Commercial Solar PV

At Digren Energy we recommend that our clients consider solar PV systems and we offer a consultancy service to ensure that a solution is offered that fully meets their needs. 


Our aim is to provide you with an overview of Solar PV systems and give an idea of the different types of systems available. Before, putting any system in place it is imperative that you fully understand what your requirements are (consumption, load, hours of operation, peak and more) and also to fully understand what limitations are involved. For this it is important that you first know what Solar PV is and how it works.

What is Solar PV?

Solar PV is a renewable energy technology based on capturing sunlight to generate electricity. This energy is generated by photovoltaic panels installed on a site and is usually then stored in batteries, or directly into the company's electrical system.

Benefits of using Solar Energy in Business

Reduce energy costs:


Solar energy is a cheap renewable source of energy and can therefore significantly reduce electricity costs for the company.

Reducing grid dependency

By generating its own electricity it does not depend on traditional energy sources.​

Reduce carbon emissions:

Power generation will be clean and carbon free.

Increased profitability

By reducing electricity costs and increasing efficiency, solar energy allows the company to increase its profitability.

Potential monthly output of a PV system

PV systems will produce much more energy in the summer months due to longer
daylight hours, clearer weather and the sun being higher in the sky. A PV design should clearly show the potential monthly output of the system.

This example chart shows the expected output per month for a 72 kWp PV system based on PVGIS data from 2017 - 2020. Direction of panels is due South and the panel is tilted 30 Degres from horizontal.

* Note that this is potential output, if the energy cannot be used in some way e.g. direct use, storage battery or export, the PV system will automatically limit output.

Types of Solar PV Installation Options

Roof Mounted Applications​

Roof-mount solar panels are a good choice for most commercial properties that naturally faces the sun. They are especially beneficial on larger commercial facilities, in fact, any building with a large roof that is easy to access has the potential for a solar installation. Solar panels can be mounted on slates, asphalt, sheet metal, tile and practically any other type of substrate, on both flat and sloped roofs.

Key benefits of roof-mount solar:

  • Easy to integrate into your business

  • Use existing space

  • Can be installed with minimal disruption to your property

  • Quick and easy process

  • Reduce wear and tear on your roof

Disadvantages of Rooftop Mounted

  • Needs good sun exposure

  • With a small roof, the installation of panels is limited

  • Few panels generate few electricity

Why engage with Digren Energy?

Our stance on energy management is very simple. We treat energy as a resource not a commodity and therefore we believe that if you focus on energy reduction then all the other pieces fall into place (cost reduction, carbon reduction, improved sustainability and more).

If you are in a position to microgenerate all or a part of your energy requirement this opens up many opportunities for you. The primary one being that you can put yourself in control of your energy. One thing we’ve noticed from our clients is that those who have micro generation on their site (Solar and/or wind) are far more conscious of energy consumption than those who are 100% grid reliant. It’s the same as a driver of a full EV is more conscious of efficiant driving over a petrol or diesel driver.

Our objective at Digren Energy is to assist you with all aspects of energy management. An important part of this is ensuring that any micro-generation system being considered is best suited to your needs. We do not sell or install any Solar PV product so we are not constrained with manufacturers or distributors limitations. We can help you make the decision which is best for your organisation going forward. We will guide you through the different options and clarify any areas which appear to be vague.

Bear in mind, implementing a micro-generation system is a big step and needs to be done correctly. Digren Energy are here and happy to help.
