CHOOSE THE GOOD SOLAR HEATING SYSTEM NASH TEC

Solar water tank : for your individual solar water heating system installation, the production of warm water is provided for a sanitary use (bathroom, kitchen, shower room, etc..). The volume of your solar water tank depends from the quantity of people living in your home. For 2 people, a solar water tank NASH TEC 150 to 200 liters is recommended, for 4 people please plan 200 to 300 liters, for 6 people 300 to 500 liters, for 8 people 500 to 700 liters, for 10 people 700 to 1000 liters.

For an installation like a combined solar water heating, the production of hot water serves to cover water requirements with hot sanitary water and the heating of your house. We recommend you to double the storage capacity of your solar water tank NASH TEC , or even to triple this capacity if need, according to the internal volume of your house and its level of insulation.

 

A = Solar panels (high pressurized heat pipes vacuum tubes collector) catch the photons of the external natural light. The photons will stay prisoners inside the vacuum tubes, they will release all their energy, until they will disappear definitively

B= Energy is absorbed by the coolant liquid (water + antifreeze liquid MPG). The coolant liquid transfers its calories to the sanitary water inside the solar water tank

C = Heat exchanger coil will warm the cold water

D = Cooled liquid moves again towards the solar panel where it is again heated

E = Inside water tank is a metal tank which contains the warm sanitary water

F = Inlet for cold sanitary water

G = Circulating pump pushes the coolant liquid towards the solar panel. Its operation is ordered by a solar controller which takes in charge the temperature of the sanitary water in the solar tank

H = Solar controller is connected to the sensors of the solar water tank, to the solar panel, to the working station

I = Temperature sensor on the solar panel

J = Temperature sensor on the water tank

K = Additional heat exchanger coil will warm the cold water during the winter, with the warm water flow produced by a gas / wood / fuel boiler, if the quantity of sunny weather is low too much.

 

SOLAR PANEL NASH TEC

You will find mainly 2 types of solar collectors on the market: solar FLAT collectors and solar heat pipes vacuum collectors. The way of working is simple: the present photons in the natural light are captured and will stay prisoners inside the solar heat pipes vacuum collector NASH TEC .

They are going to circulate inside the solar heat pipes vacuum and will release all their energy, until they will disappear definitively. The way of working of the solar heat pipes vacuum panels NASH TEC answers purely to physical laws drawn from the sunlight, the free energy for still several billion years.

 

Specifications of the solar panels :
A flat solar panel is less expensive to be manufactured in a factory than a solar heat pipes vacuum tubes collector. The efficiency of a flat solar panel is in average 30% lower than that of a solar heat pipes vacuum collector.
An impact related to the fall of big hailstones (size of a table tennis ball) destroys definitively a flat solar panel and requires its complete and expensive replacement. In the case of a high pressurized heat pipes vacuum tube solar collector, it is enough to change only each damaged tube for unit costs of 48,00 euros including VAT (price incl. VAT of a complete vacuum tube, with all its internal components, and this spare parts is available at NASH TEC)

Installation of high pressurized heat pipes vacuum tubes solar panels NASH TEC :

The sun is located at a lower level in the sky, in winter that in summer, but it is especially in winter that the need for warm water is the most important. A slope of 45° in summer is recommended for latitudes located at the level of London, Paris, Munich, Vienna, Prague, Bratislava, Budapest. These same cities require a slope of the solar panels with 30° during the winter to obtain the optimal output efficiency. For this reason, we advise you to install your solar panels on adjustable aluminum frames in slope in order to avoid a loss of efficiency of about 30% in winter. For the regions with strong presence of snow in winter, we recommend you to install your solar panels on aluminum adjustable frames in slope on a terrace or in your garden or fixed like a marquee on an external wall. That will enable you to carry out yourself the adjustment of the slope before each winter and each summer, without having to climb on your roof. That will also enable you to cover your solar panels with a simple cover, during the important snowfalls. Lastly, more the solar panels are located close to the ground, more they will benefit from the reflection of the sunlight on snow in winter.
 

WIND ENERGY NASH TEC
The wind energy is interesting financially, on the condition of being able to install oneself its own wind turbine. The more reduced the weight of the generator will be, the more the installation will be easy, less expensive and will be especially practicable by yourself. However, a reduction of the weight of the generator is going to imply a reduction of the maximal output power produced by your wind turbine, because the size of the generator will be also reduced. Now you can start to calculate with an equal tension, if the installation of 2 wind turbines 400W NASH TEC (diameter of the rotor 1.20 meters and unit weight 6,8Kg) will be more economic financially than a 800W single wind turbine (diam. of the rotor 1,80 to 2,30 meters minimum and minimum weight 30 kg).


Choose its charge controller NASH TEC :

A wind or solar controller can work either with a PWM technology (Pulse with Modulation) or with a MPPT technology (Maximum Power Point Tracking). If a PWM charge controller is cheaper than a MPPT charge controller, a PWM charge controller will always be 20 % less efficient than your MPPT charge controller. Moreover, your NASH TEC MPPT controller will always allow to increase the life cycle of your storage batteries, thanks to its technology for charging. We recommend you to choose a NASH TEC hybrid charge controller, it works with a MPPT technology MPPT, its allows you to start with a wind turbine installation with a reduced budget and this wind turbine installation will be completed later on by photovoltaic panels connected to the same NASH TEC hybrid charge controller that you already installed at your home.

 

Choose its power inverter NASH TEC :
2 types of inverters 220 V AC with input 12 or 24 or 48V DC are available on the market: inverter with modified wave and pure sine wave inverter. Inverters with sinusoidal wave (called in English Pure Sine Wave Inverters) are equipped with the most sophisticated technology from today. The quality of the current available on the outlet socket of a pure sine wave inverter is the same than the current produced by the best companies of the public sector. The sinusoidal pure wave is essential to the smooth running of the electric devices equipped with a management by electronic components   (TV with plasma screen / TV with LED technology, refrigerators with electronic management and display of the temperatures, laser printers, electronic devices, sound amplifiers for home cinema and amplified tuners. For these reason, NASH TEC inverters are working with 220V AC Pure Sine Wave technology and are available with 500W to 3000W.
