Solar Panel advice request.

Probably the best first step is to assess what space constraints you have on the roof. There's no point in planning to have 150W (or whatever) of panel on the roof if it won't physically fit!

Now, back to your power needs. The first sentence suggests a moderate requirement:

And then the second sentence completely obliterates the moderate requirement!

Both of these will (probably) require an inverter and serious amounts of power. If those really are requirements then that will transform your installation - especially the hair dryer. Nobody is likely to want to use a hairdryer with a rating of less than 1200W, and many are near double that. Simple maths and the equation IV=W gives you a current loading of 100 Amps on the battery, which is not trivial.

So... I would suggest you need to decide whether those items really are requirements.

On a more general level, I would say that these days there is not a lot of point in considering a panel of less than 100W, provided you have space for it, and that outputs up to 150W are nowhere near as expensive as they were. We installed a semi-flexible150W panel and fairly basic solar controller in the Trooper, plus an upgraded split charge system, around 3 years ago now, and IIRC we spent less than £300 in total, DIY.

You could of course go bigger than that, with more batteries, though if your requirements really are moderate, you probably don't need to.
