You’ve read all about solar panels and now you’re gung-ho to get them installed on your home. Well, slow down there, sunny. Safety is a priority on any project and solar technology requires a wide knowledge of specialized technology. To see if you are qualified, Solar Today magazine has put together a list of 10 questions you should be able to answer before you start (on page 66) :

  1. Are you familiar with volts, amps and watts?
  2. Can you find the tangent of 22.6 degrees?
  3. Can you determine the maximum open-circuit voltage of a PV module at your home?
  4. What size lag screw will resist 350 pounds of up force in fir lumber?
  5. What do the symbols THWN, USE and RHW mean?
  6. Are you a skilled do-it-yourselfer with a wide assortment of hand and power tools?
  7. Have you bent and installed EMT?
  8. Do you have a torque screwdriver?
  9. How do you seal roof penetrations that will last for 40 years?
  10. Can commonly available DC-rated circuit breakers be used at 600 volts?

It’s strongly recommended to hire a contractor who specializes in solar technology if you cannot answer these questions easily.
