The TMSC is happy to answer any questions relating to the regulations or any other solar challenge matters (Tasmanian or national). Simply head over to the website's CONTACT page and submit your query in the field provided or use the email listed.

Solar Freaks

If regulations or any other technical areas of either the car or boat challenges would like to be discussed then please also feel free to also join the Solar Freaks solar challenge forum and post a question there. Several Tasmanian and national committee members are signed up to this forum, as well as numerous competitors, and so a reply to a question can be expected within a reasonable timeframe.

Faulhaber 2232 motor update


A shipment of brand new Faulhaber 2232 solar car motors has just arrived and a small number of these are still availabler for purchase from the TMSC. These have been imported directly from Germany and, due to the bulk nature of the purchase, the TMSC is selling these motors at a cost of $75 excluding postage. This kind of price is unheard of in comparison to other local suppliers and places like Scorpio Technology are currently selling these same motors for over $166.

Contact the TMSC at miseli@utas.edu.au for more information.

Latest State Event News


Due to some complications there has been a date change for the 2013 Tasmanian Model Solar Challenge. This will now take place on Saturday November 9 at New Town HS and should give teams a few extra weeks to get their vehicles completed. This will consist of both the AIMSC car and boat events and more details will be released in the coming weeks. The date and location of the sprint car event has yet to be finalised although it is likely that this will also be held alongside the other two events on the same day.

The 2013 national event will be held at the Scienceworks in Melbourne on the weekend of the 23rd and 24th of November.

Given that the Tas website is also regularly visited by those from interstate, a colleague from WA has asked to have the details for the up and coming WA event listed. These are the details given to us thus far:

Western Australian Solar Model Car (Pursuit Event) & Boat Challenge
Proposed dates: 24th/25th October
Venue: TBA

Details to be confirmed at a later date. For more information on the WA event please contact Jun Guo at 20750946@student.uwa.edu.au

Faulhaber 2232 model solar challenge motors


The TMSC is currently in the process of finalising an order of Faulhaber 2232 6V motors directly from Germany for model solar car (or boat).

At this stage it's looking like a set of 20 motors will be purchased to help get the price down per unit. 10-15 of these will be going to schools down here in Tas but anyone from interstate is then welcome to buy whatever's left. If all goes well the TMSC is hoping that we'll be be able to keep the cost down to about $80 per motor which is basically half of what places like Scorpio are selling them for.

Just contact the TMSC at miseli@utas.edu.au if interested.

It's not yet clear how long it will take for the motors to arrive here in Aus, but it won't be before the NSW and QLD state events. It is however hoped that they'll be here before the end of September and so available for use in the Tas, Vic, WA and national events.

Model Solar Car and Boat Help in 2013


For students, teachers and teams seeking out help with their solar cars and boats this year be sure to check out the information and help files provided on the website's CHALLENGE HELP page or feel free to send the TMSC team an email asking for some assistance.

Last year's national champions from New Town HS used much of the information on this site to great effect in the design and construction of their winning model solar car.
More content as well as 2013 updates on certain areas and files will be added in the coming weeks/months.

Still on the topic of model solar car and boat help, the TMSC is in the process of organising a help workshop for teachers and mentors interested in getting involved in the 2013 Tas solar challenge. Further information including dates and venues will be published once details have been finalised.

For students and teachers that hail from interstate, feel free to drop the TMSC team an email if you require assistance of any kind. The TMSC team has a wealth of challenge experience, as well as many contacts on the mainland, and so should be able to answer almost any challenge related question/s you may have.

Below is a short mashup of 2012 solar car video footage that was recently put together by a member of the TMSC.



TMSC goes RC???




A new remote control solar car and/or boat division could soon be added to the Tasmanian Model Solar Challenge in the future.

The TMSC is currently looking into the feasibility of running such an event as well as potential competition rules.
Given that an RC solar car challenge already exists in Victoria/NSW it is envisaged that the TMSC will align a Tas event with this so as to then allow top teams to be sent up and compete on the mainland. Watch this space.

Pictured above is a simple 2 Channel RC solar car that has been put together by a TMSC committee member. Some videos of the car in action will be posted shortly.
The car has a 10W solar panel, Faulhaber 2232 motor, Automax and RI drive wheel onboard as part of the drive system (all typical components on a standard AIMSC model solar challenge car). The RC receiver, steering servo and receiver controlled on/off switch are powered by a separate small capacity 7.4V LiPo battery and UBEC.

New Low Cost 10W Ebay Solar Panel



In late 2012 the TMSC stumbled across a new low cost 10W solar panel on Ebay. These panels cost less than $30 and weigh just 350g.

Not being able to ignore such a promising panel for the solar challenge the TMSC decided it had to investigate these a little further. As such, several were ordered in over the New Year and this revealed the following:

1. Sound panel quality. As a whole, the panel feels appropriately rigid and should easily be robust enough for a model solar car.
The type of cell encapsulation appears to be the same as the old Disk Smith modules which looking promising from a cell-cracking perspective. This is because the encapsulation is made from a softer compound allowing the solar cells to expand and contract with changes in temperature, unlike is the case with modules using a harder form of encapsulation (ie the Engelec modules for example).
For those of you familiar with the old 1.5V Dick Smith modules, these new panels are essentially 12 of these in series but as one panel.

2. Below optimal Fill Factor. Initial testing has shown these panels to have Fill Factors of around 0.71-0.72. This is lower than most panels used by cars competing in the model solar challenge these days and most Scorpio panels, in comparison, generally have a Fill Factor of about 0.75-0.76.
This isn't necessarily a bad thing though and the series/shunt resistance balance is really all that is important to car teams. As long as panel power remains reasonably linear with sunlight % then having a slightly lower FF, and therefore power output, won't matter since the car will be ballasted accordingly.

A couple of panels are currently on the way up to Ian Gardner in Victoria for some more comprehensive testing and results will be uploaded here once they become available (keep tuned).
Should results turn out to be favourable, the TMSC would be happy to recommend such a panel as a low cost alternative to the more expensive Scorpios. A car panel made from Scorpios will cost upward of $150 whereas 4 of these Ebay panels cost the TMSC just $84 including postage (that's $21 each!!!).

The voltage of these panels is perhaps a little on the high side but is still fine for teams running with electronics. They may not be ideal for running without electronics as they are but modifying them for series/parallel can still be achieved quite easily through some simple panel mods. The panels could even be cut down to lower the voltage in order to be more suitable for running without electronics.

2012 Sprint Car Challenge


The 2012 Powercom Solar Sprint Car Challenge will take place on Wednesday November 21 at John Paul II Primary School (161 Mockridge Road, Clarendon Vale).


View Larger Map

The event will be held on the oval at the side of the school which can be accessed via a track by the side of the driveway when entering the school. It is envisaged that there will be parking allowed for teams and officials on the edge of the oval on the day.

Team registration and scrutineering will kick off at approximately 9am. Given that teams will be getting to the venue at different times it is suggested that teams make their way to registration and scrutineering upon arrival. This should ensure a constant flow through the scrutineering process and allow for racing to get underway as soon as possible. Teams that have been scrutineered will then be welcome to test their cars on the track before racing commences.

Racing is expected to begin at approximately 10:30-11:00am and will then consist of a grouped round robin format where cars will compete in a series of races against other cars in their group. Teams with the most number of wins will then go on to compete in the finals which will take place at around 1pm.
An awards presentation will then follow shortly after all racing has been completed and the whole event should be completed by close to 2:00pm in order to give teams enough time to get back to their respective schools by 3:00pm.

John Paul II will be running a BBQ and drinks with sausages and burgers will be available for purchase throughout the day.

Teams that have yet to register for the event are encouraged to do so using the online entry form although on-the-day entries will still be accepted.

Finally, it is advised that teams pack some warm clothing, a raincoat, sunscreen and a hat to cater for all weather conditions.

Please contact the TMSC at the details provided on the website's CONTACT page for any further information in relation to the event.

Good luck to everyone and let's keep our fingers crossed for some good weather,

2012 TMSC Event Update


Despite the dreary forecast for tomorrow's state event, the model solar car challenge will still be going ahead as planned. A basic layout of the day can be downloaded below:

2012 TMSC Schedule

Please note that times are only approximate and that the weather is likely to effect racing. Short breaks in the race schedule may be implemented during periods of rain.

2012 TMSC Event Date Change


Due to a series of unforeseen circumstances the TMSC has been forced to move the 2012 state event to a new date.

After some negotiations with participating schools and committee members, the state championships for the AIMSC cars and boats will now be held at New Town HS on Thursday October 25th (Hobart Show day) as seen in the following flyer that was handed out at the Spring Community Festival.

2012 Solar Challenge Flyer

Several schools involved in the Sprint Car Challenge have asked for more time to complete their vehicles and so this competition has been moved to a separate day later in the year. This will be held at John Paul II Primary School (one of the participating schools) in Rokeby on Wednesday November 21st. This later date is only possible given the competition does not have a national event for which teams need to qualify (the national event for AIMSC cars and boats is being held in Melbourne on the 24th and 25th of November).

Please note that teams competing in the Sprint Car Challenge will not be required to attend the earlier state championships for AIMSC cars and boats but are encouraged to come along and see the more advanced cars in action.

A more detailed schedule of events will be released a little closer to the competition dates and the TMSC apologises for any inconvenience resulting from these changes.

New Circular TMSC Test Track and 2012 SCF



The Tasmanian Model Solar Challenge recently attended the 2012 Spring Community Festival at the Royal Tasmanian Botanical Gardens after being invited to set up a display by Festival and TMSC sponsors, Powercom. This invitation prompted the construction of a new, small and easily portable test track (seen above) and it is envisaged that this track will come in handy at many future demonstrations/exhibitions.

Below is some video footage of a car running around the track at the festival in reasonably good sunlight.



The track guide channel has a radius of 3.5m making it currently about 22m long. The TMSC is however looking to add some straight sections in the near future and extending its overall length out to somewhere between 30m and 40m with the possibility of then running a pursuit-style practise event earlier in the year for teams to test their cars.

In a pursuit race cars run around the single lane track in the same direction, starting on opposite sides, until one catches the other. As seen in the video below, cars that are similarly matched can require quite a number of laps for this to eventuate.



The TMSC makes the Sunday Tasmanian


A short newspaper article on the Tasmanian Model Solar Challenge was recently published in the Mercury's 30th September Sunday Tasmanian, alongside a story on major sponsor, Powercom, for the up and coming 2012 Spring Community Festival.



TMSC Helix car



This car was once commissioned by the CSIRO Education Double Helix Science Club as a demo car for the Tasmanian Model Solar Challenge and has been used as a benchmark for Tas cars to beat in the past.

The TMSC is currently seeking out a school that may be interested in getting involved in the Challenge in 2013 and would like to gain some competition experience by racing the Helix car at this year's state championships.

Please contact the TMSC at the details provided on the website's CONTACT page for further information.

GWS gear boxes and Low Cost Maxons for Sale




A limited stock of Grand Wing Servo-Tech (GWS) LPS 6:1 gear boxes ($15) + motors ($5) has arrived. These are a light weight indoor RC plane gear box but are also suitable for use in the model solar boat challenge, particularly the junior division where there is a limit on motor cost ($5 in 2012).

3 of the top 4 junior boats, including the winner, had a GWS gear box or similar installed at the 2011 national event. Similarly, the winner of the 2010 junior division also used a GWS unit.

Although the motor used in the GWS gear box is not as efficient as a precision coreless motor such as a Maxon or Faulhaber (max eff. of around 65% compared to 85%), it is well matched with a Scorpio panel and will operate at close to max efficiency at max panel power in higher sunlights when the panel is connected in series and the correct propeller used (a 35-40mm dual bladed prop may be a good starting point for testing). The gear box generates a higher prop shaft torque than standard hobby motors, allowing a larger and more efficient propeller to be used.

For best performance in low sunlights the Scorpio panel will need to be switched to a parallel configuration and the correct propeller chosen for max power transfer. Testing both panel configurations and various prop sizes will help determine the best setup at intermediate sunlights.

Combined, the gear box and motor weigh approx. 21 grams which is lighter than many hobby motors on their own.

Due to the high level of shaft torque, the coupling between the gear box and propeller shaft will require some special attention in order to eliminate slippage. Gluing the commonly used flexible coupling to the gear box shaft may suffice.

The gear boxes + motors are available from Jun Guo in W.A. for $20 each ($5 motor and $15 gear box) + p/h. To order or for further details please contact Jun by email at: guoj07@student.uwa.edu.au



Jun also has a number of low cost 4.5V maxon motors which are available to advanced boat or sprint car teams. Contact Jun for more information.

2011 AIMSBC Boat Data and Results


Below is the boat data and knockout results file from the 2011 national event held in Hobart:

2011 AIMSBC Boat Data and Results

On another note, the 2012 boat regulations should be released in late January/early February.
At this stage the major expected change from last year will be the removal of the ballast which was required in 2011. The $50 limit on Junior division motors may also be reduced to $20 (with any coreless motors under $20 also being outlawed).

Solar Panel Cracking

In other news, the 2012 car rules will be released shortly as there won't be a great deal of changes for next year.
The major rule change will be a reduction of drag plate area down to 150 sq cm. Rather than specifying this area to be rectangular (as was the case this year), the committee is currently looking into the idea of allowing any shape but requiring this to be made up of aluminium sheet metal.
Instead of having to measure areas, scrutineers will then simply weigh drag plates to determine whether or not the required area has been met.

Below is a TMSC flyer that was recently sent out schools detailing the dates for this year's Tas events.

2011 Tas Solar Challenge Flyer

As the flyer outlines, all three of the Tas sub challenges will be held on separate days.
The main car event will be held at an earlier date (Sunday October 16) at New Town HS in order to give teams that will then be going on to represent the state at the nationals some time to fine tune their vehicles.
The Tas boat and sprint car challenges will instead be held in conjunction with the national event at the University of Tasmania Rugby ground, Sandy Bay on the 26th (sprint cars) and 27th (boats) of November.

Schedules for the various events will be issued at a later date.

2011 AIMSBC and TMSBC Regulations


2011 Model Solar Boat Regulations

Apart from a few wording changes here and there, the key difference between this and last year's boat rules is the addition of a dead weight (cargo) which will need to be carried while racing. Please see the above regulations for details (section 5, part 12).

Although a number of states may not abide by this new rule for their state event, it will be enforced at the 2011 Tasmanian and National model solar boat challenges.

Please note that all Tas boat teams will be required to produce a simple poster for the boat event as has been outlined in section 2.6 of the rules. This is because all Tas boats will be automatically entered into the national event which will be doubling up as a Tas event in Hobart this year.

The 2011 Tas and national boat challenge will be held on Sunday 27th November (the day after the sprint event and second day of the national event) at the University of Tasmania ruby ground, Sandy Bay, Hobart in conjunction with the national event for AIMSCC cars.

This is the 2011 update of Ian Gardner's model solar car design hints document. Although quite lengthy, it contains many great hints to build a good quality car as well as good background information on virtually all areas related to the model solar car challenge.

Model Solar Car Design Overview


Model Solar Car Design Overview

This document is an abbreviated version of Ian Gardner's design hints and includes some details and photos of the car that won the 2009 Victorian event.

The Sprint Car Challenge - As easy as playing with Lego


For last year's challenge a member of the committee constructed and raced a car made up entirely of Lego and Lego Technic (excluding solar panel, wiring, switch and motor) to help demonstrate how simple it can be to build a working car. Some photos of the car and a short video clip can be seen below.





Note that this car has been given steering trolley wheels in order to also run on the main car figure 8 track. This would not normally be required for a sprint car since the competition is held in a straight-line drag race format.

2011 Sprint Car Regulations

2011 update
The new sprint car rules have been left unchanged from last year and schools competing in 2011 may re-enter previous cars if desired although modifications to improve them is encouraged.

The 2011 sprint challenge will be held on Saturday 26th November at the University of Tasmania ruby ground, Sandy Bay, Hobart in conjunction with the national event for boats and AIMSCC cars.

New 4 cell Solar Modules Test Data


The new 4 cell modules have recently arrived and intial testing by Ian Gardner in Victoria has given the following results:

50% Sun, 25C, AM1.5, 10 series modules.

Voc: 23.50 Vmp: 19.49 Imp: 0.241 Isc: 0.254 Pmax:4.70 FF:0.787

100% Sun, 25C, AM1.5, 10 series modules.

Voc: 24.37 Vmp: 19.75 Imp: 0.464 Isc: 0.491 Pmax: 9.16 FF: 0.765

For less modules simply factor voltage and power.

These figures suggest that the modules are of a very high quality. Further test results and panel IV and power curves can be viewed by downloading the document below.

NEW 4 CELL MODULE TEST RESULTS

The modules have come in two different cell widths. The above figures are for the 28mm wide cells but there are also modules with 25mm wide cells where the output can be approximated by simply factoring the above current and power figures by 25/28. The different cell sizes are not mixed on modules and John has sorted out the two versions.
This gives teams a further option when selecting panel powers.

Contact John for further details and purchase. John's contact details are listed on the website's CONTACT page.

New 4 cell Solar Modules

NOTE:

These modules have the same dimensions (62mm x 120mm) as the 3 cell modules listed further down. They are made from the same first quality, laser etched and anti-reflective coated cells and black fibreglass backing, but the 4 cells take up more of the available module space. The extra cell will increase the voltage of each module from approx. 1.5V to 2V and the reduced size of the individual cells will result in a lower module current. The overall power output from the 4 cell modules will be slightly greater. Full test data will be available shortly. The physical 3 and 4 cell modules can be compared below.

4 cell solar module 3 cell solar module

John Jeffery has arranged to have these made specifically for the solar car challenge and the first shipment is scheduled to leave China on the the 15th of May. Due to having more active cell area plus the extra handling in mounting the extra cell, the 4 cell modules are going to be marginally more expensive. The extra voltage, however, will mean that only 8 modules rather than 10 will most probably be required for a car panel. The modules are expected to cost around $14 + GST and orders will be taken in advance.

Contact John for further details and purchase. John's contact details are listed on the website's CONTACT page.

Solar Freaks

This forum has been up and running for the last couple of years now and is a great place to discuss and seek help with regards to the solar challenge.

New Solar Modules

NOTE:

These are 3 cell modules with the same dimensions (62mm x 120mm) as the original DSE modules and are about the same weight (around 33gm). The cells are epoxy encased on a black fibreglass base with two polarity marked solder pads on the rear. The modules are not made from rejects and left over scraps but are purpose made from first quality cells. The actual cells are all rectangular (no missing corners) and have been laser cut from larger 125mm x 125mm isotropically etched and antireflective coated cells. The original Taiwanese made cells are graded to ensure consistency and only the top 2 grades with quoted efficiencies of over 16% are used. The Fill Factor of the cells as quoted and tested is around 0.75. The original samples that were sent to Ian Gardner for testing were given the thumbs up.
