As we know from the Solar electricity applications section, the way in which the electricity is used will determine the profitability and viability of a PV installation.
- Domestic PV installations below 6kW (single phase) and 11kW (3-phase) in domestic settings, fall into the microgeneration scale category :
- How do I go about organising a tie-in/connection to the grid?
- As a domestic producer of electricity, Will I get paid for electricity exported to the grid?
- With regard to the grid connection process itself, ESB Networks should be contacted, in particular, see the following section of their website: http://www.esb.ie/esbnetworks/en/generator-connections/gen_connection_export.jsp
For further information on microgeneration, please see the Solar electricity : Microgeneration section.
- Non-domestic PV installations or installations not falling into the microgeneration category (i.e. above 11 kW) should be planned with the following in mind :
With regard to getting payment for power supplied, then electricity suppliers should be contacted to see if any of them will offer a power purchase agreement (i.e. to see if they are prepared to buy the electricity produced by the generator) notice that the grid connection and electricity payments are separate items.
REFIT is a scheme which assures long term security for electricity suppliers when purchasing power. This has not been formalised yet for this year, but suppliers are more likely to buy power from renewable generators when it is in place.
