SOLAR WATER HEATING FOR EDUCATION MP2000 (2 DIFFERENTS PANELS)

PRODUCTION of private solar hot water "Pressure" technology

MP2000

Teaching objectives

The study of a solar system of real size for the production of Private Sanitary Hot Water designed with industrial equipment currently in use :

  • Identify the component parts of this equipment and analyze the applicability of the technological choices made,

  • Maintenance and control of the system and implementation of necessary corrective actions, pressure level, anti-freeze protection, primary circuit output

  • Carry out an overall thermal assessment and analyze the instantaneous and accrued thermal output of different sub-groups

  • Analyze the influence of the angle and orientation of the cell

  • Study the technical and economic interest of this method of sanitary hot water production and its environmental impact, calculate the carbon balance of the installation compared to standard electrical water heating

  • With the evacuated tube panel option, a comparison of two types of cell.


Description

 

The bench comprises:

 

A solar panel on casters

  • Flat solar panel with adjustable angle

    • total surface 2.57 m²

  • Connections through double-seal self-sealing joints

 

An evacuated tube solar panel installed on casters,

Equipped identically to the flat panel,

This option enables a comparative study of two types of panels,

It is possible to equip the bench with this option at a later time.
