The electricity that is supplied to your home is generated by burning fossil fuels. This is increasing greenhouse gases and leading to global warming. Over the years, the detrimental effect of this practice has been – global warming.

However, the advances in science and technology have enabled you to move towards greener power sources like solar energy. Solar energy represents clean and green energy that is sustainable and abundant. It does not release any greenhouse gases and helps reduce your carbon footprint.

If you are environmentally conscious and want to make a difference by changing your lifestyle choices, then install a solar power system in your home. Buy the best 300-watt solar pane, and you are sorted.

But if you are pondering which solar panel is good and what factors to look for in a good solar panel, then scroll below.

1. Performance

Performance is one of the most important factors to consider before buying solar panels. You need to ensure the solar panels can seamlessly generate power when the sun is shining. A bright sunny day means that solar panels are generating enough electricity for your needs.

According to solar panel experts, the average power efficiency of solar panels is around 15 to 22%. So, it would be best to look for solar panels that offer an average or higher power efficiency.

2. Type of Panel

Thanks to innovations in solar technology, you have varied options when selecting the best 300-watt solar panel. Typically, there are three types of solar panels available – thin-film, monocrystalline, and polycrystalline.

  • Thin-film – it is the latest type of lightweight and affordable panel. It gives flexibility during installation. But, its power output is not as good as the other two mentioned in this list.
  • Monocrystalline – it is the oldest type of solar panel but the technology has developed in recent years. Though they are the most expensive of the three types, they are also the most power-efficient.
  • Polycrystalline– it is a relatively new type of solar panel that is gaining popularity amongst customers. Its power efficiency is slightly lower than monocrystalline solar panels, but their cheaper price tag makes them an attractive investment.

3. Panel Size

Your roof might have ample space, but it might not be economically feasible to cover all the roof space with solar panels. Therefore, you need to calculate power output requirements and the roof space to determine the correct panel size.

The solar panel’s energy output is calculated by energy per square meter. It can help you decide the number of solar panels and the right size for the solar power system configuration setup.

4. Roof Compatibility and Mounting

The placement of solar panels plays a vital role in harnessing solar energy. You need to install them at a place where there are no trees, buildings, or structures. Solar panels need unobstructed sunlight to function.

Secondly, the solar panels should have a good quality mounting system to keep them sturdy and stable even on a windy day.

5. Durability and Warranty

Solar panels are devices that are installed outside. So besides sunshine, the panels are exposed to harsh weather elements as well. Hence, durability is an essential aspect to consider before making a purchase. It would help if you avoided low-quality solar panels that easily break. Saving a little during purchase time and then spending over maintenance will impact your power savings. Therefore, enquire about the durability factor of the solar panels and different tests that the manufacturer has conducted about durability and efficiency. Also, make sure that there is a warranty backing the product. This would ensure that you can get them replaced if there is a sudden malfunction in the warranty period.

So, these are the five factors that you must consider when buying the best solar panels.
