How I built an electricity producing Solar Panel So using bigger cells produces more power, but the panel will be large and heavy. Using smaller cells keeps the panel small and light, but won't produce as much power. Also, mixing cell sizes is not a good idea. This is because the current your panel can produce will be limited by the smallest cell in the group and the larger cells won't work to their full potential, pdf file

Make your own blackberry juice solar cell With iodine, blackberry juice, and a few simple materials, you can create a working solar

Sun path chart program This program creates sun path charts in Cartesian coordinates for: (1) "typical" dates of each month (i.e.; days receiving about the mean amount of solar radiation for a day in the given month); (2) dates spaced about 30 days apart, from one solstice to the next; or (3) a single date you specify. You can select whether hours are plotted using local standard time or solar time, Solar radiation estimation

Geosource Heat Pump Handbook What is a heat pump? A heat pump is a mechanical device used for heating and cooling which operates on the principle that heat can be pumped from a cooler temperature to a warmer temperature (cold to hot). Heat pumps can draw heat from a number of sources, eg, air, water, or earth, and are most often either air-source or water-source, pdf file
