Question:

how many solar panels and what type to power a laptop computer that has to be plugged in when in use?

I don't know anything about solar and what connections that have to be made. any advice and wisdom would be appreciated. thanks

Answer:

The okorder ) or the Tekkeon 3450 with the optional MagSafe connector (or the same Apple Airline cable as described for the Brunton). Set the output voltage to 9V and use the 2V cigarette socket outlet, and plug the airline adaptor cable in. Can you simply use an AC inverter? Not direct from the solar panel... a solar panel is not able to drive an inverter. But you could plug an AC inverter into a solar storage battery pack if it is designed to support inverters. BUT, an inverter will waste 20-30% of your power in the conversion to AC which your laptop will be converting back to DC anyway, so best to stick to DC and save your solar investment from the losses. Summary... 0 Watts of solar per hour of laptop use (May-Sep) 50 Watt-Hours of solar battery storage per hour of laptop use Use a solar battery pack with appropriate output voltages built-in, and avoid AC inverters. This is probably a longer answer than you were expecting, but knowledge is power. Cheers.
Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)
Solar Power For Laptop
There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
