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?

‘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!

We often get enquiries from people who already have solar panels installed on their roof, but are keen to increase the amount of renewable energy they can produce. This might be because they had a battery fitted, or maybe their consumption has gone up with a new heat pump or electric car.

So what steps are there to overcome if you want to add more solar panels to your existing system to try and reduce your electricity bills even further?

Getting your latest electricity bill is rarely a fun experience, yet it seems to become ever more painful. With wholesale prices soaring, the energy industry is in turmoil and we will all end up bearing the financial brunt.

On top of this, 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?

Our industry rarely makes national news, but in recent weeks headlines have been dominated by the ‘energy crisis’. The crisis has hit energy suppliers across the UK, and in turn will affect all of us who buy energy from the grid. Escalating gas prices are crippling companies - millions of customers’ suppliers have already gone bust, with speculation that only 10 energy firms might survive the winter.

So how has this energy price crisis happened and what impact will it have on households with solar panels? And perhaps more importantly, can renewables help prevent a crisis like this in the future?

With petrol prices at an eight-year high and new fossil fuel powered vehicles due to be banned by 2030, the age of electric cars will soon be upon us. For those of us lucky enough to have a driveway, we can charge up our electric cars at home, making the most of time of use tariffs to slash costs further. But what’s even better than cheap charging? Free charging from the sun!

Solar panels make a great companion to an EV, allowing you to use the car’s substantial battery to absorb excess solar power so you can drive on sunshine. But what are the best solar car chargers to make for an easy peasy EV-PV experience?

With the sun finally out (in passing), you may be wondering if now is the time to join the solar club. Panels are better looking and more powerful than ever before, energy bills are spiking, and perhaps your neighbours are charging their new electric cars from the sun.

But if there’s something holding you back, it may be that classic British concern: property prices. So today we’re going to try and answer the question... do solar panels increase the value of your house?

Today we’re going to take a look at a real world example of an average 4kWp domestic PV system we have installed to understand what affects solar panel output, including factors such as weather, season, angle and orientation.

We’re going to put the batteries, EV chargepoints and hot water units to one side and consider a house with only solar panels fitted. The problem with this setup is that unless the energy is used as it’s generated, it will be exported. This means to get your best payback, you should switch on the dishwasher while it’s sunny, rather than at night.

To get the best annual output, your system would ideally face south at around 35 degrees. The height of the sun in the sky moves quite a lot over the year, so getting the best possible output will not be attainable without a very expensive and complex trackable mounting system. Generally it will always be a compromise on the roof space, orientation and pitch available to you.

In the old days of solar PV, after your system was fitted, the only way to know how much power you produced was from the generation meter ticking up each day, or reading the screen on the inverter.

As inverters got better and integrated with WiFi, they allowed you to track daily, monthly and yearly production figures using your phone or computer. Although, one thing that you could never be sure of is the total amount of PV energy consumed on site.

But times have changed, and there are now much better ways of monitoring solar export and self consumption.
