Monitoring Solar Export and Self Consumption

Mark Golding · 16 Jun 2021

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.

Living with Solar Panels: One Year On

Mark Golding · 17 Mar 2021

Last February, when the world was a very different place, Spirit installed SunPower panels in the roof of my new home - read all about the installation process here.

So it’s been just over a year now that I’ve been living with solar panels. Although not the best of years, it has been nice to work from home to maximise the use of my own solar energy. But how is my PV system doing? Has it performed anywhere near what my quote promised? And how have my behaviour, bills and carbon footprint changed?

Upgrading Your Home Battery to Backup

Mark Golding · 25 Mar 2020

In light of the recent news, the idea of being grid independent with your own power cut protection has become a lot more attractive. 

We have had a number of customers interested in upgrading their solar PV or battery systems to protect them from power cuts. As we mentioned in a previous blog, a solar PV system alone will not protect you from an outage. With no batteries, if the power goes out, your PV system will switch off. This is a safety mechanism so that you do not discharge any excess PV energy to the grid and seriously injure someone if they are working to repair the grid near your house!

Even if you have a battery, some of them will not be able to island your property from the grid, which is the crucial step needed to have a backup system. Batteries need to follow strict DNO regulations to operate during a power outage as well, and will always need prior grid permission before installing.
