About WattSage

Our mission

The home energy storage market is one of the fastest-growing consumer technology categories of the decade — and also one of the most opaque. Manufacturer marketing pages dominate search results. Installer margins vary by 40% or more between quotes for identical equipment. State and federal incentive programs change quarterly, and most installers don't proactively file the paperwork. Homeowners are flying blind, and that's the problem WattSage exists to solve.

Our mission is simple: give every homeowner the information they need to make confident, cost-effective decisions about home energy storage — without sales pressure, without manufacturer bias, and without the technical jargon that keeps most people from even starting the conversation. We believe the next five years will see home batteries move from a luxury item to a household essential, and we want to be the trusted editorial voice that helps homeowners navigate that transition.

What we cover

WattSage focuses on three core topic areas, each anchored by a deep-dive pillar guide:

• Home battery buying — Independent comparisons of the five mainstream U.S. residential batteries (Tesla, Enphase, FranklinWH, LG, SolarEdge). See our best home batteries of 2026 guide.
• Vehicle-to-Home (V2H) — The most under-covered home energy story of the decade. Which EVs support bidirectional charging, which chargers work, what it costs. See our V2H explainer.
• Cost, incentives, and ROI — Clear-eyed math on what batteries actually cost, how the 30% federal credit works, and which state programs you're probably missing. See our 2026 cost breakdown.

We deliberately don't cover residential solar (panels, inverters, racking) in depth — that's a saturated content category with strong existing editorial sites. Our focus is the storage side of the equation, which is where the genuinely useful independent content gap exists.

Editorial standards

Every WattSage article is held to the following standards:

1. No manufacturer funding. We do not accept paid placements, sponsored reviews, or "gifted" equipment. Manufacturers do not see our reviews before publication.
2. Independent product evaluation. Our product comparisons are based on manufacturer spec sheets, warranty documents, third-party testing (where available), and aggregated reader survey data. We do not run our own laboratory testing — we leave that to NREL, EPRI, and other accredited labs.
3. Regular updates. Every article is reviewed and re-dated at least quarterly. Pricing data is refreshed monthly. Anything older than 12 months carries a visible "needs review" notice until it's updated.
4. Source transparency. Where we cite data (pricing trends, incentive program details, vehicle specifications), we link to the original source. Where data is our own (reader surveys, installer interviews), we describe the methodology.
5. Corrections policy. If we get something wrong, we fix it transparently. Every article has a visible "Last updated" date, and material corrections are noted in a changelog at the bottom of the article.

How we're funded

WattSage is funded by two revenue streams, both of which we disclose transparently:

• Display advertising. We run ads through AdSense at launch, with plans to graduate to Mediavine once we hit 50,000 monthly sessions. We do not accept direct ad deals from battery manufacturers or installers — only programmatic ads through reputable networks.
• Affiliate commissions. When a reader purchases products through Amazon affiliate links on our site, we earn a commission on qualifying purchases. These commissions do not affect our editorial coverage — we recommend specific products based on their merits, not on commission rate. Our affiliate links cover a broad range of products across multiple brands, giving us no incentive to push one over another.

We do not sell reader email addresses. We do not accept paid product placements. We do not allow manufacturers to review or approve our content before publication. If you ever see content on WattSage that you believe violates these standards, please contact us — we take editorial integrity seriously.

Who we are

WattSage was founded in 2025 by a small team of energy journalists, residential solar industry veterans, and data analysts. Our editorial team has a combined 40+ years of experience covering the U.S. energy industry, including prior stints at Greentech Media, PV Magazine, and the Rocky Mountain Institute. We do not disclose individual author identities to avoid being approached by manufacturers with off-record briefings, but our editorial standards and corrections policy are publicly accountable.

If you have a question, suggestion, correction, or partnership inquiry, please reach out through our contact page. We read every message and respond to substantive inquiries within 5 business days.

Editorial calendar for 2026
