Plain-language guides from our engineering desk: policy changes, technology comparisons and sizing methods — written for buyers, importers and installers.
Efficiency is watts per square metre, not energy. Why the temperature coefficient and degradation rate decide your yield — and the four numbers to compare first.
CE and base UL listings are not grid approvals. How the four rulebooks differ, where the 3.68 kW line falls, and the five documents to check before you ship.
From August 2026, plug-in solar kits up to 800W are a recognised product category in Great Britain. What the new connection route means for households — and the checklist importers cannot skip.
Module-level electronics or a central box on the wall? Cost, safety, shading and monitoring compared — with a simple rule of thumb for choosing.
Why LiFePO4 became the default for home storage, and how depth of discharge, temperature and BMS quality decide real-world lifespan.
A load-audit-first, five-step sizing method with a worked example — plus the surge-current trap that sinks most first designs.
Eight checks before you order a plug-in balcony kit: mounting, plug standards, certification, weight, cabling, monitoring, expansion and support.
