Solar security cameras work through an NZ winter, but only when the panel gets direct sun and the camera isn’t triggered all day. June sunlight is under a third of December’s in Auckland and under a fifth in Dunedin and Invercargill, so where you put the panel matters more than which brand you buy.
This guide is for lifestyle-block owners, bach owners, renters and anyone watching a gate, shed or driveway far from a power point. It uses NIWA’s solar radiation data to show what a small camera panel can collect in each main centre, and it covers the cameras sold in NZ and what to do where there is no Wi-Fi. For the wider choice between wired, battery and cloud systems, see our home security camera guide.
Key takeaways
- On an average June day a flat surface gets 1.0 to 1.8 kWh of solar energy per square metre across NZ’s main centres, against 5.5 to 6.3 in December (NIWA).
- A 2.5 W panel facing north covers a typical battery camera’s winter use several times over, even in Christchurch; shade or a south-facing wall can leave it short.
- Busy spots drain batteries: 100 clips a day uses nearly four times the energy of 20.
- Solar cameras still need Wi-Fi at the mounting spot unless you choose a 4G model, and lithium batteries generally won’t charge below 0 °C.
- NZ options include Tapo’s C610 and C660 kits (from about $229) and eufy’s SoloCam S220 and S340 ($299.95 and $499.95 RRP).

How much winter sun do solar cameras get in NZ?
NIWA’s climate records show how sharply solar energy falls in winter. The figures below are mean daily global solar radiation on a flat surface, converted to kWh per square metre, which is the same as peak sun hours.
| City | June (kWh/m² a day) | December (kWh/m² a day) | Annual sunshine hours (1971–2000) |
|---|---|---|---|
| Auckland | 1.8 | 6.3 | 2,060 |
| Wellington | 1.4 | 6.3 | 2,065 |
| Christchurch | 1.3 | 6.2 | 2,100 |
| Dunedin | 1.0 | 5.5 | 1,585 |
| Invercargill | 1.0 | 5.9 | 1,614 |
The low sun angle is the other half of the problem. At midwinter the noon sun sits only about 30 degrees above the horizon in Auckland and about 20 degrees in Dunedin and Invercargill, so trees, fences, neighbouring houses and your own roofline shade a panel for far longer than they do in summer. A spot that is sunny in March can be in shadow all day in June.
Will a solar camera keep up in winter?
A solar powered security camera uses very little power while it waits, and most of its energy goes on recording clips and live view. That means the question is less about latitude and more about how often the camera wakes up and how much sun the panel really sees. The calculator compares the two for an average June day.
Solar camera winter check
Compares what a small solar panel can collect on an average June day in your city with what a battery camera uses, so you can see whether it will keep up through winter.
Sun data: NIWA mean daily global solar radiation for June and December on a flat surface (Auckland 1.8 and 6.3 kWh/m², Invercargill 1.0 and 5.9). Assumes 50% of the panel’s rated output reaches the battery after angle, cable, charging and temperature losses; 2 W while recording or streaming and 0.03 Wh a day on standby, roughly in line with Tapo’s C425 claim of 300 days from a 10,000 mAh battery at 230 seconds a day; and a 37 Wh (10,000 mAh) battery. Lithium batteries generally won’t charge below 0 °C, so frosty mornings cut winter charging further. Treat results as a rough guide.
With the default settings, a 2.5 W panel facing north in Christchurch collects about 1.6 Wh on an average June day, while a camera recording 20 twenty-second clips and two minutes of live view uses about 0.32 Wh. That is roughly five times what it needs. Move the same camera under a south-facing eave in Invercargill, pointed at a road that triggers it 100 times a day, and the panel collects about 0.3 Wh against 1.2 Wh used, so a full 10,000 mAh battery would be flat in about six weeks.
Getting the most from a camera solar panel
- Face the panel north and tilt it steeply for winter, roughly your latitude plus 10 to 15 degrees, or about 50 to 60 degrees in most of NZ.
- Keep it clear of shade between about 10 am and 2 pm in June, when most winter energy arrives.
- Use the panel’s extension cable so the camera can watch the right spot while the panel sits in the sun.
- Cut false triggers with activity zones and lower sensitivity, and shorten the clip length.
- Wipe the panel every few months; dust, bird droppings and salt film all cut output.
Solar security cameras worth considering in NZ
The best solar camera for an NZ property depends on your budget, whether you want a hub that keeps footage in the house, and how much detail you need.
| Model | Panel | Resolution | Notes | NZ price |
|---|---|---|---|---|
| Tapo C610 KIT | Included | 2K 3MP | Pan/tilt | From about $229 |
| Tapo C660 KIT | Tapo A201, charges at up to 2.5 W | 4K 8MP | Pan/tilt, 10,000 mAh battery, dual-band Wi-Fi, IP65 | From about $240 |
| Tapo C615F KIT | Included | 2K | Pan/tilt with floodlight | From about $289 |
| Tapo C425 | Optional A202 panel | 2K 4MP | 10,000 mAh battery, IP66 | From about $172 plus panel |
| eufy SoloCam S220 | Built in | 2K | No hub needed | $299.95 RRP |
| eufy SoloCam S340 | Removable 2.2 W panel | 3K wide plus 2K telephoto | Pan/tilt, 8 GB built-in storage | $499.95 RRP |
| eufyCam 3 (S330), two-pack | Built in | 4K | Records to a HomeBase 3 | $1,329.95 RRP |
Tapo solar cameras
For the budget end, the Tapo solar kits are the obvious start, and the C660 KIT’s 4K sensor and dual-band Wi-Fi make it good value at about $240. The C425 battery camera can also take Tapo’s A202 panel if you want a fixed view rather than pan/tilt.
eufy solar cameras
eufy’s solar cameras cost more but need no subscription and can feed a HomeBase that keeps footage inside the house. Eufy says the eufyCam 3 needs about two hours of direct sun a day to stay topped up, which is a useful benchmark for checking a mounting spot in June. Eufy also sells a separate Smart Solar Panel ($129) for compatible cameras.
Arlo and solar
Arlo sells a solar panel charger for cameras such as the Pro 6th Gen, but its cameras need an Arlo Secure plan to save recordings.
Solar cameras with no Wi-Fi: 4G options
A solar camera removes the power cable, not the need for a network. Most still connect over 2.4 GHz Wi-Fi, which rarely reaches a gate 200 metres down a lifestyle-block driveway. There are two fixes.
- Bring Wi-Fi to the camera. An outdoor Wi-Fi extender or a point-to-point wireless link can carry your home network to a shed or gate, and then any Wi-Fi solar camera works.
- Use a 4G camera. Models with a SIM slot send clips over the mobile network instead, such as Arlo’s Go 2 ($489) or eufy’s 4G LTE Cam S330 ($799.95). Check coverage from your network at the exact spot, budget for a data plan, and use activity zones so a windblown hedge doesn’t eat your data.
Placement rules for 4G and Wi-Fi cameras are the same as any other outdoor camera; our outdoor security camera guide covers height, angle and weatherproofing.
Choosing a solar panel for a security camera
Camera panels are small, typically 2 to 3 W, and the camera’s own charging circuit sets a ceiling on how fast it charges. The C660 KIT’s A201 panel, for example, charges at up to 2.5 W. A larger panel won’t raise that ceiling, but it reaches it more often on dull winter days, which is exactly when you need it. Stick to the maker’s panel or one it lists as compatible, so the plug, voltage and charging limits match.
If you need more than a camera, such as a PoE camera plus a 4G router at a remote gate, you are into a proper 12 V off-grid system with a bigger panel, a charge controller and a deep-cycle battery. Our solar panel and battery calculator sizes that kind of setup for NZ conditions.
Common mistakes with solar cameras
- Mounting the panel where the camera goes. The best camera spot is often a shaded south wall. Run the panel’s cable to a sunny spot instead.
- Checking the sun in summer. Stand at the spot at midday in June, or picture a sun about 20 to 30 degrees above the northern horizon.
- Leaving sensitivity on maximum. A camera facing trees or a road can trigger hundreds of times a day.
- Expecting 24/7 recording. Most solar battery cameras record motion clips to save power.
- Forgetting the frost. Lithium batteries generally won’t accept charge below 0 °C, so in Central Otago or Southland a frosty morning’s sun can go to waste.
Our take
- Yes, solar cameras work in NZ winters, including Southland, provided the panel faces north with a clear view of the low midday sun and the camera isn’t triggered by traffic or trees.
- Best value: the Tapo C660 KIT for 4K pan/tilt coverage at about $240, or the C610 KIT if 2K is enough.
- No subscription and local storage: eufy’s SoloCam S340, or eufyCam 3 kits if you want a HomeBase.
- No Wi-Fi at the spot: extend your network first, or choose a 4G camera and budget for data.
Prices were checked in September 2026 and change often; “from” prices are the lowest NZ retail listings we found and RRPs are from brand stores. The calculator uses long-term NIWA averages and rough efficiency assumptions, so real results vary with weather and site. Nicegear is independent, sells nothing and has no commercial relationship with any brand mentioned.

FAQs
Do solar security cameras work in winter in NZ?
Yes, if the panel gets direct midday sun. June brings only a sixth to a third of December’s solar energy, so a north-facing, unshaded panel keeps up comfortably, while a shaded one or a camera triggered all day can run flat.
How much sun does a solar security camera need?
It depends on how busy the camera is, but eufy’s benchmark for its eufyCam 3 is about two hours of direct sun a day. A quiet camera needs less; one facing a busy road needs more.
Do solar cameras work without Wi-Fi?
Most don’t, because they send video over your Wi-Fi even though they take power from the sun. For sites with no Wi-Fi, use a 4G camera such as the Arlo Go 2, or extend your network with an outdoor access point.
What size solar panel do I need for a security camera?
The maker’s own 2 to 3 W panel is enough for most battery cameras if it faces north without shade. A larger panel helps most on dull winter days, but it can’t charge faster than the camera’s own charging limit.
Can solar security cameras record 24/7?
Most solar battery cameras record motion clips to save power. Some kits advertise continuous recording, but that uses far more energy, so check the specifications and expect it to struggle in a southern winter.
Does frost affect solar cameras?
Yes. Lithium batteries generally won’t accept charge below 0 °C, so on frosty mornings the camera may not charge until it warms up, which reduces winter charging in inland and southern areas.
Where should I mount a solar panel for a camera in NZ?
Face it north, tilt it steeply for winter (about 50 to 60 degrees), and keep it clear of shade from mid-morning to mid-afternoon in June. Use the extension cable rather than mounting the panel in the camera’s shadow.
