New World Energy – Renewables
The System
Our system provides electricity, space heating and hot water requirements to be met providing a zero carbon footprint for the building. This is achieved by using a combination of established renewable technologies – hybrid solar panels (known as solar-thermal panels) and a ground source heat pump.
How does it work?
1. A roof mounted array of solar thermal panels generates electricity exceeds the dwellings demands.
2. The excess energy is stored within the battery bank with excess energy sold back to the grid or used to preheat the ground within the properties boundary, through a series of buried straight and slinky pipework. Because earth has a large thermal capacity but poor thermal conductivity the heat is in effect stored there ready to be used by the ground source system, along with the naturally occurring heat.
3. The ground source heat pump extracts the heat which can be a higher temperature than the earth would usually be. The Coefficient of Performance (COP) of the pump is therefore higher than normal.
4. Throughout the year the solar thermal array continues to drip feed energy into the battery bank which provides electricity to run the dwelling and the heat pump.
5. The battery bank is designed to hold enough energy for up to 3 months without any external energy input.
The Benefits
1. Market leading environmental credentials
2. Value of system belongs to dwellings owner therefore adds value.
3. Zero running costs and Income generator for owner adds value.
4. RHI Payment pays for investment.
5. Neat tidy and clean
According to: www.energysavingtrust.org.uk
The average domestic solar PV system is 4kWp and costs around £6,200 (+ VAT at 5 per cent).
Installing a typical ground source system costs around c£18,000 (+ VAT at 5 per cent).
Each technology has a different tariff; for solar is 21.09p, ground source is 20.89p and biomass 6.88p.
