Thinking about switching to solar? You’re not alone. Thousands of households across Melbourne are choosing renewable energy to reduce bills and support a greener future. But once you’ve decided to go solar, another big question arises — should you install single glass or double glass solar panels?

At Climate Green Melbourne, we make solar simple. Here’s everything you need to know about these two popular panel types and how to choose the one that suits your needs.

Solar in Victoria: Why Now Is the Perfect Time

With increasing sunshine hours, attractive VEU rebates, and rising electricity prices, Victoria is one of the best places in Australia to invest in solar. From city rooftops to regional homes, solar panels are helping Victorians save money and reduce their environmental impact — and the trend is only growing.

But to get the most from your investment, it’s important to understand the types of panels available.

What Are Single Glass Solar Panels?

Single glass solar panels, also known as monofacial panels, are a familiar sight on many rooftops. These panels have a single layer of glass on top and a durable backing layer underneath.

They’re lightweight, easy to install, and are an excellent fit for homes with limited space. Their sleek black appearance blends well with most rooftops, and they offer strong energy output per square metre. If you're looking for a proven, space-saving solar solution, single glass panels are a great option.

Of course, like any technology, they have limitations. Their performance can be affected by shading, and the polymer backing may be more prone to long-term wear and tear compared to glass. Still, for most residential needs, single glass panels do a fantastic job.

What About Double Glass (Bifacial) Solar Panels?

Double glass solar panels are a newer, high-performance option. They have glass layers on both sides, allowing them to absorb sunlight not just from above, but also from reflections off surfaces below — like concrete, white roofing, or even snow in some regions.

This dual-surface capture means higher overall energy generation, especially in sunny and reflective environments. They’re also built tough — with excellent resistance to moisture, weather, and chemical exposure, making them a smart long-term investment.

That said, double glass panels tend to be heavier and require more careful installation. They’re also slightly more expensive up front. But in the right setting, their energy output and durability can more than justify the cost over time.

How Do You Choose the Right Type?

The best panel for you depends on your property, your goals, and your budget.

If your home has limited roof space and you're looking for a sleek, cost-effective system, single glass panels may be ideal. They deliver excellent performance in tight spaces and are easier to install.

If you have a larger roof area or open surroundings with plenty of reflected sunlight — such as light-colored surfaces or open yards — then double glass panels could be the better choice. Their ability to generate more electricity over time can offer greater long-term savings.

No matter your choice, both panel types are eligible for Victorian Government rebates. And at Climate Green, we’re here to help you take advantage of every available benefit.
