Be Prepareds' smallest package at $750.00 consists of a 1200W inverter, brand unknown and modified sine wave so not good for some electronics; a 100W polycystaline solar panel and a PWM controller for it, both brand unknown; a 100 Ah 12V sealed battery, brand unknown; a plastic box and a folding dolly for moving the box.
Goal Zero's package that most closely matches it is the Yeti 1250 with a pair of 50 W solar panels in a suitcase design, no mention of the inverter but from the name I suspect a 1200W, again no specification as to make or type and a 100 Ah 12 V battery of unknown origin. Cost on this one is a whopping $1,974.94 It also calls for a solar recharge time of 24 to 48 hours of bright sunshine.
Renogy sells top line panels IMO. A 100 W Eclipse high efficiency panel (I own two) is 219.99, add in a few dollars for cables, a solar controller will run anywhere from say $50. to $150/200 depending on what you want to spend or just buy one of their ready to go suitcase set up...100W is 279.99, an inverter PSW, say $125.00 and a battery $100.00 to $200. depending on quality and brand. A little help from your friends here to nurse you through the set up and a couple of 12 V outlets and you're basically away to the races. Done on the low price range - $500.00 to $600.00
Even doing it up with some upscale products you're still cheaper than the Be Prepareds' set up, you know what the quality is on the components you used AND you get to learn something about how the power you use is created.
My vote - Renogy - I've had both the solar suitcase and now own 2 - 100W Eclipse panels.
