ASSUMPTIONS & DISCLAIMER
1
The Standard Test Condition rating (STC) assumes a standard set of optimal operating conditions (25°C cell temperature, 1000 W/m
2
and an air mass of 1.5). The STC rating is most often used by manufacturers to classify the power output of PV modules. To calculate the
system's energy production for any future year, the expected degradation in system performance is included (See "PV degradation", in
table below).
2
Energy Output is calculated based on historical solar irradiance at the given location. A typical meteorological year is selected using
statistical methods. Factors including panel tilt, orientation (azimuth), and system efciency are taken into account.
3
System efciency is estimated to account for losses caused by a variety of factors. These factors include intermittent shading, cable
losses, dirt, scheduled downtime, manufacturer tolerances, inverter efciency for DC to AC (this does not affect off-grid DC only
systems), battery round trip efciency, and other factors.
4
Utility electricity price ination is adjusted based on the given location.

Australian Small-scale Technology Certicates (STCs) are an incentive provided under the Renewable Energy Target. One certicate is
equal to one megawatt hour of eligible renewable electricity either generated or displaced by the installed system. [ONLINE] Read more

Note The system design may change based on a detailed site audit. Estimated savings are based on past electrical usage and utility rates
provided by the customer where applicable. Actual system production and savings will vary based on nal system design, conguration,
utility rates, applicable subsidies and your energy usage post-solar installation. Utility rates, charges and fee structures imposed by your
utility are not affected by this proposal and are subject to change in the future at the discretion of your utility. The production
calculations in this report are based on historical climate data for the site location and represent typical estimates of future solar
production.
