How many types of solar panels?

For many people, there might be some confusion, as quite a few might not know that there are different types of solar panels. Their lifespan and advantages also vary. Today, let’s get to know solar panels better. Currently, many individuals and businesses are looking for alternative energy sources to reduce electricity costs and to help conserve energy. One interesting option that seems suitable for our country is solar energy. In this article, SE will introduce the types of solar panels and the factors to consider before installing a solar panel system.

What is a solar panel?

A solar panel is essentially a collection of many solar cells connected together to form a large panel, which increases the efficiency of electricity production and distribution. The electricity generated is direct current (DC), but the appliances in our homes use alternating current (AC). Therefore, an inverter is required to convert the DC electricity to AC before it can be used in the home. [Read more about DC/AC]

How many types of panels are there?

Divided into 3 types:

1. Thin Film Solar Cell

It will be thinner than other types and the color will be darker.

Advantages:

• Affordable
• Lightweight
• Good heat resistance

Disadvantages:

• Low electricity production
• Short lifespan

2. Mono Crytalline Solar Cells

It is a panel made from cylindrical silicon with a dark color. The four corners are chamfered squares.

Advantages:

• Longest lifespan
• Efficient electricity production even with low sunlight
• Compact size, suitable for installation in limited spaces like rooftops

Disadvantages:

• High cost
• If not cleaned regularly, it can cause the inverter system to overheat and potentially burn out

3. Poly Crytalline Silicon Solar Cell

This is a panel made from cylindrical silicon, with a dark color and no chamfered corners. The panel appears in a dark blue hue. It operates at higher temperatures compared to small crystalline panels, but has a shorter lifespan than mono panels.

Things to consider before installation:

1. Before installation, it’s crucial to thoroughly assess the strength of your roof and the direction for installation
2. To determine the appropriate size of a solar panel system based on your electricity usage, you should check your past electricity consumption. This can typically be done by reviewing your utility bills or accessing usage records provided by your electricity provider. By understanding how much electricity you have been using over a period of time, you can estimate the size of the solar panel system needed to meet your needs effectively.
3. Choosing a solar panel service provider is crucial, given the wide array of options available in the market. It’s essential to opt for a provider with both pre- and post-sales experience and standards, including warranties. Of particular importance is ensuring the equipment used meets genuine standards. Some providers may also assist with permitting for grid-connected or regional power grid applications, which can involve complex paperwork and procedures.

Installing a solar panel system may appear to be a relatively high initial investment, but it is undoubtedly a worthwhile long-term investment. Paying upfront allows you to use the system for over 25 years if well maintained. Besides saving money in the long run, it also contributes positively to the environment. For those considering or deciding on a service provider, you now have a basic understanding of the types of panels and factors to consider before installation. This helps ensure optimal efficiency and maximum benefits from your solar system.
