Approximate Back-up Time

Back-up time in this context is the approximated time a solar system can provide power to load in a day. This largely depends on the battery and the amount of load on the system.
However, the size of the system (i.e. 1KVA, 2KVA, 4KVA etc.) also counts. We sometimes put so much load on the system and immediately the system goes off after few hours of operation, we blame the system to be inefficient.
No, the problem is simple. We did not take into cosideration the amount of load we put on the system and yet we blame the system to be inefficient. The system is absolutly efficeint but how we use it makes it efficient or inefficient.

How then do we enjoy long hours of constant supply on our system? At Suka Wind and Solar energy Ltd, we provide simple solutions to such problems. We have tested and determined how long your system can take you in a day depending on how much load you put on it. The results of our test is presented in a a simple and comprehensive table below.
Note however that, back-up time depends on quality of the battery, age of battery and type of battery.
