Why Photovoltaics

Solar-generated electricity produces no greenhouse gases or emissions of any kind. Solar energy is a rapidly growing form of electricity generation. There are numerous advantages to using the sun to produce electricity

photovoltaic systems cyprus

For power generation through photovoltaic primarily only two inexhaustible raw materials are needed : sun and sand. The fuel—sunlight—cannot be embargoed. We are not expecting any conflicts about these resources . It promotes security and energy independence. Solar energy does not require import of fuels.
It has fewer environmental impacts than electricity generation with fossil fuel or nuclear power plants. No mining or transportation of fossil fuels are required to generate electricity with the sun. Photovoltaic systems produce electricity without pollution. When operating no waste products are generated.
PV is a source of peak power. Electricity has the biggest value when it is produced at the times of high demand. PV Power plants deliver electricity on daytime, when people work and factories and offices need electricity.

PV is a good combination with Wind Energy. Windpower plants produce most in winter times and in bad weather conditions. PV produces electricity in the summer, when wind plants are often not producing.
Because solar energy is available everywhere , this may make a very good contribution to economic development in less developed areas.

Also for small businesses and individual consumers photovoltaics can represent an economic advantage. When producing electricity on their own roofs , the possibity of cost advantages compared to electricity purchases from the grid appear and make the usage of photovoltaic meaningful.
A few years ago, the electricity production had enjoyed a monopoly almost exclusively in the hands of corporations , who were also operators of transmission networks. Electricity was almost exclusively produced by large scale central power plants .
Today, 15-20% of the electricity is produced locally from renewable sources in a number of European countries. Solar energy contributes significantly in addition to wind energy.

PPR Pipes

 

Interplast PPR pipe and fittings are a hot and cold water supply system suitable for all potable water applications and heating systems. 

PPR pipes and fittings are considered to be the best carrier of potable water, using the revolutionary raw material of PPR-80 of Borouge brand. 

Image result for ppr pipes

PPR pipes are made with reference to the standard of DIN8077/8078 of Germany. 

There are three general types of polypropylene: homopolymer, random copolymer, and block copolymer.

The comonomer used is typically ethylene. Ethylene-propylene rubber or EPDM added to polypropylene homopolymer increases its low temperature impact strength. Randomly polymerized ethylene monomer added to polypropylene homopolymer decreases the polymer crystallinity and makes the polymer more transparent. 

APPLICATIONS 
Residential cold and hot water system 
Underground heating system 
Conveyor of industrial water and chemical materials 
Sanitary and pure water pipelines 
Hot water recycling system 
Compressed air pipelines 
Drink manufacturing and conveying system 
Other industrial and agricultural pipelines

The Benefits of Underfloor Heating

We know that new technologies can be daunting, especially those that may require taking up your flooring, but with all the facts you can now make changes to your home that could save money and provide greater all round comfort. So here we bring you the benefits of investing in either water based or electronic underfloor heating (UFH). Essentially, underfloor heating is not the first choice for standard heating within a home, competiting against the commonly favoured radiators. However, underfloor heating is a method that can provide extra space in a small home, safety, energy efficiency, hygiene, versatility and value.

SPACE

Underfloor heating eliminates the irritating space wasters that are radiators, giving you greater space in bathrooms and other areas that can become cramped. Whilst occasionally flooring may need to be raised for the installation (primarily with water based UFH), underfloor heating is flat and spreads out across a room, hiding from view. UFH introduces areas of your home that were once taken over by clunky metal radiators that can now be utilized for more furniture or room for movement.

Alternatively, you do not have to have underfloor heating in every area of your home as it can be combined with other heating methods. This will allow for space in areas that require it and keep your radiators in other areas. Not only can you have underfloor heating downstairs, but upstairs too.

SAFETY

Secondly to this, underfloor heating is child and animal friendly as it eradicates sharp corners and hot surfaces that could be harmful to babies or pets. There are also no areas where the underfloor heating can leak from, preventing water damage.

ENERGY EFFICIENT

Whilst in recent years, zone based thermostats and temperature based radiator valves have been introduced, an underfloor heating system can be adjusted by room, heating only where is necessary. This essentially saves wasted energy and money by prioritising where is cold.

LOW MAINTENANCE COSTS

Once installed, there are almost no maintenance costs for the system, allowing you to capitalise on the potential 15-30% savings you could make by saving wasted energy.

ADDS COMFORT

Ultimately, whilst there is an initial cost for underfloor heating, it is an indulgent option of heating that offers a vast amount of comfort to a home. Whilst radiators run to high temperatures to emit as much heat as possible, underfloor heating works by releasing a constantly lower temperature that will not get too hot underneath your feet.

Underfloor Heating… What? Why? How?

Underfloor heating is a form of heating in which the floor surface of a space is heated and this heat is then radiated throughout the space to create comfortable thermal conditions. It has been used for thousands of years as a form of space heating, most notably by the Romans, whose hypocaust system consisted of a raised floor through which warm air and smoke were drawn to heat the floor before being discharged through flues.

Modern underfloor heating tends to use either electrical resistance elements or fluid-flowing, hydronic systems to heat the floor.

Underfloor heating systems tend to be low-temperature systems, as the heating surface covers a much larger area than conventional radiators which because of their relatively small size have to operate at a high temperature.

Underfloor heating can be installed on new-build projects, or retrofitted into existing spaces. It can be installed as the primary heating system or used to provide additional, localised heating in specific spaces such as bathrooms. It may be used in combination with renewable heat sources, thermal mass and night-time purging.

Systems can be modular or custom designed and installed, and will generally include insulation under the heat source to reduce heat loss.

Electric underfloor heating systems can sit beneath stone, tile, wood or even carpeted surfaces. A series of electric wires installed beneath or within the floor finish provide the heating element. There are a number of product types available, including loose-fit wiring, modular systems and heating mats.

The design of the installation will depend on the space size and dimensions, how well insulated it is, the nature of the flooring structure and the type of flooring covering. Generally, on new-build projects, cables or electric heating sheets are fitted beneath the floor finish on a layer of screed and insulation which ensure the floor is level and that the heat travels upwards into the space

A fluid flowing hydronic system generally consists of a series of looped pipes connected to a boiler that circulate warm water through the floor. This needs enough space for the installation of piping and insulation and so floor levels may need to be elevated which can be difficult when retrofitting, increasing costs and disruption. For this reason they tend be better suited to new-build projects.

They can be more expensive to install than electrical systems, but may be less expensive to operate.

Because they are low temperature systems, they can easily incorporate renewable energy sources such as solar thermal panels, ground source heat pumps, air source heat pumps and so on.

Photovoltaic Stand Alone System



 

A stand-alone power system is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. Typical stand-alone power system  include one or more methods of electricity generation, energy storage, and regulation. Storage is typically implemented as a battery bank, but other solutions exist including fuel cells. Power drawn directly from the battery will be direct current extra low voltage, and this is used especially for lighting as well as for DC appliances. An inverter is used to generate AC low voltage,

The two types of stand-alone photovoltaic power systems are direct-coupled system without batteries and stand alone system with batteries.

The basic model of a direct coupled system consists of a solar panel connected directly to a dc load. As there are no battery banks in this setup, energy is not stored and hence it is capable of powering common appliances like fans, pumps etc. only during the day. MPPTs are generally used to efficiently utilize the Sun’s energy especially for electrical loads like positive-displacement water pumps. Impedance matching is also considered as a design criterion in direct-coupled systems

In stand-alone photovoltaic power systems, the electrical energy produced by the photovoltaic panels cannot always be used directly. As the demand from the load does not always equal the solar panel capacity, battery banks are generally used.
