Amounts presented in the Rate my Roof web app are hypothetical only and assume that your roof is covered with 100% solar panels, which is never possible. Origin does not intend for, and you should not rely on, the Rate my Roof web app as representing actual savings or generation you could experience. Actual savings and generation will need to take account of purchase and installation costs of the solar system, ongoing maintenance and replacement of parts, together with a range of other factors including your exact location and available sunlight, system size, system degradation over time and your consumption pattern.
The Rate my Roof web app assumes:
daily output for your hypothetical system size in your State or Territory capital city based on Clean Energy Council Consumer Guide to Buying Household Solar Panels, 2011
you consume 5% of energy generated by your hypothetical system and export 95%,
a consumption rate equivalent to Origin's best generally available market rate with discount in your state or Territory (or where Origin does not retail electricity, the regulated tariff) and an export rate equivalent to the minimum available Feed in Tariff in your State or Territory, and
no CPI or degradation of system performance over time.
