the heat from the panel into a storage tank where water can be heated. The storagetank provides an insulated area to maintain the heated water and a heat exchanger toheat the water required for domestic and home heating. Most systems are simpleenough for people with some basic skills to set up the system themselves. However,qualified installers are available to ensure these systems are properly configured.(SolCan solar panel example)When it comes to the actual solar panels a variety of systems exist. There arethermosiphon based systems that drain the water fro m the panels in the event ofcold that might freeze the water in the panel. Other systems that may be moreeffective in colder climates are based on vacuum tube based collectors in the panels.Since a vacuum provides an excellent insulation property these systems may provemore efficient and effective in colder climates where the temperatures outside mayreduce the heating effects as the heat is transferred from the panel to the indoorstorage tanks. (Schott solar panel examples)Electricity Generation from Solar PowerThe system plants use to convert sunlight into energy /food for growth is one of thegreat miracles of nature. Although we have not yet become as sophisticated asplants at this process, weve made some progress in the form of Ph otovoltaic solarpanels, wind turbines, wave turbines, geo thermal systems, heat pumps, and windmills. Converting energy supplied by the sun which in turn drives the weatherpatterns on earth that create wind and waves, for instance, seems as natural as itcomes. In fact we have been trying to mimic nature for thousands of years. When itcomes to tapping into the mechanical energy embodied in wind and river watermovement, innovations continue. The invention of turbines provided the morerecent capability of transforming wind and running water into electricity. Turbinesare the result of our recent understanding of the properties of electricity. Wevelearned to capture the energy in the wind and water by imposing a prope ller intothese environments that spinning wires tightly wrapped around metal posts, andmagnets. Recently, in part due to the space program, there have been innovations inthe form of silicon chips that allow sunlight to directly induce an electrical current.Photo Voltaic (PV) Solar PanelsGenerating electricity from sunlight is a fairly recent innovation that came out of theUS space program. These systems use a property of silicon configured in a special166
way to convert sunlight into electricity. These solar panels are able to then transferthis electricity in direct current (DC) form (the type of electricity typical of batteries)for use by DC devices or to batteries for storage. In order to use the electricity withconventional alternating current (AC) appliances and devices an inverter is required.An inverter is an electronic device that is cable of converting DC current beinggenerated or provided by solar photovoltaic panels, wind turbines or other DCgenerators into AC electricity in real time, on demand. In situations where part ofthe goal is to supply excess electricity back into the electricity grid, the inverterprovides the capability of matching the quality of AC power required. In addition,the inverter is a critical component in ensuring that power is not sent to the grid, ingrid -tied environments, when the grid system fails. This protects the line workersthat may be repairing the system from the dangers of potential electrocution.Inverters specifically certified for this grid-tied purpose are required. Other fail safeoptions exist with grid tied connects for manual disconnection from the grid.Wind Turbine ComponentsR Wind tur bineR Tower of typically 40-60 feetR Wiring to electrical systemR Inverter to convert DC to AC ( some wind turbines generate AC at the tower)R Optional: Batteries for backup powerPV Panel ComponentsR Solar photovoltaic panelsR Wiring to electrical systemR Inverter to convert DC to ACR Optional: Batteries for backup powerOther Renewable Energy SystemsR Water turbine167
