This guide for a basic 450 watt solar setup is good as a template for planning your electrical system. It covers the parts and acts as a visual reference for how things are connected. For important information on calculating electricity and individual component choices, explore our electrical page. In particular, read our post on wiring your campervan before purchasing anything. Just like baking a cake, it’s good practice to be familiar with all of the steps before diving in.
450 Watts is enough to power small electronics such as laptops and cell phones as well as larger items such as TV’s, refrigerators, vent fans and possibly an induction cooktop. Keep in mind that if you plan on wiring in an alternator or generator the system layout changes a bit. It’s better to plan for them at the beginning than try to add them in later.

Total Cost of a DIY 450 Watt Solar Panel Kit:
When choosing to buy just the basics, you can expect to spend around $2000 on a 450 Watt solar kit including everything except the wires themselves (this can vary depending on how much wire and how many devices you’re using).
Alternatively, a Goal Zero Yeti kit can be purchased and includes everything except the solar panel mounting hardware. This would be the equivalent of a 100Watt solar suitcase paired with a 100Ah AGM battery and 1200 Watt inverter. Our estimate that the DIY pieces separately for this would be easily under $1000.
