Off-Grid Solar System Installation

Embrace true self-sufficiency and independence from the grid by harnessing the power of the sun with Poslec to generate electricity for your home or business.

Tired of relying on the grid for your energy needs or paying an ever-increasing daily standing charge? Take control of your power supply with a Poslec off-grid solar system. 

An off-grid solar system allows you to generate, store and manage your own power using solar panels and batteries for later use. You can live completely independently from the grid, even in remote areas, and enjoy the benefits of renewable energy. Plus, you’ll save money on your energy bills and reduce your impact on the environment.

Off-Grid Solar Systems

Off-grid solar systems offer a sustainable and independent energy solution for those living in remote areas without access to the grid. It comprises solar panels, a charge controller, batteries, and an inverter that work together to convert sunlight into usable energy.

The solar panels are responsible for collecting sunlight, which is then converted into direct current (DC) electricity. The charge controller regulates the amount of electricity flowing into the batteries and prevents overcharging, which can damage the batteries. The batteries store the energy generated by the solar panels, and the inverter converts the DC electricity into alternating current (AC) electricity, which can be used to power things like household appliances.

Benefits of Installing an Off-Grid Solar System

With an off-grid solar system installation, home or business owners can avoid the soaring costs of utility bills. 

Another benefit of an off-grid solar system installation is the reduced environmental impact: You can be sure that you’re contributing to a more sustainable future. 

Off-grid solar systems also require minimal maintenance and have a longer lifespan compared to traditional off-grid power sources, making them a more practical and cost-effective solution in the long run.

Government Rebates and Incentives

In Australia there are financial incentives for households that install off-grid solar systems, the most popular being the Small-scale Renewable Energy Scheme (SRES), which provides a rebate for the installation of small-scale renewable energy systems, including off-grid solar systems. This scheme can reduce the upfront cost of installing a solar system by thousands of dollars.

In addition to the SRES, homeowners may also be eligible for state-based incentives and rebates. For example, the Victorian government offers a Solar Homes Program that provides rebates for the installation of solar panels and batteries. The rebate amount varies, but it can cover up to 50% of the total cost of the system. These incentives and rebates make off-grid solar installation more accessible and affordable for homeowners.

Yes you can, however, you may need to make some adjustments to your power usage and consider purchasing energy-efficient appliances to maximise your system’s performance.

The typical payback period for an ‘on-grid’ solar panel system installation is between 5–10 years. Off-grid solar systems require a bigger initial outlay, so it may well take longer to recoup the cost of an off-grid solar system. However, this can vary depending on the size of the system, energy consumption and the cost of electricity in your area. Contact us for a full assessment of your payback period.

The excess energy can be stored in your battery array for later use.

Yes this is possible, but it depends on the system’s original design and the availability of additional space for new panels and batteries. It’s important to plan for potential expansions during the initial installation.
