Question 1

What warranties are included?

Accepted Answer

Every National Solar installation includes a 15-year workmanship warranty on our labor, a 25-year manufacturer warranty on solar panels, and a 15-year battery warranty if applicable. System monitoring is included so you can see daily production in real time.

Question 2

How long does the whole process take?

Accepted Answer

Assessment to installation is typically 4 to 6 weeks. The installation itself takes one day. We handle permitting, design, utility interconnection paperwork, and all local inspections, so you do not manage any of it.

Question 3

What if I move before the system is paid off?

Accepted Answer

Solar adds to your home's resale value. Studies show 4 to 6 percent on average. The system transfers to the new owner, and your net metering agreement typically transfers as well. Most customers find solar is a selling advantage, not a complication.

Question 4

Does the Energy Trust rebate apply to my utility?

Accepted Answer

Energy Trust of Oregon incentives are available to customers of PGE and Pacific Power. CEC, Salem Electric, EWEB, and other utilities operate under different programs. We outline what is available for your specific utility during your assessment.

Question 5

What offset percentage should I expect?

Accepted Answer

Most Oregon homes achieve 80 to 100 percent offset, meaning solar covers 80 to 100 percent of your annual kWh usage. The exact figure depends on your roof's orientation, shading, and system size. We give you the specific number upfront before you commit to anything.

Question 6

Will solar eliminate my utility bill completely?

Accepted Answer

Not entirely. Every utility charges a base or facility fee regardless of solar: PGE around $16/mo, Pacific Power around $14/mo, EWEB around $38.50/mo, Salem Electric around $24/mo, and CEC around $31/mo. Solar eliminates the energy charge, the large variable part that escalates every year. Most customers see their total bill drop to the base charge plus a fixed loan payment.

Question 7

Is solar still worth it without the federal tax credit?

Accepted Answer

Yes. Oregon offers some of the most generous state rebates and utility incentives that still make solar a strong investment. We also have fair pricing, strong warranties, and high quality products. Utility companies throughout Oregon continue to raise power rates, and going solar is the best way to protect yourself from future increases.

Question 8

What payment methods are available?

Accepted Answer

We make going solar flexible with multiple options: upfront payment by check, ACH, or credit card, financing plans with low monthly payments, solar leases with no upfront cost, and even Bitcoin for tech-forward homeowners. Our goal is to make clean energy affordable and tailored to every Oregon homeowner.

Question 9

How long will my system last?

Accepted Answer

In the Pacific Northwest you can typically expect modules to last 30 to 50 years or more thanks to our moderate climate. Our Oregon-sourced modules carry a 25 to 30 year warranty, our inverters carry a 25-year warranty, and National Solar adds a 15-year workmanship warranty on every installation.

Question 10

Will solar add to my property tax?

Accepted Answer

No. In Oregon, the value that a PV solar system adds to your home does not affect your property tax, and adding a system does not trigger a reassessment of your property.

Question 11

Do my solar panels need maintenance?

Accepted Answer

A solar system has no moving parts, so little to no maintenance is needed. Keeping panels clean helps production, and Oregon rain usually handles that. If an issue ever arises, we come out and fix it at no cost under our 15-year workmanship warranty.

Question 12

Will solar panels work on my roof?

Accepted Answer

We accommodate nearly any roof, steep or flat, tile, wood, or shingle. Different materials require different mounting methods, which can affect cost. If your roof needs replacement within ten years, we recommend doing that first. If your roof is not ideal, we also offer ground-mounted solutions.
