Frequently Asked Questions (FAQ)
What size system do I need?
This depends on the loads or appliances you want to run and how often. This also depends on the pitch of surface you want to mount the panels, direction and budget. Your location is also carefully considered. When sizing a system please talk to our staff for carefully considered advice.
How long will my system last?
Systems can be designed to last 10 years or more 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 increase the life of the battery array but the upfront cost is much higher. The system value point might be better running fewer batteries at a deeper discharge rate. Inverters for example have a limited life span that needs to be considered. Consider quality components along with lithium battery options available.
What maintenance is required?
Every system is different we can design a schedule according to the manufacturers specifications and requirements. In general these are easily preformed and do not take too much of your time.
We are big on taking your expectations and how you perceive the system to operate and working through the many factors which effect system performance. Systems are often over sold and people feel they have been let down when 5kw of solar does not mean 5kw of provided energy every hour. Factors like heat, cloud shading and inverting affect the performance of the system and should be factored in and the customer should be made aware of these variances.
