Supported by EKO Instruments

EKO Instruments Co., Ltd. supported Kogakuin University at the Bridgestone World Solar Challenge 2019 (BWSC 2019) in Australia, held from the 13^th to the 20^th of October 2019, with a set of EKO designed and manufactured Pyranometers.

The Bridgestone World Solar Car Challenge (BWSC) is one of the toughest races in the world. Held every two years since 1987, the 2019 event saw 44 teams from 21 countries attempt to travel 3,000km (about 1900 miles) in intense conditions across Australia, from Darwin to Adelaide, in solar-powered vehicles.

Despite crashing twice due to adverse weather conditions and strong winds, the Kogakuin University team finished in 5^th and won the ‘CSIRO Technical Innovation Award’ for their unique hydro-pneumatic suspension system; the first time that such technology has been applied to solar-powered vehicles.

Why does a Solar Powered Car need Pyranometers?

A solar-powered car has only one source of power, the sun. To stand a chance of finishing, let alone winning, the BWSC teams must optimise energy management in their vehicles. In other words, they need to know precisely how much energy they are generating and using during the race. Measuring solar radiation and checking weather conditions via satellite data helps them to calculate how much energy will be generated.

At BWSC 2019 the Kogakuin University Solar Team used two EKO pyranometers; one installed on the accompanying ‘Scout car’ driving 200 to 300km ahead of the race car, and another on the ‘Strategy car’ driving close behind.

It’s true that two of anything is almost always better than one. From double glazed windows, through 2-ply tissues, and ‘Buy One Get One Free’ special offers; it’s hard to argue against the logic that two scoops of ice-cream are better than one.

Pyranometers, instruments used to measure solar irradiance, are no exception. In fact, when it comes to ‘Secondary-Standard Pyranometers’, known more colloquially as Class ‘A’ (per ISO standards), the general consensus has been that they should be ‘double domed’ as standard. This is based on the idea that an additional dome reduces thermal offset and increases radiation shielding.

But ‘almost always’ doesn’t mean ‘always’ and at EKO, we developed the conviction that more of something doesn’t automatically mean ‘better’; that a single dome pyranometer could do everything a double-domed pyranometer could do, with no negative impact on performance or loss of accuracy.

With the MS-80, the only sensor to achieve the best performance rating on zero offset among Class ‘A’ pyranometers, we’ve proved it.

The innovative, and patented, single-dome design of the MS-80 includes a Quartz diffusor, and isolated thermopile detector; the core of the pyranometer that defines most of its capabilities and characteristics, features that deliver several advantages over its double-domed competitors:

• A thermopile that is 10x faster, with rapid response times from the sensor
• A detector that is isolated inside the body, achieving the lowest offset A
• Offset B is also improved with the isolated detector better able to adapt to ambient temperature changes
• With a single dome, the optics are designed to provide true cosine response and lat spectral responsivity in the range 285nm – 3000nm
• Better long-term stability. The detector is hermetically sealed, which makes it immune to humidity changes and the impact of UV
• Temperature dependency optimised for each detector
• Non-linearity effect
• Each unit contains a drying agent inside the sealed sensor body that doesn’t need to be replaced, ever!
• Lower cost & less maintenance

The MS-80 is unique, a single dome sensor based on an isolated thermopile detector and Quartz diffusor; immune to offsets, compliant to the "Fast response" and "Spectrally flat" sub-categories under ISO 9060:2018 Class A. With optional value-added functions such as a ventilator, heater and different industrial interfaces, the MS-80 keeps working in any condition; dew, frost, snow, and dust aren’t a problem.

Variants including the MS-80A; an MS-80 with a built-in 4-20mA converter, and the MS-80M, with a built-in MODBUS converter, are compatible with industrial output standards. Due to the ultra-low temperature dependency and exceptional non-linearity characteristics, these variants guarantee optimal sensor performance under any environmental condition.

MS-80 pyranometers, like all EKO products, are manufactured in a consistent way with strict quality inspection and performance evaluation. For each sensor, the directional response and temperature dependency are measured and validated through a measurement report that comes with the sensor. Our unique calibration process is compliant to international standards defined by ISO/IEC17025/9847.

Next time you have to choose between 1 scoop of ice-cream OR 2, get the ice-cream cake instead. When it comes to single OR double domed pyranometers, choose Quality over Quantity, choose the MS-80.

Why is it Gaining Momentum?

Bifacial Photovoltaic (PV) modules have nothing to do with face creams, skincare, or tanning; and everything to do with the future of solar power generation.

‘Bifacial PV’ modules are a type of solar panel designed to receive solar irradiance front and rear, generating power on both sides and, in a nutshell, that allows for new possibilities in solar power; alternatives to the conventional south orientation and latitude-based tilt optimisation of traditional projects.

New possibilities mean greater flexibility, greater power generation potential, and a great deal more excitement.

Indeed, the 2 Vs. 1-way power generation potential of Bifacial PV modules is helping to drive growth in PV power generation projects, despite reduced government incentives globally, with the ‘International Technology Roadmap for Photovoltaics’ predicting that Bifacial PV modules will represent 35% of the PV module market share by 2028.

This all sounds great, and indeed, with Bifacial PV you would naturally expect increases in yield and performance, however, there are uncertainties as to how much actual yield can be expected at each location. Like traditional PV projects, modelled yields and returns are needed to determine project scope, design, and to help secure financing.

That being the case, researchers around the world are working to define just how much additional power these new modules will make at different sites, under different sky conditions, and in different string configurations.

Performance monitoring of PV sites has for years required continuous measurements of the solar broadband irradiance, with instruments deployed in Global Horizontal Irradiance (GHI) and Plane of Array (POA) irradiance orientations. Now the added parameter of upward or reflected irradiance (RI) must be monitored too.

Enter EKO Instruments!

EKO Albedometers like the MS-80 are capable of being mounted in a traditional albedo measurement configuration, one sensor measuring the downward irradiance and another measuring upward irradiance; both levelled horizontally with the surface. And EKO is unique in the PV industry for its complete product line of research-grade equipment.

With EKO, researchers can source the sensors they need to study the true performance of bifacial PV modules. Get in touch to find out more.

The old-style EKO Newsletter is ending and we are replacing it with two new publications:

Finding EKO online used to be a bit of a challenge. We have a website of course, but we haven’t been the most ‘digitally’ minded; ironic for a company that has been at the forefront of scientific instrumentation in meteorological and environmental analysis for over 90 years.

Though we still take pride in building direct relationships with our customers and partners, the fact is that our world has gotten a lot bigger over the years. In 2007, we established EKO Instruments USA Inc., and in April 2008 EKO Instruments Europe B.V. was launched in The Netherlands. Since then we’ve expanded into India, China, and South America too. EKO sensors are now deployed around the world; from solar parks near Tokyo to mountain tops 2,367m above sea level, and the cold extremes of the Antarctic.

Though we don’t anticipate too many enquiries from the South Pole, its clear that we need to make it easier to get in touch with EKO wherever you are.

That’s why we are pleased to announce the re-vamp and re-launch of EKO on social, across LinkedIn, Facebook, and YouTube; with a new look, regular updates, and all new content.

LinkedIn has become our main English language channel, with Facebook now available in Japanese. On YouTube meanwhile, you will soon see a whole slew of videos, from product demo’s, and interviews, to fun little tests, and insights into life at EKO.

Get in touch on social, and follow us to find out more about the latest developments in #SolarPV, #RenewableEnergy, and much much more.
