A New Roof and Solar Energy All in One

Is your roof getting old? Is it time to replace it? Why not also consider installing a solar energy system as part of your roof. Cutting edge technology over the last decade called solar shingles has emerged as a newer type of photovoltaic modules that can be incorporated into buildings (BIPV – see previous blog). These solar shingles have been designed to look and act like regular shingles, but have the added benefit of creating energy from the sun. These shingles use flexible thin film cells which allow them to be installed as part of the roof. These shingles help extend the normal roof life by protecting against water damage and ultraviolet rays. Also, since solar shingles replace traditional shingles, a homeowner will save on materials and will benefit from reduced electricity costs. Depending on the type of roof, solar shingles are available in different sizes and styles.

BIPV – Solar Energy with an Aesthetic Appeal

For some interested in solar energy, the look and size of the solar panels that sit atop a house or building can be an eyesore. While some like the futuristic look of the solar panels, others view a solar array as a clunky addition to a building. However, nowadays, solar panels don’t have to jut out of the exterior of a house with no regard for aesthetics. A Building Integrated Photovoltaic system (BIPV) consists of integrating photovoltaic modules into the structure of the building, most often into the roof or the façade. Unlike the traditional hard crystalline PV panels, BIPV modules include a variety of different materials that can be incorporated into the building itself. For instance, solar roof tiles can substitute for traditional shingles while generating electricity and blending right into the roof. Façade PV modules can be installed on buildings giving them a whole new chic, futuristic look. The ability to alter the transparency of solar panels can allow PV modules to replace materials that are commonly made with glass and similar materials such as windows or skylights.





These BIPV systems serve not only to create architectural appeal but also provide savings in materials that would otherwise be used and reduced electricity costs. Along with this, these systems will help protect against the weather and will be a source of clean, renewable energy.

Freedom: Off-Grid in Haiti.

Off-Grid Living in Haiti


Proud owners of a PurePoint Energy off-grid solar-electric system!




Haiti is one beautiful country with an abundance of culture, agriculture and sunshine. The country's rugged landscape is surrounded by crystal clear blue water escalating into dramatic mountains in the core. One luxury that is not readily available in this country is electricity.


According to the World Bank:



Only 12.5% of Haiti's population has access to regular electricity. These electric costumers receive an average of 10 hours of electricity per day.




This very much held true while we were in Pétionville, a suburb of Port-au Prince where electricity appeared and disappeared with no regularity. Our client is constructing a home in rural Haiti on top of a mountain with no access to grid electricity or water.

Our goal was to create a cost effective solar electric system that would meet all the energy needs of our client while being low in maintenance. We began with a thorough energy analysis - assessing the demands of both small and large appliances. The new home has been designed to be extremely energy efficient. The final design was a 2100 watt system with backup batteries.

While the house was constructed, PurePoint Energy scrutinized over each component of the system - as getting equipment last minute in Haiti is either timely and costly. Each trip to the local hardware store to pick up some bolts, nuts and other miscellaneous items took 6 hours.

Our planning paid off and the installation went as smooth as could be expected.

We look forward to doing more projects in Haiti, the Caribbean and beyond.

Getting the Most out of Your Solar Panels – Maximum Power Point Tracking

Traditionally, it was expected that a solar panel, lets say one rated at 130 watts, would only produce a portion of those watts (say only 88 watts) due to inadequate voltage levels between the panel and the battery in off grid systems. Most panels are designed to put out 16 to 18 of actual volts, while a typical battery produces somewhere around 12 volts. A standard charge controller transfers the current from the panels directly to the battery resulting in the panel voltage being dragged down to sync with the battery. Up until relatively recently this was the norm. However, with the creation of the Maximum Power Point Tracker (MPPT), solar panels have been able to produce power much closer to their optimal electric load. A MPPT is a high efficiency DC to DC converter that uses inverter technology to convert the voltage that the panel wants to work at for maximum power and turns that into more current at the voltage level of the working battery. A MPPT works to track what is called the maximum power point, which changes based on weather conditions and the time of year. Without a way of tracking this power point, it won’t be reached. Nowadays, on-grid inverters use MPPTs to maximize power from the solar panel array. For off grid systems, an MPPT charge controller is utilized to generate maximum power. More recently, MPPT charge controllers have become more affordable making it a very wise investment for any off-grid battery supported solar energy system.

Costs of a Solar Energy System Cheaper than Ever Before and Poised to Fall Further.

One of the major challenges that people face when considering a solar energy system for a residence or business can be the initial cost of the installation. It’s an unfortunate reality, but many a business and family have had to forgo their dreams of generating their power from a renewable energy source. Until now.

Since 2008 both individual states and the federal government have been stepping up their efforts to provide incentives that dramatically reduce the cost of a solar energy system. The federal government now offers a 30 % tax credit for the first year of installation. Across the nation, states have been passing legislation that decreases the upfront cost of solar energy systems. In fact, both Connecticut and New York offer some of the best incentives in the country. State incentives often come in the form of rebates passed onto customers through particular state programs. These rebates vary based on the size of the solar system and sometimes based on the area you are located in. To find a complete breakdown of the incentives in your area please follow the link and click on your state. http://www.dsireusa.org/.

And that’s not all the good news for consumers. Recently, the price of solar panels has been steadily declining since 2008, and by some estimates the price will drop as much as 40 % by 2010. The main cause of this price drop is due to the increased supply of the main ingredient in solar panels, polysilicon. This coupled with a decrease in demand for solar panels due to a shrinking economy in parts of Europe has helped drive the price down. With decreasing costs and great monetary incentives, now is the time to look into solar.

PurePoint Energy and Torrefaction

Biomass is organic material that contains stored energy from the sun. Examples of biomass are wood, plants, garbage, alcohol fuels, and landfill gases. Deriving energy from biomass will help reduce the use of fossil fuels, reduce greenhouse gas emissions, and reduce waste management problems.

There are many roadblocks when extracting energy from the typical biomass. Most unprocessed biomass are low in energy, moist, and expensive to transport. These obstacles prevent biomass fuel from growing in the renewable energy world.

Torrefaction is a new, feasible method for improving the properties of biomass fuel. It consists of slowly heating a biomass at a max temperature of 300 degrees Celsius. The end product is a solid, uniform product of low moisture content and higher energy content. This allows transportation costs to decrease, while increasing energy yield.

PurePoint Energy and The Completion of our First Wind Project

On Wednesday, August 12, 2009, the PurePoint Energy team and about a dozen students attending Greenlight Academy worked together in installing one of two wind turbines at Penfield Lighthouse in Fairfield, Connecticut.

"We're trying to show you can use solar, you can use wind, to create electricity economically, especially in remote locations," said Tom Wemyss, co-founder of PurePoint Energy.


The lighthouse is far in proximity from the shore, which rules out the possibility of a power line. With the addition of it’s new 24 volts turbine and solar panels, Penfield Lighthouse is completely green, and a prime model of how renewable energy can make sense financially and environmentally.


Working with the students of Greenlight Academy and Beacon Preservation has proven to be a valuable learning experience. We view this relationship as a microcosm for things to come, as we strive to work with others in developing a cleaner, sustainable future.


If you believe you have a windy site and are interested in being part of a wind project please call or send us an e-mail to learn how we may be able to work together.

PurePoint Energy and Meteorological Towers 101

PurePoint Energy and our partner Alternity Wind Power have installed two 190' Meteorological towers in Clearwater County, MN. This is a big milestone in our pathway to developing a 100 MW wind farm that should provide enough electricity for up to 30,000 homes.

Meteorological (MET) towers are used at potential wind energy project sites. Attached to the towers are equipment that assess the wind resource and other environmental factors that are important to determine the viability of a wind project. Important equipment include an anemometer, wind direction vanes, and temperature and pressure sensors.

Dependent data is usually statistics recorded over a minimum of one year. Wind date is taken every 10 minutes and stored at the tower base, which contains a recording and memory device called a data logger. The data collected is resourceful prior to installing a wind turbine. Educated knowledge on a site is vital for optimal wind turbine performance and getting financial great electrical generation statistics.

PurePoint Energy is currently working to educate others on renewable energy and sustainable technologies. If you believe you have a windy site are interested in being part of a wind project please call or send us an e-mail to learn how we may be able to work together.

PurePoint Energy and Tips on How to Save Energy


As a renewable energy consultant and developer, PurePoint Energy values positive environmental leadership. A key solution to preserving our environment is renewable energy. This is why PurePoint Energy is focusing our efforts in educating consumers and citizens on the benefits of going green. There are small adjustments you can make to save energy and use electricity right now!

  • Turn off unneeded lights/use energy efficient light bulbs
  • Turn off your computer at night.
  • Use microwave instead of oven for cooking meals.
  • Use laptops instead of desktops- Laptops draw 15-25 watts when used. This is compared to an astounding 150 watt of a PC.
  • Use thick curtains- Thick curtains provide better insulation, which can make a huge noticeable difference in comfort and electric bills.
  • Showers instead of baths- More hot water is used when taking baths, which results in more energy use.
  • Unplug devices from electrical outlets- Most devices still draw up to 90% of their power usage when turned off.
There are currently generous rebates and incentives to get a residential energy audit in Connecticut. Please contact PurePoint Energy 203-642-4105 to learn more on how we can help you or your organization go Green. Please visit our website at http://www.purepointenergy.com to learn more.
