The short version: Renewable Energy Advisors participates in the Amazon Associates Program and other affiliate programs. When you buy something through links on this site, we may earn a small commission — at no additional cost to you. You pay exactly the same price you would otherwise. These commissions help keep the site running, and they never influence our rankings or recommendations.
What Affiliate Links Are
Many of the product links on this website are "affiliate links." If you click one and go on to make a purchase, the retailer pays us a small referral commission for sending you their way. It works at no cost to you whatsoever — the price you pay is identical whether you use our link or navigate to the product yourself. Think of it as the retailer sharing a slice of their marketing budget with the site that referred you, rather than any charge added to your order.
This is the standard way independent review sites like this one cover their costs — hosting, research time, and the gear we test — without putting up paywalls or cluttering every page with intrusive ads.
📦 Amazon Associates Disclosure
Renewable Energy Advisors is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
As an Amazon Associate, we earn from qualifying purchases.
Amazon and the Amazon logo are trademarks of Amazon.com, Inc. or its affiliates. Product prices and availability are accurate as of the date/time indicated on Amazon and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply to the purchase of the product.
⚖ Our Editorial-Independence Promise
This is the part that matters most, so we want to be crystal clear about it:
Affiliate commissions never influence our rankings, ratings, or recommendations. We choose the products we feature, and the order we rank them in, based purely on what we believe is genuinely best for the reader's specific need — not on which product pays the most.
In practice, that means we will happily name a budget product as our top pick over a pricier one when it's the better choice, even though the cheaper item usually earns us less. We also point out the cons and trade-offs of every product, including ones we recommend. No brand can pay for a better ranking, a more favorable review, or placement on this site. Our opinions are our own.
Why We Use Affiliate Links (Instead of Ads or Fees)
Researching, testing, and writing in-depth product guides takes real time and money. Affiliate commissions let us fund that work in the way we think is fairest to you:
- It's free for you. You never pay a penny more for using our links, and the site stays free to read.
- It keeps the content honest. Because we're paid only when we point you toward something genuinely worth buying, our incentive is aligned with giving you accurate, useful recommendations — not chasing clicks.
- It keeps the site clean. Affiliate links let us avoid the wall of pop-ups, auto-playing videos, and intrusive ads that make so many review sites unpleasant to use.
How We Mark Affiliate Links
We include an affiliate disclosure near the top of every product guide so you always know when a page contains affiliate links — you don't have to dig for it. Our product links (typically "Check Price on Amazon" buttons) are affiliate links. We aim to be upfront and obvious about this on every page, in keeping with the U.S. Federal Trade Commission (FTC) guidelines on disclosing affiliate relationships.
No Guarantee on Prices or Availability
We deliberately don't list specific prices on our product pages, because prices change constantly. Always check the current price and availability directly on the retailer's site (such as Amazon) before buying. We can't guarantee that any product mentioned will be in stock, available, or at any particular price when you visit, and we're not responsible for changes made by the retailer.
Your Choice, Always
Using our affiliate links is entirely optional and always appreciated — it's what keeps this hobby-turned-site going. But you are of course free to search for any product we mention and purchase it however you like. Either way, our recommendations stay exactly the same. We'd rather you buy the right product, period, than feel any pressure to use a particular link.
