Best Solar Panels under $100 and $300

  • Post author:

With the increasing environmental awareness regarding the adverse impacts of conventional energy resources, people are rapidly acknowledging the benefits of renewable energy. Solar energy is considered the most widely developing renewable energy source. Owing to this, the demand for solar energy system components such as solar panels, inverters, generators, etc. is also experiencing a surge. For installing a solar energy system, the first step is deciding what type of panels should be selected. With the increasing technological development, many variants of solar panels are found in the market. Each type of panel has its own set of advantages and limitations so the selection purely depends on consumer requirements. Here we have shortlisted for you some best solar panels under $100 and $300.

Despite the fact that solar energy systems pretty solidly return the initial investment but still the cost element is there while selecting system components. Everyone prefers to buy a product that offers maximum specifications on a low budget. With such a wide variety available as well as increasing government subsidies and tax cut-offs, one can easily buy an affordable panel by doing little research.

Types of solar panel cells

The primary unit of a solar is the “cell”. Solar cells are composed of silicon and absorb photons in the sunlight, allowing them to release electrons from the silicon atom. These electrons are then used for generating electric energy. Solar panels are of three types:

  1. Monocrystalline: These are popular for their higher efficiency and sleeker appearance. They are composed of single-crystal silicon so the generated electrons have room to move. The major limitation is its high cost.
  2. PolycrystallineThey are also known as multi-crystalline solar panels. In these panels, multiple silicon fragments combine to form wafers of the panel, unlike monocrystalline panels. They have lower efficiencies and less cost.
  3. Thin-film technology: This is the most latest technology in solar panels. They are composed of Cadmium Telluride or amorphous Silicon. These panels are very thin and thus have less cost.

Factors to consider when buying solar panels?

Following are some factors that should be kept under consideration while selecting the best solar panels under $100 and $300.

1. Panel cost

This is the most important aspect to consider while selecting solar panels. Cost is determined by multiple factors i.e. size, wattage, service life, certifications, and material quality. However, the least expensive panels might not always provide good efficiency so select the product with the best performance at minimum cost,

2. Panel quality

The quality of materials used to build solar panels is important to consider. Materials vary in their efficiency, durability, and cost. Choose the manufacturer with the highest rating and consumer reviews as you are doing a huge investment. Top-notch manufacturers constantly work on their Research and Development (R&D) which results in regular improvisation in material quality.

3. Energy efficiency

Efficiency refers to the amount of light the panel receives and converts into electricity. It is the measure of the electricity produced by  solar energy systems. Note that higher efficiency comes with a higher cost, therefore, carefully analyze your power demand before paying extra for more efficient panels.

4. Temperature coefficient

It is the measure of the effect of high temperature or heat on the solar panel’s performance after their installation. Solar cells’ type also influences temperature coefficient so choose the right panel which suits your area’s climate. This is important because overheating the panels reduces their life.

5. Size of the panel

This includes both the dimensions of the panel and its power wattage. The size of the panel is based on your electricity requirement and the area available for installation. Select solar panels that are small in size but have high power wattage.
