"I started 1st Call Solar with one simple rule - if I wouldn't accept it on my own house, it doesn't go on yours. Most of our work today comes from word of mouth and second jobs from happy customers. That's how I know we're doing it right."Get a quote from Joe
Four steps from first call to a system that is generating.
We look at the roof, the pitch, the orientation and what you actually use, then tell you honestly what a system on your house would generate.
Panel spec, battery spec, inverter and the full price in writing, with no obligation and nobody sitting in your kitchen until you sign.
Our own team fit it, commission it and register the installation, so your export payments can be set up without a fight.
The 2-year workmanship guarantee is insurance backed, so it still stands even if something were to happen to the company.
Answers to the most common questions we get.
We aim to ring you back the same day during working hours and book the survey around you, usually within a few days.
Yes, both, and with no obligation. You get a written price and one follow-up call. Nobody is going to sit in your front room until you sign something.
It is the standard installers are assessed against, and it is what lets you claim SEG export payments for the electricity you send back to the grid. Without an MCS-certified install, most suppliers will not pay you for your export. We are also registered with HIES and EPBS.
Not necessarily. A battery pays for itself if you use most of your electricity in the evening rather than the middle of the day. If your usage does not suit one we will say so on the survey rather than sell you one.
It covers our workmanship: if something fails because of the way we installed it, we come back and put it right. Insurance backed means the guarantee is underwritten, so it is still honoured if the company is no longer trading. Panels, inverters and batteries carry their own manufacturer warranties on top, which are much longer.
Most are, but pitch, orientation, shading and the condition of the roof itself all matter. The survey is where that gets answered properly, and if your roof is not suitable we will tell you rather than fit anyway.
There is a deposit once the job is booked to cover the equipment, then the balance on completion when the system is commissioned and handed over.
Tell us about your solar install and Joe or one of the team will call you back the same day.
