The weight of a PV system is spread across many square feet of your roof. The effect is negligable. PV installations are not hazards when they are installed by established, reputable companies.
Don't listen to the other person. We have it on our roof and are so happy. Almost no energy (electricity) costs and we drive an electric vehicle. Saving about $300 - 400 a month. The only way to go.
My brother just retired as a fire captain and there a absolute no problems. They can still open the roof on the North side or any other roof slope that doesn't have the panels.
Only on very old houses there could be weight problem and should be checked; and if the roof tiles are old then redo the roof before upgrading to solar. Many roofers can already put in the hardware for solar or even do the whole job.
Roof Weight: The added weight of the solar panels to the roof is negligible. Residential roofs are designed to handle dead loads (structure) and live loads (snow, rain, people) a minimum of 40+ lbs per square foot, the weight of the solar panels are about 3 lbs per square foot.
Fire Access: Most all areas have fire codes that may require 2-3 feet around the solar panel area for the firemen to access the roof and cut holes if necessary. Solar panel arrays usually cover about 1/2 to 2/3 of the roof, and the firemen can also cut holes in the north side of the roof if necessary.
Insurance Premiums: The most important item is to check the added premium for the increased value of your home with the addition of solar panels. Some areas, California for example, forbid an increase in premiums for the addition of solar panels. USAA uses a service called ‘Xactware’ to estimate the risk and replacement costs. “Xactimate is the industry's leading claims estimating solution” for insurance companies. www.xactware.com/ This system uses the number of panels to estimate the added value, i.e. risk, of the solar panels.
My system has 22 panels, Xactimate estimated a dwelling increase of $35,000, however this increase automatically ripples through other coverages such as ‘Other Structures’ and 'Personal Properties' for a total increase of $64,750 and a premium increase of $165.74.
I thought this was particularly high as it is about 3.5 times the cost of my solar system of about $18,5000, and solar system costs are predicted to continue to decrease for several years to come. I asked to talk with a USAA representative to discuss this further. This was followed by a phone conservation and an on-line ‘Chat’ with a very helpful and knowledgeable USAA representative. After explaining the entire situation, we negotiated a total increased value of $18,500 and a premium increase of $47.37 per year or $3.95 per month.
The concern is that most people may not ask about the valuation and premium increase, which will show up much later in their annual mortgage escrow adjustment and will be brushed off as normal increases in insurance and/or taxes. Be informed!
SunnySideUp, I understand that you have concerns about a proposed increase to your homeowners insurance premiums due to the installation of solar panels. I'll share your post with our insurance team. An insurance expert will conduct a follow-up with you during regular business hours. ~DC
Thanks for posting in our Member Community SunnySideUp. Solar panels are pretty cool, and something I've been interested in myself. I can certainly go over the quote options with you. It could be that the dwelling amount itself was reevaluated, solar panels or not. Let's have a look, and I appreciate the opportunity.

Curious what the outcome was for those who have installed a solar system with USAA. What was the impact on your homeowners coverage cost?
I, too, am considering installing solar. I am wondering if I will need to switch away from USAA to make the savings of installing solar worthwhile...
