Renewable Energy Systems

Photovoltaics (PV)

Converts sunlight directly into electricity. The direct conversion of sunlight into electricity falls into three categories

• RPV, Residential PV for the domestic sector (1-5kWp), typically a roof array
• BIPV, Building integrated PV for the commercial and industrial sector (10-250kWp) which can be fully integrated into the external cladding system
• CPV, Centralised PV for the utility generation and distribution sector (100kWp-5MWp) which for instance, can run in parallel with the local grid

Combined Heat and Power (CHP)

Direct heating of the air by the waste heat from power generators which can supply hot water and cooling for a variety of applications.

This type of renewable energy system can replace several other necessary items such as standby generators, boilers, air handling units and control systems. Single unit power outputs range from 50kWe to 1.5MWe and 100kW to 3MW of thermal energy. Units can be multi-installed to meet total energy requirements. Carbon dioxide levels can be reduced by up to 50% and primary energy consumption by 40%.

Biomass

The creation of energy from waste and other materials.

Biomass continues to play an important role in the development of renewable energy systems. The availability of Biomass and its careful management is an important factor in determining the feasibility of this source of renewable energy. Where enormous quantities of agricultural waste, such as that derived from sugar cane and rice are available the chances of success are very high. It can also operate from forestry or wood processing residues.

Geo-Thermal

A practical way of using the earth's energy to provide heating and cooling for commercial premises and retail outlets.

This system meets the heating and cooling requirements of a variety of operations by recovering and upgrading the low grade energy stored in the ground surrounding the building. The system will typically reduce carbon dioxide emission by 60% and being buried in the ground it is both invisible and silent. There is no need for any separate boiler, flue, cooling tower, water treatment or associated plant rooms. Total building resource content is greatly reduced, allowing for more of the commercial aspects of the business.
