What is Off-grid System & How Does It Work?

Though grid-tied solar panel systems are more popular among Singapore homeowners, many are choosing to go off-grid instead. And we’re not surprised — cutting ties with the utility company is certainly appealing, and who doesn’t like the idea of freedom from monthly electricity bills?


However, installing a stand-alone solar array isn’t the right choice for everyone. Before you decide to take that route, consider the following.


OFF-GRID SOLAR PANEL SYSTEM DESIGN CONSIDERATIONS


If you don’t plan on hooking your solar panels up to the utility grid, the PV system must be capable of completely meeting your household electricity needs. In addition, it will need to be able to handle the inevitable fluctuations in energy production and usage.


With today’s advanced technology, a stand-alone solar energy system can generate all of the power you need. But if budget is a concern, you may want to increase your household efficiency and reduce your energy consumption before embarking on installation.


COST CONSIDERATIONS FOR AN OFF-GRID SOLAR PANEL SYSTEM


Regardless of whether you decide to embrace energy efficiency, your PV system will require certain components. Just as with a grid-tied solar array, yours will have solar panels, a string inverter and PV mounting system.


Your PV system will also need to include a bank of batteries to store electricity – otherwise, you will only have power when the sun is shining. Furthermore, to regulate the flow of energy between the batteries and the solar panels and to prevent overcharging of the batteries, the PV system must have a charge controller.


With the additional components required, installing a stand-alone PV system can cost significantly more than going with a grid-tied solar array. However, if your property isn’t already connected to the utility grid, the opposite could be true – extending the lines might actually come at a higher price than going off the grid.


LIVING THE OFF-GRID SOLAR LIFESTYLE


The off-grid lifestyle has its own unique challenges. When you first start out, you might experience spotty internet service, for example, or you could end up with water shortages.


To discover whether you’re ready go off the grid – and to get an opportunity to experience the lifestyle and brainstorm potential solutions to the problems you may face – consider renting a home with a stand-alone PV system. You can find one through a simple internet search, or browse one of the rental search sites dedicated to self-sufficient properties.
