"It appears your solar panels are performing better than your original estimate, which is very good news! Whilst writing please thank your work force for a very competent and professional installation of the solar panels, it took less than a day without any interruptions or problems to ourselves.
We would be more than happy to recommend your company to anyone."  - Mr. Sanders - Newton Abbot, Devon

SOLAR panels have been installed at a city school much to the delight of its eco-conscious pupils.
The Eco Club, at Oreston Community Academy, has been working with the school's site manager for the past year looking at ways to save energy.
Ms Hartley said: "The first morning of being back at school the panels made enough electricity to light a house for about two months" - Oreston Community Academy, Plymouth​
