Most construction sites have no dependable power at the spot where a camera belongs. The best view is usually from a pole, a rooftop, or a neighbouring building, and getting an electrician to run a circuit there costs a few hundred dollars before you deal with weatherproofing the connection.
Solar removes that job. It also removes the reason people stop using time-lapse cameras: having to climb back up.
When solar is the right choice
Solar makes sense when the camera position has no reliable AC, when the project runs longer than 6 months, or when the mount is somewhere you'd rather not revisit.
It also lets you move the camera to the next site without planning power again. Several customers buy solar panels for indoor cameras purely so the kit redeploys outdoors later.
AC power still wins indoors, in warehouses, and anywhere a weatherproof outlet already sits within reach of the camera. For those positions an AC kit is the simpler choice.
Battery-only works for short jobs. At a 15-minute interval a DataLens battery runs about 27 days. Recharging means taking the whole unit down and bringing it back up, so on a year-long project that's a dozen trips up the pole.
Solar time-lapse and solar security cameras are different equipment
A security camera streams video and needs constant power. That's why solar security systems arrive on trailers with large panels and deep-cycle batteries.
A time-lapse camera wakes up, takes one photo, uploads it, and powers down. A panel roughly 1 foot square handles that load.
If you want to check the site during the day, most CamDo systems have on-demand live view: a burst of images uploaded at about 1 frame per second, on request. That covers the "what's happening right now" question at a fraction of the power and data cost of streaming.
Top picks by use case
Simplest cellular setup: DataLens. 4K, cellular modem and SIM built in, rated to -20°C. Battery state is visible in CloudX, so you can see the charge level remotely instead of guessing from whether images are still arriving. Setup is a SIM card, a power switch, and the rest done in the cloud.
Best image quality: SolarUpwith the Sony RX0. 15 MP with a better sensor and better low light than the 27 MP GoPro. It's modular, so there are more steps: firmware, SD card, USB modem, external battery.
Matching an existing GoPro kit: SolarUp with the HERO13. Check the temperature rating against your site. The GoPro's own limit is the constraint on cold jobs, not the solar system.
Indoor or powered positions: either camera without the panel, using AC or battery.
What it actually costs
The solar version of a camera costs a few hundred dollars more than the battery or AC version. That's roughly what you'd pay an electrician to bring power to the same position, and you only pay it once.
Budget for the rest of it:
- Cloud subscription per camera, per month
- Cellular data (included in the DataLens subscription; bring your own SIM on SolarUp)
- Mounting hardware, which you supply
- Any relocation partway through the project
Winter, clouds, and snow
This is the question we get on nearly every call. The useful figures are battery reserve without any sun, and how long it takes to recover.
Some real examples from customer projects, each sized with the interval and the worst month for that location:
| Site | Interval | Reserve with no sun | Full recharge |
|---|---|---|---|
| New Orleans, December | 60 min | 38 days | 1 day |
| Boston, winter | 104 min | 39 days | 2 days |
| Los Angeles | 34 min | 32 days | 1.5 days |
| Richmond BC, winter | 7 min | 18 days | 1.5 days |
Sizing is what makes those numbers work. Change the location, the month, or the interval and they change with it. A run of cloudy days slows charging without stopping it, and snow on a sloped panel usually clears itself with sun or wind.
Cold affects the battery more than the panel. Lithium charges more slowly below freezing, which is why we size for the darkest month rather than the average.
Watch shading across the whole calendar. A panel with full sun during excavation can end up shaded by the building it's documenting.
Photo interval drives power and data
Shorter intervals cost you twice: more power drawn and more data uploaded.
Most people new to long-term time-lapse guess an interval far shorter than they need. A 2-year project doesn't need a photo every 5 minutes. Run the numbers in our time-lapse calculator, which uses the same principles as Adobe's LRTimelapse, and it'll give you an interval that produces a good final video while staying inside your data plan.
At 60 to 90 minutes, solar capacity is almost never the limiting factor in North America. Below 10 minutes, calculate it properly before you order.
If you want extra frames during the build, capture them and delete every second or third image before rendering the final video.
Setup checklist
- Mount the panel separately from the camera. They don't have to face the same direction. One customer's camera faced northeast with almost no direct sun while the panel faced south.
- Check cellular signal at the exact mount position, not at the site office.
- Frame for the finished building, not the excavation.
- Use a fixed surface. No cranes, no temporary fencing.
- Use steel cable ties and tamper-resistant screws where casual access is possible.
- Save a reference image after final positioning so you can tell later if the camera has moved.
- Check the images daily for the first 2 weeks. Once power, framing, and uploads are stable, monthly checks are enough.
Maintenance
Less than people expect. Wind clears most dust from the panel, snow slides off a sloped surface, and the lens hood keeps bird droppings off the glass. An annual wipe covers it on most sites.
The image feed itself tells you when something's wrong. If uploads stop or the frame shifts, you'll see it in CloudX before your next site visit.
Frequently asked questions
How big is the solar panel?
About 1 foot square for a DataLens or SolarUp setup. It's small because a time-lapse camera powers down between shots. Continuous-recording solar security cameras need panels several times that size.
Does the camera have to face the sun?
No. The panel mounts separately from the camera and the two can face different directions. One customer documenting a Los Angeles remodel needed the camera pointed northeast at the house, so the panel went on the same post facing south.
How long does the battery last with no sun at all?
Between roughly 10 and 39 days, depending on the camera, the capture interval, and the location. A DataLens at a 60-minute interval in New Orleans holds about 38 days of reserve and needs 1 day of sun to fully recharge. A SolarUp with an external battery in Austin holds about 11 days and recharges in about 1 day. Run your own site through the time-lapse calculator rather than using someone else's numbers.
Will it work through a Canadian or northern US winter?
Yes, when it's sized for the darkest month rather than the annual average. DataLens is rated to -20°C and has run through Cape Breton winters below that. Lithium batteries charge more slowly in the cold, which is the actual constraint. If you're using SolarUp with a GoPro, check the GoPro's own temperature rating first, because it's more limited than the rest of the system.
What happens after a week of cloud or snow?
Charging slows without stopping. A panel mounted on a slope usually sheds snow with sun or wind within a few days, and the battery reserve is sized to cover that gap. On a correctly sized system a cloudy week is uneventful.
Does solar mean I don't need cellular?
No. They're separate systems. The panel and battery power the camera. A cellular modem or Wi-Fi connection sends the images off site. A solar camera with no connectivity stores images locally and you retrieve them by hand.
How much more does the solar version cost?
A few hundred dollars over the battery or AC version, depending on the camera. That's close to what an electrician charges to bring power to the same position, and it's a one-time cost.
Who cleans the panel?
Usually nobody. Wind clears most dust, snow slides off a sloped panel, and an annual wipe covers the rest on most sites. If the panel does get blocked, the battery level in CloudX shows the charge dropping before the camera stops uploading.
Can I reuse the camera on the next project?
Yes, and that's why some customers buy solar panels even for indoor cameras. A camera that carries its own power redeploys to any position on the next site without planning a circuit for it.
Can a solar time-lapse camera replace a security camera?
No. A time-lapse camera points at the building and captures scheduled images. A security camera points at gates and material storage and records continuously for insurance and incident response. Time-lapse systems do give on-demand live view for checking site activity, which covers remote project management without the power and data cost of streaming video.
