Your “Rule of Thumb” Guide to Determining What Size Solar PV System You need

At Premier Solar Queensland we are concerned with how many reports we hear of consumers being unhappy because they have purchased a Solar PV Grid System from some other company that they were told would meet their families electricity requirements, but now they are still receiving electricity bills……..unfortunately there are a few solar companies giving the rest of us a bad name who will give inaccurate information to make a sale, by promising performance and output from small KW systems that simply can’t achieve that in any environment.

As a consumer you need to be well educated as to what your household electricity usage is and how that translates into being a set minimum requirement for the KW size needed for your new Solar PV Grid System for it to be able to produce that output even on cloudy days, so that you won’t need to be still purchasing some electricity from “the grid” to top up it’s shortfall….

The table below has been put together for your benefit by our Chief Technical Officer Michael Berris to allow you to quickly take your average quarterly electricity bill amount and move across to match it with the system size to deliver that matching output…..you may be surprised to see how big you need to go! Unfortunately when solar system prices are advertised on special it is always for very small KW sizes which are really quite inadequate for most situations……..so yes you may have to pay more initially then you were expecting, but your return on investment over the 20 year life of the system will be significantly higher!

When we quote we provide our customers with an accurate “Return on Investment” table which shows you how long it will take at current electricity prices for your system to completely pay for itself in electricity bill savings, currently this is roughly 5-7 years, and after that for another 15 years or so it is purely money in your pocket………. So yes solar power can definitely be an excellent financial investment, but only if you install the correct system to match your situation and requirements.

At Premier Solar Qld we will always provide you with expert, accurate and impartial advice because we are here to look after our customers for the long term, not trying to make a quick sale! We can also provide you with a made to order system of any KW size that matches accurately your requirements, whether you want to just cover your bill or wish to be able to generate surplus to then sell back to the grid……….if you still aren’t sure what that all means then please call us on 1800 797 273 and we’ll be happy to help!
