Authorship

Guides are published under the byline "PlugIn Solar Guru Editorial". Each guide states whether it is research-based or tested, when it was published and when it was last updated.

Sources

  • Product specs cite the page they came from and the date we read it.
  • Manufacturer pages are preferred. Where we cite a retailer or a review instead, the source list says so.
  • Anything no source publishes is shown as "Not verified", never estimated.
  • We quote briefly and link. We do not copy other publishers' guides, photos or parts lists.

Choosing products

Suitability first, then evidence, then the seller's real terms and support, then total cost. Commission is never a ranking factor. A product with no affiliate program can be our top pick, with an unpaid link to the maker.

Safety and claims

  • No kit is described as legal in a state whose law is not yet in effect.
  • "UL 3700 compliant" is never presented as "certified" unless the maker names the testing lab.
  • No plug-in kit is presented as backup power. Kits shut off when the grid does.
  • No system over about 360 W is presented as safe on a shared household circuit.
  • No setup that plugs a battery or generator into a wall outlet to power the house is ever suggested.
  • Savings figures are always shown as estimates from inputs you can change, never as a promise.

Corrections

When we fix a factual error, the guide's update history records the date and what changed. Product pages show their last reviewed date. Catalog changes, such as a product we reclassified as discontinued, are noted on the product page.

Sponsorship and samples

We have no sponsors. If we ever receive a free or discounted product, the page it appears on will say so. Paid placements, if we ever accept any, will be labeled as advertising.
