What are Solar Panels?

Solar panels, also known as PV panels convert the energy particles from sunlight called photons to electricity. This electricity can be utilized for different applications such as powering the equipments in your home or business, street lights, water pumps, etc.

What Are the Different Types of Solar Panels?

Monocrystalline and polycrystalline solar panels are the most widely used solar panels.

What You Should Choose- Mono VS Poly

  • Monocrystalline Solar Panels

These solar panels are made of thin silicon wafers. They are known as monocrystalline as they are made from large single crystals that are developed in controlled conditions. They are 20% more efficient than the other panels available. However, the production cost is comparatively higher than the rest.

Advantages

Energy and space-efficient

  • Performs better than polycrystalline panels irrespective of low-light conditions

Polycrystalline Solar Panels

Unlike monocrystalline solar panels, polycrystalline panels are created by pouring molten silicon in a cast. This makes it a cheaper alternative.

Advantages
  • Cost-efficient
  • Simple manufacturing process

How long is the warranty on Solar panels?

Solar Panel warranty has two parts – product /equipment warranty and performance guarantee. The equipment warranty will protect you against any manufacturing defects, durability issues or failure of the product. Most brands offer a warranty of 10-15 years, while some premium brand offer 25 years of equipment warranty.

The performance guarantee ensures the panel produces a base energy over the lifetime of the panel. The amount of electricity the panel produces slightly declines every year they are in use. However, this decline should not be more than 10-20% over 25 years.
