How much electricity can Solar PV
panels produce ?
Therefore a 2 kWp Nu-lok Solar System will produce nearly half of these electrical requirements – as well as reducing the amount of harmful carbon dioxide you create by around 650 kgs!
So with a life span of
around 25 years, a 2kWp Nu-lok Solar System will generate around 37,500
kWh and avoid almost 16,000 tonnes of carbon dioxide emissions being
leaked into the atmosphere – and you thought you couldn’t do anything
about global warming! |

How much
roof area does a Nu-lok Solar PV system need ?
Nu-lok’s specially designed Solar PV panels integrate seamlessly so that your roof looks stunning as well as producing clean and efficient energy. Typically a 1 kWp system will usually require approximately 10 square metres of unshaded roof area, and for the best results, it should face within 90 degrees of south (from south-east through to south-west). If the roof surface is in shadow for parts of the day, the output of the system decreases. |
||||
| What happens on cloudy days ? | ||||
 |
||||
You can still generate electricity, even on a cloudy day.
However the amount of electricity will be reduced. On a light overcast day
here will be enough diffuse light to produce about half the electricity
output that you would get on a bright sunny day. |
||||
| Is solar energy safe ? | ||||
| Solar
panels are completely safe. The glass doesn’t conduct energy so you can’t be
hurt or electrocuted by touching them – even when they are installed and
connected. The installation process is the same as for our normal roof tiles
and the necessary precautions are taken by our trades people when working on
roofs. The final connection and commissioning of your Nu-lok Solar PV system is undertaken by an accredited Electrician to ensure the highest degree of safety and quality service. |
||||
| What happens if there is a power cut? | ||||
|
Nu-lok Solar PV systems are grid connected,
which means that if there is a power cut, your system will automatically be
switched off. This is designed as a safety measure to protect individuals who may be working on restoring the power supply from any electricity that might flow back into the grid from your system. |
||||
| What maintenance and cleaning do the systems need? | ||||
|
Nu-lok Solar PV panels have no moving parts, are
completely silent in operation and require no maintenance. Most of the time
rain will keep the modules clean, however if you have pesky birds in the
area you may need to clean them with a hose from time to time! |
||||
| How much does a solar system cost? | ||||
| Over the last 20 years, the cost of solar PV cells have fallen dramatically
(around 500%) however the cost will obviously depend on what size system you
wish to install. Nu-lok consultants can help design a system for you that fits both your budget and roofing requirements. > Return to top of Page |

Is
government funding available?
Grants are available in most countries..
UK -
Yes – grants are available from the government
to assist with cost of installing a solar system. The £20 million PV Grant
Scheme is administered by the Energy Saving Trust on behalf of the
Department of Trade and Industry. |
||||
| Who can apply for a grant? | ||||
|
UK - Anyone can apply for a grant in the UK – whether you’re an individual homeowner, private business, public or charity organisation, school… anyone! USA - Australasia - similar see below. |
||||
| How do I apply for a grant? | ||||
