I've been seeing a lot on Facebook marketplace lately - working second hand 250W panels for £10 each.

I don't have any immediate plans to add more capacity as I have too many other projects, but do people think it would be worth it for a DIY system?

Even if they are 20% less efficient than listed that's still 200w/£10, Vs 500w for £60. It would dramatically shorten the pay back period, but would produce less power long term.

I have a good number of trees in large pots, that I would eventually like to plant into the ground. Location is southwest UK.

The weather is currently a 'heatwave' (20-30C in the shade, very little rain).

If it matters the trees are a walnut tree, a Podocarpus salignus, a pinus Engelmanii, an apricot tree and a magnolia macrophyllum.

All have established roots and the pots are currently being watered daily due to the hot weather.

When is the best time to plant these out? My instinct says I should just plant them out now, as I will have to water then regardless if they're in pots or in the ground.

My wife says leave them in pots until the Autumn (Fall).

I don't want to risk losing them to transplant shock, but having them in the ground as soon as possible would give a much longer growing season for them.
