LIVEWhere to start
Each hub is a full silo: a pillar guide, supporting deep-dives, and the calculator that matches the decision you are trying to make.
Battery Backup
A whole-home battery backup keeps your essential circuits running when the grid goes down, and choosing one means working through real tradeoffs: how many kilowatt-hours you actually need, whether to back up the whole panel or just critical loads, and which battery chemistry fits your budget and climate. The wrong size is an expensive mistake in either direction, so the math matters more than the marketing. This hub covers home battery backup from first principles. You will find sizing guidance, the difference between partial and whole-home systems, transfer switch and interlock basics, LiFePO4 versus other chemistries, and honest comparisons of the systems worth considering. The goal is a setup that holds through a real outage, not a spec sheet that looks good in a showroom.
Open hub →Power Stations
Portable power stations have replaced gas generators for a growing number of homes, and for good reason: they run indoors without fumes, recharge from solar, and need almost no maintenance. The catch is that capacity, output, and expandability vary enormously, and a unit that runs a CPAP all night may stall the moment you plug in a refrigerator. This hub breaks down portable solar generators by what they can genuinely power and who they suit. Expect capacity-tier explainers, use-case guides for RVs, medical equipment, job sites, and outages, real-world run-time math, and brand-versus-brand comparisons. Every recommendation is built on published specifications and documented owner experience, so you can match a unit to your actual load instead of a headline wattage.
Open hub →DIY & Wiring
Building your own off-grid system is the most rewarding and the most unforgiving path into solar. Get the component matching right and you have a setup that outlasts anything off the shelf. Get the wire gauge or fuse sizing wrong and you have a fire risk. The difference is knowing the numbers, and the numbers are not hard once they are explained clearly. This hub is the technical core of the site: wiring diagrams, charge controller and inverter selection, busbar and fuse sizing, panel-to-battery matching, and build guides for vans, cabins, sheds, and ground mounts. The content assumes you want to understand the system, not just copy a parts list. Treat every guide as a starting point and confirm your final design with a licensed electrician before you energize anything.

Building your own off-grid system is the most rewarding and the most unforgiving path into solar. Get the component matching right and you have a setup that outlasts anything off the shelf. Get the wire gauge or fuse sizing wrong and you have a fire risk. The difference is knowing the numbers, and the numbers are not hard once they are explained clearly. What you pay for solar, and what you get back, depends heavily on where you live. Net metering rules, the federal tax credit, state and utility rebates, and local permitting requirements vary from one jurisdiction to the next, and they change often enough that last year's advice can quietly cost you money. This hub tracks the policy side of going solar in plain language. You will find state-by-state net metering breakdowns, current federal tax credit guidance, permitting and interconnection basics, and payback explanations you can act on. Policy details shift, so use these guides to understand the landscape, then confirm the specifics with your utility and a local installer before you commit.
