We are often asked ‘what is the best solar PV panel for me?’. Unfortunately, it is hard to give one definitive answer to this question as each customer has different views on what the most important factors are and their motivation for investing in solar PV can have a significant impact on our response.
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.

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.

How is COVID-19 impacting our energy demand?
The world is currently going through unprecedented times, with the majority of the population confined to their own homes, practicing social distancing to help curb the spread of COVID-19. This has had a significant impact on our day to day lives, with most working from home, and as a result there has been an increase in daytime energy usage. In a study by Octopus Energy, almost a third of households have noticeably changed their usage patterns, with a daytime electricity usage increase of up to 32%, resulting in an average electricity bill rise of £1.34 - £2.85 per week.
While there has been an increase in domestic energy usage, the national energy demand has decreased due to the number of industries and factories temporarily closing their doors to comply with the government’s regulations. The UK’s total energy requirement is down by about 20%, with the electricity demand on the first day of lockdown (24th March 2020) showing a decrease of about 8% from the monthly average.

Over the past year there have been a couple of fairly large changes which have impacted the payback period of a solar PV installation. Firstly the Feed-in Tariff (FiT) closed for new applicants at the end of March 2019 and then the Smart Export Guarantee (SEG) was brought into effect at the start of this year.
What is DNO permission and when do you need it?
The DNO or District Network Operator is the company responsible for distributing electricity from the National Grid to your home or business. In the UK there are 14 different district networks or DNO regions which are owned by six groups. For our installation zone, the distributions network operators which we are concerned by are Scottish & Southern Electricity (SSE), UK Power Networks (UKPN), and Western Power Distribution (WPD).
Now that Christmas is less than a week away and the new year is just around the corner, it only seems right to reflect on what has been quite an eventful year for the solar and renewables industry.
Why does the solar panel output matter?
When installing solar panels there are many things to deliberate over, whether that be the price or aesthetics, but probably the most important metric to consider is the output. More often than not the price you pay for an installation will be relative to the power output of the system. The rated power output or wattage of a panel represents the theoretical power output under ideal conditions and is a strong indication of the amount of electricity a panel will generate. However; there are factors other than the panel’s wattage to consider when determining its output or energy generation.
