Hi,I would love to have a panel with a satellite tracking motor as used for amateur radio to see how directional they are. There is so much miss-information, who does one believe?
I know we had a 30 watt wind charger or a 10 watt solar panel as the two options to power an electric fence, with a car type battery. And the sheep got through the wind charger powered fence more that the solar powered fence, as only snow stopped solar working during the day, but even in the Falklands known for wind, the batteries went flat more often with a wind charger.
However the small using used to maintain the caravan battery when in storage failed. OK there was a problem with the radio, if power removed and restored the radio went into demo mode, so once the battery voltage dropped once, that is it, the radio ensured it would never recharge it.
I have a remote control drone antenna tracker, which would work to control a panel, but I though about it and it can be done much simpler.
The sun's direction is predictable, so a simple slow worm drive would do, with a return. The elevation, could be a long cam type mechanism, that can be changed for a higher profile in summer etc.
PV and wind trubine calculations are difficult, because of the variations.
Re: 'the fence' with some monitoring, it may be possible to heat the panel and melt the snow, but that is specialist and best tested individually.
