Roof tile solar cells are developed for plastic plain tile covering system. The solar roof tile consists of a unit of six individual tiles, which covers an area of 107cm X 30 cm. It is linked to the neighbouring plain tiles ie, a hook construction and requires no additional mechanical fastening. The solar modules lay flat on the rooftop, interlocking smoothly with standard roof tiles for a smooth look. They are compatible with most shapes and sizes of roof tiles used in new residential construction, with one module replacing five standard concrete tiles. This solar BIPV roof tiles have shingle designs interlock with roof tiles and shingles to provide an aesthetic, seamless look.

Roof Top air conditioners is a self-contained, air-conditioning unit that comprises mixing box, filter, direct-expansion cooler coil, air-cooled condensing unit, direct-fired air heater battery and supply fan with motor, drive and switch gear. This unit is weather-proofed, prewired and factory tested. It only requires electrical connections and a gas or oil feed, after erection on the roof, to operate. Such units are available in a range of capacities from 5 to 100 kW of refrigeration and from 17 to 150kW of heating. The filters provided as standard are generally washable polyurethane foam or oil-impregnated glass fibre, but electrical filters can also be obtained. The advantage of roof-top units are that they are simple and cheap, no boiler plant is needed, duct distribution systems can be reduced to a minimum, multiple units can be used to provide multiple zone control and they are ideal for single-storey commercial buildings.
