promiseenergy.com
Link authority for promiseenergy.com (registrable domain: promiseenergy.com) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Web-graph authority (0-100)
Domain scores measure promiseenergy.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 promiseenergy.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.

The exact savings depend on your location, energy usage patterns, available roof space, and current utility rates. With California's high electricity costs and abundant sunshine, most businesses see a return on investment within 3-5 years."}},{"@type":"Question","name":"What incentives are available for commercial solar in California?","acceptedAnswer":{"@type":"Answer","text":"California offers multiple incentives including the federal Investment Tax Credit (30% of system cost), accelerated depreciation (MACRS), the Self-Generation Incentive Program (SGIP) for battery storage, and various utility rebates. Net Energy Metering (NEM) allows you to sell excess power back to the grid. We help maximize all available incentives to reduce your upfront costs by up to 50%."}},{"@type":"Question","name":"How long does commercial solar installation take?","acceptedAnswer":{"@type":"Answer","text":"Commercial solar installations typically take 2-8 weeks from start to finish, depending on system size and complexity. This includes 1-2 weeks for permitting, 1-4 weeks for installation, and 1-2 weeks for inspection and interconnection. We work efficiently to minimize disruption to your business operations."}},{"@type":"Question","name":"What maintenance is required for commercial solar systems?","acceptedAnswer":{"@type":"Answer","text":"Solar systems require minimal maintenance - primarily annual inspections and occasional cleaning. We offer comprehensive maintenance packages that include remote monitoring, preventive maintenance, cleaning services, and rapid response to any issues. Most systems come with 25-year warranties on panels and 10-year warranties on inverters."}},{"@type":"Question","name":"Can solar panels power my entire commercial building?","acceptedAnswer":{"@type":"Answer","text":"Yes, with adequate roof space or ground area, solar can provide 100% of your building's electricity needs. We design systems to optimize your available space and can combine solar with battery storage to provide power during peak demand periods or outages. Many of our clients achieve net-zero energy consumption."}},{"@type":"Question","name":"What is the ROI for commercial solar in California?","acceptedAnswer":{"@type":"Answer","text":"Commercial solar in California typically provides 15-30% annual ROI with payback periods of 3-5 years. This includes savings from reduced electricity bills, protection from rate increases, tax incentives, and increased property value. Over 25 years, most systems provide 3-5x return on investment."}},{"@type":"Question","name":"Do you offer financing for commercial solar projects?","acceptedAnswer":{"@type":"Answer","text":"Yes, we offer multiple financing options including cash purchase, loans, leases, and Power Purchase Agreements (PPAs). Many options require $0 down and provide immediate positive cash flow. We work with leading financial partners to structure deals that match your budget and goals."}},{"@type":"Question","name":"How does battery storage benefit commercial properties?","acceptedAnswer":{"@type":"Answer","text":"Battery storage provides multiple benefits: reducing peak demand charges (often 30-50% of your bill), providing backup power during outages, storing excess solar energy for use when rates are highest, and participating in utility demand response programs for additional revenue. The SGIP rebate can cover up to 50% of battery costs."}}]}]}JSON-LD block (3,752 bytes)

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 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 promiseenergy.com and domain-level for promiseenergy.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 promiseenergy.com (including its subdomains), ranked by the linker's PageRank. The table shows the top 12; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.

Top backlinks in the host graph
The HOST graph connects exact hostnames, so subdomains count separately. This table shows the highest-authority hosts linking to promiseenergy.com specifically, ranked by the linker's PageRank. The table shows the top 9; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
