There is approximately 400MW of solar PV operational in Scotland, equating to 3% of total operational capacity.

As of 2020, there are at least 60,000 domestic level solar PV installations in Scotland with a capacity of just over 200MW, and around 8000 solar thermal installations.

Of the remaining operational Solar PV, approximately 12,000 of these are community and locally owned PV installations. With around 3500 community and locally owned solar thermal projects, these are typically found across housing associations, public sector, communities and other charitable organisations.

The Scottish Government does not hold this data on commercial or ground mounted only solar PV schemes.

There is approximately 350 MW of solar capacity in pipeline in Scotland, including 32MW in planning, 44MW under construction and 281 awaiting construction, representing 2.25% of the overall renewables pipeline in Scotland. This will take the total capacity of both installed and pipeline of solar in Scotland to in the region of 750MW.

Vehicle Excise Duty is reserved to the UK Government with a proportion of the funds raised allocated to Scotland through the Barnett Formula as part of the block grant. Revenues raised from vehicle excise duty are not hypothecated and are therefore part of the overall Scottish Budget, rather than apportioned to any specific area of spending.

The Fair Work Convention’s Framework defines fair work and underpins our Fair Work policy, but it is not designed to be enforceable. Moreover, employment law is currently reserved to the UK Government, and in the absence of employment powers we continue to deliver our Fair Work Action Plan to embed work practices in workplaces across Scotland.

Through our Fair Work First approach, fair work criteria is being applied to public sector grants, other funding and contracts where it is relevant and proportionate to do so. This approach encourages employers to adopt fair work practices, rather than penalising those who cannot and provides the best opportunity to engage and support employers.

As part of the Bute House Agreement , and subject to limits on devolved competence, by Summer 2022, we will make it a requirement for the recipients of public sector grants to pay at least the real Living Wage and provide appropriate channels for effective workers’ voice, such as trade union recognition. We continue to work with the Fair Work Convention and other key stakeholders to strengthen conditionality and ensure it is proportionate and effective in delivering real benefits.

There has been no specific evaluation of the contribution of solar thermal and solar PV to the heat network targets for 2027 and 2030.

Our Heat in Building Strategy sets out that technologies, such as solar thermal and solar PV, can work well when used in conjunction with primary heating technologies, such as heat pumps.

As set out in our draft Heat Networks Delivery Plan, from the point that the heat networks legislative framework is in place, any new heat network as well as additional plans for heat network extensions will be required to be powered using low and zero emissions sources of heat. The plan also notes that license holders who operate existing networks will be required to prepare and implement a Heat Network Decarbonisation Plan, which will include milestones for making significant reductions in emissions by 2030 and 2035. To support development of these plans, we will commission work to test and develop an approach to preparing them during 2022.

We recognise the importance of energy generated from solar PV in contributing to the decarbonisation of Scotland’s energy supply and contributing to the just transition to a net zero emissions society by 2045.

‎The Scottish Government is currently carrying out a substantial review of permitted development rights (PDR) in Scotland. Through this phased programme, we are taking forward new and extended PDR for a wide range of development types - including solar panels.

We have not assessed the impact that on-site solar generation can have on reducing household energy bills. However, we are currently undertaking research (due to published this year) to examine the extent to which building level storage technologies could help to reduce householder energy costs, when installed alongside zero emission heat technologies. The research, although not specific to solar PV or the savings made by solar PV installations, does take into account pairing solar PV with storage.

We also continue to support microgeneration measures as part of our Heat in Buildings Delivery schemes such as Area Based Schemes, Home Energy Scotland, Warmer Homes Scotland, the Community and Renewable Energy Scheme (CARES) and the Low Carbon Infrastructure Transition Programme (LCITP).

There has been no specific evaluation of the role of rooftop solar and storage in local electrical distribution networks to date. However, in the Bute House Agreement, the Scottish Government committed to set out a vision for the future of solar in Scotland, in consultation with the sector. As we develop this vision over the coming months, we will consider the role of solar in the delivery of a just transition to net zero, including exploring the role that solar technology could play in supporting the decarbonisation of heat and transport, as well as any impacts on local distribution networks.

Also to note, in the Heat in Buildings Strategy, we committed to carry out research to understand the extent to which the deployment of secondary technologies alongside zero emissions heating systems could help to optimise operational performance, minimise energy consumption and reduce end user fuel costs. This research is underway, and seeks to understand the technical feasibility and cost effectiveness of heat batteries, electric batteries, and thermal storage cylinders when installed alongside a range of zero emissions primary heating technologies; both independently of and combined with microgeneration technologies such as solar PV and solar thermal. We expect to publish this research this year.

The Scottish Government recognises that certain inhalers have a particularly harmful impact on the environment. This is an area where rapid change is possible and reducing the environmental impact of inhalers must be a priority.

Hydrofluorocarbons used as propellant in metered dose inhalers prescribed for asthma and chronic obstructive pulmonary disease (COPD) can have a global warming potential of 1430 or 3220 times greater than CO2 depending on the type of gas used.

A draft NHS Scotland Climate Emergency and Sustainability Strategy is out for consultation until 10 th March 2022. This sets out the Scottish Government’s intention to publish an updated Scottish Quality Respiratory Prescribing guide which will focus on minimising patient over-use of inhalers through review and improving patient outcomes, using propellant free options where possible.

Other actions within the draft strategy include encouraging manufacturers to make inhalers with lower emissions and to support inhaler return to pharmacy schemes to help patients dispose of their used inhalers in a more environmentally friendly way.
