Polycrystalline Solar Panel Review

Are polycrystalline solar panels a good choice?

Polycrystalline solar panels are generally more affordable than their monocrystalline counterparts, making them an attractive option for budget-conscious consumers. They're a reliable energy source, although less efficient than their monocrystalline counterparts.

What's the difference between monocrystalline and polycrystalline solar panels?

The difference between the two main types of solar panels installed today, monocrystalline and polycrystalline, starts with how they're made, a difference that affects how they perform, how long they last and how they look on your roof, said Rohit Kalyanpur, CEO of Optivolt, a Silicon Valley-based solar technology company.

Are monocrystalline solar panels efficient?

Efficiency ratings of monocrystalline solar panels range from 17% to 22%, earning them the title of the most efficient solar panel type. The higher efficiency rating of monocrystalline panels makes them ideal for homes with limited roof space, as you’ll need fewer panels to generate the electricity you need.

What are the pros and cons of polycrystalline solar panels?

To fully appreciate the pros and cons of polycrystalline solar panels, it’s helpful to stack them up against other kinds available in the market. While both types are made of silicon, monocrystalline panels are crafted from a single, pure crystal structure, allowing electricity to flow easier, which leads to a higher efficiency rate.

How much does a monocrystalline solar panel cost?

On average, monocrystalline solar panels cost £350 per square metre (m²), or £703 to buy and install a 350-watt (W) panel. Polycrystalline panels, on the other hand, cost around £280 per m², or £562 for a 350 W panel. This is partly because producing single-crystal silicon – used in monocrystalline panels – is a long, complicated process.

How much power does a monocrystalline solar panel produce?

Most monocrystalline panels on the market today will have a power output rating of at least 320 watts, but can go up to around 375 watts or higher! Polycrystalline panel efficiency ratings will typically range from 15% to 17%. The lower efficiency ratings are due to how electrons move through the solar cell.
