Spirit’s Year in Review 2021

George Riley · 15 Dec 2021

Once again we’re taking a look back at a year that’s been anything but ordinary. Changes have come thick and fast, in our daily lives, the renewables industry, environmental legislation and Spirit itself.

Read on for a roundup of all that’s happened in 2021...

Half Cell Solar Panels: More Power, Better Shade Tolerance

George Riley · 13 Dec 2021

The solar manufacturing industry is devoted to trends - from bifacial to PERC - always seeking ways to maximise energy generation. One technology that’s seen a meteoric rise in the last few years is half cell solar panels (or half cut solar cells), on track to become near ubiquitous across PV modules.

Carbon Intensity of Electricity Plummeting due to Renewables

George Riley · 03 Nov 2021

This week sees the opening of COP26, the Covid-delayed climate conference where world leaders are supposed to agree plans to meet the Paris Agreement and limit global heating to between 1.5-2°C. Governments have been scrambling to come up with commitments and pledges in the run up to the Glasgow gathering, with ‘net zero’ the phrase du jour.

One such announcement is that the UK will run on carbon-free electricity by 2035. So we decided to dig a little deeper into the carbon intensity of electricity to see how it’s changing, and what the future of renewable energy holds.

Van der Valk Ground Mounted Solar Panels: A Cost Efficient Alternative

George Riley · 13 Oct 2021

We’ve written before about the possibilities of domestic ground mounted solar panels, and now there is an exciting development that could make these types of installation even more affordable. By essentially using the same mounting systems we use for flat roof PV, we can install Van der Valk ground mounted solar panels to cut time and costs for our clients.

Let’s take a look at how it works.

Spirit Energy Wins Tesla Installer Award

George Riley · 07 Oct 2021

We’re thrilled to announce some exciting Tesla news (and it’s not Elon Musk’s new robot). Spirit has won Tesla’s Performance Excellence Award!

This recognises our work installing hundreds of Powerwalls to the exacting standards that enable us to be a Tesla Certified Installer. Much to our delight, the company also highlighted the value of our informative, impartial content in educating people about renewables and energy storage.

Heterojunction Solar Cells Boost PV Efficiency

George Riley · 08 Sep 2021

The world of solar cell development is a mass of competing technologies: an alphabet soup of acronyms and jargon. If you need to know your n-type HJT from your PERC P-N junction, this is the blog for you.

Heterojunction solar cells are one of the technologies touted to maximise potential PV panel efficiency. They are a combination of classic crystalline silicon and amorphous/thin film cells, theoretically providing the best of both worlds.

Solar Panel Recycling Solutions

George Riley · 02 Sep 2021

Not many PV panels have yet reached their end of life, but this is likely to accelerate in the 2030s as early systems (particularly those installed during the FiT boom) begin to reach old age.

Some panels, however, do get damaged, malfunction or are replaced for newer modules, becoming complex electronic waste.

What happens to the modules next is vital to ensuring solar remains one of the most sustainable forms of energy. The good news is that work is underway to tackle the complexities of solar panel recycling...

Accelerated Loss of Mains Change Programme: What You Need To Do

George Riley · 19 Aug 2021

If you own a large generator, you may have received a letter recently about the Accelerated Loss of Mains Change Programme. This is related to an upcoming regulation change that may affect you and require you to make a change to your system.

Checking in on Old Thorns Hotel's Solar Installation

George Riley · 12 Aug 2021

We’re delighted to share a look behind the scenes at one of our recent big commercial installs: a huge 217kWp solar PV system at Old Thorns Hotel in Liphook.

Old Thorns is a vast resort with a golf course, spa, bars and restaurants, over 150 rooms, and self catering apartments. With such a lot of activity on site, energy demand is substantial to say the least. Solar PV offered a chance to cut down the club’s electricity bills, while also becoming a more sustainable venue.

N-type Silicon Solar Cells: The Future of Monocrystalline PV?

George Riley · 21 Jul 2021

Photovoltaic technology is forever changing, as researchers and developers pursue new ways to maximise performance. In recent years there has been an increasing focus on n-type silicon solar cells, which are doped with phosphorus rather than boron. They have the potential to reduce cell degradation and improve solar generation over the system’s lifetime. As such, n-type cells are being adopted by more manufacturers and may come to dominate the market...
