Solar panels (nr)

  1. 1. SOLAR Panels<br />Niall Rafferty<br />
  2. 2. Solar Energy<br />Renewable energy Sources account for only 1% of total energy used globally<br />Solar energy is the smallest renewable source used worldwide<br />The sun provides over 80 times more energy than the world requires daily<br />We need to take advantage!<br />
  3. 3. Solar Power in Ireland<br />
  4. 4. Solar Panels<br />Simply uses the suns energy to heat water in a dwelling<br />Solar panels can save 60-70% of energy costs in a general Irish dwelling.<br />
  5. 5. Types of panels<br />There are two main types of solar panels used in Ireland;<br />Flat Plate Collectors -copper piping system within a heat absorbing rectangular unit.<br />Quickest Return on Investment (Cheaper)<br />More visually appealing<br />
  6. 6. Vacuum Tubes/Evacuated tube Collectors- A number of vacuum tubes containing a finned-metal collector tube.<br />Capture more sunlight due to greater surface area<br />Better Performance in overcast conditions<br />
  7. 7. The Solar panel system can easily fit into the original service set up in place. i.e. It connects into existing water cistern<br />
  8. 8. Appearance<br />Solar panels can also be aesthetically pleasing<br />Installation on a pitched roof can appear almost like Velux windows<br />Can be integrated into a buildings facade installation<br />

  11. 11. Funding<br />Initial costs are quite high<br />€7000 for a 6m² flat plate collector system<br />Government grants = €250 per m²<br />€9000 for a 5 evacuated tube system<br />Government Grants = €300 per m²<br />The Sun will never send us a bill<br />
  12. 12. Why choose solar panels?<br />Environmentally Friendly<br />Zero Co2 emissions<br />Cheaper in the long run<br />Grants and return on investment<br />Minimal Maintenance required<br />Practical replacement for non-renewable fossil fuels<br />Resources are running out<br />Suitable for Domestic buildings<br />Other forms of renewable energy are not practical <br />
