Having just bought a Bessacarr e495 I want a solar panel fitted asap. I haven't got the time to think about doing it myself within the next few weeks so I'm going to ask some technicians. But which panel is right? And how much do they cost? 90w or 120w seem to be common. I imagine it's a case of the bigger the better although weight is an issue. There's only one leisure battery so I'm guessing I ought to but another. Any advice appreciated.
