Curious about how much you can save on electricity bills with solar as a Homeowner in Wales?

Solar for home

Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source. It can be harnessed in all areas of the world and is available every day. We  cannot run out of solar energy, unlike some of the other sources of energy. Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years when according to scientists the sun is going to die.

Reducing Electricity Bills

Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop.
How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage.
For example, if you are a business using commercial solar panels this switch can have huge benefits because the large system size can cover large chunks of your energy bills.
Moreover, not only will you be saving on the electricity bill, but there is also a possibility to receive payments for the surplus energy that you export back to the grid through the:-
Smart Export Guarantee (SEG).
If you generate more electricity than you use (considering that your solar panel system is connected to the grid).

Solar powered home
Available solar panels

Monocrystalline solar panels have the highest efficiency rate of 15 – 20%. This means that they can convert between 15% and 20% of sun energy into usable energy. This type of solar panel is also space efficient because they generate more energy per area compared to other types. One square metre of a monocrystalline panel will generate 10W more than the same size of a polycrystalline solar panel.On the other hand, monocrystalline panels are the most expensive solar panel type due to their high efficiency and quality of silicon used.

Features Included

Efficiency rate of 15-20%

The more expensive solar panel type

They require the least space for installation

Less affected by weather compared to other options


Due to their high temperature tolerance, polycrystalline solar panels generate more electricity over the year compared to monocrystalline panels.
Polycrystalline panels are a cheaper alternative to its monocrystalline variant. Although both types are made from silicon, in polycrystalline, many fragments of silicon are melted to form the wafers for the panel.
While in monocrystalline silicon is formed into bars and cut into wafers. A downside of polycrystalline panels is that they are less efficient because their silicon material is less pure. You can expect an average efficiency rate between 13-17%

Features Included

Efficiency rate of 13-17%

Cheaper than monocrystalline panels

More sensitive to high temperatures compared to monocrystalline

Do I Need a Solar Battery Storage System?

If you would like to avoid electricity bills and reduce reliance on grid power, then installing your solar panels with a solar battery storage is the most appropriate option. However, if your initial goal is to just reduce your electricity energy bills then installing solar battery storage at a later date is also a good decision based upon known factual home electricity consumption and surplus solar exported results

A solar battery storage has several benefits
  • You can store the unused energy generated by your solar panels
  • You will be less reliant on the grid electricity
  • You will be more environmentally friendly
  • You have reduced or possibly no electricity bills

Households that install solar panels with a battery storage, use about 80/90% of the energy they generate while households without a battery storage use circa 50% of energy they generate.

The amount of money you can  save  by installing your solar panels with a solar battery storage depends on the number of solar panels installed, the  size of solar battery  installation, and how much the batteries can discharge.

As solar professionals we can advise you on different options and costs.
