Space allocation is a critical factor to consider when installing a solar PV system. On average, a system typically has a size of around 3.7kWp, requiring approximately 20 square meters of roof space.

For optimal electrical output, an unshaded, South-facing roof is preferrable. While East or West-facing roof can still be a viable options, particularly as panels don't require direct sunlight. It is important to note that panels situated on North-facing roofs are not recommended. For context, a solar PV system orientated towards the East or West will typically yield 15-20% less energy compared to one directly facing South.

The presence of nearby structures, trees, or chimneys can cast shadows on your roof, adversely affecting your system's performance.

While finding an unshaded location is preferable, sometimes shading is unavoidable. In such cases, certain solar PV systems can mitigate the impact of shading by utilising 'optimisers', or 'microinverters'. It is worth noting that if shading is not an issue, the use of optimisers is neither necessary nor beneficial, except for the additional monitoring capabilities they provide; they do not increase energy generation.

Solar PV panels are typically categorised as 'permitted developments'. This means in most cases planning permission is not required. Nevertheless, exceptions to this may exist, paarticularly if your property is located within a conservation area, or is a listed building. Therefore it is advisable to consult your local planning office for specific guidance. This is something we ask all our customers to do if they are unsure.

In the event that you are contemplating the installation of a solar PV system in your home, it is imperative to complete a registration process with your Distribution Network Operator (DNO). The DNO is the entity responsible for supplying electricity to your property. This is something that Solar-Techs will complete on your behalf.

For detailed guidance on how to carry out the registration of your new energy system in England, Scotland and Wales, the UK Government provides comprehensive advice.

There will be instances when your solar PV system will generate more electricity than you are able to consume or store. In such cases, the excess electricity is sent back to the grid for others to use.

If you wish to be compensated for this surplus electricity, it is essential to ensure you are enrolled in an export payment scheme with your energy provider. The Smart Export Guarantee (SEG) initiative was designed to financially support small-scale renewable energy producers for the electricity they contribute to the grid, providing certain criteria is met. Embracing solar PV with the SEG in place can result in significantly higher savings compared to systems without it.
