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?
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.
Every single panel is electrically tested and inspected for cosmetic criteria at the end of the production line. Regardless of the cosmetic grade, the cosmetic effects do not affect performance or reliability.
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 electric 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 in shade and soiling. The result is a superior shingled panel constructed with commodity cells, outperforming standard panels in efficiency, performance and reliability.
We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 30 years of operation when compared to Conventional mono PERC Panels1.
SunPower® Performance solar panels use high efficiency mono PERC cells, while Maxeon panels use SunPower's proprietary back contact technology developed for our Maxeon panels.
