I'm about to upgrade to a BCDC1240, and while I'm at it fit a larger capacity solar panel to the roof rack - probably a 120W - and the Redarc fixed panels seem to be competetive with the better panels on the market, and it would fit width ways on the rear of the rack.
But if I strap my (longer Mal) surfboard and sometimes other stuff on the rack and its possible that the board could partly cover the solar panel at the rear by maybe 10 or 20% of its surface area.
Q. How do the REDARC fixed panels perform for output when they are in PART shade ?
I've heard it said that for some types of solar panels, if they even get a small portion of shade, then half or even full power production can be lost ? Has to do with how the panel segments are internally wired apparently(series or parallel and number of banks) ?
Have REDARC got any figures or specs on output under various shade scenarios, inlcuding "solid" shade, or dappled light ?
