pvmarch15Now we're cooking! March PV electrical output was 477 kWhrs! That brings us to a year-to-date total of 1,076 kWhrs which puts us right on course for another 4,000+ kWhr year. The significance of these numbers is that in the 20 years of operation, our PV output has not diminished thanks to the industrial quality of the panels and the efficiency of the inverters. There's still a foot of snow in some parts of our land, but it is inexorably diminishing. Still a cold spring.

This month I'd like to celebrate the 100% solar achievement of the Wells Reserve at Lauholm in Wells, Maine. This federal estuary research lab has proudly installed PV panels on three of its buildings (along with a ground-mount array). Senator Angus King (I) of Maine threw the 'switch' at dedication ceremonies. The aerials, at the beginning and end, as well as the overall coverage were contributed by Maine HDTV (I'm a partner in their aerial photography division and a former Laudholm Trust board member).

The reserve had planned for years to make this leap - with federal money and donations from Laudholm Trust, the goal was reached on-budget and two years early. You can read about the facility, which will generate 73,000 kWhrs of 'free' electricity annually, on the reserve's website. "Where there's a will, there's a way!"

winter15Winter is a blast...literally! Snow, wind, freezing temperatures...but warmth inside our house. Wikipedia defines winter as: "...caused by the axis of the Earth in that hemisphere being oriented away from the Sun." Well, I think the axis has been even further tilted from the Sun because of the weight of the snow - averaging a total of 3-4 feet to date, and knowing New England - there's still more to come.

One of the great inventions of our time is the snow blower - without it, no access to the front door and the backup propane tanks until Spring! I'm not sure it's just a Maine thing, but several years ago my neighbor said he didn't need his snow blower any more and wondered if I wanted it. Not wanting to insult his generosity, I immediately said, "yes." As you can see the pathway is a bit crooked but not bad for an amateur.

pvfeb15Our photovoltaic panels continue to crank out electricity. February's output was 286 kWhrs. That's lower that our normal February generation (usually around 350 kWhrs) due primarily to the parade of snow storms that kept the sun from shinning. But when it's out, it's powerful. Today, for example, we generated 21.5 kWhrs!

tempfeb15

Note the inside temperature today  - a high of 77.4. That's due primarily to the passive solar gain of our home. The sun shone from sunrise (0 degrees) to sunset (28 degrees) which caused the solar tanks in the basement to heat up to 148 degrees - ample 'fuel' for any overnight heat we might need. That's called a renewable resource!

PV Array Output

pvdec14Well, here we are starting a new year. Our PV output goal has been 4,000+ kWhrs/year and a check of the meter shows our 4,200 watt array generated 4,115 kWhrs in 2014. Phew! November and December were lousy months for sunshine - had we received the normal amount of sun, we would have easily exceeded 4,200, but the array and inverters continue to work well. Output in 2013 was 4,190.

Plug-in Prius 

fuelly14I'm now into the last year of my Prius Plug-In lease. Overall mileage is currently 164.3 mpg but in the summertime I've averaged over 300 mpg. It's all about range. This year, the temperature got into the 90s only one or two days which meant that the EV range peaked under 14 miles. The range is in its downward slope for the next few months - right now it's 10.4 miles.

Overview:

pvjan152015 got off to a good start with a PV generation of 313 kWhrs. It would have been even higher if two snowstorms hadn't decided to 'dump' on us. That's not sour grapes, just a little perspective. In fact, it's snowing now and if the forecast is right, today's 12 inches will be added to the combined total of 21 inches from last week for a 7-day accumulation of 33 inches. Now that's winter.

Solar Living in Maine During the Winter:

You've heard it before, but there is great joy living in a solar home. The benefits in the winter are considerable:

  • Passive solar gain through the south-facing windows - yielding an indoor temperature in the high 70s on sunny days.
  • Having to open the windows to 'manage' the extra heat.
  • Enjoying our wood stove when the temperature goes down below 20 at night.
  • Enjoying our radiant heat in the floors and shower in the morning - much of it from our 1,000 gallons of hot water generated by the solar thermal panels on the roof.
  • Trusting that if the power goes out, our battery backup system will provide power to our necessary loads until the grid power returns.
  • Etc, etc, etc!

    Here's a video shot several years ago about Solar Living in Maine:

pvjune14Solar Report

June was a fantastic month for sun. It now rockets our PV output to a sweet 2,247 kWhrs for the first six months of the year. That's a result of a 456 kWhr month (plus two days). No measureable loss of output from the panels since installation in 1995. Now that's dependability!

Plugin Prius

priusjuly14The good news is that my car has now reached the 13 mile range on the batteries. That gives me considerable flexibility is traveling to and from local towns. You might notice that my current tank of gas is registering 356 mpg!  Hope the range will top out around 14 by late July. Looks like I won't need any more fuel at least until September.

Gardening

gardenjuly14I added another raised bed this spring to my 'farm' and should soon see some squash and cucumbers blossoms. Already the tomatoes are beginning to set small fruit as are the peppers. We've been enjoying our lettuce, though soon they'll be going to see. Small is better is so many ways!
