Working from Home with Solar PV

David Woon 01 Apr 2020

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.

Solar Panel Payback

David Woon 13 Mar 2020

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).

Solar Panel Output

David Woon 18 Jul 2019

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.
