If you are looking for solar panels for sale online, you have a lot to look at. Prices range from over $30,000 for a pallet of Sanyo 200 Watt solar panels all the way down to $19.50 for a kinda crappy looking solar panel on eBay. Somewhere in the middle of all of that, there may be something that suits your requirements and your budget. If you are planning to build your own solar panels, a set of 150 solar cells might sound appealing. Some come with conductive tabs attached and some do not.
The disadvantage of buying solar panels for sale online is that you cannot verify that they work. There might be some local sources for new and used solar panels in your area. Government surplus auctions, craigslist and local classified ads are all good places to start looking. Purchasing or borrowing an appropriate volt/amp meter before personally inspecting prospective purchases is a must. Be sure to set the meter to the expected output range before attaching it to a solar panel that is in full sun.
Solar panels have recently been added to the stock in many big box stores. These kits have been tailored to meet a carefully researched price point rather than engineered to meet a specific need. That being said, they might make economic sense for people with off grid cottages who are satisfied with adapting their usage to meet the output of the kit.
