Architectural Solar Panels

At JAR Architecture we have noticed a rise in the number of clients wishing to have solar photovoltaic (PV) panels integrated into their home’s architectural design. Whilst this technology has been around for a number of years, thanks to a mixture of government incentives, falling technology prices and the sharp rise in cost of gas and electric, demand for solar panels has never been higher.

Solar panels transform energy from the sun into electricity. The electricity harvested is converted from a direct current (DC) to an alternating current (AC) current via an inverter (to make it suitable for household use). Inverters are usually installed inside the home (although micro versions are available that fit onto the back of individual panels) and this sends the power to a consumer unit. Adding a battery storage unit allows clients to save the excess energy created during the day (when the sun is at its strongest) for later (i.e. morning and evening when demand is greater but solar gain is lower). Any electricity not used can be sold to the national grid through the Feed-In-Tariff (FIT).

Most solar panels are fitted to a property’s roof, ideally one that’s on a south facing elevation and offers a 30-to-40-degree pitch to ensure maximum solar gain. When designing a new build home / extension where a client wishes to install solar panels the sun’s position and path will be carefully considered from the outset and the roofline designed with this in mind. This ensures that the solar panels work as efficiently as possible for our clients and are a fou

There are several solar panel products available:

On-roof solar panels

This is where the solar panels are fitted in to a mount that’s anchored to the rafters. This method is mostly suited to retrofits, as it involves minimal disruption to an existing roof. The panels sit slightly proud of the existing roof to provide a ventilation gap.

In-roof solar panels

With this method the panels are fitted into a frame so that the panels are flush with the roof, with a flashing kit to provide waterproofing. This gives a sleeker finish and is often preferred where a new roof is being built / the existing structure is already being re-roofed.

Solar tiles

Solar tiles are an alternative to panels, they are virtually invisible (which makes them an ideal choice for a conservation area). Although more expensive than panels there are some on the market which are compatible with standard slates.

Ground-mounted solar photovoltaic panels

An alternative to roof panels are ground-mounted panels (which sit in a frame in the garden).
