Solar Panel Efficacy in Egyptian Energy Market

Average Solar Radiation per Day in Cairo, in kWh/m2 / day https://www.pveducation.org/pvcdrom/properties-of-sunlight/average-solar-radiation#

Jan 3.29 kWh/m2 / day
Feb 4.32 kWh/m2 / day
Mar 5.35 kWh/m2 / day
Apr 6.42 kWh/m2 / day
May 7.32 kWh/m2 / day
Jun 7.79 kWh/m2 / day
Jul 7.54 kWh/m2 / day
Aug 7.02 kWh/m2 / day
Sep 6.12 kWh/m2 / day
Oct 4.97 kWh/m2 / day
Nov 3.68 kWh/m2 / day
Dec 3.09 kWh/m2 / day

Avg = 3.29 + 4.32 + 5.35 + 6.42 + 7.32
    + 7.79 + 7.54 + 7.02 + 6.12 + 4.97
    + 3.68 + 3.09
    = 66.91 kWh/m2 / day

66.91/12 months = average 5.575 kWh/m2 / day

Current Energy Cost in Egypt, in EGP/kWh https://attaqa.net/2022/06/13/%D8%A7%D8%B3%D8%AA%D9%85%D8%B1%D8%A7%D8%B1-%D8%AF%D8%B9%D9%85-%D8%A7%D9%84%D9%83%D9%87%D8%B1%D8%A8%D8%A7%D8%A1-%D9%81%D9%8A-%D9%85%D8%B5%D8%B1-%D8%A8%D8%B9%D8%AF-%D9%82%D8%B1%D8%A7%D8%B1-%D8%AA%D8%A3/

0 - 50 kWh:        EGP 0.58/kWh
51 - 100 kWh:      EGP 0.68/kWh
0 - 200 kWh:       EGP 0.83/kWh
201 - 350 kWh:     EGP 1.11/kWh
351 - 650 kWh:     EGP 1.31/kWh
0 - 1000 kWh:      EGP 1.36/kWh
0 - >1000 kWh:     EGP 1.45/kWh

Let's take average to 1 egyptian pound per kilowatthour, so

Solar yearly return

5.575 kWh/m2 / day * EGP 1/kWh * 365 days

= EGP 2034/m2 / year
