We are a national solar wholesaler and provide design assistance and equipment to our customers. The intent of this project is to create a GUI that we can integrate on our website via Wordpress that will step through the design process for a solar system. At each each step, the user will have to enter a particular characteristic of the system they wish to design.
On the last page there will be a fixed list of items, the GUI will calculate all the quantities of those items and display them. There will be an option here for the user to enter their personal details and have that table of information emailed to them.
Throughout progressing through the GUI, the data entered into each of the data fields is to be stored as a variable that can be used in simple calculations later.
YOU will not have to do these calculations as they are simply too hard to explain. But YOU do have to write the program so it is easy for our resident programer to edit the script and enter these calculations. Please write it so that, the quantity for each item is already a variable, we just simply have to enter the formula and the script will output the value in the GUI.
In the Attachment, there is a "Visual Concept" and a "Technical Concept" for each of the steps in the GUI.
If you have any questions or would like any more information please don’t hesitate to get back in touch.
I am looking for a mix of experience and value
