Below we have answered some of the most frequently asked questions we receive regarding renewable energy. If you have any further questions not covered here, please do not hesitate to get in touch by contacting us.
Q: What is the Microgeneration Certification Scheme?
A: The Microgeneration Certification Scheme, MCS, is a registration scheme sponsored by the Department of Energy & Climate Change within which installers that meet the accreditation requirements of the scheme can install products accredited within the scheme for their customers. As a result of an accredited installer using an accredited product the installation is eligible for either the Feed in Tariff or the Renewable Heat Incentive.
Q: What rate of VAT do I pay on renewable energy installations?
A: Renewable energy products installed, not simply supplied, are rated at a reduced VAT level of five percent. If the product is supplied only the rate is twenty percent.
Heat Pump Questions
Q: Do Heat Pumps only work in new houses?
A: It is true that the heat emitters need to be upgraded when fitting heat pumps to older houses to ensure the correct level of heat is put into a room. High temperature heat pumps are also available which give the same heat as an oil or gas boiler which means that radiators will not always have to be changed.
Q: How can you take heat from the air when it is cold outside?
A: Heat Pumps extract energy from the air or ground not heat, they convert this low grade energy into the heat that we all recognise to heat our homes and hot water.
Q: What maintenance will a heat pump need?
A: To be compliant with the Microgeneration Certification Scheme standards an annual service should be completed on a heat pump to ensure that it maintains maximum efficiency.
Q: Will my garden freeze?
A: This would only happen on a poorly designed system, all of the design and survey work we complete is focussed with the intention of achieving a heat pump installation whereby the ground loops stay above zero degrees during their operation.
Solar PV Questions
Q: Do we get enough sun for Photovoltaic systems?
A: Whilst direct bright sunlight produces the highest levels of electricity Solar Photovoltaic panels also work in daylight . The calculation of the amount of energy your system could produce is completed in a government defined standard manner and takes account of the change in the strength of the sun over the year.
Q: Is my roof suitable?
A: Any building with a structurally strong roof, or a wall facing south, southeast, or southwest, is suitable for installation, providing there are no obvious obstructions to the path of light. However, even a roof that is shaded for part of the day is still suitable, but will have a decreased output.
Q: Will we get electricity in a power cuts?
A: Unfortunately no you would not, the inverter on the Solar Photovoltaic system needs to see the mains electricity coming into your property to match itself to the grid. If the grid goes off so will the Solar Photovoltaic system.
