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 prices are falling fast, especially with thin-film technology. From early $27 per Watt Peak (Wp) prices to an expected $1 in the near future. At $1 Wp, grid parity will have been achieved in Photovoltaics (PV) and will be able to compete with the prevailing price of electricity.
Two types of solar panels are manufactured, expensive ! crystalline silicon types and proprietary thin-film solar panels. Thin Firm CdTe (Cadmium Telluride) is a direct band gap semiconductor, which enables it to convert solar energy into electricity more efficiently (i.e., more watts per kg of material) than the indirect band gap semiconductor materials used historically.
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.
Thin Firm CdTe (Cadmium Telluride) modules to generate relatively more electricity under high ambient (and therefore high cell) temperatures. Which means it is more efficient should there be high temperatures.
Advanced thin film design produces high energy yield across a wide range of climatic conditio! ns with excellent low light response and temperature response ! coeffici ent. 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.
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. Get a do it yourself solar power kit and experiment utilizing this energy saving technology.
