Use of solar chargers for cars is both economical since you use the sun which is a free resource and also environment friendly.

    I’m looking for a way to supply power to a cabin in a third world country.
    I would like to buy a car or small truck battery to supply power for two or three 13 watts light bulbs for a few hours nightly and be able to recharge it during the day .
    Do you have a reasonably priced and easy to connect like the Sunsie SE-150 charger that could do the job?

    I am working on building a street-side shredder for unwanted mail items. I want to use a solar panel to charge a 12 volt battery and in turn the 12 volt battery will operate an inverter. The unit will house a (120 v) paper shredder (operated by the inverter) and I want to use the paper shredder once a day for enough time to shred 3-5 pieces of mail. Could you recommend a solar panel, battery size, and inverter for operating my street-side shredder?

    It depends on the charging hours of the battery. I suggst you use 2 batteries one works and the other stay in charge. Actually solar charger may require some hours to fully charge a battery. Consider also your daily energy consumption. Sun should not be a problem where you live :-)
