Adding More Solar Panels to Your System: What Changes?

Mark Golding · 01 Dec 2021

We often get enquiries from people who already have solar panels installed on their roof, but are keen to increase the amount of renewable energy they can produce. This might be because they had a battery fitted, or maybe their consumption has gone up with a new heat pump or electric car.

So what steps are there to overcome if you want to add more solar panels to your existing system to try and reduce your electricity bills even further?

OZEV Grant Closing to Most Homeowners

George Riley · 10 Nov 2021

For the past few years, electric car owners have benefited from government support to buy their new chargepoints. But all this is set to change early next year.

The Office for Zero Emission Vehicles (OZEV) grant, or the Electric Vehicle Homecharge Scheme (EVHS) as it’s officially known, is closing to most homeowners.

It’s done its job, as the UK now has at least 300,000 private residential chargers (as well as over 26,000 public charging stations). Additionally, the government plans to make EV chargepoints compulsory in new build properties with parking spaces.

Why Are Electricity Prices Rising?

George Riley · 27 Oct 2021

Getting your latest electricity bill is rarely a fun experience, yet it seems to become ever more painful. With wholesale prices soaring, the energy industry is in turmoil and we will all end up bearing the financial brunt.

On top of this, the national grid has undergone a huge transformation in the past decade from coal-heavy to embracing wind and solar, the costs of which have crashed. So there’s a logical disconnect - why are electricity prices rising if renewables are getting cheaper?

Investing in Solar Energy and Renewables on a Budget

George Riley · 20 Oct 2021

At a time when we’re facing parallel crises - soaring energy bills and a destabilising climate - more of us are keen to start investing in solar energy and other renewable technologies as a way to take personal action.

Home renewable generation is a reliable way to insulate yourself against the electricity price hikes and potential power shortages, while also tackling climate change. But the stumbling block is often the upfront investment required. So we’ve put together some suggestions on how to invest in solar panels and other forms of decarbonisation, broken down by the budget you may have to spend.

Energy Crisis: Price Hikes and the Power of Solar

George Riley · 29 Sep 2021

Our industry rarely makes national news, but in recent weeks headlines have been dominated by the ‘energy crisis’. The crisis has hit energy suppliers across the UK, and in turn will affect all of us who buy energy from the grid. Escalating gas prices are crippling companies - millions of customers’ suppliers have already gone bust, with speculation that only 10 energy firms might survive the winter.

So how has this energy price crisis happened and what impact will it have on households with solar panels? And perhaps more importantly, can renewables help prevent a crisis like this in the future?

Spirit Returns to Reading Climate Festival

George Riley · 15 Sep 2021

This year may be remembered as the moment when the effects of climate change hit home. We’ve seen a summer of deadly wildfires, floods and heat domes across the globe. The IPCC published a landmark report on climate science, concluding it is ‘unequivocal that human influence has warmed the atmosphere, ocean and land’, causing ‘widespread and rapid changes’ to the environment. In November, world leaders will descend on Glasgow for COP26 to discuss how they can try to limit global heating and its impacts.

It’s easy to feel helpless in the face of the challenge to protect Earth’s habitable climate, but we’re determined to do all we can to empower individuals to take action where they can. With that in mind, we’re delighted to announce that we will be returning this month to Reading Climate Festival.

Solar Car Chargers: The Best EV Chargepoint for PV

George Riley · 17 Aug 2021

With petrol prices at an eight-year high and new fossil fuel powered vehicles due to be banned by 2030, the age of electric cars will soon be upon us. For those of us lucky enough to have a driveway, we can charge up our electric cars at home, making the most of time of use tariffs to slash costs further. But what’s even better than cheap charging? Free charging from the sun!

Solar panels make a great companion to an EV, allowing you to use the car’s substantial battery to absorb excess solar power so you can drive on sunshine. But what are the best solar car chargers to make for an easy peasy EV-PV experience?

Do Solar Panels Increase the Value of Your House?

George Riley · 04 Aug 2021

With the sun finally out (in passing), you may be wondering if now is the time to join the solar club. Panels are better looking and more powerful than ever before, energy bills are spiking, and perhaps your neighbours are charging their new electric cars from the sun.

But if there’s something holding you back, it may be that classic British concern: property prices. So today we’re going to try and answer the question... do solar panels increase the value of your house?

What Affects Solar Panel Output?

Mark Golding · 28 Jul 2021

Today we’re going to take a look at a real world example of an average 4kWp domestic PV system we have installed to understand what affects solar panel output, including factors such as weather, season, angle and orientation.

We’re going to put the batteries, EV chargepoints and hot water units to one side and consider a house with only solar panels fitted. The problem with this setup is that unless the energy is used as it’s generated, it will be exported. This means to get your best payback, you should switch on the dishwasher while it’s sunny, rather than at night.

To get the best annual output, your system would ideally face south at around 35 degrees. The height of the sun in the sky moves quite a lot over the year, so getting the best possible output will not be attainable without a very expensive and complex trackable mounting system. Generally it will always be a compromise on the roof space, orientation and pitch available to you.
