Solar Photovoltaic Systems

Solar photovoltaic systems, commonly known as PV solar panels work by producing electricity to run your household appliances and lighting through a process called ‘photovoltaic streaming’, ‘photo’ referring to light and ‘voltaic’ to electricity.

The electricity is produced via cells, multiples of which become ‘panels’ which are attached to your roof or walls. Multiple panels are known as an ‘array’. The cells are made up of semi conducting material, usually silicon, and an electric field is created across the layers when light shines through them. The stronger the sunlight, the more electricity is produced, although photons can penetrate clouds, so even on an overcast day, energy can still be collected. In full sunlight the cells’ strength is measured n kWp (kilowatt peak).

The DC power collected (Direct Current) is converted into alternating Current (AC) via a power inverter. It is now the same standard provided by the National Grid. The AC electricity is connected to your home via the solar power collector and is linked to your electric meter and fuse box. Your electric meter will monitor how much energy you are using and how much is sold back to the Grid * See Benefits below.

PV cells are available in varying sizes, colours and shapes to suit your particular requirements, transparent panels that can be used on glass/conservatories to small grey tiles that resemble roof tiles.

The Benefits of Solar Electricity

• Reduces your electricity costs – Once installed, your bills will be greatly reduced as sunlight is free!
• Reduces your carbon footprint – No harmful C02 emissions
• * Any excess electricity can be stored in batteries for future use if you are not connected to the National Grid
• If you are connected to the National Grid, any excess electricity produced beyond your requirements can be sold back

Is Solar Electricity the way forward for me?

• Yes, if you have a roof or wall that is exposed to sunlight all day (within 90 degrees of south)
• Yes, if your roof can withstand the additional weight of the panels
