Casing for irradiance sensors
The present invention is in the field of a sensor for measuring light, in particular of measuring solar irradiance on a planar surface, more in particular a sensor designed to measure the solar radiation flux denstty {either spectrally resolved or integrated) such as from the hemisphere above within a limited wavelength range, a casing for such a sensor, a sensor comprising said casing, and a PV-module or PV-system comprising said sensor.
A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface. It is designed to measure the solar radiation flux density (W/m?) from the hemisphere above. A typical pyranometer does not require any power to operate. Typically a limited wavelength of operation is used, such as in a range 300 nm (UV-light) to 3000 nm (infrared).
The name pyranometer stems from the Greek. Typically irradiance measurements with different degrees of spectral sensitivity will be obtained. As the earth rotates and the pyranometer is typically fixed, the sunlight angle of incidence may vary. The pyranometer may be adapted to correct for such variations. Typically thermopile technology and silicon semiconductor technology may be used to construct a pyranometer (ISO 9060). A thermopile pyranometer typically has a connector with a connection cable, a pyranometer under at least one glass domes, a black detector surface, a sun screen, a heat sink, a desiccant indicator, and positioning means.
A thermopile pyranometer is adapted to calculate irradiation from a differential measure between the temperature of the black sectors being present therein, exposed to the sun, and the temperature of the white sectors, which white sectors are not exposed to the sun. Such makes these sensors sensitive to temperature influences, such as due to heating of the sensor itself. The thermopile generates a small voltage in the order of 10 pV (microvolts) per W/m. The pyranometer may also be a photovoltaic pyranometer, such as a silicon photodiode, making use of the photoelectric effect to convert light into an electric current. The wavelength range of such photodiodes is somewhat more limited, such as to 400 nm and 1100 nm. The conversion is sensitive to temperature changes. The raise in current produced by the change in temperature may be £0,1% per degree K. The PV pyranometer typically comprises a housing, the photodiode, an output circuit, signal conditioning electronics, and optical elements such as a diffuser or optical filters. The current generated by the photodiode is considered to be directly proportional to irradiance. It may function as a reference cell. So pyranometers may be more or less sensitive to light, or a part of the spectrum thereof, apart from inherent sensitivity issues such as diffraction light.
A pyranometer may have additional sensors, such as for temperature, wind speed, etc. A pyranometer typically requires calibration before and during use, e.g. using IEC 60904-4 or IEC 60904-2.
The applicant recently developed an improved albedometer, which albedometer is specifically suited for use as a pyranometer. It is adapted to resolve light, which may be direct sun light or reflected light. In this respect reference can be made to patent application
WO2021/162544 (Al), which document and its content is incorporated by reference.
It is noted that solar cell outputs show nontrivial variation with changing spectra. This may especially be the case for multi-junction solar cells, due to their increased spectrum sensitivity from current mismatch effects. Therefore, information about incoming solar spectrum is desired in order to accurately determine the yield of solar cells or modules and to optimize said yield.
The present invention therefore relates to an improved pyranometer, which solves one or more of the above problems and drawbacks of the prior art, providing reliable results, without jeopardizing functionality and advantages.
It is an object of the invention to overcome one or more limitations of the prior art and provides an improved pyranometer, which are less sensitive to changes in temperature, are more accurate, wherein a chance of overheating is reduced, and which provide passive cooling.
Thereto a pyranometer is provided, comprising at least one solar irradiance sensor, such as the albedometer of the present inventors, and a casing, wherein the casing comprises at least one fin extending outwards, in particular at least four fins, wherein the at least four fins are substantially evenly divided over a circumference of the casing. Fins are defined as surfaces that extend from an object, or part of said object, in this case the casing, which increase the rate of heat transfer to or from the environment by increasing convection. Likewise inverted fins (cavities) may be considered, which inverted fins are considered to be covered by the scope of the present claims.
Open cavities are defined as the regions formed between adjacent fins. These cavities can be utilized to extract heat from the present casing. Hence the term fin is considered to relate to the extending surface, or likewise to the open cavity, or a combination thereof.
The present pyranometer limits heating thereof. For instance, when illuminated directly from the top (90 °tilt) for 15 minutes with 800 W/m? the present pyranometer shows 2 °C less heating compared to a pyranometer with a casing without fins. When illuminated directly under an angle (60 °tilt) for 15 minutes with 800 W/m? the present pyranometer shows 5 °C less heating compared to a pyranometer with a casing without fins.
In a second aspect the present invention relates to a casing for the present pyranometer, in particular wherein the casing is partially or fully 3D-printed, or made by using a mould, or made by milling. The casing may equally well be used for other sensors or the like, such as a spectroradiometer.
In a third aspect the present invention relates to a sensor requiring thermal management comprising a casing according to the invention, and the sensor, the casing protecting the sensor from heating, in particular from overheating.
In a fourth aspect the present invention relates to a product comprising the present pyranometer, wherein the product is selected from a PV-module, a PV-system, a meteorological sensor, a climatological sensor, a building sensor, and a photovoltaic power station sensor. The product complies to IEC 61724-1:2017. The product in particular relates to a pyranometer which is installed in-plane with the product.
