Solar panels – solar PV options

Choosing your solar PV’s

There are a number of options when selecting a solar panel to suit your home or business and its requirements. The most common types installed globally aremonocrystalline PV and polycrystalline PV, which are commonly used thanks to their availability, cost effectiveness and efficiency.

Here’s a brief outline of each type, all of which are available from Energy Gain UK.

Monocrystalline Silicon PV is the most efficient type of silicon PV, providing efficiencies of between 13-17%. It uses hexagonal-shaped slices to enable more of them to be fitted within a single unit. As the unit requires more involved manufacturing processes to generate its level of efficiency, these tend to be slightly more expensive than alternatives. But their efficiency means they can often provide a reasonable payback in a relatively short space of time.

Polycrystalline Silicon PV panels offer efficiencies of around 11-15%, and are made up of square blocks of silicon that have a typically blue appearance. The reason for the colouring of these panels is to ensure the panel reflects as little light as possible, absorbing higher quantities than many equivalent PV panels.

Amorphous Silicon PV panels provide a much lower efficiency rate of around 6 – 8%, and use cells that are commonly found in pocket calculators. This type of solar panel is not always suitable for residential and commercial properties, but there are certain applications for which it performs well. Its multi-layered format allows the panel to react to different frequencies of light, and it uses less silicon that many other products on the market, making its manufacturing cost slightly cheaper overall.

Hybrid PVs use a clever combination of solar PV technology to generate a more efficient panel than more common products on the market. These efficiencies are usually above 18%, but they do tend to cost more than conventional panels.


Selecting the right PV panel for your requirements

If you’d like more help and advice on which is best suited to your home and lifestyle, please call us or send an email enquiry, and one of our technicians will be happy to help.

“Energy savings are scaled according to energy use, the more you consume, the greater the savings you are potentially going to make.”

Considerations when selecting your solar panel:

Q. How much energy would you like to produce?
A. It’s often a good idea to check back over previous energy use to establish what your energy consumption is on a yearly basis. This will help give you a good indication of how much energy you’ll need to produce.

Q. How much roof space do you have available?
A. Once you’ve discovered how much energy you’ll need to produce, Energy Gain UK can provide you with detailed information about how large the panels would need to be to generate the desired amount of electricity.

Q. How much will the system cost?
A. There are a variety of systems available to suit a wide range of budgets. The less efficient systems do tend to be slightly cheaper, but are often more than adequate for a variety of business applications. The more efficient units come with a higher price tag, but generate more electricity over their lifetime.

Q. How efficient does your system need to be?
A. As described above, there are multiple systems available. Energy Gain UK can advise you on which system best suits your needs and budget.
