What Type Of Solar Panels Should I Install?

Efficiency, cost, and space constraints can all influence the sort of solar panel that is used. The quantity of solar panels you need to install will depend on the efficiency of the various types of solar panels.

When compared to thin film and polycrystalline solar panels, for instance, MonoCrystalline solar panels require less installation space.

Although there are many other kinds of solar panels that can be installed on your roof, MonoCrystalline or polycrystalline solar panels are the most frequently installed panels. Although, due to their superior efficiency, MonoCrystalline solar panels are currently dominating the market for solar panels.


  •  Efficiency rate of 15-20%

  •  They require the least space for installation

  •  Less affected by weather compared to other options


  •  Efficiency rate of 13-17%

  •  Cheaper than MonoCrystalline panels

  •  More temperature tolerant


  •  Most expensive solar panel type

  •  Lower performance at increasing temperatures


  •  Lower efficiency rate compared to MonoCrystalline

  •  More sensitive to high temperatures compared to MonoCrystalline


The most efficient solar panels are MonoCrystalline, with rates between 15% and 20%. This indicates that they can transform 15% to 20% of solar energy into useful energy.

Black silicon solar panels, which are MonoCrystalline panels constructed from silicon with a high purity level, are another reason why this form of solar panel is becoming more and more popular. Because they produce more energy per area than other types, it is also space-efficient. A MonoCrystalline solar panel's surface area will produce 10W more power than a polycrystalline solar panel of the same size.

On the other hand, because of its great efficiency and the superior silicon utilized, MonoCrystalline panels are the most expensive type of solar panel.

A typical UK home uses between 3 and 6 kWh of energy per day, and some UK homes utilize solar energy to power only a portion of their energy needs, which reduces the need for as many solar panels as originally required.


PolyCrystalline solar panels produce more electricity annually than MonoCrystalline ones due to their superior temperature tolerance.

Compared to MonoCrystalline panels, polycrystalline ones are more affordable. Both varieties are constructed of silicon, however while silicon is produced into bars and cut into wafers in MonoCrystalline, silicon is created into polycrystalline wafers by melting many silicon fragments.

PolyCrystalline panels have the drawback of being less efficient due to the less pure silicon used in their construction. An average efficiency rate of 13–17% is to be anticipated.

What Is the Cost Of Solar Panels?

Cost will undoubtedly play a significant role in selecting how many solar panels you require. The size and kind of solar panels are just two of the many variables that affect solar panel prices. For solar panel systems with capacities between 3 kW and 12 kW, prices range from £5,000 to £13,000.

You can find an estimation of prices per solar panel system size in the table below:

Other factors that may affect the cost of solar panels include:

  •  The cost of solar panels in your area

  •  Brand or supplier costs

  •  Labor costs in your area

  •  Site complexities that may require more labor hours

Solar Panel Funding Options

The Smart Export Guarantee (SEG) has the benefit of paying you for the energy you produce, which can ultimately save you money over time. The SEG is a sort of solar panel financing that demands that all exported energy be paid for by your supplier, in contrast to the previous Feed-in Tariff plan.

Do I Need a Solar Battery Storage System?

Your interests will determine whether you install solar battery storage along with your solar panels. Installing solar panels along with solar battery storage is the best choice if you want to avoid energy expenses and lessen your reliance on grid electricity. However, installing solar panels without a solar battery storage may be an option if your goal is to lower your energy costs.

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 environmental friendly

  •  You have reduced or no electricity bills

Homes with solar panels with battery storage consume roughly 80% of the energy they produce, compared to homes without battery storage, which use only 40%.

The quantity of solar panels placed, the size of the solar battery installation, and the capacity of the batteries will all affect how much money you can save by combining solar power with battery storage.

You would need to add more panels and batteries if you wanted to save more energy. A solar expert can give you advice on your options and prices.

How Do I Find the Right Installer?

When done properly, installing solar panels may be a long-term, relatively expensive home improvement project that will pay off in the end.

It's crucial to choose an installation who can guide you toward the best system for your needs and carry out the project efficiently.

PolyCrystalline panels have the drawback of being less efficient due to the less pure silicon used in their construction. An average efficiency rate of 13–17% is to be anticipated.

A background check on the installer is a fantastic idea as well to make sure they are qualified and have a history of satisfied clients.
