The governmental tax credit will expire in 2016 December 31. Post date: (08/08/2014) 11:16( GMT-4) I guess if you are a homeowner with limited budget, it might be wise to wait a little bit until the year of 2016 to install your residential solar panel. Because by that time, you probably will be able to get the cheaper solar panel, which is based on thin film solar cell with high efficiency, light weight. In addition, the 30 % tax credit is applied for all kinds of solar cell technology including the thin film solar cell, (https://en.wikipedia.org/wiki/Thin_film_solar_cell) However, if you are financially sound, and willing to improve our carbon-neutral trend for middle-class, I suggest that you can consider purchasing the thin film solar cell based on CIGS, or low cost CdTe solar cell, combined with the proper energy storage system, based on either lithium-ion battery. Actually, a 250W thin film solar cell sit besides the window that facing west direction, that you store indoor, would be a sound choice, to prevent the snow covering during the winter time. This placement of your 250W solar cell, combined with 1kWh battery (assume the battery power your houses computer and small appliance that combine consuming 200 W during the evening hour that you spend at home, which can last approximately 5 hour), can prevent the black out caused by Sandy-level storm. The merit of the off-grid 250 W solar energy conversion and lithium-ion battery storage system is that, you are free from the grid power, that is designed to shut down, during the black-out period. Thus, with this system, your house can truly become energy-independent, which helps for the rescue team to locate your home. Thus, for all the American home, I would really suggest you can DIY an off-gird solar power system that can harvest 250 W power(under the 1000W per square meter standard sun light radiation), in order to be safe. So, all the husbands and wives should really consider equip yourself a little bit knowledge on the solar cell technology, which provide a national-level sense of security. To manufacture all these 250W solar module and 1000 Wh battery, including inverter, battery charge controller, please refer to numerous online sources. However, I really suggest you could spend a few time attending the online lecture provided by Stanford University, Prof. Professor Aneesh Nainani.
