The last thing you want is to be surprised at trial with the damaging testimony. Therefore, it is usually wise to take that witness' deposition so that you will know in advance what that witness will say. A deposition does not take place in court. Instead, it usually takes place at an attorney's office. The attorney will ask the witness, or deponent, a series of questions about facts related to the lawsuit. The rules allow some latitude in the areas that can be inquired into.
Life Expectancy of Solar Panels. With care and cleaning, solar panels can last up to 40 years. Certain issues can make them fail, but in general a solar panel is a long-lasting device and a good investment. Basics. Solar panels have no moving parts, so as long as they remain sealed they can work. The typical manufacturer's warranty on a solar panel is 25 to 30 years, but panels can last up to 40 years with care and attention.
A roof top solar system has no moving parts, so it has a long expected lifetime exceeding 25 years (used in this example). 1  However inverters (which convert the panel DC current into AC) have an expected lifetime of 10 to 15 years. In our example we add the cost of a replacement inverter to the system after 12 years.
