Shading of photovoltaic panels is one of the most significant causes of losses in a pv system. In fact, the shading of 10% of the area of a system could cause a loss of 50%. This disproportionate effect is caused by string design. If there is one shaded panel in the string, the whole string underperforms.

4Kw System consists at installation of:-

Panels: 16 Suntech STP250S (250 watts)
Inverter: Power One PVI3.6 OUTD
Roof Angle: 32°
Direction: -30° (30 east of south)
Shading: Palm tress, removed
Partial shading winter, string 2

System Live: 4th February 2012, approx 2pm

Update 5th April 2017
Panels : 8 Faulty SunTech panels (string 1)
replaced with 7 LG285S1C-L4 panels.

Update 12th January 2023
Panels : 8 Failing SunTech panels (string 2)
replaced with 5 Trina Vertex S panels.

The HF5111B Ethernet to Serial converter Update 17th Dec 2020
The eNet-232 getting intermittent errors, changed for a HF5111B
The Aurora Power One 3.6 OUTD inverter has a usb port and more importantly a RS485, we need network access for the php scripts on the server so we need an RS 485 to ethernet converter. The HF5111B (got it from ebay, China) has a two serial ports, one RS232 and the other can be a RS232/422/485 RS485 port. We need the RS 485 option, easy to set up, 2 wires to strip block in inverter to HF5111B strip block wired straight, T-, T+

Note 1
Solar irradiance is the sun's radiant power (W/m2). Watts per square meter where the square meter is horizontal, i.e., flat on the ground. A square meter ray of energy comming from the sum will cover approximately one square meter on the earths surface when the sun is directly overhead. However early in the morning and in the evening it hits the ground at an angle and therefore each square meter of earth will be recieving less energy and the reading will be lower.

Naked Solar - Formerly Cornwall Solar Panels

I highly recommend them, planned and fitted with first class service from a local company.

Give them a call and please mention Newquay Weather. 		cornwall solar panels

There are few software solutions to gaining access to the inverter data, all require the use of a pc. The inverter comes with Aurora Communnicator CD pdf manual, there is also Aurora Monitor, a Java application, Aurora Monitor and a command-line program for Linux Aurora

My aim was to write php scripts to run on the server, which will do away with the need for a home pc, the script is called by a cron job every 2 mins, generate the data as seen below and also produce graphs. See the eNet-232 Ethernet to Serial converter section below for more information.

5-4-2017 - 8 Suntech panels string 1, being replaced with 7 LG panels from 08:42 to 11:06
20-11-2016 - PAY BACK approx 09:30 took 4 years 9 months 17 days, based on FIT payments only
