In a three-phase installation of 230V between phases, can these modules and microinverters be installed without additional transformers? What accessories need to be included in the installation?

Yes, AC modules can be installed on Delta grid arrangement with 230V between phases. No additional transformer equipment is required for typical LV connections. Alongside the microinverters that are supplied as part of the PV module, installers will need to purchase Q cables, cable accessories and the Envoy-S communications gateway.​ Contact your Sales Manager to access additional installer tools to learn more about site design and balance of system requirements. In addition to the AC module, what additional components are needed to complete the installation? In addition to the AC module, installers will need to purchase Q cables, cable accessories, and the Envoy-S communications gateway.​ Contact your Sales Manager to access additional installer tools to learn more about site design and balance of system requirements.

Is the AC module compliant with RD 244 for zero injection? Can it be used for isolated installations?

No, export limiting functionality is not yet compliant with RD 244/2019. Most installations with Enphase microinverters are residential scale (below 15kW) and are easily accepted without this compliance.​

Each microinverter is a single phase device. Three-phase installations are constructed with single phase microinverters distributed across the phases. The inverter will monitor power consumption at each phase using the CTs connected to the Envoy-S communications gateway, limiting grid export to the defined level, either on a per phase or aggregate basis as required.​In three-phase installations, can you divide surpluses by phases?

How is surplus solar production controlled?

Enphase microinverters offer export control by reducing power production at each microinverter to maintain export to a defined power level—which can be zero for a zero-export site. The microinverters do not offer control of surplus power beyond export to the electricity network.​

Does my system work at night?

Sunlight must be present for the system to generate electricity. At night, your system will hibernate, and your inverter will display a blank screen.

Are SunPower solar panels better?

Not all solar systems are created equal. Of all solar panels on the market, SunPower panels convert more sunlight into electricity. This means our solar panels generate more power than conventional panels1 within the same amount of space and you’ll need fewer solar panels to produce the energy you need. You can maximise your available roof space to choose the best, unobstructed location for electricity production. You'll save more money on electricity costs over time with SunPower.

How do SunPower Performance 7 solar panels compare to standard panels?

SunPower Performance 7 solar panels are different in many ways, they offer a combination of innovative technology and superior construction not seen in standard panels. One-third cut TOPCon shingled-cell technology is used to create high-efficiency Performance 7 solar panels, resulting in better sunlight capture than standard solar panels with lower efficiency. This translates to high power and reliable energy output, reducing electricity costs for customers. Additionally, the bifacial design allows energy generation from both sides of the panel, further optimising output and enabling solar design flexibility. 

Performance 7 solar panels are built to last. Using high-quality materials, they feature a glass-glass construction that shields them from harsh weather conditions. The flexible cell interconnections enable the panel to withstand temperature fluctuations, ensuring consistent energy production over the panel's lifespan. A low annual degradation rate helps Performance 7 solar panels to maintain their high-efficiency rate over time, whilst a low-temperature coefficient, guarantees optimal solar production even in hot climates. Experienced engineering and clever panel design incorporate strong shade management, offering resilience to a variety of shading scenarios that can detrimentally impact overall energy production. Performance 7 solar panels offer dependable energy output, durability, and long-term reliability not seen in standard panels.

How do SunPower Performance 6 solar panels compare to standard panels?

SunPower Performance 6 solar panels are the predecessor of our latest generation, SunPower Performance 7 solar panels. The technology is different between generation 6 and 7, but both generations are exceptional when compared to standard panels. 

There are a variety of key technical differences between SunPower Performance 6 solar panels and standard panels, including the design and layout of the solar cells, the conductive material used, and the electrical architecture—which combine to enhance their reliability, performance and aesthetics. 

To go into a bit more technical detail, we laser cut Mono PERC cells into six strips and layer them in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows us to fit more active cell area into each panel, boosting power and efficiency. Using high-quality materials and premium encapsulants, they are built to last in harsh weather conditions. SunPower Performance 6 panels feature a unique parallel circuit architecture that significantly limits power loss from shade and soiling. The result is a high-quality shingled panel constructed with commodity cells, outperforming standard panels in efficiency, performance and reliability.

What is the typical cost advantage of using SunPower Performance panels?

SunPower Performance solar panels are the premium value option offered by Maxeon Solar Technologies. Although Performance solar panels may be priced above most standard panels, this differential is reflected in high-quality materials, superior technology, and experienced manufacturing. While the initial investment is often higher, Performance solar panels offer long-term cost advantages through reliable energy production, a long lifespan, and minimal product and power defects. This translates to lower maintenance costs and consistent energy output over decades, making Performance solar panels a low-risk investment offering substantial value over time.
