How Does Solar Power Work? Solar Panels (photovolatic cells) convert the sunlight into electricity. The cells are grouped together to create solar panels. A series of panels can be linked together and tied into the rest of your solar system to generate enough power to reduce or eliminate your electricity bill. A residential PV solar system enables a homeowner to generate power during the day when they are not at home and sell the excess energy to the utility grid at peak rates. In the evening, when rates are less expensive, the homeowner then draws electricity back from the grid to power their homes. This basic concept is called net-metering or time of use metering. You can get the electricity you need just from the sun. 1: Large rectangular panels made of photovoltaic (PV) cells are installed on your roof, which generally has direct access to sunlight and is out of the way. These panels PV cells take the light from the sun and convert it to direct current (DC) power. 2: The power you use in your home is AC or alternating current, so an inverter is installed to convert the power from DC to AC. The converted power travels through the connections to the breaker box and is now ready to be used to run your TV, microwave and serve every other electrical need you have. 3: The breaker box or electrical panel is usually where your power meter is. This meter will measure your electricity use. When your solar panels are producing more electricity power than you need, the excess power will be sent to the utility company’s power grid, this will cause your power meter to begin spinning backwards. This backward spin begins crediting your account instead of adding to your bill. At night when you need power, you will draw power from the grid, just like you are doing now, but you will be offsetting the cost by using the credits you accumulated when your power meter was spinning backwards. The goal is to generate enough power during the day for your use and to “sell” enough power to the utility company to cover most of your night time use.
Solar PV Arrays Photovoltaics Multiple Solar PV modules can be wired together to form a Solar PV array. Solar PV modules and arrays produce direct current (DC) electricity. They can be connected in both series and parallel to produce any required voltage and current combination
  Building Integrated PV What are Solar PV Arrays? Because a single Solar PV panel can only produce a limited amount of power, many installations contain several panels. Solar PV panels that are electrically connected together are often referred to as an array.
  Solar PV Panels A grouping of Solar PV panels can be fitted in different configurations depending on the local conditions e.g. to follow the shape of a roof or to avoid a roof light. Solar Panels usually have a backing sheet that is opaque but the backing can be transparent, allowing some light through and creating a dappled effect.
  Solar PV Arrays – Photovoltaics Solar PV requires only daylight, not necessarily sunlight, and is therefore capable of generating electricity on cloudy days. Solar PV works equally well in urban or rural locations. It can be installed on the roof of most homes that can support the equipment and can be easily connected to a building’s electricity supply.
  Sunlight for Solar PV Arrays The amount of available sunlight in the UK varies with the latitude of the site. The south of the country has more available light than the north. The total annual energy available varies from approximately 1,259 kWh per metre squared per year in the South-West of England to 850 kWh per metre squared per year in Scotland. The light energy also varies during different seasons of the year with more daylight available in the summer than in the winter.
  Solar PV Atrium – Building Integrated Solar PVSiting of Solar Integrated PV – Solar PV Arrays Solar PV panels can be attached to pitched roofs or flat roofs, fixed vertically onto external walls or located on the ground. They can also be integrated into patent glazing or rain screen cladding systems. They should work efficiently in most locations as long as no part of the panel is shaded from daylight.
  Solar PV – Crystalline Silicon Panels By far the most prevalent bulk material used in the manufacture of Solar PV Panels is crystalline silicon. Bulk silicon is separated into multiple categories according to the crystallinity and crystal size in the resulting ingot, ribbon or wafer. Currently popular solar cells are made from bulk silicon that is cut into wafers between 180 to 240 micrometres thick.
  Solar PV – Solar Thin Film Solar Thin Film technologies reduce the amount of material required to create a solar cell. Thin film silicon cells are becoming increasingly popular because of their low cost, flexibility, lighter weight and ease of integration into building materials and buildings. When in use, Solar PV does not generate greenhouse gases or cause pollution. Each kilowatt-peak (kWp) of electricity produced can save approximately 455 kilograms of carbon dioxide emissions compared with electricity generated from fossil fuels
  Solar PV – Solar PV Panels – Photovoltaics Solar PV Panels convert photons of light to electrical energy using a semi-conductor material; the most common being crystalline silicon. When daylight shines onto a Solar PV cell, electrons are released causing electricity to flow. The amount of solar electricity produced depends on the intensity of the light received by the Solar PV cells
  Tilt Angle of Solar PV Panels Solar PV PanelsSolar PV Panels will operate at maximum efficiency if they are orientated towards the south. The most efficient tilt angle can be calculated by subtracting 20° from the geographic latitude. Therefore, an installation in London, latitude of 51°, the optimum tilt is (51 minus 20) 31° from the horizontal.
  Solar PV Panels – Installation The installation of Solar PV Panels causes minimum disruption to the home and systems can be retrofitted. A typical silicon cell is quite small, in the order of 100mm x 100mm square. Solar cells produce electricity at low voltage but when more power is required a number of cells can be connected together to create Solar PV Panels.
  Solar PV Panels – Solar PV Tiles Solar PV tiles are Solar PV Panels that are manufactured to a shape that can be integrated into a normal tiled roof. The top of the solar tile is hidden under the tails of the row of tiles above it, so only its exposed area contains the Solar PV cells. The solar tiles are connected together electrically in arrays and have the same characteristics as the solar panels already described. Solar tiles can make a cost saving as they take the place of ordinary roof tiles.
  Stand-Alone Solar PV Panels Stand-alone Solar PV Panels are useful where there is no connection to the local electricity network or where the mains power supply is prone to interruptions. If the installation is for a home that is not connected to the local electricity supply network, then the Solar PV Panels can be configured to directly charge a bank of batteries. The power flow from storage batteries is direct current (DC) that can be converted to alternating current (AC), mains power, by the installation of an inverter.
  Solar PV Panels – Mains System Energy supply companies are obliged to acquire a percentage of their energy from renewable sources, to help cut carbon dioxide emissions. By purchasing the surplus electricity from a Solar PV Panels system, energy suppliers are able to fulfil this requirement. During daylight hours, the electricity generated by the Solar PV Panels will supply the home and any surplus will be sold to the nominated electricity supply provider through an approved import/export meter. During periods of high energy use in the home, or when the Solar PV Panels are unproductive, electricity can be bought back from the network to supplement the Solar PV power supply.
  Solar PV Panels – Solar CellA Home’s Energy Requirement An average family in the UK uses between 2,000 and 4,000 kilowatt hours of mains electricity per year. A typical domestic Solar PV Panel system of between 1.5 kilowatt-peak and 2 kilowatt-peak will provide 30 to 40 per cent of the total electricity requirement. If the house is already energy efficient then the solar power percentage will be higher.
  Solar PV Panels – Installation in a Home Solar PV Panels should always be installed by a trained and experienced installer. Electrical safety regulations cover Solar PV Panels and should be adhered to by the installer.
  Planning Consent for Solar PV Panels National planning guidance urges local planners to take into consideration the need to develop more renewable energy in their regions. Planning permission is usually only required for the installation of Solar PV Panels on listed buildings or buildings in conservation areas. In all circumstances it is advisable to discuss the planning issues with the local authority before having Solar PV Panels installed.
  Maintenance of Solar PV Panel Systems The average life of Solar PV Panels is in excess of 20 years. Crystalline silicon modules have a very long life span and require very little maintenance. Solar PV Inverters will generally need to be replaced after ten years. The maintenance of systems connected to the local electricity network is usually limited to the cleaning of the Solar PV Panels but the wiring and components of the system should be checked regularly by a qualified technician. Batteries in Solar PV Panels stand-alone systems should last between 6 and 10 years with regular maintenance, depending on the quality and type employed. If you are not able to install your own Solar PV Panels, you can support renewable energy by switching to a supplier of green electricity
