How it all works

  • The sun delivers more energy to earth in an hour than is used worldwide in a year. We can harness this energy by using solar technologies and thoughtful building design
  •  Generates electricity for use.
  • Typically consists of an array of PV panels, cabling and an inverter, with monitoring devices and protection.
    The PV system should be sized to the typical daytime electricity demand.
  • Energy storage via heating hot water in your tank (water diverter) and/or battery storage can be considered to increase self-consumption.

How We Work

How Solar PV Works

Industrial engineering is a branch of engineering which deals with the optimization of complex processes, systems, or organizations. Industrial engineering is a branch of engineering.

Solar Panels

Solar Panels installed on your rooftop absorb the sunlight and convert it to direct current (DC electricity), which is then sent to your solar inverter


Inverters convert the direct current (DC) electricity to alternating current (AC)electricity. DC power is produced from the solar panels and AC power is the power used in your premises.


A solar battery allows you to continue powering your home with renewable solar energy during the evening and at night when the solar panels are unable to generate energy. Solar PV panels convert solar energy into usable electricity and, more often than not, they are producing more electricity than can be used.

PV hot water diverter

A PV hot water diverter takes the excess energy been produced from your PV system and converts this energy to heat your water.

Electric Vehicle Charging

There is a grant available for the purchase and installation of an Electric Vehicle charging point in your home. In order to avail of this €600 grant, you must own an eligible electric vehicle. TriNRG also provide electric vehicle charging stations for business premises, Electric Vehicle charging points can be synchronised with your PV system to maximum energy production and efficiency.”

Fused Board

The electricity from the inverter goes to the fuse board in your premises and is used throughout your premises in the same way as electricity from the grid

Energy Meter

The energy meter is used for production, consumption, and import/export monitoring. The meter has high accuracy readings, from a wide selection of current transformers (50A – 1000A) that support residential and commercial installations.


A solar monitoring system can help make you more aware of your PV system’s performance. It offers information about energy consumption and generation, optimising energy usage, and damage to your solar system.

Energy Storage

  • Solar PV panels, especially when combined with energy storage systems like batteries, contribute to the overall reliability of energy supply. Excess electricity generated during the day by solar panels can be stored for later use. This has implications for smoothing out the intermittency of solar power, ensuring a more consistent energy supply, and supporting grid stability.
  • Deep-cycle lithium-ion batteries are the most popular type of solar battery for residential solar applications. These batteries are durable and require little to no maintenance. They also come with a higher energy density and depth of discharge. Domestic battery storage is a rapidly evolving technology that is typically used alongside solar photovoltaic (PV). It allows surplus electricity generated by solar panels to be stored for later use, rather than exported to the National Grid.
  • If you have solar  PV,  you  can  generate plenty of electricity when the sun is shining. But on overcast days you’ll make less. This generation pattern often doesn’t match up with when households want to use electricity – it’s at night when you want the lights on and to use appliances like a dishwasher or TV.
  • If your solar panels generate electricity and you don’t use it, it ends up  being  fed  into the National Grid. This is where battery storage comes in. If you can store the electricity generated during the day, there is less need to consume it when the sun is shining, and you’ll use more of the power you generate and save money.
  • In addition, some batteries can now export and import electricity directly into the grid, helping to balance national demand and supply issues, and also reducing carbon emissions at peak times. New methods to engage in energy trading are emerging, like selling electricity locally to neighbours or to a micro grid or being part of an  international ‘battery community’.
  • TriNRG will assess your electricity usage and design a battery storage system that suits you.
  • Battery storage is developing fast. Storage capacity in Ireland (domestic and non- domestic) is expected to  increase significantly over the coming years.
  • The technology is also changing, becoming more sophisticated and offering further options to those seeking to become more actively engaged in an increasingly decentralised electricity network.

Type of battery

  • Most home energy storage batteries are lithium-ion. These are lighter, smaller and longer lasting than lead-acid batteries. They have a high energy density (kWh/kg), so can store more electricity for their size, and can discharge a larger amount of power at any one time. They are also more efficient than lead-acid batteries in terms of energy loss and need less care to  maintain  battery health.

Solar panels play a significant role in transforming how we generate and consume energy across various sectors, including water, gas, and electricity. Here’s how solar panels intersect with each of these utilities:

Solar panels are most associated with electricity generation. Photovoltaic (PV) cells within solar panels convert sunlight into electricity. Homes and businesses with rooftop solar installations can generate their own electricity, reducing reliance on the grid and often contributing excess power back to it through net metering. Large-scale solar farms also feed electricity directly into the grid, providing clean energy to utilities and communities

Water Heating:
Solar thermal systems, distinct from solar PV, use sunlight to heat water directly. Solar water heaters consist of collectors that absorb sunlight and transfer the heat to a fluid, which then heats water for domestic use or space heating. This technology is particularly efficient in sunny regions and is widely used in residential, commercial, and industrial settings. Solar water heating systems help reduce the energy demand for heating water through conventional methods.
Gas (Thermal Applications):
While solar energy is not directly harnessed for gas production, there are applications where solar thermal energy can indirectly contribute to gas-related processes. Concentrated solar power (CSP) systems use mirrors or lenses to focus sunlight, creating high temperatures that can be employed for various purposes, including thermal processes in industrial applications. Such applications can potentially reduce the need for conventional heating methods that use natural gas.

Energy Storage:
Solar panels, especially when combined with energy storage systems like batteries, contribute to the overall reliability of energy supply. Excess electricity generated during the day by solar panels can be stored for later use. This has implications for smoothing out the intermittency of solar power, ensuring a more consistent energy supply, and supporting grid stability.

Hybrid Systems:
Hybrid energy systems combine solar power with other energy sources, such as gas or other renewables, to create a more balanced and reliable energy supply. These systems often involve intelligent control mechanisms to optimize the use of each energy source based on availability, cost, and demand.
