Your amortisation period is the amount of time it will take for your investing in solar electricity to begin “paying for itself”. As electricity costs increase, your amotisation period gets shorter.
If your business is largely admin based and operates during the day, then we recommend a grid tied system. The main energy requirements are day-time with some peripheral usage outside of that window. This would greatly reduce risk of downtime as a result of “load shedding” as well as the loss of productivity that comes with it. The amortisation period on a grid tied system is the shortest. A the advantage of this type of system is that it often has excess energy.
Pre-paid and meter type systems all measure units. The best indication of what your requirements are is to take consistent measurements twice a day (ideally sunrise and sunset).
This will allow you to gauge your PV requirements for daytime usage and the potential battery bank required to cover your nocturnal usage.
This is dependent on what you aim to achieve with your system. You can change your habits so that some things done at night can be done during the day and then utilise cheaper PV panels than more expensive battery banks.
