What Would Happen if the Sun Disappeared?

Even if you don’t know much about science, and outer space in particular, most of us know that that great big yellow thing in the sky is quite important for our existence. The majority of us will realise that without the Sun, things down here on Earth would be pretty cold and dark. However, we were curious to see what else might happen if our giant source of heat and light were to suddenly vanish from the sky.

Our latest infographic explores everything that would happen should the sun disappear, along with a timescale of how long it would take for these things to happen. For example, within eight minutes all the planets would start to travel in a straight line through space because there would no longer be a gravitational pull from the Sun and the surfaces of the oceans would freeze over within a couple of months. Take a look at the infographic below to find out more about what would happen to us and our planet if the Sun were to disappear.if-the-sun-disappeared

  1. Do solar lights really work in winter?works-in-winter

All Solar lights work in winter as long as the Solar panel receives enough daylight to power up the batteries to a point that the light can function assuming no faults.

Many people ask if our lights work at winter after having a poor experience in the past, normally with very cheap budget type lights.

All solar lights use rechargeable batteries and with a good set of Lithium Ion batteries costing upwards of £10 so a solar light is less it’s likely to be very limited in performance.

  1. Why are my solar lights not on dusk till dawn in winter?dusk-till-dawn-solar-lights

“Dusk to till dawn” or “always on” are the most common type of solar lights that run at night until dawn or until the charge in the batteries runs out. However the dusk till dawn description can build unrealistic expectations and here at Solarcentre we try our best not to use that description as the time of year, panel positioning and of course the specification of the light all determine how long the light will operate for.

21 December 2016 is the next solstice and the sun will rise at 07:07 and set at 16:21 in London, that’s 9hrs 14mins of daylight or 14hrs 46 mins night.

 

 

For our premium solar products 1hr direct sunlight can provide up to 1.3hr LED/SMD light output.

Here at Solarcentre we launched two massive technological advances in our solar lights, Power Saving mode, which doubles the light run time by reducing the power going to the LED/SMD bulb.

Our first Dual Solar Panel lights were also introduced on the Kodiak range. Both features combined offer more than 4 times the runtime of comparable lights without these features.

 

 

  1. How do you charge solar lights in winter?charging-in-winter

No matter what time of year solar lights charge in the same way, the main differences between winter and summer is that the length of time between sunrise and sunset reduces.

The sun in the UK is lower in the sky in winter which has two knock on effects. One being that sunlight has more atmosphere for the suns rays to pass through and the other that a solar panel will produce more when pitched at approximately a 45% angle rather than straight up.

Avoiding shadows is particularly crucial in winter as lengthening shadows that may not have been a factor in summer can make a review of a solar panels positioning an essential task in winter.

  1. What are the best solar lights in winter?best-winter-solar-lights

There are many solar lights that are best for UK winter conditions but it really depends on what you need the solar lights for.

Security solar lights with motion sensor are perfect all year round as the lights that only trigger when movement has been sensed, this is how we can make a security lights with 1,400 Lumens (the brightest in the UK). If bright lighting is essential in winter then we always strongly recommend a motion activated light to provide the best guarantee of the light being there when you need it.

Fairy lights of course use far less power and work all year round. Our Lumify fairy lights have a USB top up for if you ever have very long periods of no sunlight or if you’re struggling to get the panel in a good position for the winter sun.

Last but not least our dual panel lights with power saving mode boast the best light runtimes for always on light in winter!

  1. How do you to charge solar lights without sun?solar-lights-without-sun

Solar panels use the energy from daylight and not direct sunlight, direct sunlight provide the best conditions as it’s the least diffused through cloud. Even the angle of the sun throughout the year is massively affected just by the amount of atmosphere the rays need to pass.

Dark thick cloud will absorb far more daylight than thin white clouds and will in turn reduce the output of the panel. So even on a cloudy and rainy day your panels are still working away.

  1. How do solar lights work in the shade?solar-lights-in-the-shadew

As above solar lights still work in the shade without sun but for the best performance, no matter the time of year, solar panels should be angled directly at the sun with nothing in the way to diffuse the light.

  1. Can you use rechargeable batteries in solar lights?battery

All “real” solar lights should have rechargeable batteries to work, the solar panel simply recharges the batteries during daylight and the lights come on once the sun has set.

David Cameron: Told to Support UK Solar

Share Button

davidcameronOver 150 companies have signed a letter which was sent to Prime Minister David Cameron 7th July 2014. The letter is urging him to support the UK’s thriving solar industry and support UK solar farms and providers. Top dog companies that have signed the letter include: Ikea, The Eden Project, and Finesse Energy Ltd. The letter comes after the Department of Energy and Climate Change (DECC) closes their talks about removing the renewable obligation support for solar farms over 5MW. This has been described by some of the leading solar suppliers and experts as a “kick in the teeth”. Without this support the predicted £78 billion per year global solar market (by 2020) becomes an impossible target.

 

Support UK Solar: The Home-Grown Energy Crisis Solution

SolarTradeAssociationPaul Barwell, chief executive of the Solar Trade Association explained: “Solar is a home-grown solution to Britain’s energy crisis. If the government provides a stable policy environment solar will soon be subsidy free. But the government is now proposing to tilt the playing field against large-scale solar, while not taking sufficient action to unlock commercial rooftop solar – that is unacceptable. We urge DECC not to close the Renewables Obligation to large-scale solar and to rethink proposals on feed-in tariffs to allow a meaningful rooftop market which their own Solar PV Strategy recognises has such tremendous potential.”

 

Government Needs to Wake Up to Renewable Markets

SolarCenturyJeremy Leggett, chair of SolarAid and non-executive chairman of SolarCentury added: “Despite all of the incredible achievements of the UK solar industry since 2010, it’s still very clear that the Whitehall mind-set has yet to catch up. Too much of the wording in the current solar consultation has the whiff of Groundhog Day about it. It’s time that the government woke up to the fact that, with stable support, jobs rich UK solar will be cheaper than onshore wind during the next Parliament, opening up immense opportunities for UK PLC and driving down the costs of delivering the 2020 renewable energy target in the process.
