This highly efficient 30W SunPower SPR-30 solar panel is made up of monocrystalline silicon cells and delivers 30 Watts to charge up the batteries connected to your electrical device.
The SunPower SPR-30 is an ideal solar panel for people who need a compact solar panel that provides enough power to operate a range of low-mid range electrical devices such as an electric fence system, basic lighting, radios, etc. The SPR30 is an ideal way to start in solar energy and is ideal for use when you are away in the caravan, installing a garden lighting system or simply a reliable power source away from the mains grid.
SunPower SPR-30s solar cells produce high voltage per cell with an extremely low voltage-temperature coefficient; this enables effective battery charging performance at high operating temperatures. Add exellent low-light performance and a broad spectral response and you have a solar panel that can deliver energy all year and in most weather conditions.
To protect your batteries from overcharging we recommend incorporating a suitable charge controller, such as the Sundaya Apple 10A to your system.
This solar panel is 'Power guaranteed' for 25 years.
The SunPower SPR-30 is also available as a complete kit: Solar Panel Kit 12V/30W

Installation Basics: SunPower solar panels are not supplied as standard with any mounting brackets or cables other than the industry standard connections for “national grid installations”. This is because even though solar panels are relatively simple to install, virtually every installation is a bespoke project with unique requirements. Most end user customers and installers prefer to source their own cables and brackets based on these specific requirements.
For connections to a battery, or battery-bank you will require “Twin Sheathed (Double Insulated) 2 Core Cable for the connections from your panel/s to the charge controller and then to the battery/ies. The cable must be rated to the required amperage for your installation and is available from any good local electrical/DIY retailer.
Likewise, the means of securing your solar panel in position are as many and varied as the applications for which solar panels can be used. For boat, caravan,
motor home user it can be as simple as using a professional strength adhesive such as Sikaflex (available from any good Chandlery – but remember that if
you do, you will have to sell the solar panel with your boat etc. as it’s there to stay!). For walls, tiled roofs, sheds, poles etc you will need to buy/create different means of fixing.
