What we have learned, written down.
Practical guidance for projects in Ghana: specification, sequencing and the decisions that are expensive to reverse. Written by the people supplying and installing the systems, not by a marketing department.
Choosing finishes for Accra humidity and harmattan dust
Ghanaian interiors fail in two seasons for two different reasons: moisture that never quite leaves, and dust that arrives all at once. The finish that looks right on a sample board is not always the one that still looks right in March.
How to think about solar cost against current ECG tariffs
Payback is not a property of a panel. It is a property of your tariff band, your daytime load, and a PURC schedule that changes. Here is how to use the published April 2026 rates without treating a round number as a guarantee.
Sizing battery storage for real outages
Two numbers decide whether a battery system meets your expectations, and most quotations only make one of them obvious. Confusing kilowatts with kilowatt-hours is the commonest reason a correctly built installation still disappoints.
Cameras that help when something actually happens
Resolution is the specification everyone compares and the one that least often decides whether footage turns out to be useful. Placement, light and retention matter more, and all three are settled before anything is bought.
Porcelain, LVP or engineered wood: choosing a floor that lasts
A floor is chosen from a sample held in the hand and judged years later underfoot. The properties that decide how it ages — substrate, moisture and traffic — are the ones a sample cannot show you.
Choosing between SPC, WPC and fluted wall panels
The three panel families look similar on a sample board and behave very differently on a wall. What actually separates them is the core, and the core decides where each one belongs.
Why solar output falls, and what actually restores it
Production rarely collapses. It drifts down slowly enough that nobody notices until a bill looks wrong, and by then the cause is months old. Three things account for most of the loss, and only one of them is dirt.
Sizing a solar system: what your bill actually tells you
Most sizing conversations start with panel count. They should start with when you use power, because that single fact decides whether you need a large array, a large battery, or neither.
Wired or retrofit: choosing a smart home approach
The decision is made by your building programme, not by the technology. If the walls are open you have one set of options; if they are closed you have another, and both can produce a good result.
Waterproofing: the work you never see and always pay for
Waterproofing is the cheapest element of a wet room to install and by a wide margin the most expensive to correct. Nearly every failure we are called to inspect traces back to a detail, not a product.
