Do It Yourself Solar Power Systems Counsel
Price per watt is the primary unit of measurement for the solar energy. Watt Peak (Wp) is the direct current watts output of a solar module as measured under an Industry standardized Light Test before the Solar Module leaves the manufacturers facility.
Solar modules has dropped from around $27 Watt Peak (Wp) in 1982 to around $2.49 Wp today and can be expected to dive much further in the future. At $1 Wp, grid parity will have been achieved and Photovoltaics (PV) will be able to compete with the prevailing price of electricity.
Essentially, there are 2 types of solar panels. The more expensive kind using crystalline silicon and the new proprietary thin-film technology. CdTe (Cadmium Telluride) is the popular favorite thin-film technology favorite.
The National Renewable Energy Laboratory in Golden, Colorado to recognize CdTe’s (Cadmium Telluride) potential for achieving the lowest production costs among current thin film technologies. Because of thin film technology, mass-production of solar panels through the use of machines similar to a printing press, will aid in cutting cost for watt produced.
Thin Firm CdTe (Cadmium Telluride) semiconductor material also converts low and diffuse light to electricity more efficiently than conventional cells under cloudy weather and dawn and dusk conditions. As a result, Thin Firm CdTe (Cadmium Telluride) modules will generally produce more electricity under real world conditions than conventional solar modules with similar power ratings.
Advanced thin film design produces high energy yield across a wide range of climatic conditions with excellent low light response and temperature response coefficient. Frameless laminate is robust and can take a variety of shapes, is cost effective and recyclable as well.
What really matters is the total kilowatt-hours a panel produces. Then calculate the average solar wattage produced per dollar spent. Chances are, when you are reach $0.15/kWh or better, you are competitive with your electric company.
Two 80W panels in series gives you 160 W. You still have the same *current* as you get from one panel, but twice the voltage. There are inverters, battery banks and cabling costs to consider. Most families use between 4 and can run up to 20 Kwh per day for heavy users. A 1000w system would produce about 4 Kwh per day. Build your own solar panel with a do it yourself kit and discover this energy saving technology.
Make your own do it yourself solar power system. Home solar systems can make for an emergency backupsurvival kit. Having a solar backup could be life saving in a natural catastrophe, or any number of instances where you could be cut off from main power but you have an electrical need
