INSTALLATION I CASE STUDY
The great-looking panels are designed to integrate seamlessly into roofs and are highly compatible with a wide range of existing roof tiles and slates
Collaborative approach
Before starting work, SunGift discussed the work with LSN Architects, and designed a bespoke system that took into account all of the church’s needs. It specified a 3.95 kWp Solar Century C21e slate system, which it installed on the south-facing roof of the church in order to generate the maximum yield. The great-looking panels are designed to integrate seamlessly into roofs and are highly compatible with a wide range of existing roof tiles and slates.
The system has now been in place for a number of months, and the Reverand Chamberlain is delighted with the energy it is saving the church. “SunGift did a brilliant job,” he said, “and the panels look great. Even more importantly, they are generating a significant amount of electricity and, thanks to a good summer, they’ve generated £213 in Feed-in tariff payments over the past three months.”
These figures are even more positive than the figures that SunGift provided in the initial quote, which estimated £558 in annual Feed-in Tariff payments, £401 in annual savings, and £31 in excess energy sold back to the national grid. The system is expected to save 1.8 tonnes of CO2 per annum, give a return on investment of 5.6 per cent per year, and generate a profit over 20 years of £2,144.
Tile choices
“There are a number of ‘slate’ PV panels that we use in installations,” said Jamie Burnham, SunGift’s design engineer who worked on the project, “but, we specified the Solar Century C21e panels because they are extremely robust and the amount of energy that the panels generate is the best in their class. They were the most appropriate solution for Saint Paul’s Church, and you only have to look at the church’s roof to see how well they blend in.”
The Solar Century C21e panels have a strong pedigree, winning countless awards including the Queen’s Award for Enterprise for Excellence in Innovation, the Ecobuild Best Building Product, and the Sunday Times R&D Award. They’re also extremely durable and have full wind, fire and weather testing, a 25-year power warranty and a 10-year performance guarantee.
