An attractive feature, specially for children, is a model electric railway powered by PV.

Another novelty is an electronic set of bagpipes powered by PV (The driver is a piper).

When the van is on site, the solar water heating panels are folded outwards and connected to a bucket of water on the ground. The PV pump circulates water between panels and bucket and the public are invited to feel the water in the bucket. They are usually surprised to find that it is warm or hot, even on cloudy days.

4. Schools visits

Over the last two years, Solar One has visited nearly 200 schools all over Scotland. The normal programme is for a talk to be given inside the school, then groups of 10 or so pupils come outside to see both the inside and outside of the van.
