  •  Your house is costly to heat and uses a lot of electricity.
  • You or your cohabitant(s) receive a means-tested benefit or have a long-term medical, mental, or respiratory illness with an annual income below the designated limits.
  1.     Smart Export Guarantee (SEG)

Energy suppliers reward homeowners who generate their renewable electricity—for example, through solar or wind turbines—with an export tariff under the SEG.

Anyone installing solar panels with a capacity of up to 5kW is eligible for the SEG. In addition, they need to have an export metre installed and hold a certificate from the Microgeneration Certification Scheme (MCS) or an equivalent. While adding a solar storage battery to the system isn't necessary to qualify for SEG funding, it could help avoid the wastage of any extra energy.

  1.     Zero VAT

The usual rate of Value Added Tax (VAT) in the UK is 20% for the majority of products and services. Nonetheless, under government incentives, energy-saving supplies and machinery, such as the best solar panels, are eligible for a lower VAT rate.

The current lower rate is zero percent, and it will stay that way until March 31, 2027. It covers the installation of solar panels in homes located in Wales, Scotland, and England.

How to Install Solar Panels?

Installing solar panels involves a series of steps to ensure optimal performance and longevity. While it is recommended to hire a professional installer, understanding the basic process is essential. Here is an overview of the typical steps involved in solar panel installation:

Site Assessment: A professional installer will assess the site to determine its suitability for solar panels. Factors such as roof orientation, shading, and structural integrity are considered during this phase.
