SolarCity Test - A quick guide on the Results Section

The following presents results on metrics considered a priority when assessing the potential for rooftop spaces. It contains four sections: Setting, Installation, Financing, and Environmental benefit.

• The Setting section presents the capacity of solar PV panels that can be accommodated on a selected single (or multiple) rooftops as well as the self-consumption of a single (or multiple) buildings. The section is also tied to a toolset (slider and drawing tools on the map) that can be used to resize the system and tailor the self-consumption ratio as needed to individual cases.
• The Installation section presents the selected area of the rooftop for installing solar PV panels, with annual production and annual consumption in kWh per single or multiple buildings per year.
• The Financing section presents relevant output metrics:
  • Total investment required with total annual revenue for building owners or promoters;
  • Policy costs (generation and installation subsidies), the value created, and the resulting coverage of electricity for end-use and reduction of alternative sources;
  • Financial indicators to guide private and public investments, such as equity internal rate of return (EIRR), payback to equity;
  • Understanding of the broad economic, social and environmental benefits of interventions introduced to the market, for municipal authorities;
  • Financial payment options to help indigent people address concerns regarding significant upfront investments and visualise revenue through dynamic graphs.

  Relevant output metrics are calculated based on two optional financing models:

  • A ‘buy financing model’ where the building or estate owner intends to buy the solar PV system,
  • A ‘lease financing model’ where a private or public investor intends to buy the solar PV system for a community while the building owners do not bear the cost of investing in the solar PV system. The investor will pay the annual rent to the homeowners and gain the profit from selling part of the electricity to the consumers for their self-consumption, subsidies, and the remaining electricity to the grid at a benchmark tariff.

• The Environmental benefits session presents fundamental indicators of the prospective positive impact installations of rooftop systems may have on the environment. Outputs in this section include the estimated CO2, CO2e, PM and NOx avoided and their equivalent carbon emission that can be offset in terms of tropical trees planted and passenger cars taken off the street.
