SOLAR PV

Solar PV converts sunlight directly into electricity using a layered cell formation of highly refined silicone. When subjected to light the cells an electric field is created. To achieve this PV requires only requires daylight, not sunlight. Almost zero maintenance costs makes this a very attractive investment with many warranties available up to 25 years. Typically a small domestic system would save around 1.2 tonnes of CO2 per year, 30 tonnes over a systems lifetime.

There are a vast array of panels available on the market, from traditional looking solar panels, to solar cells designed to look like roof tiles, even transparent cells that can be used to roof glass conservatories.

One of the many benefits for selecting a solar PV installation is that it can easily be installed on almost any building and can also be retrofitted to any existing system.

SOLAR THERMAL

Solar water heating can provide approximately 40-60% of a buildings’ hot water requirements. The system comprises of three primary components, solar panels or collectors, a heat transfer system and a hot water cylinder.
The solar panels harvest the heat from the suns radiation, through the heat transfer system the collected heat is used to raise the water temperature. The heated water is collected and this in turn is stored in the cylinder for use as required.

Installation of a solar water heating system is relatively simple, generally comes with up to 10 year warranties and requires minimal maintenance. These factors make this an attractive investment to any business or household.

HEAT PUMPS (Ground Heat)

A heat pump system moves heat from one location, referred to as the  source, to another location. the 'sink' or 'heat sink', using mechanical equipment.

It is fact that a few metres below the surface of the earth, the ground remains at a constant temperature of between 10-15°, throughout the UK. This fact allows us to use technology to transfer this latent heat to domestic or commercial properties through the utilisation of ground source heat pumps. Heat is simply taken from below the ground and is transported though the heating system to the buildings interior. In more sophisticated systems this can be reversed to cool down buildings in the summer.

Two methods are available for this, the “slinky”, which is installed horizontally and referred to as a ground collector, or the bore hole variety, referred to as a bore hole. While a small amount of power is required to “drive” the system, the return is generally 3:1.

  Advantages of this system:

•   Low operating and maintenance costs. Fewer components and more reliable.
•   Will provide domestic water heater free, or at substantial cost reduction.
•   More durable when compared to HVAC systems, anticipated life span of 50 years.
•   Low noise and greatly reduced emissions.

BIOMASS

Biomass is a low carbon renewable fuel. When compared with fossil fuels, carbon emissions can be reduced by up to 90% when biomass installations are managed by experienced and qualified engineers.

Biomass is quickly increasing in its popularity and its role in today’s fuel market is becoming ever more significant.

The range of boilers available is growing and improving in efficiency continually, from hand fed to large fully automated systems, and are available to suit projects with heat load requirements from as little as 2.5Kw for use in Eco Homes to 360Kw for schools, large offices, public buildings and industrial facilities. Multi mega watt biomass power stations are also being built throughout the country.

E-Tech Group will advise on the selection of the most appropriate system for our clients project, provide a full design service and carry out the complete installation using our experienced engineering teams.  

WIND POWER

Modern wind turbines use the winds’ lift forces to turn aerodynamic blades which turn a motor, creating electricity. This form of renewable energy supply has a massive potential in the UK and one of the exciting advantages is that wind power is directly proportional to the cube of the wind speed.

This roughly translated means that with a relatively minor increase in wind speed, a large increase in potential output is achieved.

E-Tech Group can install small turbines supplying energy for battery charging systems, to much larger wind farms supplying this energy into the national grid system.

Government incentives for installation and capital costs are widely available and advice can be given on these at the survey stage. The inclusion of wind power to any new or existing properties can form an integral part of reducing the carbon footprint of a business as well as providing long term cost savings.
