Solar Installation Costs and Advice

To simplify common questions customers have asked over time, we have decided to create a summary to answer the typical questions asked regarding sizing, costs and other various aspects to installing solar and solar coupled with battery systems.

Firstly we will direct the information towards customers with solar already and wants information about adding batteries. The first question we ask is if the customer has solar currently. If so, we need to establish if the customer is on the premium feed in tariff or just the normal 6-8 cent payback rate.

For customers wanting to install batteries to their existing system and are on the normal feed in rate of 6-8 cents we simply provide information and pricing for retrofitting their current system over to our hybrid battery based Grid as Backup system.  In most cases this involves changing over the inverter which is normally simply a grid connected basic model to our Hybrid, Battery interfaced, Blackout protected inverter and of course coupling with the battery bank.

If the customer has solar already and is on the premium feed in tariff, we advise that any changes made to the existing system will render their premium feed in tariff to be no longer in effect.  At this stage, we discuss the potential to add a secondary off grid system including panels which will allow the customer to free up the existing system to purely feed back to the grid to maximize their payback.

By installing a second system that does not interfere with the grid, the customer does not effectively change any of the existing equipment or configuration of the existing system therefore they get to keep their premium feed in tariff.  So for a customer with a 5kW system in Queensland for example, generating 30kW per day and using 20kW per day should be getting a feed in payback of around $6.60 per day for the unused 10kW (10kW x $0.66 premium rate). By having a secondary system providing the cover for the daily 20kW usage by the house, this would free up the 20kW to be fed back to the grid along with the original 10kW therefore making it a total of 30kW per day fed back at the premium rate. This is an incredible $19.80 per day payback or $7,227.00 per year.  Please be advised there is an unlikely possibility that the premium feed in rate can be removed by the electricity retailer by mistake and Solar Heroes will assist in highlighting to the retailer that the new system is completely isolated from the grid and does not classify as being a change to the exsisting system.

So now that we have answered questions for customers with solar we can now begin clarifying the typical questions and answers for customers seeking complete solar packages both without and with batteries.

For customers not wanting batteries, we offer systems comparable to TV offers with the difference being that we do not sell any equipment below the quality level of tier one.  This means that although you may find cheaper prices elsewhere for basic solar installs, it is important to check the brand and output ratings for the equipment used. The prices we offer include RET government rebates for the solar panels.  As an example, a customer in Queensland will get 62 credits for 3kW worth of panels and 103 credits for 5kW worth of panels. The current rebate pricing at the time this article was written is $38.00. So for customers in Queensland buying a 5kW system, they are receiving a rebate of $3914.00.

Customers wanting a complete system including batteries requires a little more detail in explanation. First of all when dealing with batteries we need to use a different inverter with far greater capabilities than the standard grid tied inverter shown above. With these capabilities come a larger cost because of the extra components involved in the inverter such as battery management and charging functions and isolators and relays that allow the system to work and provide power in the event of a power outage.
