What we have learned about solar in Ghana.
Sizing, tariffs, batteries, maintenance and payback — written by the team that supplies and installs the systems, for the questions that decide whether solar pays for itself here.

The hidden trap of “cheap” solar: why low-quality panels destroy your ECG bill savings
Cheap solar is the fastest way to lose the savings it was bought for. Heat, grid spikes, battery chemistry and a warranty that never travels decide whether the system pays for itself.
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.
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.
