摘要： A method of removing a plurality of portions of a black layer of an electrical conduit for a photovoltaic cell is disclosed. The method includes providing a mandrel having the electrical conduit electroformed in the mandrel. The electrical conduit is formed in a preformed pattern on an outer surface of the mandrel. The electrical conduit has the black layer with a black layer thickness on a side opposite of the outer surface of the mandrel. A beam of a laser is controlled toward the black layer of the electrical conduit. The beam is characterized by laser parameters. The beam of the laser removes the plurality of portions of the black layer on the electrical conduit. Each removed portion of the plurality of portions of the black layer has a thickness equal to the black layer thickness, and a portion area of 5 mm2 to 20 mm2.

摘要： Systems and methods integrate advanced solar tracker, battery, inverter, and software technologies to improve performance, plant output, and costs. The systems may incorporate an advanced vanadium flow battery (VFB) that is DC-voltage (DV)-coupled to photovoltaic (PV) arrays for high, round-trip efficiency. The systems incorporate a DC architecture that optimizes performance for commercial, industrial, agricultural, and utility applications. A distributed direct current (DC) power system includes a centralized, single-stage inverter; PV arrays; maximum power point tracking (MPPT) converters coupled between the PV arrays and the centralized, single-stage inverter; batteries; and DC-DC battery converters (DCBCs) coupled to the batteries. The MPPT converters maximize solar power production by the PV arrays and minimize mismatch between the PV arrays. The DCBCs manage charge and discharge of the batteries, enable the interconnection of the PV arrays and the batteries, and supply a constant medium voltage to the central inverter.

摘要： A power conversion circuit is used in a solar array suitable for, e.g., roadside adjacent installation. The power conversion circuit includes an inverter with a first stage electrically coupled to one or more solar panels. A third stage of the circuit has a DC to AC converter that provides less than a 50 VAC load voltage to a load, and a second stage that is coupled between the first and third stages and provides an isolated electrical power coupling therebetween. A sync interface communicatively couples a controller to other controllers dedicated to one or more other respective inverters of the solar array via a sync signal. The controllers synchronize the third stages of the inverters via the sync signal. The third stages of the inverters are coupled in series to provide a load output voltage.

摘要： The invention relates to a movable shingle arrangement of rectangular strip modules comprising a covering of solar cells on carrier materials that differ according to choice, such that the shingle arrangement can be arranged in such a way as to allow it to be unfolded, extended or set up as a canopy. The problem addressed is that of providing a novel connecting structure for a movable shingle arrangement, wherein supporting structures for mounting and displacement purposes are formed on an arranged system of rails that can be extended or swung out. The shingle arrangement (1) according to the invention consists of coupled rectangular strip modules (2), which are covered with crystalline and thin-layer solar cells (3) and overlap one another. A system of rails (6, 21) is arranged along at least two outer edges (18). Formed under the system of rails (6, 21) are supporting structures suitable for mounting and guiding purposes. Arranged on the rectangular strip modules (2) is/are one, two or more rows of solar cells (3), which are arranged next to one another and are interconnected in such a way that there is a maximum possible surface coverage with active photovoltaic solar-cell material. In the extended state, the rectangular strip modules (2) overlap like shingles. Along at least one long side (19) of the rectangular strip module (2), a defined perforated structure made up of depressions or through-openings (9) is arranged in such a way that elevations, balls or pins (10) of an adjacently arranged rectangular strip module (2) engage in this perforated structure, and so a mechanically stable connection is produced. The rectangular strip modules (2) are coupled to one another by means of a cable pull or a system of rails (5) in such a way that they can be extended or retracted manually or automatically. In the pulled-in or retracted state, the rectangular strip modules (2) arranged longitudinally or transversely alongside one another lie one above the other in a stack or one alongside the other in a shingle box (23). The rectangular strip modules (2) may be set up for example in an upwardly sloping manner by means of a system of double rails, in order to make an optimum energy yield possible.

摘要： A power converter box and at least one junction box are integrated on a backplane of the photovoltaic module as a whole, and there is a cable for connecting the power converter and the junction box. In this case, relative to the conventional technology in which a junction box is independent of a power converter, a length of a cable used when the junction box and the power converter box are taken as a whole is shorter than a length of a cable used in the conventional technology. In this case, compared with the conventional technology in which a cable is connected to an independently placed power converter, the power converter only needs to establish a connection relationship by using a solder ribbon, a circuit board cable, and the like with low costs, so that production costs are low.

摘要： An earth-mount utility-scale solar photovoltaic array has modules supported on the ground to establish an earth orientation of the modules. These modules sit in a closely adjacent arrangement or an abutting arrangement of module rows. One general aspect includes a utility-scale group of modules that contains greater than 800 conterminous PV modules in which more than 80% of the modules are earth-mounted. Implementations may include the array having one or more of the following features: eight groups of modules; no connection to an inverter with an ac output; no stowing functionality or extreme dampening functionality. Implementations of the described techniques may include solar arrays and related methods.

摘要： An improved solar power generation system, having at least one solar-array module. The solar cells in a solar-array module are interconnected in a crisscross matrix network configuration. The solar cells are a pre-sorted by the class of tolerance level of output power, such that the solar cells in each of the rows of solar cells are arranged in a steadily ascending (or steadily descending) order of the maximum power values that the solar cells are capable to provide, wherein the maximum power value of a solar cell in a particular row is higher or equal to the maximum power values of the previous (next, for steadily descending order) solar cells in the same row.
