Essays that stay useful after the campaign ends
Eight evergreen notes we keep updating: certificates versus state add-ons, inverter architecture, the battery “when”, orientation, quote comparison, export limits, warranties, and maintenance.

How to compare two solar quotes fairly
Line up kilowatts, models, mounting, inclusions, and STC treatment. A cheaper net price with thinner paper is a different job, not a saving.

What maintenance does rooftop solar need?
Look from the ground, keep gutters clear, and hire a professional if soiling is heavy or the inverter alarms. Do not walk a live tiled roof.

Solar export limits in Australia
A DNSP export cap is a connection condition, not a broken inverter. Ask what the quote assumed before you treat a feed-in tariff as a plan.

What warranties matter on panels and inverters
Product, performance, inverter, battery, and workmanship are different documents. Ask who you call in year eight — not only what the brochure promises.

STC vs state rebates: what actually changes your quote
Federal STCs, shrinking deeming, and state add-ons are different machines. A feed-in tariff is a fourth thing. Here is how to read a quote without mixing them.
