PV solar panels.
Contrary to popular belief, PV solar panels in the UK (Photo-Voltaic) generate electricity even on cloudy days and heat-up your hot water tank too. This versatile technology will still be creating you power three decades from now.
In a nutshell.
PV solar panels produce electrons that are like cats. They'll go where ever the food is better, and in a PV context, that may be battery storage, washing machine, TV or EV charging etc. Electrons will naturally gravitate to where they are needed.
Systems range from a minimum of 1KW to a max of 5KW producing from 750 kWh to 4500 kWh per annum.
An inverter is fitted in the loft space with a wall-mounted display unit to check your current/daily/monthly/annual performance figures.
PV to heating converters and PV and battery storage devices are an option to consider in addition to the current feed-in tariff incentives.

Monocrystalline or Polycrystalline?
Monocrystalline cells.Thin slices cut from a single crystal of silicon with a typical efficiency of 15%. Slightly more expensive, but offer a higher peak output of 280-320 Watts per panel.
Polycrystalline cells.Thin slices cut from silicon crystals with a typical efficiency of 12% and give a maximum output of 180 Watts per panel.
Can PV Power My Home?
PV to hot water converters can heat up a traditional hot water tank using a device that diverts some of your generated daytime electricity toward your heating coil. It's beneficial because it eliminates the need for your boiler to heat your water and is an additional way of benefiting from this fantastic technology.PV to hot water converters
Most homes are suitable for a South/South East/South West facing roof space. Your internal electric board's checked for compatibility and wiring routing, but this can be done through our free "get a quote" service.
No planning permission needed in most cases.Check your roof orientation.
How does this technology work in the UK?
PV solar panel installations are attractive an investment, with the feed-in tariffs and battery storage systems.
The UK receives 60% of the sun's radiation compared with the equator. Each square metre of the UK receives between 900 to 1,300 kWh annually from the sun's radiation each year.Solar radiation map of the UK
How much roof space do I need?
Although PV arrays take a lot of roof space, most homes in the UK are suitable. Additionally, they can be installed using A-frames if roof space is a problem.

How much will a system generate in the UK?
A system would generate approximately 750 kWh/year per kW installed. So a primary 1 kW system would produce around 750 kWh per year, and a 5kW system will provide about 4500 kWh. Introducing Photovoltaic technology is a terrific way of future proofing your home. Use our get 'get a quote' service to receive individualised performance data for your property.

How much will a system cost?
The cost of a PV solar panels installation depends on several factors but usually based on system sizes. A home-survey and consultation appointment can be arranged through our "get a quote" service.Installation quotes
Incentives for photovoltaic solar panels.
The 'Clean Energy Cashback Scheme' also called the feed-in tariffs pay you for all the units of electricity produced (domestic or commercial) regardless of whether it is used in the property or not. The feed-in tariff 15.44 pence per kWh will be paid for 20 years. The amount received from the feed-in tariff depends on what size you get.
Can I install myself?
In most cases no, however, if you have Part P electrical and plumbing skills, then it may be possible to install in a DIY capacity. DIY PV solar panel kits are available.
DIY installing can work out much cheaper. However, you will not be eligible for the generous feed-in tariffs schemes currently available. All eligible installations must be carried out and certified by an accredited MCS installer.Schematics for PV solar panel installation
PV feasibility equation:
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 and accompanying technologies.
(The above equation doesn't take into account any future energy price rises.)
What does grid-connected mean?
The generated electricity, which will vary according to the level of sunlight, means the excess energy produced will be directed out to the National Grid, and you will be credited accordingly.
In this way, the deficit between generation and demand can draw from your electricity supplier as usual.
Do I need planning permission?
No planning permission is needed unless you live in a listed building or conservation area.
What maintenance is required?
The advantages of a PV solar panels, amongst other micro-generation technologies, are that no maintenance is required because it is a 'solid-state' energy conversion process.
I heard fitting is expensive?
With generous, grants available, the increase in your house price after fitting and freedom from energy prices, investment in such a system has now become a real choice for homes across the UK.
Does this technology work on cloudy days?
This answer depends on the technology installed and the density of the cloud. In average cloud density, the sun's energy can make a difference. With very, heavy dark, dense cloud cover, probably not. Use your solar powered calculator out on a cloudy day, and it will still work.
Can I heat my hot water with these panels?
Yes, although it's not a standard piece of kit, you can add additional converters that use your PV solar panels free power to heat your hot water tank. The converters are relatively cheap to install and will give you bountiful amounts of heated water.
Can I sell my surplus energy?
Yes, feed-in tariffs for electric-generating systems (Clean Energy Cashback Scheme) will credit you. The system is time sensitive designed to reward the earlier takers with a more significant feed-in tariff.
Will fitting have a substantial impact on my home?
Once installed on the roof, the internal components do not take up much space inside. Fitting usually can be done within 3-4 days, with installers being polite, clean and tidy.
What size system will I need?
Your requirement depends on your energy consumption rate. You can find this out by looking at your electricity bill and finding your annual consumption.
Do I need planning permission?
Conservation areas or listed buildings. It is worth contacting your local council beforehand.
How long does a photovoltaic system last?
PV solar panels installed in the 1960s are still working today. Photovoltaic panel degradation sometimes used as a sales tool within the industry, but with modern manufacturing, the degradation rate is a minimal consideration when choosing an installer.
Do I need to clean my solar panels?
A quality system will usually have a self-cleaning glass surface. However, depending on your location, and may be more prone to environmental dirt, i.e. Tree resin, urban dust or bird Poo. If these are an issue, then most window cleaners can reach and clean, or you may use a professional solar panel cleaning company.
How does the glass clean itself?
The glass is coated with a microscopically thin layer of titanium dioxide. When ultraviolet light falls on the glass, the coating reacts with organic matter in the dirt, breaking it down. The dust takes readily to water. Thus, when the rain arrives, it spreads uniformly across the surface and is washed away rather than streaking.
