4 man boat £21
6v 100AH £28ea
Solar cells and chargers from bull electrical
Solar regulators 12v, up to 135 watts peak
We offer two solar regulators to use with the above panels, both offer overcharging and inverse current protection.
our new 12v solar panel
10 watt silicon solar panel, at least 10 year life, 365x26mm, waterproof, ideal for fixing to caravan roofs, boat, motorhomes etc. Very nicely made unit with hidden fixing holes for secure fitting. Complete with leads and connectors. Aodized aluminium frame.
Each panel is supplied with two leads, one lead is used for the output and is 3m long with two large crocodile clips, the other lead is used to connect extra panels if required.
Note: These panels do NOT require a blocking diode, they can be left connected at all times without discharging the battery.
Special offer 1 panel and 1 regulator save £10
4 panels and 1 regulator save £20
New Universal Solar charger will charge 2 batteries at once
Large built in solar panel approx 6" x2" provides enough power to recharge nicad batteries.
Hinged lid and adjustable foot.
Perfect for many 12v DC uses, ranging from solar fountains to hydroponics!
Small and compact yet powerful. Will work direct from our 14 watt solar panel in direct sunlight. Max head:l7 ft Max flow rate : 8 1pm Current :1 .5A

Renewable energy CD rom, reports, articles, magazine reprints, photovoltaics, wind, hydro,EV's,biofuels,heatpumps, geothermal, energy conservation, wind, water etc. Hundreds of articles, plans, illustrations etc. Excellent value
Solar panel experimenters kits ( proper ones!)
400mA solar panel (plastic) low inertia DC motor, lead, fan, turntable discs, instruction booklet.
Advanced solar energy kit
Contains 8 solar panels plus connecting strips, motor etc. Ideal for experiments with current/voltage series parallel wiring etc.
Encapsulated solar panels with an output of .45v. Three sizes available with different current outputs.
SOLAR POWERED WIND UP RADIOS
This radio has a built in hand operated battery charger, built in rechargeable batteries and and a built in solar panel so it should always work!
Regulators protect batteries from overcharging. On reaching capacity the regulator diverts excess power into heat thus preventing battery or equipment damage. Maximum power is 60 watt.
High power dc to dc modules
suitable for wind/solar generators

SOLAR NICAD BATTERY CHARGERS
The perfect way to keep your personal stereo batteries charged up
Just put in your rechargeable batteries and leave in the sun! Two types available
4 x AA size
2 x C size
Differential thermostat kit
If you are building your own solar system you could use one of our kits for controlling it. The kit contains to sensors, one you place on the solar panel, the other on the tank. When there is a temperature difference between the sensors (this is adjustable on the pcb) a relay operates. This could turn a pump on until the temperatures were back below the pre-set temperature difference.
