Choosing between string and microinverters for a split roof
South-east at the front, north-west at the back. The decision came down to one specific bit of hardware.
Energy Stack / Solar
Solar
Solar is the layer most people start with. Hardware choices have settled down a bit, so the interesting questions are about the survey, the inverter type, the rate you get for what you send back, and how the system pairs with anything else you might add later.
Guides
Panels
What a panel spec sheet actually tells you, and which numbers should matter when comparing quotes.
Inverters
Three choices, broadly. Once you sketch out the roof, the right answer is usually obvious.
Mounting
What the brackets actually attach to, and what should worry you when an installer suggests shortcuts.
Install
A short page on a deeply unglamorous part of the install that has a habit of failing first.
Output
A reader sent us their first year of generation data. We graphed it against the original estimate.
Self-use
Timers, hot water, dishwashers, EV charging. The small jobs that shift the self-consumption number.

A 2.8 kWp system was the sensible number in 2019. It is not now, and the reasoning is not just about price.

A reader's generation data. The story is more interesting than the brochure suggested.
