I happened to be on site for a Plumbing Job, and Walked Past this Inverter.

Results Calculated:

Labrador QLD 4215

5 Kw Inverter
16 x 250 watt Panels on Roof
19/04/16
Reading - Total 20983 KWh @ 15.21pm produced 6.259 Kwh for the Day?
http://pvwatts.nrel.gov/pvwatts.php
Site Calculation Estimate Allowing for Age = 22255 Kwh Total in Time.(allowing loss)

30660 Kwh Total Time is what you should have in my Calculation @ $0.50/Kwh
= $4838.50 Estimated Loss of Production by Not Maintaining!

How can I get the message to you all with Solar that you are Throwing away alot of Money?

These Results I post are collected Around the Gold Coast QLD

And are Actual Readings, not just Made up Information!
I Calculate my Results over at least 6 - 12 Months, Not from 8am to 12pm in the same day! (as other websites show!)
