A home battery has exactly three jobs — export arbitrage, peak shaving, outage backup — and your tariff decides which pay. The test that replaces the pitch.

For camp power, outage essentials and gasless apartments, genuinely yes; as 'free energy' or whole-home backup, marketing. The real wins, and who should skip.

With the 30% federal credit gone, whether solar pays now turns on four local numbers: your electricity rate, your sun, your export policy, your incentives.

America's best sun meets modest 15¢ rates and net billing that pays APS exports 6.171¢ for ten years: Arizona wins on volume, not policy generosity.

California pairs the mainland's highest rates (33.25¢) with the harshest export policy, NEM 3.0. Solar still wins here — but only battery-shaped.

Colorado is the Northeast's mirror image: excellent high-altitude sun against 16.16¢ power. Net metering carries the case; the Xcel rebate is gone.

Florida still has what most states lost - full retail net metering at the big utilities, plus 100% property and sales tax exemptions. The nickname holds.

Illinois Shines still pays some of the Midwest's best solar money — but net metering shrank to the supply half of the bill for interconnections from Jan 2025.

New England's weakest sun meets America's second-highest power prices, a 20-year production adder and a state tax credit. The SMART 3.0 math, plainly.

New Jersey stacks full retail net metering, 23¢ power AND cash per megawatt-hour: SREC-II pays $85/MWh locked 15 years for July registrations, $77 after.

New York pairs near-30¢ power with 1:1 net metering locked 20 years, a state credit and NY-Sun rebates: the Northeast's strongest yes, minus a CBC charge.

North Carolina's answer has a countdown: Duke's favorable Bridge Rate closes to new applicants December 31, 2026. The 15¢ math, and what replaces it.

Pennsylvania offers no state credit and no rebate, and still pencils — because it kept full 1:1 retail net metering, what every other state is dismantling.

Texas has huge sun, middling rates (16.44¢ in May 2026), no statewide net metering and a 100% property tax exemption. It hinges on your retail provider.

Yes — solar grazing is a working industry: sheep are its stars, cattle need taller steel, crops share light by design. How farms stack two harvests.

A modern fridge sips 1-1.5 kWh a day, one panel's output, making it solar's easiest customer. The outage math and the compressor-start footnote.

A 1,500W space heater devours a panel's whole day in an hour — resistive heat is solar's worst customer. The heat-pump escape hatch, and winter's cruel timing.

A well pump's daily energy is tiny — its starting surge is the tyrant. Why grid-tied solar ignores it, why off-grid designs around it, and the soft-start fix.

Central AC draws 3-5 kW and doubles a summer bill — and peaks exactly when panels produce. Grid-tied solar handles it; the panel math, the off-grid asterisk.

Most states have solar access laws stopping HOAs from banning panels — but 'reasonable restrictions' on placement are the live fight. Your rights and theirs.
