    3.0 RENEWABLE ENERGY RESOURCES

    Renewable energy is energy which comes from natural

    resources such as sunlight, wind, rain, tides, and geothermal

    heat, biomass etc. which are renewable (naturally

    replenished).

    In 2010, only about 18% of global final energy consumption

    came from renewables (Ref: ).

    The International Energy Agency (IEA) estimates that nearly

    50% of global electricity supplies will need to come from

    renewable energy sources in order to halve carbon dioxideemissions by 2050 and minimise significant, irreversible

    climate change impacts

    Malaysian Energy Policies

    The Energy Policy of Malaysia is determined by the Malaysian

    Government, which address issues of energy production,

    distribution, and consumption. The Department of Electricity

    and Gas Supply acts as the regulator while other players in the

    energy sector include energy supply and service companies,research and development institutions and consumers.

    Government-linkedcompanies, Petronas and TNB are major

    players in Malaysia's energy sector.

    Governmental agencies that contribute to the policy are theMinistry of Energy, Green Technology and Water (KeTTHA),

    Energy Commission (Suruhanjaya Tenaga)), and the Malaysia

    Energy Centre (Pusat Tenaga Malaysia).

    Sustainable development of the energy sector is important in ensurin

    competitiveness of the economyEfforts will be undertaken to manage

    both depletable and renewable energy resources to cater for the

    demand of the economy;

    To supplement the conventional supply of energy, new sources such

    as renewable energy will be encouraged.Of these, biomass resources

    such as oil palm and wood waste as well as rice husks, will be used on a

    wider basis mainly for electricity generation. Other potential sources

    include palm diesel and hydrogen fuel.

    Achievement

    9MP targeted the production of 350MW of grid-connected electricityfrom renewable sources, translating into 1.8% of electricity mix.

    However, only 53MW was achieved by the end of 2009, or 15% of thetargeted capacity, he said.

    The 10th Malaysia Plan (10MP) re-emphasised the use of renewableenergy to meet Malaysias growing energy demands, in particular hydropower for electricity generation and blending of biofuels for transportsector.

    Two of the steps taken by the Government to help boost development inrenewable energy sector is the plan to implement a feed-in tariff

    programme later this year and the mandatory blending of biofuels fortransport sector in 2011.

    The Potentials of Solar Energy

    Solar energy represents an abundant and unlimited resource, which

    theoreticallycould supply all the worlds energy demand. The Earths' surface receives so much solar energy from the sun everyday,

    that if this energy is harnessed for even just 60 seconds, it would be enough

    to power the world's total energy requirements for a year

    The Sun radiates energy at 3.91026 W, but energy received at the outer

    atmosphere of Earth is 1368W/m2. This value varies in 1.7% due tochanges in the EarthSun distance

    The maximum radiation is received during a sunny day, where 90% of the

    extraterrestrial radiation become direct radiation while the rest are being

    deflected as diffuse radiation, while conversely, on a cloudy day, nearly all

    of the solar radiation is diffused Although solar energy is sufficient to meet the entire energy needs of the

    world, currently it is not economical to do so because of the low

    concentration of solar energy on earth ( W/m2) and the high capital cost of

    harnessing it due to low conversion efficiency.

    Typical Solar variation (temperate regions)

  • 7/31/2019 Solar energy resource intro

    45/117

    A tropical country such as Malaysia is generally hot all year around and

    experiences its rainy season during the end of the year. With an average of

    12 h of sunshine daily, the average solar energy received is between 1400

    and 1900kWh/m2 annually.

    Although Malaysia has high potential in solar electricity generation, the

    present initiatives and efforts are lower than the countrys actual

    potential.

    Currently, the solar energy conversion status in Malaysia is 1 MW, and its

    estimated potential can reach more than 6500 MW [14].

    Solar Energy Technologies

    Solar Energy Technologies are characterized by how Solar energy could be

    harnessed, either passive solar or active solar depending on the way they

    capture, convert and distribute solar energy.

    Active solar technologies increase the supply of energy and are

    considered supply side technologies, while passive solar technologies

    reduce the need for alternate resources and are generally considereddemand side technologies

  • 7/31/2019 Solar energy resource intro

    47/117

    Active Solar Techniques

    Active solar techniques include the use ofphotovoltaic (PV) panels , solar

    thermal collectors and concentrating solar power to harness the energy.

    Other than PV systems, Active solar energy systems collect, store and

    distribute solar energy by use of mechanical devices such as pumps or

    fans. When air or water is warmed by the sun, the active system circulates

    the warmer air or water, replacing the medium in the collection devicewith cool water or air, which is then warmed and cycled through the

    system again.

  • 7/31/2019 Solar energy resource intro

    48/117

    Passive Solar Techniques

    Passive solar energy systems harness the sun's light and heat directly,

    without employing devices to capture and convert it to electricity include

    orienting a building to the Sun, selecting materials with favorable thermal

    mass or light dispersing properties, and designing spaces that naturally

    circulate air.

    One example of passive solar energy is the placement of windows to allowoptimal amounts of sunlight into a room or building, both lighting and

    heating the area without the need for an external energy source.

    Passive solar energy can also be used, within a building, to create air

    currents, which work with the ventilation system to cool as well as provide

    heat.

    3.1.1 Photovoltaics (PV)

    Photovoltaics (PV) is a method of generating electrical power byconverting solar radiation into direct current electricity usingsemiconductors that exhibit the photovoltaic effect. Photovoltaic solarcells convert solar energy into electricity by using photons of light to knockelectrons into a higher state of energy.

    A solar power cell consists of two layers of this treated silicon. The bottomlayer is positively charged (P-type) and the top layer is negatively charged(N-type).

    The two layers form an electric field between them which only allows theelectrons to flow from the P-type silicon to the N-type silicon.

    When the solar power cell is part of an external circuit, this will allow it to

    generate solar electricity when light strikes the top silicon surface Materials presently used for photovoltaics include monocrystalline silicon,

    polycrystalline silicon, amorphous silicon, cadmium telluride, and copperindium selenide/sulfide.

    ..Photovoltaics (PV)

    Photovoltaic power generation employs solar panels comprising a numberof cells containing a photovoltaic material

    Photovoltaic systems are more versatile than other solar energy systems

    and their popularity among solar power researchers and enthusiasts has

    created a faster rate of advancement and development.

    Photovoltaic solar energy systems are used in consumer, commercial and

    industrial applications, which use the direct production of electricity to

    power lights, cooling systems, ventilation and many other applications.

    Due to the growing demand for renewable energy sources, the

    manufacturing of solar cells and photovoltaic arrays has advanced

    considerably in recent years.

    Types of Solar PV

    Most solar panels can be classified as : monocrystalline, polycrystalline oramorphous based on the silicon structure that comprises the cell.

    Different panels use different materials that display the photovoltaic

    effect.

    Each has different sensitivity to light and temperature and may have

    different cell designs which affect the overall look

    Solar panel efficiency is still only about 13-18% efficient in turning sunlight

    into electricity.

    wattage per square metre though more expensive, thanpolycrystalline types. Hence not necessarily the first choice forevery home

    Very slow degradation, generally losing 0.25 - 0.5% per year

    The lifespan of a monocrystalline cell is a minimum of 25 years andcan be upto 50, i.e. worthwhile investment for long term use.

    The average size 180 W panel is about 160cm length, 80 cm inwidth, 3cm high, and weighs 15kg with its aluminum frame.

    Extremely fragile,that means a rigid mounting is a must

    Polycrystalline PV panels

    Similar to mono-crystalline panels, but the silicon used has a differentstructure which is easier to make and therefore cheaper to buy and installthan mono-crystalline panels.

    perform a bit better in high temperatures.

    Poly-crystallines are slightly less efficient, so more panels may be needed forthe same output.

    Amorphous PV panels

    Less expensive than the crystalline panels. If space is not an issue, than an

    amorphous panel could be a great option. Perform better than crystalline panels in very hot temperatures and are alsoslightly more tolerant of partial shading.

    The production process is more energy efficient than the other panel varietiesso the panels are generally cheaper to make and to purchase. Their lightweight makes them suitable for curved structures.

    They have a lower energy generation efficiency, so the panel is typically nearlydouble the size than the other panel varieties

    Thin film has improved shade and temperature tolerances over both monoand poly and has better embodied energy rates than both.

    Types of PV Solar Energy Systems

    PV Stand-Alone (off-grid) Systems These are designed to operate independent of the electric utility grid, and

    are generally designed and sized to supply certain DC and/or AC electrical

    loads. Stand-alone off-grid systems can be applied to remote homes, lighting,

    TV, computers, water pumps and greenhouse ventilation systems

    The output of an off-grid system is entirely dependent upon the intensity ofthe sun. The more intense the sun exposure, the greater the output. The

    electricity generated is used immediately, so the system must function on

    direct current and variable power output

    The simplest type of stand-alone system is a direct-coupled system, where

    the DC output of a solar module or array is directly connected to a DC load. If a certain power output guarantee is required at any time of the day or

    night, either some kind of storage device is necessary. Most off-grid systems

    use batteries to store power during periods of low to no sunlight .

    The systems may be powered by a solar array only or may be combined with another energy

    supply such as wind turbine, propane or a diesel generator as an auxiliary power source in

    what is called a solar-hybrid system (see hybrid systems). To meet the largest power requirements in an off-grid location, the PV system can be

    configured with a small diesel generator. This means that the PV system no longer has to be

    sized to cope with the worst sunlight conditions available during the year. Use of the diesel

    generator for back-up power is minimized during the sunniest part of the year to reduce fuel

    and maintenance costs.

    PV Grid-Connected Systems

    In grid-connected or grid-tied systems, solar energy is used during the day by

    the system owner. At night, the user draws on the previously establishedelectricity grid.

    An addition benefit of the grid-tied system is that the solar system does notneed to be sized to meet peak loadsoverages can be drawn from the grid.

    Surplus energy generated during the day can be exported back to the grid.

    Grid-connected systems must meet utility requirements. For example,

    inverters must not emit noise that can interfere with equipment reception. Grid-connected systems can be applied to residential installations

    PV Stand-Alone Grid-Tied Systems

    Stand-alone grid-connected systems are the same as grid-connected systems,except with battery storage added to allow power to be generated even if theelectricity grid fails.

    Stand-alone grid-tied systems can be applied to residential and businesssystems that require uninterrupted power

    A "Grid-tie" solar system is useful for homes that are already connected to

    the utility grid. The advantage of this type of system is the price reductionof utility. The system has to be wired with an inverter that produces pure-

    sine-wave AC electricity, which is necessary for connecting to the utility

    grid.

    3.1.2 Solar Thermal Energy

    Solar thermal energy (STE) utilizes solar thermal collectors tocollect heat, which can then be transferred to air and water-

    heating systems.

    STE collectors are similar to photovoltaic collectors in

    appearance, but operate by collecting and distributing heatthrough fluid-filled pipes to provide solar space heating and

    solar water heating.

    g ( ) Concentrating Solar Power (CSP) systems utilize lenses, mirrors and

    tracking systems to focus large amounts of sunlight into smaller areas. The

    focused sunlight can then be used either as a direct source of heat, or to

    boost the effectiveness of photovoltaic systems.

    3.1.4 Passive Polar Systems

    Passive solar energy systems harness the sun's light and heatdirectly, without employing devices to capture and convert it

    to electricity include orienting a building to the Sun.

    Daylighting is simply designing a space to use as much natural

    light as possible. This decreases energy consumption andcosts, and requires less heating and cooling from the building

    A good daylighting design can save up to 75 %of the energy

    used for electric lighting in a building.

    Electric lights also generate significant heat in a building andby turning off or dimming the lights when not needed, 10 to

    20 %of the energy used to cool a building can be saved ( -ve

    for hot regions, +for cold regions)

    Harnessing solar energy has been limited. The largest solar installations are solarwater heating systems in hotels, small food and beverage industries and uppermiddle class urban homes.

    A third of the Government's total allocation of RM469 million for ruralelectrification programmes under the Seventh Malaysia Plan has been allocatedfor the provision of solar powered installations for rural and remote communities.

    A 100 kWp Demonstration Photovoltaic Project was implemented under the

    initiatives of the Ministry of Energy, Water and Communications, and the JapaneseGovernment, represented by NEDO in Marak Parak, Sabah. The project wascompleted in 1995. The project has given the necessary beginning for the effectiveand efficient transfer of technology in the field of PV power generation.

    There is also a demonstration project 17,500 KWh per year 'Hybrid Solar PV -Diesel at Nature Education and Research Center (NERC) at Endau RompinNationalPark, Johor, Malaysia.

    At the end of 2008, Malaysia had cumulative total installed and commissionedgrid-connected PV capacity of approximately 740 kWp and off-grid PV capacity of7-8 MWp. The off-grid PV applications serve mainly rural electrification and non-building structures and are almost fully funded by the Government of Malaysia

    3.1.7 Economics Assessment

  • 7/31/2019 Solar energy resource intro

    106/117

    The cost of home solar power systems have continued to change over the past decade due to

    changing Government incentive schemes, technology advancements in panels manufacturing

    and inverter efficiency, and suppliers in the market.

    Cost considerations

    The price of your solar PV system can be affected by variables including:

    Government rebates and support schemes (these vary in each state)

    Location

    Number of panels

    Orientation of panels

    Type of panels

    Type of inverter

    System design and configuration

    Shipping costs for equipment and parts Contractor installation costs

    Removal of trees or other shading

    Site preparation needs (for example, condition of roof or ground)

    Structural engineering, architectural, and other professional services (for commercial systems)

    Cost considerations

  • 7/31/2019 Solar energy resource intro

    107/117

    Cost considerations

    It is also important to note that if you have a solar PV system installed,your electricity rates will change from an off peak tariff to a time-of-use

    (TOU) tariff. This will particularly affect your dedicated off-peak loads, such

    as hot water, space heating and air-conditioning.

    You should check with your electricity retailer whether the benefits of the

    time-of-use (TOU) tariff outweigh the benefits of staying on your off-peaktariff. This needs to be considered before your install your solar PV panels.

    Government rebates such as Renewable Energy Certificates can be

    deducted from these figures.

    Example: Cost considerations

  • 7/31/2019 Solar energy resource intro

    108/117

    Example: Cost considerations

    1 kW peak solar system generates around 1,600 kilowatt hours per year ina sunny climate and about 750 kilowatt hours per year in a cloudy climate.

    A solar energy system can provide electricity 24 hours a day when thesolar electric modules are combined with batteries in one integratedenergy system.

    Solar modules produce electricity even on cloudy days, usually around 10-

    20% of the amount produced on sunny days. The typical components of a solar home system include the solar module,an inverter, a battery, a charge controller (sometimes known as aregulator), wiring, and support structure.

    A typical silicon cell solar module will have a life in excess of 20 years

    Cost estimation (example)

    Some basic figures about the power resource from direct sunshine. On a cloudless midday it could equate to1000W/m. This needs to be corrected according to the angle of tilt between the surface and the sun. A majorcorrection being the latitude on earth from the equator. (So, for example, in London at 51 degrees north wouldbe about a 60% reduction to being on the equator. It would be further reduced by the season of the year andfurther still for cloud cover. On average the sun shines about 34% of daylight hours in London) The combinedeffect of these three factors is that the average raw power of sunshine per square metre of south facing roof inLondon is roughly 110W/m.

    Some rough estimates of the potential power we could harness from the sun.

    The two most common domestic solar power options are Solar Thermal and Solar Photovoltaic'

    Solar Thermal utilizes the simplest technology by heating water directly.Let's say we have 10m of south facing solar thermal panels and these are 50% efficient in converting thesun's 110W/m into hot water.50% x 10 m x 110W/m which would deliver 13kWh per day

    Solar Photovoltaic (PV) panels convert sunlight into electricity.Typical solar panels have an efficiency of about 10%, the more expensive ones could be higher than 20%efficient.An average south facing 20% efficient photovoltaic panel in England would be20% x 10m x 110W/m = 22W/m which would deliver 5KWh per day

    Solar power technology is improving consistently over time, as people begin to

    understand all of the benefits offered by this technology.

    Advantage:

    Solar energy is a completely renewable resource.

    Solar energy system make absolutely no noise at all. There are no moving parts in

    a solar cell.

    Solar power is pollution-free during use. Production end-wastes and emissions are

    manageable using existing pollution controls. End-of-use recycling technologies

    are under development and policies are being produced that encourage recycling

    from producers.

    PV installations can operate for many years with little maintenance or intervention

    after their initial set-up, so after the initial capital cost of building any solar power

    plant, operating costs are extremely low compared to existing power technologies.

    Solar cells tend to last a good long time with only an annual cleaning to worry

    about.

    Solar panels and solar lighting may seem quite expensive, but in the long run it is

    saving quite a great deal of money.

  • 7/31/2019 Solar energy resource intro

    112/117

    Advantages Solar powered panels and products are typically extremely easy to install. Wires,cords and power sources are not needed at all, making this an easy prospect toemploy.

    Solar electric generation is economically superior where grid connection or fueltransport is difficult, costly or impossible. Long-standing examples includesatellites, island communities, remote locations and ocean vessels.

    When grid-connected, solar electric generation replaces some or all of the highest-cost electricity used during times of peak demand (in most climatic regions). Thiscan reduce grid loading, and can eliminate the need for local battery power toprovide for use in times of darkness. These features are enabled by net metering.Time-of-use net metering can be highly favorable, but requires newer electronicmetering, which may still be impractical for some users.

    Grid-connected solar electricity can be used locally thus reducing

    transmission/distribution losses experimental high efficiency solar cells already have efficiencies of over 40% in

    case of concentrating photovoltaic cells and efficiencies are rapidly rising whilemass-production costs are rapidly falling.

    Disadvantages

  • 7/31/2019 Solar energy resource intro

    113/117

    Photovoltaics are costly to install. While the modules are often

    warranteed for upwards of 20 years, much of the investment in a home-

    mounted system may be lost if the home-owner moves and the buyer putsless value on the system than the seller.

    Solar electricity is not produced at night and is much reduced in cloudy

    conditions. Therefore, a storage or complementary power system is

    required.

    Solar electricity production depends on the limited power density of thelocation's insolation. Average daily output of a flat plate collector at

    latitude tilt in the tropic the is 37 kwh/mand on average lower in

    Europe.

    Solar cells produce DC which must be converted to AC (using a grid tie

    inverter) when used in existing distribution grids. This incurs an energyloss of 412%.
