Living Off-Grid: Our Solar Costs

Our Solar Equipment

Solar costs have so many variables, it is difficult to put an exact number on the cost of solar power. It will vary greatly from household to household and state to state. There are currently federal tax credits to consider and some states also offer tax credits or deductions to install solar power.

Added to that, solar panels will last about 25 years, inverters 15–20 years and batteries anywhere from 10–15 years. The good news is that all three of those components are lasting longer all the time and the purchase cost is going down as more and more products flood the market and solar becomes more popular to consumers.

There are a lot of numbers out there in cost per kilowatt of every kind of power including solar. Many of the solar numbers being quoted are outdated so if you are doing your own research be careful of that. There is a general consensus that the costs are going down and will continue to do so.

Another problem you will run into is that the cost numbers that are published don’t include all of the costs. For example, Washington State has one of the lowest basic electrical rates in the country but by the time the state and local authorities get done tacking on their add-ons the price goes up considerably.

We decided to take a look at our own costs which we can identify now that we have been operating for two years, going on three.

Solar power facilities are actually cheaper to create than fossil fuel and other plants.I was able to save thousands of dollars on my solar panel kit and installation by using By entering my zip code, I got free quotes from the best solar installers in my area. I hear they serve all of North America so if your looking to go solar, I advise you check them out. Here's their link:

Agreed. As in Nature, businesses that can't compete should be allowed to go extinct.... But the "tax breaks " you listed above only add up to ~$0.6 billion while the fed govt, biggest parasite of all, spent $1,200 billion more than it took in during each of the past 4 yrs and projects to repeat it again for the next four yrs....Actually, taxes on corporations is double taxation because the profits are taxed again when they're payed out as dividends....We have a spending problem, not a taxation problem. The same Liberals who cry for sustainability in our environmental matters seem to forget all about it when it comes to govt spending.

Dean, I responded in detail yesterday but I don't see my post today so I will repeat it here. I have 8 each 215 watt panels. 12 each 2 volt Solar One batteries wired for a 24 volt system. The batteries are rated at 1160 Amp Hours. I also have a 4000 Watt Xantrex inverter and an Apollo T-80 HV Charge Controller.
