Solar Panel 40w | 12V/18V | Monocrystalline | Dimension: 520x520x20mm | Module Efficiency: 14.79%
Prostar 40w solar panel is made with monocrystalline silicon solar cells, which are easily recognizable by the even dark coloring of the cells. Monocrystalline solar cells are made out of silicon ingots, which are cylindrical in shape. To optimize performance and lower costs of a single monocrystalline solar cell, four sides are cut out of the cylindrical ingots to make silicon wafers, which is what gives monocrystalline solar panels their characteristic look.
These solar modules are designed to be 18 voltage, suitable to charge 12 voltage battery or power 12 voltage DC load, like solar street lights.
Solar panels refer either to a photovoltaic module, a solar hot water panel, or to a set of solar photovoltaic (PV) modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells.
Monocrystalline 40w solar panel uses the latest innovative cell technology, increasing module power output and system reliability, ensured by 20 years of experience in module manufacturing, well-engineered module design, stringent BOM quality testing, an automated manufacturing process and 100% EL testing.
The small size of the Prostar 40w solar panel makes it perfect to take with you and for small solar projects! You’ll have no problem using this panel to charge your favorite small electronics while on-the-go.Prostar 40W monocrystalline panel will give you the most efficiency per space.
Prostar 40w solar panel monocrystalline can also perform better in higher temperatures and shady conditions, though there will only be marginal efficiency differences. Paying a higher upfront price for monocrystalline panels might also make the most economic sense in the long run if you buy your system as opposed to leasing it. With a higher efficiency and more energy generated, you might see a greater return on your investment in the form of lower energy bills.
