Solar PV Installation Options

“Tailor made solar pv systems to suit your specific needs and requirements, and desires.  You can select what you want from our extensive solar pv installation options and we will install the perfect solar panel system for you.”



We are happy to install any system of your choice if you have a particular brand, or look of panel, you specifically want to have as part of your system. However to make things easier for you, we have selected what we consider the best panels available, for a variety of budgets and system needs. We have made this selection based upon:

  • Quality (the feedback from our fitters as to the robustness of the panels, as well as the manufacturers reputations and warranty lengths.)
  • Value (the highest ratios of performance related to price)
  • Aesthetics (how the panel look on your home is a major consideration for many clients and we make sure our panels are as discrete and stylish looking as possible)

SolarEdge P300 Solar Panel Optimiser
SolarEdge power optimisers maximise energy from each panel, through constant tracking of Maximum Power Point per panel. Optimal efficiency is achieved by automatically maintaining a fixed string voltage, and performance can be monitored via the SolarEdge monitoring portal.

solar edge solar panel optimizer solar pv installation panel choice
Module mismatch occurs when modules in an array do not exhibit fully identical electrical properties or when exposed to different environmental conditions. Module mismatch leads to a different maximum power point (MPP) per module.



Sources of module-mismatch:

· Partial shading & uneven soiling causes different irradiance levels on different modules
· Temperature gradient – heat convection across the solar array causes different temperature levels on different modules
· Manufacturing tolerance & uneven aging rate cause the modules to perform at different MPP parameters
String systems lower the string’s output to the level of the lowest performing module.

SolarEdge power optimizers perform MPP tracking for each module individually and therefore extract the maximum energy from each module, regardless of other modules in the string.

  • increase energy yields from your system by up to 25%
  • increase the output from any make of panel
  • maximise array design flexibility
  • 25 year warranty


The inverter for your system is a critical component, and as with the solar panels we are happy to install any suitably sized inverter you request. However to make your life easier the following is our recommended selection of inverters, chosen for reliability, value, warranty, and quality.
