No perfect solutions here. But avoiding glass covered one for mobile applications would have to be a must. We started with the semi-flexible versions. A couple of players in this field. We used the following...

Great work on the Sonic 7 Kiwi. Most impressive build! That is one serious controller you are after. I found it hard enough to find a 56V MPPT system and it can only give 8 amps. Mind you on a Trike that's 'oodles'. We will keep an eye on your thread to see how you go. I have no idea if...

Hey ddk, good to see you have still been so active both in the forum and on the trike! Yep, 27 deg South makes a big difference. With the old Eco-worth panels, we were able to generate a 140+ W in ideal conditions (stationary trike with the array tilted towards the sun). Generally we were...

Sure. The array adds about 15kg. But it more than pays for itself energy-wise. The proof is in the pudding. Day 3 ride of CQ2013 looked like this: Many conventional riders thought one of the toughest days they had encountered. We survived it really well as we stayed "shaded" and monitored...

Never been an issue. Low profile + our total weight with both adults is around 200 kg + plus we are a cruiser, not a racer. Our CoG is naturally higher and it is advisable to keep it on 3 wheels when cornering (else Stoker gets narkey!). We get more wind effect on our motorcycle.

Been off forum for some time. Time to re-engage as we are solarizing our second trike. Our first effort (2013) is below. Specs are: Greenspeed GTT (including SS couples - packs away in a bike box - seats in a bag) 240W Solar Panels on custom made frame. Genasun GV Lithium Boost MPPT...

Wet thun - I will be interested in how it recovers - (note to self: "another reason to avoid water above rims, on top of 'pisses the stoker off when she gets covered both front and back'"!) Will be interested in your data - a good benchmark against our tandem. Would you mind supplying your...

Yes, sunny Queensland, Australia. State motto used to be "Beautiful one day, perfect the next". Lack of sunlight tends not to be the issue. The photos above were taken around the winter Solstice. Never. I don't claim to have any answers, only lots of questions..." What answers I do have I...

Yes, your handiwork is most impressive. Only something us 'mere mortals' might dream to achieve (in my case it would turn out a nightmare). For the lesser craftsman amongst us it is nice to achieve with off the shelf products and a little technical advice. I do like these newer lightweight and...

Correct. As a pedal assist, we are cruising at 25km/h on the flat using about 80W. So battery remains topped up for those "dang" hills. On an average grade we are pushing at 20km/h using around 300 - 400W. Interestingly, the torque sensor cannot pickup the stoker as she is only on my left...

Winter here currently, but we are peaking about 170 W of max 240W. Still to work out the watt hours, but our consumption and production during normal trips are equal. Now doing some hill trials and will post some numbers shortly.

A big thank you to this fabulous forum. With the fantastic info on this site we were able to achieve the following: Solar Powered Torque Sensor Pedal Assist - GTT. Full details are listed in the e-bike photos and video section, but I just had to share our joy (yes, that's my stoker in the...

Is there a better beast to convert to fully solar? Starting base: Greenspeed GTT. We have had this baby for about 10 years. Done lots of kms including a couple of 600 km tours. If people can carry canoes on their H-bars, why can't we carry solar panels? Current Configuration...

Thanks. While the throttle works fine as a standalone, when I route the throttle signal through the cycle Analyst, the voltage between the throttle signal and the +ve remains flat. Can't really make sense of it. Going to try another controller...

That is a good question. Currently the throttle is setup as Pass-Thru. It registers a throttle directly into the CA V3 and shows the appropriate change in output voltage. I can even register this change at the input pins to the controller. My next step is to change to Current Throttle, etc...
