E & B Discount Marine (one of the big catalogs) lists a >"high output" solar panel which develops 5 W (presumably this means in bright >sunlight) for $98.95. Not very cost effective. Checking out marine and RV places is not the best way to find out about solar panel prices. These places are very expensive (they cater for people with more money than they need, ie recreational activities). If you want to get realistic prices, call Solarex. They manufacture and distribute solar panels world wide. The panels are made from marine grade materials and are designed for real world use, i.e. unattended outdoor use. I use one of their 40 watt panels in australia for charging a 12 v gell cell that runs a small Engel fridge (to keep essentials cool) while out bush. Telecom Australia uses lots of their panels for powering remote repeaters and telephones (yes I have called home from a solar powered telephone!). The panel cost around AUS$400 a couple of years ago, and on last checking the price over here (in the USA) they was cheaper, exchange rate etc. They also have more efficient panels now. The 40 watt panel is approx. 1 metre x 1/2 metre x 3 cm. best regards, -- George Scolaro george@wombat (try {pyramid|sun|vsi1|killer} !daver!wombat!george) [37 20 51 N / 122 03 07 W]
