Given these limitations why do we do spend so much time and money on solar? Because having power off-grid, however expensive and limited, can make a //huge// difference in quality of life. Solar is silent, works for decades, and is always working when the sun is shining.((portable solar only produces when deployed)) | Given these limitations why do we do spend so much time and money on solar?

| First things first: Bill needed some idea of [[electrical:solar:sizing#your_daily_power_needs|how much power he actually needed each day]]. |
| |
| One way to figure it out is to [[electrical:solar:builds|see what configurations other people are running successfully in their own camper]] right now. The gamut runs from 100W to 1000W+, with 200W being the most common. |

| |
| The details of Bill's logic and math has been [[electrical:solar:daily-gentle|moved to its own page]], but for now we will stipulate he came up with a daily requirement of **91Ah** of usable battery capacity for each 24hr period. On average he will consume that much power each day, and will have to replace that amount((and a little bit more due to charging inefficiencies)) from the sun. |

So how did he pick those components? How did he know they would work? Where did he start? [[electrical:solar:builds|What are other people doing?]] How the heck does anyone untangle this stuff?((by mastering small sections at a time!)) | So how did he pick those components?
