Frequently Asked Questions (FAQ)

What size system do I need?

This depends on the loads or appliances you want to run and how regularly. The pitch of surface you want to mount panels, direction, budget and where you are located. Many factors are carefully considered when sizing a system so please talk to our staff for a carefully considered approach.

How long will my system last?

Systems can be designed to last up to 10 years but upfront costs and value for money should be considered. For example batteries have a DOD (depth of discharge) the less the battery is discharged the longer it lasts, if you double the amount of batteries increasing the system capacity they will not discharge as deep therefore increasing the life of the battery array but the upfront cost is much higher and the system value point might be better running fewer batteries at a deeper discharge rate. Also, inverters for example have a limited life span these need to be considered. Consider quality components also lithium battery options are available.

What maintenance is required?

Every system is different we can design a schedule according to the manufacturers specifications and requirements. Generally these are easily preformed and do not take too much of your time.

Expectation vs reality?

One of our main focuses is taking on your expectations or how you perceive your system should work and working through the many factors which effect system performance. Systems are often over sold and people feel they have been let down. 5kw of solar does not mean 5kw of provided energy every hour because factors like heat, cloud shading and inverting effect the performance of the system and should be factored into the system where possible, while ensuring the customer is aware of these factors.
