Taxable and Non-taxable Allowances. Iâve noticed some questions on Yahoo answers about which allowances are taxable and which are not. At the current time, the only taxable allowance is CONUS COLA, the Cost of Living Allowance paid to people who living in certain expensive parts of the continental United States. By federal law, all new allowances created after 1986 will be taxable.
Solar shingles vs. solar panels. Many homeowners are curious about the difference between solar shingles and traditional solar panels. Solar roof shingles use the same technology as PV panels, and are the same size and shape as a typical asphalt shingle. As with solar panels, solar shingles are paired with inverters and connected to the grid.
Solar panels are slabs of semi-conductor metal. Technically speaking, they are a slab of silicon semi-conductor doped or added with impurities to make it a better conductor. Solar panels could also be made of Gallium Arsenide which is a semi-conductor metal exclusively used in photo-voltaic cells. The silicon slabs are polished and glossed before doping. After processing, for protection, a thin glass layer is embossed on the solar cells slab.
