Use our Solar Panel Configurator to establish which solar PV system size you require for your building before ordering.

Energy prices are at an all-time high, and there is the ever growing worry of global warming, meaning there is no better time to invest in solar power.

Engenera Renewables Group is an award-winning company in the renewable energy sector. They have become one of the market leaders in renewable installations, and were recognised as National Solar PV Installer of the Year at the 2019 Energy Efficiency Awards.

With an Engenera solar system you will receive a full solar panel design specific to your building's roof, along with a complete report on your specific system. All systems feature new and improved JA Solar Panels and are installed by a fully qualified engineer then commissioned and tested by the electrical team to ensure it is MCS (Microgeneration Certification Scheme) compliant. Once complete, you’ll receive a handover pack with manuals, warranty information and maintenance advice.

Engenera are covered by HIES, the Home Insulation and Energy Systems Quality Assured Contractors Scheme, a strict accreditation process that ensures high-quality is always maintained.

What is a Solar (PV) System?

Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.


  • Reduce your electricity bills: Sunlight is free and readily available, so once you’ve paid for the initial installation your electricity costs will be reduced. You will receive a tailored report by Engenera highlighting your potential savings.
  • Cut your carbon footprint: Solar electricity is a green, renewable energy source and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year.

How is Energy Generated Stored?

Using a battery storage system allows you to capture generated solar energy that would otherwise be exported to the grid. Your system includes a 5kWh Huawei Battery, connected to a hybrid inverter. This means you can make the most of your free electricity and use it at a time that suits you. The inverter will monitor any export on your system, and will automatically charge the battery if you are producing more energy than you are consuming.

3. A qualified surveyor will visit your property to conduct a complete technical survey within 10 business days upon receiving the above information.

4. Once the survey is completed, the information will be passed to the design team where Engenera will proceed to generate a complete design of your PV system, utilising 3D modelling software within 10 business days upon completion of the survey. Any additional costs will be discussed and agreed at this stage.

5. If a revision to the order is required Engenera will advise on which system is suitable for your property to re-order. You have the option to cancel your order or re-order the correct item.
