Not all roofs perform the same when it comes to solar. Orientation, pitch, shading, size, condition, and roof material all affect how much electricity panels generate and how safe the installation is. Here's what to check before installing.

Integrated solar panels sit flush within your roof structure rather than on brackets above it, giving a cleaner look and replacing some roofing materials. Here's how they work, how they compare to standard panels, installation, and cost.

Solar panels only generate when the sun's out. A Battery Energy Storage System (BESS) stores the excess they produce, then releases it when generation drops or demand peaks. Here's what BESS is and how it supports a solar setup.

While business tends to think in quarters, commercial solar panels can last 25 years or more. If you're weighing up an installation and want to know what kind of lifespan to expect, this guide walks through the factors that affect it.

The payback period is when your electricity savings match what the system cost to install, typically 4 to 6 years for commercial solar. Here's how it's calculated and what affects it: usage, electricity rates, and whether you add battery storage.

Of the 1.85 million buildings with solar across the UK, most panels are fixed using a hook and rail system, or installed as integrated panels within the roof itself. Here's how these methods work across different roof types.
