You may think that solar PV is an established and accepted technology in the UK, but it’s surprising how many solar panel myths persist. At our last community event, a visitor confidently informed us that ‘Britain doesn’t get enough sun for solar power’, which may come as a shock to our clients, whose thousands of panels have been generating well for the last decade.

So let’s set out the facts to debunk common solar myths, from the misinformed to the absurd.

In a surprise piece of good news, the government announced last week that solar panel VAT will be scrapped until 2027. It’s something the renewables industry has been recommending for years, as a simple way to boost green generation in the UK. And for once our lawmakers have listened!

A smart meter is an upgraded version of a traditional electricity or gas meter that can communicate wirelessly and automatically with your energy supplier. When your supplier installs one, they also give you an in-home display (IHD) - a small screen that shows your usage in monetary and kWh terms, both in real time and historically.

Looking at Google search data, you can see how interest in solar panels has intensified since the energy crisis hit the news last autumn, and surged when the upcoming electricity price hikes were announced last month:

In just a few months, an energy crisis has become a cost of living crisis.

The energy crisis is largely driven by the cost of natural gas, which has rocketed due to global supply issues, Covid, and geopolitical tensions. The wholesale price of gas in January was about 4 times higher than the previous year:

The Smart Export Guarantee (SEG) has now been in effect for over two years, since it came into law on January 1st 2020. It’s the mechanism to ensure solar PV owners are paid for the power they send to the grid, ending the policy void that existed since the Feed-in Tariff closed to new applicants in March 2019.

According to the SEG, energy suppliers with over 150,000 customers must offer an export tariff with a rate greater than zero. The SEG is available for customers with an MCS-certified renewable energy system under 5MW and a second generation smart meter.

With zero as the minimum, at the very least you can’t be charged for being relieved of excess solar power. However, suppliers don’t have to give you very much for it. So how much are they offering in practice?

Powerwall has been around for almost six years now, and one of the reasons we like it is that Tesla is always innovating and improving the product. Often, this comes in the form of over-the-air updates to the battery’s software.

The latest feature is the ability to take your Tesla Powerwall off-grid and supply your home as if there were an outage. This has launched alongside the news that Powerwall is now suitable for off-grid installations. Read on to find out more about both…

More and more of our clients are investing in solar battery storage alongside their PV. In this time of energy crisis and price hikes, it pays to use as much solar power at home as you can, rather than shelling out for grid electricity.

When choosing your storage solution, it’s worth considering solar battery monitors. Whether you’re a techy person or not, you probably want to be able to see what your battery is doing. Physically it won’t give anything away, so the only way you can tell how much energy it’s stored or supplied to your house is via its monitoring system.

‘I would get solar panels, but they’re just so ugly’ is an oft-heard refrain, from those who presumably prefer the polluting aesthetics of gas and coal plants. But they have a point. The traditional solar panels aren’t that pretty (though, we’d argue, no less so than TV aerials, satellite dishes and other rooftop paraphernalia).

The good news is that the days of glittering blue PV are in the past. We now only install black solar panels, which not only look a lot sleeker and more uniform, but generate more electricity. It’s win-win!

Our clients are often keen to see what happens during the installation process ahead of time. As the proud recipient of Tesla’s Performance Excellence award, we’re delighted to pull back the curtain and give you a behind-the-scenes look at a recent Tesla Powerwall installation.
