SolarEdge Installations

SolarEdge System

SolarEdge was the first to successfully commercialize power optimizers, a device that offers module-level maximum power point tracking (MPPT), before feeding back the electricity generated into a central inverter. Their central inverters have a standard 12 year warranty, and typically fail after about 13 years. All SolarCal systems using SolarEdge include an extended, 25 year warranty. When your inverter eventually does fail, you will receive a brand new one.


Power Optimizers

The Power Optimizer is a DC/DC converter which is connected by installers to each solar module, turning them into smart modules. Optimizers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually, and sending performance data to the monitoring platform for cost-effective module-level maintenance.

Each Power Optimizer is equipped with the unique SafeDC™ feature, which automatically reduces modules' DC voltage to a safe level whenever the inverter or grid power is shut down (unless the inverter is operating in backup mode).

Optimizers mitigate module mismatch-loss from manufacturing tolerance, partial shading, and aging. They deliver up to 99.5% peak efficiency.

HD-Wave Inverter

Because Maximum Power Point Tracking and voltage management are handled separately for each solar module by the Power Optimizer, the single phase inverter is only responsible for DC to AC inversion. Consequently, it is a simpler, more cost effective, more reliable solar inverter. The fixed string voltage ensures operation at the highest efficiency at all times independent of string length and temperature.

99% weighted efficiency
Up to 200% oversizing allowed
High reliability due to lower heat dissipation
Built-in module-level monitoring
Communication via Ethernet, or wireless connectivity
Suitable for outdoor and indoor installations
Integrated arc fault protection and rapid shutdown

12 year Standard Warranty

Solar Panel Overview

Q Cells and REC are both established, bankable companies having a large share of the solar panel market. Panels are all-black, for a sleek look. Although a optimizer or central inverter may fail over the life of your system, the odds of a solar panel failing is minuscule—they have no moving parts other than electrons. The panels also routinely exceed their efficiency/output ratings. Your odds of ever having to make a solar panel warranty claim are exceedingly small.

The REC panel is slightly more efficient, producing 92% of first year power in year 25 (vs 86% for QCells), but costs .30¢ more per Watt.
