Abstract
System(s) and method(s) for mounting, deploying, testing, operating, and managing a solar concentrator are provided. The innovation discloses mechanisms for evaluating the performance and quality of a solar collector via emission of modulated laser radiation upon (or near) a position of photovoltaic (PV) cells. The innovation discloses positioning two receivers at two distances from the source (e.g., solar collector or dish). These receivers are employed to collect light which can be compared to standards or other thresholds thereby diagnosing quality of the collectors. Receiver(s) includes photovoltaic (PV) module(s) for energy conversion, or module(s) for thermal energy harvesting. PV cell in PV modules can be laid out in various configurations to maximize electric current output. Moreover, a heat regulating assembly removes heat from the PV cells and other hot regions, to maintain the temperature gradient within predetermined levels.

Figure 12 shows according to some aspects of the present invention can mechanically be coupled to PV module (showing) with the embodiment of the channelizing heat collection device 8200 that extracts therefrom heat in Figure 12.Active cooling or heat transmission medium can be embodied in the fluid that passes a plurality of (Q) passages or conduit 8210 circulations, and wherein Q is positive integer.Can be in individual metals sheet (for example, Al or Cu sheet, or have arbitrary material of high thermoconductivity) machining channelizing heat collection device 8200.On the one hand, the first aperture 8240 can allow coolant fluid admission passage heat-transmission amount gatherer and the second aperture to allow described coolant fluid discharging.Aperture 8220 or 8230 allows channelizing heat collection device 8200 fastening (for example, bolt tightening or bolt) to PV module (not shown).Can there be additional fasteners 8252 so that can be attached to the PV module.It should be noted that and to put on the open surface of channelizing heat collection device 8200 to close and seal channel gatherer 8200, in order to prevent the leakage of coolant fluid covering hard thin slice (not shown); The hard thin slice of described covering can be supported by the ridge 8254 in the inner surface of channelizing heat collection device 8200.The hard thin slice of described covering can be to utilize by circulation and passes the thermoelectric material of heat of fluid results of described channelizing heat collection device to produce the extra electricity that can replenish through the electricity output of cooling PV module.Perhaps or in addition, but the attached thermoelectric device of the described hard cover sheet of thermo-contact replenishes electricity to produce.
Channelizing heat collection device 8200 is modular, is that it can mechanically be coupled to disparate PV module (for example 8180) once with results heat energy and cooling irradiated PV module.At least one advantage of the modularized design of channelizing heat collection device 8200 is that it can recycle after PV module operation end-of-life effectively and practically; For example, when the electric current of PV module service cost benefit is exported unsuccessfully, described PV module can be dismantled and new PV module can be fastened to described channelizing gatherer from described channelizing gatherer.Another advantage at least of channelizing heat collection device is can select at least in part to serve as the fluid of heat transmission medium to adapt to the specific heat load and effectively to cause the disparate PV module with different irradiance or photon flux operation to turn cold.

Figure 13 A can be the active PV element of a part of PV module 7810 or any other PV module described herein by three exemplary sights via the irradiation of the solar collection of parabolic solar collector 7100 to Figure 13 C graphic extension.In one aspect of the invention, described active PV element be one chip (for example, integrally engage), the structure of axial orientation, it comprises that the one group of N(N that is connected in series is positive integer) individual formation or unit solar cell (for example, based on the solar cell of silicon, based on the solar cell of GaAs, based on solar cell or the nano-structured solar cell of Ge).Described group of N solar cell is illustrated as piece 8325.Described solar cell produces series voltage along the axle Z8302 of described structure
Δ V wherein
CFor consisting of cell voltage.Indivedual PV batteries are with the low-voltage produce power; Most of battery output 0.5V.Therefore, for producing essence electric power, in view of available low-voltage, electric current is often higher.Yet substantial current flows can cause the power loss that showing that is associated with series resistance, because this kind power loss and I
2Proportional, wherein I is the electric current that transports by series resistance.Correspondingly, the power loss of system-level is along with high electric current and low-voltage can increase fast.The latter causes utilizing the solar energy conversion designs of the solar cell that interconnects with configured in series to increase Voltage-output.
Vertical many knot (VMJ) solar cells of structure 8325 expression exemplary.In the one side of VMJ solar cell, consist of solar cell along stacking one group N of direction of growth Z 8302, each consists of battery and have the p doped layer near the first interface of described battery and disparate battery, and have the n doped layer near the second interface, wherein said first and second interface is perpendicular to the plane of described direction of growth Z 8302.The VMJ battery on the other hand in, under typical operation conditions, 1cm
2The VMJ solar cell exportable near 25 volts because usually N-40 formation battery is connected in series.Therefore, eight VMJ solar cells that are electrically connected in series can produce near 200V.In addition, being connected in series of formation solar cell when the VMJ solar cell is not shone equably in described VMJ solar cell can cause low current condition or consist of the open loop state that solar cells cause fault when not illuminated when one or more in described VMJ solar cell, when irradiation (for example, formation solar cell) produced the battery limitation of minimum current amount usually because the electric current of the chain of the electric active element that is connected in series output.Under uneven irradiation, the output of the electric power that produces is roughly depended on and is incident on described VMJ battery or the details of the collected light on arbitrary or arbitrary active PV element roughly.Therefore, should note, will with VMJ solar cell that interconnected in series is provided or roughly the mode of the uniform irradiation of arbitrary or arbitrary active PV element (for example, film serial connection solar cell, based on the solar cell of crystal semiconductor, based on the solar cell of amorphous semiconductor, based on the solar cell of nanostructure) design solar collector.
Figure 13 A shows that the illustrative institute focused beam 8305 of oblate shape wherein covers the exemplary sight 8300 on the whole surface of PV elements 8325.Therefore, irradiation is regarded as the best.Figure 13 B present be output as suboptimum (due to the part irradiation that consists of solar cell (being expressed as rectangle) in PV active element 8325) with respect to electric power or energy exemplary sight 8330-for example, unit or the whole width that consists of solar cell shine unsuccessfully by focal area 8335.Figure 13 C be operating trouble (for example, the zero output situation) exemplary sight 8340, because the subgroup failure of the formation solar battery group in the 8345 irradiation PV active elements 8325 of focal area, and therefore electric power is output as zero (because of the place's no-voltage appearance of not irradiated formation solar cell).
Figure 14 shows the drawing 14 by the computer simulation of the distribution of the light of exemplary parabola collector 7100 collections.Described simulation (the ray trace model that for example, can comprise the optical property of reflecting material 7205) is emerging in (perpendicular to the axle of VMJ battery) and the non-homogeneous light pattern on orthogonal direction X 8407 on direction Y 8405.The specific stretch characteristics in optical focus zone is derived from the distribution of position around the focus of a plurality of reflectors that comprise solar collector (for example, solar collector 7100) (for example, reflector 7135); Described a plurality of reflector is created in stacked a plurality of, the relatively out-of-alignment image in described receiver place.Should be appreciated that, (for example, panel 7130 when the area of collecting
1To 7130
4Area) increase and when adding extra reflection mirror or reflector, the light that is distributed in the focus place can become more and more inhomogeneous.
In addition, Figure 14 presents the chart 8450 that a pair of VMJ battery 8455 of graphic extension is described the location and aimed at respect to the exemplary of the optical imagery (for the lead tone) of solar collector (for example, 100) generation; Image in chart 8450 is identical with image in chart 8400.Can be on the side of VMJ battery 8455 add one or more VMJ batteries or any or any PV active element roughly along direction Y 8405; For example, the direction that is parallel to the back timber in support frame 7130; Usually, the pattern of VMJ battery or configuration will be the layouts that the main shaft (axle that for example, is parallel to direction Y 8405) that makes the optical imagery that passes institute's focused beam has reflection symmetry.
It should be noted that in producing the solar collector of heat energy, do not affect performance by this inhomogeneities of simulation and forecast and the experimentally irradiation of observation, because heat energy is integrated in effectively in irradiation hot receiver (for example, back install coiled pipe 7830).Yet, when being positioned near the focal track (for example, point or line) of collected light when the PV battery, uneven irradiation can cause the part of PV battery relatively poor irradiation (for example, referring to Figure 13 A to Figure 13 C) and so roughly reduce the power conversion performance; For example, reduce the electric power output of one group of PV battery in the PV module.
Should be appreciated that, the solar collector that discloses in the present invention (for example, solar collector 7100) is designed to the interior space wave (for example, the change in size of various structural details) of structure of tolerant structure.In addition, the solar collector that discloses (for example, 7100) is the tolerable environmental fluctuating also, the daily temperature gradient of (i) essence for example, and it has weather conditions (for example, Nevada, USA like the desert; The Colorado; Australia is northern etc.) and some of the serious storm situations such as image height speed wind-force and hail dispose the place and can be common event.Should easily understand, environmental fluctuating can roughly affect constructional aspect, and roughly the stress of arbitrary type can make the daylight that focuses on from designed focal track or focal track skew intentionally in addition.Described fluctuation or variation make some parts displacement up or down on the short-axis direction of the brace summer of solar receiver of institute's focused light pattern usually, and displacement to the left or to the right on the long axis direction of described brace summer vertical center line.By with the PV active element (for example, VMJ solar cell, three-joint solar cell) 7820 be positioned intentionally the focus light pattern (for instance, the light pattern overlapping with the PV cell pattern) optimum position in (for example, the position that is called off the record " dessert ") locate, the PV active element can alleviate the adverse effect that is associated with this type of variation of light pattern, even because also can keep illuminated in the situation that optical focus may be shifted.
As described below, can guarantee that the light incident on the PV element roughly configures or arrange described PV element with the irrelevant layout of the fluctuation of optical focus.In one aspect of the invention, directed PV battery is (for example on receiver by as described below, the VMJ solar cell), roughly the focusing track is (for example in the output of parabolic solar collector system 7100, point, line or arc) uneven irradiation located has elasticity, because the per unit battery in the VMJ battery can make at least a portion of its lateral areas section (for example, width) illuminated; For example, referring to Figure 13 B and associated descriptions.Correspondingly, VMJ solar cell or roughly any or any PV active element will be directed in the following manner: wherein it is connected in series with the major axis (for example, Y 8405) of optical imagery and aims at.
Figure 15 A can be used for the cluster configurations of VMJ solar cell of power conversion or the example of layout in Figure 15 C graphic extension parabolic solar collector 7100.When the VMJ solar cell is mentioned in following explanation, should note and roughly the same mode to configure other alternative or extra PV active element (for example, film serial connection solar cell).Figure 15 A shows that capable three of K=2 that have of VMJ solar cell troop 8520
