Solar Energy Monitoring System Addon

Job Description:

What I have now:

1. I have a C++ program that can read values from multiple brand of inverter and write data to MongoDB.

The Program will read an configuration file for station object on DB to know what kinda inverters installed at the station to select proper driver.

2. A web app that can retrieve that data from MongoDB.

What I need for this project:

1. I need to add a timer to the C++ program, the program only read inverter 15 mins once from 6 a.m. to 6 p.m.

2. I need the web app can show the station statistics ( the sum of energy generated today and power generated belong to this station) and show it as a bar chart view, one bar/hr.

3. I need the web app can add new station object to DB and download the configuration file.

4. User & Role Management, Administrator can assign which user can monitor which station.

5. Export the History Data as xls format.

P.S. Feel free to ask me for more detail if you ain't clear for what i mention above.
