How to Get 5% VAT on Solar Panels

George Riley 04 Oct 2019

Another week and another upheaval in the world of solar… While the world wakes up to the imminent threat of climate breakdown, our trusty government has decided it’s the perfect time to hike the VAT on solar PV installations.

The Carbon Footprint of a Solar Panel

Erica Charles 27 Sep 2019

In the wake of the largest climate protests the world has ever seen, we have dug a little deeper in our own back yard to assess the ‘life time’ carbon footprint of a solar system...

Solar Tiles vs Solar Panels

George Riley 12 Sep 2019

With the increasing threat of climate change urging many of us to cut back on fossil fuels, solar is ever more appealing. It’s a technology that empowers individuals to supply themselves with clean, renewable energy at an increasingly affordable price. Innovation in this industry is constant, so let’s see how one of the developing trends in PV stacks up by comparing solar tiles vs solar panels.

Solar Panel Maintenance Checklist

George Riley 06 Sep 2019

One of the most appealing aspects of solar PV is that it requires very little maintenance in return for decades of functioning lifetime. With no moving parts, solar panels aren’t put under the mechanical stresses inherent in other generators. But the system is a significant investment - with most of its return based on using its electricity - so a little upkeep is worthwhile to ensure it’s always performing at its best.

Types of Solar Panel: Which Should You Choose?

George Riley 08 Aug 2019

It’s important to do your research when planning your solar system, but the sea of technical terms can soon become overwhelming. Let’s address some of those you may come across when comparing types of solar panel - and see how those types stack up.

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.

Black Solar Panels

George Riley 11 Jul 2019

Why are solar panels blue (usually)?

The standard solar panels that you see most commonly on rooftops are a shimmering blue colour. This is because they are made from polycrystalline silicon - lots of crystals melted together.

But you may have also seen black solar panels - these are monocrystalline. Formed from single silicon crystals, they have a greater efficiency and (in many people’s opinion) a more attractive appearance.

Are Solar Panels Worth It in 2019? Yes, Solar Power Costs around 9p/kWh!

Erica Charles 25 Jun 2019

This year saw the Feed-in Tariff closed to new applicants, leaving a very different landscape to the heady days of 2010, when the feed-in tariff scheme was first launched and the subsidy was around 43p per kWh. So, are solar panels worth it today?

Speaking purely from a financial point of view, the answer is a resounding yes. Of course beyond the financial, there are many other environmental benefits to be gained from installing solar, installing residential battery storage, driving an electric vehicle etc. Not least because they all contribute directly or indirectly to tackling air pollution, which, we are told, is gradually destroying the nation's health.

Back to the financials. The solar subsidy may have fallen, but so has the cost of the technology. Overall the cost of domestic solar electricity is now around 9p per kWh. This is well below the p average domestic import cost from the grid (which, by the way, increased by 7% in the last 12 months...).

Smart Export Guarantee Coming in January 2020

George Riley 11 Jun 2019

On 10th June, the government finally announced the details of the Smart Export Guarantee (SEG), the system to ensure people are paid for excess generated electricity they send to the grid.

This guarantee is seen as a replacement for the Feed-in and Export Tariffs, which ended on 31st March this year. Those schemes encouraged thousands of installs and helped bring the cost of solar down over 50% since 2011. The aim of the SEG is to continue promoting renewables but without costing consumers. Instead suppliers will have to start bidding competitively for the energy you generate.
