Hi all, we are modeling the PV panel for grid connected applications.
Hi Muthu,
First of all you have to decide what kind of AC converter you will use for convert DC energy from your panel to AC energy (eg. H - bridge converter, multi-level converter...).
There are a lot of different topologies of power electronics converter for this application.
You also have to decide if you want have a sinusoidal wave as an output.
best regards,
Leonardo
Hi sir, do you mean by module output equation ?
AC output (kWh) = Irr (kwh/m2) * Area of Module (m2) * efficiency of module * inverter efficiency * power loss efficiency
For example
yearly irradiance in one city is 1500 kwh/m2
1 module area is 1.68m2 (60 cells)
module efficiency = 100 * output of module / ( 1000 * area ) = 16.8% in general
inverter efficiency is 95% (micro inverter) or 98% (string inverter) in general
temperature, cable, mismatch loss and so on is 95% or even lower
Thus, 1 module 1 day output is
(1500 / 365) * 1.68 * 16.8% * 98% * 95% is a little more than 1kwh
In practice, some deviation may have, for example, shading effect, tilt angle, module output +-10% deviation, environment impact (soil, dust, air condition)
If you want to know equation DC to AC conversion block inside inverter, is hard to answer. since, many types of bridge circuit ( harf bridge, full bridge and so on). The function is converting the wave..
