• Different Types of Solar
  Systems
   Types of Solar Panel


• Solar Hot Water Heater
  System and your home
   Cost of installing and lifetime


• How it would effect your life
   Money saving
   Huge change in your lifestyle?
      Types of Panel

• Flat-plate collectors
    Insulated metal box with glass
    and glazing cover and a dark-
    coloured absorber plate. Heats at
    less than 82°C(180°F)
     Types of Panel

• Evacuated-tube collectors
   Glass tubes with selectively
   coated absorbers inside
   transferring energy to heat.
   Most efficient at above
   82°C(180°F).

• Concentrating collectors
    Concave mirror with focal point
   directed to an absorber or
   receiver. Can reach higher
   temperature than Flat-plate and
   evacuated-tube collectors.
     Your home and the
           system
• Installation varies depending on size of
  family, tanker, and solar system; type of
  roof, building codes, and collectors.
  Usually range from $1,500 to $3,000.

• Some states offers rebates to reduce
  costs.

• Example, family of four saves up to
  85% yearly.

•   Can heat swimming pools and hot tubs.

• Long lasting parts and easy
  maintenance.
               Lifestyle
• Cannot totally replace conventional
  boilers but enough to save significantly.

• Best results for hot water around late
  morning and early afternoon.

• Hot water use should be spread out
  over a week so solar system can be
  most efficient.

• Lower mortgage rate.

• Better environment.

• Still effective in colder climates
