Domestic Photovoltaic Solar Systems

The logical choice to reduce your energy bills and still enjoy a great investment. Not only is generating your own energy good for the environment, it is also good for your pocket! With ever-rising fuel bills, energy efficiency and reducing your carbon footprint have never been more rewarding. See our domestic case studies and see why current FIT rates combined with reduced system costs are making solar power more attractive than ever. If this is not reason enough, concerns over the future of our energy supplies, escalating bills and an uncertain future make this an insurance policy that you can’t afford to be without.

Is My Property Suitable ?

There are many contributing factors to a systems’ effectiveness, such as location, angle, shading etc. By far the best way to check is to have one of our experienced surveyors visit you personally and prepare a no obligation report and quotation. Not only will this highlight your system options, it will also show the estimated generation that you can expect from your system based on accurate details prior to installation – instead of averages and ‘best case’ figures.

What Will My System Look Like ?

Your New Green, Efficient, Profitable System.


We’ve installed hundreds of systems of every size and will tailor a tried and tested solution with the minimum impact to your property – and you.
Installations can take as little as one day and you’ll notice immediate changes to your bills.

Solar Installations

Empower Energy Ltd can take care of every part of the solar PV panel installation for you right from the initial survey to helping with the forms to your electricity supplier.

The whole process is very straightforward, causes minimal disruption, and is often completed right through from scaffold erection to being signed off in less than a week.

We can organise the scaffolding, our specialised roofers fit the supports and our team of highly experienced fitters and electricians fit the panels and do the internal electrical work.

You can rest assured of a courteous, prompt and professional service. We are also fully insured so you can feel safe in the knowledge that in the unlikely event of an accident we are completely liable for and damage.

The Devil Is Really In The Detail

We use PV sol EXPERT advanced planning software to get the very best from your installation before we even touch a single cable. This helps us take into account every variable that could impact on the performance of your system both now, and in the future. It helps us with problems such as:

  • Define the extent to which roof objects could cause shading.
  • Calculate shade frequency distribution for each individual module with millimetre precision to optimise panel placement.
  • Precisely customise surrounding objects with great accuracy to give you a complete and accurate picture of your solar setup.
  • Produce a 3D animation of shading over a day or a year.

How We Estimate System Performance



As specialists in solar energy since 2008, we use only the most intelligent software, innovative products and combined with our years of experience and expertise to recommend the most cost effective energy saving solution.

Calculations are based on a number of key factors including geographical location, orientation and inclination. We use state-of-the-art digital equipment to model your proposed system: PV Sol Expert is the industry-leading simulation software that enables 3D visualisation and accurate shading analysis. This program considers every factor including the site´s orientation to south, angle of the pitch, and the efficiency of the proposed modules and inverters. The software measures the last 10 years of local meteorological data to give the most comprehensive performance prediction possible.

Energy Assessments

Feed-In Tariff?

Domestic Energy Performance Certificates are required for domestic solar installation and must be a band D rated or better prior to installation of solar to claim your feed in tariff, we arrange your EPC and the cost would be absorbed into the cost within your installation. However, If your EPC is a band E, F or G you will need to carry out energy efficiency improvements before applying for the Fits or receive the lower rate tariff.

Why Is This Now A Requirement?

This requirement was introduced by the UK Government to ensure homes meet minimum standards of energy efficiency before encouraging solar PV uptake. Reducing energy demand is one of the most cost-effective ways of reducing carbon emissions and therefore should be prioritised before installing microgeneration technologies such as solar PV.

What Is An EPC?

Tells you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient). They inform the person using the building how costly it is likely to be to heat /power, and what carbon dioxide emissions there will be. Once produced, EPCs are valid for ten years. They also state the potential energy efficiency rating if improvements are.

Improving Your Energy Performance?

The only way to be sure of the EPC banding of your property is to pay for a visit from a Domestic Energy Assessor (DEA) for an EPC to be produced. Therefore, you may need to pay for two EPCs if your property is not already a band D or better: one to find out and one after improvements are carried out. Some DEAs may be prepared to create a draft report and then wait until the new measures have been completed before amending and submitting it - check this with your chosen DEA. If improvements are necessary, your DEA should be able to advise you which recommendations will be necessary to take your property to a band D and which will take you beyond.

Frequently Asked Questions

What are solar panels made of ?
Solar panels are made up of cells which have a layer of silicon in them that converts light energy into electricity. There are two main types of silicon, monocrystalline and polycrystalline. Monocrystalline is the most efficient, though panels using this may cost more. Polycrystalline is less expensive; however, the panels tend to be larger and less efficient.
What does PV mean ?
PV is short for Photovoltaic which comes from Latin: Photo meaning light + Voltaic meaning Energy.
Why should I invest in solar energy ?
Solar Energy harnesses the natural power of the sun, not only does it mean the electricity you are using is clean because fossils fuels aren't burned to make it, it is also renewable and abundant. You can also save money as you are not forking out for ever increasing energy bills and Government incentives can help you even more.
How much do Solar panels cost ?
This does depend on a lot of variables but for a 4kW system, which is most commonly installed on a domestic property you should expect to pay in the region of £6,500. Contact us now for a free no-obligation survey to find out more.
Is Solar still a good investment ?
Yes! Solar is still a great investment, for commercial systems we always design our systems around your energy usage to maximise the financial benefits. The price of energy will continue to rise, solar energy will ‘futureproof’ your company against this.
How much energy does a Solar array produce ?
Each kWp of solar PV will produce anywhere from 800 to 1200kWh per year. There are a lot of factors which determine this figure but we can produce an accurate estimation based on historic weather conditions at that location and the system specifics such as pitch of the roof and which way it faces.
Does the roof have to face South ?
No, panels can face any direction apart from North, the yield on a south facing system is traditionally higher however an East/West array will generally produce a lower yield but for more hours in a day as the sun will catch each roof in turn as it traverses the sky.
What happens if things go wrong ?
Empower Energy are here to help you in the unfortunate case of something going wrong. The panels themselves come with a warranty for efficiency of 20-25 years. Our inverter systems normally come with a standard 12 year warranty but we can extend this very easily to 20 years.
What is an Inverter ?
Solar panels produce what is called Direct Current or DC for short. An Inverter’s job is to take the DC current and transform it into a power source that you can use; Alternating current (AC for short).
What make of inverter do you install ?
We recommend the Solar Edge Inverter system, with almost every other inverter the panels are linked in a similar way to Christmas tree lights, if one fails or does not work properly, it will affect the rest of the system. So, for example, if something shades one panel, this will affect the performance of every other panel attached. With our system, each panel works independently and at its maximum efficiency and is not affected by its neighbours. This can produce a higher overall system yield than other inverter systems. Our system also can monitor each panel individually, so if there ever is an issue, we will know about it immediately. More often than not, with a traditional inverter the first time someone realises there is a problem is when they submit their generation readings every quarter to the energy supplier.
