2. Solar Energy Why are we interested in using solar energy?

3. Solar Energy Sunlight provides the energy source that powers the Earth’s climate and ecosystem. Harnessing this energy for hot water and electrical powercould provide a renewable, low carbon energy source, and presents anattractive way of mitigating climate change.

4. Solar Energy How can we use solar energy?

5. Solar Energy We can use solar energy to produce Energyas below Solar Thermal Energy - to provide heat Photovoltaic Energy - to generate electricity

6. Solar Thermal Energy Solar thermal electric energy generation concentrates the light from the sun to create heat, and that heat is used to run a heat engine, which turns a generator to make electricity. The working fluid that is heated by the concentrated sunlight can be a liquid or a gas. Different working fluids include water, oil, salts, air, nitrogen, helium, etc. Different engine types include steam engines, gas turbines, Stirling engines, etc. All of these engines can be quite efficient, often between 30% and 40%, and are capable of producing 10's to 100's of megawatts of power.

7. Photovoltaics (PV)Technology Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material.

8. Photovoltaics (PV)Technology In the world of photovoltaic (PV) solar power, there are several types of semiconductor technologies currently inuse for PV solar panels. Two, however, have become the most widely adopted: Crystalline Silicon Thin Film

9. Crystalline silicon Crystalline silicon panels are constructed by first putting asingle slice of silicon through a series of processing steps,creating one solar cell. These cells are then assembled togetherin multiples to make a solar panel. Crystalline silicon, also calledwafer silicon, is the oldest and the most widely used material incommercial solar panels. There are two main types of crystalline silicon panels: Monocrystalline Silicon Multicrystalline Silicon

10. Thin film Thin film solar panels are made by placing thin layers ofsemiconductor material onto various surfaces, usually on glass.The term thin film refers to the amount of semiconductormaterial used. It is applied in a thin film to a surface structure,such as a sheet of glass. Contrary to popular belief, most thinfilm panels are not flexible. Overall, thin film solar panelsoffer the lowest manufacturing costs, and are becoming moreprevalent in the industry. There are three main types of thin film used: Cadmium Telluride (CdTe) Amorphous Silicon Copper, Indium, Gallium,Selenide (CIGS)

11. Planning a PV project Building-up a large-scale photovoltaic installation requires several steps and preliminarysurveys in order to confirm the reliability of the project. Each phase is essential and it takesaround 6 months to achieve the project.

12. Project Overview PHASES PHASE 1: PRE-FEASIBILITY STUDY PHASE 2: PV SYSTEM DESIGN PHASE 3: BUSINESS PLAN PHASE 4: PERMISSION PLANNING PHASE 5: SELECTION OF SYSTEM / SUPPLIER PHASE 6: SYSTEM INSTALLATION PHASE 7: MANAGEMENT OF THE INSTALLATION PHASE 8: END-LIFE OF THE INSTALLATION

13. PHASE 1: PRE-FEASIBILITY STUDY That’s the first step of the project. When the decision is made to invest in a photovoltaicsystem, it is required to collect all the useful information in order to identify the interest andthe feasibility of the project. A- Site selection One of the great advantages of solar photovoltaic is the simplicity of its installation, and acertified installer will do most of the work for you. However, essential criteria are required: -Orientation: Ideally, the surface should be south facing at a30-40° angle. Most farm and industrial building roofs are notat this angle, but the mounting system can be adjusted toprovide the output needed.

14. PHASE 1: PRE-FEASIBILITY STUDY -Location: Avoid shade, although solar systems do not needdirect sunlight to generate electricity, they will work muchbetter the more they receive. The South of England is bestsuited because it is generally sunnier, but most parts ofEngland have sufficient daylight to make it viable. -Presenceof grid utility to feed the electricity networkauthority. The production of electricity will be sold to thenational grid. Suitable electrical installation must be closethe installation and meet local utility interconnectionrequirements. - The photovoltaic system size depends on the project budget, the size of the roof (forroof mounted systems) or the land (for ground mounted systems) and on the type ofsolar modules used.

15. PHASE 1: PRE-FEASIBILITY STUDY B- Collect of information and technical surveys Before moving forward in the project, two things to do: - Collect the useful information: geographical position, building or land dimensions, sunirradiation, cadastre, maps, pictures, etc. - Topographical, building structure and environmental impact surveys.

16. PHASE 2: PV SYSTEM DESIGN The photovoltaic installation design is done by an renewable energy consultancy specialized in photovoltaic system design and able to provide the most appropriate system based on the following criteria: -Sunlight and weather resistant materials for all outdoor equipment.-Array location to minimize shading from foliage, vent pipes, and adjacent structures.-System design in compliance with all applicable building and electrical codes.-System design with a minimum of electrical losses due to wiring, fuses, switches, and inverters.-System design meets local utility interconnection requirements. -Roof area or other installation site is capable of handling the desired system size.

17. PHASE 2: PV SYSTEM DESIGN A- Estimating system output PV systems produce power in proportion to the intensity of sunlight striking the solar array surface. The intensity of light on a surface varies throughout a day, as well as day to day, so the actual output of a solar power system can vary substantial. There are other factors that affect the output of a solar power system. These factors need to be understood so that the Municipality has realistic expectations of overall system output and economic benefits under variable weather conditions over time. -Calculate your roof size to determine the maximum size of your PV system -Analyze the orientation of your roof, incline and shading to determine how much sunlight your system is able to capture and if your system operates near its rated efficiency -Solar radiation of your geographical region

18. PHASE 2: PV SYSTEM DESIGN B- Select the mounting system A wide range covering all possible scenarios of photovoltaic installation, from the building integration to the PV plant on ground. Ground mounting systemOn roof mounting systemBIPV

19. PHASE 2: PV SYSTEM DESIGN - Roof mount is often the most convenient and appropriate place to put the PV array is on the roof of the building. The PV array may be mounted above and parallel to the roof surface with a standoff of several inches for cooling purposes. Sometimes, such as with flat roofs, a separate structure with a more optimal tilt angle is mounted on the roof. - Ground mounted solution that can be used in almost all kinds of situations, from residential to large commercial, right through to utility scale. - Building-Integrated PV Array (BIPV) is another type of system allows easy integration of framed photovoltaic modules into the roofs of buildings, old and new, whatever the existing structure. This smart and innovative system has been developed to be a versatile integrated solution.

20. PHASE 3: BUSINESS PLAN A- Feed-in-tariff At this step of the project, it is valued the profitability according to the electricity production forecast on 25 years running of the PV installation considering the total investment. Feed In Tariff rewards solar PV up to 5MW capacity. The FIT is designed to enable a Return on Investment (ROI) of 5-10 per cent each year for well-sited PV installations.

21. PHASE 3: BUSINESS PLAN B- What to consider for solar PV finance: - Generation Tariff: the price your energy supplier gives you for every unit of electricity produced, irrespective of whether you use it or export it. - Export Tariff: a minimum of 3p/kWh for all electricity exported to the Grid, this can be more depending on supplier and if you enter into a power purchase agreement. As an interim measure, payment of export tariffs to generators of 30kW or less will be made on the basis of deemed or estimated exports. The amount of electricity deemed to be exported for solar PV generators will be 50 per cent – as a proportion of the metered generation output. (This will not apply if export meters are fitted). - Lower bills: account for the reduction in your energy bills if you use your own power.

22. PHASE 3: BUSINESS PLAN B- What to consider for solar PV finance: - Index linked: tariffs are linked to the Retail Price Index for electricity meaning your tariff will keep pace with inflation. - Tariff digression: the earlier you invest in renewable technologies, the greater the financial benefits. After 2012 the tariffs start to reduce, owing to the projected expansion of the PV market (up to 250MW of new solar capacity by 2011, compared to 22MW in 2009) which is expected to lead to lower technology costs. - Capital grants: the scheme generally prohibits recipients of grants from receiving FITs as this would mean they get a double benefit.

23. PHASE 4: PERMISSION PLANNING A- Documentation -Permission to install is dependent on the view of the local planning authority that will make a decision based on the views of the local planning committee. -Environmental Impact Assessment: an EIA would be required for an installation. -Planning permission: A Planning Application will need to be submitted with necessary supporting documents. -Planning decision: local Authority validates application and requests any missing documents Recommendation to Committee if not delegated and/or recommendation

24. PHASE 4: PERMISSION PLANNING B- Support scheme Check if installations above X kWp , must be registered on Support structures process before an application is made to an Electricity Supplier. All suppliers with more than 50k domestic customers must offer FITs, smaller suppliers can volunteer to do so. A list of Licensees can be found on the Ofgem website. A generator can assign their right to FITs payments to a third party (nominated recipient) by way of bilateral agreement. C- Grid connection permit The connection of the solar PV system requires any grid connection point will need to becompleted based on regulations

25. PHASE 5: SELECTION OF SYSTEM / SUPPLIER A- Components of a PV system The main components of a PV system include: - Solar panels, either mounted on the roof or the ground, or replacing the roof material. - Inverters, which turns the electricity from the panels into a form you can use for your home or business. Convert DC power into AC power. - System Monitoring provides feedback to the customer about the power and energy metering. Without proper metering the customer will never know whether the system is operating properly or not. - Mounting systems, on-roof, grounded or BIPV. - Cable and connectors, different length and section.

26. PHASE 5: SELECTION OF SYSTEM / SUPPLIER B- Selection criteria When choosing a supplier and specifying a PV system, the following criteria help the decision-making process: - Company profile, reputation and references in similar projects - Technical advantages and innovative products - Quality and certification (such as MCS) - Competitiveness - Warranty and insurance

27. PHASE 6: SYSTEM INSTALLATION A - Set up the photovoltaic generator The D-Day has started. After months and months, the installation begins and can go on for days depending of the number of modules to install. B - Wiring and commissioning That’s the final steps to the commissioning. All the installation is wired. After a final inspection, the installation will be ready to produce electricity. C - Grid connection There will be a detailed procedure for this set out or referred to in the "construction and adoption" agreement which is not standard. There is no "legally set" process for testing and acceptance followed by adoption.

28. PHASE 7: MANAGEMENT OF THE INSTALLATION A - Monitoring system With the decision for a PV system, you also decide for a long-term source of income. It means that the system must function smoothly at all times. The best way to manage your PV installation and your production of electricity is to use monitoring devices: Communication hub. It continuously collects all the data from the inverters on the system side, thereby keeping you informed of the System’s status at any given time: system monitoring, remote diagnosis, data storage and visualization of the production of electricity.

29. PHASE 7: MANAGEMENT OF THE INSTALLATION A - Monitoring system Web portal for professional management. Whether for a small home system or a large solar park, central administration and monitoring of several PV plants saves time and money. Plant operators, installers and inverter manufacturer service technicians have access to key data at any time, from any location. The yields of all inverters in a plant are compared fully automatically, permitting detection of even the smallest deviations. Large-scale display. A large-format display visualises yield, performance and CO2 reduction of PV systems in large, luminous figures. it derives the display data from the communication hub via the Ethernet interface.

30. PHASE 7: MANAGEMENT OF THE INSTALLATION B - Maintenance Even if maintenance is minimal, there are no moving parts in the installation, so it is almost maintenance free. However, it is required to regularly inspect the installation: - Keep modules clean: If the PV installation is located in a dusty place and it doesn’t rain frequently, it is recommended to clean the modules (e.g. birds dejection). - Connectors: check if all the connectors are properly plugged and if no scratch or damage appear on cables. - Protection devices: check if all the protection devices are in operation. - Mounting system: check if no damage on the installation racks. - Electrical measurement on specific parts (inverters).

31. PHASE 8: END-LIFE OF THE INSTALLATION A - More than 25 years of production Depending on the feed-in-tariff scheme and the right to run the installation, the PV system can still run after 25 years. Indeed, the end of the FIT contract between the installation’s owner and the grid authority, doesn't mean the modules will stop produce electricity. The production of electricity will be use for your own consumption and will allow you to reduce your electricity bills. B - Decommissioning In some cases, land or roof are a concession for 25 years, and it will be required to dismount the full PV system. In that case, at the construction of the system, special material are used in order to recycle them after the life-time (e.g. use of ground screws instead of concrete foundation to avoid ground contamination).

32. PHASE 8: END-LIFE OF THE INSTALLATION C - Recycling The PV industry is working to create truly sustainable energy solutions that take into consideration the environmental impacts of all stages of the product life cycle, from raw material sourcing through end-of-life collection and recycling. Although the PV industry is young, leading manufacturers embrace the concept of producer responsibility and have come together to put in place a voluntary, industry-wide take-back and recycling programme. By addressing future recycling needs now, it can be offered a truly sustainable energy solution today to help prevent climate change tomorrow.
