    Good day.

    I hope you could assist me with some advice please, as getting any reaction from solar companies, seems impossible!

    I reside in Augrabies and do irrigation from an irrigation canal on the lower side by means of flood irrigation. On the higher side I use electric water pumps. The bigger one for irrigation and the smaller one for drinking water to a tank.

    I currently use power from Escom, but want to change it to solar power.

    The big pump takes water directly from the canal and it is mainly used during daytime.

    The small pump is on a borehole which is 14m deep and the watertable stands at 8m. It is usually used during daytime as well.

    I would be so grateful if you could assist me with the correct different solar equipment needed, please. The battery, solar panels, inverter and controller.

    Thank you so much.

    Friendly regards.

    I need a excel spreadsheet that calculate earthmoving machine’s working hrs per day worked exmple machine start hrs is 525 next day beginning hrs is 550. Hrs worked is 25 hrs and per month and also in the calculation it must redflag you on when its due for maintenance service. Maintenance services is normaly after 250hrs, 750hrs, 1000hrs or 2000 hrs. as soon as the machine reach his next due maintenance service hrs, the spreadsheet warn you by redflagging the hrs.
    Feel free to contact me if you need any other information.
