HOME / how to choose between monocrystalline and polycrystalline panels
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.
A single monocrystalline panel typically costs between $350 and $525 for a 350-watt unit. Pricing varies by manufacturer, efficiency rating, and technology tier. While these panels carry a higher price tag than other types, their performance and longevity often justify the investment.
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.
Monocrystalline solar panels are distinguished by their high efficiency rates, ranging from 15% to 25%. In comparison, polycrystalline solar panels have lower efficiency rates, typically between 13% and 16%. Power Rating: The power rating, quantified in watts (W), is a critical factor affecting the cost of monocrystalline solar panels.
In general, monocrystalline solar panels are more efficient than polycrystalline solar panels because they're cut from a single crystal of silicon, making it easier for the highest amount of electricity to move throughout the panel.
Polycrystalline solar panels have an efficiency of 13% to 16%. This efficiency shows how well the panels are able to turn sunlight into electricity. Polycrystalline panels demonstrate a marginally reduced efficiency when compared to monocrystalline solar panels, which showcase efficiency ratings varying from 15% to 25%.
Monocrystalline solar panels have black-colored solar cells made of a single silicon crystal and usually have a higher efficiency rating. However, these panels often come at a higher price. Polycrystalline solar panels have blue-colored cells made of multiple silicon crystals melted together.
Monocrystalline panels are more efficient, made from a single crystal, while polycrystalline panels are less efficient but cheaper, made from silicon fragments. 2. Which is better for smaller roofs: monocrystalline or polycrystalline panels?
Bui Trung Kien, Deputy General Director of the Ho Chi Minh City Power Corporation (EVNHCMC), cited statistics from before 2021, noting that the city's electricity sector managed over 14,000 rooftop solar systems with a total capacity of about 350 MWp.
In Autumn, tilt panels to 16° facing South for maximum generation. During Winter, adjust your solar panels to a 26° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 5° angle facing South to capture the most solar energy in Ho Chi Minh City, Vietnam.
Vietnam ranks 9th in the world for cumulative solar PV capacity, with 16,660 total MW's of solar PV installed. Each year Vietnam is generating 171 Watts from solar PV per capita (Vietnam ranks 30th in the world for solar PV Watts generated per capita). [source]
Average 5.58kWh/day in Summer. Average 4.92kWh/day in Autumn. Average 5.61kWh/day in Winter. Average 6.26kWh/day in Spring. To maximize your solar PV system's energy output in Ho Chi Minh City, Vietnam (Lat/Long 10.8230989, 106.6296638) throughout the year, you should tilt your panels at an angle of 10° South for fixed panel installations.
