Although the Milan airport Malpensa is not the nicest place to be, it is just an airport and 50km (!) from Milan city centre, it was exciting last week; being the venue of the Solar Asset Management Europe conference. It was also a perfect platform to present our DustIQ Soiling Measurement System.

The pressure has been on, but RT1 is ready to roll!

When we introduced the RT1 Rooftop Monitoring System at Intersolar in Munich we were aiming at commercial availability within 4 months and I’m happy to say we have succeeded! RT1 is now ready to order.

Customers in Asia and in Europe have purchased and received the very first RT1’s and are testing them. Soon we’ll be able to share with you their findings.

Re-calibration: a matter of good maintenance practice

[fa icon="calendar'] 3-okt-2017 13:30:00 / by Jan-Willem Sips posted in Calibration, maintenance

[fa icon="comment"] 0 Comments

On evenings and weekends with beautiful weather, I tend to jump on my old-timer scooter and ride the winding roads in the neighbourhood. The scooter is from 1962, and my father used to drive it to work in the sixties. It is still rolling along due to its high build quality and my ongoing good maintenance.

You might have read that the oldest operational Kipp & Zonen pyranometer we found is located in Freiburg (Germany) and 46 years old. Like my scooter, it is still operational due to its build quality and good maintenance! You have to clean the dome, ideally at least every 2 weeks (or as soon as it gets dirty) and at the same time check the levelling and inspect the desiccant colour (and change it when required). With many of our recent instruments you don’t even need to check the desiccant, it is sealed inside.

Part of pyranometer maintenance – and luckily not part of old-timer scooter maintenance – is regular re-calibration. Under the influence of solar radiation, mostly the UV light, the sensitivity might have changed slowly over time.

Global operation, local calibration!

[fa icon="calendar'] 22-sep-2017 14:26:47 / by Jan-Willem Sips posted in Calibration, global, international, india

The world of utility-scale solar energy is becoming a global market; many investors, asset managers, EPCs and O&M parties operate on an international scale, or they intend to do so.

Many of the parties I meet have global strategies and policies and they buy centrally to benefit from large volume prices. An example is a German monitoring firm, which installs worldwide, but puts all the monitoring elements together in Germany and tests the systems before shipment.

People are at the core of all companies; they are the heart that circulates oxygen, the brain that decides on the best path to take and the spirit to convince the world of their company’s added value.

46 year old CM5 pyranometer wins the pyranometer hunt

[fa icon="calendar'] 23-aug-2017 13:55:00 / by Kelly Dalu-Karlas posted in pyranometerhunt, pyranometer

Earlier this year we opened a competition to find the oldest pyranometer still operational in the field. Now that the competition has closed and we have sorted through all the applications we can announce the winner is a CM5 from 1971. You probably want to know more, just like me, about the history of this pyranometer that originally started measuring in Canada and ended up in Germany for a second life.

DustIQ soiling measurement as simple as 123

[fa icon="calendar'] 20-aug-2017 13:15:00 / by Donald van Velsen posted in DustIQ

While finalizing the last details of DustIQ I’m also getting ready to show it at some key events in solar energy: Intersolar South America in Sao Paolo, Solar Power International in Las Vegas, the European Photovoltaic Solar Energy Conference and Exhibition in Amsterdam and Solar Asset Management in Milan. What I’ve learned so far at events is that we can talk about it for hours, but DustIQ is actually fairly simple in principle.

A busy week in Bangkok

[fa icon="calendar'] 20-jul-2017 12:17:52 / by Clive Lee posted in DustIQ, Calibration

[fa icon="comment"] 0 Comments

Last month I had a very interesting visit to Thailand.

We have a new distributor for the country, Precision Controls (Thailand) Ltd., and they had undertaken to install and operate a Kipp & Zonen ACFR factory-standard automatic calibration facility for pyranometers. Challenge number one was that they were in the process of moving into the first building to be occupied in a very nice new business park, and it was still under construction.

Luckily, some of the Precision Controls (PC) people had visited Delft in April and seen the calibration equipment and understood the preparations needed. The shipment is rather large, two full-size pallets and very heavy, and they could not receive it until the third week of May. They also had to prepare a suitable calibration laboratory and install a 24/7 VPN connection to exchange data with the calibration server at the factory – and there was no fibre-optic cable into the whole technology park.

PV Plant Performance Ratios during Design and Installation

[fa icon="calendar'] 4-jul-2017 16:31:21 / by Jan-Willem Sips posted in pv, performance ration, performance ratio, pv performance

[fa icon="comment"] 0 Comments

I used to train installers of (mostly residential) PV systems, and tell them that half of the quality of a PV system is in good materials and design, and the other half is in proper installation. For utility solar systems there is even a “third half” (if there is such a thing); maintenance!

A good measure of the quality of a PV plant is the Performance Ratio: it separates “the good, the bad and the ugly” solar systems from each other. Find out more in our whitepaper: 6 key influences that determine PV performance ratios.
