FAQs
Sol•Flare prioritises using all available Solar to heat your hot water. If by 5pm your cylinder is not fully heated to 60 °C because of weather conditons, then it will automatically mains boost it to 60 °C to ensure you have a full cylinder of hot water for the evening.
This varies a lot based on your cylinder size and how tepid your water is. For larger cylinders it can take between 4 and 6 hours to fully heat your cylinder.
Sol•Flare is primarily designed to heat a single hot water cylinder but does have the fuctionality to heat a second cylinder with additional installation requirements.
Yes, however you should not need to do this unless your household hot water consumption patterns drastically changes on a particular day.
For households using large amounts of hot water in the evening, Sol•Flare is alsso able to be scheduled to utilise low tariff rates overnight to mains boost your hot water to ensure you have sufficient hot water for morning showers.
Yes, it's fully configurable. To maximise use of Solar, Sol•Flare will heat your cylinder up to your Cylinder's maximum rated temperature which is often 70 ｰC.
Sol•Flare is a dedicated solar electric hot water solution designed specifcally to cost effectively and optimally heat water using Solar pane power.
No. Mains power is not needed to heat solely from Solar and Sol•Flare will work completely fine without mains power. However, for comfort of guaranteed hot water on poor weather days, mains power will be required to provide a boost.
The system compliments the seasonal performance of wetback cylinders very well. Many Southlanders use a combination of wetback heating in winter and Sol•Flare heating outside of winter - they are a perfect pairing for the deep south to remove all of your water heating power bills.
Sol•Flare takes every bit of energy produced by Solar Panels and channels it to heating your hot water. All hot water cylinders heat in a binary manner - generally consuming 3kWatts of power either on or off. However, Sol•Flare's magic is that it is able to heat cylinders in a non-binary way - by utilising every small bit of power prouced from Solar Panels continuosly over the whole day to heat your hot water. This makes a very efficient way to heat your hot water with a great benefit of extending the life of your heating elemetn and thermostat !
This is difficult to answer, and depends on many factors, including costs and payback periods. What we do know, is that Hot Water represents a consistent daily power drain on households (this is often referred to as a consistent base electriacl load), and for this reason it makes sense to have a dedicated Solar Electric Hot Water system to supply this portion of your electrical load which does not fluctuate much day to day. This approach is referred to as maximising your self-consumption of solar, and is globally accepted best practice.
Hot water cylinders generally only heat to 60 °C by mains power because there is additional mains power waste to heat it hotter than 60 °C . However Sol•Flare is able to water to a higher temperature like 70 °C with the solar power, which effectively increases the storage capacity of your HWC by 20% - expanding the size of your hot water cylinder without changing your cylinder. We all love longer showers !!
Sol•Flare utilises the existing mains cable that is wired to your hot water cylinder, together with an aditional temperature sensor. Its that easy.
All hot water cylinders rely on the principle that hot water rises. Cold water enters at the bottom of the cylinder and is heated by the heating element also located at the bottom of the cylinder, and then rises to the top of the cylinder once heated, and leaves the cylinder to supply the house from the top of the cylinder. The natural layering of the hot water inside the cylinder means that almost a full cylinder of hot water is able to be supplied to the household with very little blending of cold water from the bottom.
Sol•Flare will only manage power to your hot water cylinder. It will prioritise solar power for heating and only use mains power when necessary to guarantee hot water.
Yes, Sol•Flare is compatible with all hot water cylinders, regardless of type, volume, brand or age. It works well with low-pressure cylinders, meduim pressure cylinders, mains pressure or high pressure cylinders. We have even fitted Sol•Flare to cylinders from the 1950's.
Yes, Sol•Flare will utilise up to 10 solar panels and heat water to 85ｰC for equipment sterilisation. It will manage mains power heating during the night to guarantee hot water availabilty for morning milkings.
The OneEnergy.nz system utilises your existing hot water cylinder element with no need to replace or modify anything. No plumbing is required. The existing element will only be replaced if it becomes faulty or if you would like a larger capacity element for greater performance.
Yes, NZ electrical safety regulations require a dedicated DC isolator switch for the solar PV array, along with an AC isolator for the mains power connection, all of which are managed by our installer.
Yes, Sol•Flare includes connectivity features, allowing for system monitoring, performance data analysis, and potentially remote control via a companion app connected to your home internet. A WiFi connection is advisable but not essential.
Yes, Sol•Flare can be confgured to utilise preferred schedules to ensure any mains boosting occurs during cheaper, off-peak electricity periods. This will provide you with additional savings over and above the savings from Solar power.
Yes, you will still have piping hot water. If solar generation is low because of weather conditons, the Sol•Flare will seamlessly boost your hot water from mains power. Solar is always prioritised so that you minimise use of mains power..
Very well. Solar panels actually perform better the colder they become, and because the panels are rated to -25 °C, you will still get good performance on those cold clear frosty Otago mornings.
Hot Water Cylinders are usually set to heat to 60 ｰC so that you do not consume excess amounts of mains power. Sol•Flare will use any extra Solar energy to keep heating the water up to your cylinder's maximum temperature rating (usually 70 ｰC) and then automatically stop drawing power.
Aboslutely. By heating your hot water to 70 ｰC rather than 60 ｰC this provides you with about 20% more tempered hot water. Your plumber will have installed a 50 ｰC tempering valve on your hot water cylinder outlet, so by heating the cylinder hotter means your 50 ｰC hot water circulated around the house will last 20% longer. We all love longer showers !!
Yes, Sol•Flare constantly monitors the water temperature just above the heating element. When target temperature is reached, Sol•Flare will stop the heating. All cylinders also have a mechanical thermostat fitted which will also stop the heating when the maximum operating thermostat of the hot water cylinder is reached. So your cylinder will have now have an additonal safety layer to prevent any risk of water overheating !
NZ Building Code (G12) requires all hot water cylinders to heat to a minimum of 60 degrees weekly to avoid legionella. Sol彦lare enforces Legionella protection by making sure your cylinder is heated to 60 ｰC daily, and if Solar has not taken your cylinder to 60 ｰC then Sol•Flare will mains boost it to 60 ｰC to ensure there is no legionella risk.
Sol•Flare includes many safety features to prevent both thermal and electrical hazards. These include water over-temperature cut-off and hardware over temperature cut-off. The German designed and manufactured Sol•Flare conforms to the high European Safety Standards. Electrical surge and over voltage protection is also incorporated, as is short circuit protection, making Sol•Flare a very safe product. The Sol•Flare has been certified locally to NZ Standards.
Yes, Sol•Flare works on any standard 1kW to 3.6kW Water Heating element and uses pulsed DC current to simulate AC current. Sol•Flare's approach prolongs the life of your heating element.
Sol•Flare enforces Legionella protection by making sure your cylinder is heated to 60 ｰC daily, and if Solar has not taken your cylinder to 60 ｰC then Sol•Flare will mains boost it to 60 ｰC to ensure there is no legionella risk. This is configured by setting Legionella paramters to "0" in the configuration, and is set by defaul on Sol•Flare. We strongly suggest this setting is not changed.
PV panels generally degrade less than 0.5% per year. This means that after 25 years, the panels are producing no less than 85% of their initial energy output. We use superior Tier 1 panels that have a 30 year 87% Manufacturers Power Output Warranty.
Yes, the panels can be installed on a flat roof using a specialised anodised aluminium adjustable tilting mounting system. This system tilts the panels to the optimal angle for solar exposure while ensuring secure attachment and roof integrity.
Yes, the system can handle panels on multiple orientations like East and West. Sol•Flare uses advanced power management technology to maximise the energy harvest and to guarantee hot water.
Yes, however we generally recommend against it, unless you have roof space constraints. Fewer panels will means a lower percentage of your hot water heating will be solar-powered.
Yes, the system is scalable. Up to 10 solar panels (4.5kW) may be fitted if your household has substantial hot water consumption or a larger tank than normal.
Yes, Sol•Flare operates as an independent PV system and will not interfere with an existing mains connected PV system. The Sol•Flare will take the hot water cylinder's electrical load off your exisiting system, freeing up solar power for the rest of your house and prolonging it's life to save you money.
If your cylinder requires replacement then standard costs of replacing a hot water cylinder will apply. If you need a replacement cylinder please talk to us, as we have NZ wide relationships with cylinder manufacturers to get you great pricing.
No, you will not need to replace your hot water cylinder. Sol•Flare will operate with all existing hot water cylinders - using them as a giant battery.
No, the system uses roof-specific mounting kits that allow for secure, weathertight installation on almost any roof type, including corrugated iron, decramastic, long-run, concrete or ceramic tile, and flat roofs.
If the old thermal collectors still work, they can stay, but typically they will be replaced as there will be little to no need for them. The existing hot water cylinder can be reused, and the new Solar panels and Sol•Flare would be installed as an upgrade, converting your old system to the latest solar electric hot water technology.
Absolutely. You can adopt a much larger solar system at a later stage and Sol•Flare will take the hot water cylinder electrical load off your new inverter and batteries. This will prolong the life of your new inverter, and reduce the battery size you will require because Sol•Flare is already using the hot water cylinder as a giant battery.
The maximum distance between the panels and Sol•Flare is limited by voltage drop, which generally allows for long runs up to 50 metres. Sol•Flare is installed beside the hot water cylinder, which fits for 99% of houses. Typical installations will place the solar panels less than 15 metres from the hot water cylinder. There is no minimum distance.
Yes, we will issue an electrical certificate of compliance after the installation to certify that the installation was done according to relevant NZ electrical standards and safety codes.
The mounting system is engineered and certified to meet the wind load requirements governed under New Zealand building codes, ensuring the panels are securely and reliably secured.
Solar panels are secured using certified black anodised aluminium racking and mounting brackets screwed into the purlins of the roof structure. This creates a robust, structurally compliant anchor.
Our building code compliant and certfied mounting system requires roofing screws to be fastened through the roofing material for the mounting brackets. These mounting brackets have a rubber foot that compresses to guarantee waterproofing once fitted. A cable penetration will be made and fitted with a UV approved flashing that is meticulously installed, sealed and waterproofed to maintain the long-term weatherproofing of your roof.
Yes, the mounting system is highly reliable, certified, and compliant with all relevant New Zealand building codes, including NZS 1170.2 (Wind Loads) for structural integrity and durability. For high wind areas, additional mounting brackets may be fitted for wind loading.
Yes, all solar panels are compliant to NZ standards and are highly reliable, durable, and suitable for withstanding harsh NZ weather conditons. This includes high UV exposure, rain and hail impact, and cold temperature and frost extremes. We supply Tier 1 solar panels backed with a manufacturer's warranty.
Many NZ banks offer "Green Loans" or interest-free home loan top-ups for eligible energy-efficient upgrades. You apply directly to your bank utilising our quote, which will provide your Bank with comfort that installation is completed by a reputable installation business.
No, this is not a DIY installation. Solar and mains require a certified electrician to ensure safety, compliance, and warranty validity. If you prefer to use your local electrician then please ask them to contact us directly so that we can enable them to perform your installation.
No, building consent is not generally required and responsibility lies with the home owner to ensure they have local consent if this is required.
Very little. The panels are mostly self-cleaning with rainfall, and no servicing of Sol•Flare is required. Annual gentle washing of the solar panels will be benficial to slightly improve performance. Regular visual checking for debris is recommended.
Absolutely not. When the electrician fits your new hot water cylinder, they will use the same wiring to wire the new hot water cylinder. No impact to your cost of replacement at all. If you need a replacement cylinder please talk to us, as we have NZ wide relationships with cylinder manufacturers to get you great pricing.
If a fault occurs, you should contact OneEnergy.nz immediately for technical support and troubleshooting. Please refer to our Support page for technical support Q&A.
