What Wren Provides

Commercial Solar PV

From a single rooftop to a multi-site portfolio designed around your consumption, not a standard specification.


A typical 50kWp commercial installation generates 45,000 to 50,000 kWh annually. Payback typically falls between four and eight years. We provide projected figures — cost, output, saving, and payback — before any commitment is made.

What Wren Provides

Residential Solar PV

Solar for your home designed around how you use energy, with or without battery storage.


A typical domestic system of 4kWp generates 3,400

to 3,800 kWh annually. Most households self-consume 50 to 60 percent of what they generate — battery storage pushes that significantly higher.

Battery Storage

Use The Energy You Generate.
When You Need It.

Battery storage removes the biggest limitation of solar-only systems you are no longer tied to using electricity only when the sun is shining.

Self-consumption increases from 30–40 percent toward 70–90 percent with storage added. We install combined solar and battery systems for both commercial and domestic properties, and retrofit storage to existing installations.
