Type Private Industry Photovoltaics Founded 2006 Headquarters USA, Germany, Japan, Israel Products Distributed PV power harvesting and monitoring systems Website solaredge.com SolarEdge is a provider of photovoltaic power harvesting and monitoring solutions which aim to increase energy output while lowering the cost of energy.[1] The company has offices in the US, Germany, Japan, and Israel. Contents 1 Background 2 Offering 3 Technology 4 Awards 5 References 6 External links // Background [2] Traditional photovoltaic installations are typically characterized by a centralized inverter or string inverter architecture. In this topology the inverter performs Maximum Power Point Tracking (MPPT) for large quantities of panels as a whole. Since panels are connected in series to form strings, the same current must flow through all the panels, so the inverter continuously adjusts the electric current in the system to find the average optimal working point of all the panels. As a result, potential power may be lost whenever a mismatch exists between panels.[2][3] Panel mismatch is unavoidable in many cases, due to panel manufacturing tolerance, partial shading,[4] uneven soiling, or uneven tilt angle. In addition, power may be lost also due to slow tracking of dynamic weather conditions caused by moving clouds,[5] and on extremely hot or cold days when the system DC voltage may exceed the inverter permissible input voltage range. Several other challenges are faced by the traditional (centralized) photovoltaic approach: system design is constrained by the need to match all strings' length and orientation, monitoring visibility and fault detection is limited to the inverter (or in some cases to string level), and high DC string voltage poses risk of electrocution to installers and fire fighters.[6] Offering [1] SolarEdge delivers a distributed system that tackles the aforementioned challenges. Energy loss due to panel mismatch is prevented by performing MPPT for each panel individually. String voltage is kept fixed at all times, so strings can be combined regardless of length, tilt, or type of panels used. Continuous performance measurement enables online monitoring and fault detection at panel-level. Installer and firefighter safety is enhanced by shutting off the DC voltage whenever the inverter is disconnected. To achieve the above without raising the cost of the system, compared to standard inverters, SolarEdge provides panel optimizers as well as its own inverter and monitoring web portal. The solution is applicable for a wide range of applications, from residential roofs to large scale solar farms. Technology The SolarEdge system consists of three components: SolarEdge PowerBox: The PowerBox is embedded into each panel by panel manufacturers instead of the junction box, or retrofitted by PV installers onto regular panels. The PowerBox optimizes energy output by performing Maximum Power Point Tracking (MPPT) individually for each panel. Further, the PowerBoxes automatically maintain a fixed string voltage. This gives installers greater flexibility in designing optimal PV systems (such as combining in parallel unmatched strings), and higher fault tolerance, because the system automatically remains within permissible voltage range regardless of the string length, temperature or shading. SolarEdge Inverter: The SolarEdge Solar inverter is only responsible for DC to AC inversion because MPPT and voltage management are handled by PowerBoxes separately for each module. Consequently, it is a simplified, reliable device. The fixed string voltage ensures operation at the highest efficiency at all times, independent of string length and temperature. SolarEdge Monitoring Portal: A web-based application provides module-level, string-level and system-wide PV Monitoring. The software automatically provides alerts to a wide range of issues affecting energy generation that might otherwise go undetected. SolarEdge monitoring is built-in for each PowerBox and transmitted over the existing power lines.
