December 12, 2017

The PDF report didn’t generate in iOS11. This is issue is solved in this version and the screens have been modified for use on the iPhone X.

1.4

October 16, 2015

On the start screen 'Payback time' and in the side menu, the 'PDF' option is added. The type of reporting depends on the choice of the type of financing (Private or Business) and the funding (by savings, hypothec or loan). After making those choices and the input of the other fields, the results can be displayed as a PDF and send by mail. You can also send the mail to yourself and save the attachment on a PC or print the PDF.

1.3

March 30, 2015

The lifespan of the inverter is now also included in the table and graphs of the hypothec and the loan and a change is realized to fit 25 rows in the table 'Savings' on one screen of the iPad without scrolling.

1.2

February 16, 2015

Two extra fields are added to calculate the savings over 25 years: - Lifespan of inverter after commissioning - Required budget for replacement inverter There is a chance that the inverter will be broken within 25 years. 15 years is filled in as the standard value for the replacement of the inverter after commissioning. The hypothesis is that you buy a new inverter and finance this from your own capital (and therefore this does not affect the screens with the datasheets 'hypothec' and 'loan'). In the datasheet 'Savings' the row of the year after the replacement will be displayed in a different color.

Description of Solar ROI

Solar ROI is the first free independent tool, which calculates the payback period of solar panels without commercial involvement. R.O.I. stands for the term return on investment. ROI = income per year / investment With Solar ROI you can compare tenders and the higher the ROI, the sooner you have recouped your investment. However, the payback time in years is dependent on several factors. In a project, you should compare the result with the situation while you are doing nothing. If you would not buy solar panels, would you leave your money on the bank and receive interest or will you spend it for something else? In the first case, you may also have to take in account the property tax, which you have to pay in some countries. Or would you rather take an additional hypothec on your house to fund your solar panels. In some countries, you may deduct the interest from income tax. The first choice you have to make in the App is whether you will invest as an individual or as a company. The next choice is whether you fund your investment through savings or are you going to invest through a hypothec or loan. The app instantly calculates ROI with some default values for savings, hypothec or loan, but you can change the settings for 'Savings', 'Hypothec' and 'Loan'. Then enter the required budget. You can request estimates from suppliers of solar panels.. The results can be shown in a table or a graph. The tool is not a black box and all calculations are displayed in datasheets and graphs.
