Talk to Modern Electric
Had a call with Cave Mode from Mosaic that changed how I think about battery storage. The insight that stuck: how to actually model degradation curves properly. Cave has the kind of perspective that only comes from doing the work - not just studying it or writing about it. These conversations are where I learn the most. What I appreciate is the honesty. No spin, no pitch. Just real talk about what works and what doesn't.

What the Numbers Look Like
At $0.14/kWh, the average Texas electric bill runs about $144/month. Solar typically offsets 80-90% of that, saving roughly $122/month or $1,468/year. Over a 25-year panel lifespan, that's about $36,700 in savings. Texas gets about 234 peak sun hours per year, which puts it in the top tier nationally for solar production. And with the 30% federal tax credit still available through 2032, the math works for most homeowners.

Why Texas Solar Pays Off Faster
Texas sits in one of the best solar zones in the country. With an average of 234 peak sun hours per year, systems in Texas produce more energy per panel than most states. That's why the payback period here tends to be shorter than the national average.
The federal solar investment tax credit (ITC) covers 30% of your total installation cost. For a typical $18,000 system, that's $5,400 back on your taxes. Some Texas utilities also offer buyback programs where you get credit for excess energy your panels send to the grid. Between the tax credit, lower monthly bills, and potential buyback earnings, most Texas homeowners see a full return on their solar investment within 8-12 years.
