Solar Panels

Sunak and Solar

Detached from reality’: anger as Rishi Sunak plans to restrict solar panels.

Rishi Sunak plans to restrict the installation of solar panels on swathes of English farmland, which climate campaigners say will raise bills and put the UK’s energy security at risk.

Solar Powered Shade

Solar panels, if placed high enough can generate energy whilst at the same time providing shade for grazing sheep and cows beneath them. If you look at the surface of barns and other farm buildings it makes sense to replace the old roof, especially if it’s not beautiful patterned tiles, with solar panels. There is a barn near Ikea, in Aubonne that is covered entirely in solar panels. This is probably generating quite a bit of power for the local village.

Yesterday, out of curiousity I experimented. I charged both the Garmin Instinct Solar and the Garmin 45s with a solar panel. The first thing I noticed is that they were using 0.1 amps to charge, rather than 1, 2 or more amps of power. Until this experiment I had never considered how small batteries for gps watches are.

200 mah

According to a Google search the battery capacity of GPS watches is around 200mah. That’s tiny compared to the amount of power mobile phones and other devices have. This means that it’s easy to recharge the batteries on wathes like the Instinct, as long as you have a larger external panel or even a relatively low power external battery.
