How Do Solar Panel Systems Work?


Photovoltaic (PV) solar panels are able to generate electricity from UV energy from the sun. The only byproduct of this process apart from electricity is heat. In terms of how the solar panel system operates, the PV cells absorb energy from the sun when the sun shines on the solar panel. Solar panels can also operate in cloudy conditions as long as the sun is shining and rain can actually clean the solar panels and make them absorb any sunlight that may be available. Once the sun shines on the solar panel, electrical charges are produced that move due to a field of electricity in the cell, thus causing electricity flow. 

Our installation process is as follows:

    • We install the solar panels on the roof of the property or on the floor around the property.

    • UV from the sun causes the reaction to take place in which electricity then flows from the field in the cell.

    • Electricity is charged from Direct Current (DC) to Alternating Current (AC) via an inverter.

    • The electricity then connects to the property through the main fuse board.

    • You are then able to use this to power your property as you would with other sources of electricity.

    • There are various ways in which you can use your electricity or sell electricity back to the grid if you have excess electricity.

Frequently Asked Questions (FAQs) About Solar Panels

On average, Donegal obtains around 1352 hours of sunlight per year. This means that you can install solar panels on your home or business property and enjoy all of the benefits of solar energy. This is a fantastic source of renewable energy so get in touch with a member of our team to arrange for installation today.

One of the greatest benefits of commercial PV systems is the substantial cost savings. If you operate industrial PV panels, you can sell the excess energy to the utility companies for incurring profits.

We had been considering the installation of Solar PV for quite a while. I visited many commercial premises that had installed solar panels to research the process, before deciding on Alternative Energy as our provider. Jerome, Ronan and their team did a top class job of designing, installing and commissioning our system, with minimum disruption to the every day running of our factory. All the required paperwork and forms were completed for our ESB Network connection and our SEAI grant application. Our phone app allows us to monitor our usage and get live information of solar production. I am now looking at installing a second system on another premises and plan on using Jerome and Ronan once again. Their standard of workmanship is exemplary and I would have no hesitation in recommending Alternative Energy as a solar provider. Mark Birnie Director Shackletons Milling.

The guys were recommended to me by a friend. Price was good and they were lovely to deal with. I'm not usually one for leaving reviews but they went the extra mile so I thought it was only fair. We actually had a faulty inverter out of the box, the guys took up the case with the manufacturer and got us a replacement fitted within a week, so fair play.

Excellent service and excellent value for money. They came on the planned date and installed, tested and commissioned the solar PV panel system over two days. Both the roofing team and the electricians carried out their work in a professional manner. They answered and explained any questions I asked, they discussed with me beforehand what they would do, they explained how the system operates and what apps I needed to download and they tidied up fully when they were finished. I would have no hesitation in recommending Alternative Energy to anyone based on their excellent service and professionalism.
