RS PRO 45wp Solar Panel Kit Bulk Pack

The 45wp Solar Panel Kit is Ideal for use in caravans where the time spent away from a mains hook up is no more than 4 days. Also useful for charging consumer appliances such as mobile phones, electric toothbrushes, digital cameras, powering electric gates, garden pond pumps or TV’s. The 45 watt panel provides a continuous trickle feed maintaining and extending the life of any 12 volt battery.

This kit is great for small power consumption projects and perfect for use in boats and caravans during weekend trips. The 45-watt solar panel kit can even be used for projects as diverse as powering electric fences or charging small power tools. The 45-watt panel provides a continuous trickle feed, maintaining and extending the life of any 12-volt battery when used in conjunction with a charge controller.

The 10Ah (STCC10) (RS 905-4532) Charge controller (sold separately) should be used with this kit to protect the battery from being overcharged and to prevent reverse current drain

Features and Benefits

• High efficiency crystalline cell for “all weather” charging

• Perfect for powering colour pond pumps / fountains* and for use in larger caravans over a week’s period

• Water resistant, robust construction for outdoor use.

• 10 year module warranty***

Applications

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.

What is the best way to install solar panel systems?

• Installing solar panels at a 55-65° angle increases optimal wintertime performance.

• For a year-round power supply, solar panels can be combined with wind chargers.

• Solar systems 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.

• Do solar panels work on cloudy days?

• To optimize solar energy generation, solar power panels and charging implements work most effectively in direct sunlight. They can still charge on cloudy days, though it will not provide as much power.
