Solar panels for homes, rooftops and PV systems
This catalog contains Veichi VCS solar panels: 36 active SKUs from 390 to 630 W. There are standard monocrystalline modules and bifacial panels. They are used for rooftop PV, ground-mounted arrays and hybrid backup systems where a hybrid inverter and solar battery are part of the setup.
We do not size panels by wattage alone. The mounting place, string Voc, MPPT input range and available roof area come first. 390-430 W modules help when the roof has chimneys, skylights or narrow zones. 575-630 W modules are better when the goal is to collect more kW with fewer panels.
How to choose solar panels
Start with the inverter. Check the MPPT range and maximum allowed Voc in the datasheet. Then calculate the string: panel open-circuit voltage multiplied by the number of modules, with a cold-weather margin. Without that check, winter voltage can exceed the inverter limit.
The second step is roof area. A 5 kW PV array takes roughly 8 panels at 630 W or 13 panels at 390 W. It is quick math, but it shows whether the roof is large enough. If the surface behind the module is dark and absorbs light, a bifacial panel will not add much. On a ground frame, white membrane or flat roof it starts to make sense.
| Model | Power and efficiency | Voc / Vmp | Best fit |
|---|---|---|---|
| Veichi VCS-108H-390-P | 390 W, 19.97% | 36.85 / 30.64 V | Small roof, complex geometry, short strings |
| Veichi VCS-108H-405-D | 405 W, bifacial, 20.74% | 38.07 / 31.40 V | Flat roof or ground frame with rear-side reflection |
| Veichi VCS-156H-575-P | 575 W, 20.57% | 53.44 / 44.20 V | Fewer modules on the same rooftop area |
| Veichi VCS-156H-610-D | 610 W, bifacial, 21.82% | 53.98 / 44.78 V | Ground-mounted PV or a roof with mounting reserve |
| Veichi VCS-156H-630-D | 630 W, bifacial, 22.54% | 54.46 / 45.26 V | Maximum wattage per module in the VCS line |
Manufacturers of solar panels
This section currently has one brand with a real active catalog and orders: Veichi. The VCS line covers 390-630 W, mono and bifacial modules. We do not add brands that are absent from the active catalog. It is better to show what can actually be supplied.
Solar panels by specifications
If you select by wattage, open 400 W, 500 W or 600 W. Exact filters are available for 400W, 600W and 630W. By module type, use standard monocrystalline or bifacial. For ready intent pages, see solar panels for home and solar panels for roof.
Warranty and support
Before ordering, send three things: inverter model, roof photo or dimensions, and target PV power. We will size the number of panels, check string voltage and tell you whether a battery is needed. We supply with VAT invoice, delivery across Ukraine and engineering selection for the actual site. If the task is irrigation or a well rather than rooftop PV, check solar pump inverters.
