What is a Solar Panel?

Solar Panels can generate electricity, heating or hot water for your home however there are 3 different types of solar panels and they all perform different functions.

Types of Solar Panels:

  • Photovoltaic (PV) Solar Panels produce electricity from the sun, which you can then use in your home and/or export to the national grid.
  • Solar Thermal Panels use the suns energy to produce hot water and fill your hot water tank.
  • Thermodynamic Solar Panels are a type of air source heat pump that takes energy from the sun as well as ambient air and provides both heating and hot water.

In this article we will focus on Solar Photovoltaic (PV) Panels.

Solar PV Generation, Savings & Battery Storage

Solar PV panels can save you between 30-50% on your electricity bill however the way you use your home will have an impact on this. If you work from home and use a lot of appliances during the day you will get closer to the 50% figure however if you are rarely home during the day and use appliances in the evenings, you may be closer to the 30% figure.

A solution to increase your electricity savings can be to install battery storage which can save on average an additional 30-40% of the electricity you use however if you do work from home or use appliances during the day a battery may not be a cost-effective solution.

Solar PV Incentives

The Feed-In-Tariff (FiT) scheme provides a financial incentive to installing Solar PV. The Feed-In-Tariff is a payment made to you based on the amount of electricity you generate from your solar panels and is currently (As of January 2019) 3.79p/kwh for a 0-10kW system.

The Export Tariff is a financial payment made to you for any excess electricity you generate that is sent back to the national grid and is currently (As of January 2019) 5.24p/kwh.

The Feed-In-Tariff and Export Tariff will come to a close at the end of March 2019 however a new scheme will takes its place called the “Smart Export Guarantee” which will require all large energy suppliers to provide payment for all electricity that is exported to the grid.

Solar PV Costs

A typical PV system of 4kW (14-16 Panels) costs between £4,500-£6,500 and the costs vary based on:

  • Type of Panels (Mono or Poly)
  • Type of Installation (On-Roof or In-Roof)
  • Type of Scaffolding required
  • Type of Inverter selected
  • Micro Inverter
