groSolar is heading to Burlington, VT this evening to receive a 5×5x5 Growth Award. We are one of VT’s Top 5 Fastest Growing Technology Companies in the Past 5 Years!

Bill McKibben, founder of 350.org and also a groSolar customer, was on David Letterman on Tuesday night talking about climate change, putting solar on the White House and the future of our little planet.


Bill has been involved in climate change since the 80’s and even wrote the first book on the subject back in 1989. The past two decades have seen the largest increases in carbon output during human history. For the first 10,000 years of human civilization our atmospheric carbon was about 275 parts per million (ppm). Right now we are at 392 ppm. Most climate scientists agree that we need to be at 350 ppm (hence the name of Bill’s organization).


So why aren’t we doing anything to change? Have we become complacent? Or are there enough powerful special interests in the world who don’t want to solve this problem?


Check out Bill’s interview below (and have a tissue handy to wipe away the tears of despair).

One of our customers, Bruce Pollard of Sicklerville, NJ, sent us a great email which laid out his costs and savings when installing a 4.5 kW solar electric system with groSolar. Here are the numbers:

It was just a little over a year ago that groSolar finished the installation of the 4.5kw Solar Project on our house. I thought it would be a good time to do some evaluations and see what my true saving was.

Let me lay some background. I had electric hot water heater, clothes dryer, stove, microwave, light and other normal stuff. We were using oil hot air heat but after the energy audit decided to switch to a Heat Pump with and electric back up system. Our oil cost was $3400 a year and our electric was $3168 a year. This totaled $6568.

During this past year our electric bill was $1975. Considering this was one of the coldest winters and this summer was on of the hottest we were still able to save $4593.

The cost of the heat pump was about $10,000 with the state of New Jersey giving us 50% back within 90 days of install. The savings basically paid for the cost of the heat pump in one year.

On the Solar side we spent about $39,000 with the stage grant paying $7,980. We have received over $6,000 in Federal tax credits this year and expect to get the remaining $6000 next year. We have also received the first 2 payments totaling $2,000 from selling our SREC. So we are down to $17,020. With $2,500 a year from SREC sales a for the next 4 years we are down to $7,020. With energy savings over those same 4 years of about $4,000 a year we should be ahead of the game by about $8,980.

Thank you for your assistance in getting all the details worked out. It was a pleasure working with you and groSolar.

Thanks for letting us share your numbers Bruce!

The Solar Impulse, a solar powered aircraft has completed the first night flight using only solar power. The plane flew for more than 26 hours storing solar energy during the daylight hours and utilizing that stored solar energy at night to power the plane. Read the full article on Reuters.
