ZLC Energy

The process of installing the solar panels was surprisingly quick. In a period of just over six weeks, we went from the initial consultation to final testing. Solar panels on the roof of our factory provide 20% of our power and reduce our carbon footprint by over 88,000kg of CO2 a year. The rest of the power we need is undercontract from certified renewable sources. Given that all the heating in the factory is from biomass, we can lay claim to being one of greenest factories in the UK.

ZLC installed a 4KWH east-west solar panel setup on our home in 2012 at a cost of £6769. The installation was clean & neat. In the first year there were problems with the inverter. Their response was always rapid & helpful & the issue was finally resolved by the software being upgraded. Since then there has been no problem & the installation has functioned without further attention. In the last year it produced 3516KWH, returning me £689, a return of a little over 10% on the original installation price which is of course tax free so it's equivalent to 12.5% invested anywhere else. We have also benefitted from a saving on our mains electricity usage. In the last year we used only 1225kwh at a cost of £234, in fact our total power bill for both electricity & gas came to just £526, so we're actually making more money on power than we spend! Sorry I don't have a figure for our electricity use before 2012 to give an exact comparison, but as you can see the solar installation has worked well for us. So, would I recommend ZLC? Absolutely! Their service when things went wrong in the first year was exemplary & they persisted till the problem was fixed. It's been good that they've kept in touch since, another indication that they really care about what they do.
