Solar Panels in Wales

More homes in Wales are turning to solar panels as their primary source of electricity. Solar panels in Wales are one of the most popular renewable energy sources.

While the initial costs can be quite high, the return on investment is worth it. Solar panels also help lower your energy bills and reduce your carbon footprint in the long run.

Solar panels are a great investment because they can cut your heating costs by up to 78% over 15 years. Moreover, you can save £1,000 by producing solar energy each year.

A solar PV system provides power to your home, business, or farm. They generate renewable electricity after exposure to sunlight and are stored in solar batteries or PV cells. You can then use the electricity directly in your home.

Why Choose Solar Panels?

Solar panels reduce your carbon footprint and as more and more householders become environmentally conscious this is an important consideration.

As the cost of energy continues to skyrocket it makes more sense to install solar panels to your residence.

How Solar Panel Works as a Renewable Energy Source

Solar panels use the sun's energy to generate electricity. They convert light into electricity and create a current in their wires. The amount of sunlight you receive depends on where you live in Wales. Depending on location and season, it can range from 18-30 kW/m2.

The first step in using a solar panel is identifying what kind of system best suits your needs: grid-connected (in which energy is fed directly into the grid), off-grid, or hybrid (using both grid connection and self-generation).

Installing a Solar Panel in Wales

The first thing you need to do is find the best place for your solar panel system. You can do this by talking with one of our local energy experts about the best places to install solar panels.

How Much Does a Solar Panel Installation Cost?

The cost of installing solar panels depends on a variety of factors. The size of your system, what you need to do to your roof, and the type of panels you choose can all add up to make it more expensive than other options.

A standard 250W solar PV system in Wales can cost you from £400-£500. However, the price varies depending on several factors.

Depending on the system size, the number of panels, and roof space the cost of installing solar panels in Wales can vary. For a more accurate quote please contact our team.

The solar industry has introduced Energy Efficiency and Renewables Awards for the companies that produce the best solar panel systems. There is also a scheme of solar funding by the government for people who can't afford the cost of solar panels.

Types of Solar Panels Wales

There are two main types of solar panels available in Wales:

Polycrystalline Solar Cells

These cells are stacked in thin layers (called 'pixels'). The topmost pixel absorbs the light and transfers it to another with a lower wattage rating, which converts it into electricity.

This type has a higher output than monocrystalline cells but generates more heat while operating at full power. It means you can only use them in places with plenty of air circulation around them or nearby structures that are not exposed directly to direct sunlight for long periods.

Monocrystalline Solar Panels

These solar panels use a single crystal material instead of multiple pixels like polycrystalline ones. It makes them much thinner than their counterpart but also less efficient at converting sunlight into electricity due to increased losses because of imperfections within these materials themselves (including scratches).

They're suitable for hot climates with little airflow around them. The heat build-up will not affect performance negatively as long as temperatures remain below certain limits.

Benefits of Solar Panels Wales

Cost-Effective Renewable Energy

Firstly, they're affordable compared with other forms of renewable energy, such as wind turbines or hydroelectric dams. One small system may cost just a few hundred pounds a month. In comparison, larger ones will cost around £500 per month.


In addition to being cheaper than conventional forms of energy production like oil or coal-fired power plants, they produce no pollution during operation.

Sell Excess Electricity

You can generate free electricity, get paid for the electricity you produce, and then sell the excess to the national grid. The Smart Export Guarantee (SEG) tariff provides policies and payments for excess solar power.


Solar panels in Wales are becoming more accessible to everyone so that more people can use them. Buying solar panels is more accessible than before, and you can even choose what type you want. At Hafod Renewables we can help you with everything from the initial quote to ongoing support and maintenance of your PV cells.
