How many panels will I need?
As a general rule of thumb, one Genersys solar panel will provide enough energy to heat a 100 litre hot water cylinder.
It is not very sunny today. Will the Genersys system work?
Although they work best in direct sunlight, very good performance will be given in the indirect light (or diffuse radiat...
Will the system work at night?
No, the system only works in daylight. At some times of the year there is insufficient daylight and that is why your sys...
What is quality in a glazed solar panel? -Download the guide to choosing quality solar panels here.The Genersys guide to
solar panel

Genersys Plc have served the cause of carbon free solar energy long enough to see many competitors come and go, some offering lots of hype and others simply misleading.

It has created a confusing market, where Government has failed to provide adequate measures of how a solar system should be graded (although Genersys have actively tried to improve this through positive campaigning and as members of the Solar Trade Association).

But it can be hard to compare products, especially something that involves lots of technological buzzwords but that is important to the future of the planet as renewable energy. In an effort to help the consumer win by choosing quality over hype, we have produced a check list guide to buying solar panels.

So when comparing renewable energies, demand the following:
  • 20 Year Warranty
    Choose a system backed with a world class warranty from a manufacturer that honours both the performance and corrosion of the solar panel.
  • Performance
    Choose high performance to ensure quicker return on investment and efficient energy saving. Genersys 1000-10 solar panel generates in excess of 1.2 MILLION watts of thermal energy a year, per panel, in just 2m² roofspace.
  • Build quality
    Read horror stories of wind turbines blowing off in the wind or interfering with TV reception? Ensure your renewable energy is a proven, reliable technology and is built as strong as possible, from high quality materials to resist weather corrosion -just like Genersys solar panels.

  • Carbon savings
    Has the manufacturer of your solar panel minimised it's carbon footprint to maximise it's carbon savings efficency? Demand renewable energy that can dramatically reduce your carbon footprint. In the near future such savings could earn you tax credits.
  • Return on investment
    Does your renewable energy offer you over 35 years of financial benefit and proven to add value to your property? Genersys solar water heating does.
  • Buy from a trusted source
    Can you trust the person selling your system or the contractor who you will trust to install it? Does your manufacturer or reseller invest time and resources into building a Trusted Installer Network like Genersys?
  • Local support
    Does your supplier have a good support structure? Can issues be resolved quickly and does the system require any maintenance?
Our 'guide to solar panel technology' is available on request or downloadable in PDF format here. We would be delighted to help if you have any specific questions, so please call our London head office and talk to Jodie or any member of our friendly staff on:
