Choosing your technology
Choose a solar photovoltaic (PV), wind turbine (WIND) or solar thermal (ST) system with help from TLCP and financial assistance from Low Carbon Buildings: Phase 2.
A single system can incorporate up to three renewable energy technologies.
|generates electricity using solar energy||powers lights, computers, appliances, etc.|
|generates electricity using the wind energy||powers lights, computers, appliances, etc.
|creates heat using solar energy||‘collectors’ harness heat energy for hot water|
|works in direct and diffuse sunlight||n/a||is a viable technology for the UK|
|works best in consistent wind supply||n/a||n/a||average wind resource of 6m/s or more is required|
|can be affected by shade or obstructions||PV / ST suffers reduced energy gain in shade
for best results with WIND avoid tall trees, buildings, etc.
|can be roof mounted||PV / ST is commonly roof mounted
wind turbines can be mounted on buildings in some circumstances
|can be building integrated||many BIPV products are available eg PV glazing, PV tiles, PV cladding|
|can be free standing||a variety of mounting and pitches are possible for PV / WIND / ST|
|works well at south facing sites||n/a||maximises energy gain from the sun at southerly orientation|
|reduces fuel bills||PV / WIND reduces electricity purchased from energy provider
ST reduces quantity of gas or electricity purchased from energy provider
|connects to grid for consistent supply and electricity export||excess energy generated can export to grid at agreed tariff|
|connects to existing and new
hot water systems
|simple plumbing principles apply for ST|
|is completely carbon-free||no fossil fuels required to run|
|does not require a lot of maintenance||PV / ST is very low-maintenance
regular maintenance is required for windturbines
|are safe even in high winds|| safety mechanisms are incorporated in WIND turbines
PV / ST include quality mounting systems
