Have peace of mind that the Stroma Network combines approved servicesand warranties, all certified members on the scheme ensure you receive:

n Qualified survey of your property to include clear quotations including yield and payback analysis, that you can measure your actual equipment performance against

n Government backed Microgeneration Certification Scheme (MCS) approved installers and products such as photovoltaic (PV) solar panels

n Access to Feed-in-Tariffs (FITs) only available in conjunction with MCS certification

n Accurately priced and fully assured service from start to finish, with an insurance backed warranty

Stroma’s experience and knowledge of energy performance in buildings sets us at the forefront of the sustainability and renewables markets.

You can be assured that we have worked with singledwellings to large developments and can assist in thetransition to a more sustainable built environment.

To qualify for the FIT scheme, renewable technologies such as solar PVmust be installed by an MCS (Microgeneration Certification Scheme)certified installer.

The Stroma Network connects a solar PV surveying, design and installation service nationwide, workingwith the Network means that you can be reassured that all surveys and installations conducted aremaintained by a Governmental approved certification system; all personnel involved at every stage arecertified and competent to carry out this activity.

The Network operates exclusively with MCS certified installers, ensuring that the highest level of competence and consumer satisfaction is maintained at all times. The Network provides technical support to all customers, surveyors and installers to make sure that every installation project has the appropriate levels of insurance and warranty cover in place.

Additionally, post installation performance monitoring is also provided at no extra cost. We do this to ensure the actual performance measured is in line with the design and warranty performance of equipment used.

From the 1st April 2010, Feed-in-Tariffs (FITs) became available adding benefit to the homeowner for installing renewable energy sources, whereby energy companies are obliged to pay householders a regular tariff for their production of renewable electricity such as electricity produced from a photovoltaic (PV) array.

Building Sustainability & Compliance

Solar Photovoltaic (PV)Producing FREE electricity direct from the sun

Solar PV systems utilise the sun’s free potential energy and use photovoltaic (PV) cell technology to turn the sunlight into useableelectricity, which in-turn can be used in a domestic capacity to runlighting systems and regular household appliances.

One of the main benefits to the UK renewable market is that you donot need direct sunlight to generate energy; the PV system has thecapacity to produce a certain amount of electricity even in overcastconditions.

Photovoltaic panels (PV Cells) can be attached to your walls or roofdepending on the optimum angle required for achieving the greatestenergy return.

The cells are made up of double or single layers of semiconductingmaterial which create electric fields when sunlight is applied, thegreater the amount of sunlight hitting the material the more electricity (measured in kWp) will be produced, therefore increasedfinancial savings.

Key Benefits

n Generate an income from Feed-in-Tariffs (FIT)Every kilowatt of electricity you produce will be rewarded regardless of whether you use it yourself, or sell it back to the grid.

n Reduce your electricity billThe sun’s energy is a free and renewable source, meaning that when you have covered the installation costs of the technology; your electricity bills will reduce.

n Reduction in your carbon footprintSolar energy systems do not discharge any carbon dioxide (CO2) into the atmosphere. It is estimated that a solar PV system installed on a typical residential property could save around 1tonne of CO2 per annum. (Source: Energy Saving Trust).

Monitoring Service

Post installation monitoring is included within the standard Stroma Solar PV package for a twelve-month period.

Stroma Network shall install the latest smart meter solution with an inbuilt SMS functionality; this will monitor the yield of your PV systemand provide you with a monthly summary of performance against thepredicted design and warranty level.

All data recorded by Stroma Solar is securely stored within the data centre. If required this monitoring service contract may be extended beyond twelve-months at a modest cost.

For further details of the benefit of having data analysis please refer tothe two case studies found on page 7.

Warranties

Ensuring quality assurance and consumer protection is the essence of the Certificationscheme operation. The Network will bring together a number of insurance and warrantiesin order to provide the owner with peace ofmind in their new PV solar installation.

Competent Person Scheme (CPS)

All installations will be undertaken by appropriate Competent Persons listed within theGovernment approved CPS. Each installation willbe undertaken with insurance backed warrantiesfor a minimum period of six-years.

Microgeneration CertificationScheme (MCS)

All products installed will include a 25 year output performance warranty for the PV panels. Furthermore, installers will be MCS certified in addition to CPS certified and shall provide Professional Indemnity for the design of the PV solution, as well as Public Liability for the physicalworks undertaken on the property.

Feed-in-tariffs (FITs)

The value of the FIT is index linked to the RetailPrice Index (RPI) for 25 years from the date of notification, defined by the MCS installer and isregulated by Ofgem.

PC Tablet with Bluetooth Connectivity

Building on the strength of the inbuilt Bluetooth Connectivity containedwithin the Sunny Boy HF inverter, Stroma Solar shall provide a PC Tabletto all occupiers for accessing key daily profile data, current output andtotal energy yields.

Data can be stored on the device indefinitely or on other peripheral backup device or PC. The live data canthen be analysed against the predicted design output and thewarranty performance levels,therefore providing reassuranceof the overall system performance for the life of the system.

The 7" touch screen PC Tablet may also be used for all other usual PC applications such as web browsing, multimedia applications and gaming.
