Please consider the above links. The first link includes a new gap minder interactive graph. Please consider this when reading over our new Homer Energy models for locally manufactured devices.

We will be starting to upload models and discuss the pros and cons between imported versus locally manufactured electricity generating devices in low HDI countries for hospitals, health centers, businesses, domestic use, and schools.

Stay tuned and we look forward to feedback.

Comment by Jazreel Tang on January 22, 2011 at 10:12am: Hi, I am a beginner for HOMER.

i am doing a final year project for my last semester in Universiti Tenaga Nasional in Malaysia. My project is about designing a 1MW solar PV plant in campus.

I was wondering why do my design could not get IRR, simple n discounted pay back where my current base is the 1MW PV system after i had simulated.

I would like to ask can HOMER calculate energy pay back period? I was confused by the simple pay back and discounted pay back it meant.

After i had simulated my design, Homer did not calculate the IRR, simple pay back and discounted pay back for me. I am not sure which part did i do wrongly.

I hope you could spare some time to help me check my design and give some opinions. The hmr file is attachedProject5.hmr.

Looking forward to your reply.

Thanks.

Regards,
Jazreel
