Mrs Potter will now benefit from, not only two brand new condensing boilers under the Green Deal, but also a fantastic Solar Photovoltaic (PV) array on her roof. This has increased the EPC rating from an E 45 to a D 60. What’s more, is that she was able to get £270 Green Deal cashback on her boilers and thermostatic controls by having a Green Deal Assessment.
Due to her energy efficiency rating reaching a ‘D’, because of the boiler replacements and the Solar PV, she is now able to claim the full FiT rate.
New Condensing Boiler and Thermostatic Control System under the Green Deal
- 2 x new condensing boilers with efficiency ratings of over 90%
- Replacing old, none-condensing boilers with 74% efficiency
- Saving £513 per year – £256.50 per boiler
- Thermostatic radiator valves on all radiators
- Saving £91 per year
More about the Solar PV system and the Feed-in-Tariff:
Because of the ‘D’ rated energy efficiency rating of the property the higher rate of 14.35 comes into play. This means that she will be paid 14.35p for each of the estimated 2836 kWh of electrical generation each year, totalling around £410.
Mrs Potter will then be paid for 50% of that generation as ‘export’, being paid 4.67p of (2836 kWh x 0.5) around £67
The further savings will be the electricity used straight from the panels, lets say 50%, as that means she doesn’t have to buy it from the grid. Therefore (2386 kWh x 0.5) x her current price of electricity, lets say 15p. Around £212
Solar PV summary:
- A beautiful array of Solar PV panels
- 3.84 kW capacity
- Generating an estimated 2836 kWh per year
- F.i.T generation means that earns £407 per year
- 50% export back to the grid means a further £66.22 per year
- 50% used means further savings of £212 per year
Mr Chaggar from Ealing, London not only benefits from a well insulated home but he and his family can utilise renewable heating and electricity both produced on site. As the home is fairly new and has been insulated throughout, which means it requires less amount of energy to provide for the needs of the people residing there.
Mr Chagger used TheGreenAge’s partner Complete Plumbing Clean Energy (CPCE) to carry out the work on the heating and solar PV system. CPCE provide a high level of precision and engineering expertise to deliver projects of this type.
By combining electricity produced on site means that some of this energy is then used to power the compressor on the air source heat pump, there is little use for gas central in this instance.
The installation includes the following:
- Mitsubishi Ecodan air source heat pump
- Underfloor heating throughout the property
- 1kWp Bisol solar PV system
- High efficiency hot water tank
Grants and Subsidy benefits to the customer
- Renewable Heat Incentive (RHI) payments for producing renewable hot water on the air source heat pump;
- Feed-in Tariff payments for the electricity produced and exported by the solar PV system
While there is an upfront cost component to paying for the solar PV and the air source heat pump, because of the Government subsidies available, the cost should be recovered within the first 7-8 years on both systems. While there isn’t Green Deal Finance help on the air source heat pump (due to the RHI), customer can get help from this funding for a solar PV system.
To claim the RHI, and potentially get some funding from Green Deal Finance for solar PV, the customer has to have a Green Deal Assessment (carried out here by us, TheGreenAge) and have an MCS certificate produced by the installer (produced by CPCE).
