2. 10 Good
Reasons
Why Choose
Solar PV
For a number of years now alternative energy has been a hot topic of
discussion by politicians and consumers, and there is now no escaping the fact
that without everyone making real steps to reduce their carbon footprint we
will drain the planets precious resources and cause potentially serious
environmental damage.
As a part of our carbon footprint reduction we need to cut down on the
amount of non renewable energy we use, as well as learning to become more
efficient in our energy consumption. The need to change to renewable and self
sufficient energy generation is further compounded by the ever increasing cost
of using conventional non renewable energy, with electricity prices set to
begin increasing again in 2017.
The Solar PV industry is now very established with millions of homes now
using this technology to produce power. As a result this technology is now
much more affordable, and coupled with the government backed incentives
that are still available, it is not only of benefit and applicable to every home, it
is something most consumers can afford to invest in.
The battery storage and smart home systems that are now available have
really expanded the potential of domestic solar PV systems, as it means homes
can be powered day and night from solar energy, as well as enabling your
home to function off grid in the event of a powercut.
The goverment incentives will be reducing over time, and electricity prices are
set to increase, so there has never been a better time start saving money on
your electricity bills, and to make your first steps towards self sufficiency and
environmental responsibility.

How Solar
PV Works
Solar PV (Photovoltaic) panels are the most popular of all renewable energy installs, due to the
established nature of the technology, making it very cost effective and highly affordable to even the
average environmentally conscious consumer.
It can generate power 365 days a year, and has the ability to power your home day and night when
combined with battery storage. With government financial incentives still in place, it is an obvious first
step towards self sufficiency and cost savings in a world of continued energy price increases.
Solar PV systems produce free electricity from the sun's rays, through a
process called photovoltaic streaming, where photons ejected from the sun
are converted into electrons that can be used to power your home. A system
requires solar panels and an inverter to convert the energy from the solar
panels into electricity that can be used in the home.

5. Aesthetic
LG 300W Mono Neon 2 Black
In the pursuit of greater aesthetics black panels have become very popular
with many clients. LG has now taken the all black to the next level with the
Neon 2 Black panel, which is perhaps the best looking panel on the market.

importance of aesthetics as well as high performance in construction.
Marking another step forward for LG’s range of modules, already know to have
excellent build quality, performance, reliability and appearance. When
installed in arrays, the Neon 2 Black offers a more uniform appearance,
enabling PV modules to integrate into new and existing buildings without
necessarily making the array the focal point of the building.
This module continues the trend from LG of state of the art, high performing,
well made, good looking products.
Optimise
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.
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.

Whilst previously separate monitoring systems have been required, all of our
suggested systems and inverters come with their own effective monitoring portals that
can be accessed via computer or mobile phone app. No separate monitoring device is
required, just available onsite wifi.
Part of the selection criteria for the systems
we recommend is their proven, relaible and
intuative and easy to use monitoring
systems. Solar Edge has the ultimate
monitoring portal, with even panel level
monitoring capabilities, and both SMA and
Solis have very user friendly systems.

10. Free Hot
Water
Solar iBoost Immersion Heater Controller
The Solar iBoost automatically converts energy generated by PV panels into
hot water by diverting excess solar power to the immersion heater before it’s
exported to the national grid.
Simple to use and maintenance free, the iBoost is self contained and can save
you hundreds of pounds off your heating bills, and can provide all your
domestic hot water needs for most of the year.
An immersion controller is a very inexpensive way to maximise your solar self
consumption, and provides a simple answer to summertime domestic hot
water heating for solid fuel heated homes.
Immersion ControlAn immersion controller is a very cost effective addition to your solar pv system to help
you maximise your self consumption and bill savings. It diverts any unused power you
generate to your immersion element rather than to the grid. A great companion to any
boiler system, and it is capable of providing all your hot water for a significant portion
of the year.
