Testimonials
See what our customers have to say about their installation experience with OffGrid WA

Jason and the team at OffGrid WA have installed a system at our flagship location in Mount Lawley.
A brilliant team of technical experts led by Jason – who is a top bloke – our experience has been positive and professional. The standard of service has continued into ‘after sales’ with the team on hand to assist with support and questions.
Support a local WA company. We highly recommend getting in touch with OffGrid WA if you are looking for off-grid solar and battery solutions.

Just wanted to say that guys from OffGrid WA who worked on my house today were punctual, professional and polite. As someone who renovates a lot it’s a pleasant change to deal with a company that does what they promise, when they promise – and do a great job. Good work and thanks again

Our farm had no power but the option to connect to the grid was very expensive, so we explored off grid battery and solar. Not only did Jason find the right solution, he explained all the options to help me choose the right system for my needs. It ended up being about half what connecting to the grid would be – and even better, no power bills ever!

We had our old solar panels replaced and couldn’t be happier with the result. They system works really well, they were very professional and great value.

We’ve used a solar system on our business premises for the last few years. Jason and the team completed a review of our existing system and found an easy way that could save even more money by adding a few extra panels. Highly recommend solar (and Jason) for any business or home – our electricity bill is not half what it used to be.

We had a 19.8kwh battery installation of LiFePO4 lithium batteries to our existing 5KW PV system.
They seem to not only enjoy the job but actually enjoy working with eachother which is a credit to Jason.
