Pete Dilloway

You may think that Myenergi products can only be fitted into ultra-modern, futuristic homes or large industrial buildings, but as this case study shows, every home can benefit from Myenergi’s eco-friendly products.

Let us introduce you to Pete.

A new home setup

Pete lives in Norfolk and wanted to not only charge his electric vehicle efficiently, but also improve the effectiveness of his home electricity usage.

Pete has the following home setup;

Forty-one solar panels
Two Tesla Powerwall 2 products
myenergis zappi V1 EV charger x2
myenergi eddi power diverter for the immersion heater

The two vehicles Pete wanted to charge at home were a Mitsubishi Outlander PHEV and a Tesla Model 3. The Tesla is a recent acquisition, prior to that, Pete had a Hyundai Ioniq Electric. Just goes to show how adaptable myenergi products are!

Utilising Solar

For Pete, the whole solar/EV philosophy came about by accident. His brother-in-law got a quote for some panels back in 2015 and it seemed like a great idea for Pete and his family to get involved, getting on board with a collective buying deal.

Pete had 28 x JA Solar 250w panels set up, facing south, connected in four strings of seven to two Solis 4.5Kw inverters, which were installed in September 2015. To date they have generated 26.5 megawatts of energy! That would take more than 10 tonnes of coal to generate the same amount of electricity.

Pete and his family talked about utilising some of the PV power but it wasn’t until August 2017 that the PHEV arrived to replace a big old diesel dog carrier! The first Zappi arrived soon after, fitted under the OLEV scheme.

Petes Home with 41 Solar Panels

Super cheap charging

The defining moment came early in the summer of 2018 when It became clear that running an electric vehicle was super cheap!

In August 2018, Pete traded a Prius hybrid for the Ioniq full EV and shortly after, added a second zappi under the OLEV scheme together with an eddi and a Tesla Powerwall.

The setup worked well enough but it was clear that they couldn’t produce or store quite enough power during winter. So in January 2019, Pete maxed out his roof space with another 13 JA Solar 300w panels; 8 facing west and 5 facing south, connected to a Solar Edge 4.5Kw inverter, together with a second Powerwall and backup gateway. This gave Pete’s home the ability to generate 11Kw, store 27Kw hours in the Powerwalls and ride out any power cuts.

An actual powerhouse

Pete calculates that using PV power to charge the Ioniq has resulted in him being paid 1.4 pence per mile to drive it. The Outlander has averaged over 200 miles to the gallon!

Interestingly, while the Eddi tends to be less frequently used, typically getting third or fourth call on generation for power, during the Covid 19 lockdown, it has been getting the lion’s share!

The stats

As of April 5th, 2020;

PV generated – 53.12 KWh
Powerwall took 11.4 KWh
Tesla took 28.04 KWh
Outlander took 1.11 KWh (didn’t need a charge!)
Eddi took 3.37 KWh
Exported 1.8 KWh

All time:
Zappi 1 from November 2017 (mostly Outlander); 4373 KWh, 2837 – green, 1536 – Grid.
Zappi 2 from November 2019 (mostly Ioniq); 1379 KWh, 623 -green, 756 – Grid.
Eddi 1143 KWh, all green.
