Off Grid Solar

Target Solar has more than 25 years of combined experience and uses consultants from various fields such as engineering, architecture, business and finance, renewable energy and law. We hold electrical contractor`s license required to be eligible to perform solar related electrical work across Australia. Furthermore, Target Solar only uses CEC accredited solar installers and electricians to perform solar installations and conduct any electrical works.

We work directly with leading manufacturers and our projects ranges from residential solar installation to large-scale commercial solar power stations. If you`re living in a remote area where the supply of electricity can be either irregular or is terribly costly, an off-grid solar power system from Target Solar will allow you to completely be independent of the grid and help you satisfy your energy requirements. Designing and installing an off-grid solar system requires high level of experience and skills to understand customer`s requirement. Target Solar customises each project uniquely as per customer`s need and guarantees that each system will work efficiently.

What is an off-grid solar system?

Off-grid systems, are popularly known as stand-alone systems designed to electrify remote areas where electricity is either unreliable or expensive. Generally, an off-grid solar system or stand-alone photovoltaic systems consists of solar panel either on ground or roof, solar charging modules, a storage battery bank to store surplus energy, a backup diesel generator which is integrated with the solar power system and an inverter which acts as a bridge between different parts of off-grid solar system and manages inputs of energy between them. Usually, the off-grid system batteries are used for energy storage as they may account for up to 40% of the overall stand-alone PV system cost over its lifetime.

Compare to other off-grid solar systems, Target Solar`s modern off-grid solar systems are easy to maintain and come with the latest technology which is fully automated and can be monitored and controlled using a Wi-Fi device. Moreover, electricity produced using an off-grid solar system is much richer in terms of quality as compared to electricity coming to your facility through a power grid. It is simply because you`re utilizing whatever energy you are generating without any third-party interference. Furthermore, using good power quality can further enhance the lifespan of your electrical appliances.

A remotely automated off-grid solar systems are what we call as an `actual hybrid system`. These systems truly are amalgamation of latest technologies designed to automate the switching operations of back-up generators and free of maintenance.

Self-sufficiency of Off-grid solar system

Technically the recommended battery bank autonomy of an off-grid solar system is about 1.5 – 2 days. However, without a generator an off-grid solar system can operate in independently for 2-3 days. This means that during bad weather condition when there is no sun or little exposure, your off-grid solar system can provide enough back up energy for up to 3 days to run all your electrical appliances. The size of the battery bank can be calculated by multiplying the daily kWh usage with the number of days you would like to have autonomy. For instance, for a daily usage of 12kWh, you would need a battery bank with 24kWh usable storage.

Battery Connection

An off-grid system can be connected in difference ways and you may not know the difference between AC and DC coupled off-grid systems. In DC coupled system, the energy flows from the solar panels through the MPPT and gets stored directly into the battery bank. An AC inverter is connected to battery, which converts the DC power to AC from the battery bank during blackouts. Conversely, in AC coupled system an AC inverter is installed which converts the DC into usable AC power, like in a standard grid-connected system. This energy is fed directly to the loads in the facility without having to go to the battery. An additional charging inverter is added for charging and discharging the batteries, this bi-directional charging inverter manages the entire off-grid solar system. Depending on the generator requirement the off-grid can system can also be made automated. For more information, click here.

How is off-grid solar system managed by Target Solar?

For large off-grid or stand-alone solar PV projects, a dedicated project manager is assigned to run the whole project and manage activities such as site inspection, designing, network approval, procurement, installation and testing and commissioning. The practical completion date of each project is dedicated based on the system size and requirements. For large project one of our in-house engineer is allocated to inspect the site followed by the designing of your project.
