Energy Efficient

LED Retrofits

Energy efficient lighting projects are an alternate way of implementing energy efficiency in all types of facilities and buildings. Facility owners and operators know that energy costs are significant and that these costs can be reduced by investing in proven and cost effective energy-saving technologies, such as energy efficient lighting projects.


Sun Ray Solar specialise in energy efficient LED lighting projects, from simple change overs to complex retrofits. By implementing our energy consumption and efficiency solutions your organization will significantly reduce its energy costs and become more energy efficient. Projects can be either an outright capital purchase or funded via our EPC program.


On-grid solar power systems are ones you’ll find most commonly and grid-tied, grid-connect and grid-direct systems refer to the same kind of solar power systems. Such a system connects to your energy supplier in case your solar system doesn’t produce enough energy. As a result, an on-grid system does not have to produce all the energy you require. If it ends up producing more energy than required, it sends excess electricity to the grid.

In the absence of adequate sunlight, when solar panels cannot work at optimum levels, you can conveniently draw electricity from the grid to meet your requirements. You can even have a net metering agreement with your electricity supplier, through which you stand to receive compensation for the excess electricity you provide to the grid.

If you opt for an on-grid system, know that it will not protect you from power outages. When there’s a failure at the grid, on-grid systems stop working with immediate effect. This is so the utility provider’s crew can fix the faults without the fear of electrocution owing to power coming through solar power systems.

Off Grid

The use of off-grid systems is more common in regional and rural parts of Australia, where people cannot connect to the grid at all. An off-grid solar power system runs independently of the grid, and it requires enough PV panels to take care of all your power needs. Since homes tend to have higher demands for power in evenings and nights, when production is minimal or absent, such systems normally use batteries or rely on backup in the form of a generator.

Off-grid systems are definitely more complex than their on-grid counterparts, and they offer considerably lesser flexibility. In addition, you have to monitor electrical usage continually and keep the panels’ output below maximum levels because you cannot supply any excess power to the grid.

Components you’ll find in an off-grid system include the following:

  • PV panels

  • Battery

  • Inverter/s

  • Charge controller that keeps the battery from overcharging

  • Electrical safety gear like breakers, fuses and disconnects

  • A system to monitor and balance consumption of energy with production

 * Point of difference with Solafied PPA the customer only pays for the power they use.
No cost Solar System
* Engineered designed Solar System
* System installation
* Daytime power produced from the system is sold to you at a discounted rate from  current retailer. 
* Night time power usage you will be billed by current retailer
* Locked in power price for the life of the contact
* Fully transferable contact.
* System purchase options.
A solar power purchase agreement (SPPA) a
llows you to install solar photovoltaics (PV) without having to pay upfront. SPPAs are available for both households and businesses, but are currently only offered in certain areas of Queensland. How SPPAs work An authorised SPPA provider installs, owns, operates and maintains the solar PV system at your home. In return, you agree to pay for the electricity produced (usually kilowatt hours) by the system for a certain length of time. Generally SPPAs will charge you for all of the electricity generated by the solar PV system. The price you pay per kilowatt hour for the solar power will generally be less than the price you would otherwise pay for electricity you buy from the grid through your electricity retailer. Your connection to the electricity grid is still necessary to provide you with power when the solar system doesn't generate enough power to meet your needs, or when it is not generating at all (such as overnight). Because you receive your electricity from two different sources (the solar PV on your roof and the electricity grid) you will receive two electricity bills: one for the solar power and one for the electricity you use from the grid. SPPAs are long-term arrangements, mostly around 7 to 15 years, and may have penalties or conditions attached for early termination. Some SPPAs automatically transfer ownership of the solar PV system to the householder or business at the end of the term.
