Design work for a project under discussion. The figures below come from our own layout and calculations. They are design values, not readings taken from a running installation.

The 3D example shows three tables serving one 30 kW pump.
Single- and double-row arrangement: 15 + 30 + 30 modules, with five independent strings of 15 modules. Site cables run underground; no above-ground cable trays or dedicated tray supports are included. Transparent ground reveals the schematic cable routes. Burial depth, foundations and equipment positions remain subject to detailed installation design.
Single- and double-row ST5 tables support the required array sizes. A 30-module table carries two separate 15-module strings. Each system retains its own DC combiner and control cabinet.
| Pump rating | Quantity | Tables / system | Positions / system |
|---|---|---|---|
| 22 kW | 1 | 2 | 60 |
| 30 kW | 2 | 3 | 75 |
| 37 kW | 2 | 3 | 90 |
| Project total | 5 systems | 14 tables | 390 |
60 modules: 30 + 30. 75 modules: 15 + 30 + 30. 90 modules: 30 + 30 + 30. With 15 modules per string, the 60-, 75- and 90-module systems have four, five and six strings respectively. The project totals 2 single-row tables plus 12 double-row tables: 14 tables, 26 strings and 390 modules / 253.50 kWp at 650 W. The 3D shows the 75-module example.
The maintained selection permits operation to resume the next day. Water-level, temperature and fault protection take priority.
Protection takes priority. Low water, a full tank, faults or overtemperature stop the pump as defined by the control logic. The design uses a 50°C actual upper air-temperature limit at the drive inlet, a red alarm and manual reset after cooling. Continuous operation at 55°C ambient is not specified.
Standard sections and matched module clamps.
Manufacturing drawings define dimensions, holes and assembly details.
Rails and inclined beams follow the supplier drawing. Posts and diagonals: C60 × 40 × 10 × 1.8 mm.
The restored arrangement shows separate front- and rear-leg bases: 12 foundations per table, or 36 in the three-table example. Base components and anchors are schematic; final details follow the confirmed supplier drawings.
Rear X bracing at both end bays. Coating specification and matched module-clamp details follow the final supplier documentation.
The original 10 September drawing uses separate front and rear foundations and marks a 200 mm buried portion. It does not specify block length, width or total height. GL 500 mm refers to module clearance above ground, not the concrete block width. The displayed block is schematic; foundation dimensions require a supplier detail.
Positive and negative cables paired by string
75-module example: five string inputs, one output
PV/grid transfer and motor drive
Separate motor cable and protective earth
Array leads descend to underground routes towards the equipment room. Above-ground cable trays, tray lids, band clamps and dedicated tray supports are excluded. Burial depth, cable suitability and any required ducts will be defined with the site installation details.
The common earth strip is fixed along the outside faces of the end-side metal posts. Five downleads in the 75-module example connect directly to the strip through crimp lugs. The strip, fixings and basic bonding materials are included in the proposed scope; the site earth electrode and site works are separate. Strip section, joints and any restraint between tables remain installation details.
The customer has confirmed a local room for the DC combiner and pump control cabinet. The open room envelope is illustrative. Building dimensions, ventilation and cable-entry details will be coordinated during detailed design.
Engineering documents will be uploaded as their revised versions are completed.
The current 3D proposal is provided for arrangement review and confirmation.
The ST5 structural load report is pending. It will assess the mounting members, connections, anchors and foundations against the confirmed site conditions and design criteria.
Structural assessment must cover the single- and double-row ST5 mounting arrangement.
Connection forces, restraint assumptions and deformation limits will be checked in the structural report.
Final verification will use the confirmed ground level, soil conditions, reinforcement and foundation details.
The completed report will be uploaded here after engineering review.
Refer to the clauses and applicability conditions actually assessed in the report.
Design references for DC wiring, protection, transfer and earthing.
Consider temperature, grouping derating, voltage drop and protective conductors.
Conformity requires the applicable product and assembly verification records.
Every pumping job starts from the same two numbers: how much water, and how far up. Work those out first and the rest of the system follows.
Scope. We supply the equipment package: modules, mounting, drive cabinet, cabling, protection and the shipping documents, FOB China through audited partner factories. Drilling, pipework, civil foundations and site installation are not in our scope and stay with the local contractor.
