PV solar design software is a design tool assisting engineers/ solar designers in their grid connected PV systems design by performing detailed and lengthy calculations in accordance with Australian Standards and Clean energy Council guidelines. It reduces time,saves money and eliminates human errors. This software performs detailed technical calculation by calculating the PV array and inverter configuration and balance of systems. It calculates required system size (kW). Also performs financial calculations, proposes product specification and compares 2 different systems energy yields.

The software consists of several parts, each part performs a different calculation. First part calculates the PV system Inverter and array configuration and also Balance of System(BOS) given specified inverter and PV module. Second part calculates required system size (kW) based on the required daily, monthly or annual yield (user to choose duration from drop down list)also can size it based on the percentage of energy to be reduced off total monthly energy consumption. Third part calculates the system lifecycle cost, lifecycle income($), return on investment (ROI) and Levelized cost of Electricity (LCoE). Fourth part proposes specification of inverter and PV module only by providing required system size(kW). Fifth part of the software compares 2 different systems by their annual yields and monthly energy yields shown on a chart to improve system performance by selecting most suitable products or by achieving the best PV module tilt and orientation angles.RED COLOUR:INPUT FIGURES BLUECOLOUR:OUTPUT 4-User inputs array configuration, cable 1-User inputs inverter and PV length and required voltage drop.
