The Future of Solar Power in India

The Jawaharlal Nehru National Solar Mission (JNNSM), an initiative of the Government of India and Indian State Governments, has targeted generating 100 GW of the country’s national power through solar sources by the year 2022.

Re-calibration: a matter of good maintenance practice

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!

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.

A busy week in Bangkok

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.
