Feasibility of a Photovoltaic System on a vertical extension.

1 Introduction

The vertical extension project consists of the design and construction of new residentials to be built on an existing building. The project provides a prime opportunity for architects and engineers to design in a sustainable manner by considering incorporating an alternative energy system into the design. Such a system would provide energy costs reductions and would also serve to make a positive, visible statement about the ethics of all organisations involved.

The technology to be investigated is photovoltaic cells, which convert the sun’s solar energy into electrical energy to supplement power obtained from the national grid. In this report, it has been proposed that the modules could be situated on the roof. This report intends to assess the feasibility of the proposal by considering the options available, associated costs, structural impact and associated benefits.

2 Case study

It is important that this assessment of photovoltaic systems is performed with specific relation to the Vertical extension design criteria. There are many options available for PV systems where the type of cell and the mounting structure vary greatly and the appropriate combination for this project must be chosen. The deciding factors will be the available budget, the energy output required and the location and design of the roof.

The extension consists of a kind of multi-storey building in Paris, rectangular in shape(30m*12m), and although at present the roof design has not been specified, it is likely that it will consist of a two-part slope with some roof lights.

Some pros and cons of PVs are listed below.

Advantages Disadvantages

• No moving parts • Ultra-low maintenance • Extremely long life

• Non-corrosive parts • Easy Installation • Modular design • Universal application • Simple controls

• High initial cost • Sensitive to shading • Variable generation

• Lowest output during winter • Low voltage output difficult to

transmit • Lack of affordable power

storage technologies that

could help offset the intermittent generation aspects of PV

They also have the advantages of a long life (over 50 years), remote application, free operation and the ability to be used as a building component, such as roof tiles. With technological developments their use in buildings is becoming increasingly attractive.

The two main impediments to the use of PV are the high cost and the relatively high environmental impact associated with their manufacture. Other sources suggest that it takes around 3 years of use for a PV panel to repay the embodied energy from

manufacture and transport.

The optimum angle of elevation of a PV cell is 20 degrees less than the latitude of the location. This suggests that the optimum angle of elevation of a PV panel located in Paris is approximately 35 degrees. This tilt has been change to 25 degrees for architectural and structural design reasons; a higher tilt would have created a large lost space under the roof. It has been observed however that the efficiency of all PV

cells varies by as little as 15% with lateral orientation.

In order to have a realistic study, two kinds of panels from SYSTAIC have been used. (cf product criteria)

E140

135 W silicone crystalline panels which allow really high quality integration

S230

225 W silicone crystalline panels which allow a classic integration

At this stage it is only possible to perform a very rough calculation since details of the internal services are not known; however, an implantation exercise has been carried out with 5 scenarios:

� Scenario 1: 30.9 kW Monocrystalline E140 system south orientated

� Scenario 2: 33.8 kW Monocrystalline E140 system :16.9kW East orientated / 16.9kW West orientated

� Scenario 3: 35.5 kW Monocrystalline S230 system south orientated � Scenario 4: 35.5kW Monocrystalline S230 system :17.78kW East orientated /

17.78kW West orientated � Scenario 5: 4.72 kW Monocrystalline S230 system south orientated

A detail of the products used and of the system specifications are as adjuncted documents at the end of this note.

3 Summary

The capital cost of any PV installation would naturally be high, due to the current

expense of the PV arrays. However, with the areas of roof available for potential use with building integrated PVs, a significant amount of useful electricity could be produced. PVs will also have a visual impact that will promote this king of project as a low energy and efficient building. The cost analysis should prove useful in determining whether a PV system is feasible.

However, this cost analysis give a realistic approximation of an important implantation improving the energetic balance and diminishing the carbon footprint of the overall building. There is much scope for obtaining further grants or scaling down the system to meet the available budget. More importantly, such a method of cost analysis does not fully evaluate the value of a sustainable system such as this. The system

offers educational value, image marketing value for all involved and very importantly is valuable move towards a sustainable way of building. A detailed analysis of the solar path is needed to identify any problems there might be with the roof being shaded by the surroundings or adjacent buildings however in principle there is no barrier to successfully implementing a PV system within the

current project proposal. It will be of importance to study the lifespan of the vertical extension, even if the Payback is around 15 years for this kind of solar installation, the Solar arrays are warranty for 25 years at 80% of their power and have a life expected of 50 years.

The vertical extension lifespan being itself dependent of the lifespan of the existing building, he main concern for such a system is then the lifespan of the combined building (existing + vertical extension).
