Solar & EV Guides for the United States (August 2026)
The federal picture changed twice in 2025. The residential clean energy credit cannot be claimed for expenditures made after 31 December 2025, and the federal new and used EV credits ended for vehicles acquired after 30 September 2025. These guides work from the IRS and DOE wording rather than a vendor’s summary of it, because the difference between "paid" and "installed" is what decides whether a 2026 filer gets anything.
What survives is state-level: credits, rebates and exemptions that each run their own eligibility test, funding cycle and closing date. Several are already exhausted for the year — the guides say so where that is true instead of listing a programme that cannot pay out.
361 guides published. Methodology as everywhere on this site: how we verify.

Electric trucks tow superbly — instant torque, no gear hunting. Then range falls 40-60% and the trip becomes charging logistics. The numbers, and who should.
Can You Charge an EV in the Rain? Snow? A Car Wash?
Yes — connectors are engineered for weather, sealed and de-energized until locked. Why wet charging is safe by design, and the few water rules that do exist.
Can You Charge an EV with a Solar Generator? The Math
Technically yes, usefully rarely: a big power station adds a few miles to a car that drinks tens of kilowatt-hours. Where it helps, and where it is theater.
Can You Jump-Start an EV? And Can It Jump Your Gas Car?
Yes — but it is the little 12-volt battery you are jumping, never the big pack. And using an EV to jump a gas car is where most manuals say no.

The complete EV maintenance schedule fits on a page: tires, cabin filter, brake fluid, coolant intervals, the 12-volt and software. What's gone, what remains.
Why Are Electric Cars So Expensive? And When They Aren't
The battery is the price, the rest is packaging: why EV stickers run high, why the gap narrows every year, and the used-market math that flips the comparison.
Choosing panels & batteries
Panel types and wattages, kits, portable and flexible modules, and how long the hardware lasts.
