it allows the addition of generation capacity in the future (for example, if batteries were to be installed). Thanks for the feedback. * Shining a light on solar power - customers told to make sure it's worth it * Solar systems will put heat on prices, Vector boss says ... New Zealand Solar Systems, went into … What can be done to rectify this? Is there the possibility of taller buildings being put up in your area? Garmin's New Solar-Powered Watch Is a Beast In More Ways Than One Meanwhile, the bar graph just showed a single figure of 356kWh for the month, which I suspect is what your solar guy was referring to. I totally agree that reducing the cost of living when you are on a fixed income / pension is very important.

These systems can automatically turn your appliances on or off for the most efficient solar power usage. do the job properly. You might have a better argument if power generators paid grid distribution costs but they dont - its all consumers. Unfortunately Solar City had cancelled the install earlier as they had not yet standardized on vertical seam roofs! I would be hesitant if considering solar power in a domestic setting, owing to the patterns of use, but if the hot water heating is electric, perhaps it could work out. I take issue with your payback calculations. Don’t be put off by theory the practical reality is different. Before I really dive into the issue of energy storage, it is important to understand that there are two types of solar … Ditch the economists and their irrelevant theories. This report is not worth the paper it is written on. Over the previous 12 months our household usage averaged 31 Kwh per day (from the power bills), In the 8 months since installation we are averaging 20 Kwh/day. Hi There It also takes into account shading: http://solarview.niwa.co.nz/, You may also be interested in NIWA’s historical (1981-2000) mean annual sunshine hours for various locations around the country: My main reason for putting up the panels was guilt at my past carbon use (I have flown a lot), extreme anxiety about climate change and despairing of the NZ govt ever having the balls to give unpopular messages. Check this out - if your system is tied into a grid then if the grid goes off, then your system stops generating. A better option is using the power produced on your roof during the day. Though since 'deregulation' that (price increases) has been the only way to bet. I have acquired a second slow cooker so that I can cook and do things like the annual jam-making while the sun is out. Reducing your daily connection charge is awesome. Therefore, I would recommend roof maintenance be added to the factors to be considered.

Since this article was published, SEANZ has indicated they support our findings, acknowledging PV only “makes sense in the right environment” - see http://www.seanz.org.nz/News-Events/News/Consumer-NZ-Supports-Solar-PV, Kind regards, I notice that even Consumer can't bring itself to advise people not to fly. Here are a few helpful examples of what you can save with efficient solar power usage (assuming the NZ average export rate of 8 cents/kWh, as of October 2018): When done effectively with a thorough initial consultation, and optional built-in power management or battery storage, solar is a very effective way to save on lifetime power costs. Once the water is hot, the energy is wasted. hbspt.cta._relativeUrls=true;hbspt.cta.load(3417639, '589bffb9-b18f-4cec-a547-dd0c2d851690', {}); The team at World Solar are driven to get more Kiwi homes and businesses using the sun’s power to their advantage.

This information isn't on the website, and I was pretty disappointed to find out that they couldn't do the full install for the price on their website. Generally Paraparaumu Aerodrome weather station receives more annual sunshine hours than Wellington’s Kelburn station, so it’s odd that the BRANZ calculator is giving more kWh per year for Wellington. To maximise PV hot water you do need a small hot water controller like paladin (no I’m not affiliated in any way, but yes I do have installed). If you are thinking of solar then a change of mindset is also needed. You will pay more than three times as much to buy power from the grid as you’ll get for the power you sell.

Each company offers several brands of panels and inverters. Tesla Solar Roof cost. The cost of solar power systems has flat-lined in New Zealand after … The cost of scaffolding isn't cheap either, and can almost double the cost of the solar installation, meaning solar isn't a viable solution for a lot of kiwis. So a large system may be cheaper per watt generated, but it could take a long time to pay off the extra investment. I used a BNZ Term Deposit earning 3% interest to pay about $8500 for a 2.5kW solar array that I have estimated after two years production will pay for itself in about 5 years. In that time it has generated 19664kwh value $5033.12. It seemed self-evident to me that the pattern of use of the work building was far better suited to the pattern of use at home. They should also suggest power management systems that increase your savings over time.

The short answer yes, but it depends on what you value. Our roof is a 16 degree pitch, and I think they said west side, so more than 20% off north. But many solar users still use the peak capacity of the network". People measure the worth of solar panels against 3 main values, Saving money, … We have our major electricity consuming devices time clocked. If you are actually sucking more at peak times/dates it's the same again as a non solar installed site and you are paying the same rate (and proportion of distribution) costs that you are using. Even if I use all the power, pay only 6% interest, and power prices increase at 20%. I don't know the actual cost of that yet, but one electrician in Australia says "800 to 2,000". That could be because your home is occupied all day, you heat a spa pool, run a swimming pool pump, or have an electric car charging. Same for hydrogen fuel cells in cars. However, you can expect a maintenance-free run over this period. With an optional battery as part of your solar system, your nighttime energy consumption is taken into account for the best possible savings.

This factored in the pool that was being installed and would allow for more panels to power the pool pump and potential water heating. Are solar panels worth installing in New Zealand? Hi. This system generates between approx 15kWh (winter) and peaking at 50kWh (summer). Currently pays 26¢/kWh, uses 7880 kWh per year. And the dominant solar PV technologies currently have some harmful environmental effects related to their production and end-of-life disposal.

Using timers to delay and stagger appliances could be one part of the puzzle. Solar panel installation prices are measured per watt. Just think NZ needs to wait a bit before charging off down the route of a heavy investment in battery technology, as the products are evolving so fast we may end up in a technological cul-de-sac. String inverters only work as well as the worst-performing panel – if one panel is shaded, it brings down the power generation of the whole array. Our outlay was 12 panels and the cost was around $12 000 for the panels and another $1000 for incidental expenses including a new meter and electricians and inspections. Even if Tiwai Point closes, electricity prices will increase. You might see or hear the term “tier one” in solar panel sales pitches. If you are generating solar and not storing any of it, that 100% coal fired power is still used because it's primarily at peak load in the morning and evening when solar production is at a minimum.
