Solar Water Heating For Education (2 Differents Panels) Manufacturer

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.
