Frequently asked off grid power questions

What is off-grid power??

When you are off-grid you are not reliant on the public power distribution networks in WA such as Western Power and Horizon Power. You are producing your own power supply away from the power grid using renewable energy such as solar, wind and hydro plus using batteries such as lithium and lead acid as well as usually having a back up generator.

At Statewide Power we have all the experience, expertise and top quality Australian made products that are required to install an off-grid solar system in all kinds of residential, commercial, agricultural and mining installations.

How much does it cost to go off grid?

To go off-grid, you are going to need the following: Off Grid Inverters, lithium batteries, large solar system and backup generator. In total, you should expect to spend a minimum of at least $25,000 if you plan to live entirely off the grid. System sizes and prices go up from there and can reach over $100k.

However, the most common size is $35-$50k for a regular 4/2 home with 2 adults and 2 kids. We custom design system sizes to suit your load, and all of our systems are expandable at a later stage by adding more batteries and panels when your power usage increases..

Do you sell off-grid solar systems for residential homes?

Living in remote areas of WA means you may rely on solar energy to run your home, although there are plenty of customers who prefer to go off the grid just so they can become independent, mitigate grid power failures and save money on electricity, whilst caring for the planet. A 10KW solar system is usually large enough to provide for average households depending on your energy consumption but we also have smaller solutions for weekenders or granny flats and even bigger systems to help larger households, farms and remote stations go completely off the grid.

How many solar panels do you need to go off grid?

Households in Australia have an average daily electricity consumption of 12kWh and 16kWh. As a rule of thumb, a 1kWh solar power system can generate around 5kWh of energy at Perth’s latitude at optimal conditions (which isn’t always guaranteed). Different locations produce different daily averages however as I’m sure you can understand, it all depends on the sun shining. This means that you will need either a 4kW or 6kW solar system if you wish to cover your daily electricity usage. But if you want to be fully independent of the electricity grid, the larger 10kW system is recommended as a minimum. Off grid systems are designed for the winter months, we aim to only have your gen set starting 2-3 times a week in winter (if at all) meaning during summer, you will have an abundant supply of power so you can run your air conditioner all day without worrying about draining your batteries.

Do you sell commercial off grid systems?

Off-grid power solutions for businesses are a perfect solution to control your costs.

Off-grid solar systems are great for businesses in remote areas, businesses that want to reduce their operating costs and for those that want to operate as environmentally friendly.

Going off the grid with your business has many benefits. For example; you can enjoy a stable and predictable monthly repayment for your solar system instead of having to guess your monthly power operating costs.

Statewide Power offers off-grid solar systems in Western Australia for small to large businesses, farms, remote stations, resorts and mining operations.

Which is better on-grid or off grid solar?

On-grid means your solar system is connected to your local power utility's GRID. ... Being grid tied is beneficial because you don't have to buy an expensive battery back-up system to store any excess energy, however you pay for the power you use.

Being off-grid means you are not connected in any way to your grid's power system or utility company, you will need batteries and a back up gen set.

With the price of lithium batteries coming down over recent years it is now affordable to go fully off grid, with most systems paying for themselves between 8-12 years and system lifespan of 20-25 years (if maintained and used correctly)   That's 8-12 years of FREE power!

What is the difference between off grid, on grid and hybrid solar power systems?

OFF GRID = No connection to the power grid at all. You will have your own panels, batteries and generator. You are independant of the grid and any issues any price increases that may arise with it.

ON GRID = You are connected to the grid, your panels produce power when the sun is shining, it gets consumed in your home first and whatever is not consumed gets sold to the grid (at a very reduced rate) then when the sun goes down, you buy that power back again.

HYBRID = You are connected to the grid, your panels produce power when the sun is shining, it gets consumed in your home first and whatever is not consumed gets stored in your batteries. When the sun goes down your batteries are used up and when they are flat you then import power from the grid.

Can I Expand My System Later?

Whether you can expand your battery capacity later is entirely dependant on the type of battery system you choose. In most cases the solar component of your power system can be easily expanded (within utility restrictions if you are grid-connected or design rules for off grid), and it’s the battery capacity that can sometimes be tricky or expensive to expand.

Systems like the Power Plus Energy or Gen Z are extremely easy to expand on – and are designed to be modular. We can even ship the extra batteries straight to you directly and we are able to reprogram your system online, meaning no site visits and more savings for you.

However, if the original product is no longer available due to battery technology changes then this could be more difficult than expected in the distant future, so you should try to make sure you choose the correct system size in the beginning..

Can I Add Batteries To My Existing Solar Power System?

Yes, you can. But there are a few things to consider.
Some battery systems may only compatible with a select few inverters. So we would need to find out what your existing inverter is, and then advise which battery systems are compatible.

However an AC coupled battery system like REDBACK TECHNOLOGIES is able to be added to any solar system. And has the added function of being able to power some loads during a blackout.

Going Off-Grid Makes Financial Sense Long Term
The initial investment costs can be a bit intimidating at first, but the savings you'll receive in the long run make it a financially sound choice; an off-grid homeowner can save an average of around $20,000 in over 20 years in most cases.
