With IECRE approval achieved, the ArcVera team is excited to be able to increase those numbers and solidify itself even more as a PPT services leader in the industry. ArcVera also represents the United States on the IEC committee, which develops standards for wind turbine power performance testing (61400-12-1), nacelle lidar power performance testing (61400-50-3), and energy assessments (61400-15).



Solar Heat European Market 2019 Report


The European solar heat market has grown by 2.5% in installed capacity in 2019 and 3.4% on year-on-year sales. The sector has been growing its cumulative capacity continuously for over 4 decades and there are over 10 million solar thermal systems installed in Europe today.

Growth in total installed capacity

At the end of 2019, the total solar thermal installed capacity has reached 37 GWth, corresponding to a total area of 52.9 million square meters. Among the top ten European markets, the highest increase in cumulative capacity was observed in Denmark and Poland, with around 10% growth.

Growth in annual sales

The annual sales have increased again in 2019 by 3.4%, reaching 1.59 GWth, corresponding to over 2.27 million m2 of solar thermal collectors installed. This growth follows a growth of 2.4% in 2018. From the top European markets, those showing the largest growth were Denmark, with an increase of 174% – totalling 137 MWth(196 000 m2) – and the Netherlands, with a 44% increase (35 MWth / 50 000 m2). Among Southern European countries, the main market, Greece, has grown 10%, corresponding to annual sales of 253 MWth (361 000 m2).

Germany, the largest European market

The largest European market remains the German one, which experienced growth of 0.5% in installed capacity and a decrease of 11% in annual sales. This market has seen mainly an impact on combi-systems (used for both space and water heating). Though preliminary 2020 data indicates a substantial growth in this market, reverting the previous trend.

More jobs, less CO2 emissions

In terms of economic impact, the solar heating and cooling market has achieved an increased turnover of 1.9 billion Euros in 2019, representing up to 20 000 jobs. The market also brought substantial environmental benefits, as the 26 TWhth energy generated annually represents the equivalent of 7 MtCO2 savings per year.

Among the top 5 most deployed renewables, both in Europe and globally

Solar thermal for heating and cooling is one of the main renewable energy sources (RES) in Europe and globally, in terms of cumulated capacity and annual energy generation. The total installed capacity globally amounted to 442 GWth in 2018, corresponding to an energy generation of 363 TWhth. In Europe, there are 37 GWth of cumulative capacity for solar thermal energy, generating 26 TWhth in 2018. This makes it, together with bioenergy, hydro energy, wind and solar photovoltaics, the main renewable energy solutions in the market.

One of the most competitive renewable energy sources

Solar thermal provides energy at the lowest costs among all RES. It can compete with direct electrical heating solutions and some solutions can even compete with gas, even without considering costs associated to externalities from those sources, such as CO2 emissions or other.

Deutsche WindGuard unlocks complex wind sites with ZX Lidars

With the introduction of a solution to allow the standalone use of wind lidar ZX 300 in complex terrain, Deutsche WindGuard has made a successful start to 2021. The new “ZX Complex Flow Solver” (ZX CFS) is the result of a joint development with the leading computational wind engineering organization ZephyScience, supported by lidar OEM ZX Lidars. Fully based on computational fluid dynamics (CFD), ZX CFS identifies, quantifies and resolves the relative differences between lidar and cup anemometer measurements witnessed in complex terrain.

“Deutsche WindGuard has been supporting lidar applications since 2004,” says Johannes Cordes, Wind and Data Analyst at Deutsche WindGuard’s Wind Resource Assessment team. “While stand-alone lidar measurements in flat terrain have already had a high acceptance in the past, we see the particular challenges of stand-alone measurements in complex terrain well addressed and appropriately treated with the ZX CFS application. The design and structure of this service provides the best available solution for bankable wind resource and energy yield assessment based on stand-alone lidar in complex terrain.”

In complex, non-benign terrain, the assumption of homogeneous flow conditions within the measurement volume introduces differences between lidar and cup anemometer. The Complex Flow Solver algorithm developed by Deutsche WindGuard is optimized for ZX Lidars’ wind field reconstruction. Incorporating results from a high-resolution CFD model, it derives a set of conversion factors. Applied to the volume-based wind data from Continuous Wave Lidar ZX 300, which samples 50 measurements points per second, these conversion factors produce single point measurements equivalent to those of a cup anemometer installed at the same location. 

ZX CFS even provides guidance on where to install the lidar initially to achieve the lowest possible uncertainties. Cloud computing delivers fast, transparent and accurate results. 

Uncertainties associated to inhomogeneous flow conditions within the measurement volume according to IEC 61400-12-1 Ed. 2 (2017) L.4.5 can thus be reduced significantly. This widens the usability of ZX 300 wind lidar standalone deployments for wind resource assessments in complex terrain with no additional onsite met mast.
