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 ?

                                                                               2014

                          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

Conclusion

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.

16 x 250 watt Solar Panels Facing South

These customers decided they had enough and put their savings to better use. Solar Panels will make you

more money than interest on your savings account and at the same time reduce your electricity bill !!!

The back of this home faces directly south, there is a tall tree at the bottom of their garden which should only hinder performance in winter. Although shading is not a real issue on this job the customers have decided to have Enphase Micro Inverters instead of a traditional string inverter. These have a 20 year guarantee, they monitor each panels performance seperatly and can give upto 20% more performance in some circumstances.

As well as all those benefits you get monthly email performance reports and emails if any panels / inverters stop working.

Here is the last Enphase Solar Panel System update...

 That's not bad to say we've not had good  weather and were not in Summer either !!!

Customer Solar Install Review

5 Star Review from Customer in Luton

Mr McPhee was so please with his Solar panel installation he wrote us a nice review and recommended us to a relative near Wigan. Rob made us feel welcome while we were installing his system and even made us a nice ice cold jug of juice.

Since his installation was a while ago Rob has reported that he is really happy with the performance of the system. We managed to fit Rob a 4kw system using just 12 panels instead of the usual 16.
