The NEM 2.0 Battery Play
The upgrade your grandfathered customers don't know they need.
Every customer you interconnected before April 2023 in California is sitting on a rate structure that no longer exists for new solar. Adding a battery lets them use more of what they generate — and battery-only retrofits keep their NEM 2.0 grandfathering.
Feed it the battery_candidate cohort from Play 01.
Before you start: the 30% federal residential credit (25D) expired for expenditures after 31 Dec 2025. Do not build a campaign around it. The prompt below blocks it.
Stage 1 — Build the campaign
You are a direct-response copywriter who works with residential solar installers.
Write a re-engagement email sequence to my existing customers who are on
grandfathered net metering and do not yet have battery storage.
### MY SITUATION
Company: [name]
Service area: [region]
Years in business: [n]
Battery products I install: [e.g. Powerwall 3, Enphase IQ, Franklin]
Segment size: [count from Play 01]
Install years covered: [e.g. 2016-2022]
### THE OFFER
[what you actually want them to do — free battery assessment, fixed-price
retrofit quote, a call, etc.]
### FACTS YOU MUST GET RIGHT
- The federal residential clean energy credit (25D) EXPIRED for expenditures
after 2025-12-31. Do NOT reference it, imply it, or write copy that assumes a
30% credit. This is the fastest way to make me look uninformed to my own
customers.
- Third-party-owned paths (lease/PPA) sit under a different section of the tax
code with a different timeline. Do not assert anything specific about them.
- In California, adding battery storage to an existing NEM 2.0 system does NOT
by itself cost the customer their grandfathering — the rules were written to
encourage it. What CAN put grandfathering at risk is expanding generating
capacity, or a change that alters the interconnection agreement's capacity
designation. The safe framing is: a battery-only retrofit preserves NEM 2.0,
and any capacity increase should be confirmed with the utility first.
- Existing arrays can almost always be retrofitted regardless of original brand,
using AC coupling.
- If my state is not California, do not assert net-metering specifics. Write the
copy so I can drop in my own state's rule, and mark clearly where.
### WRITE
A 4-email sequence. For each: subject line, preview text, body.
1. The re-introduction. We installed your system in {{install_year}}. Here is
something that changed that affects you. No pitch.
2. The mechanism. What a battery actually does for someone on their rate
structure, in plain language. Where their money currently goes.
3. Objection handling. Lead with "will I lose my grandfathering" because it is
the first thing they will ask. Then cost, then disruption.
4. The direct ask, with a clean way to decline.
### RULES
- Write to a homeowner, not an engineer. No jargon without a plain-English gloss.
- No fabricated savings numbers. Where a figure belongs, use a bracketed
placeholder I fill in — I have their actual production data.
- No fake urgency. Their grandfathering runs 20 years; pretending it expires
next month is a lie they can check.
- Merge tokens only: {{first_name}}, {{install_year}}, {{system_kw}}. Never
invent customer details.
- Bodies as single-line text with \n where line breaks go.
### OUTPUT
CSV: segment | step | delay_days | subject | preview | body | merge_fields | notes
Then a short note on which claims I must verify for my own utility before
sending.Stage 2 — Handle the replies
You are helping a solar installer respond to replies from a battery retrofit
campaign to existing customers.
Write short, honest responses to each of these, in my voice — direct, no
pressure, treating them as someone I already did work for:
- "Will I lose my NEM 2.0 if I add a battery?"
- "How much does it cost?"
- "Isn't there a tax credit for this?" <- the 25D residential credit expired
after 2025-12-31. The answer must be straight about that, then move to what
actually does affect their economics. Do not soften it into a maybe.
- "I'm thinking about moving in a few years."
- "My system already covers my usage, why would I need this?"
- "Can I add more panels at the same time?" <- flag the grandfathering risk
of increasing generating capacity; confirm with the utility first.
- "Not interested." <- one line, gracious, no rebuttal, offer the annual
production report instead so the relationship survives.
### RULES
- Never oversell. These people already bought from me once.
- If the honest answer is "a battery does not make sense for you", write that
answer. It is worth more than the sale.What to do with it
Run 04 — The Warranty Window against the same customers afterward if their inverters are aging. A battery conversation and an inverter conversation land very differently, and the same household can be right for both at different times.
Want this run for you instead of by you? That is the job.
