Thinking about going to a grid tie solar panel sytem for a new home…how many watts would we need?

My husband and I are looking to buy a bigger a home and we’re either thinking of having an 1800 sq. ft. total electric (two story) built or going with a modular home around 1900 sq. ft. home.

How many watts would we need to power the entire house?

A really nice article by someone who has “been there, done that” can be found here: http://www.hollowtop.com/cls_html/solar_power.htm

The number of watts you need will depend on your expectations as well as the actual load drawn by appliances and lighting in hour home. The number of solar panels you will need depends on location and whether you choose a fixed-angle installation (optimized for only one day of the year!) or a sun-tracking installation (expensive!). Consult with experts in solar panel sales and installation before plunking down any cash.

In general, the only way that solar panels are economically justifiable today is if you purchase with OPM… other people’s money. Most states and the national government offer “incentives” in the form of rebates, tax credits, or outright cash if you install solar electric panels. In the article cited, these rebates virtually payed for the entire cost of the solar panels… $4.66 per watt paid minus $4.50 per watt in rebates.

For the size home you are considering, my “gut” feeling is you need at least 2000 watts capacity, and twice that amount would allow you to sell power back to the grid most of the time that the sun shines… all at taxpayer expense. What a deal!
