Current Scores

Web-graph authority (0-100)

Domain scores measure nationalsolarusa.com as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname nationalsolarusa.com. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What warranties are included?","acceptedAnswer":{"@type":"Answer","text":"Every National Solar installation includes a 10-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."}},{"@type":"Question","name":"How long does the whole process take?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"What if I move before the system is paid off?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"Does the Energy Trust rebate apply to my utility?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"What offset percentage should I expect?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"Will solar eliminate my utility bill completely?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"Is solar still worth it without the federal tax credit?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"What payment methods are available?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"How long will my system last?","acceptedAnswer":{"@type":"Answer","text":"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 10-year workmanship warranty on every installation."}},{"@type":"Question","name":"Will solar add to my property tax?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"Do my solar panels need maintenance?","acceptedAnswer":{"@type":"Answer","text":"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 10-year workmanship warranty."}},{"@type":"Question","name":"Will solar panels work on my roof?","acceptedAnswer":{"@type":"Answer","text":"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."}}]}

Web-Graph History

Authority over time

Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.

A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.

Backlink Data

Backlink counts

Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for nationalsolarusa.com and domain-level for nationalsolarusa.com with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.

Top backlinks in the domain graph

Common Crawl publishes two link graphs. The DOMAIN graph connects whole domains: every link from any page of one domain to any page of another. This table shows the highest-authority domains linking to nationalsolarusa.com (including its subdomains), ranked by the linker's PageRank. The table shows the top 21; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.

The HOST graph connects exact hostnames, so subdomains count separately. This table shows the highest-authority hosts linking to nationalsolarusa.com specifically, ranked by the linker's PageRank.
