What this site is

This is an independent cost-estimation site for US homeowners who are thinking about home battery backup. It provides calculators, state programme explainers, and comparisons to help a reader work out, in broad terms, what size battery they might need, what it might cost, and how long simple payback might take on stated assumptions.

What this site is not

• This site is **not an installer**. It does not sell, install, or service batteries, and it does not give site-specific quotes.

• This site is **not a utility, a programme administrator, or a manufacturer**. Programme rates, rebates, and eligibility rules come from the official programme pages linked on each state page, and they change.

• This site does **not** give tax advice, legal advice, financial advice, or electrical / installation advice. For those questions, speak to a licensed installer, your utility, and a qualified tax or legal professional.

How the calculators work

Every calculator shows its formula on the page, states its assumptions, and labels every price or programme figure with its source and check date. Calculator results are planning estimates only. They are not quotes, not savings promises, and not recommendations to buy a specific product.

A key 2026 fact used throughout this site: $0 federal credit applies to a homeowner-owned battery installed in 2026, because the 30% Residential Clean Energy Credit (§25D) does not apply to homeowner expenditures made after 31 December 2025. Lease / PPA treatment under §48E is different and depends on the contract price. Re-check this before publishing — tax law and programme rules change.

How this site is funded (summary — see Affiliate Disclosure for the full text)

This site may, once live, earn money from advertising and from affiliate / lead programmes when a reader uses a link to request quotes or buys a product. Any such link will be disclosed beside the link, in plain language, before you click. Commission does not change a calculator's maths, and the site does not accept payment to change a calculator result.

Phase 1 status note (remove at publish time): No affiliate account has been created for this site yet, and no live affiliate link, ID, or discount code exists in these drafts. Do not publish an affiliate link until the programme application is approved and its terms — including Pakistan payout, state tiers, and battery-only eligibility for Solar.com, and the true rate and lead definition for EnergySage via its network — are confirmed in writing.
