Off Grid Power for Telecom Tower Sites
Powering a portfolio of tower sites is a different job from choosing a system for one location and repeating the order. Site loads, sunlight, installation conditions and maintenance access all vary across a route, so the practical approach is to group similar sites, pick one standard system for each group and flag the locations that need separate sizing. This page works through off grid power for telecom tower sites in that order, starting with the site types before the arithmetic. The systems discussed here serve the 12 V auxiliary equipment at the foot of the tower, not the operator’s main transmission equipment.

Q: How do you power telecom tower sites off grid?
A: Start by sorting the portfolio into site types rather than sizing each site on its own, because a site that has a grid connection which fails, a site with no connection at all and a site already carrying a generator need different answers. Then list what actually runs at the foot of the tower, keep the total continuous draw inside the 60 W output ceiling, and pick one standard model that covers the majority of sites so the installer, the spare and the paperwork stay the same everywhere. Sites that fall outside that model are the exceptions worth handling individually.
Four Site Types, Four Different Jobs
The same tower can need three different systems depending on what already exists at the fence line. Sorting the portfolio this way usually collapses more sites into one category than owners expect.
| Site type | What is already there | What the solar system is doing |
|---|---|---|
| Grid present, supply unreliable | A connection that drops for hours or days at a time | The point draws from the system directly, so short grid gaps do not take it down; the connection itself is untouched |
| No connection at any distance | Nothing, and the nearest transformer is not coming | Carrying the point on its own, sized for the worst month |
| Generator on site | Fuel deliveries and a scheduled maintenance visit | Running the point from solar instead of generator output, which removes that draw from the fuel budget |
| New build, not yet powered | A foundation and nothing else | Going up with the site instead of waiting in a queue |
The fourth type is the simplest place to make this decision, because the mast, the enclosure and the visit are already being paid for once. Retrofitting a point that has been running on something else is a different job with a different set of constraints.
What Sits Below the Tower, and What These Systems Do Not Touch
This is the part that decides whether a page like this one is useful to you, so it goes early. Our systems deliver DC 12 V with a ceiling of 5 A, which is 60 W at that voltage, through a 5.5 × 2.1 mm DC plug. Anything at the site that runs from 12 V DC inside that ceiling is in scope. Equipment that needs a different voltage, or a supply of its own kind, is not, and a tower’s own transmission gear is rarely a 12 V load.
That leaves the ring of equipment at the foot of the tower, which is where most tower-site failures actually land: the camera watching the compound, the gate contact, the link that carries the footage, the light that comes on when someone is where they should not be, and the small environmental box that reports temperature and door state. Those are ordinary 12 V loads, they run continuously, and they are the load a solar point at a tower is usually built for.
These systems are intended for 12 V auxiliary equipment at the tower site, such as cameras, routers and sensors. They should not be specified for a tower’s main telecommunications equipment unless the required voltage, continuous power demand and backup requirements have been verified against the system specifications. What we supply is a standard solar power system with a DC 12 V output and a stated ceiling.
What Usually Runs at the Foot of a Tower
Figures here are planning estimates for the equipment that typically sits at a tower site. Confirm each one against the label on the unit you actually have before you commit to a size.
| Device at the site | What to assume at first | Where the figure comes from |
|---|---|---|
| Compound or gate camera | About 5–10 W continuous | The model’s own specification, then one measurement at the plug |
| PTZ watching the access track | The upper end of that band, plus bursts | Pan and tilt add peaks on top of the baseline, longer at night |
| Router, radio or CPE carrying the footage | About 3–12 W, and it never idles off | Measured under load at the site rather than on a bench |
| Gate contact, sensor, small switch | Count each one separately | Its own label, kept apart from the camera figure |
| Illuminator or flood light | Only if it runs on the same supply | Night use only, but at several times the camera draw |
A site list built from labels alone tends to come out high on the camera and low on everything else. The figure worth carrying into a purchase order is the one measured with the point running the way it runs in service.
One Standard Model Across Many Sites
Using several different power systems across a network adds installation time, spare-part variety and maintenance complexity. Where site conditions allow, standardizing the equipment makes it easier for technicians to follow the same procedures and carry matching replacement units. Sites with higher loads or different mounting requirements should be assessed separately rather than forced into the standard. The side-by-side comparison of the four standard sizes is the shortlist worth standardizing from.
The practical approach is to size the middle of the portfolio, not the extremes. Take the busiest ordinary site, add a margin for a second camera that will probably arrive later, and choose the model that covers that. Most of the route then runs on one SKU that everybody has already seen. The two or three sites that fall outside it are worth handling on their own, and they should be named in the plan rather than discovered on site.
Sizing for the middle also makes the exceptions visible, which is the point. A site with a flood light on the same feed, or a site with a second mast, announces itself during planning instead of after the first flat battery. A hotspot at the gate is one of those announced loads, and powering a site hotspot is itemised on its own page. Loads that already sit at a site are worked through separately in what a camera really draws. The router on the same mast is a load in its own right, worked out in what the link adds to the budget.
How to Choose a Pilot Site for a Multi-Site Rollout
Choose a pilot site that represents the more demanding conditions in the planned rollout: distance from the maintenance depot, local solar conditions, expected equipment load and access for service visits. A site that runs well under favourable conditions says little about how the rest of the fleet will behave in a bad month.
Run the pilot under normal operating conditions and record actual energy consumption, battery performance and any periods of insufficient power. An initial month is a useful observation window, but it cannot cover the region’s worst sun and longest cloudy stretch, so check the recorded figures against historical sunshine and the reserve arithmetic before copying the configuration to the other sites. Minimum order is 2 pcs, so a pilot and one spare is a natural first purchase.
Where the points are spread along a route rather than inside one fence, the method is set out in power planning along a corridor, where pipelines, mines and highways raise the same question about how far apart the points sit.
Mounting Without Touching the Tower
A tower belongs to someone who will want to inspect it, and adding brackets to it means paperwork, engineering sign-off and a conversation with a company that has no reason to hurry. Every one of those conversations delays a rollout, and at every site on the list the delay repeats.
So the practical answer is to mount beside the tower rather than on it. That means an independent mast inside or outside the fence, a wall or base where one exists, and a pole bracket where nothing else is available. The tower keeps its structure and its inspection record, and the solar point gets an installation that a two-person crew can repeat from site to site without a crane and without touching the asset.
Where the load is small and the site has no wall within reach, the pole-mount version of the standard system carries the panel, the battery and the equipment on one structure. A site with a base or a wall can use the wall bracket and keep the mast short, which is also easier to repeat across a route.
Which Model Repeats Across the Route
All four deliver a DC 12 V output with a rated current of 5 A. What differs is panel capacity, battery storage and how the system mounts, which is what decides which one becomes your standard.
| Model | Solar panel | Battery | Output limit | Typical role across a portfolio |
|---|---|---|---|---|
| YO-M8040 | 80 W | 40 Ah · about 326 Wh usable | DC 12 V / 5 A | The light site, and the easiest one for a small crew to repeat without lifting gear |
| YO-P12060 | 120 W | 60 Ah · about 490 Wh usable | DC 12 V / 5 A | The usual standard for a camera plus a link at an ordinary site |
| YO-P12060-T | 120 W | 60 Ah · about 490 Wh usable | DC 12 V / 5 A | The same load where there is no wall to bolt to and the mast carries everything |
| YO-P240120 | 240 W | 120 Ah · about 979 Wh usable | DC 12 V / 5 A | A heavier daily energy budget or long low-sun periods, not a higher output |
Usable energy follows a stated basis: 12 V nominal, with the reserve the system keeps in hand and the conversion loss already taken off. How far that reserve carries a given site depends on the total draw, the panel’s daily input and the sun that region gets, so read the last column as the start of a conversation rather than a finished specification. Once the typical site load and local solar conditions are confirmed, the selected configuration becomes the starting point for similar locations, which is how off grid power for telecom tower sites stays manageable across a whole route. Any site with a higher load, limited sunlight or different mounting conditions should be reviewed before the same model is specified.
