Photovoltaic Solutions

We believe in fitting the correct system to suit you, your budget and your expectations. The purchase of a renewable energy system is a large investment and should be carefully considered.

We supply and install custom built systems with NO hidden costs!

Most companies offering discounted prices overstate the performance of their “off the shelf systems”, and never take into account your daily power consumption.

Your solar system is a renewable resource and does not add to the CO2 emissions into our atmosphere – clean, and green energy“.

Do your research and choose an accredited Clean Energy Council installer, whom you feel you can trust. Would you buy a TV over the phone without knowing the brand, model, specifications or whom you were dealing with?  So why spend thousands of hard earned dollars on a solar system without some form of due diligence!!  Remember your system is expected to last for 15 years PLUS. We offer the complete service!  We cover all aspects of energy efficiency. This includes education on how to become more energy conscious and how to benefit from your Solar System to significantly reduce your power bill.

Solar is the most common type of renewable energy system and the three main types of solar modules within the industry today are: Amorphous (Thin film), Mono-crystalline and Poly-crystalline.

 

So what’s the difference?

Short Energy Payback Period

By using less silicon material, THIN FILM solar panels are manufactured using less electricity, hence they have a shorter Energy Payback period than conventional panels. After the first year, each THIN FILM panel has produced as much energy as was required to manufacture the panel, this energy is known as embedded energy.

High Temperature Performance

Most solar panels lose performance as the ambient temperature increases- a big problem in Australia. THIN FILM panels typically produce 10% more during the heat of the day due to their higher operating cell temperature – this adds up significantly over the life of the system.

 ‘Dim Light’ Performance and Positioning

THIN FILM panels have a better ‘dim light’ and ‘off axis’ capability than most other panels. Off axis refers to positioning other than True North, and a shallow tilt angle. As a result, for an equivalently rated system, a THIN FILM panel can deliver around 10% more energy than most other systems in the morning and afternoons.

Shade tolerant

Many solar panels lose 25% or more of their performance due to shading and dirt on the panel. THIN FILM panels only lose an amount corresponding to the shaded or dirty area. This translates into better real world performance over the life of the panel.

 Disadvantages

Thin Film panels generally require roughly twice the number of panels as the equivalent poly or mono systems. Therefore twice the roof space, twice the racking system and fused string protection may also be required. Consequently the installation is more labour intensive. Transformer based inverters can only be used.

Mono-crystalline solar panels have been the go-to choice for many years. They are among the oldest, most efficient and dependable of technologies.

Each module is made from a silicon crystal cylinder and laser cut into wafers between 0.2 mm & 0.4 mm thick and electrically bonded with thin metal strips.

They are generally considered the workhorses of the solar power market, and most people will choose mono-crystalline panels due to their ready availability. These panels are easily identifiable, made up of uniformly stacked rounded cells. The process of making them is complex and expensive, but with large scale production they have plummeted in price.

You are buying efficiencies of 15%-18% in comparison to poly-crystalline and amorphous panels. This percentage is the rate of conversion of solar energy to electricity. If roof space is limited, mono-crystalline can be the best type to use, as more power per square meter can be generated.

The average 180 W panel is about 1500 mm in length, 850 mm in width, over 35 mm high, and weighs 15 kg. Mono-crystalline panels have a manufacturers output warranty of twenty-five years, making them an excellent long term investment. Panel output has now increased with no lessening in efficiency.

Mono-crystalline solar modules suffer a reduction in output once their cell temperature reaches above 45°C, at an ambient air temperature of 25°C. This translates to a decrease in output with every increase in degree of temperature, and is known as the temperature co-efficient. This is slightly higher than the reductions in output experienced by poly-crystalline cells, but they still need to be factored into the calculations and design of any solar power system.

Mono-crystalline and poly-crystalline systems require a Northerly aspect, at a tilt angle of approximately 28º in Victoria. On a flat or shallow pitched roof,  a raised racking system will be required to maintain a high output and to allow rain to wash off any dirt and debris. A manufacturer’s engineering certificate and installation procedure must be presented with all the other forms and certification. Racking manufacturers do not supply engineering on a raised system.

poly-crystalline cell is made from a block of cast silicon. Poly-crystalline solar modules are only slightly less efficient than those made from a single crystal (mono-crystalline). They cost less in the manufacturing process in comparison to monocrystalline modules. They have less embedded energy and a shorter energy pay back period.

With current modern manufacturing techniques, these panels are now regarded as having parity with their mono-crystalline cousins.

Generally poly-crystalline panels have a conversion efficiency between 13% and 16%. This is the percentage of energy converted by sunlight into electricity.

Poly-crystalline panels appear as a solid block of crystalline silicon, this differentiates them from the single cell appearance of mono-crystalline modules.

Every home and business is different and we cater for all our customer needs. Whether it is the positioning of the panels or the location of the inverter, we listen to our clients and strive for the best outcome.

We endeavor to create the optimal solution, maximise system performance for complete customer satisfaction.
