Solarise Photovoltaic (PV) Solar Energy Systems

The way in which buildings create and consume energy can have a significant environmental impact

Solarise utilises solar power energy through PV panels, making it one of the most versatile renewable technologies you can choose. Suitable for use with all Garland roofing systems, Solarise is the perfect energy solution to reduce the operational carbon of your building.

Whether it is for generating electricity or for heating and hot water applications (solar thermal), there are significant environmental benefits to be gained by incorporating a PV panel system into your building’s roof design.

How does the Solarise system work?

  1. The Solarise system can be installed on top of any Garland waterproofing system. The photovoltaic (PV) panels directly convert sunlight into energy, through a series of solar cells. PV systems only require daylight rather than direct sunlight to generate electricity, giving you a guaranteed energy source even on a cloudy day.

  2. When sunlight hits the Solarise panels, photons are converted into electrons. As these electrons pass through the cells of the panel they’re converted into electricity. The higher the intensity of the sun, the greater the number of photons, the higher the flow of electricity.

  3. PV cells produce electricity in the form of a direct current (DC), which is in contrast to the power used by conventional mains electrical equipment which is Alternating Current (AC). An inverter is needed to convert DC electricity to AC, for the building’s immediate use.

  4. The PV panels are always on and continuously generate electricity during daylight hours. When the electricity you generate is more than you can use then batteries can be installed to prevent exporting unused power. If the batteries are full, then any surplus power is usually sold to your energy provider.

Design Considerations

In the early concept stages, the project viability, carbon reduction and yield capabilities of your roof will be carefully assessed by your dedicated Technical Manager. We remove the unknowns ensuring optimum performance and return on investment are achieved.

Building energy usage

Understanding the building’s day to day operations will have a significant impact on the PV panel design, whether it is a school that is open 5 days a week to a factory that is open and running 24 hours a day, 7 days a week.

Pitch and orientation

Solarise can be installed on a building of any orientation. Consideration of the roof pitch will ensure the PV panel design is not affected by high shade areas, or alternatively if a wall-mounted system may be more suitable.

Roof structure

The volume of PV panels required to meet your desired energy requirements can considerably increase the load on the existing roof structure. Early consideration, during the design stage, will assess the structural integrity of the roof.

Existing plant & access points

Your Technical expert can advise on a bespoke PV panel design to maximise carbon reduction and energy yield, whilst allowing for your existing roof access, plant and service requirements.

Green Roofs

A perfect way to bring underutilised roof spaces to life. Combining green roof and PV panels provides an ultra-sustainable roof, that has been carefully engineered to offset the building’s operational carbon footprint.

Planning permission

Typically the installation of a PV system doesn’t require planning permission. Your Technical Manager will consult with your local authority to ensure the installation is compliant and meets all levels of Building Regulations.

Installing a Solarise system will provide an excellent return on capital investment, with typical payback between 4-6 years.

The Solarise system will pay for itself in a short space of time, effectively producing free energy for a building and a significant cost saving for the building owner.

As electrical tariffs rise, these returns will become quicker, and businesses will likely see themselves paying off the initial cost of installing PV panels around year 4. Meaning from year 5, they will save on their annual running costs.

Our Technical Managers will work with you to conduct a detailed survey of your building, creating a tailored report that accurately calculates the energy-saving and financial benefits of your Solarise installation.

PV System Components

Photovoltaic (PV) Panels

The PV panels convert light into direct current (DC) electricity. Assembled with multi-busbar PERC cells, the half-cell configuration of the PV panel modules offers the advantages of higher output power, reduced shading effect on the energy generation and advanced tolerance to mechanical loading.


Connected to the PV panels via DC cables, inverters convert DC into alternating current (AC) electricity for use in buildings.

Frames & Fixings

To secure the PV panels to a roof, wall or surface a variety of different frames and fixings are available to choose from.

Solarise Frequently Asked Questions

The Solarise PV solar system can be installed to a wide range of roofing systems.

When considering solar energy systems there are several factors that need to be considered in order to identify the energy requirements of your building.

If you still have any questions please contact your Garland Technical Manager.

What type of maintenance is required?

Solar panels are generally self-cleaning, especially if positioned at an angle of over 15 degrees.
We advise that Solarise systems be visually inspected once a year and cleaned if necessary.

Do you need a south-facing roof?

Solarise panels have a range of frames, mounts and fixings, which means that whilst the south-facing roof is preferred, north-facing roofs can still benefit. The Solarise system can be installed on any roof orientation and still achieve electricity generation targets.

How long does it take to install a Solarise system?

The Solarise system is simple to install and will typically be completed in 1-2 days, depending on the size of the installation.

How long does it take to see a return on investment?

Renewable energy generation provides an excellent return on capital investment, where on average, you can expect to see a return on your investment in as little as 4 years and typically within 6 years of a Solarise installation.

How much energy will Solarise generate?

This will depend on several factors, such as the building’s geographical location, orientation and pitch. Your dedicated Technical Manager will carry out detailed surveys and reports to calculate the expected energy savings and financial benefits of your Solarise installation.

How long will the Solarise system last?

Solarise comes with an industry-leading, 10-year Single-Point Guarantee. Built to last, the Solarise panels will generate at least 80% of the initial output in the 25th year.

Where can Solarise be installed?

The bespoke frame and mounting options ensure the Solarise system can be installed on any Garland UK waterproofing system. This includes bituminous membranes, metal profiles, cold-applied liquid coatings, or green roof systems.
