Energy, Explained Honestly
Short, plain-language guides — the same explanations we give at your kitchen table.

Education first — that’s the GreenTag way. Start here, then bring your questions to a real conversation.
Arizona utilities charge more for power at peak hours (typically late afternoon and evening). Solar covers your daytime use; a battery shifts your stored solar into those expensive hours. Understanding your rate plan is step one of any honest system design.
Start from what must stay on in an outage — fridge, Wi-Fi, medical equipment, some cooling — and for how long. Whole-home backup is comfort; critical-loads backup is value. The right answer comes from your panel schedule, not a sales script.
Haboob winds and summer storms test every rooftop attachment. Annual torque checks, sealed penetrations, and secured wiring are cheap insurance — and exactly what our maintenance visits verify before every storm season.
No, solar does not work "for free" — it works on math. No, more panels are not always better — right-sized beats over-sized. And no, your roof is not too old for solar — but if it needs replacing within the next few years, it makes sense to reroof first. If panels are already up, we handle the detach & reset (removing and reinstalling them) so the roofer can work underneath.
Charging overnight on an off-peak plan typically costs a fraction of public fast-charging — often the equivalent of paying well under $2 per "gallon." A Level 2 charger pays for its install in convenience alone; paired with solar, the math gets even better.
Every home is different, and generic advice only goes so far. A GreenTag consultation is a conversation, not a pitch — bring these topics, your bills, and your skepticism.
