Homeowner Blog

Whether you’re looking to buy a house with solar panels or it’s come time to sell your property and its PV system, you may have some questions. We’ve gathered the common queries to answer based on our years of experience supporting solar PV owners.

The government has plans to phase out petrol and diesel cars, with sales of new combustion engine models to be banned by 2030 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.

We’re regularly contacted by customers, who have received an unsolicited call or letter from another company, offering them a ‘free solar panel health check’ or warning about their solar PV system being at risk of failing. This is a common scam.

Is now the time to buy an electric car?

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 (24^th March 2020) showing a decrease of about 8% from the monthly average.

In light of the recent news, the idea of being grid independent with your own power cut protection has become a lot more attractive. 

We have had a number of customers interested in upgrading their solar PV or battery systems to protect them from power cuts. As we mentioned in a previous blog, a solar PV system alone will not protect you from an outage. With no batteries, if the power goes out, your PV system will switch off. This is a safety mechanism so that you do not discharge any excess PV energy to the grid and seriously injure someone if they are working to repair the grid near your house!

Even if you have a battery, some of them will not be able to island your property from the grid, which is the crucial step needed to have a backup system. Batteries need to follow strict DNO regulations to operate during a power outage as well, and will always need prior grid permission before installing.

We’d like to reassure you that we are determined to serve our customers and continue driving the switch to renewable energy during the COVID-19 outbreak.

We are following government advice to keep our staff and customers safe, and will update you on any changes to our operations.

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.

Many of our customers are keen to use as much of the solar energy that their home generates as possible in the home. Not only will this reduce bills, it will also increase energy independence.

What is DNO permission and when do you need it?

The DNO or distribution 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 distribution network operators which we are concerned by are Scottish & Southern Electricity (SSE), UK Power Networks (UKPN), and Western Power Distribution (WPD).
