Editorial Policy

Clear standards, dated claims, disclosed commerce.

We prefer a useful caveat over a confident but stale answer.

Research approach

We use public specifications, utility pages, state program pages, IRS guidance, DSIRE, manufacturer documentation, buyer questions, and quote-pattern analysis. When a claim depends on a program date, we say the date.

How we evaluate brands

We judge batteries on fit, not prestige. A high-output flagship can still be the wrong recommendation for a small backup need, a tight budget, or a home whose existing solar hardware points elsewhere. When a brand is hard to source, thinly supported in a market, or leaning on marketing over specs, we say so directly.

Corrections

Incentives and product specs change. If a factual issue is reported, we update the page instead of letting stale guidance linger.

Safety and tax limits

Electrical installation belongs with licensed professionals. Tax treatment belongs with qualified tax advisors. We help buyers ask better questions.

What independence means here

Independence does not mean having no commercial interest. It means those interests do not dictate the verdict. If the cheaper battery, the smaller system, or waiting a year is the better call for a buyer, that should be the recommendation, even when a more expensive path would pay us more.
