Photovoltaic otherwise known as Solar Electricity is a process that converts light from the sun into electricity. At the heart of a solar PV are Photovoltaic cells; these cells are devices that are able to convert light into an electric current. The strength of a PV cell is measured in kilowatt peak (kWp) that is the amount of energy the cell generates in full light. These cells are combined into PV panels to protect the cells from moisture and mechanical damage. The actual Photovoltaic cells don’t need direct sunlight as they still produce energy on cloudy days; they are not activated by heat but light! This means you are generating electricity whenever there is light. Therefore the PV system will generate electricity all year round but of course produce more electricity when there is a greater amount of direct bright light or sunlight. The stronger the sunlight, the more electricity is produced. Where can I put Solar PV, How much space do I need? PV systems can be mounted in a range of locations, but the roof of a building usually provides the best and most practical site. For maximum efficiency the system should be south facing with a slope of around 30-40 degrees, but other orientations and pitches are often viable with relatively little drop in performance. Any shade such as trees or neighbouring buildings, can have an impact on the performance of a PV system. To work effectively, the whole PV array needs to be free from shade for the majority of the day. PV systems are modular, allowing a great degree of flexibility in design and specification. In practice the size of a system is often determined by the available space, but systems may be specified to meet a CO2 or energy generation target, or budgetary constraints. To give some idea, a 1kWp PV array would need at least 8m2 and, if optimally orientated and un-shaded, will generate approximately 833kWh (kilo-watt hours or units) of electricity each year. The CO2 emission saving for this system is approximately 0.43 tonnes per year. Will I need Planning Permission or Building Control? Fixing of solar panels to a roof or wall is likely to be considered ‘permitted development’ under planning law with no need to apply for planning permission. However, if you are in a conservation area, national park or world heritage site permission will have to be granted from the local authority. There are regulations for the installation of on-roof or wall solar installations, but the PAARL Energy engineer who carries out your site survey will ensure your system is specified within these. PAARL Energy is permitted to sign off all work under Part P of Building Control and issue the relevant certificate. In rare circumstances – if your building is listed, or if the structure of the roof needs to be changed – then Building Control will need to be consulted. The PAARL Energy engineer who carries out your site survey will be able to cover this in more detail on the odd occasion that it is necessary. Which Solar PV brands? PAARL Energy can provide a wide range of panels and other components. We are happy to provide an unbiased view of the options available and their suitability for a specific system. We can supply panels from all popular manufacturers including Schueco, Siliken, SCHOTT Solar, SANYO and Samsung, and inverters from SMA, Dielh or Tigo. What is the process for a new PV solar system? Stage 1 – Site Survey At a time arranged to suit you, a PAARL Energy engineer will come and conduct a site survey. They will assess key factors for the proposed installation including the roof structure, roof type, shading and orientation. The engineer will give honest advice on the different types of products highlighting advantages and disadvantages. Note – all our surveys are carried out by engineers not sales people to ensure you get accurate, unbiased information. Stage 2 - Quotation Following the survey a quotation will be sent detailing the best solution discussed in the site survey.  This will include the materials list, price, weight load calculations, the yearly energy that will be produced by the proposed installation and the Return On Investment (ROI) you may receive.   Stage 3 - Acceptance If you are happy with the quotation, sign it and return it to the office along with your deposit. Note: no deposit is required on works under £10,000.00. Your installation date will then be agreed. Stage 4 – Installation The day before your installation date any scaffolding needed will be erected by PAARL Energy. Then, on the day of installation, PAARL Energy engineers will arrive between 8.00am and 9.30am and run through the installation process ensuring everyone is in complete agreement before work starts. After the installation is complete an engineer will run through the system demonstrating equipment and isolation procedures, answering any technical or other related questions. You will receive a handover pack and PAARL will register your system with MCS. Payment is made (less your deposit) and PAARL Energy will issue your MCS certificate. Stage 5 – Follow up We will give you a call to check that everything has been completed to your satisfaction and that all paperwork is in place. Why choose a Heat Pump? A well designed and correctly installed heat pump can account for all your heating and hot water needs giving you 400% efficiency, compared to a conventional boiler system. There is no combustion with a heat pump, which means there are no harmful emissions, no fumes, no need for flues (duct, pipe, or chimney), no need to worry about carbon monoxide in the home and heat pumps also require very little maintenance. For smaller properties air source heat pumps do not require large space as they extract heat from the air rather than the ground and operate at temperatures of -20C. Ground source heat pumps require larger surface areas of ground space due to their extraction of heat from the ground. Why choose PAARL Energy for Heat Pumps and Underfloor Heating? PAARL Energy is an approved reseller and installer of Danfoss Heat Pumps UK, which are approved under the Microgeneration Certification Scheme (MCS). We offer heating system design with specialist software that can size a heat pump to suit your needs. The system provides you with financial calculations on energy consumed, carbon emissions reduced and of course ‘money’ saved!  We combine unrivalled knowledge and expertise with reliable products and the reassurance of prompt and efficient after sales service, which include tailor-made warranties. We offer Air and Ground source heat pumps commercial and domestic buildings of all sizes. What are the benefits of Solar Thermal? By installing a solar thermal system you can make an active contribution to reducing your carbon foot print – the average domestic system can reduce carbon emissions by around 325kg per year on gas or 635kg on electricity. Solar thermal can provide between 40% and 70% of your hot water throughout the year and give independence and security against rising fuel prices and tax increases. The Institute of Chartered Surveyors estimates that solar thermal can also increase the value of your property by up to 8.6% and you may find that grants are available to help with the initial installation cost. The UK Government is also considering offering some form of payment for the energy generated by solar thermal systems, but this is not yet finalised and is not guaranteed. If you are in a remote location, use oil or bottled gas for your hot water heating, or have a swimming pool then solar thermal can be particularly beneficial.
