What Are The Best Solar Panels For Your Home & Business?

Solar panels have become part of the planet’s world and energy revolution. Solar energy allows us to be energy independent and save money by breaking free from power companies. By using this renewable energy source, we are also helping the planet and ensuring that we rely on an inexhaustible energy source.

Progress in technology has made it possible that even if there are cloudy days, we can store enough power to continue using it in our daily tasks.

But to take advantage of solar energy, we must use solar panels and, to get the maximum efficiency when collecting the energy from the sun, we have to choose the right solar panels, as there is no one-size-fits-all.

What to look for in a solar panel?

Hundreds of different brands and models of solar panels are on the market. So, to make the right decision, you have to pay attention and consider a few things. Here’s what to look for:

Solar Panel Size

One of the essential elements to look at and take into account is the size of the solar panels.

I always recommend a detailed assessment of how we want to place the panels before any installation. This will help to find out what space is available, what space we want to occupy with them, and the efficiency and type of panel required.

Type of Solar Panels

We already cover this in our previous article, “Solar Panels: The Ultimate Guide to Get the Right Solar System for your Home“, but I’ll leave here a quick overview:

Monocrystalline or Polycrystalline Solar Panels?

Monocrystralline Solar Panels: Monocrystalline panels are still the most expensive option but also the most effective for generating electricity from solar energy. Its efficiency ranges from 18% to 22%.
Polycrystalline Solar Panels: Polycrystalline cells are characterized by a high quality-price ratio: their efficiency ranges from 14 to 18%, thanks to which they effectively convert energy.

How do I differentiate Monocrystalline and Polycrystalline Solar Panels?

Monocrystalline solar panels are darker in colour, often black or dark grey, while polycrystalline solar panels have a dark blue colour when exposed to light.

In the table below, you can see a quick comparison of the advantages and disadvantages of polycrystalline and monocrystalline solar panels:

Panel Type

Advantages

Disadvantages

Monocrystalline

• High efficiency

• Space efficient

• Have a long lifespan

• More efficient in warm weather

• Higher Cost

• Less sustainable

Polycrystalline

• Easier production

• Lower cost

• Efficiency of panels

• Lower space-efficiency

If you have a lot of space for solar panels, you could save money upfront by installing low-efficiency, low-cost polycrystalline panels. However, roofs with limited space might require installing high-efficiency, monocrystalline solar panels.

It’s always best to consult a Solar expert who can advise you.

Nominal Voltage

For isolated solar installations with batteries, the panels are 36 cells (12 V) or 72 cells (24V). If we want to use the module in a small isolated installation that feeds a battery (monoblock, for example), we will need 12V panels, while if our installation is a little larger and has a larger accumulation system (two monoblock batteries), we will need 24V panels.

Nominal voltage is not usually found on the product data-sheet; instead, they usually put the voltage at maximum power. The nominal voltage is the closest to the standard’s maximum power (12-24-48 Volts).

Power of Solar Panels

Solar panels differ according to their maximum working power Wp (peak watt), which means the maximum power it can reach.

How to choose the right power for your solar panel?

First, you must calculate the power that your appliances consume. Multiply the power in watts (W) of your appliance per the time (hours) of use over one day. Example: A 50 Watt television turned on for 3 hours daily consumes 50 x 3 = 150 Wattheure (WH) daily. If you have several pieces of equipment, repeat the operation and add the total (WH).
Once we know exactly our consumption, we need to know the power necessary to satisfy this consumption. For this, we need to take into account some factors, such as:

- The power generated by the solar panel
- Solar Panel efficiency
- Number of hours of sun

Once we have this data, we can use the following formula to determine the actual power generated per hour for each photovoltaic panel:

**(Solar Panel Power * System Efficiency * Hours of solar exposure) / 1000 = KWh Generated per Day**

Your solar panel must produce enough energy on a daily basis to supply your electrical appliances.

Efficiency of Solar Panels

We call efficiency to the power that the panel is capable of producing 1 square meter of photovoltaic solar panel when it receives an irradiation of 1000 W / m2.

For example, If in the technical data sheet of a 245W photovoltaic solar panel we see that it has an efficiency of 15%, it means that for every 1000W / m2 of irradiation that 1 square meter of panel receives, it will produce 150 W of power.

Nowadays it is quite common to extol the quality of the higher efficiency solar panels, and many times, the higher efficiency solar panels are considerably more expensive.

In my opinion, if we don’t have space problems, it doesn’t make much sense to pay a higher price for more efficient solar modules. On the other hand, if we have a very “fair” roof, we can install more efficient solar panels to optimise the installation as much as possible.

Top Solar Panel Brands On the Market

Now let’s have a look at some of our top favourite brands of solar panels. We will present some of their top solar panels and their characteristics so you can choose the one that is right for you.

Canadian Solar

Canadian Solar Inc. is a Canadian and Chinese company dedicated to manufacturing solar energy products that manufacture solar modules and photovoltaic solar energy systems.

Canadian Solar, founded in 2001, is already one of the five largest producers of solar panels in the world in terms of global production, both for large solar orchard areas and for residential and industrial photovoltaic self-consumption installations.

Its products include modules, inverters and complete kits with all the necessary systems for producing solar energy.

Canadian Solar panels have to pass a triple security check. In addition, they ensure that their solar panels are durable and 100% recyclable.

REC

REC is a pioneering multinational solar energy company founded in 1996 in Norway. At the end of 2019, it already operated around 38 million solar panels that accumulated more than 10GW of clean energy: Enough to power the homes of 16 million people. It is one of the largest suppliers of solar panels worldwide, specialising in commercial and industrial installations and residential use.

Its latest advances for improving its solar panels have focused on seeking to prevent the loss of power, taking into account any adverse weather situation, such as environments with a very high temperature or very high humidity: 100% free of induced power degradation.

How we determined the best solar panels in Australia

These are some of the largest solar panel companies in the world. The most important thing to take into account when buying a solar panel is the power we need according to the use that we are going to make of the solar panels. Likewise, it is interesting to see if the company has a service to facilitate the transfer of the panels or if you have to transport it yourself. Also, look at the modulated efficiency of the panels and the temperature they support. Finally, take into account the years of energy guarantee that they promise.

I hope this guide has been of help, and don’t hesitate to contact us if you have any questions.
