Solar Photovoltaics (PV) capture the sun’s energy using photovoltaic cells which convert the sunlight into electricity, to power your home, business or farm. Importantly the technology relies only on daylight to produce electricity, therefore is effective all year round.
By installing a Solar PV energy saving solution you see a reduction in your energy usage which translates into energy cost savings and you may qualify for a government incentive, Northern Ireland Renewable Obligation Certificates (NIROC Scheme). Solar Panels are a low maintenance, high return on investment solution.
The NIROC Scheme entitles you to claim Renewables Obligation Certificates (ROCs) for every megawatt hour of electricity you generate. Under the current scheme customers will be paid 3 ROCs for every unit of clean electricity produced from the solar panel(s) on your roof.
Importantly the NIROC scheme and number of ROCs paid per unit of clean electricity produced is due to change this Autumn 2016, so NOW is the time to install a PV System to benefit from the current payment scheme.

How does it work?
- A solar PV panel consists of cells of one or two layers made from a semi conducting material like silicon.
- When light shines on the cell it creates an electric field across the layers, causing electricity to flow.
- The electricity flows through a cable and is collected at a central point often located in your roof space.
- The electricity is then converted from a direct current (DC) to an alternating current (AC) and carries on into your home, business or farm for you to use.
If you don’t use all the electricity that you have generated it will be fed into the National Grid automatically.
How much does it cost to install a Solar PV system?
Costs depend on the size of the system and how it is mounted.
How much energy will it generate?
Five main factors guide how much energy a solar PV system will generate:
The total size of the PV array.
The latitude of the location.
Which direction the PV panels face.
What slope the panels are mounted on.
Anything which shades the panels.
As an example south facing roof mounted 1.0kWp PV array in NI should generate approximately 850 kWh per year.
How much do I get paid for my generated energy?
Under the NIROC’s scheme (Northern Ireland Renewable Obligation Certificates) customers will be paid 3 ROCs for every unit of clean electricity you produce from the solar panel on your roof, currently customers will earn around 12.7p (09-08-2016) for every unit of clean electricity produced, whether you use it in your home or export it to the grid. This is paid every year, TAX FREE for 20 years if you are a home owner.
Importantly the NIROC scheme and number of ROCs paid per unit of clean electricity produced is due to change this Autumn (2016), so now is the time to install a PV System to benefit from the current payment scheme.
Do I need planning permission?
Most properties won’t need planning permission but it’s always a good idea to check with your local planning department before you begin the work. Find out more at Planning NI
How does it connect to the grid?
Your solar PV panels will be linked together and connected into an inverter which converts the DC power from the solar PV panels into mains voltage compatible AC.
