Solar PV 

How does it work?

As a Renewable Energy source, Solar Photovoltaic (Solar PV) panels generate electricity from daylight (Solar Irradiation).

The higher the intensity of solar irradiation the more electricity they generate so, they work on both sunny and cloudy days.

Solar electricity can be used in our Commercial and Residential buildings to reduce the amount of grid-electricity we all need to use and pay for every year.

By using less grid electricity, we also reduce our harmful carbon emissions and help the environment.

It’s no wonder then, that 90% of all renewable energy systems installed so far in the UK are Solar PV.

Flexible solutions

Solar PV arrays can be installed on virtually any roof type; they can even be ground or wall-mounted and building integrated. Panels facing due south are ideal however east - west systems are also highly productive. 

Flat roofs are often particularly good sites as it is easier to optimise the panels so they capture the most solar irradiation.

Hassle Free Installation

In addition to new-build, Solar PV is an ideal retro-fit property improvement. Apart from the initial survey and the final hook-up to your mains supply, virtually all the work takes place outside.

Most installations are carried out within 1-5 working days so disruption is minimal and for the occupants of the property, life carries on as normal.

The Aesthetic Choice

Panel design has evolved. We now specify and install all black panels or in-roof panels which barely show at all. There are even solar tiles available with different options to suit virtually all types of roof surface.

We will advise you on all the options available that suit your particular building.

Is it reliable?

As there are no moving parts in a Solar PV system they require only periodic maintenance and are covered by a warranty and guarantee that can be extended for a term of up to 20 years.

For larger commercial scale systems we recommend and provide an Annual Maintenance Contract. Please see our Solar PV Servicing & Maintenance section for more details.

Solar PV has come of age

Solar PV is the renewable technology whose time has come. Driven by increased competition and market demand, Solar PV panel production volumes have increased worldwide and so unit costs have come down. Simply put, they are as low as they are likely to get and this means that installing a Solar PV system has never been more affordable or offered better value for money.

The Feed in Tariff

Once a system has been installed, the building becomes a micro-generator and an application to join the UK Governments ‘Feed-in-Tariff’ (FIT) scheme can be made.

It is a straightforward process and the benefits that accrue to the owner of the system for the micro-generation of electricity are as follows:

Generation payments

The amount of electricity (kWh) produced by the Solar PV system is measured via a meter we install (Total Generation Meter) and under The Energy Act 2008, through your electricity provider you are paid for every kWh the system produces.

It does not matter who uses the electricity, the fact that you generate it qualifies you to receive the FIT payments, which are index-linked, guaranteed for 20 years and usually paid quarterly according to the meter reading you provide.

The amount you are paid for each kWh of electricity varies according to the kWp size of the system with three broad categories:

1 > 10 kWp
10 > 50kWp
50 > 250 kWp

Any electricity generated that is not used in the building automatically flows back to the grid and will be used by someone else.

Export payments

With the exception of larger systems ie greater than 30kWp (100 panels), the amount exported is not measured. Instead it is ‘deemed’ and everyone is assessed as having exported 50% of what they have generated.

You will receive a smaller payment for each kWh of electricity you are deemed to have exported. Export payments are also index-linked and guaranteed for 20 years.

For Commercial scale systems greater than 30 kWp the amount exported is usually measured via the installation of an Export meter and payments made on that basis.

It is the total of these two payments that represents the Annual Benefit the system owner receives under the FIT Scheme.

Annual Saving off your electricity bill 

With a Solar PV system there is a third annual benefit that accrues to the system owner.

Your building will always use any electricity produced by the Solar PV system before any additional power, required to meet the buildings demand, is brought in from the grid.

In this way, because you are using your own electricity you will import less from the grid and so your annual electricity bill will be lower. In fact, the more solar electricity you use, the greater the saving you will make off your bill and the faster the PV system will pay back.

As commercial properties tend to use the majority of their electricity in the daytime they generally benefit from a greater saving off their annual electricity bill and higher return on investment percentage. If high demand appliances and/or machinery are involved, bills will be even lower.

Solar PV really is the property-improvement investment that pays for itself over and over again.

Energy Efficiency Requirements

To ensure that your building will qualify to receive the highest starting Feed in Tariff payment per kWh generated, you will have to show that your building achieves an EPC (Energy Performance Certificate) rating of D or better.

If you do not have an EPC for your building we can provide this for you subject to a fee depend on the size and complexity of the building.

The Green Option

Solar PV reduces your reliance on non-renewable energy sources like gas, coal and oil and secures your future against rising energy prices. At the same time, you will have the satisfaction of knowing that by using less grid electricity, you are doing your bit for the environment by cutting your emissions of harmful CO2 and thereby reducing your carbon footprint.

This in itself can be leveraged in your favour as far as occupant/employee attitudes are concerned not to mention the CSR and PR opportunities for organisations.

Planning Permission

Even in conservation areas most installations do not require planning permission, indeed local authorities are only too keen to see the community install renewable energy systems.

However, there are cases where property owners will need to seek planning approval for their project. In these cases, Treadlighter will be able to guide you through the process by assisting with the preparation and submission of your application.

If you think a Solar PV installation at your property might be require planning permission, we have the knowledge and experience to help you.

Adding Value to your property

With an installed base of 925,000+ Solar PV systems in the UK and grid electricity prices going only one way, experts now agree that minimising grid energy usage to produce lower running costs, ranks highly in determining property decisions. Who wouldn’t prefer to occupy an energy efficient property?
