There is little doubt that solar energy is much cleaner than fossil fueled power sources like coal. Going green is one of the main choices for an off-grid lifestyle, and using a renewable resource like solar power is a perfect way to reduce your carbon footprint. Many homeowners have chosen to avoid paying utility bills and supply charges, seeking the independence, sustainability, and cost savings that an off-grid solar system can provide. Or, due to the remote location of your property it may be cheaper than connecting to the power network.
Off-grid Solar Systems – sometimes referred to as Stand-alone power systems (SAPS) – work by generating electricity from solar panels and using it to charge a battery via a charger controller. That electricity is then converted using an inverter so that it can power your home or business. By storing the electricity in a solar battery, it is possible to run your home exclusively from solar energy, even at night.
For an off-grid solar power system to work effectively it requires a few pieces of equipment. Depending on the size and the scale of your solar power system set-up, we will tailor a system to suit your individual needs.
Photovoltaic (PV) solar panels convert sunlight into electricity. You can use the electricity to power domestic appliances, and store excess energy in a battery. The precise size and production capabilities of your individual solar panel array will depend on the amount of available sunlight in your region, the usable space of your roof, and your energy consumption needs.
In order to convert the direct current (DC) collected by your solar panel array into the alternating current (AC) required to run most of your common household appliances and electronics, your solar power system will also need a solar inverter – sometimes referred to as a solar converter or a PV inverter. For the purposes of an off-grid system, you will likely use a stand-alone inverter, though there are a few options when it comes to set-up
A battery allows your home to continue to run after the sun goes down. Throughout the day, your battery will charge as your panels generate excess electricity. Rather than simply losing out on all of that available solar power, a battery enables you to keep it for use at a later time.
Many owners who use off-grid systems combine them with a generator that can power some of their homes’ electricity needs. These generators are quiet and work integrated with your off-grid system to automatically come on when required, and switch off again when you start producing solar power again.
