Technical FAQs 4

Are monocrystalline solar panels a good choice?

Monocrystalline solar panels perform strongly on all key fronts, which is why they’re currently the most popular type of panel. If you go for monocrystalline panels, you’ll be choosing from a collection of the most efficient, powerful, and long-lasting modules on the domestic market.

How much power does a monocrystalline solar panel have?

The best monocrystalline solar panels have power ratings upwards of 500W, with some exceeding 600W and even 700W. In contrast, you’ll struggle to find a polycrystalline panel with a power rating above 400W, and they’ve long fallen around 20% below monocrystalline models, according to data analysts Wood Mackenzie.

What is the difference between monocrystalline and polycrystalline solar cells?

They are generally cheaper than monocrystalline cells and can be used in areas with limited space as they come in smaller sizes. Polycrystalline solar cells are also easier to produce, allowing them to be mass-produced more efficiently. The choice between monocrystalline or polycrystalline solar cells depends on the project and budget.

How much does a monocrystalline solar & battery system cost?

A 4.5kWp monocrystalline solar & battery system usually costs around £11,307, including the price of installation. This should get you 10 solar panels, each with a 450-watt peak power rating, as well as a 5kWh battery.
