Going Solar Frequently Asked Questions

How long will my system last?

System longevity depends on climate conditions and the quality of modules installed, but typically in the PNW you can expect your modules to last 30 to 50 years or more thanks to our moderate climate. Our OR-sourced modules are designed for the PNW and come with a warranty ranging from 25 to 30 years.

Our inverters, which convert DC power to AC, also have a 25-year warranty and should last the lifespan of your solar modules. In addition to the manufacturer’s warranties, National Solar stands behind our work with a 10-year workmanship warranty for all our solar installations.

What is the environmental impact of solar?

Going solar is a great way to impact the environment in a positive way. Although OR state is a leading renewable energy producer, about 25% of our energy still comes from non-renewable sources, which produce hundreds of tons of pollutants and greenhouse gases that harm both human health and the environment we live in. Investing in solar helps to reduce your fossil fuel consumption for 30 to 50 years or more thanks to the longevity of solar systems in the PNW, and the greenhouse gas offset across a solar system’s lifespan is equivalent to planting an entire forest of trees.

Do my solar panels need maintenance?

A solar system has no moving parts, so there should be no maintenance necessary. Keeping your panels clean, however, will affect production. Rain is usually sufficient to keep panels clean throughout the year for solar owners in OR, but it is a good practice to check your panels annually and clean if needed.

If ever there is an issue that arises with your system, we will come out and fix it at no cost to you under our 5-year workmanship warranty.

Will solar panels work on my roof?

We do our best to accommodate any roof, steep or flat, tile, wood, or shingle. All roofs can be installed with solar, but your roof type may impact the cost. Different roofing materials require different installation methods and this can add time to your install to ensure that your system is properly mounted. If your roof will need to be replaced during the next ten years we recommend that it be replaced before scheduling your solar installation. If your roof is not ideal for a solar installation, we also offer raised, ground-mounted solutions as well.

Will solar panels harm my roof?

No. In fact, they will help serve to protect your roof from weathering and keep your house cooler in the summer and warmer in the winter. We use a wind and weather-resistant, hurricane-rated mounting system that will not corrode, warp, or break your roof and will not cause leaks.

Will solar affect my homes value?

Yes, and in a good way!  According to a study by the US Department of Energy, any home improvement that lowers electricity bills by $1000 annually will increase a home’s value by about $20,000

Will solar add to my property tax?

No. In Oregon State, the additional value that PV solar systems add to your home does not affect your property tax. Neither will adding a solar system trigger a reassessment of your property.

"I am so happy with this company! I contacted another solar company several years ago and had nothing but problems with them. I was hesitant to try again. I found National Solar and had a very rewarding experience with them. Pat, my project manager explained the entire process, made it easy to understand and answered all of my questions. The installation crew was friendly, efficient and knowledgeable. They even suggested adding a generator plug. My installation was quick and I now have solar. THANK YOU. Pat and his team are GREAT!"

"Of the six companies I contacted initially, National Solar was the one that sounded and acted most competently. The initial visit involved a thorough explanation of the system and its function, and we were pleased to sign the contract. The contractor and installation crew were prompt, competent and helpful. Last week 23 panels were installed, and yesterday the utility came out to replace the meter. Within 10-15 minutes, the system was up and functioning. This morning I was informed that one of the microinverters was not communicating, and a repair ticket was filed by the contractor to fix it properly. Overall, we are Most pleased and feel we were well-treated. I can recommend National Solar without reservation."

"Friendly Staff. Competitive pricing. Professional installation. After being cold-called by another company I reached out to National Solar for a competing bid. The sales consultant was friendly and knowledgeable. Everything he promised was delivered in a timely manner. The process was smooth and now I am generating energy on my roof and couldn't be happier."
