Can I get a real ELI5 on solar power? Probably to run a heat pump on a pool but maybe more.

I really do mean a complete idiots guide because I'm struggling to get my head around the jargon. Lots of videos and blogs I've seen just seem to assume a degree of knowledge that I don't have.

Currently (in Spain, south facing) I have solar hot water and can switch from that to a gas boiler for hot water. I didn't put the system in and I have no idea what it needs in terms of maintenance, but it works well.

I would like to put in pool heating using a heat pump powered by solar but I glaze over when (sales) people start saying, "well you need batteries and an inverterator and you'll need to generate 3 jibber-jabbers"

I think, if I'm installing it (not me) it makes sense to add parts of the house too. Maybe the aircon? If I do that, presumably I need something to connect to the main supply and switch? How do I know when I'm generating electric for "free"

So, for the pool, assume I've got a 22kw heat pump. I'm told I need a 10kw solar system but how many panels is that and what goes in between? If I want to run it to the house, what sits between the panels and the house to switch it.

For the record, I'm not bothered about selling back to the grid (I think that's been ruined in Spain by the power companies) I would just like to harness some power for me during the day

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6
