"A warning to anyone considering using Sunlight Solar Energy of Bend Oregon. I had a small system installed on my home in Colorado TWO years ago; a location they no longer service. They installed the system on my roof which was 18 years old, and not in the correct condition ( of which I was unaware) to accept panels as the roof was not well ventilated because of short cuts in the building process. The damage was obvious to every single roofing contractor that came to look at it. I could not detect the damage because the pitch of the roof is extreme. After calling several other reputable solar companies, they all made clear it is an industry standard to not install a roof older than 10 years and all companies advise homeowners to have the roof checked first before installing panels. Never once did Ryan Campbell the installer speak to me about the condition of the roof, which had many years worth of damage. His goal was to get the panels up, take my money and disappear. And disappear they did. Ryan's number disconnected, and the Colorado website page for Sunlight has one digit off so that you can't reach anyone that way either. I did however find a way to contact Paul, the president of the company, and ask for help in getting the panels de-installed and reinstalled after the roof gets replaced (on my dime) given they did not discuss the roof with me prior to install. He first agreed to help me by finding a solar company to take the panels down ( a cherry picker is required because it it so steep $$$$$$) and then refused to help at all a few days later. As someone who runs a small business, I am disgusted. I would never treat a customer this way. As a homeowner, and a professor of environmental sociology who professes the value of solar, I am enraged. This company is awful. Steer as far clear of them as you can. There are other companies deserving of your business."

Earthquake Retrofitting questions, answered by experts

First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises. In addition, you’ll need to provide the retrofit team access to areas of the house that will need to be worked on, meaning you’ll need to relocate personal items, clear clutter, and make pathways for the crew. Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.

Depending on where you live, your insurance company may require you to have a seismic shut-off valve. It depends on local regulations along with the specific provider. If it’s not a requirement, many providers will offer a discount if you install an earthquake valve, which can save you 5% or more. Contact your provider to learn about potential savings for your plan.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Hearing or feeling vibrations in your house can be unsettling, but there are a few possible causes for a vibrating noise in your wall or floor. Light bulbs and fixtures, circuit breakers, loose pipes, or faulty wiring could all cause vibrations. If you’re not sure what’s causing the vibrations, you can call a contractor to assess your home and narrow down the cause.
