Solar PV-T systems - what are the pros and cons?

There are two main ways to collect energy from sunlight. Both have their advantages and both are increasingly being used by households and industry across the world. A hybrid or PV-T system combines the two approaches into the same panel. Solar PV Solar Photovoltaics (Solar PV) are possib…

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

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?

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?

Posted by Alex Barrett on 27 September 2016 at 12:25 pm

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?

Posted by Alex Barrett on 20 September 2016 at 10:05 am

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…

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 …

Will floating solar PV catch on?

Large scale solar installations can generate large quantities of green energy for use in industry. However the question of where these power plants should be constructed can be a hot topic. Floating solar panels are becoming increasingly popular, with a large number of new projects being built ar…

Why it pays to use a recommended solar panel installer

When you invest in solar panels, you want to know that you will be getting a good deal. Most installers deal reputably with their customers, but there will always be a few who do not. Sometimes a company might not be reliable, other times the deal they offer might actually be a con. Three fra…

Can we develop solar panels that work at night?

Posted by Alex Barrett on 18 May 2016 at 11:55 am

Can we develop solar panels that work at night?

The main limitation of renewable energy technologies is their intermittency. At some times they produce more than enough energy to serve our needs, but this is very dependent on conditions of weather and light which are out of our control. These periods of intense energy production do not always …
