Online CPD Training Now Available

George Riley 03 Apr 2020

As we settle into life on lockdown, we’re all finding new ways to keep our businesses running and make the best use of our time. The Spirit team is working remotely, but we’re determined to keep sharing our knowledge, even if we can’t visit companies to deliver our usual CPD sessions.

So, after a bit of testing, we’re delighted to announce that we can now offer online CPD training. Your staff can dial in from wherever they’re based for a virtual session on solar PV, battery storage or EV charging.

And best of all - it’s entirely free.

Solar Panel Cleaning

George Riley 30 Mar 2020

One of the questions we hear often is ‘Do I need to clean my solar panels?’. The short answer - it depends. So when should you invest in solar panel cleaning?

Installing Solar PV in London

George Riley 22 Jan 2020

London has high solar ambitions. The city is committed to reaching net zero emissions by 2050. To reach this, the Mayor aims to install 1GW of new solar by 2030 and 2GW by 2050.

Half Cell Solar Panels: More Power, Better Shade Tolerance

George Riley 11 Dec 2019

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.

Tier 1 Solar Panels: Are They Worth It?

George Riley 04 Dec 2019

When researching solar PV, you may have come across the phrase ‘tier 1 solar panels’. It’s used as a selling point by some manufacturers and installers to demonstrate the reliability of their products. But is that really the case?

Introducing Solar Together London

George Riley 27 Nov 2019

We are very excited to announce that we’ve been chosen as one of two installers for Solar Together’s current round of PV installations in London. Solar Together is a group-buying scheme, enabling thousands of people to sign up for a personal solar recommendation, which they can purchase at a very competitive price.

Our vision since we started the company almost a decade ago has been of a country where every homeowner can generate their own clean, renewable energy. Technology and costs have changed enormously in that time, but a project like this goes even further towards making solar an option for many more people. We’re delighted to be part of this journey.

CPD Training for EV Charging Revs Up

George Riley 24 Oct 2019

The electric vehicle boom is imminent. The government recently pledged £400m investment towards EV charging infrastructure as part of its commitment to net zero by 2050. Emission-free number plates are set to turn green to boost driver benefits, awareness and uptake.

SolarEdge vs Micro-inverters

George Riley 17 Oct 2019

In a perfect world, UK roofs would all face south, with a 35° pitch and no shading in sight. But we don’t live in a perfect world. As solar installers, we have to find clever ways to maximise the potential power from roofs of all make ups, orientations and shaded spots.

This is best achieved by using micro-inverters or power optimisers - nifty bits of kit, collectively known as Module-Level Power Electronics (MLPEs). As that name implies, these bring a degree of power optimisation at the module level (i.e. at the level of each individual solar panel). This means you can get the most from panels under different levels of sunlight (facing varying directions or affected by shading, dirt etc).

But which is the best solution? Let’s focus on our favourite brand of power optimiser, and compare SolarEdge vs micro-inverters.

Viridian Solar Panels and the Benefits of In Roof PV

George Riley 20 Sep 2019

While solar panels are traditionally retrofitted to an existing rooftop, it’s becoming more common (especially in newbuilds) to integrate the panels into the roof itself. With in roof PV, you end up with a sleeker, more attractive result.

PERC Solar Cells: When Are They Worth It?

George Riley 15 Aug 2019

What is a PERC cell?

PERC solar cells are a variation on the traditional cells used in solar panels that offer enhanced efficiency. The acronym PERC stands for Passivated Emitter and Rear Contact or Passivated Emitter and Rear Cell. Over the last few years they have become more and more popular, to the point where they now make up over 40% of the solar technology market and are expected to dominate by 2021, according to the ITRPV.
