Solar panels and how they work

Envirotekenergy provide a range of solar panels (PV modules), ranging from budget to the latest monocrystalline and hybrid models.

PV (Photovoltaic) is a combination of two words: ‘photo’ meaning light and ‘voltaic’ meaning volt, a unit of electrical force. Photovoltaic technology is the term used to describe the hardware that converts solar energy generated from solar panels into usable power ELECTRICITY.

A solar panel is a collection of small solar cells or photovoltaic cells which spread over a large area in a grid like pattern. These cells can work together to collect sunlight during the daylight hours and convert it into electricity. The more light that hits the cell, the more electricity it produces.

solar panels feed in tariffSolar panel cells or photovoltaic cells are often silicon based pieces of material that absorb the sun’s light many of these cells are combined in solar panels. Solar energy excites the electrons in the solar cell and electricity is produced, this electricity is in the form of direct current or DC. DC however is not useable for most common purposes, so next DC power is transformed through an inverter to alternate current AC.

Solar panels can work on a variety of roofs, they don’t weigh much at all so they won’t damage your roof and they need very little maintenance. The government have relaxed the planning laws so unless you live in a listed building or conservation area you generally won’t need planning permission.

 

Earn with the Feed-In Tariff (FIT)

The Feed-In Tariff (FIT) was introduced in April 2010 as a financial incentive to encourage the generation of electricity using renewable sources. To qualify for FITs, the installer and products must both be certified under the Microgeneration Certification Scheme (MCS).

You will benefit from FITs in following ways:

Generation tariff: You will be paid a set rate by your energy supplier for every single unit (or KWh) of electricity you generate via your installation.

Export tariff: On top of the Generation tariff, you will be paid a further set rate for every unit of electricity, which is currently set at 4.77p/kWh, you don’t use that you export back to the grid known as the Export tariff.

Energy savings: By generating your own free energy, you will be saving on your electricity bill as you don’t need to buy as much from your energy supplier.

 

Feed in-Tariff rates

Total installed capacity (kW)
Generation tariff with eligibility date on or after 1 April 2014 and before 1 July 2014
Lower tariff (if EPC requirement not met) with eligibility date on or after 1 April 2014 and before 1 July 2014
<4kW (new build and retrofit)14.38p/kWh6.61p/kWh
>4-10kW13.03p/kWh6.61p/kWh
>10-50kW12.13p/kWh6.61p/kWh
stand-alone6.61p/kWh6.61p/kWh

 

With the current Feed-in Tariff rates you could save up to £750* per year. The table below is a guide to show what you could save depending on when you had your instalation.

System size
Savings per year
Carbon dioxide per year
Registered on and from 1st April 20144kWp£7501.8 tonnes
Registered up until 31st March 20144kWp£7701.8 tonnes

It is impossible to predict the performance of solar PV systems due to the difference of amount of solar radiation (sunlight) in different locations and time of year. The above estimates are average savings taken from Energy Savings Trust and is based on the standard MCS procedure. You should not consider these figures as completely accurate.
