How PV solar panels work
  • Sunlight hits the solar cells in the panel
  • The sunlight knocks electrons loose from the atoms of the semiconductor material
  • These electrons flow through the cell, creating an electric current
  • The electric current passes through an inverter, which converts it into AC electricity
  • The AC electricity can then be used to power your home or business

FAQs

You must have a few questions. Here’s the answer to a couple of the most frequently asked ones relating to solar panels and solar panel grants, but if you have any more, we’d be happy to help.

How are solar panels installed?

In Cardiff, solar panels are usually installed on roofs, but they can also be placed in areas like carports or ground mounts. The process typically involves:

  • Site Evaluation – Assessing your property for solar panel compatibility.
  • Scaffolding and Roof Preparation – Ensuring safe roof access.
  • Mounting System Installation – Setting up a secure mounting system for the panels.
  • Solar Panel Setup – Carefully attaching the panels to the system.
  • Electrical Connection – Linking panels to an inverter to convert solar energy into home power.
  • Final Inspection and Testing – Checking system efficiency and operation post-installation.

How long does a solar PV installation take?

In Cardiff, the time for a solar PV installation can vary, but it’s generally completed in one to two days.

Is my roof suitable for solar panels?

To assess if your Cardiff roof is suitable for solar panels, consider:

  • Roof Size – Determines panel quantity.
  • Roof Orientation – South-facing is ideal.
  • Roof Type – Compatibility with solar panels.
  • Roof Condition – Must be robust to support panels.

Unsure about your roof’s suitability? Our team is here to help.

Do I need planning permission for solar panels?

Typically, in Cardiff, solar panels don’t require planning permission, except for listed buildings, conservation areas, or systems with significant height or visibility.

How many solar panels do you need to run a normal house?

According to studies performed by Ofgem and OVO Energy, the average UK household uses between 56 and 72 kWh of electricity each week. To put that into some kind of context, a one-bed flat would need approximately 6 solar panels, while an average 3-bed home would need 10 panels.

Are solar panels enough to power a house?

Definitely! However, the number of solar panels you’ll need will depend on the size of your home, the type of roof you have, the direction your home faces, and your energy usage. For example, if you have a small home and don’t use a lot of electricity, you may be able to power your entire home with solar panels, but if you have a large home or use a lot of electricity, you may need to supplement your solar panels with energy from the national grid.

How much do I get for selling electricity back to the grid in the UK?

This depends on the Smart Export Guarantee (SEG) tariff that you’re on. The SEG tariff is set by your energy supplier, and the rates can vary. However, the average SEG tariff in the UK is around 4.5p per kWh, meaning that for every kWh of electricity that you export to the grid, you’ll be paid 4.5p. If you’re considering installing a solar energy system with a view to selling energy back to the National Grid, speak to one of our expert advisors, who can give you a better idea of the sort of setup that you’ll need.
