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

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