Company directors, George Drougas and Nestor Diaz founded Solar Energy Warehouse in November 2019, after 12 months of in-depth research and planning. They both came from a telecommunications infrastructure deployment background and have worked in the Australian Telecommunications industry for a combined period of over 50 years. 

Solar Energy Warehouse has an extensive network of connections with most telecommunications carriers in Australia i.e. Telstra, Optus, Vodafone, TPG and NBN, plus numerous vendor companies such as Nokia, Visionstream, Silcar, Kordia, Huawei and Service Stream, to name a few. More specifically, George and Nestor have both been involved in the deployment of mobile phone networks nationwide and for all major Australian telecommunication carriers.  They have in-depth knowledge of property, design and construction of mobile network site programmes. With this background, they believe there is an opportunity to introduce alternate battery technologies to provide power backup systems within their networks, which rely mostly on traditional lead-acid batteries.

 All Telecommunication companies in Australia are now trialling alternate battery technologies with a view to move to implement this change quickly. The feedback we’ve received from our contacts in the telecommunications industry is that the typical lifespan of lead-acid batteries in their networks is around 7 years, however many batteries have been failing within 3 years. 

 The three main advantages of transitioning to lithium batteries are:

    1. Lithium batteries are more tolerant to heat than lead-acid batteries, hence can run equipment shelters at higher temperatures. This means less reliance on air conditioning, equalling lower power consumption which translates to lower running costs (i.e. shelters could be set to run at a max temp of approx 40 degrees instead of the industry standard of approx 25 degrees)
    2. Space is a premium inside equipment shelters and lithium batteries are more energy dense than older lead-acid batteries. Replacing the existing lead batteries with fewer lithium batteries that can provide the same battery backup power, frees up valuable rack space inside shelters. This enables Telco’s to make space for the new equipment required for technology expansions (such as upcoming 5G); and
    3. Weight is also an issue for sites where equipment shelters are located on rooftops or within buildings with weight limitations on structures (eg suspended concrete slabs), and as lithium batteries are much lighter than lead-acid ones, this is a major advantage.

Solar Energy Warehouse has an in-house technical support specialist who has over 20 years of experience in the design and installation of wind and solar systems for domestic, rural, commercial and industrial applications.  They also have support arrangements in place with electrical engineering consultants who are industry leading PhD-level technical experts in both the telecommunications and renewable energy industries.

Solar Energy Warehouse are able to supply the telecommunications industry with Lithium Iron Phosphate (LiFePO4) batteries and has the technical expertise to support the industry in implementing the new battery technology into their existing systems.
