    Good size. 200 watts of panel gives me 1kwh per day. (Consider partly cloudy not real hot, morning fog) The 100 watt was way slow. Normally charges my 52volt battery at 2 amps and more in full sun.
    the included controller will not charge your bike battery. If you are going to use for rv and e bike, think about changing rv to 48 volt and using your e bike batteries for storage.
    solar panels have dramatically reduced my range anxiety. Mounted on the bike and charging while driving more than doubles my 13 wh battery useful range. This is a subjective observation that is based on my daily use.
    no more "can i borrow a cup of electricity"....

    I have been thinking of adding one of these to the solar set-up on my RV. https://www.lensunsolar.com/Products...product_id=381

    That's a fun idea! Living in The Netherlands, it's not utterly impossible either (same continent and all)...

    One day I'd like to get a foldable/collapsible/easily-storable/compact solar-kit (for off-grid camping), with adequate capacity for recharging my bakfiets' batteries.

    Sure--if I'm riding all day--I can't start recharging until dawn breaks on the following day--so that might mean two-days-per-campground for international cross-country adventures... But really? That might wind up just right--in terms of backside endurance.

    I have a lot of whacky ideas "on file" for my bakfiets... And cross-country adventures are on that list!

    Thanks, Jose!

    Oh, I really do love my bakfiets!

    Ah--but you know... You really do... After all, you've got that Cyclone powered Specialized beast too!

    Cyclones = grin-making goodness.

    My ridiculousness may know no bounds...

    (If I want to, I can fit one on each side, actually, and the weight would be more symmetrical... But it's a trike. It can handle it. No land speed records will be attempted while "piggybacking").

    But yeah. I can swap with my ex's for a "loaner bike" while I do some work on hers...

    One of my daughters gets hurt or tired, or needs to leave her bike somewhere, now--even carless--no problem.

    The side position does make me wider, but not a lot wider.

    Latest Conversion...

    Union Flamingo 6sp.

    Used bike: 35 Euros

    New tires (Schwalbe Marathon GT Tour 37-622 with new tubes), new jacket/skirt protectors, rear reflector and rear taillight lens (all three might as well have been NOS), new Union headlight, new "snelbinders" (elastic cargo-strap), new front-wheel mud-flap. Total parts cost: +/- 150 Euros.

    Some Self-Solves:

    I took an old LED fender-mount light, removed its guts, and used them to convert the original Union incandescent taillight to LED--to run off the TSDZ2's light-circuit (rear light visibility wasn't just matched, it was actually enhanced).

    I took an aluminum clamp-on style water-bottle holder, and adapted it to work as a new chain-guard support (yes--the newest TSDZ2 versions allow for some lateral adjustment of the motor--potentially allowing for reuse of original chain-guard brackets--but this motor was purchased before that update--so yeah. I think it turned out pretty beautifully myself).

    TSDZ2 48V 750W Mid-Drive kit 294 Euros (total price, taxes, shipping, etc).

    48V GTK (Uncle Ali) Lithium Ion battery 14 AH 285 Euros (total price, taxes, shipping, etc).

    This is my most satisfying bicycle conversion so far. The bike rides like the wind; and is practically silent. Its double-braced steel frame provides excellent rigidity. The seatpost battery position is directly beneath the rider, and maintains the bike's original balance perfectly. The bike rides like a dream-and it feels as sure-footed as a train on rails.

    Yes, this bike is in the neighborhood of "as old as I am"... That's a strong selling point, imo. If taken care of, this bike will also likely outlive me. This bike will certainly outlive the tens of thousands of miles available from its TSDZ2 mid-motor, and its battery... It is likely that if properly maintained, this bike will outlast many if not all its e-bike components--outlive many "reconversions" --whole new mid drive kits... Maybe it'll sport some mid-drive which have yet to come to market. Who knows what may occur as the decades fly by?

    Anyways...

    Durability is my friend... I guess that goes without saying.

    And for under eight-hundred euros, I've got a nice, but not-so-stealworthy bike that outperforms bikes here that sell for the price of nice used cars.

    Did you notice? Drum brakes! *Choirs of angels sing*

    Good luck with your projects everybody!

    take care,

    tklop

    Interesting idea, but a little paddleboat could just use a trolling motor instead. If we are going mad scientist, I think you would need to rig together a 100mm jet drive.
