| Solar Panel Kits Home Page Solar Panel Modules, Thin Film Solar Panels vs Crystalline SiliconSolar power systems form a vital part of any home emergency survival kit. Solar power kits may help in life saving emergencies, natural catastrophe, or any other emergency where you could be cut off from the power grids but you have a need for electricity. 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. How to Build Solar Panels, Want to learn more?

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 lowest thin film module price is at $2.49 per watt (€1.89 per watt) from a Germany-based retailer. As a general rule, it is typical to expect thin film modules to be at a price discount to crystalline silicon (for like module powers). As thin film manufacturers expand production, prices are expected to drop dramatically. Solar cells become less efficient at converting solar energy into electricity as their cell temperatures increase. However, the efficiency of Thin Firm CdTe (Cadmium Telluride) semiconductor material is less susceptible to cell temperature increases than traditional semiconductors. 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. The measurement of kilowatt-hours per kilowatt installed is an important factor. Calculate the average total solar watt output per dollar outlay. In most cases, when you are reach $0.15/kWh or better, you are competitive with your electric company. The kilowatt hour is a convenient unit for electrical bills. 48- volt systems are a lot more expensive overall to setup. There are battery banks, inverters and cabling costs to consider. Still they are are a lot more efficient that 12v systems. A 1000w system would produce about 4 Kwh per day. Energy usage of a typical electrical customer in one month is several hundred kilowatt hours. Most families use between 4-9 Kwh per day.
