Here is my First Meshtastic Solar Node/Repeater... The Files contained within consist of 1ea) Solar Panel Upper Bracket, 1ea) Solar Panel Lower Bracket, & 1ea) Solar Node Pole Mount Bracket. It functions very well! there is a screenshot demonstrating the 70+ mile "MESH" that my repeater is part of. At 30' in the air (we are NOT on a hill) my repeater picks up "NO-HOP" a KNOWN and NAMED node more than 17 miles away. We have ALOT of trees and slight rolling terrain. The cost broken down by quantity needed totals approximately $157.00... Keep in mind i used a $60 antenna, a $20 battery, and some semi expensive connectors and such. Feel free to substitute parts as needed to save some cost. Please share your builds, and or any updates or changes you've made!

NOTES: I had some small "Melt In" Brass Inserts for PLASTICS. I used my soldering iron set to 750F as an install tool and I installed a Threaded Brass Insert into EACH of the four holes in the back of the BOX. Done CAREFULLY, they stay straight and strong. Using matching/mating screws, I GENTLY screwed the BOX to the "X" side of the POLE MOUNT BRACKET. I Mounted my box to the POLE MOUNT Bracket, on the same side as the Antenna. The Box and Antenna are mounted on the OPPOSITE side of the POLE MOUNT BRACKET from the Groove that sits against the "Pole of your choosing". I screwed the Solar Panel Brackets to my BOX using basically some short #6 PK screws/ wood screws/ Pointed Screws. I also had to lengthen my BNC Pigtail Wires that I soldered to the Panels, because with one center slot in the lower Solar Panel Bracket, the leads were too short. I used self adhesive electrical tie down pads to secure the leads/pigtails to the back side of the solar panels near where the wires solder on to them to provide support. Internally to the box, I wired the Panels in parallel to yield 5Vdc @ approx 600mAh. I did so by soldering a jumper from POS to POS to POS, and separately, NEG to NEG to NEG, then i soldered a Red lead from the center post on one of the BNC connectors, to the Positive IN on the Solar Control Board, I then soldered a Black Lead from the CASE GROUND on the BNC to the Negative IN on the Solar Controller. The battery plugged straight into the Solar Controller. For the Solar Board OUT to Power the Heltec, I robbed an old cheap USB-A end off a cable, and used the POWER pigtail that came with the Heltec, to make a USB-A to PH 1.5? adapter cable to power the Heltec through its Battery In port. Im not quite sure the reason, but the Heltec reports full voltage all the time now. Atleast until the battery dies during testing. Bright side is, the Solar Controller and the Heltec both power up by themselves after the battery reaches trigger voltage for the Solar Controller Input, in the event it ever dies from Gray Skies, fallout, etc....

DON'T CLAMP YOUR U-BOLTS SO TIGHT THAT YOU SQUISH YOUR POLE MOUNT BRACKET!!!
With the ABS and 50% Infill on the Pole Mount Bracket, it tightens up very secure and solid.

30% infill on the Solar Panel Upper and Lower Brackets was the INFILL % I went with. 50-100% infill on the Pole Mount Bracket, as you desire for strength.

Here is a list of components I used to build this Node. (AMAZON LIST) https://a.co/2A6zQyB

1ea) Junction box 1ea) ESP32 LoRa V3 Board. (But I'm going to build another with the Rak WISBLOK board to test power consumption. This board only lasts 3-5 days on the 10,000mah battery with no solar hooked up ) 1ea) 900 mA MPPT Solar Panel Controller 1ea) PH 2.0 Connector Set. (I used this to make quick disconnects in the circuit hookups.) 1ea) 10,000mAh Lipo 1ea) Waterproof BNC Bulkhead Connector to IPX 3ea) BNC Female Panel Mount Connectors 3ea) BNC COAXIAL Extensions (Pigtails) 3ea) 200mAh 5v Solar Panels/Photovoltaic Cells 1ea) Type N male to BNC male cable (3 foot) 1ea) LoRa Antenna (10dBi)
