Before you purchase solar panels, make sure you read this concise and powerful advisor from Solar Mango, the #1 Solar Guide




A Solar Module is the most important component of a Solar Power System – it is the one that generates electricity and the rest of the system is only to ensure that the electricity thus generated is converted and transported optimally.

Solar Modules account for nearly 50-60% of the total solar power system costs and you are going to live with this investment decision for a very long time – 25 years and more.

SMSA-Cover Page-page-001Given the above fundamental and economic aspects, it is imperative to invest some quality time and effort before purchasing solar modules.

So, what makes the choice of solar panels difficult?

  • When there are more than 1500 module brands available in the market, how will you select the best one optimal for your solar power system?
  • How can you select the right solar module which is an intersection of both good quality and the right price?
  • How would you know that your solar installer’s recommendation for solar modules is the best?

Did you know?

  • PID (Potential Induced Degradation) in solar panels can cause up to 30% performance loss within the first year itself
  • Solar cells in a panel are categorized based on grades. For a high quality panel, the solar cells should be either of grade A or B
  • Nominal Operating Cell Temperature(NOCT) of the panels should be within 47ᵒC to ensure that loss is minimal during high temperatures
  • Solar panels of good quality always have positive power tolerances, which basically means that the generated power will never be below the rated power at standard conditions
  • Sub-components of panels such as backsheet , frame, glass, adhesive, junction boxes, etc., should be sourced from reputed companies
  • The numerous cells in the solar panel should be soldered perfectly to the panel body to avoid burn-outs

And more…

But how does a common man analyse so many technical aspects in a solar panel?

This is where the Solar Module Selection Advisor comes in.

The Solar Module Selection Advisor is written by an unbiased team of Solar Energy Experts from Solar Mango – the #1 Solar Guide. This unique report is published based on extensive research of the technical and practical aspects that are critical to high performing solar panels.

Who is this Advisor for?

The Solar Module Selection Advisor is for those who:

  • Value quality selection for a product with a 25-year old lifetime
  • Keen on having solar panels on their homes
  • Keen on having solar panels on their factories, commercial buildings or institutes
  • Are new to solar but keen on ensuring a high quality solar power plants

What does the Module Selection Advisor offer?

  • Different kind of panel technologies and their applications
  • Simple checklist of critical parameters a quality panel should have
  • An easy methodology to evaluate your solar panel before purchase
  • Case studies on effect of panel quality on solar generation
  • Cost brackets to which panels of different qualities fall
  • Returns vs. Investments for low, medium and high quality panels

From all the above, a non-expert can easily evaluate solar panels and ensure optimal generation from his/her solar power plant.
