Producing Cleaner Energy
for a Greener World

Retain Energy specialises in solar energy and provides nationwide businesses with a seamless design, installation, and maintenance service for commercial solar PV systems. We help companies produce their electricity to help lower their energy costs and reduce their impact on the environment and the national grid.

Either installed on a rooftop or ground-mounted solar panels work by converting sunlight into DC electricity, which is then converted into AC electricity through a series of inverters. This energy is used to power businesses regardless of the size of the organisation or the industry it operates within.

Leading solar equipment manufacturers power our systems and make the most of what you already have to help you generate green energy for your usage or to be sold back into the grid. Retain Energy will collaborate with you to design and install the best possible solutions to achieve your goals, whether essential cost reductions or the vital environmental benefits these projects always deliver.

Thanks to the exceptionally high returns that a commercial solar PV system delivers, this renewable energy technology is one of the most popular sustainable solutions in the UK. Hundreds and thousands of businesses have switched to solar energy to provide clean power for their buildings.

Our expertise and comprehensive approach to solar energy provide industry-leading advice, high-quality solar PV components and installation, and an award-winning service.

Benefits of Solar Energy

Commercial solar PV systems offer many benefits to businesses and organisations in the UK. Here are some key advantages to consider:

Solar Energy FAQ’s

 Commercial solar energy utilises solar power systems in a commercial or business setting to generate electricity or heat.

Commercial solar energy converts sunlight into electricity or heat through photovoltaic (PV) panels or solar thermal systems. The PV panels contain solar cells that capture sunlight and convert it into DC electricity, which is then converted into AC electricity by an inverter and used to power the building. Although more electricity is generated in direct sunlight, the panels still create plenty of renewable energy even in cloudy or overcast weather.

Commercial solar energy offers several benefits. Such benefits include reduced energy costs, decreased dependence on traditional fossil fuels, increased energy independence and security, reduced carbon footprint, and improved public relations.

The cost of a commercial solar PV system can vary widely depending on the size and complexity of it. Other factors contributing to the total cost are location, installation timeframe, and incentives or rebates. A typical commercial solar energy system can cost tens of thousands to millions of pounds – there is such a vast difference.

Yes, there are several incentives and rebates available for commercial solar PV systems, including the federal investment tax credit (ITC), state and local tax credits, grants, and other incentives. These incentives can help offset the cost of installing a solar energy system and make it more affordable for businesses.

The installation period for a commercial solar PV system can vary depending on the size and complexity of the system. Other factors to consider are location and weather conditions. Depending on the scale and scope, a typical installation can take several weeks to months.

Commercial solar PV systems with appropriate maintenance and care can last several decades. PV panels typically have 25-30 years or more lifespan, while solar thermal systems can last up to 40 years or more.


A: Commercial solar PV systems with appropriate maintenance and care can last several decades. PV panels typically have 25-30 years or more lifespan, while solar thermal systems can last up to 40 years or more.

A commercial solar PV system requires minimal maintenance, but regular inspections and cleaning of the panels and other components are recommended to ensure optimal performance and longevity. Any necessary repairs or replacements should be promptly made to prevent further damage or reduced system efficiency.

Commercial solar PV systems can be used with traditional energy sources to provide businesses with a more reliable and flexible energy supply. This is achieved through battery storage systems or grid-tied systems that allow excess energy to be sold back to the utility company.
