Simple PV Conversions
Solarising Radio-cassettes, Battery Lamps, Oil Lamps, etc.
Please ask for a pdf/leaflet
The simplest way to solar-convert a radio-cassette is by connecting in the leads from a solar panel to the
battery compartment contacts. The solar panel is best left in a sunny spot with the lead as long as required.
Where local radios are used, this is extremely cheap costing a little as $1 to power a small radio and a little more
for cassettes.
Normally appliances are required to work after dark so we offer special low-cost NiCd/MH or
Li-ion rechargeable batteries for this purpose which are charged up during the day by the
pv panel.
This combination of recells and panel powers radios, torches, mobile phones, lamps, LEDs, etc.
We soon will be offering other alternatives; solarising low cost lamps etc which can be imported direct
from China as well as kits for solar-converting oil lamps!

In recent months we have had a number of requests from developing countries for information about the
solar charging of mobiles (cell phones) .
In Bangladesh, mobiles are hired out in villages so people can contact relations abroad or get vital
The main problem is often charging the mobile where there is no mains electricity.
packs but, for most people, neither is affordable.
You just remove the battery from the phone and fit a simple adaptor connected to a solar panel!
No need for a battery or large panel!
And you can now get cheap mobile batteries so one can be charged from the sun while the other is in use!
Ask us for a leaflet to explain how to overcome mobile charging problems!
Other uses of these PV panels are for charging lead-acid batteries, water pumps, vaccine coolers, etc.
Full details of these techniques and component prices are available by pdf, post or email.
