Solar upgrades & retrofits

An underserved job

If your system is ten years old, it's probably leaving money on the table

The feed-in tariff drove a wave of installations across Hertfordshire and Cambridgeshire between roughly 2010 and 2015. Those arrays are now reaching the point where the inverter (typically the first component to fail) is at the end of its service life, while the panels themselves have plenty of years left.

It's a job most solar companies aren't interested in, because there's more margin in selling a complete new system. We're set up for it: it's largely electrical work, which is what we do.

If you're still on a feed-in tariff agreement, that income is usually worth protecting. Some changes are neutral, others can affect your arrangement. We'll check where you stand before recommending anything.

• Inverter replacement when the original fails or becomes uneconomic to repair
• Battery retrofit to an existing array, the single biggest improvement for most owners
• Additional panels where the roof and inverter capacity allow
• Fault-finding on systems that have stopped generating or are underperforming
• Monitoring added to older systems that never had it
• Your existing feed-in tariff position checked before any work is agreed
