@Gallo, I haven't bought these devices yet because I saw on Mikrotik
forums lots of people having trouble with these devices even at 50m
LOS. But I'm still curious and will get them sometime in the future an
test them.

Super awesome proposal Max, I'm happy to help
facilitate the development of
these prototypes as involves People's Open. I can help make sure the sudowrt
firmware works with whatever antennas you end up settling on (I have a
Nanostation Loco M2 I've been meaning to test).
Also something that may be of interest to you is the Mikrotik Wireless Wire,
https://mikrotik.com/product/wireless_wire
They are supposed to be very easy to setup, come in pairs, are relatively
cheap ($200 for a pair). While they are meant for short throws (~100m LOS)
and operate in the 60GHz spectrum, they do provide a full duplex gigabit
wireless link. Might be something to consider depending on how you plan on
deploying these repeaters. I've been meaning to order a few to see how
People's Open could use them.

Ok, here's what I'm thinking. The solar repeater would be more of a
temporary (months?) solution for people outside of the mesh's radius that
want in. It would be a link that mostly works during the day and sunny ones
at that. The people in the repeater chain would receive mesh internet for
some period if they want a permanent solution they can contact peoplesopen
and integrate with a home node. If not, we can always move the repeater
chain and try a new mesh tendril.
A solar repeater would be much quicker to set up, could be done with a 2
person team, and you wouldn't need to interact with the homeowner or go
inside their house. Possibly as short a setup as 30min vs 2hrs to to
integrate a home node.
Nanostation Loco M2 averages 3-4W? That's great news! The panel probably
needs to stay fixed at the 20W size, anything larger than that seems too
expensive and cumbersome to carry and mount without additional hardware.
Definitely need remote voltage and current monitoring Valent, good call.
Are we sure that MPPT is the way to go over PWM? Cost reasons number 1, but
I was worried that the additional micro-controller would eat the power that
was gained in increased efficiency for a low power application like this.
Jenny, I'm putting 2 of these together as a proof of concept, if the mesh
wants to cover expenses I won't say no :)

Max consider also adding INA219 voltage and current monitor. You can
connect it via i2c bus to most OpenWrt devices, or add additional ESP8266
that will use INA219 chip to monitor current and voltage.
If you don't have some kind of remote monitoring you will regret it
later, I talk from experience :)
Also using Grafana is great for this, you can see one of our latest
setups:
