BP Solar 4.5W Polycrystalline solar panel

The performance of these solar panels is optimised for daylight using high efficiency silicon nitride multicrystalline silicon cells bonded to a tough Tedlar™ backsheet. The BP Solar aluminium edge frame is 5cm deep on all panels from 10W, providing a better than average rigidity thus reducing flex in high winds and protecting the glass. The tempered high transmission glass withstands a 1” hailstone at over 50mph and features anti-reflective SIN™ coating for self-cleaning. BP Solar is a world leading developer and manufacturer of solar panels offering performance warranties up to 25 years.

All BP Solar panels have a rugged junction box with large terminals for electrical connection except for the 4·5 Watt panel which is supplied with a 3m integral lead.

System Voltage 50 volts

Solar Panels and Chargers

Solar “photovoltaic” panels use the power of the sun to generate electricity and can be used in a variety of applications from calculators to homes. They are most effective, versatile and cost saving in many commercial and leisure applications for charging 12/24V batteries.
Solar panels provide power through batteries at off grid and isolated locations and are widely used in critical telecommunications and telemetry applications. Solar panels enable rapid installation of equipment at remote sites, either temporary or permanent, avoiding the costs and inconvenience of grid connection. They are designed for very low maintenance and longevity.

How Much power?

The daily power production of a solar panel can be calculated by multiplying the panel’s peak power rating by between 0.5 and 6 depending on the time of year, angle and location. For example; an 80Watt solar panel produces a peak current of 4.55A.

Solar Installation

Solar panels are usually installed at a 55-65° angle for optimal wintertime performance. For a year round power supply solar panels can be combined with Wind chargers.
Solar panels can be connected in parallel to increase power and in series to increase voltage.
To complete the system deep cycle batteries, a voltage regulator and electrical cables are required to get up and running. A range of convenient mounting kits are available for pole or wall mounting.
