A DIY solar installation cannot be MCS certified. This will limit your choice of export payments, currently only Octopus pay non-MCS installations for exporting.

How much is exporting worth?

Assuming generation of 3000 kWh per year, without a battery and without shifting too much usage into the day, you could expect to export 1500 kWh per year.

Average rate: 4.6p/kWh = 1500 kWh x 4.6p = £69 per year.

Best rate: 16.5p/kWh
1500 kWh x 16.5p = £247.50 per year.

Therefore if you do not switch to a provider that accepts non MCS installations such as Octopus, your DIY solar installation could miss out on £247.50 per year.

Installing solar panels involves electrical wiring, design considerations, and often working at height. Without proper knowledge, you might make mistakes like incorrect wiring or poor panel placement, which can reduce efficiency or create safety hazards (e.g., fire risks from faulty connections).

To mitigate these risks - create a well designed system or purchase a solar design from us. Only use high quality solar panels.

Quality solar panels are connected by push fit MC4 connectors, these have a pleasant click when connected properly. In reality it would be difficult to get this wrong.

Always use a qualified electrician for connecting the inverter to your home and get them to sign it off. (Important they sign it off).

Working from height - use scaffolding and where appropriate protective equipment.

Working on rooftops and handling high-voltage electrical components can be dangerous. Professional installers are trained in safety protocols, while DIYers might overlook critical precautions, risking falls, electrocution, or injury.
