Secure your home with CCTV

The dark and cold are coming !!!

Make sure your home is secure ready for winter with a cctv system

With the nights drawing in it makes a thief's life easier providing more cover, they can tell if your in just by looking for any lighting inside your home. 

So what can you do ? 

Firstly you should check any existing light fittings making sure the bulbs are ok and the fitting is operational. If not then think about your key areas that a burglar would use to creep around you home and get them illuminated.

After this you should really consider a discrete CCTV system. These systems are so advanced now you can set them to email you a picture of a perpetrator the moment they are picked up by a camera and you can view the cameras with your phone, tablet or pc.

CCTV acts as a great early warning system and deterrent after they see you've got one they will probably go elsewhere.  

See our CCTV page and make sure to click on the DVR specs to see great detail how these modern CCTV systems could transform your homes security.

Solar Panels - South Facing Vs East / West

Solar Panels - Which Way should they Face ?

Case Study: 

We fitted these 2 systems last year 
read on to see which one works best and see the data for yourself.

4 Kw Facing South


2 Kw Facing West                 (4 Kw Split system)               2 Kw Facing East

The photo's above show 2 different 4kw solar pv systems, the top one has all 4kw facing South and the bottom shows a system which has 2kw facing East & 2kw facing West.

Both of the above systems have 16 x Eging 250 watt Polycrystalline panels connected to 16 x Enphase micro inverters. One house faces East/West and the other faces North/South both with
a very similar roof angle and both located in Mansfield Nottinghamshire within 3 miles of each other if that.

The Theory:

South Facing

This system will produce a larger amount of power through the middle of the day.

East / West Facing

This system will switch on earlier produce a lesser amount of energy but over a longer spread of time switching off later in the day than a South facing system.

So which one works the best ?

                          Jan      Feb      Mar      Apr      May     Jun      Jul      Aug          Total
4Kw South       103      156       325       366       416       440      549      418           2,773

4Kw Split           65      125       285       344       429      462       544      409           2,234


In this case the South facing system has outperformed the split system by 539 Units of electricity.
Upon close examination of the figures it can be noted that the split system has a very similar output and in May it even outperformed the South facing system by 13 Units.

Even if your home is not facing South you can still benefit from the installation of Solar Pv.

If the roof of your property is facing east/west then don’t worry it does not mean you cannot have solar panels. The system will still produce a good amount of electricity.
