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 mono-crystalline panels are made out of cells from pure silicon. The difference between mono-crystalline and poly-crystalline solar cells is simply that Mono is produced from a single crystal of silicon whilst Poly is produced from a piece of silicon consisting of many crystals.Mono Panels take more time to manufacture and this is reflected on the price.his also means that the Poly Modules absorb slightly less solar energy and produce slightly less electricity, hence the cheaper price. Mono-crystalline solar panels will typically have higher efficiency rates (15-20%), converting energy particularly well in low-light conditions.
