CARPORT Kit for 1 car

This kit turns the parking space into a small power plant: a metal structure standing on its own foundation, with photovoltaic panels instead of an ordinary roof. The car stays sheltered from rain, hail and sun, and the panels above produce current that goes straight into the house. Unlike the plain structure, here you get the complete package - structure, panels, the inverter that converts the panels' current into current usable at the socket, the smart meter and the cables.

There are 9 panels of 430 W, that is 3.87 kWp installed, connected to a 4 kW single-phase inverter - a typical size for a house with a single-phase connection. The panels are bifacial, so they gain a little extra from the light reflected by the surface under the carport, and they lose little to heat: the coefficient of -0.26 %/°C means a smaller drop on scorching summer days than with classic panels. They withstand 5400 Pa of snow and 2400 Pa of wind and work between -40 and +85 °C. The inverter has no fan, so it makes no noise, it has an IP65 enclosure and is monitored from the phone over a WLAN connection, while the two MPPT inputs allow the panels to be split into two strings, useful if part of the carport is shaded at certain hours. The 100 A smart meter is fitted at the connection point, measures how much you consume and how much you feed into the grid and allows export limitation when the operator requires it.

Who it suits

Suitable for a house with a single-phase connection and a free parking space, that wants a ready-sized system under 4 kW, for self-consumption and, possibly, for charging an electric car.

Terms explained

• kWp: The maximum power the panels deliver under ideal sun conditions; here, 3.87 kWp means the total size of the system.
• MPPT: The circuit in the inverter that permanently looks for the combination of voltage and current at which the panels deliver the most; two such circuits allow two groups of panels to be managed separately.
• Bifacial panel: A panel that also produces on the back side, using the light reflected by the surface underneath - at a carport, by the parking paving.

Technical specifications

Recommended applications

• Residential parking with its own photovoltaic production
• Self-consumption and EV charging from the energy surplus
• Company premises with a single-phase connection
• Prosumer installation under 4 kW, without occupying the house roof

Technical details

Specifications confirmed from the manufacturer's datasheet

A complete on-grid assembly mounted on a carport: self-supporting WSC structure for one vehicle, made of anti-corrosion treated steel, with the roof tilted at about 10 degrees and oriented south, equipped with 9 Canadian Solar CS6R-430H-AG HiHero modules of 430 W, resulting in 3.87 kWp installed. Product code XFS_WSC001.2.

The HiHero modules use heterojunction technology (HJT) on an n-type wafer, with 108 cells, bifacial glass-glass construction and an anodised aluminium frame. Dimensions 1722 x 1134 x 30 mm, weight 23 kg, module efficiency around 22%. Electrical parameters at STC: Voc 40.1 V, Isc 13.38 A, Vmp 33.8 V, Imp 12.76 A. The power temperature coefficient of -0.26 %/°C is markedly better than on usual PERC modules, which means smaller losses during the summer; on a carport, where ventilation behind the modules is good but exposure is total, the advantage is seen directly in the output. Load resistance: 5400 Pa snow and 2400 Pa wind, operating range -40...+85°C. Being bifacial modules, an additional gain can be obtained from the radiation reflected by the surface under the carport.

The conversion is provided by the single-phase Huawei SUN2000-4KTL-L1 inverter of 4 kW, with 2 independent MPPT trackers, maximum input voltage 600 V, maximum efficiency 98.4% and European efficiency 97.5%. The enclosure is IP65 with natural cooling, without a fan, dimensions 365 x 365 x 156 mm and weight 12 kg, operating range -25...+60°C. RS485 and WLAN communication for monitoring. The two MPPTs allow the array to be split into two strings, useful if part of the carport is partially shaded during certain periods of the day.

The kit includes the Huawei DDSU666-H 100 A smart meter, fitted at the connection point for measuring consumption and injected energy and for the export limitation function, plus 30 m of 4 mm red/black solar cable. The panel mounting structure is included.
