Re: [WIRELESS-LAN] Solar Power AP Setup

[Philippe Hanset]

Jimmy,

We did such a project many years ago for a Gazebo fed through a point to point 
from a building.
It even worked at night during the winter (Latitude: Tennessee).

Here is a link with photos of the equipment.
The solar Panels have a Voltage of 12V and most APs these days can take 12V 
(our project was based on a Proxim AP-4000 that required 5V, hence the voltage 
converter).
So: solar panel 12V, AP 12V, Lead Battery 12V…all you need is a regulator 
between the Solar Panel and the battery!

Re: [WIRELESS-LAN] Solar Power AP Setup

[James Helzerman]

Hi.  Thanks unfortunately this is a solar research project and solar is a
required component.  Additionally the UM owned lighting has a single photo
sensor on a nearby building that provides power to the lights.  Even with
intermittent power charging the batteries at night will work, the concept
we are looking at is solar based.  Call it being green :)

Re: [WIRELESS-LAN] Solar Power AP Setup

[Daniel Eklund]

For a variety of reasons the only option for us at these locations is
solar.  We really would prefer real AC power, but it's just not available.

Re: [WIRELESS-LAN] Solar Power AP Setup

[Mike King]

Just another comment that solar might not be the best application.
I see in the archives you run Cisco.

Cisco has a whole line of outdoor Mesh AP's, that mount on streetlgihts,
and tap the power from the streetlight.  You unscrew the solar eye (the
thing that turns the light off during the day) plug in the streetlight tap,
and then plug the solar eye back into the tap.

RE: [WIRELESS-LAN] Solar Power AP Setup

[Paul Reimer]

If there is a powered light poll nearby it might still be a site you could 
consider for your AP. You’ve said that ownership would sometimes be an issue 
but they would give a high vantage point that could be beneficial to the bridge 
link but would also serve a wider area. I would also be concerned with the 
damage of the PV panels. You’ve probably also thought of it but the likelihood 
of someone climbing onto the roof of the bus stop (for a selfie, because; 
selfies, or whatever) and damaging the panels at some point is almost 
inevitable. That’s before you consider tree limbs falling, crews working in the 
area without regard, etc.. My concern would be that it would put too much 
hardware in reach of too many people.

I think there’s certainly cases for it and you might be on to one of them. I 
know we will all be interested to know how it turns out.

Thanks.  Most of our bus stops dont have power or lighting.  The light is 
provided by nearby street lights that don't have constant power.  Some are 
owned by the university others are owned by the city.

I have been looking into the terrawave solution and have a call in with their 
solar person and electrical engineer to go over the requirements and if it will 
work for us.

The backhaul would be 5Ghz Mesh with 1 Hop to the root AP.  For this proof of

the future with a Cisco AP that do FRA.

following particular questions but please add any comments or suggestions you

Questions:

What make/model solar system do you have?

What APs and antennas are you using?

What are the power ratings of the solar system (12v, 48v, 120v, wattage, etc.)?

How does the AP connect to the power such as a power injector running 120v, 
direct connect via DC, DC-to-DC converter, etc?

What is your targeted uptime?  Ie how long should the battery last in the event 
of bad weather.

Any other comments or stories to share would be most helpful.

The backhaul would be 5Ghz Mesh with 1 Hop to the root AP.  For this proof of 
concept 2.4Ghz is good for users but I would be looking to us 5GHz for both in 
the future with a Cisco AP that do FRA.

I have a question though. What’s your backhaul? Are you thinking of bridging to 
the bus stops?

Subject: [WIRELESS-LAN] Solar Power AP Setup

Has anyone used or currently have any access points powered by solar panels?  I 
am looking at doing a few proof of concepts at some bus stops to try and 
provide connectivity for those waiting for the bus.  I am interested with the 
following particular questions but please add any comments or suggestions you 
may have.

Questions:

What make/model solar system do you have?

What APs and antennas are you using?

What are the power ratings of the solar system (12v, 48v, 120v, wattage, etc.)?

How does the AP connect to the power such as a power injector running 120v, 
direct connect via DC, DC-to-DC converter, etc?

What is your targeted uptime?  Ie how long should the battery last in the event 
of bad weather.

Any other comments or stories to share would be most helpful.



Thanks,

-Jimmy

We aren’t running anything on solar.

I have a question though. What’s your backhaul? Are you thinking of bridging to 
the bus stops?
