How Many Solar Panels Are You Allowed on Your House?

George Riley 01 Jul 2020

Some of our clients are surprised to learn that there can be limits on the number of solar panels they can get on their roof, beyond the obvious physical and cost limitations. In fact, for solar PV systems over a certain size, grid permission is needed before installation can go ahead.

In this post, we’ll explore how many solar panels you’re allowed to install without prior permission, and how we can help you determine the maximum possible allowance for your property.

Are Solar Panels Worth It in 2020? Yes, Solar Power Costs 8p/kWh!

Erica Charles 25 Jun 2020

Last year saw the Feed-in Tariff closed to new applicants, leaving a very different landscape to the heady days of 2010, when the Feed-in Tariff scheme was first launched and the subsidy was around 43p per kWh. In October, solar tax rates also got a shakeup, meaning not every installation is eligible for 5% VAT. So, are solar panels worth it today?

Speaking purely from a financial point of view, the answer is a resounding yes. Of course beyond the financial, there are many other environmental benefits to be gained from installing solar, installing residential battery storage, driving an electric vehicle etc. Not least because they all contribute directly or indirectly to tackling air pollution and the climate crisis.

Back to the financials. The solar subsidy may have fallen, but so has the cost of the technology. Overall the cost of domestic solar electricity is now around 8p per kWh. This is well below the 16p average domestic import cost from the grid (which, by the way, increased by 6% in the last 12 months...).

Why Combine Solar PV with an EV?

David Woon 19 Jun 2020

As of Wednesday 10th June, the UK hit a huge milestone of going two months without burning any coal for electricity generation. This is due to a combination of the reduced national energy consumption since the start of lockdown and the high investment in renewable energy over the past decade. Approximately 800,000 homes now have solar PV installed, helping to contribute to the decarbonisation of the grid, while also reducing their energy bills.

As electricity generation continues to decarbonise, the next logical step is for the transport sector to shift away from fossil fuels and towards electric vehicles. Over the past couple of months, the number of vehicles sold has dropped considerably. Electric and hybrid vehicles, however, feature more heavily than usual in the ‘top 10 models sold’ and more Tesla Model 3s have been sold over the past two months than any other car.

With the number of homes generating their own clean energy via solar PV and the number of electric vehicles on the road growing, we thought we’d take some time to analyse the benefits of pairing a domestic solar PV system with an electric car to quantify the potential financial savings.

Is Now the Time to Invest in Solar PV?

George Riley 05 Jun 2020

As the UK begins to ease out of lockdown, many of us are facing some form of financial upheaval. For lots of people, the crisis has resulted in the painful loss of employment or income. But others have been able to weather the storm, or even save money during this period.

With no meals out, little hope of travelling abroad and the daily commute a distant memory, expenses for some of us have dropped dramatically. If you find you’ve saved a chunk of money from abandoned holidays or working from home, this could be a unique opportunity to spend on something significant.

So is now the time to invest in solar?

Hydrogen Fuel for Transportation: The Future?

David Woon 28 Apr 2020

Image source: Joseph Brent.

There is an ever increasing demand to decrease greenhouse gas (GHG) emissions as global awareness of climate change continues to grow. In the UK around a third of our total GHG emissions comes from the transport sector. To try and combat this, the government aims to phase out petrol and diesel cars, with sales of new combustion engine models to be banned by 2035 and a desire for almost every van and car to be zero emission by 2050. At the end of 2018, electric vehicles accounted for only 0.5% of the vehicles on the road. A lot therefore needs to be done if the government’s targets are to be reached.

Why Are Electricity Prices Rising?

George Riley 16 Apr 2020

Getting your latest electricity bill is rarely a fun experience, yet it seems to become ever more painful. 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?
