4KW PV (Photovoltaic) Solar Panel Systems

Harnessing the power of the sun to provide the heating and electricity needs of our homes here in the UK is becoming an ever more attractive proposition – not only for environmental reasons, but because it can be financially rewarding in two huge ways!

Install solar panels in my home, here in the UK? You must be kidding? We don’t get enough sunshine!

It’s not surprising if that is the first conclusion many house-owners in Britain come to, because, on the face of it, it must be true. But in actual fact it isn’t.

That’s because the recent advances in the world of photovoltaics (converting the rays of the sun into energy) has led to significant improvements in the ability of solar panels to perform in low-light conditions.

In fact, even if it is cloudy all day the rays of the sun still permeate down through the clouds into the atmosphere providing useful energy that can still be captured and converted.

Here in the UK it is generally accepted that if someone installed a 2.7 kilowatt (kW) photovoltaic system on the roof of their house they would generate about 50 per cent of their total electricity requirements for the whole house every day. That being the case, the logical conclusion is that 4kW system would be needed to generate 100 per cent of the electricity needed for the whole house for every day of the year.

The Cost Of Installing a 4kW Solar Power System At Home

The big question of course; and the answer is it could cost as much as £16,000 to £22,000 for a top-of-the-range 4kW system from a reputable manufacturer, depending on the make you go for. The key thing to consider here is the efficiency rating of the solar panel manufacturer.

The higher the efficiency rating of any given panel (the percentage of the sun being converted by the panel, the best being 15 per cent to 22 per cent max) the better the conversion of the sun’s power into power for your home.

But here’s the good bit before your enthusiasm dims completely – because even though the cost of installation appears high (and may well be for most people) much of the cost will be recouped well within the 25 years of performance-expectancy your 4kW system guarantees.

How?

Well, thanks to a new government scheme called the “Feed In Tariff Scheme” (FITS) you can actually sell the energy you generate via your solar panels back to the national electricity grid at 41 pence per kW supplied. The fact that you will also be saving money on your general electricity bills is what makes installing solar panels at home the attractive proposition it is.

And it is all tax-free.

Some estimates hold that those people installing a 4kW solar power system at their home could generate income of £116,500 by the end of the 25 years the system is guaranteed to last. Place that figure next to the initial installation cost and you can see what a handsome return it potentially provides.

    Although Samsung Electronics has been involved in research and development of solar PV technology since 1987 the company has only really made any significant in-roads into actual manufacture of solar panels in the last few years.

    Despite being tagged in 2008 as the “solar patent king” Samsung still isn’t hitting the headlines for its solar modules, yet it has gone on to enhance its reputation and standing in the electronics industry by becoming the world’s leading manufacturer of LCD’s (liquid crystal displays) and memory chips, and even outdoing Apple earlier this month when it shipped some 20 million smart phones around the world.
