What are the steps involved in getting an off-grid power system design & quote?
The process can be summarised into 6 stages as follows.
[ 1 ] Assessment of energy requirements and site location.
As mentioned in the previous section, this is the most important step in the process.
Because each aspect of system design that follows will depend on this information, it is worth spending the time to complete this step as thoroughly as possible.
Preliminary system size and price range can be advised after a few questions about the purpose of the system and the main power-consuming appliances that it will supply power to.
i.e. Is the system for a farm shed? Irrigation pumps? family home? summer weekender? stockyard lights & power?
Proceeding further will involve a deeper look into the site specifics and energy requirements.
There are a few ways to do this and a common method is to fill out a load assessment sheet with appliance power consumption and estimated run times. From this, we can determine the daily kWh energy requirement.
Additionally, we’ll gather information about some other aspects that can affect design options.
• major appliances
– air conditioning, hot water, cooking, large pumps, workshop equipment (welders/air compressors/hoists)
• seasonal or year-round use, occasional or full-time use
• effect of seasonal variations – eg; winter heating, summer irrigation, summer AC
• time of consumption – day/night
• your choices & preferences
• battery autonomy – 2 days, 3 days? (affects the size of the battery bank)
• backup generator options
• upsizing solar array or battery bank capacity
• future considerations – for example; plans to increase capacity or add wind/hydro in future
[ 2 ] Designing the system
The next stage will be to produce the system design – with assistance from our specialised system design software. This will be carried out by our qualified, accredited, and experienced off-grid design team.
[ 3 ] System proposal
Once we have completed the design stage, we’ll present to you a comprehensive system proposal that includes energy production and consumption estimates, solar potential & yield estimates, financial simulations (ROI, system lifetime savings, etc), system component info & specs.
At this time we’ll consult with you to discuss your option preferences and any budget considerations.
[ 4 ] Design approval and quote acceptance.
Upon your acceptance of the system proposal, we will finalise the design for the chosen system and options.
A job order will be created and we’ll send details for a deposit payment to get things underway.
[ 5 ] System building and testing
Our technicians will build your system in our workshop, program the configuration settings, and run it through a testing procedure. Once testing has been completed, we’ll get the system ready for deployment to the site, or pack it for delivery in the case of Plug and Play/DIY kits.
[ 6 ] Installation & Commissioning
The final step will be to coordinate with you to schedule installation.
Your system will then be installed and commissioned by our technicians.
Monitoring & communications access will be set up and we’ll provide you with a system introduction and briefing on operation and maintenance, along with a comprehensive system owner’s manual.
