Solar Energy /Electrical Energy Generating systems
A solar panel, or photo-voltaic (PV) module, is an assembly of photo-voltaic cells mounted in a framework for installation. Solar panels use sunlight as a source of energy to generate direct current electricity. A collection of PV modules is called a PV panel, and a system of PV panels is called an array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.
A photovoltaic system typically includes an array of photovoltaic modules, an inverter, interconnection wiring, circuit breakers, fuses, and disconnect switches. Other secondary equipment but not necessarily required could be, a battery pack for energy storage, charge controller, voltage meters, and optionally a solar tracking mechanism. Equipment is generally ‘carefully selected’ to optimize output, the conversion from direct current to alternating current , energy storage, and reduce power loss during power transmission.
According to literature, the aspect of a property to which a solar generating system is to be affixed, logically affects the output of the system given that the sun changes position over the course of a day relative to the property.
Irrespective of the location of a property, the sun will always rise in the east and set in the west. The United Kingdom (UK) being in the northern hemisphere establishes that the sun is above the equator and therefore south facing solar panels will be optimally aligned in terms generated energy output.
Logically, many properties do not have an appropriate south-facing roof, hence given the trajectory of the sun and the rotation of the earth, in order of optimal location the next best would be west-facing, and then east-facing. North-facing panels are the least effective and are impractical in the UK.
Further, the pitch of a roof on which an array of solar panels is to be affixed, has a bearing on the output of the solar generating system According to literature , ideally a fixed, roof-mounted solar energy system should be at an angle that is equal to the latitude of the location where installed. Pitch angles between 30 and 45 degrees are optimal.
About Dr Robert Brown:
Eur Ing Dr Robert Brown (Robert) is the Executive Director of Fraser George and Associates Limited and is a Consultant and Forensic Engineer in the fields Electrical Electronic and Control Engineering.
Robert is an accomplished professional Electrical Expert Witness having prepared and presented many court compliant reports and presented oral evidence within the High Court, Crown Courts and County Courts.
Robert is a registered Chartered Electrical Engineer, specialising in the fields are control engineering, parameter data capture and accurate data ‘representation’. Robert graduated from Sheffield Hallam University with a first class honours degree in Electronic Systems and Control Engineering and followed this by completing doctorate research in Electrical Engineering, again at Sheffield Hallam University where Robert undertook research studies in the field of Disintegration and Arcing in Electrical Fuses. Robert is now considered to be a leading world expert in the field of electrical circuit protection systems, the phenomena of electrical fuse operation and the attributes of clearing ‘fault’ electrical current circumstances. Robert has published my pure and applied research studies in peer-refereed journals and at conference.
In his spare time Robert is a Formula 1 motor racing enthusiast and enjoys outdoor activities especially hill walking and scrambling, golf and fishing. Robert is a brass band enthusiast, a tuba player and band manager of Hatfield and Askern Colliery Band. When time allows Robert also enjoys travelling and reading any books associated with travel and popular science.
