1. Does the site have to deal with snow? Will panel need to have snow removed?
2. Select a series pass regulator, rather than a shunt regulator. My son built a small solar system, using a shunt regulator & I think it cooked the solar panel. After 15 years, the panel has turned from a blueish color to brown. Output has dropped to about 25% and there appears to be a couple cells which look like portions may have melted the tiny conductors under the glass.

Hi All,

I have a situation where I might need to power a Ubiquiti hop site with some type of solar/battery/inverter setup.

It's just two PoE radios, rated at 5.5W power consumption each (120V into PoE adapter).

I'm looking for something I can attach to the wood pole that supports the antennas, that is, to fit in a small cabinet that will attach to the pole. I'm OK with assembling this from parts rather than some kind of turn-key kit but the simplicity of a kit would be great because I'll be doing this as part of a big project and there's a lot on the plate while the project is in process.

I'd be interested in hearing from folks who might have done something like this -- it's much lower power requirement than a solar powered transmitter or translator site but it needs to be reliable (STL). I envision a deep cycle battery connected to the charger/inverter, or other battery technology that makes sense.

The panel would have a nice south exposure maybe fifteen feet up the pole, but the cabinet would be sheltered much of the day as it would go below the roof level of a very nearby adjacent building. That means not much roasting in the summer but we do get to -25F in the winter so if anybody has some real-world experience with battery technology for this I'd be grateful for the input.

Trenching power to this location would be very costly so I think doing our own solar might just be a great self-contained alternative.

Thanks for any real-world experience you can share.
