One of the new features of the 2021 Series of the SOLergo software is project comparison, the objective of which is to compare the economic return between several projects carried out in the software and display the result in a spreadsheet.
To carry out the comparison, it is necessary to calculate in advance the economic return of each of the projects carried out in SOLergo.
After that, accessing the Tools menu – “Compare projects”, a window opens that allows you to add the projects that will be analyzed.
In the window, the “Last Analysis Date” is displayed for each project, understood as the date on which the economic return calculation was saved.
If when adding the project it displays in the “Date ” this means that the calculation has not yet been performed. After carrying out the procedures above, simply select the route and the name of the spreadsheet.xls to save with the results.
Thus, the user can take advantage of this functionality and carry out various project scenarios in the software, such as the use of different modules and inverters, solutions with batteries and auxiliary generators and also power optimizers.
Furthermore, it is also possible to compare projects with the positioning of different modules, on the ground and on the roof, with fixed angles or trackers, and other possibilities.
In the example in the image below, an analysis was carried out for the same location using string inverters, microinverters and power optimizers in each of the projects.
As shown in the image, the spreadsheet displays a comparison of the energy produced, revenues, costs, invested capital, accumulated cash flow and the amortization period for each of the scenarios, in addition to other financial information.
This way, the user can send the results of the spreadsheet to the owner with various investment scenarios, without necessarily generating economic reports for each project carried out. In addition to the comparison functionality, the following tools are available:
- Two-phase system management, with central neutral between phases;
- Management of single-phase inverters in two-phase systems;
- Update of the remote self-consumption functionality;
- Layout design with dynamic input;
- Optimized representation of drivers in the system layout;
- New calculation method for NPV and IRR considering Financing;
- New method of calculating the Amortization Period considering Financing;
- Extension and update of the photovoltaic modules and inverters database.
