Why we install Aiko Solar
We chose Aiko because their ABC panels squeeze the most energy out of every square metre of roof — which matters enormously on UK homes where roof space is limited. The 30-year warranty and Tier-1 Bloomberg NEF status means our customers' investment is protected for decades.
