Tough Winter to Make Solar Money

Just how dismal has this winter been for making money from solar power? Consider the performance of our solar panels so far. They began operation November 23, 2011. They have not performed well.

According to PVwatts , we should have generated 985 kilowatt hours in December and 1130 kilowatt hours in January. And we should have generated some in that last week of November (perhaps a quarter of the monthly 748?), but I cannot recall if the sun even poked its face out that month. For ease of calculation, let’s pretend November never happened. Because it sort of didn’t.

So our Hydro meter should read 2115 kilowatt hours for the two months.

Instead, it reads just 1489. That is 70.5 percent of what it should read. At $0.642 per kilowatt hour that MicroFIT pays, that means that this dismal weather (and perhaps a bit of the snow on the solar panels)has cost us $402.

Curse you clouds!

Let it be said that if there is a time of year when the clouds can do the least harm, it is in the winter, when the days are short. With any luck, we’ll have an extra four days of full sun the summer. Yes, just five extra days of full sun in May, June and July, can erase the trauma of winter’s clouds. It will be interesting to report back to you about what I hope will be the sunniest ever summer.

    Contact our experts to help you monitor the solar system. What kind of inverters do you use? String?

    Hi amabaie,

    Love the blog! I just found it and spent the last couple of hours reading some of your older posts. I was wondering what you thought about the recent news about cutbacks to the microfit program? Apologies if you’ve already covered this in a previous post…

    Cheers,
    Craig
