How to Store Energy from Commercial Rooftop Solar Systems

Going green and saving running costs is a priority for many Australian companies, and our sunny weather means that installing commercial rooftop solar systems is a popular choice for businesses and industrial sites. Solar panels are only one part of the equation, however – the other critical ancillary equipment is energy storage systems for the additional solar energy output from the panels themselves.


 Why are solar energy storage solutions essential ancillary equipment? 

 There are several benefits of installing an energy system to support a commercial rooftop solar equipment, including:
  •  Meeting electricity demand more effectively: Energy consumption isn’t consistent through the day and may change between very high demand (for example, through the middle of the day) to almost no demand at all (for example, the early hours of the morning), depending on your organisation’s needs. A battery system allows excess energy to be stored so that when demand increases, the building draws on stored solar rather than resorting to the grid. 
  • Allowing businesses to achieve a fully off-grid status: If the aim is to move your organisation off the grid entirely, then energy storage is a must-have. Solar panels can only produce when they have exposure to the sun, so in cloudy weather or at night your business will have to rely on the grid for its power. 
  • Reduce wastage: One day might be full sun where your panels produce a significant amount of excess power, but if the demand isn’t there it simply goes to waste. Battery storage systems allow you to hold this energy in reserve for when demand increases, or weather is poor. 
  • Keep systems running during grid outages: Power outages cause organisations to grind to a halt, but not if your commercial rooftop solar system has a battery storage system supporting it. Solar panels do require some electricity to be active, but your battery system can supply that and allow you to access sufficient operational power without relying on a generator. 
  • Export power for profit: Excess power can also be sold back into the national grid through solar feed in tariff. The rebates you can receive are determined by regulations and differ according to state and retailer 
 Solar battery systems are making an impact in Australia 

 According to the Climate Council, it could take as little as 3 years before as many as half of all Australian homes have solar and battery storage – and commercial enterprises are showing a similar level of enthusiasm. Allowing homeowners and organisations greater control over their power bills and operating costs, this ancillary equipment is dropping rapidly in cost even as the technology becomes more efficient and durable. Even the mammoth $96 million big battery in South Australia’s Hornsdale Power Reserve should pay itself off in just a few years, according to Tesla.

A Guide to Different Types of Commercial and Industrial Fluid Chillers

Fluid chillers in Australia are used in a variety of different industries, including the food and beverage industry, manufacturing, pharmaceutical, and chemical manufacturing sectors. Running on electrical power , this industrial equipment provides critical cooling and temperature control, and utilizing the right type of fluid chiller will optimize productivity, improve efficiency and lower operating costs.  Types of Industrial Fluid Chillers in Australia By Condenser Type   Air-cooled chillers: Air-cooled fluid chillers use the air in the environment around them assisted by fans to remove heat from the refrigerant in the condenser. It then runs the refrigerant back through the system to provide cooling. As a result, the air around these chillers is usually very warm and they are not recommended in applications where this will be an issue. These systems are often portable, available in both large and small-scale commercial versions, are relatively affordable a...

Why Cat Generators Are One Of The Best

We are big fans of Caterpillar generators.  They are better known as Cat generators .  Leaders in the generator industry, you can never go wrong with a Cat rental .  With so many kinds of generators, different models all running on different fuels, it's a big world.  Generators are excellent for energy storage .  We use them in times of crisis, as back-up options and for rural purposes.  There are many uses for a generator, it can be quite difficult when it comes to choosing the right one.  We recommend the Caterpillar generators for several reasons, as outlined below. Generators aren't toys We don't research a Cat rental for fun.  Cat generators are not toys and not for playing.  That said, some may say generators are like toys for the grown men.  Generators work to provide an energy storage bank so that when they're needed, energy is available.  Generators are an expensive item that, if looked after, can last for ...

Tips for Storing Your Backup Generator

Backup generators  are very useful equipment for homes, businesses, and industrial sites, providing clean, reliable power when the grid isn’t available. However, they’re not always in use, so it’s important that they’re stored correctly until they’re needed again to ensure that they stay in perfect working condition.  Here’s some advice from our team who  hire generators  and sell  diesel generators  for commercial, residential, marine and industrial use.   Short-term storage for diesel generators   If you know that you’ll likely require your generator throughout the next few months but that it may sit idle for a week or so in between use, then storage is a relatively simple thing. Simply clean any dust or debris off the unit after use and store it somewhere with easy access where it is protected from the environment. Keep in mind that diesel starts to deteriorate after about 10 days, so if you leave it for more than 3 weeks ...
