PV solar panels and modern installations for the UK's savviest homeowners

Learn about PV solar panels in the UK's climate that will still be providing in three-decades time.

Outside of the box approach to powering the home.



It's good to know.



In a nutshell.

PV (photovoltaic) cells produce electrons that gravitate to where it's earthed. In a PV solar context, that's your TV, EV, battery storage or credited by an export tariff.



The science bit.

Photons strike cells creating electrons that stream to Earth via your home's wiring network.



Specifications:

1-5kW Monocrystalline arrays.
A display unit is provided to check performance.

Photovoltaic's performance varies depending on atmospheric conditions.

Questions about PV solar panels

How much does PV cost?

The cost of a PV solar panel installation depends on system size and plugin requirements. Our quotation service provides options, prices and professional advice.

What about my roof orientation?

Most homes are suitable with a South/South East/South West facing roof.



Is there enough sunshine in the UK?

The UK receives 60% of the sun's radiation compared with the equator. Each square metre of your roof receives between 900-1,400 kWh annually.

How much will PV generate?

A PV system in the UK will generate approximately 900 kWh/year per kW installed.

A simple 1kW system will generate around 750 kWh per year, and a 5kW system produce's about 4,500 kWh.


How does it work?



Sensible feasibility?

Your yearly electric bill x 30 years (panel lifespan).

+3% (average yearly inflation) equals your future energy costs.

Now compare this figure to the cost of PV solar panels.

This simplistic equation doesn't take into account future price rises.



What happens to surplus power?


When PV is producing excess power, it automatically feeds out to the National Grid and credited for your contribution via your power company.

Why PV in cooler climates?

Actually, photovoltaics work more efficiently in cooler temperatures.

Degradation of the panels occurs much quicker in hotter climates, just like redlining your car engine will reduce its lifespan and efficiency.



Can PV heat my hot water?

PV-to-hot water converters heat traditional hot water tanks by using daytime solar-generated electricity redirected to the heating coil. This device eliminates the need for your boiler to heat water.



Can I install myself?

In most cases, no.

Installing DIY solar panels can work out cheaper. However, installations must get certified by accredited MCS-installers only.

PV solar panel kits are available to Part P qualified professionals.



How much roof space?

Although PV-arrays take a lot of roof space, most homes in the UK are suitable. Additionally, they can be ground-mounted A-frames if a roof is unsuitable.



What does grid-connected mean?

Any excess electricity produced will be directed out to the National Grid, and you will be credited accordingly (if battery storage is not present).

Any deficit between in power generation automatically draws from your electricity supplier as per usual.



Do I need planning permission?

No planning permission is required unless on a listed building or conservation area.



What maintenance is required?

No maintenance is required because PV is a 'solid-state' energy conversion process.



Is fitting expensive?

Fitting costs account for 55% of the final installation.



Do solar panels work on cloudy days?

This answer depends on the density of the cloud. In average cloud densities, the sun can penetrate. With very, heavy dark, dense cloud cover, probably not. As an example, use a solar-powered calculator, and it will work fine.



Can I sell my surplus?

Yes, PV export tariffs will credit you.



Will fitting have a big impact?

Once the panels are fitted, the internal components don't take up much space inside. The overall installation process usually completes within 2-3 days. All MCS-installers are polite, clean and tidy.



What size system is best?

Sizing requirement depends on your consumption rate, roof space and your budget. Various options are available to suit different budgets such as typical 2, 3 and 4kW size systems.



How long does PV last?

Photovoltaics installed in the 1960s are still working today. Degradation is minimal consideration when choosing a system. Monocrystalline solar panels still have an 80% generation capacity after 20 years.



What about cleaning?

PV solar panels are coated with a microscopically thin layer of titanium dioxide during manufacturing. When ultraviolet light falls on the glass, the coating reacts with organic matter to break it down.

As NASA's Mars inter-planetary rovers, Spirit and Opportunity demonstrated perfectly, dirt and dust find it difficult to attach permanently.

With that said, a periodic clean, using de-ionised water, will give an extra 5-10%.



A different perspective.

The combustion engine was the most significant machine developed by humanity, yet for most of its lifespan; lay dormant on the driveway.

When in use, the rev counter varies from 1,000 to 6,000 RPM depending on road conditions and brings its owner a sense of pride (maybe) with usefulness spanning a single decade typically.

The same is correct with photovoltaics. However, the usefulness continues beyond its initial operating time with battery storage.

While operational, the performance counter also varies depending on atmospheric conditions and brings a sense of pride (maybe) with usefulness spanning three-decades typically.

Exciting times ahead.
