| SOLAR PHOTOVOLTAIC POWER LOSSES & REMEDIES |
|
| Coupling losses |
Originated by the connection of photovoltaic modules with different
characteristics; this phenomenon is critical in series association |
| Dust losses |
Which results in a smaller capture of solar radiation |
Angular/Spectral
losses |
The power of a photovoltaic module is directly connected with the
standard conditions. But in normal operations conditions, the solar
radiation & solar spectrum differ from standard values, resulting in losses |
| Voltage losses |
The cable resistance to the flowing current generates heat, and that
translates to energy losses “Joule effect” |
Nominal power
losses |
The selected product guarantees the peak power of the photovoltaic
module in a bandwidth of P*, that is contained between P* ± 3%. |
Inverter efficiency
losses |
The energy transformation generated by the solar modules, DC into AC, is associated
with losses inherent to the solid state electronic process of the equipment used |
Maximum Power
Point Tracking
losses |
The photovoltaic inverter uses a (MPPT) algorithm to ensure that most of
the energy from photovoltaic array is transferred to the grid, and the
equipment is working at nominal power for longer periods of time. An
incorrect application of this algorithm can lead to energy losses |
| Shadow losses |
A dynamical simulation of the installation to be made to prevent and minimize
shadowing on the solar power station that could affect its output |
Temperature
losses |
The ambient environmental conditions of temperatures vary from the ideal
factory conditions (STC at 25º C) hence losses in actual generation |
|
|
| |
| Remedies |
- Proper Engineering and Technology
- Photovoltaic modules to be chosen based on the power output from the flash test report and not on label value
- Proper Professional Management for Planned and Periodic Maintenance
