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.
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:
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
