July, 2010, was a good month for solar-generated power. Our 4.2 kW array generated 474 kWhrs of electricity.
We have had a spectacular summer to date - it's been sunny and along the coast, a cooling breeze. In addition, we've had rain showers and downpours (some with thunder and lightning) at least once a week and sometimes twice a week. This has kept our garden happy and the streams and brooks comfortably filled.
 Our architect, Steven Strong, showed up and performed maintenance on the solar roof. The aluminum straps that hold down the panels needed re-caulking after 15 years of handling the sun's heat. His work guaranteed a continued waterproof seal at all of the panel joints.
It was hot, meticulous and time-intensive work. Many thanks to Solar Design's for their continued care of our system.

Well, we received somewhat less sun than hoped for in June -our array's output: 379 kWhrs. Of course, it's a gift with no strings attached, so we gratefully accept it.
Now that we've reached the mid-way point of 2010, it's time for a celebration: 2,358 kWhrs generated which puts us on course for a 4,000+ kWhr year. We have consistently exceeded 4,000 kWhrs annually and usually end up around 4,600 kWhrs by the end of December - fingers crossed.
Have you taken the poll on the right? Our array continues its consitent output - now in its 16th year. It's definitely not 'experimental.'

Debbi embraces tanks in 1995
My guess is that I add about 50 gallons to the heat exchanger tank (it's connected to the other tank) so that the water covers the cooper tubing that runs around the top perifery of that tank. I begin to notice the tank needs refilling when our domestic hot water cools down slightly.
The well water (50 degrees) is routed through the solar thermal tank's heat exchanger where 150 degree water preheats it. It then goes to the propane hot water backup system and then into the house's hot water distribution system.

A great May for electrical generation from our 4,200 watt array: 491 kWhrs of power was harvested from the sun, which makes last month the strongest May is five years.
This meter measures the array output and I will show it each month. It was installed two and a half years after our installationn went online.
The panels show no reduction in output as we enter our 16th year at the Maine Solar House. Those who have joined our website can add their comments.

August of 2010 was the sunniest in recent memory. Not only did PV production deliver the second highest on record, but beach blankets at the local beaches were too numerous to count (guess I'll just count beach blankets from now on)!
Our PV output hit 495 kWhrs. The first 3/4 of the month was sunny and warm with a cooling sea breeze in the afternoons...the last week was outrageously hot (in the 90s for 6 straight days - two of them in September).
