The cost of installing solar in Oregon is very similar to asking how much it costs to buy a car. When you are buying a car, you would have to factor in numerous details, such as make, model, year, condition, and additional options.

The same situation is true with solar. A number of factors combine to determine the cost of your solar installation. How much energy do you use? How much of your energy needs do you want to offset? What is the condition and orientation of your roof? How complex will your solar install be?

Thankfully, our solar experts are ready to help and crunch the numbers for you. Our trained solar engineers can custom design a solar system based on your needs and desires and provide you with a free, no-obligation solar estimate.

Solar panels add weight to your roof, so it’s important to consider the strength of your roof before installing solar.

The good news is that solar actually doesn’t add a ton of weight to your roof. However, it is still vital to ensure your roof can handle the extra weight.

When you work with a professional solar installer, they will conduct a pre-site analysis (PSA) to determine the structural integrity of your roof and advise whether you will need to install additional roof support or not.

Some homeowners and electricians might be tempted to install solar on their own. However, this can be a costly move.

Installing solar on your own means you are no longer eligible for most solar incentives, including federal, state, and local solar incentives. Those are huge savings that could have slashed the cost of your solar install.

Also, if you are not a solar installation professional, it can be easy to make small or major mistakes that could lead to your solar install not working properly. Even worse, it could lead to solar malfunction and potential property damage.

The ideal orientation for installing solar is a south-facing roof. However, you do not need a south-facing roof to install solar or for solar to make financial sense. East-facing and west-facing roofs are also good options for installing solar.

On average, east-facing and west-facing solar panels produce 15% to 20% less electricity than south-facing roofs. However, this can be easily offset by installing a few additional panels to cover that gap.

North-facing roofs are normally unfit for solar installations due to low solar production.
