LED's (Light Emitting Diode) are fast replacing traditional bulbs such as fluorescent and incandescents as a highly efficient light source.
Typically a 6 watt LED down-lighter will replace a 50 watt halogen down- lighter therefore saving you 90%. They will give you like for like brightness and should last a life time.
LEDs have been around for many years, but it is only recently that they have been developed for a wide range of lighting applications.
They are small and can be exceptionally bright, as well as costing comparatively little. Add in an incredibly long life cycle and it's easy to see why they are rapidly replacing many other traditional light sources Many people will be familiar with solar-powered LED garden lights but the range of applications is growing fast.
LED's are now used for room lighting, security lighting and flood lighting, as well as commercial applications such as traffic lights, car brake lights and advertising boards.
A large portion of the energy your solar panels produce will be exported back to the grid.
In standby mode 90% of the electricity you generate could be exported.
It is assumed that you export 50% of what you generate and this is what you are paid for by your energy supplier at around 5 pence per unit regardless of how much energy is actually exported.
Your energy supplier will then sell it back to you at a much higher rate (typically 12 pence per unit) when you require more energy than you are generating.
It makes sense therefore to harness this energy, prevent it from going back to the grid and use it yourself.
Battery storage enables you store your excess generation for you to use later when your consumption is higher than your generation.
