PV STREET LIGHTING

General presentation:

The street lighting system can be realised in two

ways:

• First, using a photovoltaic plant that will

be the core of the system and which will

power the lights.

• The second option is to use a complete

single lighting system, one that

contains the photovoltaic panel and the

lamp.

Both systems can be used in accordance with the application and the best solution will be chosen.Thesesystems can be made in the range from 130W to 500kW, depending on the location and the number oflights used.

GEOTHERMAL HEAT PUMPS

The geothermal heat pumps provide low cost energy and a high level of comfort becausethey rely on the natural thermal energy from the Earth. These systems require a small amount ofelectricity for heating or cooling in order to achieve a small price maintenance for the livingspace.

These systems are used for single or multifamily homes, hotels and motels, shops,

shopping centers, gas stations, office buildings, hospitals, banks and schools.

OperationHeat pumps have an underground piping system that circulates a fluid (usually a mixture

of water and antifreeze). During winter, the fluid captures the soil temperature, and then

transports it to the building heat pumps which concetrate this temperature and distributes it on to

residential areas to warm them.

In summer, the process is reversed, the heat inside the building is absorbed by the heat

pump and then dispersed into the ground. This excess heat can be used for domestic water

heating. Depth at which pipes are inserted (180 cm) provides a constant temperature between 8

and 12 ° C throughout the year.

The efficiency

• Geothermal systems have the lowest operating costs of the existing residential andcommercial air conditioning field. Unlike an electric air conditioning system, costs are reducedby 70%, 50% compared to the costs implied by the air source heat pumps.

• For the systems that use fossil fuels, costs are reduced by 70% and the cooling processfor the buildings saves 90%.

• The coefficient of performance of geothermal heat pumps is 3.5 to 6, which means thatevery unit of electricity fed into the system gets 3.5 to 6 units of energy in the building, as 3.5 to4 units energy from Earth, for Free.

The advantages of the geothermal systems

• The savings made compared to any classical system used• Protection and natural resources economy• Environmental protection• No danger of explosion• Noise free and do not require expensive maintenance• High reliability• Purchase prices are around 3-5 Euro / W• Depreciation expenses in 5-7 years

SUN COLLECTORS

The operating principle of such a device is represented by capturing the solar power into a fluidwhich is then used to heat water.

The main advantages are:

• direct conversion of solar thermal energy• high solar energy conversion efficiency, up to 60%• purchase price is about 200-500 EURO/m2.
