Can nanotechnology make solar PV 80% efficient?

Solar Photovoltaic (PV) systems are a great way to produce renewable power by converting the energy in sunlight into electricity. However sunlight comes in a wide range of wavelengths, both visible and invisible. The current generation of solar panels are only able to harness a fraction of the po…

Solar PV made my electricity meter run backwards

Solar PV made my electricity meter run backwards

They found me, I don’t know how, but they found me.  Yes, I know, it’s a quote from Back to the Future and of course I do know how they found me. My energy supplier finally worked out that my meter was running backwards because I have a PV system.  I had a 3.01kWp sy…

Will tomorrow's solar panels generate electricity from rain?

Will tomorrow's solar panels generate electricity from rain?

There are potential sources of energy all around us. Any natural system contains energy and in theory we can tap into that energy to generate electricity or work. Something that we don’t currently harness is rain. Unfortunately rainfall doesn’t generate a sufficient volume of water to…

Why is energy storage difficult?

Why is energy storage difficult?

Our ability to generate renewable energy is increasing all of the time. It provides a great, green supplement to conventional power generation technologies. However if renewables are to one day stand on their own then there is an important issue that needs to be considered; Energy Storage. So…

Can we manufacture renewables without fossil fuels?

In order to capture energy from renewable sources we need the right technology. But solar panels and wind turbines are very energy intensive to manufacture. Unfortunately the energy that is used to make renewable systems usually comes from fossil fuels. So can we produce enough renewable electric…

Are solar tiles a worthwhile investment?

Roof mounted solar panels are an increasingly common site on buildings across the UK. Most of these systems are attached to the roof by means of a frame. However many people would prefer that solar panels were integrated seamlessly into their house’s design.  The solution is the roof i…

New solar PV accreditation scheme from BRE

The Building Research Establishment (BRE) launched their new voluntary Solar PV Certification Scheme at their Solar Summit on the 19th July 2016. Although applicable to all solar projects, its target is solar rooftop installations over 50kW (approx. 350m2) which is above the threshold for install…

Will battery storage affect my feed-in tariff payments?

Q. Will battery storage affect my FiT payments? A. A recent question from a YouGen reader about the impact of battery storage on Feed-in Tariff (FiT) payments for solar PV got me thinking. My initial reaction was that FiT payments wouldn’t be affected by storage as FiT payments are made…

How long do solar PV panels last?

Posted by Alex Barrett on 26 July 2016 at 5:05 pm

How long do solar PV panels last?

It can take years for a solar photovoltaic (Solar PV) array to “pay back” its installation cost, so you want the panels to last as long as possible. So just how long do solar panels last? And how does their efficiency decrease across their lifetime? The aging of solar cells can be…

Is the future high speed internet with solar panels as receivers in remote areas? Li-Fi rather than Wi-Fi?

Posted by Jason Ramsdale on 4 July 2016 at 10:15 am

Is the future high speed internet with solar panels as receivers in remote areas? Li-Fi rather than Wi-Fi?

There is a new way of transporting data on the horizon and it's Li-Fi (Light-Fidelity). Boasting speeds 100x quicker than traditional Wi-Fi connections, Li-Fi has a theoretical top speed of 224 Gbps. To put that in perspective it means you could download 10 DVD quality movies, 1600 songs and …
