Solar Panel Installation Part 2 – Installation Day


The scaffolding went up on Monday, with work proper scheduled for the next day. The proprietor, Stuart, turned up with his staff on and quickly got down to the business of the Solar Panel Installation. He needed access to the loft and the garage and so I had to leave him with full access to the house, which is a good reason to choose via recommendations.

When I asked how many days the job would take, Stuart replied that he expected it to be completed that day. Returning home in the evening, the house was empty, so I got out of my car and walked to the rear of my house to view the progress. There it was: a roof adorned with solar panels.

It is worth pointing out that, where I work, the mobile reception is awful and so I cannot reliably receive calls or e-mails. I could have left my work’s telephone number, but am not that well organised, so it was all a surprise. Into the garage I went and there, by the fuse box, was all the paraphernalia of new equipment.

Up into the loft I could see no evidence of work done, so I had no idea how the panels were attached. Finally, in the living room, a sender had been connected to my router, obviously to send the solar panel’s energy generation data.

So that was it. All done in a day and very painless.

Not so quick was the removal of the scaffolding, which took over a week, despite an email to the installer. I was not pleased with this as I consider it a security risk.

Setup and Monitoring


The following description describes the system as set up in my house.

JA Solar 285W Monocrystalline Solar Modules

Theses are the solar panels as fitted to my roof. There are fourteen of them.

Solaredge P300 Optimisers

In order to extract the most energy out of the solar panels, each has an Optimiser, which acts as a DC to DC converter and filters the energy. As I have fourteen solar panels, I also have fourteen Optimisers.

SE 3680 Inverter

The DC electricity is converted to AC electricity, which can then be used within my house. There are both AC and DC isolators in order to facilitate safe maintenance.


This is approved by OGGEM and is used to record the total power that is generated by the solar panels. My electricity supplier needs this in order to calculate how much I am owed as part of the government funding.
