The benefits of solar power

By having solar panels fitted to your home or outbuildings you can reduce your energy bills by *hundreds of pounds and reduce the carbon footprint of your home by over a tonne of carbon dioxide per year. A high quality, well installed solar PV system certified by the Microgeneration Certification Scheme (MCS) will entitle you to be paid for the electricity you generate as part of the government feed in tariff scheme. You get paid for all of the energy you generate whether you use it all or not. Any surplus energy you generate is sold back to the grid, further increasing the return on your investment.

To get the optimum performance and generate the most electricity from your solar PV system, your roof should ideally be south facing and pitched at an angle of around 30 degrees. The panels will still work if your roof faces another direction and can be fitted to flat roofs with a frame, but the power generated from the panels will be less. While there’s no need to worry about the gloomy UK weather as panels still generate significant amounts of power even on cloudy days, you do also need to consider whether there are any obstacles that could get in the way of light reaching the panels – such as trees, or maybe next door’s extension. And the more space you have for the panels to be fitted to, the better.
In England, Wales and Scotland you generally don’t need planning permission for most roof-mounted home solar PV systems, but you should check with your local planning officer if your home is a listed building or in a conservation area or World Heritage Site.
Solar energy is free, clean and green. This is in comparison to energy produced from fossil fuel sources which are rapidly being depleted. The feed-in tariff scheme is designed to help the UK meet the EU target of 20% by 2020, thereby reducing our dependence on unstable energy sources.
The UK receives 60% of the amount of solar energy the equator receives. Each square metre of the UK receives between 900 and 1,200kWh of solar radiation each year, making the UK a good climate for solar panels to work. Generating electricity from solar panels is very efficient. Over 95% of the electricity collected from a solar PV system is converted into AC for use in the home and business – this is much more efficient than electricity bought from the National Grid.
Yes, your solar PV will still produce energy throughout the winter. The shorter length of day does affect your output, but they will still be working to reduce your consumption.
At night, when the solar panels are not able to generate electricity, you purchase electricity from your energy supplier as normal.
UK FITs are calculated for an economic lifetime of 25 years, indicating the Department of Energy and Climate Change believes panels will produce for at least that long. The warranty conditions for PV panels typically guarantee they can still produce at least 80% of their initial rated peak output up to between 20 and 25 years.
Once installed, the panels will require little maintenance but need to be kept clean and free from any debris from nearby trees. They should last 25 years or more but the inverter – which links your roof to your domestic supply – is likely to need replacing at some point. Roxon offers warranties on inverters which range between 10 and 20 years.
Since photovoltaic solar panels are primarily made of silicon, there are no dangers of leaking toxins or fumes. However, there are electrical components involved, so exercise caution as you would around any type of electricity. When sunlight shines on the panels, the panels convert sunlight directly into DC (direct current) electricity. The electricity goes from the panels to an inverter, where it is then changed to AC (alternating current) electricity. The AC power is then piped through the regular home electrical system for normal use. Rest assured, a professionally-installed system has all its live wires concealed in conduit or inside of walls where it is completely safe and secure.
The average 4kW solar PV system could reduce the carbon dioxide emissions of the average household by approximately one tonne per year. Throughout its lifetime your PV system will offset around 90 tonnes of CO2. That’s the equivalent environmental benefit, over 25 years, to 2,316 trees planted, 18 cars taken off the road for a year, 0.5 railcars of coal not burned, 34 tonnes of waste recycled rather than landfilled and 1.3 tanker trucks of gasoline not burned.

With a typical household able to reduce its carbon emissions by around one tonne a year through solar energy generation, Roxon has helped homes and businesses reduce the region’s carbon footprint by hundreds of tonnes of CO2.
The Department of Energy and Climate Change recognises solar PV as one of the eight key renewable energy technologies that can help to create a clean, balanced UK energy mix. Versatile and scaleable, solar projects can be developed and installed very quickly and, unlike fossil fuels, produce clean, renewable energy with absolutely no waste or emissions. Put simply, solar PV is a simpler, cheaper, cleaner and all-round better energy solution. Most importantly, it is proving to be a very sustainable form of energy generation.
Energy from the sun can be harnessed and turned into power anywhere a solar panel can be mounted. It is infinite and free and will be around for another 5 billion years – unlike fossil fuels, which are rapidly depleting. It’s only a matter of WHEN they run out, not IF.

Don’t take our word for how good our Solar PV systems are, see what some of our customers have to say

Because we are electricians primarily, the move into solar PV was a logical extension of our regular work.

This matters to our solar PV customers because the best systems are those which have been designed, installed and commissioned by people with the appropriate knowledge and experience. Our customers can be confident that we have the expertise to put things right if and when they need help and, because our team cover the entire Gloucestershire, Oxfordshire, Worcestershire, Somerset and Swindon regions every day, they can respond quickly. If you choose Roxon Electrical for your solar PV system you can be assured we will not subcontract the work to another firm. Therefore, should you call us to discuss your system, we will know it first hand because we installed it ourselves. Most people know very little about the technical side of solar PV. We never exploit this and endeavour to always be clear about what we specify and what a customer can expect their system to do. We are sceptical about manufacturers’ claims and err on the side of caution when calculating a solar PV system’s projected yield and return - so you will not be disappointed but may be pleasantly surprised. We use the procedures recommended by the Renewable Energy Consumer Code, which was set up to protect the interests of consumers. We don’t inflate our estimated yields using claims made by individual manufacturers because they can’t be verified. Nor do we include general inflation in our future yields because that distorts the prediction and does not represent genuine value in today’s money. Solar PV is an important investment and our clients need to know what they are getting in return for their money. We keep things simple, but if a customer wants a more in-depth explanation of how things work, we can handle any question they care to throw at us. Real value means reliability, performance and customer service - none of which are apparent when you’re choosing what to buy. We are confident in what we recommend and don’t buy cheap just to offer low prices. And finally, a vital factor to consider when shopping around for solar PV is that Roxon is a Microgeneration Certification Scheme (MCS) approved installer - and only systems installed by MCS members are eligible to claim the feed-in tariff.
