Grid backup and Off-Grid
How Does Solar Power WorksCollecting solar power with solar panels: Solar photovoltaic panels (PV panels for short), convert sunlight into DC electricity. Solar Group is a proud partner of Canadian Solar. Our Solar panels are guaranteed to deliver energy for 25 years, and you can take that to the bank. Converting solar power: The solar inverter converts DC solar power to AC power for your home or business. Solar Group offers the New Zealand made Enasolar Inverters, the best and most robust inverters for new Zealand conditions, with free Wi-fi power monitoring already built in! Track your generation in near real time.Distributing solar power: Your home always has power, because you are connected to the grid. However, when using more power than the solar panels can produce, such as during night time, you will buy the power from the grid. And when using less power than the solar panels produce, such as the middle of the day, you will sell power to the grid. The net result is that you use less electricity from the grid and may also build up some credit from power sold back to the grid.

Solar PV FAQ
1. What does a solar electricity system cost for an average sized home?
Affordable solar electric power can be yours for as little as $7,500 installed for our introductory system.
2. How do I choose which solar power system is best for me?
Request your free design from our solar consultants. Make sure you have a recent copy of your power bill handy. We will work with you to match your energy needs, budget and available roof area to a system that is perfect for you.
3. What are the warranties or what is the system life?
Your solar PV system consists of both solar panels and a solar inverter. The solar panels are guaranteed to produce not less than 80% power after 25 years of life than on the first day installed, and are warranted against mechanical failure for ten years. The solar inverter has a standard 5 year warranty that may be extended to 10 years.
4. Will you need to do a site visit?
If you have clear building plans or a good satellite image of your current house, we are able to start the design and estimation process from here, and provide you with an estimate at your convenience. If you accept the design, then we will need to conduct a site visit to assure that all of the site details are in order, and make any minor design alterations that are required
5. Do solar power systems require council consent?
As of now, solar Photovoltaic systems do not require building consent. However, to export energy to the grid, an application will need to be made to your lines company, which we can do on your behalf if you so wish.
6. Do solar power systems require maintenance?
Photovoltaic system require very little maintenance, having few moving parts. A simple maintainence check such as checking the cables are secure, connections are tight, and that the modules are clean will most often suffice.
7. Do you provide solar hot water systems or heat pumps?
Yes, we offer the full compliment of renewable heating and solar generation products.
8. Who buys back electricity and are there any guarantees that they will continue to do so?
There is no governing policy in NZ regulating the ´buy back price´ of electricity from micro-generators – each electricity retailer sets their own buy back policy. When comparing retailers, as well as looking at their buy back rates, you should also consider their retail rates for your area. Ultimately the best retailer for you will depend on the amount of solar power produced by your system which you can use internally within your home, and how much you are likely to be exporting back to the retailer. Below are the current buy back rates from retailers offering to buy back your generated energy: RETAILER SYSTEM SIZE EXPORT POWER RATE Contact Up to 10kW 17.285c / Unit, + GST Contact More than 10kW 7.0c / Unit, + GST Genesis – 4 to 7c / Unit (North Island Only) Mercury Energy – 1:1, surplus at 3.5c / Unit (Auckland) Meridian Up to 150 units per month 25c and 10c thereafter Trust Power Up to 10kW 7.0c / Unit + GST
9. Are there any Government subsidies?
There are currently no government subsidies at the moment for Solar Photovoltaic in New Zealand. We suggest you compare between major electricity retailers to get the best rate for you.
10. Does the weight of the solar panels put a lot of pressure on the roof?
Your roof is already built to hold the weight of a person walking along it. Our solar panels weigh much less than a person, about 19kg each, and this weight is spread evenly over many points, so the load on you roof will be minimal.
11. Where are the solar panels and inverters made?
We source our solar panels from Canadian Solar, the world 5th largest solar PV supplier and manufacturer. Our inverters are proudly made in New Zealand by Enasolar.
12. Does a grid connect solar power system use batteries?
No, grid connected system does not require batteries. If you would like to use batteries as an emergency backup, these can be purchased separately.A different inverter may also be required.
13. Completely off the grid, can I do that?
You can go of grid, but bear in mind that off grid systems, unlike grid connected systems, must relay on battery backup and generator backup to give you energy security. A typical off-grid system might be double the cost of a grid connected system, so it is best to only consider off-grid if you are already in a remote location and rely on a diesel generator.
14. Will my roof orientation and roof slope affect my solar electricity system performance?
The most ideal orientation will face due-north at latitude of the site; however any system pitched between 20 and 40 will perform well. East facing or West facing systems will also perform reasonably well, up to 85% of a north facing system in Auckland. East and west facing systems gain more energy during the morning or evening respectively, typically right when that energy is most needed in a typical household.
15. How long does it take to get a solar power system?
The full process from acceptance of the quote, to installation, to powering on and enjoying free power can take up to 50 working days, because of the work and verification that must be done with the lines company.
16. What is the difference between monocrystalline, multicrystalline (or polycrystalline) and thin film solar modules?
Monocrystalline, multicrystalline (or polycrystalline) and thin film (amorphous) solar modules are each manufactured in a different way, and have different structure. Monocrystaline cells are made from a single crystal, are most expensive to produce and are most efficient. Polycrystaline cells are made from many crystals, can be produced simply, but are not as efficient because of the mis-matching crystal structure, . Thin film panels are manufactured with random non-crystal structure, making them least efficient, however they have a higher temperature threshold and can have other special uses, such as flexible solar panels.
17. What is the difference between kW and kWh?
kW is a measure of power produced by the solar panel in an instant during operation, whereas kWh is a measure for the energy units produced.
18. Can I still use all of my electrical appliances?
Yes, you can use all of your existing electrical appliances. However, while you are considering investing in solar, why not also consider upgrading your appliances to energy efficient ones?
19. What if there is a grid power outage?
If there is a grid power outage, your inverter will automatically stop producing power for safety reasons. This automatic protection is called anti-islanding protection. You will need to wait until grid power is restored before you inverter will automatically resume converting energy or exporting power to the grid.
20. What is grid connected solar power?
Grid connected solar power is solar power that also depends on the grid to import additional electricity when needed.
