Pros and cons of off-grid vs hybrid

If you’re thinking about long term sustainability and energy efficiency - you’ll want to explore the ins and outs of  renewable energy system. If you're considering solar, you next need to decide between the three types of solar systems: off-grid, grid-tied or hybrid. Choosing the right system means minimising power costs and good return on your investment in the long run. 
While one system type is perfect for some homeowners, it could be bad for others. All systems are beneficial in their own ways, so knowing the facts and benefits of each will help you decide which is right for you. 

In this blog, we’ll dive deeper into the pros and cons of our most common system: the hybrid set-up, and compare it with going off-grid.

Hybrid solar systems: What is it, and what does it mean for homeowners?

A hybrid solar system is grid-tied with battery storage. They come with a special ‘smart’ inverter that can transmit direct current (DC) power to and from your batteries, and channel alternating current (AC) power between the grid and your home when necessary.

Hybrid systems allow for full control over your power, while keeping you grid-connected in case of emergency. 

Key benefits of hybrid systems

Here are some of the perks of a hybrid solar system:

1. You’ll use less grid electricity than you would with a traditional grid-tied system. While hybrid setups are grid-tied, they come with solar battery storage, which means you can maximise consumption of the power generated from the panels.
2. A hybrid system is possibly the most expandable, future-ready home solar setup. With some customisable hybrid systems, you can expand capacity by buying more panels or batteries. Hybrid systems may also be compatible with newer solar technologies — for example, an electric vehicle (EV) might function as one of the ‘batteries’ in a hybrid setup. 
3. For even lower costs, you can use a power management system. These technologies can automatically optimise your power usage. (For example, larger appliances like dishwashers can be switched on during peak daylight hours.) The result: bigger utility savings and a quicker ROI.

1. There’s a lot to install upfront, making the initial investment bigger. While you can budget for a smaller battery bank than with an off-grid setup, the cost still needs some thought. Specialised equipment, such as a smart hybrid inverter, adds to the price tag. 
2. Lots of space might be necessary for the required parts. With grid access, you’re likely not in an isolated rural area - even so, you’ll need space for hybrid solar equipment, including the battery bank and inverters.

Off-grid - what is it, and what does it mean for homeowners?

An off-grid solar system is a solar installation that isn't connected to the utility grid. This means you have to rely on your solar panels to generate all your power, all the time.

With an off-grid system, solar batteries are necessary for storing energy. It’s also smart to budget for a backup generator for extended periods of bad weather in case solar battery storage runs out.
