Description

Fixed PV mounting system
The invention refers to bolt-assembled mounting bases which are used as surface mount for PV modules arranged in vertical double row (portrait) or horizontal triple row (landscape).
Electricity production from PV modules is widely applied throughout the world.
Mounting bases are used as surface mount for modules in projects of energy production from modules. These bases are usually constructions made of galvanized steel, or aluminum, or a combination of both materials. They consist of the part of their foundation and superstructure.
This invention refers to bolt-assembled construction of modules' mounting base entirely composed of galvanized steel. The metal constructions are composed of individual parts assembled together by bolts or welds in advance. Metal parts are usually composed of the foundation and superstructure parts.
The foundation part creates the superstructure's support. It usually consists of either two or one foundation point for each superstructure's support. In the case of two support points, a hole in the ground at each point of support is usually opened; a metal support- stand is placed into the hole which is consequently filled with concrete or cementitious grout. Each such metal support-stand has a special configuration at the top in order to receive the part of the superstructure's mounting base. In the case of the one support foundation point of the superstructure, it consists of metal support-stand which either is rammed into the ground using pile-driver, or a hole is opened in the ground in advance, where the metal support-stand is placed and is finally filled with concrete or cementitious grout. The above foundation layouts are repeated at distances of 2.00 m to 4.00 m.
The present invention refers to modules' mounting base entirely made of galvanized and cold-rolled cast steel, commercially available materials. The foundation part per superstructure's support consists of a galvanized cast steel support-stand with standard cross-section which either is rammed into the ground using pile-driver, or a hole is opened in the ground in advance, where the metal support-stand is placed and is finally filled with concrete or cementitious grout. This outlet is repeated at distances of 2.00 m to 4.00 m. A metal galvanized beam of typically standard cross-section (yoke) is connected to the head of each metal support-stand through a special galvanized metal piece. Eventually, the final metal beams (purlins), on which PV modules (panels) are ultimately anchored, are placed on the yokes along the whole outlet.
The above mounting outlet, although abounds in advantages, shows disadvantages too. For example, either during the ramming phase of the metal support-stand into the ground through pile-driver, or by its placement in the hole of the ground, divergences are shown in its final position as to vertical and horizontal direction, resulting in problems with the whole construction's assembly. In addition, the metal support-stand is made of galvanized cold-rolled steel and not of galvanized cast steel. Experience has shown that the use of cold-rolled cross-sections into the ground is contraindicated due to, at its onset, self-intensive state during the extrusion and due to thin sections that make them vulnerable to corrosion - electrolysis. Finally, electrolysis - corrosion phenomena occur at the aluminum modules' of the PV panels contact points with metal purlins because of the different kinds of metal. This invention aims to create a PV panels' mounting-base that can be easily installed and eliminates all the above mentioned disadvantages of metal mounting-bases.
According to the invention, this is achieved at the above mentioned mounting system thanks to the construction of a special metal piece that connects metal support-stand and metal purlin in a way that, at the connection stage to the metal support-stand with bolts, it may have the possibility of vertical transfer; as for its connection with the metal purlin, it may have the possibility of longitudinal transfer. In particular, the connection of the metal support-stand with the special metal connecting piece is done using only four bolts, having as a result the most convenient and easy connection between them. More specifically, the special metal piece consists of two vertical strips which are spaced as much the width of the metal support-stand (standard cross-section IPE, C, etc.); whenever required, a metal strip with the PV panels' desired angle is bonded on these vertical strips thus creating the special metal piece. Besides the bonding between them, backing to external connection corners of vertical strips with an inclined strip may be added (extra additional oblique strips, additional parts of metal cross-sections, etc.), depending on the static solution.
The connection of metal support-stand (of standard cross-section IPE, C, etc.) with special metal piece is done by the two vertical parts of the special metal piece. More specifically, four holes are drilled on each side of the metal support-stand while four longitudinal (oval) holes are drilled on each of the two vertical strips respectively. In this way, the special metal piece can be moved upward or downward in relation to metal support-stand (as half the length of these longitudinal holes) from the theoretical position of their connection. This option of vertical mini-movements collects any divergences of the metal support-stand to the vertical, during its plunging or foundation in the ground by drilling a hole and then placing and concreting.
The fastening of the vertical strips to the metal support-stand is achieved by four bolts, at least as long as the total thickness of the two vertical strips along with the width of the metal support-stand, or by eight ordinary bolts. Thus, the entire connection's assembly of the special metal piece and the metal support-stands reduces construction cost and time.
The inclined strip of special metal piece that is already bonded at the two vertical rolled plates usually consists of 4-6 longitudinal holes (oval) or as needed on the basis of system's static solution. Normal holes are drilled on the metal yoke, in positions specified by the construction drawing. Metal yoke is then placed in the metal inclined plate. Because of inclined plate's longitudinal holes, metal yoke can be shifted in its longitudinal direction, upwards or downwards (as half the length of these longitudinal holes) from theoretical connection position. This option of mini-movement collects any divergences of the metal support-stand to one horizontal direction, during its plunging or foundation in the ground by drilling a hole and then placing and concreting.
Metal support-stand is made of galvanized cast steel with commercial standard cross- section (IPE, C, etc.). Besides special metal piece, metal support-stand is connected to metal yoke with an inclined metal beam strut made of standard cross-section steel (L, C, U, etc.). Parts of stainless steel or EPDM insulating material are placed at the anchor points between PV modules and metal purlins. Diagonal anti-wind connectors (of standard cross-sections L, C, etc.) are placed every two openings on each outlet that are bolt-connected to the metal yokes, for the whole construction clamping. Finally, metal support-stands are connected by a metal beam at the end of their standard cross- section (L, C, U, etc.) on clamping longitudinal bolts of the metal support-stand with the special metal piece.
The mounting system manufactured according to this invention offers a number of advantages. Having the possibility of collecting metal support-stands divergences in both vertical and horizontal divergence, the assembly of the rest mounting-base construction (yoke, purlins) is accurately and easily done. At the same time, creation of self-intensive situations in overall construction is avoided, since assembly is done by zero divergences. In case of divergences, metal support-stand dismantling and placing back in as much as possible right position is avoided. The use of four bolts to connect special metal piece with metal support-stand is very convenient, practical and reduces construction assembly time.
The use of galvanized cast steel as a support-stand ensures project's longevity and safety, and that's because the steel part in the ground is extremely resistant to constant corrosion - electrolysis distress.
The use of stainless steel pieces or EPDM material at PV modules contact points with metal purlins prevents interface between aluminum and galvanized steel and, therefore, we have no longer electrolysis - corrosion between the two materials.
The use of anti-wind connectors and beam head for metal support-stands connection ensures a compact and firm construction.
This invention is described below with an example's help and with reference to the attached figures in which:
• FIG. 1 shows an indicative intersection and the floor plan of a construction that was chosen, 20.20 m long, with PV panels arranged in a double row (portrait) (having analogous application for PV panels arranged in a triple row (landscape)) according to the present invention.
• FIG. 2 is a vertical intersection of special metal piece as well as a vertical intersection of the mounting with the connected metal yoke; and,
• FIG. 3 illustrates the special metal piece in floor plan and the two vertical strips with the inclined one that compose it in aspects.
Figure 1 shows the mounting base construction fully developed with 20.20 m indicative length. In this example, a distance of 3.03m between metal support-stands - that their cross-section is usually one of the commercial cross-sections C, Z, IPE, etc. - was chosen which are shown rammed in the ground. Metal yokes with cross-section of C, Z, U, etc. type (2) are connected with metal support-stands through special metal piece (3) which is shown in more detail in figures 2 and 3. In addition, the metal beam strut (4) of commercial standard cross-section C, U, etc. connects metal support-stand (1) with metal yoke (2) additionally. Metal support-stands (1) are connected by the metal beam head (5) of commercial standard cross-section C, U, etc. so as their connection to the longitudinal direction of construction may be achieved. The existence of diagonal metal anti-wind connectors (6) of commercial standard cross-section C, U, etc. every two openings, which are connected with the metal yokes (2), creates a very compact and firm construction frame. Four metal purlins (7) of commercial standard cross-section C, U, etc. are placed along the construction formed in this way, bolt-connected to metal yokes, on which PV panels (8) are then placed. The position of the metal purlins (7) along the metal yoke (2) as well as drilling holes along the metal purlins (7) for direct bolt-connection with PV panel (8) (with the pre-existence of EPDM insulating material or stainless piece between the contact points), each time depends on the size and layout (portrait or landscape) of the PV panel (8). Additionally, in the slots between PV panels (8), in the longitudinal direction of the construction (this slot is usually 2 cm), there is holes anticipation for the reception of special commercial fasteners (clamps) in case of choosing to connect PV panels (8) to metal purlins (7) by these fasteners (clamps) and not directly connecting the aluminum module of PV panels (8) by metal purlins (8). Metal purlins (8) may protrude from the outside metal yokes (2) in the longitudinal construction sense and in length each time determined by the static study solution of each construction.
Figure 2 illustrates, according to the invention, in more detail all bolt connections of the metal support-stand (1) with the special metal piece (3) showing the two of the four long connection bolts (9), the connection of metal strut (4) with the metal support-stand (1) and the metal yoke (2), the connection of the special metal piece (3) with the metal yoke (2), the connections of the metal purlins (7) with the metal yoke (2), the connection of the beam head metal element (5) with the long bolt (9) and the position either of the EPDM insulating material, or of the stainless metal piece (10) between metal purlins (7) and PV panels (8).
Figure 3 illustrates, according to the invention, analytically the layout of the special metal piece (3) consisting of two vertical strips (11), (12) and an inclined strip (13) (the panels' angle taken in this figure is 30 degrees). More precisely, the distance between the two vertical strips (11), (12) is in a par with the width of metal support-stand, while their lengths depend on the desired angle of PV panels (8). Each one vertical strip has four longitudinal holes (14) with the same length between them. This length determines the possibility of vertical mini-movement with respect to metal support-stand (1). There are four standard holes respectively on the metal support-stand (1) to match those of the vertical metal strips ( 1), (12). The connection of the metal support-stand (1) with the two vertical strips (11), (12) is done by four long bolts (9) which pierce vertical metal strips (11), (12) and metal support-stand (1), or by eight ordinary bolts. The inclined strip (13) is already pre-bonded on the two vertical strips (11), (12) in order all three strips to form the special metal piece (3). The width of the inclined strip (13) is in a par with the width of the metal yoke (2). The inclined strip (13) has 4-6 longitudinal holes (15) and the number depends on the results of the static solution for equal length between them. This length determines the possibility of the metal yoke's (2) mini- movement in its longitudinal direction in relation with the inclined strip (13). Metal yoke (2), respectively to these 4-6 longitudinal holes (15), has 4-6 standard holes opened in positions determined by the construction project. The connection of metal yoke (2) with the inclined strip (13) is done by standard bolts.
All metal materials used are hot dip galvanized in order to have maximum lifetime exposed to weather conditions
