Mono-Crystalline Modules

Monocrystalline photovoltaic electric solar energy panels have been the go-to choice for many years. They are among the oldest, most efficient and most dependable ways to produce electricity from the sun.

Each module is made from a single silicon crystal, and is more efficient, though more expensive, than the newer and cheaper polycrystalline and thin-film PV panel technologies.  You can typically recognize them by their color which is typically black or iridescent blue.

Benefits of Monocrystalline Solar Panels provided by Renewable Warehouse:

1. Longevity

Monocrystalline solar panels are first generation solar technology and have been around a long time, providing evidence of their durability and longevity. The technology, installation, performance issues are all understood. Several of the early modules installed in the 1970's are still producing electricity today. Single crystal panels have even withstood the rigors of space travel!

2. Efficiency

As already mentioned, PV panels made from monocrystalline solar cells are able to convert the highest amount of solar energy into electricity of any type of flat solar panel. Consequently, if your goal is to produce the most electricity from a specific area (e.g., on a roof) this type of panel should certainly be considered.

3. Lower Installation Costs

The cost of solar panels is typically around 60% of the cost of a fully installed solar power system, with installation being a significant cost component. Although I haven't confirmed this yet, one installer in Australia (who sells and installs several types of solar panels) has said that some amorphous thin film panels actually need more mounting rails and take longer to install; adding to the overall cost of the system.

4. Embodied Energy

While thin-film solar panels offer a lower level of embedded energy per panel, the fact that more panels are needed somewhat negates this aspect, especially given the extra mounting rails sometimes needed.

5. Other Environmental Concerns

Some thin film solar products uses cadmium telluride. Cadmium is a heavy metal that accumulates in plant and animal tissues. Cadmium is a 'probable carcinogen' in humans and animals.

6. Greater Heat Resistance

Like other types of solar panels, monocrystalline solar modules suffer a reduction in output once the temperature from the sunlight reaches around fifty degrees Celsius/a hundred and fifteen degrees Fahrenheit.

7. More Electricity

Besides producing more electricity per sqm of installed panels, thereby improving your cash flow (from either a reduction in your electrical bill or from the sale of the electricity or in some areas both), for those who are "going green" and are concerned about the environmental impact of solar panels, monocrystalline panels reduce the amount of electricity needed from local power plants,

8. Bankability

A corollary of the durability and longevity of this type of solar panels is that in areas where there is an established track record of performance, we are able to obtain bank financing of up to 90% for our projects, which is certainly a big reason why Germany has the largest installed base of solar panels in the world.

Currently, Peak Solar manufacturers the most efficient photovoltaic systems (monocrystalline solar panels )- with an efficiency of 22.5 percent. In future they will break the world's record for commercially produced solar cells at 24.2% for sure.
