2. Objective 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?

3. 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)

4. 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.

5. 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.

6. 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
