As a business we have been installing and maintaining pv systems for over 10 yrs.
We design our systems carefully to ensure losses through cable sizes are minimised, we use good panels with closely matched outputs and high efficiency inverters.
Our systems typically yield more than the predicted outputs.
The MCs and RECC approved quoting and prediced output calculations shows that a South facing 4kw System with no shade in South Wales gnerates a 10%plus return on investment.
This can be enhanced further with the addition of a battery back up system with the extra benefit of an emergency power supply in the event of a power cut.

With the drop in component pricing it is very viable for business to reduce its costs with self generation.
Returns of 20% on a roof mounted system are possible.
A 50kw system could generate 2150 cash and save 6000 off the energy bill.
There are also secondary considerations like, budget, brand, Lead Acid or lithium and size etc we will come back to these at the end but lets first look at the first 3.
Is the System Grid Tied or Off Grid.
A grid tied system is less complex and the easiest solution.
Off grid needs more careful planning and a full understanding of the exact power needs.
They are more common than one might think as every boat is an off grid system.
If we are off grid we may not need a 240v ac network.
But if we do we may use a system like the Sunny Island that manages the batteries, creates the grid and can also switch generators on when the batteries are too low.
A Number of our customers have been approached lately by Tele sales companies wanting to change their inverters to a Solar Edge Optimiser System for 4000 and claiming they will get 25% extra generation and you are at risk as your current inverter is out of warranty.
All your panels will need to be removed to fit optimiser's to each panel.
If one of these fails in future you will get a new one on warranty but will have to pay for scaffold etc to replace - you will never get the money back.
The claim of increased generation.
