Photovoltaic (PV) modules
What are they?
Solar panel electricity, also known as solar photovoltaics (PV) is a method of generating electrical power by converting solar radiation into electricity using semiconductors that exhibit the photovoltaic effect. Uses photovoltaic solar panels from solar cells, a photovoltaic material. You do not really need direct sunlight to do this and can still generate some electricity even on a cloudy day. The stored power can then be used to run household appliances and lighting.

Due to the growing demand for renewable energy, the manufacture of solar cells and photovoltaic systems has made progress in recent years. Driven by the advances in technology and increases in manufacturing scale and complexity, the cost of installing photovoltaic modules steadily since the first solar cells were manufactured rejected. In fact, to such an extent, this form of renewable energy is now set more competitive with conventional power sources.
How Solar Panels (PV) cells?
PV cells from layers of semiconducting material, usually silicon. If the cell appears light, it generates an electric field across the layers. The stronger the sunlight, the more electricity produced. Groups of cells are mounted in plates or modules that can be installed on the roof of your home. Most PV systems consist of plates that fit on an existing roof, but you can also fit solar tiles.
PV cells are used in a variety of shapes and sizes. Most PV systems consist of plates that fit on an existing roof, but you can also fit solar tiles.
The performance of a PV cell is measured in kilowatt peak (kWp). This is the rate at which it generates energy at peak performance, in direct sunlight during the summer months.
What are the benefits of using solar panels?
• your electricity costs will be reduced if you have paid for the initial installation;
• Electricity is provided by solar panels, clean and quiet. Because they do not use fuel other than sunshine, PV systems have no harmful air or water pollution in the environment, nor do they deplete natural resources, or endanger the health of humans or animals.
• Photovoltaic systems are quiet and unobtrusive.
• Small solar systems take advantage of unused space on the roofs of existing buildings.
• Solar energy is a locally available renewable resource. It does not need to be imported from other regions of the country or the world.
• A PV system can be constructed to any size based on energy requirements.
• The operator of a PV system can expand the system, based on their energy needs, adding modules every few years, energy consumption and financial resources grow.
• Any unused energy can be sold back to the National Grid, providing faster recovery of investment.
• You can be paid for the electricity you generate, even if you use it!
• Excess power can be sold back to the National Grid, further reducing the cost.
• Reduce your carbon footprint - solar energy is green energy.
The differences between the solar tiles and slates
Solar brick are designed to be used in place of ordinary roof tiles. A system of solar tiles are usually cost about twice as much as an equivalent panel system, although you could save the money spent on tiles or slates. Solar tile systems are usually not as cost effective as panel systems, and are usually only considered where plates are not considered appropriate for aesthetic or planning.
Costs
Cost an average 3 kWp system and around £ 10,000 (including VAT at 5%). Most domestic PV systems cost around £ 3,000 to £ 3,500 per kWp installed, though small systems cost more accordingly. Costs vary between installers, so it is important to get multiple quotes. Other factors are:
• The more electricity the system can generate, the higher the investment, but the more it could save
• Larger systems are more cost effective than smaller plants usually (up to 4 kWp)
• PV modules are all about the same price per kWp, but PV tiles cost much more than a typical system consists of panels
• Panels are built into a roof more expensive than those that sit on the top.
Savings
Can generate A 3 kWp system about 2,500 kilowatt hours of electricity per year - that's around three quarters of a typical household's electricity needs - and save you a ton of carbon dioxide per year!
Maintenance
Solar PV requires little maintenance to keep the panels relatively clean and make sure trees do not begin to overshadow them, is all that is usually required. In the UK panels, which are inclined at 15 ° or more, have the additional advantage that can be purified by precipitation, in order to ensure optimum performance. Debris is likely to accumulate if you have free disk space installations. Consult your installer for exact maintenance is recommended that before you commit to the installation of a PV system.
With proper care, these panels should last for more than 25 years.
Deciding on the best location for your panels and the granting of planning permission
Of course you will want to choose a site for your PV panels that provide maximum performance. Building permit or a building permit is generally not required, but it is advisable to always check with your Local Authority.
