Ask the Author

Good morning all!

Today I have run out of productive ideas of things to write about. So I’m doing what any good blogger would do, and am throwing it back to our followers. If you have any pressing questions on building, renovating, or otherwise improving your house please ask away! I will do the next series of blogs answering whatever questions you throw at me.

My one word of caution, keep the questions building related, otherwise you never know what I might say 😛 I have many contacts in the various fields, so I should be able to come up with a somewhat well informed answer!

Thanks guys, looking forward to your questions! (Free advice!! YAY!!!)

  1. I’m interested in putting solar panels up but I live in a century home and I’m not sure if my roof can handle the weight of them. I have 10″ roof boards on the roof deck and the rafters are 2×4 fur with a small plate at the top joins, no other trussing. We installed knee-walls 4′ in from the edges a number of years ago to reverse some bowing. Would solar panels work? Is the return on investment worthwhile? Shingles were replaced 2 years ago..

    1. Hi Val! Thanks for the great question!

      We get very excited when people ask these questions, these are the fun ones to answer. So first I would start by saying there is no blanket answer for whether houses can support solar panels or not. Each house should be evaluated on a case by case basis. What this means is unfortunately each case should be independently viewed by an engineer so he can get all the roof information (pitch, spans, type of roof, orientation, etc).

      The good news is that solar panels don’t add a lot of pounds per square foot. Depending which panel contractor you go with and the panels they use you could expect to see 2-3 pounds per square foot out of a 3×5 panel. So this really isn’t a lot of added weight on a roof. The snow load factor used for calculating trusses is typically 40 lbs/sqft or greater in Winnipeg.

      Now tackling return on investment… This one typically is a bit harder to calculate. This one you really need to consult with a solar contractor. They will determine roof slope, orientation of home, tree cover etc to determine where to install panels so as to maximize their value (For Winnipeg the dream is typically a 7/12 pitch roof with a slight skew from straight south). They should be able to provide feedback on estimated generated electricity. From there it becomes a more simple math game to calculate expected payoff.

      Some things to consider for expected payoffs: 1) If you can afford it now up-front, it will reduce the cost to own down the road. 2) Are you planning to have a battery to store your excess energy, or will you sell to the grid? 3) Currently our electric energy in Manitoba is approximately 65x cleaner per unit of heat generated than gas. 4) What is the value of having some potential power source during an outage?

      Again, thank you Val for the question. I hope this has informed your decision a bit. I know I never directly answered any of your questions, but if you would like us to help you out along the path come contact us and we’ll get you connected to engineers and solar contractors to help make your decision!
