What Determines the Cost of Solar Panels?

Solar Panels Quality and Cost

Top-quality solar panels come with a price premium. So here’s a run-down of solar panel quality and cost:

  • Dubious quality: Brands without a track record. These often produce less power than specified, especially as the years go on. Not worth the risk.
  • Good quality: Good quality solar panels don’t have to be super-expensive. You can also get decent warranty cover at a medium price.
  • Premium quality: These cost around €100 extra per panel and tend to exceed the manufacturers’ specified power generation. They also come with long guarantees backed by household names like Panasonic and LG.

Battery or No Battery?

A battery lets you store solar energy to use at night. The cost is around €1,500-€4,000. Batteries are a good idea for many people, but not everyone.

If you do go for a battery, capacity is key. However, be careful because different manufacturers measure capacity differently. Durability of batteries also varies so choose one made with LG, Samsung, or Panasonic cells.

Inverter Quality and Features

An inverter transforms DC electricity from your solar panels into AC electricity for your house. And like with panels, inverter quality varies. Moreover, inverters have the highest failure rate of any component in solar panel systems. This makes it important to get a good-quality inverter with a strong warranty. In addition, some inverters come with handy features like remote monitoring. The difference in price between a good-quality and poor-quality inverter is around €300-€800.

Solar Panels Installation Workmanship

Good workmanship is key for several reasons. Firstly, correct installation is the start of a long, safe, and productive life for your solar panels. Secondly, good installers will route electrical cables neatly and safely out of the way. Thirdly, they will never take shortcuts on safety. That’s why workmanship is our top priority.

Conclusion: Solar Panels Cost Ireland

Overall, there are three main factors in the cost of solar panels. First is the number of panels. This depends mostly on your electricity use. Second is the quality of the equipment. You should choose good quality equipment. However, you don’t have to get the most expensive panels. This is because there are many good-quality panels for sale at a medium price point. Third is the workmanship of the installers. Workmanship is not worth skimping on.
