Solar in the Indian Ocean Territories


Want to help the environment or save money on your electricity bill? We install solar systems at Cocos and Christmas.

Residents and businesses who install renewable energy systems in the Indian Ocean Territories receive a large government incentive for installing solar. Eligible systems earn what is called a "feed-in tariff" under the renewable energy buyback scheme, which means you can save a lot of money on your power bill. If you generate more power than you use then you can also get paid for every unit of excess electricity that you sell to the grid.

Solar and Battery Storage

To be eligible to receive the feed-in tariff all new installations need to have batteries installed as part of your system. This requirement for batteries is part of a new set of rules that was recently introduced for renewable energy in Christmas and Cocos. These new rules now match the rules that are already in place in Broome, Exmouth, Carnarvon, and 30 other communities across WA.

The government introduced the rules to minimise the impact of a large number of households generating power from solar and sending it to the grid (if too many households or businesses put energy into the grid it can create technical risks for the network).

Battery storage helps to smooth out the output of your solar system, and is required to reduce impacts to the network. All systems that we install meet the new technical requirements to connect to the grid and receive the feed-in tariff from government.

System Payback

A solar and battery storage system in the IOT will pay for itself much quicker than on the mainland because of the local feed-in tariff. Your exact payback period will depend on how much electricity you use, and the size and configuration of your system.

We will model the predicted amount of electricity that your system will generate, and if you can provide your monthly electricity bill then we can also calculate your payback period and other financial metrics. Our payback models also show how future changes in the price of the feed-in tariff would affect the financial return of your system. 


Let us know which basic system you're interested in and we can give you detailed pricing (the final price depends a lot on whether you want standard equipment or premium equipment).

We are happy to match a quote for an equivalent system from a reputable installer on the mainland. We can also let you know the extra local costs that a mainland installer would have to add. For the IOT you are required to have batteries, battery inverter, cyclone rated equipment, extra engineering certifications, Zentner freight, and all the other local costs etc. We can go through all of this with you - we want you to be able to get a good deal here, and get local support (rather than paying for a team of installers that flies up from Perth and aren't around for support when you need it).

We're a Clean Energy Council Approved Solar Retailer

Island Energy Co is a CEC Approved Solar Retailer and a signatory to the CEC Solar Retailer Code Of Conduct.

Less than 2% of all solar installers in Australia are CEC Approved Solar Retailers, and achieving the status of Approved Solar Retailer is recognition of our commitment to you as a customer. The CEC is the peak body for the clean energy industry in Australia, and they conduct a rigorous process to assess companies for eligibility as an Approved Solar Retailer. Our company and all of our contracts, guarantees, and terms have been assessed by the CEC, and we are now one of the small number of companies that is an Approved Solar Retailer. 

For you, this means you're dealing with a company that has committed to providing the highest standards of solar installation in Australia. We are bound to follow the CEC Code of Conduct, and this code has also been authorised by the Australian Competition and Consumer Commission (ACCC). You can read more about the code of conduct here. All of this protects you as a customer, which we think is great.

All Island Energy Co installers are also CEC accredited for the installation of solar, battery, and offgrid systems.

What you get with every systeM

Guarantees and Warranties

All of our systems come with the following warranties and guarantees.

  • 25 year product warranty on solar panels

  • 10 year performance warranty on solar panels

  • 10 year product warranty on batteries

  • 5 or 10 year product warranty on grid inverters

  • 5 year guarantee on system workmanship

  • 5 year guarantee on system performance

You can read the detailed warranty docs here.

Standard Terms and Conditions

We use a standard set of terms and conditions for all residential and small scale commercial installs. Our contract is based on the official PV Sale and Installation contract template that was written by the CEC and is recommended for all installers by the CEC. This contract describes the terms and conditions that apply to the sale and installation of your system, and includes detailed information about your rights as a customer and the guarantees and warranties that we provide to you.

You can view our standard contract here.

Local Support

We have staff and installers living at Cocos and Christmas, so we understand the local power network and how to integrate your system into the local grid. We also fly regularly between Christmas and Cocos, so you can catch up with us in person.

Because we live in the islands we know what it's like to have your electronic devices break or your shipping delayed. We're also used to working with Zentners for sea freight and the Freightshop / Toll for air freight.

Most importantly, if you have an issue with your system, we are here in the islands to help.

System Components

The main parts of your system are the solar panels (capture energy), inverter (converts electricity), battery and battery inverters (charge and store energy). All of our systems use components from large established companies. 


We recommend the use of high quality components for systems in the IOT (things break up here more than on the mainland). We prefer to install high quality equipment with good warranty support, but if you just care about the cheapest price then we can provide a cheapest tier of products. 


Solar panels all of our solar packages use Tier 1 solar panels from Trina, JA Solar, Jinko, or Canadian Solar. These are high quality solar panel companies, all in the top 5 solar manufacturers globally, have excellent product and performance warranties, and are used in most of the big solar installations around the world. These are all excellent panels, and are recognised as being very high quality panels across the solar industry. If you want to go really high end we can also supply LG panels, but they are more expensive. In general, we recommend Trina, JA Solar, Jinko, or Canadian Solar for the islands. 

Inverters we recommend inverters from SolarEdge and Fronius - both companies make very high quality inverters for domestic, commercial, and large scale projects.For commercial projects with battery storage we recommend SolarEdge, Fronius, and Selectronic inverters for a very high quality system. 

Batteries we offer two tiers of batteries - premium and standard. The cheapest batteries are lithium ion batteries from BYD - a major electric vehicle and battery manufacturer from China. If you want to upgrade to premium quality components you can choose to us use Tesla Powerwall batteries or LG Chem batteries. Tesla Powerwall brings lot of additional features and extra storage size but there is currently limited stock. If you want tried and tested batteries then lead acid or lead carbon batteries are also an option to consider. These are bulkier, and less fancy than lithium ion batteries, but still used in many remote places because of their reliability.
