Study shows efficiency of solar power.

Summary: Research into solar panels and technology has revealed they could provide up to 60 per cent of a home's hot water - if properly installed.

Research into solar panels and technology has revealed they could provide up to 60 per cent of a home's hot water.

Under existing guidelines, around 39 per cent of household needs are catered for by solar energy.

But a survey conducted by the Energy Saving Trust (EST) found that the actual efficiency of the systems varied hugely, with the worst performing installations provided just 9 per cent of heating needs.

They determined that with careful and clever installation the system's performance could be vastly boosted.

The report found that central to the performance of the system was proper, high quality insulation. Correct installation, particularly of the hot water tanks, was vital.

The findings may help make solar systems, which cost several thousand pounds, more financially attractive in the long run.

Jaryn Bradford, senior technical manager for the EST, said: "Our study strongly affirms that getting your insulation sorted and thorough research of your needs in advance should always be the first priorities when planning to install a solar water-heating system.

"No matter how good the collector on your roof might be, if your home isn't efficient, if your tank and pipes aren't lagged, and if the system isn't properly sized for your hot water demand, then you're not going to see as good a result as you could."
