Frequently Asked Questions
Please explain the technology used by Mespil Solar Energy?
We install ground-mounted, solar photovoltaic (PV) panels primarly on fixed tilt systems. The cells in the panels are made of semiconductor materials. When sunlight hits the cells, it knocks the electrons loose from their atoms. As the electrons flow through the cell, they generate electricity. Using an electronic device called an inverter, the electricity generated is converted and fed into the public electricity grid.
Can the solar farm produce power when the sun is not shining?
Solar projects generate electricity during daylight hours when demand for electricity is at its highest. PV panels will generate electricity even when there is cloud cover but the more sunlight the more energy generated.
How does Mespil Solar Energy select sites on which to build solar farms?
We take great care over site selection. Ideally a site will be relatively flat, well screened (but not shaded) and cover an area of at least 25 hectares. We carry out a detailed feasibility study on prospective sites which involves assessing the environmental, visual and ecological impact of the site as well as the proximity to the grid, roads and dwellings.
Can you outline the process following site selection?
We take full responsibility for the design, build and maintenance of the solar farm. The process can be broken down into 10 simple steps:
- Initial consultation and preliminary site inspection
- Feasibility study of site (incorporating local environment and community impact assessment)
- Presentation of commercial proposal to the landowner
- Design of solar photovoltaic system
- Secure planning permission and grid application
- Installation
- Testing and commissioning
- Ongoing maintenance during lifetime of the contract
- Bi-annual inspections
- Decommissioning or Lease Removal
How long will it take to develop the site?
Though it varies from project to project, the average time from initial consultation to commissioning is 12-24 months.
What is the impact of the building phase on the surrounding area?
- A ground-based solar park has very little impact, either visual or environmental. In fact, solar energy is viewed as an inexhaustible fuel source that is pollution and noise free.
- The site is easily screened by hedges and trees. This planting creates excellent habitat for wildlife, improving biodiversity.
- From the perimeter, noise levels from the farm will be the same or below other background noise such as wind and traffic. The inverters and transformers make a low humming sound equivalent to less than 50 (dB) of noise (equivalent to the sound level inside a typical house).
- PV technology does not require water to operate. Water is required only for cleaning panels.
- PV installations require very little maintenance or intervention after their initial set up so apart from delivery of panels and other equipment, vehicle movements are minimal
What’s the environmental impact of a solar farm?
We install ground-mounted, solar photovoltaic (PV) panels primarly on fixed tilt systems. The cells in the panels are made of semiconductor materials.

What is the impact to the land?
The site will be levelled and there will be minimal digging for cable laying. There will be some gravelling to facilitate access to panels. Grass will continue to grow between panels so grazing small animals on the land can continue. Planting along the perimeter will ensure that the solar farm is screened and will create habitat for wildlife. At the end of the solar park’s life, the land can revert simply and quickly to agricultural
