Photovoltaic power generation employs solar panels comprising a number
of cells containing a photovoltaic material. Light falling on the
panels provides Electricity. This is fed into the Household Electricity
system for use within the house, or
exported to the grid.
Payback and Feed-in-Tariffs
At the moment your energy provider will pay £0.13p per kWh produced,
guaranteed until 2035, this can be used by the household or exported.
If used internally it further saves 12-15p for the kWh it replaces.
This can be achieved using the iBoost immersion controller,
you can purchase it at our new renewables site www.cuberoot-energy.co.uk.
We also offer an installation service.
An average installation costs £5-7000 for a 4kWp system and
produces approximately 3700kWh/year.
If you use 50% of the electricity produced then you will save £220/Year
and receive £530 Feed-in-Tariff. So a total of £750-800/year
tax free. If we assume electricity rises by 3%/year and FITs do also
we get a total payback figure of £20000+ which is an 8% return
on investment i.e. a 9 year payback of initial capital.
We only install the best quality panels and equipment so that you
can have faith that the equipment we install, will work as expected
and, should anything fail within the warranty period, be able to simply
get the items replaced, without any problem. We would normally specify
the likes of Sunpower, Mitsubishi, Sanyo, Schott panels with SMA Sunnyboy

A well fitted PV system will add value to your property as everyone
comes to realise that your house is considerably cheaper to run than
an equivalently sized house without a panel system.
We are increasingly being ask to provide a repair service; many PV
systems have been installed badly or with substandard Chinese equipment.
Leaking roofs, failed inverters are amongst the many problems we are
called out to solve.
