Should you retrofit a solar energy system?

Let’s say you’ve owned a solar energy system for several years, and over time, your energy needs have expanded. Whether you need more power to charge a new electric vehicle or because of increased home consumption (maybe you invested in a new heat pump), there are many reasons why people may want to retrofit an existing solar energy system.

Can solar panels be installed on a trussed rafter roof?

Additional loading to a roof structure constitutes a material alteration if the loading to the roof is increased by 15% or more. Installation of a single row of solar thermal or PV panels on a modern trussed rafter roof of up to 9m span is generally considered acceptable, without further structural investigation.

What types of roofs can I install solar PV on?

Our solar PV installers, roofers and electricians have carried out installations on most types of roofs, including commercial roofs and flat roofs.

Why should we retrofit our homes?

With the cost of living on the rise, it’s more important than ever that we find effective ways to reduce our gas and electricity usage, while benefiting the environment by reducing our carbon footprint. Retrofitting homes is vital for the UK in order to achieve its energy security, fuel poverty and climate change goals.

How do I get advice on retrofitting my home?

In particular we provide a valuable service for people at the start of their retrofit journey and who are seeking initial advice. A good first step is a straightforward phone consulation. This enables householders to understand and explore their options for retrofitting their homes without the need for an in-person visit.

Should solar panels be added to a cut roof?

Any proposed loading increase in both historic and more recent cut roofs should therefore be investigated by a structural engineer. The addition of solar panels should not affect the positive wind pressure acting on roofs, as they are aligned to the profile of the roof.
