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.
The second class of solar panels are both the polycrystalline solar panels and the monocrystalline solar panels and these together make up around 95% of solar panels sold in America. Most of these solar panels have 25 year warranties and I have seen many solar panels of these types that are more than 30 years old still working quite well. I don't think there is likely to be any difference between monocrystalline and polycrystalline solar panels when it comes to how long they last.
