When in the planning and design stages of a solar PV project, you may come across the term export limitation. Essentially the process involves fitting a device to cap exported power going from the solar system to the grid. But why would you want or need one? Read on to find out...

At present, electric car charging is simple: you plug in and top up the battery. But many predict that in the future, EVs will have a more symbiotic relationship with our national electricity network. Enter vehicle to grid charging.

A perennial source of confusion when researching solar PV is peak performance. We regularly classify solar systems by their peak, their kWp. But does a system ever reach its peak? In very hot weather over the summer, system owners often observe a drop in performance - so is the peak power in solar panels even significant?

Spirit Energy is delighted to have been part of bringing renewable energy generation to the Natural History Museum in Tring.

For many commercial flat roofs, we install solar PV with Van der Valk mounting. It’s high quality kit, produced in the Netherlands, that offers flexible layouts, compact ballast, quick install time and affordable prices.

Read on for more on the challenges of flat roof solar and why we recommend Van der Valk.

A couple of months ago, we announced that we would be offering our free CPD training online during the coronavirus restrictions. Since then we’ve been running sessions and have been astounded by the interest and enthusiasm from people keen to learn about renewable technologies - and pick up some new skills in lockdown.

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.

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?

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.

To give this some context, 1GW of PV requires around 3,500,000 solar panels and should output enough to power around 250,000 homes.

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.
