Reduced BoS Costs - System Comparison

SolarEdge Solution

Typical String Inverter

26-50 modules per string (up to 15.3kW)
Uneven strings can work in parallel
Only shaded modules produce less power. Other modules on string are not affected
Any module size or type can be used
Modules can be installed in any orientation/tilt

Limited string length
Must match string lengths per MPP tracker
Shaded modules reduce total power collected from all modules on that string
Cannot mix different types of modules
Locked in to same orientation/tilt per MPP tracker

SolarEdge cabling

Cabling Comparison

The SolarEdge solution allows up to 15.3kW per string. Longer strings allow for fewer strings to be connected, resulting in less wiring, fewer combiner boxes, fuses and other BoS components.

In this 100kW example, the BoS cost saving amounts to 1.2/Wp

Inverter Replacement/Warranty Extension

Most standard inverter warranties typically range between 5-10 years. This means that inverters require at least one replacement during the system lifetime. Funds need to be set aside to cover replacement costs or alternatively, inverter warranty extensions should be purchased.

Typical 20-year warranty extensions cost 3-4c/Wp. With SolarEdge:

70% of the inverter system cost, namely the power optimizers, have a standard 25-year warranty.
SolarEdge inverters have a standard 12-year warranty, with warranty extension up to 20 years costing as low as 1c/Wp. This amounts to a savings of 2-3c/Wp.

O&M Cost Savings

SolarEdge can enable 15%-25% savings on annual O&M costs
