Why Texas's climate shapes your battery choice
Texas's subtropical/continental (heat + storms) climate makes battery backup essential, not optional. Average Texas grid outage during major storms is 24-72 hours. A 13.5 kWh battery (Tesla Powerwall 3, LG ESS) covers roughly 1.5 days of essential loads (refrigerator, lights, well pump, modem).
Lithium iron phosphate (LFP) batteries are preferred for Texas — thermal runaway risk in high-heat conditions favors LFP over NMC chemistry. Top picks: Tesla Powerwall 3 (LFP), EG4 Powerpro, Franklin aPower 2. At Texas's $0.14/kWh utility rate, batteries also unlock TOU arbitrage outside of outage events, shortening payback to 7-9 years vs 12+ years in lower-rate states.
Texas Solar at a Glance
