# PVSOL Report!

## Recommended Posts

Hello,

I'm a beginner with PVsol and I have some questions, I hope you can help me with!

1- in the "The yield", the PV Generator Energy (AC grid) value for one of my example is  865,154 kWh

Direct Own Use=548,649 kWh, Grid Feed-in=316,505 kWh, Solar Fraction=35.8 %

I need to know what is Direct Own Use, Grid Feed-in and Solar Fraction is!?

2- in the Simulation Results/Results Total System under PV System we can find the same value for PV Generator Energy (AC grid) and that okay.

but under Appliances we can find that Energy from Grid=667,163.2 kWh and Solar Fraction=56.5 % not 35.8 % ??

In the Level of Self-sufficiency and covered by grid value is 983,668 kWh/Year where this number came from? and the Level of Self-sufficiency=35.8 % equal to Solar Fraction above.

hope you can advice me about the final report in order to understand all given values.

Thank you

Luai Doumet

Hello Luai,

in order to explain the direct use, grid feed-in and so on, let me copy a energy flow diagram from PV*SOL here:

Direct own use is the fraction of the PV energy that is used directly to cover the loads, in this case 2830 kWh. The own power consumption ratio would be 2830 kWh / 9160 kWh = 30,9 %. The solar fraction is the amount of the consumption that can be covered directly by the PV. So in this example it would be 2830 kWh / 8401 kWh = 33.7 %.

Concerning your second question, it would be very helpful if you could send me over the project file (here in the forum as private message).

Kind regards,

Martin

Thank you Martin,

Okay the project file will be sent to you in private,

Hi LuaiD,

thank you for the project. The solar fraction in net metering projects is the PV generator energy (AC) divided by the consumption, so in this case

865154 kWh ÷ 1532128 kWh = 56.5 %

The level of self sufficiency is the fraction of the consumption that has not to be covered by the grid, so

1   -   ( 983668 kWh  ÷   1532317 kWh ) = 35.8 %.

The difference between "Energy from Grid" in the consumption section and "covered by grid" in the section "Level of self-sufficiency" is the grid feed-in. "Covered by grid" is everything that comes from the grid, "Energy from grid" is "covered by grid" minus the grid feed in.

Hope that helps, kind regards,

Martin
