Procedures and Processes

Products that are delivered to the solar test and monitoring facility will have their product details logged, and an entry report compiled. The entry report will consist of a flash test and an IV curve, this is to ensure that the products delivered to RETI are within the power tolerances as detailed on the products specification sheet. If the product is not within specification and over or under performs, or does not give an accurate indication of the product that would be released to the market, the product will be rejected and returned to the supplier for re-evaluation.

RETI is not prepared to have products field tested that do not represent a product that is from the general production line. It is RETI’s intention to reduce the likely hood of an over performing panel, or Golden Panel, to deliberately miss represent what the industry and consumer can expect in field conditions.

Once a product has been flash tested in our sun simulator, and has passed the entry level report, an IV curve will be generated as the base line for the product. The module will then be installed at the solar test facility for monitoring, this is the data which all calculations and Solar panel performances will be based.

When a Solar Panel module is fitted at the solar test facility, each unit will have a solar analyzing unit installed which will measure the DC voltage and DC current output of the panel to capture power performance of the module. In addition to data from the solar modules, the test field employs several highly accurate devices to continuously measure solar irradiance, UV radiation, panel temperature, ambient temperature and wind speed. Solar modules and weather data is then stored in synchronized databases to ensure précis correlation for later analysis.

For inverter monitoring, RETI will include enough solar panels to suit the size of the inverter being monitored. RETI will install the Inverter analyzer unit which measures DC voltage and current before the inverter, and AC voltage and current after the inverter for performance monitoring in real world conditions. The standby usage and operational efficiencies are also recorded to give the true overall efficiency of the inverter. All weather data is captured stored and synchronized in a secure data base for further analysis.

All solar systems at the RETI facility are installed to current Australian standards as set out by the Clean Energy Council (CEC)guidelines by approved installers. The panels are fitted to the nominated area using approved mounting kits and set to the optimum angle and orientation for the location chosen (27Deg tilt, facing true north for Brisbane, Australia). The monitoring units measure system performance by measuring the DC voltage and current before the inverter, and measuring the AC voltage and current after the inverter using the latest in monitoring software and hardware.

Each system is measured o capture the maximum power produced by the solar panels every 2 seconds and averaged out over 10 minute intervals for the web preview. Two second data is available on request via a contracted parties login.

Reports can be generated whenever required with more detailed analyses available through a login provided to the contracted monitoring parties.

On completion of installation, a certificate of MONITORING is presented to the contracted party for display, and can be used as part of promotional and marketing material. A logo of monitoring is provided for insertion on specification sheets and product promotional material, this is available for use only during the contracted monitoring period.

The web preview is online 24/7 and will indicate when the units are operational or on standby. The standby view (generally Night time) will display a night sky, the daytime views will change when weather conditions change, if the sky is overcast the view will reflect this as close as practical to real conditions.

Ongoing Monitoring and Reporting

Once a system is installed and operational at the RETI field monitoring facility, a comprehensive maintenance program is carried out each month.

We believe that all environmental conditions are dynamic and vary greatly depending upon location, therefore it is RETI’s policy to represent the products being monitored at their full potential by regularly cleaning all products being monitored at the RETI facility.

Each month RETI cleans the solar panels with a biodegradable non corrosive product, and conducts a visual report on the condition of the panels in the system, if any changes in appearance or construction are noticed, the contracted party is notified of the findings for their consideration.
