Italian Solar Challenge Results

Above are official lap counts (in two stints) for the recent Italian Solar Challenge at the Imola Circuit near Bologna.

Bochum reported electrical problems with their SunRiser, and did not race, although they had successfully completed a qualifying lap (both Bochum cars had driven all the way to Italy). The local Italian team had even more serious electrical problems.

According to the regulations, for the Challenger class, there should be added to the scores above:

  • 2 laps for the fastest lap during the race (Aachen gets this, with a time of 4:09.236 in the first stint, i.e. 70.9 km/h for the lap)
  • 4 laps for the pole position in the qualifications (Aachen gets this too)

Consequently, Aachen’s lap score should, I understand, be adjusted up to 95.

Update: it seems that the organisers have decided to retroactively merge the two classes. Rankings are therefore:

  1. Aachen
  2. Bochum
  3. Solaris
  4. Solis-EV

Italian Solar Challenge now on

The Italian Solar Challenge is now on at the Imola Circuit near Bologna. A calendar for the event is shown above. Further details and team social media links can be found on my annotated teams list. See also the race social media at

Update

The start grid is shown below, courtest of team Sonnenwagen Aachen, who also have a livestream here. It seems that I was wrong in the pictures above; Aachen are racing only the three-wheel Covestro Photon. Bochum reports electrical problems with their SunRiser, which they expect to race only a few laps.


European Solar Challenge: Further Analysis

I updated my previous post to include visualisations of the official results of the iLumen European Solar Challenge. However, a helpful commenter shared a link to the detailed lap data, so above and below is some further analysis on lap times. Colours are the same as in the previous charts. As always, click to zoom.

The chart at the top shows pit time (including recharging time) as almost-horizontal lines, and pit time is also visible as gaps in the chart below. The histograms show that Top Dutch (6), the two cars from Sonnenwagen Aachen (7 and 70), Istanbul Technical University (34), and the experienced drivers in BOSolarCar e.V. (11) were particularly good at driving consistent lap times.

Measured by median lap times, Stella Vita from Eindhoven (41), Covestro Photon from Aachen (7), SunRiser from Bochum (11), RED E from Twente (42), and BluePoint from Agoria (8) were the fastest cars.


European Solar Challenge Lap Data

All too soon, the 24-hour iLumen European Solar Challenge is over. The charts above and below (click to zoom) show results from the live timing board. The winners of the two classes (Challenger and CR = Cruiser) will be decided on points scores, which are still to come. Meanwhile, however, the German teams from Aachen and Bochum deserve special congratulations. For updates, see also the race social media at    

Update 1: there are apparently no official results yet. All that has been released has been the podiums:

  • Challenger: 1. Covestro Photon (Aachen), 2. Covestro Sonnenwagen (Aachen), 3. RED E (Twente)
  • Cruiser: 1. Lodz, 2. Onda Solare, 3. Stella Era (Eindhoven)

Using the guidelines in the official regulations, I can calculate the Challenger class scores (see below).

Update 2: the official results have now been released, and I have added the chart below. Bochum seems to have lost out from having a two-seater car. For the rest, practicality judging makes up 40% of the final Cruiser score at iESC, so that Lodz essentially won on practicality (although I note that four of the Cruisers raced in Australia in 2019, and I would have expected both practicality and efficiency scores at Zolder to have been somewhat similar).


Sasol Solar Challenge Results

The final day of the Sasol Solar Challenge saw the teams arrive in Cape Town, with Delft (Brunel) in the lead after 8 gruelling days. Brunel’s fantastic performance is tarnished somewhat by the fact that a member of one of the South African teams threw a tool (?!) at Agoria’s solar panel last night, seriously damaging it. Without that damage, it is possible that the Belgians could have won.

The updated chart above incorporates some minor corrections to previous days. Not shown in the chart is UniChamps (University of South Africa), the sole Cruiser class team.

European Solar Challenge (iESC)

The iLumen European Solar Challenge in Belgium is about to begin – see my annotated list of iESC teams. The 24-hour track race will start at 13:00 on the 17th, continuing until 13:00 on the 18th. The image above shows Kratos EAFIT (from Colombia), Sonnenwagen Aachen (from Germany), Top Dutch (from the Netherlands), and Onda Solare (from Italy).

For fans at home interested in the weather, check the forecast. It looks like it will be rather wet, sadly. At the top of this page is a webcam nearby, looking west, towards the Zolder racetrack. This webcam is at the track itself (with a view of the “Kleine Chicane,” looking roughly north from just about the centre of the track). Circuit Zolder has a live timing board and tracker.

Sasol Day 7 / iESC begins

Day 7 of the Sasol Solar Challenge took the solar cars along the coast from Jeffreys Bay to Riversdale via Knysna and (optionally) Buffelsbaai. The Dutch and the Belgians are still-neck-and-neck, with the Dutch ahead by the tiniest whisker (10.1 km). Nail-biting stuff!

Meanwhile, scrutineering is beginning in Belgium for the massive fleet of cars in the iLumen European Solar Challenge (see my annotated list of iESC teams). I count 4 teams from the Netherlands (6 cars), 2 teams from Germany (3 cars), 2 teams from Turkey, 2 teams from the UK, and 1 team each from Belgium, Colombia, Italy, Poland, Sweden, and Switzerland. That’s 19 cars in total (10 Challengers and 9 Cruisers).

The 24-hour track race will start at 13:00 on the 17th, continuing until 13:00 on the 18th. For fans at home interested in the weather, check the forecast. It looks like it will be rather wet, sadly.

Sasol Day 6 / iESC begins

Day 6 of the Sasol Solar Challenge has seen some back-and-forth overtaking between the Dutch and the Belgians (in between roadworks), but the final position is the same as yesterday. Follow the Dutch at brunelsolarteam.com/race, the Belgians at live.solarteam.be, and see my annotated list of teams for team social media links. The official race social media is at      

Meanwhile, solar car teams are starting to arrive in Belgium for the iLumen European Solar Challenge (iESC). Naturally, I also have an annotated list of iESC teams. Scrutineering begins on the 15th. The 24-hour track race will start at 13:00 on the 17th, continuing until 13:00 on the 18th. For fans at home interested in the weather, check the forecast.

Sasol Solar Challenge Day 5

Day 5 of the Sasol Solar Challenge was a “blind stage,” where teams did not have advance notice of the route. There were no “loops,” so the gap between the Dutch and the Belgians is unchanged. North West University (NWU) gained some ground on Tshwane University of Technology (TUT). The totals in this chart are based on adding up official daily distances – for NWU, this does not seem to quite match the official total.

Sasol Solar Challenge Day 4

Day 4 of the Sasol Solar Challenge saw the Dutch ahead of the Belgians again, by a mere 29 km. North West University (NWU) in their unique car (pictured) is still trying to catch up to Tshwane University of Technology (TUT). Coming up next is a “blind stage,” where the teams are not told in advance what the route will be.
