Case Studies

Domestic Solar PV Panels for Homes have become an                                              increasingly attractive option for homeowners.

Here are a few case studies that showcase the use of Solar PV Panels for heating:

The effectiveness of solar PV panels for heating depends on factors such as the location, climate, building insulation, and energy demand. In many cases, combining solar PV panels with energy-efficient building practices and storage solutions can maximize the benefits of using solar energy for heating. Additionally, advancements in energy storage technology, smart energy management systems, and heat pump efficiency can further enhance the viability of solar PV-based heating solutions.

  1. Residential Solar Heating System: In a residential setting, a family in Northern Europe installed a solar PV array on their roof and used the generated electricity to power an electric heat pump. The heat pump efficiently converted the electricity into heat, providing space heating during colder months and reducing their reliance on traditional fossil fuels. This case demonstrated how solar PV panels can contribute to space heating while also benefiting from net metering programs to sell excess electricity back to the grid.
  2. Off-Grid Cabin Heating: In a remote location where grid electricity was not available, a cabin owner installed a solar PV system along with a battery storage system. The generated electricity was used to power an electric heater, which provided comfortable indoor temperatures during cold seasons. This case illustrates the feasibility of using solar PV panels for off-grid heating applications.
  3. Greenhouse Heating: A commercial greenhouse operation implemented a solar PV system on their greenhouse structure. The electricity generated was used to power electric heaters and fans within the greenhouse. This approach helped maintain optimal growing conditions for plants and extended the growing season by providing consistent heating, even in colder months.
  4. Solar-Integrated Heat Pump: In a university research project, a solar-integrated heat pump system was developed. Solar PV panels were combined with a heat pump unit that could use both electricity from the grid and electricity generated by the solar panels. This hybrid system provided efficient heating and cooling for a building, with the solar component offsetting a significant portion of the electricity consumption.
  5. Net-Zero Energy Home: In a net-zero energy home design, solar PV panels were used not only to generate electricity for household needs but also to power a ground-source heat pump for space heating. The combination of energy-efficient building design, solar PV panels, and a heat pump allowed the homeowners to achieve a net-zero energy balance over the course of a year.

Ground Mount System - Solar PV Panels 


In a solar panel system, the ground typically consists of a grounding electrode, such as a ground rod or a grounding plate, that is connected to the electrical system's grounding conductor. The grounding conductor is a copper wire that runs from the solar panels to the ground electrode.

The purpose of grounding in a solar panel system is to provide a path for electrical current to flow into the ground in the event of a fault or surge, effectively redirecting the dangerous current away from the system and preventing damage or harm. It helps to stabilize the system's electrical potential and reduces the risk of electric shock or fire.

In this project we install Heat Pump.

Proper grounding is essential for safety and compliance with electrical codes and regulations. It is typically installed by licensed electricians or solar panel installers who are knowledgeable about local electrical codes and requirements.

It's important to note that while grounding is a crucial safety measure, it does not directly affect the performance or efficiency of the solar panels. The primary function of grounding is to ensure safety and protect against electrical hazards.

Roof Mount System - Solar PV Panels 

Kilmeadean, Co.Waterford

A roof-mounted solar photovoltaic (PV) system is a type of solar energy system where solar panels are installed on the roof of a building. These panels capture sunlight and convert it into electricity using photovoltaic cells, which can then be used to power the building's electrical systems or be fed back into the grid.

Roofs often provide an unobstructed and sun-facing surface, allowing solar panels to receive maximum sunlight throughout the day.

This exposure maximizes the solar panels' electricity generation potential.Solar panels on the roof are a popular choice for residential and commercial solar installations. Mounting solar panels on the roof offers several advantages, including optimal sun exposure, space efficiency, and ease of installation.

Solar panels can be installed on flat roofs, although the installation process and considerations may differ slightly compared to pitched roofs.

Flat roofs typically require solar panels to be tilted at an angle to optimize sun exposure and maximize energy production. The tilt angle is determined based on the latitude of your location and the desired energy output. South-facing orientation is generally recommended in the northern hemisphere to capture the most sunlight.

100kW of Roof Top Solar PV

This type of project involves integrating a solar photovoltaic system onto the roof of a horticultural facility, such as a greenhouse or nursery. The purpose of this installation could be to generate renewable energy to power the operations of the horticultural facility or to offset energy costs. Here's some information on what such a project might entail:

  1. Site Assessment: Evaluate the rooftop of the horticultural facility to determine its suitability for solar panel installation. Consider factors such as roof orientation, available space, shading, and structural integrity.
  2. Energy Needs: Assess the energy consumption of the horticultural operations to determine the size of the solar PV system needed. A 100 kW system implies that the installation has the potential to generate 100 kilowatts of electricity under optimal conditions.
  3. System Design: Collaborate with solar experts to design a system that maximizes energy production. This includes selecting the right solar panels, inverters, and mounting systems for the specific conditions of the rooftop.
  4. Permitting and Approvals: Obtain the necessary permits and approvals from local authorities. Depending on your location, you might need building permits, electrical permits, and compliance with relevant regulations.
  5. Installation: Work with experienced solar installers to install the solar panels, inverters, and other components on the rooftop. Proper installation is crucial for the system's performance and longevity.
  6. Electrical Integration: Connect the solar panels to the inverters, which convert the generated DC electricity into usable AC electricity. Ensure that the system is properly wired and integrated into the facility's electrical systems.
  7. Grid Connection: Coordinate with the local utility company to establish a grid connection. This might involve installing a bi-directional meter to measure both the energy consumed from the grid and the excess energy fed back into the grid.
  8. Monitoring and Maintenance: Implement a monitoring system to track the system's performance, energy production, and potential issues. Regular maintenance, such as cleaning the panels, checking connections, and inspecting for damage, will ensure optimal efficiency.
  9. Financial Benefits: Calculate the expected energy savings and potential revenue from any excess energy fed back into the grid. Consider factors like payback period, return on investment (ROI), and any applicable incentives or tax benefits.
