Solar is not a magic bullet; it is a compromise like anything else. | Solar is not a magic bullet; it is a compromise like anything else. |

**Solar is expensive for the amount of power you get out of it.** It can cost several thousand dollars to get the same amount of reliable power one might might get from a residential (or campsite) outlet with a $20 extension cord. | **Solar has very high startup costs for the amount of power you get out of it.** It can cost several thousand dollars to get the same amount of reliable power one might might get from a residential (or campsite) outlet with a $20 extension cord. Over time, though, the power is "free". |

**[[electrical:solar:rationing|Minimizing power consumption]] is key** to happiness with a simple, affordable solar setup. It requires a change in mindset for most folks. Electrical power becomes a precious resource to be carefully consumed. The **path to frustration** (or at least considerable expense) involves [[hvac:solar|heating or cooling with electricity]] or trying to run household appliances in a van. | **[[electrical:solar:rationing|Minimizing power consumption]] is key** to happiness with a simple, affordable solar setup.

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**. 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. | 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. |
